INTRODUCTION

Sometimes it's a little hard to get people to realize that not only has the world changed in the past, but that it is changing now, and will change in the future. In fact, it takes something on the order of an atomic bomb to blast them out of their congenital complacency.

And it took the literally shocking violence of the atomic bomb to make the general public understand the fact that science-fiction is not "pseudo-science" (that's what you find in Sunday Supplements—fiction, pretending to be science) but an entirely different breed of thing—fiction stories based on science, and attempting to extrapolate the curves of past development into future years. On August 6, 1945, people suddenly discovered that that fool fantasy stuff about atomic bombs hadn't been quite so fantastic as they had—well, to be brutally frank, hoped.

Their immediate reactions were that a good guess or two, a chance, coincidental correspondence between fiction-fantasy and fact, didn't mean much. Still, relatively few people have learned to understand how science-fiction originates—why it does successfully predict.

The answer is, actually, that science-fiction's prophecy is to a large extent phony. It isn't prophecy at all, not in the true sense. It's more like the astronomer's prophecy that there will be an eclipse of the sun visible for so many seconds, on such and such a day, at a specified point. The astronomer's prediction is based on information he has that is not generally recognized—though anyone who wants to get it can go dig it out of the text books.

The science-fiction author predicts in the same general way. With the knowledge of what has been accomplished in the laboratories, and a general understanding of what people have wanted in the past, want today, and will probably want in the future, it's not hard to guess how those laboratory facts will be applied.

By 1915 it was generally known among scientists that there was an enormous store of energy locked in every pound of matter. Men have, sadly, wanted more deadly killing instruments for all human history—and will pay much more for a means of killing an enemy than they will to save a friend's life. From these facts it's a simple prediction that atomic energy will some day be released—and probably first in the form of a bomb.

Science-fiction made such predictions. When the laboratories found U-235 was probably capable of a chain reaction, the science-fictioneer began saying U-235 bombs instead of the more generalized "atomic" bomb.

The essentials for good prophetic fiction—and hence good science-fiction—are fairly easily stated.

That mind must be intimately acquainted with one or more technologies—and by that I mean both the branch of theoretical science and that branch's engineering applications as of today.

Imagination is a third requirement; if imagination is put first, fantasy, not science-fiction, results.

An understanding of how political and social set-ups react to technological changes must be added, for the best types of science-fiction.

George O. Smith's "Venus Equilateral" series represents an excellent progressive development of a single line of extrapolation.

George O. Smith is a radio engineer; at the time the Venus Equilateral series started, he was working on radar equipment and Army communications radio units. It was only natural that he should pick the field of communications engineering as his line for development—he was intimately acquainted with the problems and possibilities of that field, and with the past history of the art.

"QRM Interplanetary," the first of the stories, appeared in Astounding Science-Fiction to start the series; typically, it serves merely to introduce the concept of the equilateral relay station as a necessary link in interplanetary communications. But the story has been so constructed that the working out of its plot gives a good concept of the general nature of the station, and of its functioning. Still, the story is essentially simply a suggestion that interplanetary communications will require the construction of a station in space to relay messages.

The immediately following stories of the series introduce successive problems of the purely technical art; only gradually are the associated social and political reactions of the rest of that civilization of the future brought in. From the start, the author's problem has been simplified by picking a small, almost wholly isolated segment of the culture, so that only the technology itself need be discussed.

As the series develops, however, more and more the social and political effects of the developments are brought into the picture, until, in the end, practically nothing but the social-political effects remain. The final story of the series to appear in Astounding Science-Fiction was devoted entirely to the cultural, rather than technical, problems of the matter transmitter.

In essence, Venus Equilateral represents the basic pattern of science-fiction—which is, equally, the basic pattern of technology. First starting from the isolated instance, the effects spread outward through the culture. Scientific methodology involves the proposition that a well-constructed theory will not only explain every known phenomenon, but will also predict new and still undiscovered phenomena. Science-fiction tries to do much the same—and write up, in story form, what the results look like when applied not only to machines, but to human society as well.

The science-fiction writer can be extremely accurate in the guesses he makes of future progress—and yet there are factors that may make a complete failure of his prediction.

George O. Smith is a radio engineer; radio is his field of technology. As such, his predictions tend to be based on the extrapolation of a single line of activity. But it may be that all his predictions may come to nothing due to a development in an entirely separate field of technical progress. It might be, for instance, that Dr. Rhine's work on extra-sensory perception developed into a science, that equipment was developed capable of recording, receiving, amplifying and broadcasting whatever strange energy form is involved—and that telepathy completely displaced radio engineering. The atomic pile is the only form of nuclear energy machine we have available; because war-time engineering was operating under forced draft, and war-time basic science was in abeyance, we have no basic science from which to predict more advanced forms of energy-harnessing devices. But it is quite conceivable that, long before we reach Mars and Venus to establish colonies, we will achieve the ultimate in energy-harnesses for atomic energy—a small, sealed box with two projecting terminals from which unlimited electric power can be drawn directly.

Also, any extrapolation whatsoever is, necessarily, based on the implied, but unstated proposition, "If things go on as they have been...." The proposition is, right now, open to serious question. For one thing, whenever science becomes engineering, it meets legislation made by men. Now the laws of Nature are predictable, understandable, and absolute. They don't depend on the viewpoint of the individual, or the social theory popular at the time, or the Majority Leader's severe chronic indigestion. The patent law very definitely does. At the moment, as a matter of fact, an extrapolation of the trend of patent law suggests that half the Venus Equilateral series will be rendered plotless; there won't be any patents.

The science-fiction writer is, therefore, faced with a simply stated problem: Taking off from the solid ground of known laboratory science, sighting along the back-track of past experience, he launches into the future.

But he may come down in a never-will-be future, because somebody harnessed telepathy, and threw civilization off on an entirely unexpected track. Or because the Supreme Court, currently invalidating 24 out of every 25 patents brought before it, has eliminated the institution of patents. Or because a new social theory has decided that no scientific advance should be permitted for a period of 250 years while a great program of meditation and navel-inspection instead of Naval inspection is pushed forward.

Nevertheless, science-fiction can be not only fun, but an extremely valuable experience. If a friend steps out of a dimly lighted doorway it may provoke a "Yipe!" of momentary fear, or a casual "Hi," dependent entirely on whether or not you expected to meet him there.

The science-fiction reader is a lot less apt to jump in senseless fear and alarm when a new process comes from some unexpected doorway—he'll have been expecting it, and recognize a friend or an enemy—which can be very helpful to survival.

QRM—INTERPLANETARY

Korvus, the Magnificent, Nilamo of Yoralen, picked up the telephone in his palace and said: "I want to talk to Wilneda. He is at the International Hotel in Detroit, Michigan."

"I'm sorry, sir," came the voice of the operator. "Talking is not possible, due to the fifteen-minute transmission lag between here and Terra. However, teletype messages are welcome."

Her voice originated fifteen hundred miles north of Yoralen, but it sounded as though she might be in the next room. Korvus thought for a moment and then said: "Take this message: 'Wilneda: Add to order for mining machinery one type 56-XXD flier to replace washed-out model. And remember, alcohol and energy will not mix!' Sign that Korvus."

"Not mister!" yelled the monarch. "I am Korvus the Magnificent! I am Nilamo of Yoralen!"

"Yes, your magnificence," said the operator humbly. It was more than possible that she was stifling a laugh, which knowledge made the little man of Venus squirm in wrath. But there was nothing he could do about it, so he wisely said nothing.

To give Korvus credit, he was not a pompous little man. He was large—for a Venusian—which made him small according to the standards set up by Terrestrians. He, as Nilamo of Yoralen, had extended the once-small kingdom outward to include most of the Palanortis Country which extended from 23.0 degrees North Latitude to 61.7 degrees, and almost across the whole, single continent that was the dry land of Venus.

So Korvus' message to Terra zoomed across the fifteen hundred rocky miles of Palanortis to Northern Landing. It passed high across the thousand-foot-high trees and over the mountain ranges. It swept over open patches of water, and across intervening cities and towns. It went with the speed of light and in a tight beam from Yoralen to Northern Landing, straight as a die and with person-to-person clarity. The operator in the city that lay across the North Pole of Venus clicked on a teletype, reading back the message as it was written.

"The message will be in the hands of your representative Wilneda within the hour."

The punched tape from Operator No. 7's machine slid along the line until it entered a coupling machine.

The coupling machine worked furiously. It accepted the tapes from seventy operators as fast as they could write them. It selected the messages as they entered the machine, placing a mechanical preference upon whichever message happened to be ahead of the others on the moving tapes. The master tape moved continuously at eleven thousand words per minute, taking teletype messages from everywhere in the Northern Hemisphere of Venus to Terra and Mars. It was a busy machine; even at eleven thousand words per minute it often got hours behind.

The synchronous-keyed signal from the coupling machine left the operating room and went to the transmission room. It was amplified and sent out of the city to a small, squat building at the outskirts of Northern Landing.

It was hurled at the sky out of a reflector antenna by a thousand kilowatt transmitter. The wave seared against the Venusian Heaviside Layer. It fought and it struggled. And, as is the case with strife, it lost heavily in the encounter. The beam was resisted fiercely. Infiltrations of ionization tore at the radio beam, stripping and trying to beat it down.

But man triumphed over nature. The megawatt of energy that came in a tight beam from the building at Northern Landing emerged from the Heaviside Layer as a weak, piffling signal. It wavered and it crackled. It wanted desperately to lie down and sleep. Its directional qualities were impaired, and it wabbled badly. It arrived at the relay station tired and worn.

One million watts of ultra-high frequency energy at the start, it was measurable in microvolts when it reached a space station, only five hundred miles above the city of Northern Landing.

The signal, as weak and as wabbly as it was, was taken in by eager receptors. It was amplified. It was dehashed, de-staticked and deloused. And once again, one hundred decibels stronger and infinitely cleaner, the signal was hurled out on a tight beam from a gigantic parabolic reflector.

Across sixty-seven million miles of space went the signal. Across the orbit of Venus it went in a vast chord. It arrived at the Venus Equilateral Station with less trouble than the original transmission through the Heaviside Layer. The signal was amplified and demodulated. It went into a decoupler machine where the messages were sorted mechanically and sent, each to the proper channel, into other coupler machines. Beams from Venus Equilateral were directed at Mars and at Terra.

The Terra beam ended at Luna. Here it again was placed in the two-component beam and from Luna it punched down at Terra's Layer. It emerged into the atmosphere of Terra, as weak and as tired as it had been when it had come out of the Venusian Heaviside Layer. It entered a station in the Bahamas, was stripped of the interference, and put upon the land beams. It entered decoupling machines that sorted the messages as to destination. These various beams spread out across the face of Terra; the one carrying Korvus' message finally coming into a station at Ten Mile Road and Woodward. From this station at the outskirts of Detroit, it went upon land wires downtown to the International Hotel.

The teletype machine in the office of the hotel began to click rapidly. The message to Wilneda was arriving.

And fifty-five minutes after the operator told Korvus that less than an hour would ensue, Wilneda was saying, humorously, "So, Korvus was drunk again last night—"

Completion of Korvus' message to Wilneda completes also one phase of the tale at hand. It is not important. There were a hundred and fifty other messages that might have been accompanied in the same manner, each as interesting to the person who likes the explanation of the interplanetary communication service. But this is not a technical journal. A more complete explanation of the various phases that a message goes through in leaving a city on Venus to go to Terra may be found in the Communications Technical Review, Volume XXVII, number 8, pages 411 to 716. Readers more interested in the technical aspects are referred to the article.

But it so happens that Korvus' message was picked out of a hundred-odd messages because of one thing only. At the time that Korvus' message was in transit through the decoupler machines at The Venus Equilateral Relay Station, something of a material nature was entering the air lock of the station.

Don Channing looked up at the indicator panel in his office and frowned in puzzlement. He punched a buzzer and spoke into the communicator on his desk.

"I know that. But I've been expecting someone ever since John Peters retired last week. You know why."

"You hope to get his job," said the girl in an amused voice. "I hope you do. So that someone else will sit around all day trying to make you retire so that he can have your job!"

"No, but when the word came that he was thinking of it, you began to think about taking over. Don't worry, I don't blame you." There was quite a protracted silence, and then her voice returned, "The visitor is a gentleman by the name of Francis Burbank. He came out in a flitter with a chauffeur and all."

"I think that he's here to lay down the law! You'll have to get out of Peters' office, if his appearance is any guide."

There was some more silence. The communicator was turned off at the other end, which made Channing fume. He would have preferred to hear the interchange of words between his secretary and the newcomer. Then, instead of having the man announced, the door opened and the stranger entered. He came to the point immediately.

"Then I have some news for you, Dr. Channing. I have been appointed Director by the Interplanetary Communications Commission. You are to resume your position as Electronics Engineer."

"Oh?" said Channing. "I sort of believed that I would be offered that position."

"There was a discussion of that procedure. However, the Commission decided that a man of more commercial training would better fill the position. The Communications Division has been operating at too small a profit. They felt that a man of commercial experience could cut expenses and so on to good effect. You understand their reasoning, of course," said Burbank.

"Well, it is like this. They know that a scientist is not usually the man to consider the cost of experimentation. They build thousand-ton cyclotrons to convert a penny's worth of lead into one and one-tenth cents' worth of lead and gold. And they use three hundred dollars' worth of power and a million-dollar machine to do it with.

"They feel that a man with training like that will not know the real meaning of the phrase, 'cutting expenses.' A new broom sweeps clean, Dr. Channing. There must be many places where a man of commercial experience can cut expenses. I, as Director, shall do so."

"I can't say that. It is probably not your fault. I cannot feel against you, but I do feel sort of let down at the decision of the Commission. I have had experience in this job."

"The Commission may appoint you to follow me. If your work shows a grasp of commercial operations, I shall so recommend."

"I never drink. And I do not believe in it. If it were mine to say, I'd prohibit liquor from the premises. Venus Equilateral would be better off without it."

"This is Mr. Burbank. His position places him in control of this office. You will, in the future, report to him directly. The report on the operations, engineering projects, and so on that I was to send in to the Commission this morning will, therefore, be placed in Mr. Burbank's hands as soon as possible."

"Yes, Dr. Channing." Her eyes held a twinkle, but there was concern and sympathy in them, too. "Shall I get them immediately?"

"Then give them to Mr. Burbank." Channing turned to Burbank. "Miss Westland will hand you the reports I mentioned. They are complete and precise. A perusal of them will put you in grasp of the situation here at Venus Equilateral better than will an all-afternoon conference. I'll have Miss Westland haul my junk out of here. You may consider this as your office, it having been used by Dr. Peters. And, in the meantime, I've got to check up on some experiments on the ninth level." Channing paused. "You'll excuse me?"

"That will be all right. The autocall can find me anywhere on Venus Equilateral, if I'm not at the place Miss Westland calls."

"Nope. You are to stay here and be a nice, good-looking Mata Hari. This bird seems to think that he can run Venus Equilateral like a bus or a factory. I know the type, and the first thing he'll do is to run the place into a snarl. Keep me informed of anything complicated, will you?"

"I'm going down and get Walt Franks. We're going to inspect the transparency of a new type of glass."

"Not today," he grinned. "Your new boss does not believe in the evils of looking through the bottom of a glass. We must behave with decor. We must forget fun. We are now operating under a man who will commercialize electronics to a fine art."

"I'm not going to drink that much. Walt and I need a discussion," he said. "And in the meantime, haul my spinach out of the office, will you, and take it back to the electronics office? I'll be needing it back there."

Channing left to go to the ninth level. He stopped long enough to collect Walt Franks.

Only one thing stuck in Franks' mind. "Did you say that he might close Joe's?" asked Franks.

"Alone?" snorted Channing. The barroom was half filled with people, being the only drinking establishment for sixty-odd million miles.

"That would be desirable. But I think he is here to stay. Darn it all, why do they have to appoint some confounded political pal to a job like this? I'm telling you, Walt, he must weigh two hundred if he weighs a pound. He holds his stomach on his lap when he sits down."

Walt looked up and down Channing's slender figure. "Well, he won't be holding Westland on his lap if it is filled with stomach."

"—during working hours!" finished Channing. He grinned at Franks and ordered another beer. "And how is the Office of Beam Control going to make out under the new regime?"

"I'll answer that after I see how the new regime treats the Office of Beam Control," answered Franks. "I doubt that he can do much to bugger things up in my office. There aren't many cheaper ways to direct a beam, you know."

"But what I can't understand is why they didn't continue you in that job. You've been handling the business ever since last December when Peters got sick. You've been doing all right."

"Doing all right just means that I've been carrying over Peters' methods and ideas. What the Commission wants, apparently, is something new. Ergo the new broom."

"Personally, I like that one about the old shoes being more comfortable," said Franks. "If you say the right word, Don, I'll slip him a dose of high voltage. That should fix him."

"I think that the better way would be to work for the bird. Then when he goes, I'll have his recommendation."

"Phooey," snorted Franks, "They'll just appoint another political pal. They've tried it before and they'll try it again. I wonder what precinct he carries."

The telephone rang in the bar, and the bartender, after answering, motioned to Walt Franks. "You're wanted in your office," said the bartender. "And besides," he told Channing, "if I'm going to get lunch for three thousand people, you'd better trot along, too. It's nearly eleven o'clock, you know, and the first batch of two hundred will be coming in."

Joe was quite inaccurate as to the figures. The complement of Venus Equilateral was just shy of twenty-seven hundred. They worked in three eight-hour shifts, about nine hundred to a shift. They had their breakfast, lunch, and dinner hours staggered so that at no time was there more than about two hundred people in the big lunchroom. The bar, it may be mentioned, was in a smaller room at one end of the much larger cafeteria.

The Venus Equilateral Relay Station was a modern miracle of engineering if you liked to believe the books. Actually, Venus Equilateral was an asteroid that had been shoved into its orbit about the Sun, forming a practical demonstration of the equilateral triangle solution of the Three Moving Bodies. It was a long cylinder, about three miles in length by about a mile in diameter.

In 1946, the United States Army Signal Corps succeeded in sending forth and receiving in return a radar signal from the moon. This was an academic triumph; at that time such a feat had no practical value. Its value came later when the skies were opened up for travel; when men crossed the void of space to colonize the nearer planets Mars and Venus.

They found then that communication back and forth depended upon the initial experiment in 1946.

But there were barriers, even in deep space. The penetration of the Heaviside Layer was no great problem. That had been done. They found that Sol, our sun, was often directly in the path of the communications beam because the planets all make their way around Sol at different rates of speed.

All too frequently Mars is on the opposite side of the sun from Terra, or Sol might lie between Venus and Mars. Astronomically, this situation where two planets lie on opposite sides of the sun is called Major Opposition, which is an appropriate name even though those who named it were not thinking in terms of communications.

To circumvent this natural barrier to communications, mankind made use of one of the classic solutions of the problem of the Three Moving Bodies, in which it is stated that three celestial objects at the corners of an equilateral triangle will so remain, rotating about their common center of gravity. The equilateral position between the sun and any planet is called the "Trojan" position because it has been known for some time that a group of asteroids precede and follow Jupiter around in his orbit. The "Trojan" comes from the fact that these asteroids bear the well known names of the heroes of the famous Trojan War.

To communicate around the sun, then, it is only necessary to establish a relay station in the Trojan position of the desired planet. This will be either ahead or behind the planet in its orbit; and the planet, the sun, and the station will form an equilateral triangle.

There was little of the original asteroid. At the present time, the original rock had been discarded to make room for the ever-growing personnel and material that were needed to operate the relay station. What had been an asteroid with machinery was now a huge pile of machinery with people. The insides, formerly of spongy rock, were now neatly cubed off into offices, rooms, hallways, and so on, divided by sheets of steel. The outer surface, once rugged and forbidding, was now all shiny steel. The small asteroid, a tiny thing, was gone, the station having overflowed the asteroid soon after men found that uninterrupted communication was possible between the worlds.

Now the man-made asteroid carried twenty-seven hundred people. There were stores, offices, places of recreation, churches, marriages, deaths, and everything but taxes. Judging by its population, it was a small town.

Venus Equilateral rotated about its axis. On the inner surface of the shell were the homes of the people—not cottages, but apartmental cubicles, one, two, three, six rooms. Centrifugal force made a little more than one Earth G of artificial gravity. Above this outer shell of apartments, the offices began. Offices, recreation centers, and so on. Up in the central portion where the gravity was nil or near-nil, the automatic machinery was placed. The servo-gyroscopes and their beam finders, the storerooms, the air plant, the hydroponic farms, and all other things that needed little or no gravity for well-being.

This was the Venus Equilateral Relay Station, sixty degrees ahead of the planet Venus, on Venus' orbit. Often closer to Terra than Venus, the relay station offered a perfect place to relay messages through whenever Mars or Terra were on the other side of the sun. It was seldom idle, for it was seldom that Mars and Venus were in such a position that direct communication between all the three planets was possible.

This was the center of Interplanetary Communications. This was the main office. It was the heart of the Solar System's communication line, and as such, it was well manned. Orders for everything emanated from Venus Equilateral. It was a delicate proposition, Venus Equilateral was, and hence the present-on-all-occasions official capacities and office staff.

This was the organization that Don Channing hoped to direct. A closed corporation with one purpose in mind: Interplanetary Communication!

Channing wondered if the summons for Walt Franks was an official one. Returning to the electronics office, Don punched the communicator and asked: "Is Walt in there?"

"Better shut it off," warned Don. "Burbank isn't foolish, you know, and there are pilot lights and warning flags on those things to tell if someone has the key open. I wouldn't want to see you fired for listening-in."

"If I'm betting on the right horse," said Channing, "this will be interesting for all before it is finished."

Seven days went by in monotonous procession. Seven days in a world of constant climate. One week, marked only by the changing of work shifts and the clocks that marked off the eight-hour periods. Seven days unmarred by rain or cold or heat. Seven days of uninterrupted sunshine that flickered in and out of the sealed viewports with eye-searing brilliance, coming and going as the station rotated.

But in the front offices, things were not serene. Not that monotony ever set in seriously in the engineering department, but that sacred sanctum of all-things-that-didn't-behave-as-they-should found that even their usual turmoil was worse. There was nothing that a person could set his fingers on directly. It was more of a quiet, undercover nature. On Monday Burbank sent around a communiqué removing the option of free messages for the personnel. On Tuesday he remanded the years-long custom of permitting the supply ships to carry, free, packages from friends at home. On Wednesday, Francis Burbank decided that there should be a curfew on the one and only beer emporium. "Curfew" was a revision made after he found that complete curtailing of all alcoholic beverages might easily lead to a more moral problem; there being little enough to do with one's spare time. On Thursday, he set up a stiff-necked staff of censors for the moving picture house. On Friday, he put a tax on cigarettes and candy. On Saturday, he installed time clocks in all the laboratories and professional offices, where previous to his coming, men had come for work a half hour late and worked an hour overtime at night.

"Look," he said, "for years we have felt that any man, woman, or child that was willing to come out here was worth all the freedom and consideration that we could give them. What about this damned tax on cigarettes? And candy? And who told you to stop our folks from telling their folks that they are still in good health? And why stop them from sending packages of candy, cake, mementoes, clothing, soap, mosquito dope, liquor, or anything else? And did you ever think that a curfew is something that can be applied only when time is one and the same for all? On Venus Equilateral, Mr. Burbank, six o'clock in the evening is two hours after dinner for one group, two hours after going to work for the second group, and mid-sleep for the third. Then this matter of cutting all love scenes, drinking, female vampires, banditry, bedroom items, murders, and sweater girls out of the movies? We are a selected group and well prepared to take care of our morality. Any man or woman going offside would be heaved out quick. Why, after years of personal freedom, do we find ourselves under the authority of a veritable dictatorship?"

Francis Burbank was not touched. "I'll trouble you to keep to your own laboratory," he told Channing. "Perhaps your own laxity in matters of this sort is the reason why the Commission preferred someone better prepared. You speak of many things. There will be more to come. I'll answer some of your questions. Why should we permit our profits to be eaten up by people sending messages, cost-free, to their acquaintances all over the minor planets? Why should valuable space for valuable supplies be taken up with personal favors between friends? And if the personnel wants to smoke and drink, let them pay for the privilege! It will help to pay for the high price of shipping the useless items out from the nearest planet—as well as saving of precious storage space!"

"You may find it difficult to hire people to spend their lives in a place that offers no sight of a sky or a breath of fresh air. The people here may go home to their own planets to find that smell of fresh, spring air is more desirable than a climate that never varies from the personal optimum. I wonder, occasionally, if it might not be possible to instigate some sort of cold snap or a rainy season just for the purpose of bringing to the members of Venus Equilateral some of the surprises that are to be found in Chicago or New York. Hell, even Canalopsis has an occasional rainstorm!"

"Return to your laboratory," said Burbank coldly. "And let me run the station. Why should we spend useful money to pamper people? I don't care if Canalopsis does have an occasional storm, we are not on Mars, we are in Venus Equilateral. You tend to your end of the business and I'll do as I deem fitting for the station!"

Channing mentally threw up his hands and literally stalked out of the office. Here was a close-knit organization being shot full of holes by a screwball. He stamped down to the ninth level and beat upon the closed door of Joe's. The door remained closed.

Channing beat with his knuckles until they bled. Finally a door popped open down the hallway fifty yards and a man looked out. His head popped in again, and within thirty seconds the door to Joe's opened and admitted Channing.

"The next time you want in," Joe informed him, "knock on 902 twice, 914 once, and then here four times. We'll let you in. And now, don't say anything too loud." Joe put a finger to his lips and winked broadly. "Even the walls listen," he said in a stage whisper.

He led Channing into the room and put on the light. There was a flurry of people who tried to hide their glasses under the table. "Never mind," called Joe. "It's only Dr. Channing."

"I want something stiff," Channing told Joe. "I've just gone three rounds with His Nibs and came out cold."

Some people within earshot asked about it. Channing explained what had transpired. The people seemed satisfied that Channing had done his best for them. The room relaxed into routine.

The signal knock came on the door and was opened to admit Walt Franks and Arden Westland. Franks looked as though he had been given a stiff workout in a cement mixer.

"You've been working too hard," Channing chided him gently. "This is the wrong time to mention it, I suppose, but did that beam slippage have anything to do with your condition—or was it vice versa?"

"You know that I haven't anything to do with the beam controls personally," said Franks. He straightened up and faced Channing defiantly.

"Mastermind, up there, called me in to see if there were some manner or means of tightening the beam. I told him, sure, we could hold the beam to practically nothing. He asked me why we didn't hold the beam to a parallel and save the dispersed power. He claimed that we could reduce power by two to one if more of it came into the station instead of being smeared all over the firmament. I, foolishly, agreed with him. He's right. You could. But only if everything is immobilized. I've been trying to work out some means of controlling the beam magnetically so that it would compensate for the normal variations due to magnetic influences. So far I've failed."

"It can't be done. I know, because I worked on the problem for three years with some of the best brains in the system. To date, it is impossible."

A click attracted their attention. It was the pneumatic tube. A cylinder dropped out of the tube, and Joe opened it and handed the enclosed paper to Franks.

Walt smiled wearily and said: "A good secretary is a thing of beauty. A thing of beauty is admired and is a joy forever. Jeanne is both. She is a jewel."

"It is another communiqué from our doting boss. He is removing from my control the odd three hundred men I've got working on Beam Control. He is to assume the responsibility for them himself. I'm practically out of a job."

"Is that so bad?" asked Channing. "All you've got to do is to listen carefully and do as you're told. We have to answer to the bird, too."

"Yeah," said Arden, "but you fellows don't have to listen to a dopey guy ask foolish questions all day. It's driving me silly."

"What I'd like to know," murmured Franks, "is what is the idea of pulling me off the job? Nuts, I've been on the Beam Control for years. I've got the finest crew of men anywhere. They can actually foresee a shift and compensate for it, I think. I picked 'em myself and I've been proud of my outfit. Now," he said brokenly, "I've got no outfit. In fact, I have darned little crew left at all. Only my dozen lab members. I'll have to go back to swinging a meter myself before this is over."

It was quite a comedown. From the master of over three hundred highly paid, highly prized, intelligent technicians, Walt Franks was now the superintendent of one dozen laboratory technicians. It was a definite cut in his status.

Channing finished his drink and, seeing that Franks' attention was elsewhere, he told Arden: "Thanks for taking care of him, but don't use all your sympathy on him. I feel that I'm going to need your shoulder to cry on before long."

"Any time you want a soft shoulder," said Arden generously, "let me know. I'll come a-running."

Channing went out. He roamed nervously all the rest of the day. He visited the bar several times, but the general air of the place depressed him. From a place of recreation, laughter and pleasantry, Joe's place had changed to a room for reminiscences and remorse, a place to drown one's troubles—or poison them—or to preserve them in alcohol.

He went to see the local moving picture, a piece advertised as being one of the best mystery thrillers since Hitchcock. He found that all of the interesting parts were cut out and that the only thing that remained was a rather disjointed portrayal of a detective finding meaningless clues and ultimately the criminal. There was a suggestion at the end that the detective and the criminal had fought it out, but whether it was with pistols, field pieces, knives, cream puffs or words was left to the imagination. It was also to be assumed that he and the heroine, who went into a partial blackout every time she sat down, finally got acquainted enough to hold hands after the picture.

Channing stormed out of the theatre after seeing the above and finding that the only cartoon had been barred because it showed an innocuous cow without benefit of shorts.

He troubled Joe for a bottle of the best and took to his apartment in disappointment. By eight o'clock in the evening, Don Channing was asleep with all of his clothing on. The bed rolled and refused to stay on an even keel, but Channing found a necktie and tied himself securely in the bed and died off in a beautiful, boiled cloud.

He awoke to the tune of a beautiful hangover. He gulped seven glasses of water and staggered to the shower. Fifteen minutes of iced needles and some coffee brought him part way back to his own, cheerful self. He headed down the hall toward the elevator.

He found a note in his office directing him to appear at a conference in Burbank's office. Groaning in anguish, Don went to the Director's office expecting the worst.

It was bad. In fact, it was enough to drive everyone in the conference to drink. Burbank asked opinions on everything, and then tore the opinions apart with little regard to their validity. He expressed his own opinion many times, which was a disgusted sense of the personnel's inability to do anything of real value.

"Certainly," he stormed, "I know you are operating. But have there been any new developments coming out of your laboratory, Mr. Channing?"

Someone was about to tell Burbank that Channing had a doctor's degree, but Don shook his head.

"We've been working on a lot of small items," said Channing. "I cannot say whether there has been any one big thing that we could point to. As we make developments, we put them into service. Added together, they make quite an honest effort."

"The last one was the coupler machine improvement that permitted better than ten thousand words per minute."

"Up to that time the best wordage was something like eight thousand words," said Burbank. "I think that you have been resting too long on your laurels. Unless you can bring me something big enough to advertise, I shall have to take measures."

"Now you, Mr. Warren," continued Burbank. "You are the man who is supposed to be superintendent of maintenance. May I ask why the outer hull is not painted?"

"Because it would be a waste of paint," said Warren. "Figure out the acreage of a surface of a cylinder three miles long and a mile in diameter. It is almost eleven square miles! Eleven square miles to paint from scaffolding hung from the outside itself."

"A bos'n's chair would be worthless," Warren informed Burbank. "You must remember that to anyone trying to operate on the outer hull, the outer hull is a ceiling and directly overhead.

"Another thing," said Warren, "you paint that hull and you'll run this station by yourself. Why d'ya think we have it shiny?"

"If we paint the hull," persisted Burbank, "it will be more presentable than that nondescript steel color."

"That steel color is as shiny as we could make it," growled Warren. "We want to get rid of as much radiated heat as we can. You slap a coat of any kind of paint on that hull and you'll have plenty of heat in here."

"Don't be an idiot," snapped Warren. "Heating costs, my grandmother's eye. Look, Burbank, did you ever hear of the Uranium Pile? Part of our income comes from refining uranium and plutonium and the preparation of radioisotopes. And—Good Lord, I'm not going to try to explain fission-reacting materials to you; get that first old copy of the Smyth Report and get caught up to date.

"The fact remains," continued Warren, cooling somewhat after displaying Burbank's ignorance, "that we have more power than we know what to do with. We're operating on a safe margin by radiating just a little more than we generate. We make up the rest by the old methods of artificial heating.

"But there have been a lot of times when it became necessary to dissipate a lot of energy for divers reasons and then we've had to shut off the heating. What would happen if we couldn't cool off the damned coffee can? We'd roast to death the first time we got a new employee with a body temperature a degree above normal."

"So I am. And if you persist in your attempt to make this place presentable, you'll find me and my gang outright mutinous! Good day, sir!"

"Take a note, Miss Westland, 'Interplanetary Communications Commission, Terra. Gentlemen: Michael Warren, superintendent of maintenance at Venus Equilateral, has proven to be unreceptive to certain suggestions as to the appearance and/or operation of Venus Equilateral. It is my request that he be replaced immediately. Signed, Francis Burbank, Director.'" He paused to see what effect that message had upon the faces of the men around the table. "Send that by special delivery!"

Johnny Billings opened his mouth to say something, but shut it with a snap. Westland looked up at Burbank, but she said nothing. Arden gave Channing a sly smile, and Channing smiled back. There were grins about the table, too, for everyone recognized the boner. Burbank had just sent a letter from the interworld communications relay station by special delivery mail. It would not get to Terra for better than two weeks; a use of the station's facilities would have the message in the hands of the Commission within the hour.

"That will be all, gentlemen." Burbank smiled smugly. "Our next conference will be next Monday morning!"

"Mr. Channing," chortled the pleasant voice of Arden Westland, "now that the trifling influence of the boss versus secretary taboo is off, will you have the pleasure of buying me a drink?"

"A man isn't supposed to make eyes at his secretary. A gal ain't supposed to seduce her boss. Now that you are no longer Acting Director, and I no longer your stenog, how about some sociability?"

"I never thought that I'd be propositioned by a typewriter jockey," said Channing, "but I'll do it. What time is it? Do we do it openly, or must we sneak over to the apartment and snaffle a snort on the sly?"

"I'm scared to death," Channing informed her. "But if I should fail to defend my honor, we must remember that it is no dishonor to try and fail."

"That sounds like a nice alibi," said Arden with a smile. "Or a come-on. I don't know which. Or, Mr. Channing, am I being told that my advances might not be welcome?"

"We shall see," Channing said. "We'll have to make a careful study of the matter. I cannot make any statements without first making a thorough examination under all sorts of conditions. Here we are. You will precede me through the door, please."

"So that you cannot back out at the last possible moment. Once I get you inside, I'll think about keeping you there!"

"As long as you have some illegal fluid, I'll stay." She tried to leer at Don but failed because she had had all too little experience in leering. "Bring it on!"

"Nope. Here's to the future," proposed Arden. "Those good old days—all they were was old. If you were back in them, you'd still have to have the pleasure of meeting Burbank."

"I need another," said Channing. "Can you imagine that buzzard asking me to invent something big in seven days?"

"Sure. By the same reasoning that he uses to send a letter from Venus Equilateral instead of just slipping it in on the Terra beam. Faulty."

The door opened abruptly and Walt Franks entered. "D'ja hear the latest?" he asked breathlessly.

"No," said Channing. He was reaching for another glass automatically. He poured, and Walt watched the amber fluid creep up the glass, led by a sheet of white foam.

"Then look!" Walt handed Channing an official envelope. It was a regular notice to the effect that there had been eleven failures of service through Venus Equilateral.

"Remember the removal of my jurisdiction over the beam control operators? Well, in the last ten days, Burbank has installed some new features to cut expenses. I think that he hopes to lay off a couple of hundred men."

"He's shortening the dispersion. He intends to cut the power by slamming more of the widespread beam into the receptor. The tighter beam makes aiming more difficult, you know, because at seventy million miles, every time little Joey on Mars swings his toy horseshoe magnet on the end of his string, the beam wabbles. And at seventy million miles, how much wabbling does it take to send a narrow beam clear off the target?"

"The normal dispersion of the beam from Venus is over a thousand miles wide. It gyrates and wabbles through most of that arc. That is why we picked that particular dispersion. If we could have pointed the thing like an arrow, we'd have kept the dispersion down."

"Right. And he's tightened the beam to less than a hundred miles' dispersion. Now, every time a sunspot gets hit amidships with a lady sunspot, the beam goes off on a tangent. We've lost the beam eleven times in a week. That's more times than I've lost it in three years!"

"O.K.," said Channing. "So what? Mastermind is responsible. We'll sit tight and wait for developments. In any display of abilities, we can spike Mr. Burbank. Have another drink?"

"Got any more? If you're out, I've got a couple of cases cached underneath the bed in my apartment."

"I've plenty," said Channing. "And I'll need plenty. I have exactly twenty-two hours left in which to produce something comparable to the telephone, the electric light, the airplane, or the expanding universe! Phooey. Pour me another, Arden."

A knock at the door; a feminine voice interrupted simultaneously. "May I come in?"

It was Walt's secretary. She looked worried. In one hand she waved another letter.

"Worse. Notice that for the last three hours, there have been less than twelve percent of messages relayed!"

"Came out on the Terra beam. It's marked number seventeen, so I guess that sixteen other tries have been made."

"What has Mastermind tried this time?" stormed Channing. He tore out of the room and headed for the Director's office on a dead run. On the way, he hit his shoulder on the door, caromed off the opposite wall, righted himself, and was gone in a flurry of flying feet. Three heads popped out of doors to see who was making the noise.

Channing skidded into Burbank's office on his heels. "What gives?" he snapped. "D'ya realize that we've lost the beam? What have you been doing?"

"It is a minor difficulty," said Burbank calmly. "We will iron it out presently."

"Presently! Our charter doesn't permit interruptions of service of that magnitude. I ask again: What are you doing?"

"You, as electronics engineer, have no right to question me. I repeat, we shall iron out the difficulty presently."

Channing snorted and tore out of Burbank's office. He headed for the Office of Beam Control, turned the corner on one foot, and slammed the door in roughly.

No answer. Channing left the beam office and headed for the master control panels, out near the air lock end of Venus Equilateral. He found Thomas stewing over a complicated piece of apparatus.

"Thought you knew," answered Thomas. "Burbank had the crew install photoelectric mosaic banks on the beam controls. He intends to use the photomosaics to keep Venus, Terra, and Mars on the beam."

"Great Snivelling Scott! They tried that in the last century and tossed it out three days later. Where's the crew now?"

"Get 'em back! Put 'em to work. Turn off those darned photomosaics and use the manual again. We've lost every beam we ever had."

A sarcastic voice came in at this point. "For what reason do you interfere with my improvements?" sneered the voice. "Could it be that you are accepting graft from the employees to keep them on the job by preventing the installation of superior equipment?"

Channing turned on his toe and let Burbank have one. It was a neat job, coming up at the right time and connecting sweetly. Burbank went over on his head.

Charles Thomas grinned. It was not Channing's one-ninety that decided him to comply. He left.

Channing shook Burbank's shoulder. He slapped the man's face. Eyes opened, accusing eyes rendered mute by a very sore jaw, tongue, and throat.

"Now listen," snapped Channing. "Listen to every word! Mosaic directors are useless. Know why? It is because of the lag. At planetary distances, light takes an appreciable time to reach. Your beam wabbles. Your planet swerves out of line because of intervening factors; varying magnetic fields, even the bending of light due to gravitational fields will shake the beam microscopically. But, Burbank, a microscopic discrepancy is all that is needed to bust things wide open. You've got to have experienced men to operate the beam controls. Men who can think. Men who can, from experience, reason that this fluctuation will not last, but will swing back in a few seconds, or that this type of swerving will increase in magnitude for a half-hour, maintain the status, and then return, pass through zero and find the same level on the minus side.

"Since light and centimeter waves are not exactly alike in performance, a field that will swerve one may not affect the other as much. Ergo your photomosaic is useless. The photoelectric mosaic is a brilliant gadget for keeping a plane in a spotlight or for aiming a sixteen-inch gun, but it is worthless for anything over a couple of million miles.

"So I've called the men back to their stations. And don't try anything foolish again without consulting the men who are paid to think!"

Channing got up and left. As he strode down the stairs to the apartment level, he met many of the men who had been laid off. None of them said a word, but all of them wore bright, knowing smiles.

By Monday morning, however, Burbank was himself again. The rebuff given him by Don Channing had worn off and he was sparkling with ideas. He speared Franks with the glitter in his eye and said: "If our beams are always on the center, why is it necessary to use multiplex diversity?"

Franks smiled. "You're mistaken," he told Burbank. "They're not always on the button. They vary. Therefore, we use diversity transmission so that if one beam fails momentarily, one of the other beams will bring the signal in. It is analogous to tying five or six ropes onto a hoisted stone. If one breaks, you have the others."

"Certainly. At several minutes of time-lag in transmission, to try and establish a beam failure of a few seconds' duration is utter foolishness."

"And you disperse the beam to a thousand miles wide to keep the beam centered at any variation?" Burbank shot at Channing.

"Then why don't we disperse the beam to two or three thousand miles and do away with diversity transmission?" asked Burbank triumphantly.

"Ever heard of fading?" asked Channing with a grin. "Your signal comes and goes. Not gyration, it just gets weaker. It fails for want of something to eat, I guess, and takes off after a wandering cosmic ray. At any rate, there are many times per minute that one beam will be right on the nose and yet so weak that our strippers cannot clean it enough to make it usable. Then the diversity system comes in handy. Our coupling detectors automatically select the proper signal channel. It takes the one that is the strongest and subdues the rest within itself."

"It was done in the heyday of radio—1935 or so. Your two channels come in to a common detector. Automatic volume control voltage comes from the single detector and is applied to all channels. This voltage is proper for the strongest channel, but is too high for the ones receiving the weaker signal; blocking them by rendering them insensitive. When the strong channel fades and the weak channel rises, the detector follows down until the two signal channels are equal and then it rises with the stronger channel."

"It is like the weather, according to Mark Twain," smiled Channing. "'Everybody talks about it, but nobody does anything about it.' About all we've learned is that we can cuss it out and it doesn't cuss back."

"If you'll pardon me, it has been tried. The first installation at Venus Equilateral was made that way. It didn't work, though we used more power than all of our diversity transmitters together. Sorry."

"Nothing. I've been more than busy investigating the trouble we've had in keeping the beams centered."

Burbank said nothing. He was stopped. He hoped that the secret of his failure was not generally known, but he knew at the same time that when three hundred men are aware of something interesting, some of them will see to it that all the others involved will surely know. He looked at the faces of the men around the table and saw suppressed mirth in every one of them. Burbank writhed in inward anger. He was a good poker player. He didn't show it at all.

He then went on to other problems. He ironed some out, others he shelved for the time being. Burbank was a good business man. But like so many other businessmen, Burbank had the firm conviction that if he had the time to spare and at the same time was free of the worries and paper work of his position, he could step into the laboratory and show the engineers how to make things hum. He was infuriated every time he saw one of the engineering staff sitting with hands behind head, lost in a gazy, unreal land of deep thought. Though he knew better, he was often tempted to raise hell because the man was obviously loafing.

But give him credit. He could handle business angles to perfection. In spite of his tangle over the beam control, he had rebounded excellently and had ironed out all of the complaints that had poured in. Ironed it out to the satisfaction of the injured party as well as the Interplanetary Communications Commission, who were interested in anything that cost money.

He dismissed the conference and went to thinking. And he assumed the same pose that infuriated him in other men under him; hands behind head, feet upon desk.

The moving picture theater was dark. The hero reached longing arms to the heroine, and there was a sort of magnetic attraction. They approached one another. But the spark misfired. It was blacked out with a nice slice of utter blackness that came from the screen and spread its lightlessness all over the theater. In the ensuing darkness, there were several osculations that were more personal and more satisfying than the censored clinch. The lights flashed on and several male heads moved back hastily. Female lips smiled happily. Some of them parted in speech.

"Shut up, Arden," snapped the man. "People will think that I've been kissing you."

"If someone else was taking advantage of the situation," she said, "you got gypped. I thought I was kissing you and I cooked with gas!"

"I liked it. I merely wondered, if you'd worked it on other men, what there was about you that kept you single."

"Let me outta here! I get the implication. I am the first bird that hasn't died, hey?" He yawned luxuriously.

"Can't be either," he said. "Come on, let's break a bottle of beer open. I'm dry!"

"What have you been doing?" asked Arden. "Haven't seen you for a couple of days."

"Nothing worth mentioning. Had an idea a couple of days ago and went to work on it."

"Then I don't see why you should be ill. I can explain my headache away by attributing it to eyestrain. Since Billyboy came here, and censored the movies to the bone, the darned things flicker like anything. But eyestrain doesn't create an autointoxication. So, my fine fellow, what have you been drinking?"

"Nothing that I haven't been drinking since I first took to my second bottlehood some years ago."

"You wouldn't be suffering from a hangover from that hangover you had a couple of weeks ago?"

"Nope. I swore off. Never again will I try to drink a whole quart of Two Moons in one evening. It got me."

Don Channing said nothing. He recalled, all too vividly, the rolling of the tummy that ensued after that session with the only fighter that hadn't yet been beaten: Old John Barleycorn.

"How are you coming on with Burbank?" asked Arden. "I haven't heard a rave for—well, ever since Monday morning's conference. Three days without a nasty dig at Our Boss. That's a record."

"Give the devil his due. He's been more than busy placating irate citizens. That last debacle with the beam control gave him a real Moscow winter. His reforms came to a stop whilst he entrenched. But he's been doing an excellent job of squirming out from under. Of course, it has been helped by the fact that even though the service was rotten for a few hours, the customers couldn't rush out to some other agency to get communications with the other planets."

Channing opened the door to his apartment and Arden went in. Channing followed, and then stopped cold.

"Have you noticed?" he asked. "It smells like the inside of a chicken coop in here!"

Arden sniffed. "It does sort of remind me of something that died and couldn't get out of its skin." Arden smiled. "I'll hold my breath. Any sacrifice for a drink."

"That isn't the point. This is purified air. It should be as sweet as a baby's breath."

"It wasn't cow-juice. What I've been trying to put over is that the air doesn't seem to have been changed in here for nine weeks."

Channing went to the ventilator and lit a match. The flame bent over, flickered, and went out.

"Air intake is O.K.," he said. "Maybe it is I. Bring on that bottle, Channing; don't keep the lady waiting."

He yawned again, deeply and jaw-stretchingly. Arden yawned, too, and the thought of both of them stretching their jaws to the breaking-off point made both of them laugh foolishly.

"Arden, I'm going to break one bottle of beer with you, after which I'm going to take you home, kiss you good night, and toss you into your own apartment. Then I'm coming back here and I'm going to hit the hay!"

Arden took a long, deep breath. "I'll buy that," she said. "And tonight, it wouldn't take much persuasion to induce me to snooze right here in this chair!"

"Oh, fine," cheered Don. "That would fix me up swell with the neighbors. I'm not going to get shotgunned into anything like that!"

"From the look in your eye," said Channing, "I'd say that you were just about to do that very thing. I was merely trying to dissolve any ideas that you might have."

"Don't bother," she said pettishly. "I haven't any ideas. I'm as free as you are, and I intend to stay that way!"

Channing stood up. "The next thing we know, we'll be fighting," he observed. "Stand up, Arden. Shake."

Arden stood up, shook herself, and then looked at Channing with a strange light in her eyes. "I feel sort of dizzy," she admitted. "And everything irritates me."

She passed a hand over her eyes wearily. Then, with a visible effort, she straightened. She seemed to throw off her momentary ill feeling instantly. She smiled at Channing and was her normal self in less than a minute.

"When Channing would prefer snoozing to boozing he is sick," she said. "Come on, fellow, take me home."

Slowly they walked down the long hallway. They said nothing. Arm in arm they went, and when they reached Arden's door, their good-night kiss lacked enthusiasm. "See you in the morning," said Don.

Arden looked at him. "That was a little flat. We'll try it again—tomorrow or next week."

Don Channing's sleep was broken by dreams. He was warm. His dreams depicted him in a humid, airless chamber, and he was forced to breathe that same stale air again and again. He awoke in a hot sweat, weak and feeling—lousy!

He dressed carelessly. He shaved hit-or-miss. His morning coffee tasted flat and sour. He left the apartment in a bad mood, and bumped into Arden at the corner of the hall.

"Hello," she said. "I feel rotten. But you have improved. Or is that passionate breathing just a lack of fresh air?"

"Hell! That's it!" he said. He snapped up his wrist watch, which was equipped with a stop-watch hand. He looked about, and finding a man sitting on a bench, apparently taking it easy while waiting for someone, Channing clicked the sweep hand into gear. He started to count the man's respiration.

"What gives?" asked Arden, "What's 'It'? Why are you so excited? Did I say something?"

"You did," said Channing after fifteen seconds. "That bird's respiration is better than fifty! This whole place is filled to the gills with carbon dioxide. Come on, Arden, let's get going!"

Channing led the girl by several yards by the time that they were within sight of the elevator. He waited for her, and then sent the car upward at a full throttle. Minutes passed, and they could feel that stomach-rising sensation that comes when gravity is lessened. Arden clasped her hands over her middle and hugged. She squirmed and giggled.

The car came to a stop with a slowing effect. A normal braking stop would have catapulted them against the ceiling. "Come on," he grinned at her, "here's where we make time!"

Channing looked up at the little flight of stairs that led to the innermost level. He winked at Arden and jumped. He passed up through the opening easily. "Jump," he commanded. "Don't use the stairs."

Arden jumped. She sailed upward, and as she passed through the opening, Channing caught her by one arm and stopped her flight. "At that speed you'd go right on across," he said.

She looked up, and there about two hundred feet overhead she could see the opposite wall.

Channing snapped on the lights. They were in a room two hundred feet in diameter and three hundred feet long. "We're at the center of the station," Channing informed her. "Beyond that bulkhead is the air lock. On the other side of the other bulkhead, we have the air plant, the storage spaces, and several rooms of machinery."

"Come on," he said. He took her by the hand and with a kick he propelled himself along on a long, curving course to the opposite side of the inner cylinder. He gained the opposite bulkhead as well.

"Now, that's what I call traveling," said Arden. "But my tummy goes whoosh, whoosh every time we cross the center."

Channing operated a heavy door. They went in through rooms full of machinery and into rooms stacked to the center with boxes; stacked from the wall to the center and then packed with springs. Near the axis of the cylinder, things weighed so little that packing was necessary to keep them from floating around.

"High in oxygen," said he. "The CO₂, drops to the bottom, being heavier. Then, too, the air is thinner up here because centrifugal force swings the whole out to the rim. Out there we are so used to 'down' that here, a half mile above—or to the center, rather—we have trouble in saying, technically, what we mean. Watch!"

He left Arden standing and walked rapidly around the inside of the cylinder. Soon he was standing on the steel plates directly over her head. She looked up, and shook her head.

"I know why," she called, "but it still makes me dizzy. Come down from up there or I'll be sick."

Channing made a neat dive from his position above her head. He did it merely by jumping upward from his place toward her place, apparently hanging head down from the ceiling. He turned a neat flip-flop in the air and landed easily beside her. Immediately, for both of them, things became right-side-up again.

Channing opened the door to the room marked: "Air Plant." He stepped in, snapped on the lights, and gasped in amazement.

"Hell!" he groaned. The place was empty. Completely empty. Absolutely, and irrevocably vacant. Oh, there was some dirt on the floor and some trash in the corners, and a trail of scratches on the floor to show that the life giving air plant had been removed, hunk by hunk, out through another door at the far end of the room.

"Whoa, Tillie!" screamed Don. "We've been stabbed! Arden, get on the type and have ... no, wait a minute until we find out a few more things about this!"

They made record time back to the office level. They found Burbank in his office, leaning back, and talking to someone on the phone.

Channing tried to interrupt, but Burbank removed his nose from the telephone long enough to snarl, "Can't you see I'm busy? Have you no manners or respect?"

Channing, fuming inside, swore inwardly. He sat down with a show of being calm and folded his hands over his abdomen like the famed statue of Buddha. Arden looked at him, and for all the trouble they were in, she couldn't help giggling. Channing, tall, lanky, and strong, looked as little as possible like the popular, pudgy figure of the Sitting Buddha.

"There must be more than one. We couldn't live if there weren't," said the Director.

"I tell you, there must be another. Why, I went into the one up at the axis day before yesterday and found that instead of a bunch of machinery, running smoothly, purifying air, and sending it out to the various parts of the station, all there was was a veritable jungle of weeds. Those weeds, Mr. Channing, looked as though they must have been put in there years ago. Now, where did the air-purifying machinery go?"

Channing listened to the latter half of Burbank's speech with his chin at half-mast. He looked as though a feather would knock him clear across the office.

"I had some workmen clear the weeds out. I intend to replace the air machinery as soon as I can get some new material sent from Terra."

Channing managed to blink. It was an effort. "You had workmen toss the weeds out—" he repeated dully. "The weeds—"

There was silence for a minute, Burbank studied the man in the chair as though Channing were a piece of statuary. Channing was just as motionless. "Channing, man, what ails you—" began Burbank. The sound of Burbank's voice aroused Channing from his shocked condition.

Channing leaped to his feet. He landed on his heels, spun, and snapped at Arden: "Get on the type. Have 'em slap as many oxy-drums on the fastest ship as they've got! Get 'em here at full throttle. Tell 'em to load up the pilot and crew with gravanol and not to spare the horsepower! Scram!"

"What better purifying machine is there than a plot of grass?" shouted Channing. "Weeds, grass, flowers, trees, alfalfa, wheat, or anything that grows and uses chlorophyll. We breathe oxygen, exhale CO₂. Plants inhale CO₂, and exude oxygen. An air plant means just that. It is a specialized type of Martian sawgrass that is more efficient than anything else in the system for inhaling dead air and revitalizing it. And you've tossed the weeds out!" Channing snorted in anger. "We've spent years getting that plant so that it will grow just right. It got so good that the CO₂ detectors weren't even needed. The balance was so adjusted that they haven't even been turned on for three or four years. They were just another source of unnecessary expense. Why, save for a monthly inspection, that room isn't even opened, so efficient is the Martian sawgrass. We, Burbank, are losing oxygen!"

"Well, you know now. Get on your horse and do something. At least, Burbank, stay out of my way while I do something."

Channing left the office of the Director and headed for the chem lab. "How much potassium chlorate, nitrate, sulphate, and other oxygen-bearing compounds have you?" he asked. "That includes mercuric oxide, spare water, or anything else that will give us oxygen if broken down."

There was a ten-minute wait until the members of the chem lab took a hurried inventory.

"Good," said Channing. "Start breaking it down. Collect all the oxygen you can in containers. This is the business! It has priority! Anything, no matter how valuable, must be scrapped if it can facilitate the gathering of oxygen. God knows, there isn't by half enough—not even a tenth. But try, anyway."

Channing headed out of the chemistry laboratory and into the electronics lab. "Jimmie," he shouted, "get a couple of stone jars and get an electrolysis outfit running. Fling the hydrogen out of a convenient outlet into space and collect the oxygen. Water, I mean. Use tap water, right out of the faucet."

"Jimmie, if we don't breathe, what chance have we to go on drinking? I'll tell you when to stop."

"And look. As soon as you get that running, set up a CO₂ indicator and let me know the percentage at the end of each hour! Get me?"

"It isn't functioning," said Channing shortly. He left the puzzled Jimmie and headed for the beam-control room. Jimmie continued to wonder about the air plant. How in the devil could an air plant cease functioning unless it were—dead! Jimmie stopped wondering and began to operate on his electrolysis set-up furiously.

Channing found the men in the beam-control room worried and ill at ease. The fine co-ordination that made them expert in their line was ebbing. The nervous work demanded perfect motor control, excellent perception, and a fine power of reasoning. The perceptible lack of oxygen at this high level was taking its toll already.

"Look, fellows, we're in a mess. Until further notice, take five-minute shifts. We've got about thirty hours to go. If the going gets tough, drop it to three-minute shifts. But, fellows, keep those beams centered until you drop!"

"We'll keep 'em going if we have to call our wives up here to run 'em for us," said one man. "What's up?"

"Air plant's sour. Losing oxy. Got a shipload coming out from Terra, be here in thirty hours. But upon you fellows will rest the responsibility of keeping us in touch with the rest of the system. If you fail, we could call for help until hell freezes us all in—and no one would hear us!"

"We'll keep 'em rolling," said a little fellow who had to sit on a tall stool to get even with the controls.

Channing looked out of the big, faceted plexiglass dome that covered the entire end of the Venus Equilateral Station. "Here messages go in and out," he mused. "The other end brings us things that take our breath away."

Channing was referring to the big air lock at the other end of the station, three miles away, right through the center.

At the center of the dome, there was a sighting 'scope. It kept Polaris on a marked circle, keeping the station exactly even with the Terrestrial North. About the periphery of the dome, looking out across space, the beam-control operators were sitting, each with a hundred-foot parabolic reflector below his position, outside the dome, and under the rim of the transparent howl. These reflectors shot the interworld signals across space in tight beams, and the men, half the time anticipating the vagaries of space-warp, kept them centered on the proper, shining speck in that field of stars.

Above his head the stars twinkled. Puny man, setting his will against the monstrous void. Puny man, dependent upon atmosphere. "'Nature abhors a vacuum,' said Torricelli," groaned Channing. "Nuts! If nature abhorred a vacuum, why did she make so much of it?"

Arden Westland entered the apartment without knocking. "I'd give my right arm up to here for a cigarette," she said, marking above the elbow with the other hand.

"Not as much as I'd like to do," said Channing. "I can't help much. We've got most of the place stopped off with the air-tight doors. We've been electrolyzing water, baking KClO₃ and everything else we can get oxy out of. I've a crew of men trying to absorb the CO₂ content and we are losing. Of course, I've known all along that we couldn't support the station on the meager supplies we have on hand. But we'll win in the end. Our microcosmic world is getting a shot in the arm in a few hours that will re-set the balance."

"This station is well balanced. There are enough people here and enough space to make a little world of our own. We can establish a balance that is pretty darned close to perfect. The imperfections are taken care of by influxes of supplies from the system. Until Burbank upset the balance, we could go on forever, utilizing natural purification of air and water. We grow a few vegetables and have some meat critters to give milk and steak. The energy to operate Venus Equilateral is supplied from the uranium pile. Atomic power, if you please. Why should we burden ourselves with a lot of cubic feet of supplies that would take up room necessary to maintain our balance? We are not in bad shape. We'll live, though we'll all be a bunch of tired, irritable people who yawn in one another's faces."

"We'll establish the balance. Then we'll settle down again. We can take up where we left off," said Don.

"Not quite. Venus Equilateral has been seared by fire. We'll be tougher and less tolerant of outsiders. If we were a closed corporation before, we'll be tighter than a vacuum-packed coffee can afterwards. And the first bird that cracks us will get hissed at."

Three superliners hove into sight at the end of thirty-one hours. They circled the station, signaling by helio. They approached the air lock end of the station and made contact. The air lock was opened and space-suited figures swarmed over the South End Landing Stage. A stream of big oxygen tanks was brought into the air lock, admitted, and taken to the last bulwark of huddled people on the fourth level.

From one of the ships there came a horde of men carrying huge square trays of dirt and green, growing sawgrass.

For six hours, Venus Equilateral was the scene of wild, furious activity. The dead air was blown out of bad areas, and the hissing of oxygen tanks was heard in every room. Gradually the people left the fourth level and returned to their rightful places. The station rang with laughter once more, and business, stopped short for want of breath, took a deep lungful of fresh air and went back to work.

The superliners left. But not without taking a souvenir. Francis Burbank went with them. His removal notice was on the first ship, and Don Channing's appointment as Director of Venus Equilateral was on the second.

Happily he entered the Director's office once more. He carried with him all the things that he had removed just a few short weeks before. This time he was coming to stay.

"Yop," he grinned at her. "Open file B, will you, and break out a container of my favorite beverage?"

There came a shout of glee. "Break out four glasses," she was told from behind. It was Walt Franks and Joe.

It was Arden that proposed the toast. "Here's to a closed corporation," she said. They drank on that.

She went over beside Don and took his arm. "You see?" she said, looking up into his eyes. "We aren't the same. Things have changed since Burbank came, and went. Haven't they?"

"They have," laughed Channing. "And now that you are my secretary, it is no longer proper for you to shine up to me like that. People will talk."

Channing answered, "It is considered highly improper for a secretary to make passes at her boss. Think of what people will say; think of his wife and kids."

"No man can use that tone of voice on me!" stormed Arden with a glint in her eye. "I resign! You can't call me a secretary!"

Arden relaxed into the crook of Channing's arm. She winked at Walt and Joe. "Me—," she said, "I've been promoted!"

Interlude:

Maintaining Communications through the worst of interference was a type of problem in which dire necessity demanded a solution. Often there are other problems of less demanding nature. These are sometimes called "projects" because they may be desirable but are not born of dire necessity.

Barring interference, the problem of keeping communication with another planet across a hundred million miles of interplanetary space is partially solved by the fact that you can see your target! Keeping the cross-hairs in a telescope properly centered is a technical job more arduous than difficult.

But seeing a spacecraft is another problem. Consider the relative sizes of spacecraft and planet. Where Terra is eight thousand miles in diameter, the largest of spacecraft is eight hundred feet long. Reduced to a common denominator and a simple ratio, it reads that the earth is 50,000 times as large as the largest spacecraft. Now go outside and take a look at Venus. At normal distances, it is a mote in the sky. Yet Venus is only slightly smaller than the earth. Reduce Venus by fifty thousand times, and no astronomer would ever suspect its existence.

Then take the invisible mote and place it in a volume of 1,000,000,000,000,000,000 cubic miles and he who found the needle in a haystack is a piker by comparison.

It could have been lives at stake that drove the job out of the "project" class and into the "necessity" stage. The fact that it was ebb and flow of a mundane thing like money may lower the quality of glamor.

But there it was—a problem that cried out for a solution; a man who was willing to pay for the attempt; and a group of technicians more than happy to tackle the job.

CALLING THE EMPRESS

The chart in the terminal building at Canalopsis Spaceport, Mars, was a huge thing that was the focus of all eyes. It occupied a thirty-by-thirty space in the center of one wall, and it had a far-flung iron railing about it to keep the people from crowding it too close, thus shutting off the view. It was a popular display, for it helped to drive home the fact that space travel was different from anything else. People were aware that their lives had been built upon going from one fixed place to another place, equally immobile. But on interplanet travel, one left a moving planet for another planet, moving at a different velocity. You found that the shortest distance was not a straight line but a space curve involving higher mathematics.

The courses being traveled at the time were marked, and those that would be traversed in the very near future were drawn upon the chart, too; all appropriately labeled. At a glance, one could see that in fifty minutes and seventeen seconds the Empress of Kolain would take off from Mars, which was the red disk on the right, and she would travel along the curve so marked to Venus, which was almost one hundred and sixty degrees clockwise around the Sun. People were glad of the chance to go on this trip because the Venus Equilateral Relay Station would come within a telescope's sight on the way.

The Empress of Kolain would slide into Venus on the day side; and a few hours later she would lift again to head for Terra, a few degrees ahead of Venus and about thirty million miles away.

Precisely on the zero-zero, the Empress of Kolain lifted upward on four tenuous pillars of dull-red glow and drove a hole in the sky. The glow was almost lost in the bright sunshine, and soon it died. The Empress of Kolain became a little world in itself, and would so remain until it dropped onto the ground at Venus, almost two hundred million miles away.

Driving upward, the Empress of Kolain could not have been out of the thin Martian atmosphere when a warning bell rang in the telephone and telespace office at the terminal. The bell caught official ears, and all work was stopped as the personnel of the communications office ran to the machine to see what was so important that the "immediate attention" signal was rung.

Impatiently the operator waited for the tape to come clicking from the machine. It came, letter by letter, click by click, at fifty words per minute. The operator tore the strip from the machine and read aloud: "Hold Empress of Kolain. Reroute to Terra direct. Will be quarantined at Venus. Whole planet in epidemic of Venusian Fever."

"Snap answer," growled the clerk. "Tell 'em: 'Too little and too late. Empress of Kolain left thirty seconds before warning bell. What do we do now?'"

The operator's fingers clicked madly over the keyboard. Across space went the signal, across the void to the Relay Station. It ran through the Station's mechanism and went darting to Terra. It clicked out as sent in the offices of Interplanet Transport. A vice president read the message and swore roundly. He swore in three Terran languages, in the language of the Venusians, and even managed to visualize a few choice remarks from the Martian Pictographs that were engraved on the Temples of Canalopsis.

"Miss Deane," he yelled at the top of his voice. "Take a message! Shoot a line to Channing on Venus Equilateral. Tell him: 'Empress of Kolain on way to Venus. Must be contacted and rerouted to Terra direct. Million dollars' worth of Martian Line Moss aboard; will perish under quarantine. Spare no expense.' Sign that 'Keg Johnson, Interplanet.'"

More minutes of light-fast communication. Out of Terra to Luna, across space to Venus Equilateral. The machines clicked and tape cleared away from the slot. It was pasted neatly on a sheet of official paper, stamped rush, and put in a pneumatic tube.

As Don Channing began to read the message, Williams on Mars was chewing worriedly on his fourth fingernail, and Vice President Keg Johnson was working on his second. But Williams had a head start and therefore would finish first. Both men knew that nothing more could be done. If Channing couldn't do it, nobody could.

Channing finished the 'gram and swore. It was a good-natured swear-word, far from downright vilification, though it did consign certain items to the nether regions. He punched a button with some relish, and a rather good-looking woman entered. She smiled at him with more intimacy than a secretary should, and sat down.

Arden Westland smiled. "You might have done that yourself," she told him. She reached for the call button with her left hand, and the diamond on her finger glinted like a pilot light.

"Baloney," said Arden. "You just wait until next October. I'll be in your hair all the time then."

"By then I may be tired of you," said Channing with a smile. "But until then, take it or leave it." His face grew serious, and he tossed the message across the table to her. "What do you think of that?"

"It'll cost plenty. I don't know whether we can contact a ship in space. It hasn't been done to date, you know, except for short distances."

The door opened without a knock and Walt Franks walked in. "Billing and cooing?" he asked. "Why do you two need an audience?"

"Walt, what are the chances of hooking up with the Empress of Kolain, which is en route from Mars to Venus?"

"About equal to a snowball—you know where," said Franks looking slyly at Arden.

"Boy, this is a job I wouldn't want my life to depend on. In the first place, we can't beam a transmitter at them if we can't see 'em. And in the second place, if we did, they couldn't receive us."

"We can get a good idea of where they are and how they're going," said Channing. "That is common knowledge."

"Astronomy is an exact science," chanted Franks. "But by the time we figure out just where the Empress of Kolain is with respect to us at any given instant we'll all be old men with gray beards. She's crossing toward us on a skew curve—and we'll have to beam it past Sol. It won't be easy, Don. And then if we do find them, what do we do about it?"

"Let's find them first and then work out a means of contacting them afterwards."

Franks fell backward into a chair. Don turned to the girl and asked: "Are you kidding?"

"No. I'm just ignorant. What is so hard about it? We shoot beams across a couple of hundred million miles of space like nothing and maintain communications at any cost. What should be so hard about contacting a ship?"

"In the first place, we can see a planet, and they can see us, so they can hold their beams. A spaceship might be able to see us, but they couldn't hold a beam on us because of the side sway. We couldn't see them until they are right upon us and so we could not hope to hold a beam on them. Spaceships might broadcast, but you have no idea what the square law of radiated power will do to a broadcast signal when millions upon millions of miles are counted in. A half million watts on any planet will not quite cover the planet as a service area on broadcast frequencies. But there's a lot of difference between covering a few stinking miles of planet and a volume the size of the Inner Solar System. So they don't try it. A spaceship may as well be on Rigel as far as contacting her in space goes.

"We might beam a wide-dispersion affair at them," continued Channing. "But it would be pretty thin by the time it got there. And, having no equipment, they couldn't hear us."

"May we amend that?" asked Franks. "They are equipped with radio. But the things are used only in landing operations where the distance is measured in miles, not Astronomical Units."

"O.K.," smiled Channing. "It's turned off during flight and we may consider the equipment as being non-existent."

"And, according to the chart, we've got to contact them before the turnabout," offered Arden. "They must have time to deflect their course to Terra."

"You think of the nicest complications," said Channing. "I was just about to hope that we could flash them, or grab at 'em with a skeeter. But we can't wait until they pass us."

"That will be the last hope," admitted Franks. "But say! Did any bright soul think of shooting a fast ship after them from Canalopsis?"

"Sure. The answer is the same as Simple Simon's answer to the Pieman: 'Alas, they haven't any!'"

"No use asking why," growled Franks. "O.K., Don, we'll after 'em. I'll have the crew set up a couple of mass detectors at either end of the station. We'll triangulate, and calculate, and hope to hit the right correction factor. We'll find them and keep them in line. You figure out a means of contacting them, huh?"

"What do you want us to do? Get down on the floor and chew the rug? You know us better than that. If we can find the answer to contacting a spaceship in flight, we'll add another flower to our flag. But we can't do it by clawing through the first edition of Henney's 'Handbook of Radio Engineering.' It will be done by the seat of our pants, if at all; a pair of side-cutters, and a spool of wire, a hunk of string and a lump of solder, a—"

"Leave Kipling out of this. He didn't have to cover the entire Solar System. Let's get cooking."

Don and Walt left the office just a trifle on the fast side. Arden looked after them, out through the open door, shaking her head until she remembered something that she could do. She smiled and went to her typewriter, and pounded out a message back to Keg Johnson at Interplanet. It read:

Unknowing of the storm, the Empress of Kolain sped silently through the void, accelerating constantly at one G. Hour after hour she was adding to her velocity, building it up to a speed that would make the trip in days, and not weeks. Her drivers flared dull red no more, for there was no atmosphere for the ionic stream to excite. Her few portholes sparkled with light, but they were nothing in comparison to the starry curtain of the background.

Her hull was of a neutral color, and though the sun glanced from her metal flanks, a reflection from a convex side is not productive of a beam of light. It spreads according to the degree of convexity and is lost.

What constitutes an apparent absence? The answer to that question is the example of a ship in space flight. The Empress of Kolain did not radiate anything detectable in the electromagnetic scale from ultralong waves to ultra-high frequencies; nothing at all that could be detected at any distance beyond a few thousand miles. The sweep of her meteor-spotting equipment would pass a spot in micro-micro-seconds at a hundred miles; at the distance from Venus Equilateral the sweep of the beam would be so fleeting that the best equipment ever known or made would have no time to react, thus missing the signal.

Theorists claim a thing unexistent if it cannot be detected. The Empress of Kolain was invisible. It was undetectable to radio waves. It was in space, so no physical wave could be transmitted to be depicted as sound. Its mass was inconsiderable. Its size as cosmic sizes go was comparatively sub-microscopic, and therefore it would occult few, if any, stars. Therefore, to all intents and purposes, the Empress of Kolain was non-existent, and would remain in that state of material-non-being until it came to life again upon its landing at Venus.

Yet the Empress of Kolain existed in the minds of the men who were to find her. Like the shot unseen, fired from a distant cannon, the Empress of Kolain was coming at them with ever-mounting velocity, its unseen course a theoretical curve.

And the ship, like the projectile, would land if the men who knew of her failed in their purpose.

Don Channing and Walt Franks found their man in the combined dining room and bar—the only one in sixty million miles. They surrounded him, ordered a sandwich and beer, and began to tell him their troubles.

Charles Thomas listened for about three minutes. "Boy," he grinned, "being up in that shiny, plush-lined office has sure done plenty to your think-tank, Don."

Channing stopped talking. "Proceed," he said. "In what way has my perspective been warped?"

"You talk like Burbank," said Thomas, mentioning a sore spot of some months past. "You think a mass detector would work at this distance? Nuts, fellow. It might, if there were nothing else in the place to interfere. But you want to shoot out near Mars. Mars is on the other side of the Sun—and Evening Star to anyone on Terra. You want us to shoot a slap-happy beam like a mass detector out past Sol; and then a hundred and forty million miles beyond in the faint hope that you can triangulate upon a little mite of matter; a stinking six hundred-odd feet of aluminum hull mostly filled with air and some machinery and so on. Brother, what do you think all the rest of the planets will do to your piddling little beam? Retract, or perhaps abrogate the law of universal gravitation?"

"Forget it," said Thomas. "The only thing that mass detectors are any good for is to conjure up beautiful bubble dreams, which anyone who knows about 'em can break with the cold point of icy logic."

"Darned if I know. We might flash 'em with a big mirror—if we had a big mirror and they weren't heading into the Sun."

"Let's see," said Franks, making tabulations on the tablecloth. "They're a couple of hundred million miles away. In order that your mirror present a recognizable disk, it should be about twice the diameter of Venus as seen from Terra. That's eight thousand miles in—at the least visibility—say, eighty million or a thousand-to-one ratio. The Empress of Kolain is heading at us from some two hundred million miles, so at a thousand-to-one ratio our mirror would have to be twenty thousand miles across. Some mirror!"

Don tipped Walt's beer over the edge of the table, and while the other man was busy mopping up and muttering unprintables, Don said to Thomas: "This is serious and it isn't. Nobody's going to lose their skin if we don't, but a problem has been put to us and we're going to crack it if we have to skin our teeth to do it."

"Sure. Within a couple of hundred thousand miles we can. That isn't close enough."

Silence fell for a moment. It was broken by Arden, who came in waving a telegram. She sat down and appropriated Channing's glass, which had not been touched. Don opened the sheet and read: "Have received confirmation of your effort. I repeat, spare no expense!" It was signed: "Keg Johnson, Interplanet."

"Sure," agreed Don. "But at the same time we're stumped. Should we be doing anything?"

"Anything, I should think, would be better than what you're doing at present. Or does that dinner-and-beer come under 'expenses'?"

Arden stood up, tossed Channing's napkin at him, and started toward the door. Channing watched her go, his hand making motions on the tablecloth. His eyes fell to the table and he took Franks' pencil and drew a long curve from a spot of gravy on one side of the table to a touch of coffee stain on the other. The curve went through a bit of grape jelly near the first stain.

"That spot of gravy," explained Don, "is Mars. The jelly is the Empress of Kolain. Coffee stain is Venus, and up here by this cigarette burn is Venus Equilateral. Get me?"

"Now it would be the job for seventeen astronomers for nine weeks to predict the movements of this jelly spot with respect to the usual astral standards. But, fellows, we know the acceleration of the Empress of Kolain, and we know her position with respect to Mars at the instant of take-off. We can correct for Mars' advance along her—or his—orbit. We can figure the position of the Empress of Kolain from her angular distance from Mars! That's the only thing we need know. We don't give a ten-dollar damn about her true position."

Channing began to write equations on the tablecloth. "You see, they aren't moving so fast in respect to us. The course is foreshortened as they are coming almost in line with Venus Equilateral, curving outward and away from the Sun. Her course, as we see it from the station here, will be a long radius-upward curve, slightly on the parabolic side. Like all long-range cruises the Empress of Kolain will hoist herself slightly above the plane of the ecliptic to avoid the swarm of meteors that follow about the Sun in the same plane as the planets, lifting the highest at the point of greatest velocity.

"I get it," said Franks. "We get the best beam controller we have to keep the planet on the cross hairs. We apply a spiral cam to advance the beam along the orbit. Right?"

"Right." Don sketched a conical section on the tablecloth and added dimensions. He checked his dimensions against the long string of equations, and nodded. "We'll drive this cockeyed-looking cam with an isochronic clock, and then squirt a beam out there. Thank the Lord for the way our beam transmitters work."

"Sure," grinned Don. "There's plenty of radar operating at our transmitting frequencies or near by. So far, no one has ever tried to radar anything as small as a spacecraft at that distance, though getting a radar signal from a planet is duck soup. Yet," he reflected cheerfully, "there are a couple of things we have handy out here, and one of them is a plethora of power output. We can soup up one of our beam transmitters and use it with a tightened beam to get a radar fix off of the Empress of Kolain."

"Then we will have left the small end, which I'll give to you, Walt, so that you can have part of the credit."

Walt shook his head. "The easy part," he said uncheerfully. "By which you mean the manner in which we contact them and make them listen to us?"

"Clear up this mess so we can make the cam. This drawing will do, just grab the tablecloth."

Joe, the operator of Venus Equilateral's one and only establishment for the benefit of the stomach, came up as the three men began to move their glasses and dishes over to an empty table. "What makes with the tablecloth?" he asked. "Want a piece of carbon paper and another tablecloth?"

"We lose lots of tablecloths that way," said Joe. "It's tough, running a restaurant on Venus Equilateral. I tried using paper ones once, but that didn't work. I had 'em printed but when the solar system was on 'em, you fellows drew schematic diagrams for a new coupler circuit. I put all kinds of radio circuits on them, and the gang drew plans for antenna arrays. I gave up and put pads of paper on each table, and the boys used them to make folded paper airplanes and they shot them all over the place. Why don't you guys grow up?"

"Cheer up, Joe. But if this tablecloth won't run through the blueprint machine, we'll squawk!"

Joe looked downcast, and Franks hurried to explain: "It isn't that bad, Joe. We won't try it. We just want to have these figures so we won't have to run through the math again. We'll return the cloth."

"Yeah," said Joe at their retreating figures. "And for the rest of its usefulness it will be full of curves, drawings, and a complete set of astrogating equations." He shrugged his shoulders and went for a new tablecloth.

Don, Walt and Chuck took their improvised drawing to the machine shop, where they put it in the hands of the master mechanic.

"This thing has a top requirement," Don told him. "Make it as quick as you can."

Master Mechanic Warren took the cloth and said: "You forgot the note. You know, 'Work to dimensions shown, do not scale this drawing.' Lord, Don, this silly looking cam will take a man about six hours to do. It'll have to be right on the button all over, no tolerance. I'll have to cut it to the 'T' and then lap it smooth with polishing compound. Then what'll you test it on?"

"Anything you say. It'll only be used once. Anything of sufficient hardness for a single usage will do."

"I'll use brass then. Or free-cutting steel may be better. If you make it soft you have the chance of cutting too much off with your lapping compound. We'll take care of it, Don. The rest of this stuff isn't too hard. Your framework and so on can be whittled out and pasted together from standard girders, right?"

"Sure. Plaster them together any way you can. And we don't want them painted. As long as she works, phooey to the looks."

"Fine," said Warren. "I'll have the whole business installed in the Beam Control Room in nine hours. Complete and ready to work."

"Absolutely. After we cut and polish that screwball cam, we'll have to check it, and then you'll have to check it. Then the silly thing will have to be installed and its concentricity must be checked to the last wave length of cadmium light. That'll take us a couple of hours, I bet. The rest of the works will be ready, checked, and waiting for the ding-busted cam."

"Yeah," agreed Franks. "Then we'll have to get up there with our works and put the electricals on the mechanicals. My guess, Don, is a good, healthy twelve hours before we can begin to squirt our signal."

Twelve hours is not much in the life of a man; it is less in the life of a planet. The Terran Standard of Gravity is so small that it is expressed in feet per second. But when the two are coupled together as a measure of travel, and the standard Terran G is applied for twelve hours steady, it builds up to almost three hundred miles per second, and by the end of that twelve hours, six million miles have fled into the past.

Now take a look at Mars. It is a small, red mote in the sky, its diameter some four thousand miles. Sol is eight hundred thousand miles in diameter. Six million miles from Mars, then, can be crudely expressed by visualizing a point eight times the diameter of the Sun away from Mars, and you have the distance that the Empress of Kolain had come from Mars.

But the ship was heading in at an angle, and the six million miles did not subtend the above arc. From Venus Equilateral, the position of the Empress of Kolain was more like two diameters of the Sun away from Mars, slightly to the north, and on the side away from Sol.

It may sound like a problem for the distant future, this pointing a radio beam at a planet, but it is no different from Galileo's attempts to see Jupiter through his Optik Glass. Of course, it has had refinements that have enabled man to make several hundred hours of exposure of a star on a photographic plate. So if men can maintain a telescope on a star, night after night, to build up a faint image, they can also maintain a beamed transmission wave on a planet.

All you need is a place to stand; a firm, immobile platform. The three-mile-long, one-mile-diameter mass of Venus Equilateral offered such a platform. It rotated smoothly, and upon its "business" end a hardened and highly polished set of rails maintained projectors that were pointed at the planets. These were parabolic reflectors that focussed ultra-high-frequency waves into tight beams which were hurled at Mars, Terra, and Venus for communication.

And because the beams were acted upon by all of the trivia in the Solar System, highly trained technicians stood their tricks at the beam controls. In fifty million miles, even the bending of electromagnetic waves by the Sun's mass had to be considered. Sunspots made known their presence. And the vagaries of land transmission were present in a hundred ways due to the distance and the necessity of concentrating every milliwatt of available power on the target.

This problem of the Empress of Kolain was different. Spaceships were invisible, therefore the beam-control man must sight on Mars and the mechanical cam would keep the ship in sight of the beam.

The hours went past in a peculiar mixture of speed and slowness. On one hand the minutes sped by swiftly and fleetingly, each tick of the clock adding to the lost moments, never to be regained. Time, being precious, seemed to slip through their fingers like sifting sand.

On the other hand, the time that must be spent in preparation of the equipment went slow. Always it was in the future, that time when their experiment must either prove a success or a failure. Always there was another hour of preparatory work before the parabolic reflector was mounted; and then another hour before it swung freely and perfectly in its new mounting. Then the minutes were spent in anticipation of the instant that the power stage of transmitter was tested and the megawatts of ultra-high-frequency energy poured into the single rod that acted as a radiator.

It was a singularly disappointing sight. The rod glowed not, and the reflector was the same as it was before the rod drew power. But the meters read and the generators moaned, and the pyrometers in the insulators mounted as the small quantity of energy lost was converted into heat. So the rod drew power, and the parabolic reflector beamed that power into a tight beam and hurled it out on a die-true line.

Then the cam was installed. The time went by even slower then, because the cam must be lapped and polished to absolute perfection, not only of its own surface but to absolute concentricity to the shaft on which it turned.

But eventually the job was finished, and the men stood back, their eyes expectantly upon Don Channing and Walt Franks.

Don spoke to the man chosen to control the beam. "You can start any time now. Keep her knifed clean, if you can."

The man grinned at Channing. "If the devils that roam the void are with us we'll have no trouble. We should all pray for a phrase used by some characters in a magazine I read once: 'Clear ether!' We could use some right now."

He applied his eyes to the telescope. He fiddled with the verniers for a brief time, made a major adjustment on a larger handwheel, and then said, without removing his eye from the 'scope, "That's it, Dr. Channing."

Don answered: "O.K., Jim, but you can use the screen now. We aren't going to make you squint through that pipe for the next few hours straight."

"That's all right. I'll use the screen as soon as you can prove we're right. Ready?"

Franks closed a tiny switch. Below, in the transmitter room, relays clicked and heavy-duty contacts closed with blue fire. Meters began to climb upward across their scales, and the generators moaned in a descending whine. A shielded monitor began to glow, indicating that full power was vomiting from the mouth of the reflector.

And out from the projector there went, like a spear-head, a wave-front of circularly polarized microwaves. Die-true they sped, crossing the void like a line of sight to an invisible spot above Mars and to the left. Out past the Sun, where they bent inward just enough to make Jim's job tough. Out across the open sky they sped at the velocity of light, and taking sixteen minutes to get there.

Ten minutes went by. The receiver was silent save for a constant crackle of cosmic static.

"Could be," admitted Franks. "Jim, waggle that beam a bit, and slowly. When we hit 'em, we'll know it because we'll hear 'em a half-hour later. Take it easy and slowly. We've used up thirteen of our fifty-odd hours. We can use another thirty or so just in being sure."

Jim began to make the beam roam around the invisible spot in the sky. He swept the beam in microscopic scans, up and down, and advancing the beam by one-half of its apparent width at the receiver for each sweep.

It was a terrific strain, this necessary wait of approximately a half-hour between each minor adjustment and the subsequent knowledge of failure. Jim gave up the 'scope because of eyestrain, and though Don and Walt had confidence that the beam-control man was competent to use the cross-ruled screen to keep Mars on the beam, Jim was none too sure of himself, and so he kept checking the screen against the 'scope.

At the end of the next hour of abject failure, Walt Franks began to scribble on a pad of paper. Don came over to peer over Franks' shoulder, and because he couldn't read Walt's mind, he was forced to ask what the engineer was calculating.

"I hope not. Look, Don, we're moving on the orbit of Venus, at Venus' orbital velocity. Oh, all right, say it scientifical: We are circling Sol at twenty-one point seven five miles per second. The reflected wave starts back right through the beam, remember?"

"I get it," shouted Channing in glee. "Thirty-two minutes' transmission time at twenty-one point seven five miles per second gives us—ah—"

Walt looked up from his slide rule. "Fifty-two thousand, two hundred and twenty-four miles," he said.

"But why do you always get there second with your genius?" complained Walt with a pseudo-hurt whine. "So how to establish it?"

"Can't use space radar for range," grunted Channing. "That would louse up the receiver. We've got everything shut off tight, you know. How about some visual loran?"

"I'd suggest an optical range finder excepting that the base-line of three miles—the length of Venus Equilateral—isn't long enough to triangulate for that fifty-two thousand—"

"Two hundred and twenty-four miles," finished Walt with a grin. "Proceed, genius, with caution."

"So we mount a couple of mirrors at either end of the station, and key a beam of light from the center, heading each way. When the pulses arrive at the space flitter at the same time, he's in position. We'll establish original range by radar, of course, but once the proper interval or range is established, the pilot can maintain his own position by watching the pulsed-arrival of the twin-flickers of light. Just like loran, excepting that we'll use light, and we can key it so it will run alternately, top and bottom. To maintain the proper angle, all the pilot will have to do is to keep the light alternating—fluently. Any overlapping will show him that he's drifted."

Walt made a canvass of the machine shop gang, and came back, saying: "Couple of hours, God willing."

The mounting of the mirrors at either end of the station took little time. It was the amount of detailed work that took time; the devising of the interrupting mechanism; and the truing-up of the mirrors that took the time.

Then it became evident that there was more. There were several hundred doorways centered on the axis of Venus Equilateral that must be opened, the space cleared of packing cases, supplies, and in a few cases machinery had to be partially dismantled to clear the way. A good portion of Venus Equilateral's personnel of three thousand were taken off their jobs, haled out of bed for the emergency, or made to work through their play period, depending upon which shift they worked.

The machinery could be replaced, the central storage places could be refilled, and the many doors closed again. But the central room containing the air plant was no small matter. Channing took a sad look at the lush growth of Martian saw grass and sighed. It was growing nicely now, they had nurtured it into lusty growth from mere sprouts in trays and it was as valuable—precisely—as the lives of the three thousand-odd that lived, loved, and pursued happiness on Venus Equilateral. It was a youthful plant, a replacement brought in a tearing hurry from Mars to replace the former plant that was heaved out by the well-meaning Burbank.

Channing closed his eyes and shuddered in mock horror. "Chop out the center," he said.

The "center" meant the topmost fronds of the long blades; their roots were embedded in the trays that filled the cylindrical floor. Some of the blades would die—Martian saw grass is tender in spite of the wicked spines that line the edge—but this was an emergency with a capital E.

Cleaning the centermost channel out of the station was no small job. The men who put up Venus Equilateral had no idea that someone would be using the station for a sighting tube some day. The many additions to the station through the years made the layout as regular and as well-planned as the Mammoth Cave in Kentucky.

So for hour upon hour, men swarmed in the central, weightless channel and wielded acetylene torches, cutting steel. Not in all cases, but there were many. In three miles of storage rooms, a lot of doors and bulkheads can be thrown up without crowding the size of the individual rooms.

Channing spoke into the microphone at the north end of Venus Equilateral, and said: "Walt? We've got a sight. Can you see?"

"That was quite a stretch, Walt. That 'hour, God willing,' worked itself into four hours, God help us."

"O.K., so I was optimistic. I thought that those doors were all on the center line."

"They are supposed to be, but they aren't huge and a little misalignment can do a lot of light-stopping. Can we juggle mirrors now?"

"Yup. He thinks he's at the right distance now. But he's got a light outfit, and this radar can be calibrated to the foot. Is the mirror-dingbat running?"

"Brother," groaned Channing, "if I had one of those death rays that the boys were crowing about back in the days before space-hopping became anything but a bit of fiction, I'd scorch your ears—or burn 'em off—or blow holes in you—or disintegrate you—depending on what stories you read. I haven't heard such a lousy pun in seventeen years—Hey, Freddie, you're a little close. Run out a couple of miles, huh?—and, Walt, I've heard some doozies."

There was a click in the phones and a cheerful voice chimed in with: "Good morning, fellows. What's with the Great Quest?"

"Yeah. We're still up against the main trouble with telephones—the big trouble, same as back in 1887—our friends have no telephone! You'd be surprised how elusive a spaceship can be in the deep. Sort of a non-existent, microscopic speck, floating in absolutely nothing. We have a good idea of where they should be, and possibly why and what—but we're really playing with blindfolds, handcuffs, ear plugs, mufflers, nose clamps, and tongue-ties. I am reminded—Hey, Freddie, about three more hundred yards—of the two blind men."

"Who—me? Listen, Dr. Channing, you're the bird on the tape line. You have no idea just how insignificant you look from fifty-odd thousand miles away. Put a red-hot on the 'finders and have 'im tell me where the ship sits."

"O.K., Freddie, you're on the beam and I'll put a guy on here to give you the dope. Right?"

"Right," echoed Arden breaking in on the phone. "And I'm going to bring you a slug of coffee and a roll. Or did you remember to eat recently?"

"You get your own girl," snorted Channing. "And besides, you are needed up here. We've got work to do."

Once again the signal lashed out. The invisible waves drove out and began their swift rush across the void. Time, as it always did during the waiting periods, hung like a Sword of Damocles. The half-hour finally ticked away, and Freddie called in: "No dice. She's as silent as the grave."

Minutes added together into an hour. The concentric wave left the reflector and just dropped out of sight.

"I'd like to tighten it down," objected Walt. "I think we're losing power and we can't increase the power—but we could tighten the beam."

"Too bad you can't wave it back and forth like a fireman squirting water on a lawn," said Arden.

"Firemen don't water lawns—" began Walt Franks, but he was interrupted by a wild yell from Channing.

Freddie called in excitedly: "Something went by just now and I don't think it was Christmas!"

"We might have hit 'em a dozen times in the last ten minutes and we'll never know it," said Channing. "But the spaceliners can be caught. Let's shoot at them like popping ducks. Shotgun effect. Look, Walt, we can electronically dance the beam at a high rate of speed, spraying the neighborhood. Freddie can hear us return because we have to hit them all the time and the waver coming on the way back will pass through his position again and again. We'll set up director elements in the reflector, distorting the electrical surface of the parabolic reflector. That'll divert the beam. By making the phases swing right, we can scan the vicinity of the Empress of Kolain like a flying spot television camera."

Walt turned to one of the technicians and explained. The man nodded. He left for Franks' laboratory and Walt turned back to his friends.

"Here shoots another couple of hours. I, for one, am going to grab forty winks."

Jim, the beam-control man, sat down and lighted a cigarette. Freddie let his flitter coast free. And the generators that fed the powerful transmitter came whining to a stop. But there was no sleep for Don and Walt. They kept awake to supervise the work, and to help in hooking up the phase-splitting circuit that would throw out-of-phase radio frequency into the director-elements to swing the beam.

Then once again the circuits were set up. Freddie found the position again and began to hold it. The beam hurled out again, and as the phase-shift passed from element to element, the beam swept through an infinitesimal arc that covered thousands of miles of space by the time the beam reached the position occupied by the Empress of Kolain.

Like a painter, the beam painted in a swipe a few hundred miles wide and swept back and forth, each sweep progressing ahead of the stripe before by less than its width. It reached the end of its arbitrary wall and swept back to the beginning again, covering space as before. Here was no slow, irregular swing of mechanical reflector, this was the electronically controlled wavering of a stable antenna.

And this time the half hour passed slowly but not uneventfully. Right on the tick of the instant, Freddie called back: "Got 'em!"

It was a weakling beam that came back in staccato surges. A fading, wavering, spotty signal that threatened to lie down on the job and sleep. It came and it went, often gone for seconds and never strong for so much as a minute. It vied, and almost lost completely, with the constant crackle of cosmic static. It fought with the energies of the Sun's corona and was more than once the underdog. Had this returning beam carried intelligence of any sort it would have been wasted. About all that could be carried on a beam as sorry as this was the knowledge that there was a transmitter—and that it was transmitting.

But its raucous note synchronized with the paint-brush wiping of the transmitter. There was no doubt.

Don Channing put an arm around Arden's waist and grinned at Walt Franks. "Go to work, genius. I've got the Empress of Kolain on the pipe. You're the bright-eyed lad that is going to wake them up! We've shot almost twenty hours of our allotted fifty. Make with the megacycles, Walter. Arden and I will take in a steak, a moom pitcher, and maybe a bit of woo. Like?" he asked the girl.

Walt Franks smiled and stretched lazily. He made no move to the transmitter. "Don't go away," he cautioned them. "Better call up Joe and order beer and sandwiches for the boys in the back room. On you!"

"Make with the signals first," said Channing. "And lay off the potables until we finish this silly job."

"You've got it. Is there a common, garden variety, transmitting key in the place?"

Don removed his arm from Arden's waist. He picked up a spanner and advanced on Franks.

"No!" objected Arden. "Poison him—I can't stand the sight of blood. Or better, bamboo splinters under the fingernails. He knows something simple, the big bum!"

"I want to key the beam. Y'see, Don, we're using the same frequency, by a half dozen megacycles, as their meteor spotter. I'm going to retune the beam to their frequency and key it. Realize what'll happen?"

"Sure," agreed Don, "but you're still missing the boat. You can't transmit keyed intelligence with an intermittent contact."

"International Code is a series of dots and dashes, you may know. Our wabbling beam is whipping through the area in which the Empress of Kolain is passing. Therefore the contact is intermittent. And how could you tell a dot from a dash?"

"Easy," bragged Walt Franks. "We're not limited to the speed of deviation, are we?"

"Yes—limited by the speed of the selsyn motors that transfer the phase-shifting circuits to the director radiators. Yeah, I get it, Edison, and we can wind them up to a happy six or eight thousand r. p. m. Six would get us a hundred cycles per second—a nice, low growl."

"And how will they receive that kind of signal on the meteor spotter?" asked Arden.

"The officer of the day will be treated to the first meteor on record that has intermittent duration—it is there only when it spells in International Code!"

Prying the toy transmitting key from young James Burke was a job only surpassed in difficulty by the task of opening the vault of the Interplanetary Bank after working hours. But Burke, Junior, was plied with soda pop, ice cream, and candy. He was threatened, cajoled, and finally bribed. And what Venus Equilateral paid for the toy finally would have made the toy manufacturer go out and look for another job. But Walt Franks carried the key to the scene of operations and set it on the bench to look at it critically.

"A puny gadget, at that," he said, clicking the key. "Might key a couple of hundred watts with it—but not too long. She'd go up like a skyrocket under our load!"

Walt opened up a cabinet and began to pull out parts. He piled several parts on a bread board, and in an hour had a very husky thyraton hooked into a circuit that was simplicity itself. He hooked the thyraton into the main power circuit and tapped the key gingerly. The transmitter followed the keyed thyraton and Don took a deep breath.

"Used to. Forgot it when I came to Venus Equilateral. Used to hold a ham ticket on Terra. But there's no use hamming on the station here where you can wake somebody by yelling at the top of your voice. The thing to ask is, 'Does anyone know code on board the Empress of Kolain?'"

They forgot their keying circuit and began to adjust the transmitter to the frequency used by the meteor spotter. It was a job. But it was done, all the way from the master oscillator stage through the several frequency doubler stages and to the big power-driver stage. The output stage came next, and then a full three hours of tinkering with files and hacksaws were required to adjust the length of the main radiator and the director elements so that their length became right for the changed frequency.

He began to rattle the key. In the power room the generators screamed and the lights throughout the station flickered just a bit at the sudden surges.

Don Channing said to Arden: "If someone of the Empress of Kolain can understand code—"

The Empress of Kolain was zipping along in its silent passage through the void. It was an unseen, undetected, unaware bit of human manufacture marking man's will among the stars. In all the known universe it moved against the forces of celestial mechanics because some intelligent mote that infested the surface of a planet once had the longing to visit the stars. In all the Solar System, most of the cosmic stuff was larger than it—but it alone defied the natural laws of space.

Because it alone possessed the required outside force spoken of in Newton's "Universal Laws."

Dinner was being served in the dining room. A group of shapely girls added grace to the swimming pool on the promenade deck. The bar was filled with a merry crowd which in turn were partly filled with liquor. A man in uniform, the Second Officer, was throwing darts with a few passengers in the playroom, and there were four oldish ladies on sabbatical leave who were stricken with mal-de-void.

The passage up to now had been uneventful. A meteor or two had come to make the ship swing a bit—but the swerve was less than the pitch of an ocean vessel in a moderate sea and it did not continue as did an ocean ship. Most of the time the Empress of Kolain seemed as steady as solid rock.

Only the First Officer, on the bridge, and the Chief Pilot, far below in the Control Room, knew just how erratic their course truly was. But they were not worried. They were not a shell, fired from a gun; they were a spaceship, capable of steering themselves into any port on Venus when they arrived and the minute wobbulations in their course could be corrected when the time came. For nothing had ever prevented a ship of space from seeing where it was going.

Then the meteor screen flashed into life. A circle of light appeared in the celestial globe and the ship's automatic pilot swerved ever so little. The dot of light was gone.

Throughout the ship, people laughed nervously. A waiter replaced a glass of water that had been set too close to the edge of the table and a manly-looking fellow dived into the swimming pool to haul a good-looking blonde to the edge again. She'd been in the middle of a swan dive when the swerve came and the ship had swerved without her. The resounding smack of feminine stomach against the water was of greater importance than the meteor, now so many hundred miles behind.

The flash of light returned and the ship swerved again. Upon the third swerve, the First Officer was watching the celestial globe with suspicion. He went white. It was conceivable that the Empress of Kolain was about to encounter a meteor shower.

He marked the place and set his observation telescope in synchronism with the celestial globe. He searched the sky. There was nothing but the ultimate starry curtain in the background. He snapped a switch and the voice of the pilot came out of a speaker in the wall.

"Tony, take the levers, will you please? Something is rotten in the State of Denmark."

Hendall scribbled on the telautograph and then abandoned the small 'scope. The flashing in the celestial globe continued, but the ship no longer danced in its path. Hendall went up into the big dome.

The big twenty-inch Cassegrain showed nothing at all, and Hendall returned to the bridge scratching his head. Nothing on the spotting 'scope and nothing on the big instrument.

That intermittent spot was large enough to mean a huge meteor. But wait. At the speed of the Empress, it should have retrogressed in the celestial globe unless it was so huge and so far away—but Sol didn't appear on the globe and it was big and far away, bigger by far. Nothing short of a planet at less-than-planetary distances would do this.

Hendall went to a cabinet and withdrew a cable with a plug on either end. He plugged one end into the test plug on the meteor spotter and the opposite end into the speaker. A low humming emanated from the speaker in synchronism with the flashing of the celestial globe.

Hendall went to the main communication microphone and spoke. His voice went all over the Empress of Kolain from pilot room and cargo spaces to swimming pool and infirmary.

Dancers stopped in midstep. Swimmers paused and then made their way to the edges of the pool and sat with their feet dangling in the warm water. Diners sat with their forks poised foolishly.

Hendall continued: "I believe that something never before tried is being attempted. I am forced against my better knowledge to believe that some agency is trying to make contact with us; a spaceship in flight! This is unknown in the annals of space flying and is, therefore, indicative of something important. It would not have been tried without preparations unless an emergency exists.

"However, the requirements of an officer of space do not include a knowledge of code because of the lack of communication with the planets while in space. Therefore, I request that any person with a working knowledge of International Morse will please present himself to the nearest officer."

Then the door of the bridge opened and Third Officer Jones entered with a thirteen-year-old youngster at his heels. The boy's eyes went wide at the sight of the instruments on the bridge, and he looked around in amazed interest.

The boy swelled visibly. You could almost hear him thinking: "He called me 'mister'!"

Then he went to the table by the speaker and reached for pencil and paper. "It's code all right," he said. Then Timmy winked at Jones, "He has a lousy fist!"

"—course and head for Terra direct"—the beam faded for seconds—"Venusian fever and you will be quarantined.

"Calling CQ, calling CQ, calling CQ. Calling Empress of Kolain ... empowered us to contact you and convey ... message—you are requested to correct your course and head ... a plague of Venusian fever and you—Johnson of Interplanet has empowered us ... the following message: 'You are requested to correct your ... head for Terra direct.' Calling CQ...."

"Sure," smiled Hendall, "it is fairly plain. It tells us that Keg Johnson of Interplanet wants us to head for Terra direct because of a plague of Venusian fever that would cause us to stay in quarantine. That would ruin the Line Moss. Prepare to change course, Mr. Jones!"

"There is only one outfit in the Solar System that could possibly think of a stunt like this. And that is Channing and Franks. This signal came from Venus Equilateral!"

"'As soon as this signal—intelligible—at right angles to your course for ten minutes. That will take—out of—beam and reflected—will indicate to us—left the area and know of our attempt.'"

"They're using a beam of some sort that indicates to them that we are on the other end but we can't answer. Mr. Jones, and Pilot Canton, ninety degrees north for ten minutes! Call the navigation officer to correct our course. I'll make the announcement to the passengers. Mr. Harris, you are given the freedom of the bridge for the remainder of the trip."

Mr. Harris was overwhelmed. He'd learn plenty—and that would help him when he applied for training as a space officer; unless he decided to take a position with Venus Equilateral when he grew up.

The signal faded from the little cruiser and silence prevailed. Don spoke into the microphone and said: "Run her up a millisecond," to the beam controller. The beam wiped the space above the previous course for several minutes and Franks was sending furiously:

Channing told the man in the cruiser to return. He kicked the main switch and the generators whined down the scale and coasted to a stop. Tube filaments darkened and meters returned to zero.

"O.K., Warren. Let the spinach lay. Get the next crew to clean up the mess and polish the set-up into something presentable. I'll bet a cooky that we'll be chasing spaceships all the way to Pluto after this. We'll work it into a fine thing and perfect our technique. Right now I owe the gang a dinner."

Interlude:

When necessity dictates a course of action and the course of action proves valuable, it is but a short step to the inclusion of the answer into the many facets of modern technical civilization. Thus it was that not many months after Venus Equilateral successfully established planet-to-ship communications with the "Empress of Kolain" that all course constants were delivered to the relay station and thereafter messages were transmitted as a part of the regular business of Interplanetary Communications.

This, of course, offered another problem. Ships in space were in the position of being able to catch messages but were not able to answer back. It would take, perhaps, another emergency to set up conditions which demanded the reverse of the problem of contacting a ship in space.

But there was a more immediate problem. Spacecraft were protected from meteors by means of radar that was coupled to the steering panels of the ships; when a meteor threatened, the ship merely turned aside by that fraction of a degree that gave it safety.

It took, however, but a few meteors, and the resulting few fractions of a degree to shunt the swiftly moving ship out of the coverage-area of the ship-seeking beams from Venus Equilateral. Then the power and ingenuity of Venus Equilateral was wasted on vacant space and the messages intended for the ships went undelivered.

Since the ship must avoid meteors, and the meteors could not be diverted from their courses, there was but one answer: Swerve the ship and let the messages go hang, for a message is of no use to a riddled spacecraft!

But, thought several people, if the meteor cannot be steered, perhaps it might be removed....

RECOIL

Walter Franks sat in the director's office; his feet on the director's desk. He was smoking one of the director's cigarettes. He was drinking the director's liquor, filched shamelessly from the director's private filing cabinet where it reposed in the drawer marked "S." Drawer "B" would have given beer, but Walt preferred Scotch.

He leaned forward and dropped the director's cigarette into the director's wastebasket and then he pressed the button on the desk and looked up.

But it was not the director's secretary who entered. It was his own, but that did not disturb Franks. He knew that the director's ex-secretary was off on Mars enjoying a honeymoon with the director.

Jeanne entered and smiled. "Must you call me in here to witness you wasting the company's time?" she asked in mock anger.

"You should live so long," she said with a smile. She stuck her tongue out at him.

Walt thumbed his way through the mail, making notations on some, and setting others aside for closer reading. He came to one and tossed it across the desk at Jeanne. She took the message and read:

"Scram, Jeanne. There are times when you can't work worth a darn. Mostly when you're thinking of that husband of yours. What's he got that I haven't?"

"Me," said Jeanne slyly. She arose and started for the door. "Oh," she said, "I almost forgot. Warren phoned and said that the turret is ready for a try-out."

"Fine," said Walt. "Swell." He unfolded himself from the chair with alacrity and almost beat the girl to the door.

"I know, but we can stand it. After all, since Don took over this affair, Venus Equilateral is an up and running business. We're out of the Government subsidy class now, and are making money. If this works, we'll make more. It's worth a gamble."

"Why, since this business of contacting ships-at-space has become so universally liked, we have a tough time keeping ships on the mobile beam. That's because they are always ducking out of the way of loose meteorites and stuff, and that screws up their course. We can't see 'em, and must take their position on the basis of their expected course. We never know whether we hit 'em until they land.

"Now I've been trying to devise a space gun that will blast meteors directly instead of avoiding them by coupling the meteor detector to the autopilot."

"Not exactly. Popping at them with any kind of a rifle would be like trying to hit a flying bird with a spitball. Look, Jeanne, speed on the run from Mars to Terra at major opposition is up among the thousands of miles per second at the turnover. A meteor itself may be blatting along at fifty miles per second. Now a rifle, shooting a projectile at a few thousand feet per second, would be useless. You'd have the meteor in your lap and out of the other side while the projectile is making up its mind to move forward and relieve the pressure that is building up behind it due to the exploding powder.

"I've designed an electron gun. It is a superpowered, over-sized edition of the kind they used to use in kinescope tubes, oscilloscope tubes, and electron microscopes. Since the dingbat is to be used in space, we can leave the works of the gun open and project a healthy stream of electrons at the offending object without their being slowed and dispersed by an impeding atmosphere."

"Not so fast on the objections, gal," said Franks. "I've seen a simple oscilloscope tube with a hole in the business end. It was burned right through a quarter inch of glass because the fellows were taking pix and had the intensity turned up high. The sweep circuit blew a fuse and the beam stopped on one spot. That was enough to puncture the screen."

"A nine-inch tube. The electron gun in a nine-inch kinescope tube is only about four inches long and three-quarters of an inch in diameter. Mine, out there in the turret, is six feet in diameter and thirty feet long. I can fire out quite a bundle of electrons from a tube of that size."

"I do. This is the right place to do research of that kind. Out here on Venus Equilateral, we're in a natural medium for an electron gun, and we've the power requirements to run it. I can't think of any place in the system that offers better chances."

Jeanne shook her head. "I wish Channing were here. Things are wild enough when you are both working on something screwball, but I could get scared something fierce at the thought of either one of you working without the other."

"You two sort of act as balance wheels to one another's craziness. Oh, don't take that word to heart. Everybody on the relay station thinks the world of you two, myself included. Craziness in this case means a sort of friendly description of the way your brains work. Both of you dash off on tangents now and then, and when either one of you get off the beam, the other one seems to swing the weight required to bring the lost one back to the fold."

"That's a real mess of mixed metaphors, Jeanne. But I am going to surprise Don hairless when he gets back here and finds that I've done what people claimed couldn't be done. I'm going to be the bird whose bust sits in the Hall of Fame in between Edison, Einstein, Alexander Graham Bell, S. F. B. Morse, and—"

"Old Man River, Jack Frost, and Little Boy Blue," laughed Jeanne. "I hope it's not a bust, Walt."

Jeanne left, with Walt right behind her. Franks did not remain at the desk, however, but made his way from the office level to the outer skin of the relay station by way of a not-often-used stairway that permitted him to drop to the outer skin. Above his head were the first levels of apartmental cubicles occupied by the personnel of Venus Equilateral. Out here, Walt had but a scant thickness of steel between him and the void of space.

Franks came to a room built from outer skin to inner skin and about fifty feet in diameter. He unlocked the door with a key on his watch chain, and entered. Warren was waiting for him.

"I should know? We've been squirting ropes of electrons out to blank space for hours. She gets rid of them all right. But have we done any good? I dunno."

"The detector hasn't blinked once. But when she does, your electron gun will pick it up a thousand miles before it gets here, and will follow the darned thing until it gets a half thousand miles out of sight."

"That sounds fine. It's a good thing that we don't have to swivel that mess of tube around a whole arc in actual use. It would take too long. But we'll put one in each quadrant of a spaceship and devise it so that its working arc will be small enough to make it work. Time enough to find that out after we know if it works."

"That's something that I've been wondering about," said Warren. "Why didn't we build a small one out here and evacuate the skin for a few hundred feet? We could set up a few chunks of iron and squirt electrons at them."

"And have the folks upstairs screaming? Nope. I've a hunch that when this beam hits something hard, it will create quite a ruckus. It would be fine to have a hunk blown right off the skin, wouldn't it?"

"Here's our chance," snapped Walt. "We've about fifteen seconds to work on this one."

He looked out of a tiny window, and saw that the big tube had lined up with the tiny model that was a monitor for the big tube. He sighted through the model, which in itself was a high-powered telescope, and he saw the jagged meteor rushing forward at an angle to the station. It would miss by many miles, but it would offer a good target.

Walt Franks grasped the power switch and thrust it down part way. Meters leaped up their scales and from somewhere there came the protesting whine of tortured generators. Through the window, nothing very spectacular was happening. The cathode glowed slightly brighter due to the passage of current through its metal and out of the coated surface. But the electrostatic stresses that filled the gaps between the accelerator and focussing anodes was no more visible than the electricity that runs a toy motor. Its appearance had not changed a bit, but from the meters, Walt Franks knew that megawatts of electronic power, in the shape of high-velocity electrons, were being poured from the cathode, accelerated by the ring anodes; and focussed to a narrow beam by the focussing anodes. And from the end of the framework that supported these anodes, a stream of high-velocity electrons poured forth, twelve inches in diameter.

Through the telescope, the meteor did not seem to be disturbed. It exploded not, neither did it melt. It came on inexorably, and if the inanimate nickel and iron of a meteor can be said to have such, it came on saucily and in utter disregard for the consequences.

Frantically, Walt cranked the power up higher and higher, and the lights all over the station dimmed as the cathode gun drained the resources of the station.

Then in desperation, Walt slammed the power lever down to the bottom notch. The girders strained in the tube from the terrific electrostatic stresses, and for a second, Walt was not certain that the meteor was not finally feeling the effects of the electron bombardment.

An insulator arced where it led the high-voltage lines that fed the anodes through the wall. Immediately it flashed over, and the room filled to the brim with the pungent odor of burning insulation. A medium-voltage anode shorted to one of the high-voltage anodes, and the stress increased in the tube. They broke from their moorings, these anodes, and plunged backward, down the tube toward the cathode. They hit, and it was enough to jar the whole tube backward on the gimbals.

The shock warped the mounting of the tube, and it flexed slightly, but sufficiently to bring the farthermost and highest voltage anode into the electron stream. It glowed redly, and the secondary emission raved back through the series of electrodes, heating them and creating more warpage.

Then the pyrotechnics stopped. Great circuit breakers crashed open up in the power room hundreds of feet above them, high in the station.

Walt Franks looked out through the window at the tangled mess that had been a finely machined piece of equipment. He saw the men looking quizzically at him as he turned away from the window, and with a smile that cost him an effort, he said: "All right, so Marconi didn't get WLW on his first try, either. Come on, fellows, and we'll clean up this mess."

With the utter disregard that inanimate objects show toward the inner feelings of the human being, the meteor alarm blinked again and the bell rang. The pilot tube swiveled quickly to one side, lining up with the spot in the celestial globe of the meteor detector. In the turret that housed the big tube, motors strived against welded commutators and the big tube tried to follow.

Don Channing smiled at Arden. "Mrs. Channing," he said, "must you persist in keeping me from my first love?"

Arden smiled winningly. "Naturally. That's what I'm here for. I intend to replace your first love entirely and completely."

"I'll permit you to attend to your so-called first love during eight hours every day, provided that you remember to think of me every half-hour."

"That's fine. But you really aren't fair about it. We were on Terra for two weeks. I was just getting interested in a program outlined by one of the boys that works for Interplanet, and what happened? You hauled me off to Mars. We stayed for a week at the Terraland Hotel at Canalopsis and the first time that Keg Johnson came to see us with an idea and a sheaf of papers, you rushed me off to Lincoln Head. Now I'm scared to death that some guy will try to open a blueprint here; at which I'll be rushed off to Palanortis Country until someone finds us there. Then it'll be the Solar Observatory on Mercury or the Big Glass on Luna."

Arden soothed Don's ruffled feelings by sitting on his lap and snuggling. "Dear," she said in a voice that positively dripped, "we're on a honeymoon, remember?"

Don stood up, dumping Arden to the floor. "Yeah," he said, "but this is the highest velocity honeymoon that I ever took!"

"And it's the first one I was ever on where the bridegroom took more time admiring beam installations than he took to whisper sweet nothings to his gal. What has a beam transmitter got that I haven't got?"

"One: Its actions can be predicted. Two: It can be controlled. Three: It never says anything original, but only repeats what it has been told. Four: It can be turned off."

"Yes—rumor!" stormed Arden with a chuckle. "Keep you from your first love, me eye. I'll play second fiddle to nothing, Donald. I'll just replace your original first love, but I'm too stinking bright to make you forget it entirely. That, my sweet, is why I brought you here. You can go chase the rumor whilst I do a bit of shopping. May I borrow your checkbook?"

"Rumor has it," said Arden in hyperbolic tones, "that two gentlemen, by name James Baler and Bernard Carroll, who have spent years digging up and studying the ancient Martian Artifacts, have recently uncovered a large and strange type of vacuum tube that seems to have been used by the Martians as a means of transmitting power. Since I felt that the time had come for the honeymooners to spend at least eight minutes apart, I insisted upon Lincoln Head for our next stop because Lincoln Head happens to have been the scene of some rare happenings, if rumor—"

She caught Don on the point of the chin with a pillow and effectively smothered him. She followed her advantage with a frontal attack that carried him backward across the bed, where she landed on top viciously and proceeded to lambaste him with the other pillow.

It was proceeding according to plan, this private, good-natured war, until a knock on the door brought a break in operations. Channing struggled out from beneath Arden and went to the door, trying to comb his hair by running spread fingers through it. He went with a sense of failure caused by Arden's quiet laugh and the statement that he resembled a bantam rooster.

The man at the door apologized, and then said: "I'm Doug Ferris of the Triworld News."

"I didn't know that Triworld News was interested in the wedded life of the Channings. Why doesn't Triworld wait until we find out about it ourselves?"

"Triworld does not care to pry into the private life of the newly wed Channing family," laughed Doug. "We, and the rest of the system, do not give a damn whether Mrs. Channing calls you Bunny-bit or Sugar-pie—"

"—we've got something big to handle. I can't get a thing out of the gang at Canalopsis, they're all too busy worrying."

"And so you came here? What do you expect to get out of us? We're not connected in any way with Canalopsis."

"I know," said Doug, "but you do know space. Look, Channing, the Solar Queen has been missing since yesterday morning!"

"See what I mean? What I want to know is this: What is your opinion on the matter? You've lived in space for years, on Venus Equilateral and you've had experience beyond anybody I can reach."

"That's what I thought. Now if you were running the spaceport at Canalopsis, what would your own private opinion be?"

"It won't be official. I'll corroborate anything you say before it is printed, and so on. But I want an unofficial opinion, too. If you want this withheld, say so, but I still want a technical deduction to base my investigation on. I don't understand the ramifications and the implications of a missing ship. It is enough to make Keg Johnson's hair turn gray overnight, though, and I'd like to know what is so bad before I start to turn stones."

"Well, keep it off the record until Canalopsis gives you the go-ahead. I can give you an opinion, but I don't want to sound official."

"Doubt it like the devil. Meteor detectors are many and interconnected on a spaceship, as well as being alarmed and fused to the nth degree. Any trouble with them will bring a horde of ringing bells all through the ship which would bring the personnel a-running. They just don't go wrong for no reason at all."

"Suppose that so many meteors came from all directions that the factors presented to the autopilot—"

"No dice. The possibility of a concentration of meteors from all directions all about to pass through a certain spot in space is like betting on two Sundays in a row. Meteors don't just run in all directions, they have a general drift. And the meteor detecting equipment would have been able to pick up the centroid of any group of meteors soon enough to lift the ship around it. Why, there hasn't been a ship hit by a meteor in ten years."

"And if it had been," continued Channing, "the chances are more than likely that the ship wouldn't have been hit badly enough to make it impossible to steer, or for the crew to shoot out message tubes which would have landed on Canalopsis."

"Look, there's one thing I don't understand," said Doug. "Spacecraft are always dodging meteors, yet Venus Equilateral seems immune."

"It's the velocity," explained Don. "Venus Equilateral is traveling at the same speed as Venus, of course. A spacecraft hits it up in the hundreds of miles per second. Say two hundred and seventy miles per second, which is about ten times the orbital velocity of Venus Equilateral. Then with a given dispersion of meteors throughout space, any spacecraft has ten times the possible chances of encounter because the ship covers ten times the volume in the same time. Besides, truly missing meteors is a hypothetical problem."

"To avoid only those whose courses will intersect yours would demand some sort of course predicting gear that would read the course of the oncoming meteor and apply it in a space problem to the predicted course of the ship. That's just too much machinery, Doug. So spacecraft merely turn aside for anything that even looks close. They don't take any chances at all," said Don Channing. "They can't afford to."

"Suppose that the ship ducked a big shower and it went so far out of course that they missed Mars?"

"A standard ship of space is capable of hitting it up at about four G all the way from Terra to Mars at major opposition and end up with enough power and spare cathodes to continue to Venus in quadrature. Now the velocity of the planets in their orbits is a stinking matter of miles per second, while the top speed of a ship in even the shortest passage runs up into four figures per second. You'd be surprised at what velocity you can attain at one G for ten hours."

"It runs to slightly less than two hundred and fifty miles per second, during which you've covered only four million miles. In the shortest average run from Venus to Terra at conjunction, a skimpy twenty-five million miles, your time of travel is a matter of twenty-five hours odd, running at the standard two G. Your velocity at turnover—or the halfway point where the ship stops going up from Terra and starts to go down to Venus—is a cool five hundred miles per second. So under no condition would the ship miss its objective badly enough to cause its complete loss. Why, this business is run so quickly that were it not for the saving in time and money that amounts to a small percentage at the end of each flight, the pilot could head for his planet and approach the planet asymptotically."

"You're forcing my mind into accepting something that has never happened before, and something that has no basis for its—"

"You mean piracy? I wonder. We've all read tales of the Jolly Roger being painted on the side of a sleek ship of space while the pirate, who is a fine fellow at heart though uninhibited, hails down the cruiser carrying radium. He swipes the stuff and kisses all the women whilst menacing the men with a gun-hand full of searing, coruscating, violently lethal ray pistol. But that sounds fine in stories. The trick is tougher than it sounds, Douglas. You've got to catch your rabbit first."

"Meaning that finding a ship in space to prey upon is somewhat less difficult than juggling ten billiard balls whilst riding a horse blindfolded. Suppose you were to turn pirate. This is what would happen:

"You'd get the course of the treasure ship from the spaceport, fine and good, by resorting to spies and such. You'd lie in wait out there in the blackness of space, fixing your position by the stars and hoping that your error in fix was less than a couple of hundred thousand miles. The time comes. You look to your musket, sharpen your cutlass, and see to the priming of your derringers that are thrust into the red sash at your waist. You are right on the course, due to your brilliant though lawless navigator who was tossed out of astrogator's school for filching the teacher's whiskey. Then the treasure ship zoops past at a healthy hundred miles per second and you decide that since she is hitting it up at two G, you'd have had to start from scratch at a heck of a lot better to catch her within the next couple of light years."

"But suppose you took the course as laid and applied the same acceleration? Suppose you followed on the heels of your quarry until you were both in space? You could do it then, couldn't you?"

"Gosh," said Channing, "I never thought of that. That's the only way a guy could pirate a ship—unless he planted his men on board and they mutinied."

"It might be," admitted Channing. "It'd have to occur near beginning or end, of course, though. I can't think of anything safer than being shot at out of a gun of any kind while both crates are hitting it up at a couple of hundred miles per second and at a distance of a few miles apart. It would be all right if you were both running free, but at two G acceleration, you'd have to do quite a bit of ballistic gymnastics to score a hit."

"Except that the meteor detector would show the position of the pirate craft in the celestial globe and the interconnecting circuits would cause the treasure ship to veer off at a sharp angle. Shucks, Doug, this thing has got too many angles to it. I can't begin to run it off either way. No matter how difficult it may sound, there are still ways and means to do it. The one thing that stands out like a sore thumb is the fact that the Solar Queen has turned up missing. Since no inanimate agency could cause failure, piracy is the answer."

"Not positive. There are things that might cause the ship to founder. But what they are depends on too many coincidences. It's like hitting a royal flush on the deal, or filling a full house from two pairs."

"Well, thanks, Channing. I'm heading back to Canalopsis right now. Want to come along?"

Channing looked at Arden, who was coming from the dressing room carrying her coat and he nodded. "The gal says yes," he grinned. "Annoy her until I find my shoes, will you?"

The trip from Lincoln Head to Canalopsis was a fast one. Doug drove the little flier through the thin air of Mars at a breakneck speed and covered the twelve hundred miles in just shy of an hour. At the spaceport, Channing found that he was not denied the entrance as the reporter had been. He was ushered into the office of Keg Johnson, and he and the manager of the Canalopsis Spaceport greeted Don with a worried expression on his face.

Don shook his head with a sympathetic smile. "Like trying to find a grain of sand on a beach—a specified grain, I mean. Wouldn't know how to go about it."

Keg nodded. "I thought as much. That leaves her out of the picture. Well, up to now space travel has been about as safe as spending the evening in your easy-chair. Hello, Arden, how's married life?"

"Can't tell yet," she said with a twinkle. "I've got to find out whether I can break him of a dozen bad habits before I'll commit myself."

"I wish you luck, Arden, although from that statement, it's Don that needs the luck."

"We came to see if there was anything we could do about the Solar Queen," offered Channing.

"What can anybody do?" asked Keg with spread hands. "About all we can do is to put it down in our remembrances and turn to tomorrow. Life goes on, you know," said Keg in a resigned tone, "and either we keep up or we begin to live in the past. Are you going to stay here for a day or two?"

"Well, suppose you register at the Terraland and meet me back here for lunch. If anything occurs, I'll shoot you a quickie." Keg looked at his watch and whistled. "Lordy," he said ruefully. "I didn't know how late it was. Look, kids, I'll run you downtown myself, and we'll all have lunch at the Terraland. How's that?"

It was during lunch that a messenger raced into the dining room and handed Keg a letter. Keg read, and then swore roundly. He tossed the letter across the table to Don and Arden.

"Hellion Murdoch is a man of considerable ability as a surgeon and a theoretical physicist," explained Don. "He was sentenced to the gas chamber ten years ago for trying some of his theories out on human beings without their consent. He escaped with the aid of fifteen or twenty of his cohorts who had stolen the Hippocrates right out of the private spaceport of the Solarian Medical Research Institute."

"And they headed for the unknown," offered Keg. "Wonder where they've been for the last ten years?"

"I'll bet a hat that they've been in the Melapalan Jungle, using the machine shop of the Hippocrates to fashion guns. That machine shop was a dilly, if I remember correctly."

"It was. The whole ship was just made to be as self-sustaining as it could be. They used to run all over the System in it, you know, chasing bugs. But look, Don, if I were you, I'd begin worrying about Venus Equilateral. That's where he'll hit next."

"Something that will drive him right out to the relay station," said Keg in a sorrowful tone. "Sorry, Don, but when I put an end to all space shipping for a period of six weeks, Hellion Murdoch will be sitting in your lap."

"He sure will," said Channing nervously. "Arden, are you willing to run a gantlet?"

"Reasonably sure, or I wouldn't take you with me. Unless Murdoch has managed to build himself a couple of extra ships, we've got a chance in three that he'll be near one of the other two big spaceports. So we'll slide out of here unannounced and at a peculiar time of day. We'll load up with gravanol and take it all the way to the station at six G."

"He may have two or three ships," said Keg. "A man could cover all the standard space shipping in three, and he might not have too bad a time with two, especially if he were only out looking for those which weren't paid for. But, look, I wouldn't check out of the Terraland if I were you. Keep this under cover. Your heap is all ready to take sky from Canalopsis Spaceport and you can leave directly."

Johnson smiled and nodded. "I'll give you time to get there anyway. But I've no control over what will be done at Northern Landing or Mojave. They may kick over the traces."

"Arden, we're moving again," laughed Don. "Keg, ship us our duds as soon as this affair clears up." Channing scribbled a message on the back of Murdoch's letter. "Shoot this off to Walt Franks, will you? I won't wait for an answer, that'll take about fifty minutes, and by that time I'll have been in space for twenty."

They paused long enough to stop at the nurse's office at the spaceport for a heavy shot of gravanol and a thorough bracing with wide adhesive tape. Then they made their way to the storage space of the spaceport where they entered their small ship. Channing was about to send the power lever home when the figure of Keg Johnson waved him to stop.

Channing snarled and thrust the power lever down to the last notch. The little ship leaped upward at five G, and was gone from sight in less than a minute.

"I told him that there was a wild-eyed pirate on the loose, and that he might take a stab at the station. We are coming in as soon as we can get there and to be on the lookout for us on the landing communications radio, and also for anything untoward in the nature of space vessels."

"Then this is not exactly a shock," said Arden, waving the message from Murdoch.

"Not exactly," said Channing dryly. "Now look, Arden, you go to sleep. This'll take hours and hours, and gabbing about it will only lay you out cold."

"I know, but that's the gravanol, not you. The tape will keep you intact, and the gravanol will keep you awake without nausea. But you can't get something for nothing, Arden, and when that gravanol wears off, you'll spend ten times as long with one-tenth of the trouble you might have had. So take it easy for yourself now and later you'll be glad that you aren't worse."

The sky blackened, and Channing knew that they were free in space. Give them another fifteen minutes and the devil himself couldn't find them. With no flight plan scheduled and no course posted, they might as well have been in the seventeenth dimension. As they emerged from the thin atmosphere, there was a fleeting flash of fire from several miles to the east, but Channing did not pay particular attention to it. Arden looked through a telescope and thought she saw a spaceship circling, but she could not be sure.

The trip out to the station was a monotonous series of uneventful hours, proceeding along one after the other. They dozed and slept most of the time, eating sparingly and doing nothing that was not absolutely necessary.

Turnabout was accomplished and then the deceleration began, equally long and equally monotonous. It was equally inactive. Channing tried to plan, but it failed because he could not plan without talking and discussing the affair with his men. Too much depended upon their co-operation. He fell into a morose, futile feeling that made itself evident in grousing; Arden tried to cheer him, but Don's usually bubbling spirit was doused too deep. Also, Arden herself was none too happy, which is necessary before one can cheer another.

Then they sighted the station and Channing's ill spirit left. A man of action, what he hated most was the no-action business of just sitting in a little capsule waiting for the relay station to come up out of the sky below. Once it was sighted, Channing foresaw action, and his grousing stopped.

They zipped past the station at a distance of ten miles, and Channing opened the radio.

"Joe has declared a drought for the duration," said Franks with a laugh. "He thinks we can't think on Scotch."

"Murdoch's crew? Sure, they're circling at about five miles, running around in the plane of the ecliptic. Keep running on the colure and the chances are that you won't even see 'em. But, Don, they can hear us!"

"There are two of them running around the station at different heights from north to south. The third is circling in a four-mile circle on a plane five miles south of the station. We've picked up a few HE shells, and I guess that, if you try to make a landing there, you'll be shot to bits. That devil is using the meteor detector for a gun pointer."

"Yop. All we have to do is clear away some of the saw grass again. Not too much, though, because it hasn't been too long since we cut it before. I get you all right."

"I'm in the beam control north, I've got a portable mike, and I walk over to the mirror and begin to tinker with the screws. Ouch! I've skun me a knuckle. Now look, Don, I'm going inside and crack the passage end. I've broadcast throughout the station that it is to be cracked, and the men are swarming all over the axis of the station doing just that. Come—a-running!"

Channing circled the little ship high to the north and came down toward the axis of the station. He accelerated fiercely for a portion of the time, and then made a slambang turnabout. A pilot light on the instrument panel gleamed, indicating that some of the plates were strained and that the ship was leaking air. Another light lit, indicating that the automatic pressure control was functioning, and that the pressure was maintained, though it might not long be.

Then in deceleration, Channing fought the ship on to a die-straight line with the open door at the north end. He fixed the long, long passageway in the center of his sights, and prayed.

The ship hit the opening squarely, and only then did their terrific speed become apparent. Past bulkhead after bulkhead they drove, and a thin scream came to their ears as the atmosphere down in the bowels of the station was compressed by the tiny ship's passage.

Doors slammed behind the ship as it passed, and air locks were opened, permitting the station's center to fill to its normal pressure once more.

Then the rocketing ship slowed. Channing saw a flash of green and knew that the Martian saw grass was halfway down the three-mile length of the station. He zipped past storerooms and rooms filled with machinery, and then the ship scraped lightly against one of the bulkheads.

It caromed from this bulkhead against the next, hitting it in a quartering slice. From side to side the ship bounced, crushing the bulkheads and tearing great slices from the flanks of the ship.

It slowed, and came to rest against a large room full of packing cases, and was immediately swarmed over by the men of Venus Equilateral.

They found Channing partly conscious. His nose was bleeding but otherwise he seemed all right. Arden was completely out, though a quick check by the station's medical staff assured Don that she would be all right as soon as they gave her a workout. He was leaving the center of the station when Franks came puffing up the stairway from the next lowest level.

"Gosh," he said. "It's a real job trying to guess where you stopped. I've been hitting every hundred feet and asking. Well, that was one for the book."

"Yeah," groaned Don. "Come along, Walt. I want a shower. You can give the resumé of the activities while I'm showering and trying to soak this adhesive off. Arden, lucky girl, will be unconscious when Doc rips it off; I never liked the way they remove tape."

Channing was finishing the shower when Walt mentioned that it was too bad that they hadn't started his electron gun a few weeks sooner.

"No. I've been tinkering with an idea of mine. If we had another month to work on it, I think we might be able to clip Murdoch's ears."

"Not at all. So far we might be able to fry a smelt at twenty feet, or we could cook us a steak. But I haven't been able to do a thing yet. We had it working once, and I think we heated a meteor somewhat, but the whole thing went blooey before we finished the test. I've spent the last week and a half fixing the thing up again, and would have tried it out on the next meteor, but your message brought a halt to everything but cleaning up the mess and making ready just in case we might think of something practical."

"I'll put in my first oar by seeing the gadget. Wait till I find my pants, and I'll go right along."

Don inspected the installation and whistled. "Not half bad, sonny, not half bad."

"Well, for one thing, you've been running on the wrong track. You need more power."

"Sure," grinned Walt. "More power, he says. I don't see how we can cram any more soup into this can. She'll melt."

"Functionally, what are you trying to accomplish? Take it on the basis of a solid shot, like they used to use back in the sailing ship days."

"Well," said Walt thoughtfully, "I'd say they were trying to heave something large enough to do damage."

"Precisely. Qualifying that statement a little, you might say that the projectile transmits the energy of the powder charge to its objective."

"And it is possible to transmit that energy mechanically. I think if we reason this idea out in analogy, we might be able to do it electrically. First, there is the method. There is nothing wrong with your idea, functionally. Electron guns are as old as radio. They—"

"How long do people have to be married before people stop asking that darn fool question?" asked Arden.

"I meant that. I ran into Warren, who told me that the brains were down here tinkering on something that was either a brilliant idea or an equally brilliant flop—he didn't know which. What goes?"

"Here's where we open a psychopathic ward," said Arden sadly. "So far, Venus Equilateral is the only community that hasn't had a village idiot. But no longer are we unique. Seriously, Walt?"

"Sure enough," said Channing. "He's got an idea here that may work with a little tinkering."

"Well, sound recording has come a long way from the tinfoil cylinder that scratched out: 'Mary had a little lamb!' And transportation has come along swell from the days of sliding sledges. You may have the nucleus of an idea, Walt. But I meant its operation instead of its efficiency."

"We have an electron gun of super size," explained Walt. "The cathode is a big affair six feet in diameter and capable of emitting a veritable storm of electrons. We accelerate them by means of properly spaced anodes of the proper voltage level, and we focus them into a nice bundle by means of electrostatic lenses—"

"Whoah, Tillie, you're talking like the venerable Buck Rogers himself. Say that in words of one cylinder, please," chuckled Arden.

"Well, any voltage gradient between electrodes of different voltage acts as a prism, sort of. When you have annular electrodes of the proper size, shape, and voltage difference, they act as a lens."

"Nope. It is the space between them. With light or electrons a convex lens will converge the light no matter which direction the light is coming from."

"Uh-huh. I see in a sort of vague manner. Now, fellows, go on from there. What's necessary to make this dingbat tick?"

"That's nothing unusual," said Arden. "Can't we go into Joe's? You can't think without a tablecloth, either."

"What I'm thinking is this, Walt. You've been trying to squirt electrons like a fireman runs a hose. Walt, how long do you suppose a sixteen-inch rifle would last if the explosives were constantly replaced and the fire burned constantly?"

"A gun is an overloaded machine," said Don. "Even a little one. The life of a gun barrel is measured in seconds; totalling up the time of transit of all the rounds from new gun to worn barrel gives a figure expressed in seconds. Your electron gun, Walt, whether it be fish, flesh, or fowl, must be overloaded for an instant."

"Is overload a necessary requirement?" asked Arden. "It seems to me that you might be able to bore a sixteen-inch gun for a twenty-two. What now, little man?"

"By the time we get something big enough to do more than knock paint off, we'll have something bigger than a twenty-two," grinned Channing. "I was speaking in terms of available strength versus required punch. In the way that a girder will hold tremendous overloads for brief instants, a gun is overloaded for milliseconds. We'll have a problem—"

"O.K., aside from that, have you figured out why I haven't been able to do more than warm anything larger than a house brick?"

"Sure," laughed Channing. "What happens in a multi-grid radio tube when the suppressor grid is hanging free?"

"Sure," said Walt. "We fire off a batch of electrons, and the first contingent that arrives charges the affair so that the rest of the beam sort of wriggles out of line."

"Your meteor is going to take on a charge of phenomenal negative value, and the rest of your beam is going to be deflected away, just as your electron lenses deflect the original beam," said Channing. "And now another thing, old turnip. You're squirting out a lot of electrons. That's much amperage. Your voltage—velocity—is nothing to rave about even though it sounds high. Watts is what you want, to corn a phrase."

"Phew," said Walt. "Corn, he says. Go on, prodigy, and make with the explanations. I agree, we should have more voltage and less quantity. But we're running the stuff at plenty of voltage now. Nothing short of a Van Der Graf generator would work—and while we've got one up on the forty-ninth level, we couldn't run a supply line down here without reaming a fifty-foot hole through the station, and then I don't know how we'd get that kind of voltage down here without ... that kind of stuff staggers the imagination. You can't juggle a hundred million volts on a wire. She'd squirt off in all directions."

"Another thing, whilst I hold it in my mind," said Channing, thoughtfully. "You go flinging electrons off the station in basketful after basketful, and the next bird that drops a ship on the landing stage is going to spot-weld himself right to the south end of Venus Equilateral. It wouldn't be long before the station would find itself being pulled into Sol because of the electrostatic stress—if we didn't run out of electrons first!"

"I hardly think that we'd run out—but we might have a tough time flinging them away after a bit. Could it be that we should blow out a fist full of protons at the same time?"

"Might make up a concentric beam and wave positive ions at the target," said Channing. "Might help."

"Same way we make the electron gun work. Fire it off at a devilish voltage. Run your electron velocity up near the speed of light; the electrons at that speed will acquire considerable mass, in accordance with Lorenz's equation which shows that as the velocity of a mass reaches the speed of light, its mass becomes infinite. With a healthy mass built up by near-light velocities, the electrons will not be as easy to deflect. Then, too, we can do the damage we want before the charge can be built up that will deflect the stream. We ram 'em with a bundle of electrons moving so fast that the charging effect can not work; before the space charge can build up to the level required for self-nullification of our beam, the damage is done."

"And all we need is a couple of trillion volts. Two times ten to the twelfth power. Grrr."

"I can see that you'll need a tablecloth," said Arden. "You birds can think better over at Joe's. Come along and feed the missus, Don."

Channing surveyed the instrument again, and then said: "Might as well, Walt. The inner man must be fed, and we can wrangle at the same time. Argument assists the digestion—and vice versa."

"Now," said Channing as the dishes were pushed aside, clearing a space on the table. "What are we going to do?"

"That's what I've been worrying about," said Walt. "Let's list the things that make our gun ineffective."

"That's easy. It can't dish out enough. It's too dependent upon mobility. It's fundamentally inefficient because it runs out of ammunition too quick, by which I mean that it is a sort of gun with antiseptic bullets. It cures its own damage."

"You can't whirl a hunk of tube the size and weight of a good-sized telescope around fast enough to shoot holes in a racing spaceship," said Channing. "Especially one that is trying to dodge. We've got to rely upon something that can do the trick better. Your tube did all right following a meteor that rung in a course that can be predicted, because you can set up your meteor spotter to correct for the mechanical lag. But in a spaceship that is trying to duck your shot, you'll need something that works with the speed of light. And, since we're going to be forced into something heavy and hard hitting, its inertia will be even more so."

"Cyclotron, betatron or synchrotron. One of those dinguses that whirls nucleons around like a stone on a string until the string breaks and sends the stone out at terrific speed. We need a velocity that sounds like a congressional figure."

"Yeah," drawled Channing, "A wheezy old heap that cries out in anguish every time the magnets are charged. I doubt that we could move the thing without it falling apart. The betatron is the ticket."

"If I had to increase the output of either one, I could do it a lot quicker with the betatron," said Channing. "In a cyclotron, the revolution of the ions in their acceleration period is controlled by an oscillator, the voltage output of which is impressed on the D chambers. In order to speed up the ion stream, you'd have to do two things. One: Build a new oscillator that will dish out more power. Two: Increase the strength of the magnets.

"But in the betatron, the thing is run differently. The magnet is built for A. C. and the electron gun runs off the same. As your current starts up from zero, the electron gun squirts a bouquet of electrons into a chamber built like a pair of angel's food cake tins set rim to rim. The magnet's field begins to build up at the same time, and the resulting increase in field strength accelerates the electrons and at the same time, its increasing field keeps the little devils running in the same orbit. Shoot it with two-hundred-cycle current, and in the half cycle your electrons are made to run around the center a few million times. That builds up a terrific velocity—measured in six figures, believe it or not. Then the current begins to level off at the top of the sine wave, and the magnet loses its increasing phase. The electrons, still in acceleration, begin to whirl outward. The current levels off for sure and begins to slide down—and the electrons roll off at a tangent to their course. This stream can be collected and used. In fact, we have a two-hundred-cycle beam of electrons at a couple of billion volts. That, brother, ain't hay!"

"Then how do you hope to increase this velocity? If it is easier to run this up than it would be the cyclotron, how do we go about it?"

Channing smiled and began to draw diagrams on the tablecloth. Joe looked over with a worried frown, and then shrugged his shoulders. Diagrams or not, this was an emergency—and besides, he thought, he needed another lesson in high powered gadgetry.

"The nice thing about this betatron," said Channing, "is the fact that it can and does run both ends on the same supply. The current and voltage phases are correct so that we do not require two supplies which operate in a carefully balanced condition. The cyclotron is one of the other kinds; though the one supply is strictly D. C., the strength of the field must be controlled separately from the supply to the oscillator that runs the D plates. You're sitting on a fence, juggling knobs and stuff all the time you are bombarding with a cyc.

"Now let us inspect the supply of the betatron. It is sinusoidal. There is the catch. There is the thing that makes it possible. That single fact makes it easy to step the power up to terrific quantities. Since the thing is fixed by nature so that the output is proportional—electron gun initial velocity versus magnetic field strength—if we increase the input voltage, the output voltage goes up without having to resort to manipulistic gymnastics on the part of the operator."

"Don't make fun of a great man's name," said Arden. "If it wasn't for Clerk Maxwell, we'd still be yelling out of the window at one another instead of squirting radio beams all over the Solar System."

"Go on, Don, Walt and I will finish this argument after we finish Hellion Murdoch."

"May I?" asked Channing with a smile. He did not mind the interruption; he was used to it in the first place and he had been busy with his pencil in the second place. "Now look, Walt, what happens when you smack a charged condenser across an inductance?"

"You generate a damped cycle of the amplitude of the charge on the condenser, and of frequency equal to the L, C constants of the condenser and inductance. The amplitude decays according to the factor Q, following the equation for decrement—"

"Never mind, I've got it here on my whiteboard," smiled Channing, pointing to the tablecloth. "You are right. And the purity of the wave?"

"Sinusoidal ... hey! That's it!" Walt jumped to his feet and went to the telephone.

"The betatron we have runs off of a five-hundred-volt supply," chuckled Channing. "We can crank that up ten to one without running into any difficulty at all. Five-hundred-volt insulation is peanuts, and the stuff they put on wires nowadays is always good for ten times that just because it wouldn't be economical to try to thin the installation down so that it only protects five hundred. I'll bet a crank that he could crank the input up to fifty thousand volts without too much sputtering—though I wouldn't know where to lay my lunch hooks on a fifty-thousand-volt condenser of any appreciable capacity. Well, stepping up the rig ten to one will dish us out just shy of a couple of thousand million volts, which, as Brother Franks says, is not hay!"

Walt returned after a minute and said: "Warren's measuring the inductance of the betatron magnet. He will then calculate the value of C required to tune the thing to the right frequency and start to achieve that capacity by mazing up whatever high-voltage condensers we have on the station. Now, Don, let's calculate how we're going to make the thing mobile."

"That's a horse of a different color. We'll have to use electromagnetic deflection. From the constants of the electron stream out of our souped-up Suzy, we'll have to compute the necessary field to deflect such a beam. That'll be terrific, because the electrons are hitting it up at a velocity approaching that of light—maybe a hundred and seventy thousand miles per—and their mass will be something fierce. That again will help to murder Murdoch; increasing mass will help to keep the electrons from being deflected, since it takes more to turn a heavy mass—et cetera, see Newton's laws of inertia for complete statement. Have 'em jerk the D plates out of the cyc and bring the magnet frame down here—to the turret, I mean—and set 'em up on the vertical. We'll use that to run the beam up and down, we can't possibly get one hundred and eighty degree deflection, of course, but we can run the deflection over considerable range. It should be enough to catch a spaceship that is circling the station. For the horizontal deflection, what have we got?"

"Nothing. But the cyc magnet is a double pole affair. We could break the frame at the D plates and set one winding sidewise to the other and use half on each direction."

"Sure. Have one of Warren's gang fit the busted pole pieces up with a return-magnetic frame so that the field will be complete. He can weld some girders on and around in an hour. That gives us complete deflection properties up and down; left and right. We should be able to cover a ninety-degree cone from your turret."

"Too bad we haven't got some U-235 to use. I'd like to plate up one of his ships with some positive ions of U-235 and then change the beam to slow neutrons. That might deter him from his life of crime."

"Variations, he wants," said Arden. "You're going to impale one ship on a beam of electrons; one ship on a beam of U-235 ions; and what will you have on the third?"

"I'll think of something," said Channing. "A couple of hundred pounds of U-235 should make things hum, though."

"More like making them disappear," said Franks. "Swoosh! No ship. Just an incandescent mass falling into the Sun. I'm glad we haven't any purified U-235 or plutonium in any quantity out here. We catch a few slow neutrons now and then, and I wouldn't be able to sleep nights. The things just sort of wander right through the station as though it weren't here at all; they stop just long enough to register on the counter upstairs and then they're gone."

"Well, to work, people. We've got a job to do in the next three and a half days."

Those days were filled with activity. Hauling the heavy parts down to the turret was no small job, but it was accomplished after a lot of hard work and quite a bit of tinkering with a cutting torch. The parts were installed in the outer skin, and the crew with the torch went back over the trail and replaced the gaping holes they left in the walls and floors of Venus Equilateral. The engineering department went to work, and for some hours the place was silent save for the clash of pencil on paper and the scratching of scalps. The most popular book in the station became a volume on nuclear physics, and the second most popular book was a table of integrals. The stenographic force went to work combing the library for information pertaining to electronic velocities, and a junior engineer was placed in as buffer between the eager stenographers and the harried engineering department. This was necessary because the stenographers got to the point where they'd send anything at all that said either "electrons" or "velocity," and one of the engineers read halfway through a text on atomic structure before he realized that he had been sold a bill of goods. Wire went by the mile down to the turret, and men proceeded to blow out half of the meters in the station with the high-powered beam. Luckily, the thing was completely nonspectacular, or Murdoch might have gained an inkling of their activities. The working crew manipulated constants and made haywire circuits, and finally announced that the beam would deflect—if the calculations were correct.

"They'd better be," said Channing. He was weary. His eyes were puffed from lack of sleep, and he hadn't had his clothing off in three days.

"They'd better be right," said Channing ominously. "We're asking for a kick in the teeth. The first bundle of stuff that leaves our gun will energize Murdoch's meteor spotter by sheer electrostatic force. His gun mounts, which you tell me are coupled to the meteor detector for aiming, will swivel to cover the turret out here. Then he'll let us have it right in the betatron. If we don't get him first, he'll get us second."

"Don," said Walt in a worried voice. "How are we going to replace the charge on the station? Like the bird who was tossing baseballs out of the train—he quit when he ran out of them. Our gun will quit cold when we run out of electrons—or when the positive charge gets so high that the betatron can't overcome the electrostatic attraction."

"Venus Equilateral is a free grid," smiled Channing. "As soon as we shoot off electrons, Old Sol becomes a hot cathode and our station collects 'em until the charge is equalized again."

"And what is happening to the bird who is holding on to something when we make off with a million volts? Does he scrape himself off the opposite wall in a week or so—after he comes to—or can we use him for freezing ice cubes? Seems to me that it might be a little bit fatal."

"Didn't think of that," said Channing. "There's one thing, their personal charge doesn't add up to a large quantity of electricity. If we insulate 'em and put 'em in their spacesuits, they'll be all right as long as they don't try to grab anything. They'll be on the up and down for a bit, but the resistance of the spacesuit is high enough to keep 'em from draining out all their electrons at once, I recall the experiments with early Van Der Graf generators at a few million volts—the operator used to sit in the charged sphere because it was one place where he couldn't be hit by man-made lightning. It'll be rough, but it won't kill us. Spacesuits, and have 'em sit in plastic chairs, the feet of which are insulated from the floor by china dinner plates. This plastic wall covering that we have in the apartments is a blessing. If it were all bare steel, every room would be a miniature hell. Issue general instructions to that effect. We've been having emergency drills for a long time; now's the time to use the grand collection of elastomer spacesuits. Tell 'em we give 'em an hour to get ready."

Hellion Murdoch's voice came over the radio at exactly the second of the expiration of his limit. He called Channing and said:

Don squinted down the pilot tube of the meteor spotter and saw the Hippocrates passing. It was gone before he spoke, but the second ship came along, and the pilot tube leaped into line with it. Don checked meters on the crude panel before him, and then pressed the plastic handle of a long lever.

Crackles of electricity flashed back and forth through the station, and the smell of ozone arose. Electric light filaments leaned over crazily, trying to touch the inner walls of the glass. Panes of glass ran blue for an instant, and the nap of the carpets throughout the station stood bolt upright. Hair stood on end, touched the plastic helmet dome, discharged, fell to the scalp, raised again and discharged, fell once more, and then repeated this raising and falling, again and again and again. Electric clocks ran crazily, and every bit of electronic equipment on the station began to act in an unpredictable manner.

Then things settled down again as the solar emission charged the station to equilibrium.

Aboard the ship, it was another story. The celestial globe of the meteor spotter blazed once in a blinding light and then went completely out of control. It danced with pin points of light, and the coupler that was used to direct the guns went crazy. Turrets tried to swivel, but the charge raised hob with the electronic controls, and the guns raised once, and then fell, inert. One of them belched flame, and the shell went wild. The carefully balanced potentials in the driver tubes were upset, and the ship lost headway. The heavy ion stream from the driving cathode bent and spread, touching the dynodes in the tubes. The resulting current brought them to a red heat, and they melted down and floated through the evacuated tube in round droplets. Instruments went wild, and gave every possible answer, and the ship became a bedlam of ringing bells and flashing danger lights.

But the crew was in no shape to appreciate this display. From metal parts in the ship there appeared coronas that reached for the unprotected men, and seared their flesh. And since their gravity-apparent was gone, they floated freely through the air, and came in contact with highly charged walls, ceilings and floors; to say nothing of the standard metal furniture.

It was a sorry bunch of pirates that found themselves in a ship-without-motive-power that was beginning to leave their circular course on a tangent that would let them drop into the Sun.

"You never thought that it would be an electronics engineer that made the first energy gun, did you, Murdoch? I'm now going to take a shot at No. 3!"

No. 3's turrets swiveled around and from the guns flashes of fire came streaming. Channing punched his lever savagely, and once again the station was tortured by the effects of its own offensive.

Then, seconds later, armor-piercing shells began to hit Venus Equilateral. They hit, and because of the terrific charge, they began to arc at the noses. The terrible current passed through the fuses, and the shells exploded on contact instead of boring in before detonation. Metal was bent and burned, but only a few tiny holes resulted. As the charge on the station approached equilibrium once more, men ran with torches to seal these holes.

"Land—or die!" snapped Channing in a vicious tone. "I'm no humanitarian, Murdoch. You'd be better off dead!"

Channing pulled the lever for the third time, but as he did, Murdoch's ship leaped forward under several G. The magnets could not change in field soon enough to compensate for this change in direction, and the charge failed to connect as a bull's eye. It did expend some of its energy on the tail of the ship. Not enough to cripple the Hippocrates, but the vessel took on a charge of enough value to make things hard on the crew.

Metal sparked, and instruments went mad. Meters wound their needles around the end pegs. The celestial globe glinted in a riot of color and then went completely dead. Gun servers dropped their projectiles as they became too heavily charged to handle, and they rolled across the turret floors, creating panic in the gun crews. The pilot fought the controls, but the charge on his driver tubes was sufficient to make his helm completely unpredictable. The panel sparked at him and seared his hands, spoiling his nervous control and making him heavy-handed.

Murdoch's radio was completely dead. His ship was yawing from side to side as the static charges raced through the driver tubes. The pilot gained control after a fashion, and decided that he had taken enough. He circled the station warily and began to make a shaky landing at the south end.

Channing saw him coming, and with a glint in his eye, he pressed the lever for the fourth and last time.

Murdoch's ship touched the landing stage just after the charge had been driven out into space. The heavy negative charge on the Hippocrates met the heavy positive charge on Venus Equilateral. The ship touched, and from that contact, there arose a cloud of incandescent gas. The entire charge left the ship at once, and through that single contact. When the cloud dissipated, the contact was a crude but efficient welded joint that was gleaming white-hot.

Inside of the Hippocrates, men were frozen to their handholds. It was messy, and cleaning up the Hippocrates was a job not relished by those who did it.

A week went by before the snarled-up instruments were repaired. A week in which the captured Hippocrates was repaired, too, and used to transport prisoners to and material and special supplies from Terra, and Venus, and Mars. A week in which the service from planet to planet was erratic.

Then service was restored, and life settled down to a reasonable level. It was after this that Walt and Channing found time to spend an idle hour together. Walt raised his glass and said: "Here's to electrons!"

"Yeah," grinned Channing, "here's to electrons. Y'know, Walt, I was a little afraid that space might become a sort of Wild West show, with the ships bristling with space guns and betatrons and stuff like that. In which case you'd have been a stinking benefactor. But if the recoil is as bad as the output—and Newton said that it must be—I can't see ships cluttering up their insides with stuff that'll screw up their instruments and driver tubes. But the thing that amuses me about the whole thing is the total failure you produced."

"Don't you know? Have you forgotten? Do you realize that spaceships are still ducking around meteors instead of blasting them out of the way with the Franks Electron Gun? Or did you lose sight of the fact that this dingbat started out in life as a meteor-sweeper?"

Interlude:

Once the threat of piracy was over, Don Channing had an opportunity to think once more of the much-talked-about tube that had been found on the Martian Desert by Carroll and Baler. Predicated as a general rule, any medium used for the transmission of energy can be used as a means to transmit messages—intelligence, to use the more technical term. The reverse is not true, practically.

And since Don Channing's initial problem during these days was to devise means of two-way communication from ship to planet—if not ship to ship—he immediately returned to Mars to seek out Messrs. Baler and Carroll.

Strangely enough, the problem of communicating from planet to ship was not solved—nor would it be complete until some means of returning messages was devised. For the cams that kept the ship beams pointed to the place where the invisible spaceship was supposed to be had no way of knowing when the ship might swerve to miss a meteor. Many were the messages that went into space—undelivered—because a ship dodged a meteor that might have been dangerous. Postulating the rather low possibility of danger made little difference. Misdirected messages were of less importance than even the remote danger of death in the skies.

But Don Channing's luck was running low. On arriving at Lincoln Head, he discovered that Baler and Carroll had packed up their tube and left for Terra. Keg Johnson knew about it; he informed Channing that the foremost manufacturer of electrical apparatus had offered a lucrative bid for the thing as it stood and that Big Jim Baler had grinned, saying that the money that the Terran Electric Company was tossing around would permit the two of them, Carroll and himself, to spend the rest of their lives digging around the artifacts of Mars in style.

So Channing sent word to Venus Equilateral and told them to get in touch with either the Baler-Carroll combine or Terran Electric and make dicker.

Then he started to make the journey back to Venus Equilateral on the regular spacelanes....

OFF THE BEAM

Thirty hours out of Mars for Terra, the Ariadne sped along her silent, invisible course. No longer was she completely severed from all connection with the planets of the inner system; the trick cams that controlled the beams at Venus Equilateral kept the ship centered by sheer mathematics in spite of her thirty hours at two G, which brought her velocity to eleven hundred miles per second.

What made this trip ironic was the fact that Don Channing was aboard. The beams had been bombarding the Ariadne continually ever since she left Mars with messages for the Director of Communications. In one sense, it seemed funny that Channing was for once on the end of a communications line where people could talk to him but from which he could not talk back. On the other hand, it was a blessing in disguise, for the Director of Communications was beginning to paper-talk himself into some means of contacting Venus Equilateral from a spaceship.

A steward found Channing in the salon and handed him a 'gram. Channing smiled, and the steward returned the smile and added: "You'll fix these ships to talk back one day. Wait till you read that one—you'll burn from here to Terra!"

"Reading my mail?" asked Channing cheerfully. The average spacegram was about as secret as a postcard, so Channing didn't mind. He turned the page over and read:

"She will, too," grinned Don. "Well, I'd like to toss her one back, but she's got me there. I'll just fortify myself at the bar and think up a few choice ones for when we hit Mojave."

"Some day you'll be able to answer those," promised the steward. "Mind telling me why it's so tough?"

"Not at all," smiled Channing. "The problem is about the same as encountered by the old-time cowboy. It's a lot easier to hit a man on a moving horse from a nice, solid rock than it is to hit a man on a nice, solid rock from a moving horse. Venus Equilateral is quite solid as things go. But a spaceship's course is fierce. We're wobbling a few milliseconds here and a few there, and by the time you use that arc to swing a line of a hundred million miles, you're squirting quite a bit of sky. We're tinkering with it right now, but so far we have come up with nothing. Ah, well, the human race got along without electric lights for a few million years, we can afford to tinker with an idea for a few months. Nobody is losing lives or sleep because we can't talk with the boys back home."

"We've been hopping from planet to planet for quite a number of years, too," said the steward. "Quite a lot of them went by before it was even possible to contact a ship in space."

"And that was done because of an emergency. Probably this other thing will go on until we hit an emergency; then we shall prove that old statement about a loaf of bread being the maternal parent of a locomotive." Channing lit a cigarette and puffed deeply. "Where do we stand?"

"Thirty hours out," answered the steward. "About ready for turnover. I imagine that the power engineer's gang is changing cathodes about now."

"It's a long drag," said Channing. He addressed himself to his glass and began to think of a suitable answer for his wife's latest thrust.

Bill Hadley, of the power engineer's gang, spoke to the pilot's greenhouse below the ship. "Hadley to the pilot room; cathodes 1 and 3 ready."

"Pilot Greenland to Engineer Hadley: Power fade-over from even to odd now under way. Tubes 2 and 4 now dead; load on 1 and 3. You may enter 2 and 4."

Hadley cracked an air valve beside a circular air door. The hiss of entering air crescendoed and died, and then Hadley cracked the door that opened in upon the huge driver tube. With casual disregard for the annular electrodes that would fill the tube with sudden death if the pilot sent the driving power surging into the electrodes, Hadley climbed to the top of the tube and used a spanner to remove four huge bolts. A handy differential pulley permitted him to lower the near-exhausted cathode from the girders to the air door, where it was hauled to the deck. A fresh cathode was slung to the pulley and hoisted to place. Hadley bolted it tight and clambered back into the ship. He closed the air door and the valve, and then opened the valve that led from the tube to outer space. The tube evacuated and Hadley spoke once more to the pilot room.

The operation was repeated on tube 2, and then Pilot Greenland said: "Fade-back beginning. Power diminishing on 1 and 3, increasing on 2 and 4. Power equalized, acceleration two G as before. Deviation from norm: two-tenths G."

Hadley grinned at the crew. "You'd think Greenland did all that himself, the way he talks. If it weren't for autopilots, we'd have been all over the sky."

Tom Bennington laughed. He was an old-timer, and he said in a reminiscent tone: "I remember when we did that on manual. There were as many cases of mal-de-void during cathode change as during turnover. Autopilots are the nuts—look! We're about to swing right now, and I'll bet a fiver that the folks below won't know a thing about it."

A coincidence of mammoth proportions occurred at precisely that instant. It was a probability that made the chance of drawing a royal flush look like the chances of tomorrow coming on time. It was, in fact, one of those things that they said couldn't possibly happen, which went to prove only how wrong they were. It hadn't happened yet and probably wouldn't happen again for a million million years, but it did happen once.

Turnover was about to start. A relay circuit that coupled the meteor-spotter to the autopilot froze for a bare instant, and the coincidence happened between the freezing of the relay contacts and the closing of another relay whose purpose it was to shunt the coupler circuits through another line in case of relay failure. In the conceivably short time between the failure and the device that corrected failure, the Ariadne hit a meteor head-on.

The meteor, a small one as cosmic objects go, passed in through the broad observation dome at the top of the ship. Unhampered, it zipped through the central well of the Ariadne and passed out through the pilot's greenhouse at the bottom of the ship. Its speed was nothing worth noting; a scant twenty miles per second almost sunward. But the eleven hundred miles per second of the Ariadne made the passage of the meteor through the six hundred feet of the ship's length of less duration than the fastest camera shutter.

It passed through the main pilot room cable and scrambled those circuits which it did not break entirely. It tore the elevator system from its moorings. It entered as a small hole in the observation dome and left taking the entire pilot's greenhouse and all of the complex paraphernalia with it.

The lines to the driver tubes were scrambled, and the ship shuddered and drove forward at 10 gravities. An inertia switch tried to function, but the resetting solenoid had become shorted across the main battery and the weight could not drop.

Air doors clanged shut, closing the central well from the rest of the ship and effectively sealing the well from the crew.

The lights in the ship flickered and died. The cable's shorted lines grew hot and fire crept along its length and threatened the continuity. The heat opened fire-quenching vents and a cloud of CO₂ emerged together with some of the liquid gas itself. The gas quenched the fire and the cold liquid cooled the cable. Fuses blew in the shorted circuits—

And the Ariadne continued to plunge on and on at 10 gravities: the maximum speed possible out of her driving system.

The only man who remained aware of himself aboard the Ariadne was the man who was filled with gravanol and adhesive tape. No other person expected to be hammered down by high acceleration. Only Channing, intending to leave Terra in his own little scooter, was prepared to withstand high G. He, with his characteristic haste of doing anything slowly, was ready to make the Terra to Venus Equilateral passage at five or six gravities.

It might as well have caught him, too. With all of the rest unconscious, hurt, or dead, he was alone and firmly fastened to the floor of the salon under eighteen hundred pounds of his own, helpless weight.

And as the hours passed, the Ariadne was driving farther and farther from the imaginary spot that was the focus of the communicator beams from Venus Equilateral.

The newly replaced cathodes in the driving tubes were capable of driving the ship for about two hundred G-hours at one G, before exhaustion to the point of necessary replacement for safety purposes. The proportion is not linear, nor is it a square-law, but roughly it lies in the region just above linear, so that the Ariadne drove on and on through space for ten hours at ten G before the cathodes died for want of emitting surface. They died, not at once, but in irregular succession so that when the last erg of power was gone from the drivers it was zooming on a straight line tangent from its point of collision but rolling in a wild gyration through the void.

And twenty-five hundred miles per second, added to her initial velocity of eleven hundred miles per second summed up to thirty-six hundred miles per second. She should have had about seventy-five million miles to go at minus two G to reach Terra in thirty hours from the halfway point, where she turned ends to go into deceleration. Instead, the Ariadne after ten hours of misdirected ten-G acceleration was thirty million miles on her way, or about halfway to Terra. Three hours later, driving free, the Ariadne was passing Terra, having missed the planet by several million miles.

Back in space, at a no longer existent junction between the beams from Venus Equilateral and the Ariadne, Arden Channing's latest message was indicating all sorts of minor punishment for her husband when she got him home.

By the time that the Ariadne should have been dropping out of the sky at Mojave Spaceport, the ship would be one hundred and ninety million miles beyond Terra and flirting with the imaginary line that marked the orbit of Mars.

Weightless, Channing pursued a crazy course in the salon of the spinning ship. He ached all over from the pressure, but the gravanol had kept his head clear and the adhesive tape had kept his body intact. He squirmed around in the dimness and could see the inert figures of the rest of the people who had occupied the salon at the time of the mishap. He became sick. Violence was not a part of Channing's nature—at least he confined his violence to those against whom he required defense. But he knew that many of those people who pursued aimless orbits in the midair of the salon with him would never set foot on solidness again.

He wondered how many broken bones there were among those who had lived through the ordeal. He wondered if the medical staff of one doctor and two nurses could cope with it.

Then he wondered what difference it made, if they were to go on and on? Channing had a rough idea of what had happened. He knew something about the conditions under which they had been traveling, how long, and in what direction. It staggered him, the figures he calculated in his mind. It behooved him to do something.

He bumped an inert figure and grabbed. One hand took the back of the head and came away wet and sticky. Channing retched, and then threw the inert man from him. He coasted back against a wall, and caught a handrail. Hand-over-hand he went to the door and into the hall. Down the hall he went to the passengers' elevator shaft, and with no thought of what his action would have been on any planet, Channing opened the door and dove down the shaft for several decks. He emerged and headed for the sick ward.

He found the doctor clinging to his operating table with his knees and applying a bandage to one of his nurses' head.

"Unconscious, but unharmed. Both asleep in bed, thank God. So was I. Where were—? You're Channing; all doped up with gravanol and adhesive. Thank yourself a god for that one, too. I'm going to need both of my nurses, and we'll all need you."

"You'd better. Or any good I can do will be wasted. Better start right now. Here," the doctor produced a set of keys, "these will unlock anything on the ship but the purser's safe. You'll need 'em. Now get along and do something and leave the body-mending to me. Scram!"

"As best I can. But you're needed to get us help. If you can't, no man in the Solar System can. You're in the position of a man who can not afford to help in succoring the wounded and dying. It'll be tough, but there it is. Get cutting. And for Heaven's sake, get us two things: light and a floor. I couldn't do more than slap on tape whilst floating in air. See you later, Channing, and good luck."

The nurse squirmed, groaned, and opened her eyes. "What happened?" she asked, blinking into the doctor's flashlight.

"Tell you later, Jen. Get Fern out of her coma in the ward and then we'll map out a plan. Channing, get out of here!"

He found Hadley up in the instrument room with a half dozen of his men. They were a mass of minor and major cuts and injuries, and were working under a single incandescent lamp that had been wired to the battery direct by means of spare cable. The wire went snaking through the air in a foolish, crooked line, suspended on nothing. Hadley's gang were applying first aid to one another and cursing the lack of gravity.

"You can say that again—and then pitch in. You're Channing, of Communications, aren't you? We're going to have a mad scramble on the main circuits of this tub before we can unwind it. I don't think there's an instrument working in the whole ship."

"Won't try. About all we can do is replace the lighting system and hang the dead cathodes in again. They'll be all right to take us out of this cockeyed skew-curve and probably will last long enough to keep a half-G floor under us for tinkering, for maybe forty or fifty hours. Assistant Pilot Darlange will have to learn how to run a ship by the seat of his pants—as far as I can guess there isn't even a splinter of glass left in the pilot room—so he'll have to correct this flight by feel and by using a haywire panel."

"I know, Jimmy, but I've seen him work on a bum autopilot, and he can handle haywire all right. It'll be tough without Greenland, but Greenland—" Hadley let the sentence fall; there was no need to mention the fact that Greenland was probably back there with the rest of the wreckage torn from the Ariadne.

Jimmy nodded, and the action shook him from his position. He floated. He grabbed at a roll of tape that was floating near him and let it go with a laugh as he realized it was too light to do him any good.

"Too bad that this gyration is not enough to make a decent gravity at the ends, at least," snorted Hadley. He hooked Jimmy by an arm and hauled the man back to a place beside him. "Now look," he said. "I can't guess how many people are still in working condition after this. Aside from our taped and doped friend here, the only ones I have are we who were snoozing in our beds when the crush came. I'll bet a cookie that the rest of the crowd are all nursing busted ribs, and worse. Lucky that full ten G died slowly as the cathodes went out; otherwise we'd all have been tossed against the ceiling with bad effects.

"Jimmy, you're a committee of one to roam the crate and make a list of everyone who is still in the running and those who can be given minor repairs to make them fit for limited work. Doc has a pretty good supply of Stader splints; inform him that these are to be used only on men who can be useful with them. The rest will have to take to plaster casts and the old-fashioned kind of fracture support.

"Pete, you get to the executive desk and tell Captain Johannson that we're on the job and about to make with repairs. As power engineer, I've control of the maintenance gang, too, and we'll collect the whole, hale, and hearty of Michaels' crew on our merry way.

"Tom, take three of your men and begin to unravel the mess with an eye toward getting us lights.

"Tony, you can do this alone since we have no weight. You get the stale cathodes from the supply hold and hang 'em back in the tubes.

"Channing, until we get a stable place, you couldn't do a thing about trying to get help, so I suggest that you pitch in with Bennington, there, and help unscramble the wiring. You're a circuit man, and though power-line stuff is not your forte, you'll find that running a lighting circuit is a lot easier than neutralizing a microwave transmitter. Once we get light, you can help us haywire a control panel. Right?"

"Right," said Channing. "And as far as contacting the folks back home goes, we couldn't do a darned thing until the time comes when we should be dropping in on Mojave. They won't be looking for anything from us until we're reported missing; then I imagine that Walt Franks will have everything from a spinthariscope to a gold-foil electroscope set up. Right now I'm stumped, but we have seventeen hours before we can start hoping to be detected. Tom, where do we begin?"

Bennington smiled inwardly. To have Don Channing asking him for orders was like having Captain Johannson request the batteryman's permission to change course. "If you can find and remove the place where the shorted line is, and then splice the lighting circuit again, we'll have a big hunk of our work done. The rest of us will begin to take lines off of the pilot's circuits right here in the instrument room, so that our jury-controls can be hooked in. You'll need a suit, I think, because I'll bet a hat that the shorted circuit is in the well."

For the next five hours, the instrument room became a beehive of activity. Men began coming in driblets, and were put to work as they came. The weightlessness gave quite a bit of trouble; had the instrument panels been electrically hot, it would have been downright dangerous, since it was impossible to do any kind of work without periodically coming into contact with bare connections. Tools floated around the room in profusion, and finally Hadley appointed one man to do nothing but roam the place to retrieve "dropped" tools. The soldering operations were particularly vicious, since the instinctive act of flinging excess solder from the tip of an iron made droplets of hot solder go zipping around the room to splash against something, after which the splashes would continue to float.

Men who came in seeking to give aid were handed tools and told to do this or that, and the problem of explaining how to free a frozen relay to unskilled help was terrific.

Then at the end of five hours, Channing came floating in to the instrument room. He flipped off the helmet and said to Hadley: "Make with the main switch. I think I've got it."

With the coming of light, there came hope also. Men took a figurative hitch in their belts and went to work with renewed vigor. It seemed as though everything came to a head at about this time, too. Hadley informed Darlange that his jury-control was rigged and ready for action, and about the same time, the galley crew came in with slender-necked bottles of coffee and rolls.

"It was a job, making coffee," grinned the steward. "The darned stuff wanted to get out of the can and go roaming all over the place. There isn't a one of us that hasn't got a hot coffee scar on us somewhere. Now if he"—nodding at Darlange—"can get this thing straightened out, we'll have a real dinner."

"Hear that, Al? All that stands between us and a dinner is you. Make with the ship-straightening. Then we'll all sit around and wait for Channing to think."

Darlange called for everyone in the ship to hold himself down, and then he tied his belt to the frame in front of the haywired panel. He opened the power on drivers 1 and 2, and the ship's floor surged ever so little.

"I've got one eye on the gyrocompass," said Darlange. "When it stops turning, we're going straight. Then all we have to do is to set our bottom end along the line of flight and pack on the decel. Might as well do it that way since every MPS we can lose is to our advantage."

He snapped switches that added power to driver 3. Gradually the gyrocompass changed from a complex rotation-progression to a simpler pattern, and eventually the simple pattern died, leaving but one freedom of rotation. "I'm sort of stumped," grinned Darlange. "We're now hopping along, but rotating on our long axis. How we stop axial rotation with drivers set parallel to that axis I'll never guess."

"Tom, turn it against the rotation and apply the drivers on that until we tell you to stop."

An hour later the ship had ceased to turn. Then Darlange jockeyed the big ship around so that the bottom was along the line of flight. Then he set the power for a half-G, and everyone relaxed.

"You've done a fine job," he told Hadley. "And now I declare an hour off for dinner. Dr. MacLain has got a working medical center with the aid of a few people who understand how such things work, and the percentage of broken bones, though terrific in number, is being taken care of. The passengers were pretty restive at first, but the coming of light seemed to work wonders. This first glimmer of power is another. About nine or ten who were able to do so were having severe cases of skysickness." He smiled ruefully. "I'm not too sure that I like no-weight myself."

"Because I'm going to have to get a sight on Venus Equilateral before we can do anything. We'll have to beam them something, but I don't know what right now."

"Can we discuss that over a dinner?" asked the captain. "I'm starved, and I think that the rest of this gang is also."

"You're a man after my own heart," laughed Channing. "The bunch out at the station wouldn't believe me if I claimed to have done anything without drawing it up on a tablecloth."

"Now," said Channing over his coffee, "what have we in the way of electronic equipment?"

"One X-ray machine, a standard set of communicating equipment, one beam receiver with 'type machine for collecting stuff from your station, and so on."

"Some kind," admitted Channing. "But it emits something that we've never been able to detect except in an atmosphere where it ionizes the air into a dull red glow."

"You should have been wrecked on the Sorcerer's Apprentice," laughed Hadley. "They're the guys who have all that kind of stuff."

"The last time I heard, they were using a large hunk of their upper hull for a Van Der Graf generator."

"That would do it," said Channing thoughtfully. "But I don't think I'd know how to modulate a Van Der Graf. A betatron would be the thing. You can modulate that, sort of, by keying the input. She'd give out with hundred-and-fifty-cycle stuff. How much of a trick is it to clear the observation dome from the top?"

"Well, we've got a long, hollow tube in this ship. Knock out the faceted dome above, and we can rig us up a huge electron gun. We'll turn the ship to point at the station and beam 'em with a bouquet of electrons."

"Not too tough, I don't think. Down here," and Channing began to trace on the tablecloth, "we'll put in a hot cathode. About this level we'll hang the first anode, and at this level we'll put the second anode. Here'll be an acceleration electrode, and up near the top we'll put a series of focussing anodes. We'll tap in to the driver-tube supply and take off voltage to suit us. Might use a tube at that, but the conversion to make an honest electron gun out of it would disrupt our power, and then it would be impossible to re-make a driver out of it without recourse to a machine shop."

"We'll use the annular gratings that run around the central well at each level," said Channing. "We'll have a crew of men cut 'em free and insulate the resulting rings with something. Got anything?"

"There is a shipment of methyl-methacrylate rods for the Venus Power Company in hold 17," said the cargo master.

"It'll be tricky work, and you'll have to wait until your cut edge has cooled before you hook on the rods," mused Don. "But that's the ticket."

"Then this is where my tablecloth artistry falls flat. The focussing of an electron beam depends upon the electrode spacing and the voltage. Since our voltage is fixed if we take it from the drivers' electrodes, we'll have to do some mighty fine figuring. I'll need that scale drawing."

Channing's tablecloth engineering was not completely wasted. By the time the scale drawing was placed before him, Channing had half of the table filled with equations. He studied the drawing, and selected the levels which were to serve as electrodes. He handed the drawings to Hadley, and the power engineer began to issue instructions to his gang.

Then the central well began to swarm with space-suited men who bore cutting torches. Hot sparks danced from the cut girders that held the floorings, and at the same time, a crew of men were running cables from the various levels to the instrumented room. More hours passed while the circular sections were insulated with the plastic rods.

The big dome above was cut in sections and removed, and then the sky could be seen all the way from the bottom of the ship where the pilot's greenhouse should have been.

Channing looked it over and then remarked: "All we need now is an electron collector."

"I do. But we've got to have a source of supply. You can't toss baseballs off of the Transplanet Building in Northern Landing all afternoon, you know, without having a few brought to you now and then. Where do you think they come from?"

"We'd get along for the first umpty-gillion electrons, and then all the soup we could pack on would be equalized by the positive charge on the ship and we couldn't shoot out any more until we got bombarded by the sun—and that bombardment is nothing to write home about as regards quantity. We're presenting too small a target. What we need is a selective solar intake plate of goodly proportions."

"We could use a mental telepathy expert, too. Or one of those new beam tubes that Baler and Carroll dug up out of the Martian desert. I've heard that those things will actually suck power out of any source, and bend beams so as to enter the intake vent, or end."

"We haven't one of those, either. Fact of the matter is," grinned Channing, ruefully, "we haven't much of anything but our wits."

"Half armed, at least. Ah, for something to soak up electrons. I'm now wondering if this electron gun is such a good idea."

"That would leave us without either," said Don. "We'd be like the man who tossed baseballs off of one side and himself off the other—Hey! Of course, we have some to spare. We can cram electrons out of the business end, thus stripping the planetary rings from the atoms in our cathode. From the far side we'll shoot the canal rays, which in effect will be squirting protons, or the nuclei. Since the planetaries have left for the front, it wouldn't be hard to take the protons away, leaving nothing. At our present voltages, we might be able to do it." Channing began to figure again, and he came up with another set of anodes to be placed beyond the cathode. "We'll ventilate the cathode and hang these negative electrodes on the far side. They will attract the protons, impelled also by the positive charge on the front end. We'll maintain a balance that way, effectively throwing away the whole atomic structure of the cathode. The latter will fade, just as the cathodes do in the driving tubes, only we'll be using electronic power instead of sub-electronic. Y'know, Hadley, some day someone is going to find a way to detect the—we'll call it radiation for want of anything better—of the driver. And then there will be opened an entirely new field of energy. I don't think that anybody has done more about the so-called sub-electronic field than to make a nice, efficient driving device out of it."

"Well, let's get our canal-ray electrodes in place. We've got about two hours before they realize that we aren't going to come in at Mojave. Then another two hours of wild messages between Venus Equilateral and Mojave. Then we can expect someone to be on the lookout. I hope to be there when they begin to look for us. At our present velocity, we'll be flirting with the Asteroid Belt in less than nothing flat. That isn't too bad—normally—but we're running without any meteor detector and autopilot coupler. We couldn't duck anything from a robin's egg on up."

"It's been on the way for about twenty minutes," laughed Arden. "I timed it to arrive at Terra at the same time the Ariadne does. They'll send out a special messenger with it, just as Don is getting aboard his little scooter. It'll be the last word, for we're not following him from Terra to here."

"That's just the start. Before he gets done, Don will have every ship capable of answering back. I've found that you can catch him off base just once. He's a genius—one of those men who never make the same mistake twice. He'll never again be in a position to be on the listening end only."

"Don's answer should be on the way back by now," said Arden. "Could be you're right. Something should be done."

"Sure I'm right. Look at all the time that's wasted in waiting for a landing to answer 'grams. In this day and age, time is money, squared. The latter is to differentiate between this time and the first glimmering of speedy living."

"Was there a first glimmering?" asked Arden sagely. "I've often thought that the speed-up was a stable acceleration from the dawn of time to the present."

"All right, go technical on me," laughed Walt. "Things do move. That is, all except the message from your loving husband."

"I doubt it. Squelching Donald Channing is a job for a superbeing. And I'm not too sure that a superbeing could squelch Don and make him stay squelched. Better check on Mojave."

"Gosh, if Don missed the Ariadne and I've been shooting him all kinds of screwy 'types every hour on the hour; Walt, that'll keep him quiet for a long, long time."

"That wouldn't have been so bad. But if the big bum missed and was ashamed of it—that'll be the payoff. Whoa, there goes the 'type!"

Walt looked at his watch and checked the course constants of the Ariadne. He called the beam-control dome and asked for the man on the ship's beam.

"Sure," answered Benny. "According to the mechanical mind here, they've been on Mojave for twenty minutes."

Arden fretted and Walt stamped up and down the room during the long minutes necessary for the message to reach Terra and the answer to return. It came right on the tick of the clock:

Walt smiled in a grim fashion. "Help!" he said. "We go on and on for years and years with no trouble—and now we've lost the third ship in a row."

"They claim that those things always run in threes," said Arden. "What are we going to do?"

"I don't know. We'll have to do something. Funny, but the one reason we must do something is the same reason why something can be done."

"With Channing on the Ariadne, something can be done. I don't know what, but I'll bet you a new hat that Don will make it possible for us to detect the ship. There is not a doubt in my mind that if the ship is still space-worthy, we can narrow the possibilities down to a thin cone of space."

"Well," said Franks taking the fountain pen out of the holder on the desk and beginning to sketch on the blotter, "the course of the Ariadne is not a very crooked one, as courses go. It's a very shallow skew curve. Admitting the worst, collision, we can assume only one thing. If the meteor were small enough to leave the ship in a floating but undirigible condition, it would also be small enough to do nothing to the general direction of the ship. Anything else would make it useless to hunt, follow?"

"Therefore we may assume that the present position of the ship is within the volume of a cone made by the tangents of the outermost elements of the space curve that is the ship's course. We can take an eight-thousand-mile cylinder out of one place—for the origin of their trouble is between Mars and Terra and the 'shadow' of Terra in the cone will not contain the Ariadne."

"Might have passed close enough to Terra to throw her right into the 'shadow' of Terra by attraction," objected Arden.

"Yeah, you're right. O.K., so we can't take out that cylinder of space. And we add a sort of sidewise cone on to our original cone, a volume through which the ship might have passed after flying close enough to Terra to be deflected. I'll have the slipstick experts give a guess as to the probability of the Ariadne's course, and at the same time we'll suspend all incoming operations. I'm going to set up every kind of detector I can think of, and I don't want anything upsetting them."

"I dunno. They might have a betatron aboard. In that case we'll eventually get a blast of electrons that'll knock our front teeth out. Don may succeed in tinkering up some sort of electrostatic field. We can check the solar electrostatic field to about seven decimal places right here, and any deviation in the field to the tune of a couple of million electron volts at a distance of a hundred million miles will cause a distortion in the field that we can measure. We'll ply oscillating beams through the area of expectation and hope for an answering reflection, though I do not bank on that. We'll have men on the lookout for everything from smoke signals to helio. Don't worry too much, Arden, your husband is capable of doing something big enough to be heard. He's just the guy to do it."

"I want to make an electroscope. That's about the only way I'll know whether we are getting out with this cockeyed electron gun."

"We can tell from the meter that reads the beam current whether anything is going up the pipe," explained Channing. "But if we just build us a nice heavy duty charge—as shown by the electroscope—we'll be sure that the electrons are not going far. This is one case where no sign is good news."

"Good. And now have the bird on the telescope find Venus Equilateral. Have him set the 'scope angles to the figures here and then have him contact Darlange to have the ship slued around so that Venus Equilateral is on the cross hairs. That'll put us on a line with the station. A bundle of electrons of this magnitude will make a reading on any detectors that Walt can set up."

Hadley called the observation dome. "Tim," he said, giving a string of figures, "set your 'scope for these and then get Darlange to slue the crate around so that your cross hairs are on Venus Equilateral."

"O.K.," answered Tim. "That's going to be a job. This business of looking through a 'scope while dressed in a spacesuit is no fun. Here goes."

He called Darlange, and the communicator system permitted the men in the instrument room to hear his voice. "Dar," he said, "loop us around about forty-one degrees from driver 3."

Darlange laughed. "What do you think these things are, blocks and tackles? You mean: 'Compensate a degree on 2.'"

"You're the pilot. That's the ticket—and I don't care if you lift it on one hand. Can you nudge her just a red hair on 3?"

"Best I can do is a hair and a half," said Darlange. He gave driver 3 just a tiny, instantaneous surge.

"Then take it up two and back one and a half," laughed Tim. "Whoa, Nellie, you're on the beam."

"Okay, Dar, but you'll have to play monkey on a stick. I'll prime you for any moving so that you can correct immediately."

"At this point I think a short prayer would be of assistance," said Channing soberly. "We're shooting our whole wad right now."

He closed the switch, and the power demand meters jumped up across their scales. The gold leaf electroscope jumped once; the ultra-thin leaves jerked apart by an inch, and then oscillated stiffly until they came to a balance. Channing, who had been looking at them, breathed deeply and smiled.

"No need," said Channing. "They know we're in the grease. We know that if they can collect us, they'll be on their way. I'm going to send out for a half-hour, and then resort to a five-minute transmission every fifteen minutes. They'll get a ship after us with just about everything we're liable to need, and they can use the five-minute transmissions for direction finding. The initial shot will serve to give them an idea as to our direction. All we can do now is to wait."

Electrically, Venus Equilateral was more silent than it had ever been. Not an electrical appliance was running on the whole station. People were cautioned about walking on deep-pile rugs, or combing their hair with plastic combs, or doing anything that would set up any kind of electronic charge. Only the highly filtered generators in the power rooms were running and these had been shielded and filtered long years before; nothing would emerge from them to interrupt the ether. All incoming signals were stopped.

And the men who listened with straining ears claimed that the sky was absolutely clear save for a faint crackle of cosmic static which they knew came from the corona of the Sun.

One group of men sat about a static-field indicator and cursed the minute wiggling of the meter, caused by the ever moving celestial bodies and their electronic discharges. A sunspot emission passed through the station once, and though it was but a brief passage, it sent the electrostatic field crazy and made the men jump.

The men who were straining their ears to hear became nervous and were jumping at every loud crackle.

And though the man at the telescope knew that his probability of picking up a sight of the Ariadne was as slender as a spider's web, he continued to search the starry heavens. He swept the narrow cone of the heavens wherein the Ariadne was lost according to the mathematical experts, and he looked at every bit of brightness in the field of his telescope as though it might be the missing ship.

The beam-scanners watched their return-plates closely. It was difficult because the receiver gains were set to maximum and every tick of static caused brief flashes of light upon their plates. They would jump at such a flash and hope for it to reappear on the next swipe, for a continuous spot of light would indicate the ship they sought. Then, as the spot did not reappear, they would go on with their beams to cover another infinitesimal portion of the sky. Moving forward across the cone of expectancy bit by bit, they crossed and recrossed until they were growing restive.

At the south end landing stage, a group of men were busy stocking a ship. Supplies and necessities were carried aboard, while another group of men tinkered with the electrical equipment. They cleared a big space in the observation dome, and began to install a replica of the equipment used on the station for detection. No matter what kind of output Channing sent back, they would be able to follow it to the bitter end.

They made their installations in duplicate, with one piece of each equipment on opposite sides of the blunt dome. Balancing the inputs of each kind by turning the entire ship would give them an indication of direction.

Franks did not hope that the entire installation could be completed before the signal came, but he was trying to outguess himself by putting some of everything aboard. When and if it came, he would be either completely ready with everything or he at least would have a good start on any one of the number of detectors. If need be, the detecting equipment in the station itself could be removed and used to complete the mobile installation.

Everything was in a complete state of nervous expectancy. Watchers watched, meter readers squinted for the barest wiggle, audio observers listened, trying to filter any kind of man-made note out of the irregular crackle that came in.

And the station announcing equipment was dead quiet, to be used only in case of emergency or to announce the first glimmer of radiation, whether it be material, electrical, kinetic, potential, or wave front.

There were mingled cheers and laughter as the speaker system broke away from babel, and each group spoke its piece with no interference. Walt Franks left the ship at the south end and raced to the beam control dome, just as fast as the runway car would take him. He ran into the dome in spacesuit and flipped the helmet back over his shoulder, "What kind of indication?" he yelled.

Charles Thomas, who had been busy with the electrostatic field indicator said: "I think maybe he's using some sort of electron gun—like the one you tried first off on the meteor destroyer job, remember?"

"Yeah, but that one wouldn't work—unless Don has succeeded in doing something we couldn't do. Look, Chuck, we haven't had time to set up a complete field indicator on the ship—grab yours and give the boys a lift installing it, hey?"

"Look for yourself," said the man on the beam scanner. "The whole plate is shining. We can't get a fix on them this way—they're radiating themselves and that means our scanner-system finder is worthless."

"We can, but it's rough," offered one of the radio men. "It came from an area out beyond Terra—and as for our readings it might have covered a quarter of the sky."

"The field indicator is a short-base finder," explained Thomas. "And no less rough than the radio boys. I'd say it was out beyond Terra by fifty million miles at least."

"Close enough. We'll have to track 'em down like a radio equipped bloodhound. Chuck, come along and run that mechanico-electro-monstrosity of yours. Gene, you can come along and run the radio finder. Oh, yes, you, Jimmy, may continue to squint through that eyepiece of yours—but on the Relay Girl. We need a good, first-class squinter, and you should have an opportunity to help."

Jimmy laughed shortly. "The only guy on the station that didn't get an indication was me. Not even a glimmer."

"Channing didn't know we'd be looking for him, or he'd probably light a flare, too. Cheer up, Jimmy, after all this crude, electrical rigmarole is finished, and we gotta get right down to the last millimeter, it's the guy with the eye that polishes up the job. You'll have your turn."

Twenty minutes after the first glimmer of intelligent signal, the Relay Girl lifted from the south end and darted off at an angle, setting her nose roughly in the direction of the signal.

Her holds were filled with spare batteries and a whole dozen replacement cathodes, as well as her own replacements. Her crew was filled to the eyebrows with gravanol, and there must have been a mile of adhesive tape and cotton on their abdomens. At six G she left, and at six G she ran, her crew immobilized but awake because of the gravanol. And though the acceleration was terrific, the tape kept the body from folding of its own weight. When they returned, they would all be in the hospital for a week, but their friends would be with them.

Walt said: "Keep her running. Don's saving electricity. Tell me when we pick him up again."

Franklen, the pilot, nodded. "We haven't got a good start yet. It'll be touch and go. According to the slipstick boys, they must be clapping it up at between twenty-five hundred and five thousand miles per second to get that far—and coasting free or nearly so. Otherwise they'd have come in. Any suggestions as to course?"

"Sure. Whoop it up at six until we hit about six thousand. Then decelerate to four thousand by using one G. We'll vacillate in velocity between four and five until we get close."

Channing said to Captain Johannson: "Better cut the decel to about a quarter G. That'll be enough to keep our heads from bumping the ceiling, and it will last longer. This is going to be a long chase, and cutting down a few MPS at a half G isn't going to make much never-mind. I'll hazard a guess that the boys are on their way right now."

"If you say so," said Johannson. "You're the boss from now on. You know that wild bunch on the station better than I do. For myself, I've always felt that an answer was desirable before we do anything."

"I know Franks and my wife pretty well—about as well as they know me. I've put myself in Walt's place—and I know what Walt would do. So—if Walt didn't think of it, Arden would—I can assume that they are aware of us, have received our signals, and are, therefore, coming along as fast as they can. They'll come zipping out here at from five to seven G to what they think is halfway and then decelerate again to a sane velocity. We won't catch sight of them for sixty or seventy hours, and when we do, they'll be going so fast that it will take another twenty hours' worth of manipulation to match their speed with ours. Meanwhile, I've got the gun timed to shoot our signal. When the going gets critical, I'll cut the power and make it continuous."

"Well, the best they can do as for direction and velocity and distance is a crude guess. They'll place us out here beyond Terra somewhere. They'll calculate the course requirements to get us this far in the time allotted, and come to a crude figure. I'd like to try keying this thing, but I know that keying it won't work worth a hoot at this distance. Each bundle of keyed electrons would act as a separate negative charge that would spread out and close up at this distance. It's tough enough to hope that the electron beam will hold together that far, let alone trying to key intelligence with it. We'll leave well enough alone—and especially if they're trying to get a fix on us; there's nothing worse than trying to fix an intermittent station. Where are we now?"

"We're on the inner fringe of the Asteroid Belt, about thirty million miles north, and heading on a secant course at thirty-four hundred MPS."

"Too bad Jupiter isn't in the neighborhood," said Channing. "We'll be flirting with his orbit by the time they catch us."

"Easily," said Johannson. "In sixty hours, we'll have covered about six hundred and fifty million miles. We'll be nearer the orbit of Saturn, in spite of the secant course."

"Your secant approaches a radius as you get farther out," said Don, absently. "As far as distances go, Titan, here we come!"

"Pretty well," said Doc. "There's as pretty an assortment of fractured limbs, broken ribs, cracked clavicles, and scars, mars, and abrasions as you ever saw. There are a number dead, worse luck, but we can't do a thing about them. We can hold on for a week as far as food and water goes. Everyone is now interested in the manner of our rescue rather than worrying about it." He turned to Channing. "The words Channing and Venus Equilateral have wonderful healing powers," he said. "They all think your gang are part magician and part sorcerer."

"I didn't ask. Once I told 'em you had a scheme to contact the relay station, they were all satisfied that things would happen for the better."

"I think not," answered Doc. "What I said before still goes. Your job is to bring aid—and that's the sum total of your job. Every effort must be expended on that and that alone. You've got too many whole people depending on you to spend one second on the hurt. That's my job."

"I hope we're not complicating the job of finding us by this quartering deceleration," said Captain Johannson.

"We're not. We're making a sort of vector from our course, but the deviation is very small. As long as the fellows follow our radiation, we'll be found," Channing said with a smile. "The thing that is tough is the fact that all the floors seem to lean over."

"They wouldn't lean at all if we were running with the whole set of equipment," said Darlange. "We run a complete turnover without spilling a drop from the swimming pool."

"Stop worrying about it," said Doc. "I'm the only guy who has to worry about it and as long as the floor is still a floor, I can stand sliding into the corner once in a while."

"We might tinker with the turnover drivers," offered Don. "We can bring 'em down to a place where the velocity-deceleration vectors are perpendicular to the floor upon which we stand while our ship is sluing. We've got a lot of time on our hands, and I, for one, feel a lot happier when I'm doing something."

Thirty hours after the Relay Girl left the station, Walt and Franklen held a council of war, in which Chuck Thomas was the prime factor.

"We've come about two hundred million miles, and our present velocity is something like four thousand miles per second," said Walt. "We're going out toward Mars on a slightly-off radial course, to the north of the ecliptic. That means we're a little over a quarter of a billion miles from Sol, or about to hit the Asteroid Belt. Thinking it over a little, I think we should continue our acceleration for another thirty hours. What say?"

"The field has shown no change in intensity that I can detect," said Thomas. "If they haven't dropped their radiated intensity, that means that we are no closer to them than we were before. Of course, we'd probably have to cut the distance by at least a half before any measurable decrement made itself evident."

"They must be on the upper limit of that four thousand MPS," observed Walt. "There's one thing certain, we'll never catch them by matching their speed."

"By about thirty percent," said Walt, scratching his chin. "If we hold to our original idea of hitting it for six thousand, where will we be?"

"That would make it about forty-five hours from take-off, and we'd be about four hundred and sixty million miles from Sol." Chuck grinned widely and said: "By Jove!"

"Sure will after that. So then we'll be 'By Jove' at six thousand. That would be a swell place to make turnover, I think. At one G decel to about four thousand MPS that'll put us about—um, that'd take us about ninety hours! We'll make that three G at twenty hours, which will put us about three hundred and fifty million miles along, which plus the original four hundred and sixty million adds up to eight hundred and ten million—"

"When an astronaut begins to talk like that," interrupted Arden, "we of the skyways say that he is talking in Congressional figures. The shoe is on the other foot. What on earth are you fellows figuring?"

"Where we'll be and how fast we'll be going at a given instant of particular importance," offered Walt. "When did you wake up?"

"About the third hundred million. All of those ciphers going by made a hollow sound, like a bullet whistling in the wind."

"Well, we're trying to make the theories of probability match with figures. We'll know in about forty-five hours whether we were right or not."

"It's a good thing we have all space to go around in. Are you sure that we have all eternity?"

"Don't get anxious. They're still coming in like a ton of bricks four times per hour, which means that they're riding easy. I don't want to overrun them at about three thousand MPS and have to spend a week decelerating, returning, more decelerating, and then matching velocities."

"I see. You know best. And where is this Asteroid Belt that I've heard so much about?"

"To the south of us by a few million miles. Those bright specks that you can't tell from stars are asteroids. The common conception of the Asteroid Belt being filled to overflowing with a collection of cosmic rubble like the rings of Saturn is a lot of hooey. We'll be past in a little while and we haven't even come close to one. Space is large enough for all of us, I think."

"I don't care for their area," said Walt with a smile. "Let 'em have it, I don't care. I'll stay up here and let them run as they will."

"Those are asteroids, yes. We're to the north, as you may check by going around the ship to the opposite side. You'll see Polaris almost directly opposite, there. Sol is almost directly below us, and that bright one that you can see if you squint almost straight up is Saturn."

"I won't bother crossing the ship to see Polaris. I prefer the Southern Cross, anyway. The thing I'm most interested in is: Are we accomplishing anything?"

"I think that we've spent the last thirty hours just catching up," explained Walt. "Up to right now, we are going backwards, so to speak; we're on even terms now, and will be doing better from here on in."

"Let's eat," suggested Walt. "I'm hungry, and now that I think of it, I haven't eaten since we left the station. Arden, you are hereby elected to the post of galley chief. Get Jimmy from the dome if you need help."

"That's hearsay, I'll show you! As soon as I find the can opener, breakfast will be served."

"O.K., we will have a combined meal, from grapefruit to ice cream. Those who want any or all parts may choose at will. And fellows, please let me know as soon as you get something tangible."

"That's a promise," said Walt. "Take it easy, and don't worry. We'll be catching up with them one of these days."

"Not too much. We had about twenty G hours to begin with. We went to a half G for twenty hours, and now we're running on a quarter G, which would let us go for forty hours more."

"Well, look. If it should come to a choice between floor and signal gun, we'll choose the gun. We've about eight hours left in the cathodes, and since everybody is now used to quarter G we might even slide it down to an eighth G, which would give us about sixteen hours."

"So far as I can tell. Six hours from now, we should know, I think, predicating my guess on whatever meager information they must have."

"That's a thought. Johannson, have one of your men run around and remove all lights that aren't absolutely necessary. He can kill about three-quarters of them, I'm certain. That'll save us a few kilowatt hours," said Channing. "And another thing. I'm about to drop the power of our electron gun and run it continuously. If the boys are anywhere in the neighborhood, they'll be needing continuous disturbance for direction finding. I'd say in another five hours that we should start continuous radiation."

"You know, Channing, if this thing works out all right, it will be a definite vote for pure, deductive reasoning."

"I know. But the deductive reasoning is not too pure. It isn't guesswork. There are two factors of known quality. One is that I know Walt Franks and the other is that he knows me. The rest is a simple matter of the boys on the station knowing space to the last inch, and applying the theory of probabilities to it. We'll hear from them soon, or I'll miss my guess. Just you wait."

Chuck Thomas made another computation and said: "Well, Walt, we've been narrowing them down for quite a long time now. We're getting closer and closer to them, according to the field intensity. I've just got a good idea of direction on that last five minute shot. Have Franklen swivel us around on this course; pretty soon we'll be right in the middle of their shots."

"We're approaching them asymptotically," observed Walt. "I wish I knew what our velocity was with respect to theirs. Something tells me that it would be much simpler if I knew."

"You mean how far? Well, I don't know that it has ever been tried and recorded. But we can figure it out easy enough by analogy. A period is about thirty-thousandths of an inch in diameter, and visible from a distance of thirty inches. I mean visible with no doubt about its being there. That's a thousand to one. Now, the Ariadne is about six hundred feet tall and about four hundred feet in its major diameter, so we can assume a little more than the four hundred feet—say five hundred feet average of circular area, say—follow me?"

"Then at a thousand to one, that becomes five hundred thousand feet, and dividing by five thousand—round figures because it isn't important enough to use that two hundred and eighty feet over the five thousand—gives us one thousand miles. We should be able to see the Ariadne from a distance of a thousand miles."

"Then at four thousand miles per second we'll be in and through and out of visual range in a half second?"

"Oh, no. They're rambling on a quite similar course at an unknown but high velocity. Our velocity with respect to theirs is what will determine how long they're within visual range."

"Hey, Walt," came the voice of Chuck Thomas. "The intensity of Don's beam has been cut to about one-quarter and is now continuous. Does that mean anything?"

"Might mean trouble for them. Either they're running out of soup and mean for us to hurry up, or they assume we're close enough to obviate the need for high power. We'd better assume they want haste and act accordingly. How're the boys on the radio detectors coming along?"

"Fine. They've taken over the direction finding and claim that we are right on their tail."

"Not yet. But the electroscope boys claim that quarter power or not, the input is terrific."

"Take a rest, Jimmy. We won't be there for a while yet. No use burning your eyes out trying to see 'em. There'll be time enough for you to do your share after we get 'em close enough to see with the naked eye. What do the beam-scanners say?"

"Shucks," answered the man on the scanners, "they're still radiating. How are we going to fix 'em on a reflected wave when they're more powerful on their own hook? The whole plate is glaring white. And, incidentally, so is the celestial globe in the meteor spotter. I've had to cut that or we'd never be able to hold this course. Anything like a meteor that comes in our way now will not register, and—"

The Relay Girl lurched sickeningly. All over the ship, things rattled and fell to the floors. Men grabbed at the closest solid object, and then the Relay Girl straightened out once more.

"Franklen, hang on about seven G and follow Jimmy's orders. Chuck, see if you can get anything cogent out of your gadget. Holy Green Fire, with a cubic million million million megaparsecs in which to run, we have to be so good that we run right into our quarry. Who says that radio direction finding is not a precise science? Who says that we couldn't catch—"

"O.K., Jimmy, can you give me any idea as to their velocity with respect to ours?"

Jimmy was silent for some seconds, "They're out of sight again, but I make it about four to seven hundred miles per second."

"No," said Walt. "I used the max figure and we can assume they aren't going that fast, quite. At the end of four hours, we'll turnover and wait until they heave in sight again and then we'll do some more oscillating. We can match their velocity inside of ten hours, or Franklen will get fired."

"We are!" called the radio man. "It's Channing. He says: 'Fancy meeting you here.' Any answer?"

Channing's voice came out of the ship's announcer system as the radio man made the necessary connections. It said: "Right—but what kept you so long?"

"Some boss. Some crew of wild men. Can't go off on a fishing trip without having my bunch chasing all over the Solar System."

"What's wrong with a little sight-seeing tour? We didn't mean any harm. And speaking of harm, how are you and the rest of that bunch getting along?"

"We're O.K. What do you plan after we finally get close enough together to throw stones across?"

"We've got a whole hold full of spare batteries and a double set of replacement cathodes. There is a shipload of gravanol aboard, too. You'll need that and so will we. By the time we finish this jaunt, we'll have been about as far out as anybody ever gets."

"Yeah—got any precise figures? We've been running on a guess and a hope. I make it about seven hundred million."

"Make it eight and a half. At six G you'll cover another hundred and fifty million miles before you stop. Take it twenty-two hours at six G—and then another twenty-two at six. That should put you right back here but going the other way at the same velocity. But wait, you've been coasting. Mark off that last twenty-two hours and make it like this: You'll be one thousand million miles from Sol when you come to a stop at the end of the first twenty-two hours at six G. That hangs you out beyond the orbit of Saturn by a couple of hundred million. Make it back forty-four hours at six G, turnover and continue. By that time we'll all be in so close that we can make any planet at will—preferably you to Terra and we'll head for Venus Equilateral. You'll come aboard us? No need for you to go with the rest."

"Don't you 'But Arden' me, you big gadabout. Glad to see you! Boy, any man that makes me chase him all over the Solar System! You just wait. As soon as I get ahold of you, Don Channing, I'm going to—to bust out and bawl like a kid! Hurry up, willya?"

Interlude:

Six thousand years ago, Sargon of Akkad held court on the plains of Assyria by torchlight. Above his head there shone the myriad of stars, placed there to increase his power and glory.

But on one of the stars above called Mars, there were people who knew a mighty civilization and a vast world of science. They flew above the thin air of Mars and they hurled power by energy beam across the face of the planet.

Then they—died. They died, and they left but broken fragments of their once-mighty civilization buried in the shifting, dusty sands of Mars. Long centuries afterwards, man crossed space to find these fragments and wonder.

How or why they died is a matter of conjecture. It is known that iron is the most stable of all known atomic structures besides helium. It is also known that the surface of Mars has its characteristic reddish hue because of the preponderance of iron compounds there. From the few remaining artifacts, it is known that Mars exceeded the present Terran science, which includes atomic power. The inference is that Mars died completely in the horror of atomic war.

This is but reasoning. The facts that are of interest include the finding of a gigantic vacuum tube fastened to a shattered steel tower in the sands between Canalopsis and Lincoln Head, Mars.

The original finders, Martian archeologists Baler and Carroll, were versed enough in electronics to make tests. They discovered many interesting facts about this tube before they sold it to Terran Electric for a monumental sum of money. Their reasons for selling the thing were simple. They preferred digging in the sands of Mars to plunging into the depths of a highly technical manufacturing business, and the money was more than adequate.

Don Channing's main objection was that Carroll and Baler did not consult Venus Equilateral before they disposed of their find.

That made it necessary for Venus Equilateral to acquire a tube for their research by dealing with Terran Electric, which in this case was similar to obtaining a ton of uranium ore from Oak Ridge back in the year 1945. Often, of course, the shortest distance home is...

THE LONG WAY

Don Channing stood back and admired his latest acquisition with all of the fervency of a high school girl inspecting her first party dress. It was so apparent, this affection between man and gadget, that the workmen who were now carrying off the remnants of the packing case did so from the far side of the bench so that they would not come between the Director of Communications and the object of his affection. So intent was Channing to the adoration of the object that he did not hear the door open, nor the click of high heels against the plastic flooring. He was completely unaware of his surroundings until Arden said:

"Jilted for a jimcrank," groaned Arden. "Tell me, my quondam husband, what is it?"

"How do you do?" said Arden to the big tube. "Funny looking thing, not like any transmitting tube I've ever seen before."

"Not a transmitting tube," explained Channing. "It is one of those power transmission tubes that Baler and Carroll found on the Martian Desert."

Channing laughed. "Not the one found—there was only one found. This is a carbon copy. They are going to revolutionize the transmission of power with them."

"Not too much. But I've got Barney Carroll coming out here and a couple of guys from Terran Electric. I'm going to strain myself to keep from tinkering with the thing until they get here."

"I know," said Channing. "But the Terran Electric boys have sewed up the rights to this dingus so tight that it is squeaking. Seems to be some objection to working on them in the absence of their men."

"Probably because Terran Electric knows a good thing when they see it. Barney's latest 'gram said that they were very reluctant to lend this tube to us. Legally they couldn't refuse, but they know darned well that we're not going to run power in here from Terra—or anywhere else. They know we want it for experimentation, and they feel that it is their tube and that if any experimentation is going to take place, they're going to do it."

The workmen returned with two smaller cases; one each they placed on benches to either side of the big tube. They knocked the boxes apart and there emerged two smaller editions of the center tube—and even Arden could see that these two were quite like the forward half and the latter half, respectively, of the larger tube.

"Sure. This one on the left is the input-terminal tube which they call the power-end. The good old D.C. goes in across these big terminals. It emerges from the big end, here, and bats across in a beam of intangible something-or-other until it gets to the relay tube, where it is once more tossed across to the load-end tube. The power is taken from these terminals on the back end of the load-end tube and is then suitable for running motors, refrigerators, and so on. The total line-loss is slightly more than the old-fashioned transmission line. The cathode-dynode requires replacements about once a year. The advantages over high-tension wires are many; in spite of the slightly-higher line-losses, they are replacing long-lines everywhere.

"When they're properly aligned they will arch right over a mountain of solid iron without attenuation. It takes one tower every hundred and seventy miles, and the only restriction on tower height is that the tube must be above ground by ten to one the distance that could be flashed over under high intensity ultraviolet light."

"Well, high tension juice will flash over better under ultraviolet illumination. The tube must be high enough to exceed this distance by ten to one at the operating voltage of the stuff down the line. The boys in the Palanortis Jungles say they're a godsend, since there are a lot of places where the high tension towers would be impossible since the Palanortis Whitewood grows about a thousand feet tall."

"You'd cut a lot of wood to ream a path through from Northern Landing to the power station on the Boiling River," said Arden.

"Yeah," drawled Don, "and towers a couple of hundred miles apart are better than two thousand feet. Yeah, these things are the nuts for getting power shipped across country."

"Couldn't we squirt it out from Terra?" asked Arden. "That would take the curse off of our operating expenses."

"It sure would," agreed Channing heartily. "But think of the trouble in aligning a beam of that distance. I don't know—there's this two hundred miles' restriction, you know. They don't transmit worth a hoot over that distance, and it would be utterly impossible to maintain stations in space a couple of hundred miles apart, even from Venus, from which we maintain a fairly close tolerance. We might try a hooting big one, but the trouble is that misalignment of the things result in terrible effects."

"Take a good look at 'em," said Channing. "Might make some working X-ray plates, too. It was a lucky day that these got here before the boys from Terran Electric. I doubt that they'd permit that."

"O.K.," said Chuck, "I'll bring the X-ray up here and make some pix. We'll want working prints; Warren will have to take 'em and hang dimensions on to fit."

"And we," said Channing to Walt Franks, "will go to our respective offices and wait until the Terran Electric representatives get here."

The ship that came with the tubes took off from the landing stage, and as it passed their observation dome, it caught Don's eye. "There goes our project for the week," he said.

"He's been like that ever since we tracked him down on the Ariadne," said Arden.

"Project for the week?" asked Walt. "Brother, we've been tinkering with that idea for months, now."

"Well," said Don, "there goes four drivers, all batting out umpty-ump begawatts of something. They can hang a couple of G on a six hundred foot hull for hours and hours. The radiation they emit must be detectable; don't tell me that such power is not."

"The interplanetary companies have been tinkering with drivers for years and years," said Walt. "They have never detected it?"

"Could be, but there are a couple of facts that I'd like to point out. One is that they're not interested in detection. They only want the best in driver efficiency. Another thing is that the radiation from the drivers is sufficient to ionize atmosphere into a dull red glow that persists for several minutes. Next item is the fact that we on Venus Equilateral should be able to invent a detector; we've been tinkering with detectors long enough. Oh, I'll admit that it is secondary-electronics—"

"It isn't electronics," said Channing. "It's sub-etheric or something like that. We'll call it subelectronics for lack of anything else. But we should be able to detect it somehow."

"Is it?" interrupted Arden with a smile. "What happens to radiation when intercepted?"

"That takes care of the radiation output," said Arden. "Now, how about electrical losses?"

"Then everything that goes into an electric heater emerges as heat," said Arden.

"I get it," laughed Walt. "Efficiency depends on what you hope to get. If what you want is losses, anything that is a total loss is one hundred percent efficient. Set your machine up to waste power and it becomes one hundred percent efficient as long as there is nothing coming from the machine that doesn't count as waste."

"Fine point for arguing," smiled Channing. "But anything that will make atmosphere glow dull red after the passage of a ship will have enough waste to detect. Don't tell me that the red glow enhances the drive."

The door opened again and Chuck Thomas came in with a crew of men. They ignored the three, and started to hang heavy cloth around the walls and ceiling. Chuck watched the installation of the barrier-cloth, and then said: "Beat it—if you want any young Channings!"

The tall, slender man handed Don an envelope full of credentials. "I'm Wesley Farrell," he said. "Glad to have a chance to work out here with you fellows."

"How do you do?" said Channing. Kingman did not impress Channing as being a person whose presence in a gathering would be demanded with gracious shouts of glee.

"My purpose," said Kingman, "is to represent my company's interest in the transmission tube."

"Messrs. Baler and Carroll sold their discovery to Terran Electric outright. We have an iron-bound patent on the device and/or any developments of the device. We hold absolute control over the transmission tube, and therefore may dictate all terms on which it is to be used."

"I understand. You know, of course, that our interest in the transmission tube is purely academic."

"I have been told that. We're not too certain that we approve. Our laboratories are capable of any investigation you may desire, and we prefer that such investigations be conducted under our supervision."

"Naturally," said Kingman in a parsimonious manner. "But should you develop a new use for the device, we shall have to demand that we have complete rights."

"Not at all. I am a lawyer, not an engineer. Dr. Farrell will take care of the technical aspects of the device."

"Daily reports from your group. Daily conferences with your legal department. These reports should be prepared prior to the day's work so that I may discuss with the legal department the right of Terran Electric to permit or disapprove the acts."

"You understand that there may be a lot of times when something discovered at ten o'clock may change the entire program by ten oh six?"

"That may be," said Kingman, "but my original statements must be adhered to, otherwise I am authorized to remove the devices from your possession. I will go this far, however; if you discover something that will change your program for the day, I will then call an immediate conference which should hurry your program instead of waiting until the following morning for the decision."

"Thanks," said Channing dryly. "First, may we take X-ray prints of the devices?"

"No. Terran Electric will furnish you with blueprints which we consider suitable." Kingman paused for a moment. "I shall expect the complete program of tomorrow's experiments by five o'clock this evening."

Kingman left, and Wes Farrell smiled uncertainly. "Shall we begin making the list?"

"Might as well," said Channing. "But, how do you lay out a complete experimental program for twelve hours ahead?"

"I wonder if it might not be desirable for Kingman to sit in on these program-settings?" said Channing, after a moment of staring at the page before him.

Walt came in on the last words. Channing brought Franks up to date and Walt said: "But why should he want a written program if he's going to disallow certain ideas?"

"Sounds to me like he's perfectly willing to let us suggest certain lines of endeavor; he may decide that they look good enough to have the Terran Electric labs try themselves," said Channing.

"I have half a notion to toss him out," Channing told Farrell. "I also have half a notion to make miniatures of this tube and go ahead and work regardless of Kingman or Terran Electric. O.K., Wes, we won't do anything illegal. We'll begin by making our list."

"We hope that these tubes will enable us to detect driver radiation, which will ultimately permit us to open ship-to-ship two-way communication."

"Sure. We're going to cut and try. No one knows a thing about the level of driver-energy; we've selected a name for it: Subelectronics. The driver tube is akin to this transmission tube, if what I've been able to collect on the subject is authentic. By using the transmission tube—"

"Your belief is interesting. I've failed to see any connection between our tube and the driver tube."

"Oh, sure," said Channing expansively. "I'll admit that the similarity is of the same order as the similarity between an incandescent lamp and a ten dynode electron-multiplier such as we use in our final beam stages. But recall this business of the cathode-dynode. In both, the emitting surface is bombarded by electrons from electron guns. They both require changing."

"I know that, but the driver cathode disintegrates at a rate of loss that is terrific compared to the loss of emitting surface in the transmission tube."

"The driver cathode is worth about two hundred G-hours. But remember, there is no input to the driver such as you have in the transmission tube. The power from the driver comes from the disintegration of the cathode surface—there isn't a ten-thousandth of an inch of plating on the inside of the tube to show where it went. But the transmission tube has an input and the tube itself merely transduces this power to some level of radiation for transmission. It is re-transduced again for use. But the thing is this: your tube is the only thing that we know of that will accept sub-electronic energy and use it. If the driver and the transmission tubes are similar in operational spectrum, we may be able to detect driver radiation by some modification."

"Yeah," drawled Farrell, "but could you stand by and watch me work on a beam transmitter?"

"Then don't expect me to watch without getting my fingers dirty," said Farrell cheerfully. "Sitting around in a place like this would drive me nuts without something to do."

"O.K., then," smiled Don. "We'll start off by building about a dozen miniatures. We'll make 'em about six inches long—we're not going to handle much power, you know. That's first."

Kingman viewed the list with distaste. "There are a number of items here which I may not allow," he said.

"One, the manufacture or fabrication of power transmission tubes by anyone except Terran Electric is forbidden. Two, your purpose in wanting to make tubes is not clearly set forth. Three, the circuit in which you intend to use these tubes is unorthodox, and must be clearly and fully drawn and listed."

"Oh, spinach! How can we list and draw a circuit that is still in the embryonic stage?"

"I am beginning to believe that your research department has not the ability to reduce your problems to a precise science," said Kingman coldly.

"The legal trade is as precise as any. Everything we do is done according to legal precedent."

"But I've got to show you a complete circuit before you'll permit me to go ahead?"

"That's not all. Your program must not include reproducing these tubes either in miniature or in full size—or larger. Give me your requirements and I shall request Terran Electric to perform the fabrication."

"Look, Kingman, Venus Equilateral has facilities to build as good a tube as Terran Electric. I might even say better, since our business includes the use, maintenance, and development of radio tubes; your tubes are not too different from ours. Plus the fact that we can whack out six in one day, whilst it will take seventy-three hours to get 'em here after they're built on Terra."

"I'm sorry, but the legal meaning of the patent is clear. Where is your legal department?"

"I'll request you to have a legal representative come to the station so that I may confer with him. One with power of attorney to act for you."

"Sorry," said Channing coldly. "I wouldn't permit any attorney to act without my supervision."

"That's rather a backward attitude," said Kingman. "I shall still insist on conducting my business with one of legal mind."

"O.K. We'll have Peterman come out from Terra. But he'll still be under my supervision."

"As you wish, I may still exert my prerogative and remove the tubes from your possession."

"Oh, no, it won't be. You may enter the laboratory at any time and remove the tubes. Of course, if you are without technical training you may find it most difficult to disconnect the tubes without getting across a few thousand volts. That might be uncomfortable."

"Are you threatening me?" said Kingman, bristling. His stocky frame didn't take to bristling very well, and he lost considerable prestige in the act.

"Not at all, I'm just issuing a fair warning that the signs that say: 'DANGER! HIGH-VOLTAGE!' are not there for appearance."

"Have I threatened you? It sounds to me as though I were more than anxious for your welfare. Any threat of which you speak is utterly without grounds, and is a figment of your imagination; based upon distrust of Venus Equilateral, and the personnel of Venus Equilateral Relay Station."

Kingman shut up. He went down the list, marking off items here and there. While he was marking, Channing scribbled a circuit and listed the parts. He handed it over as Kingman finished.

"I shall be happy to present you with a book on essential radio technique," offered Channing. "A perusal of which will place you in possession of considerable knowledge. Will that suffice?"

"I believe so. I cannot understand how; being uncertain of your steps a few minutes ago, you are now presenting me with a circuit of your intended experiment."

"The circuit is, of course, merely symbolic. We shall change many of the constants before the day is over—in fact, we may even change the circuit."

"I shall require a notice before each change so that I may pass upon the legal aspects."

"Walt," said Don, "will you accompany me to a transparency experiment on the Ninth Level?"

They left the office quickly, and started for Joe's. They had not reached the combined liquor vending and restaurant establishment when the communicator called for Channing. It was announcing the arrival of Barney Carroll, so instead of heading for Joe's, they went to the landing stage at the south end of the station to greet the Visitor.

"Barney," said Don, "of all the companies, why did you pick on Terran Electric?"

"Well, Jim and I couldn't handle anything as big as the power transmission set-up. They paid out a large slice of jack for the complete rights. All of us are well paid now. After all, I'm primarily interested in Martian artifacts, you know."

"Probably. And, no doubt, the legals had a lot to do with the fall of the Martian civilization."

"As it will probably get this one so wound up with red tape that progress will be impossible—or impractical."

"Well, Barney, let's take a run up to the lab. We can make paper-talk even if Brother Kingman won't let us set it to soldering iron. There are a lot of things I want to ask you about the tube."

They sat around a drawing table and Channing began to sketch. "What I'd hoped to do is this," he said, drawing a schematic design. "We're not interested in power transmission, but your gadget will do a bit of voltage amplification because of its utter indifference to the power-line problem of impedance matching. We can take a relay tube and put in ten watts, say, across ten thousand ohms. That means the input will be somewhat above three hundred volts. Now, if our output is across a hundred thousand ohms, ten watts will give us one thousand volts. So we can get voltage amplification at the expense of current—which we will not need. Unfortunately, the relay tube as well as the rest of the system will give out with the same kind of power that it is impressed with—so we'll have amplification of driver radiation. Then we'll need a detector. We haven't been able to get one either yet, but this is a start, providing that Terran Electric will permit us to take a deep breath without wanting to pass on it."

"I think you may be able to get amplification," said Barney. "But to do it, you'll have to detect it first."

"Sure. Before these darned things will work, this in-phase anode must be right on the beam. That means that you'll require a feedback circuit from the final stage to feed the in-phase anodes. Could be done without detection, I suppose."

"Well, for one thing, we're going to get some amplification if we change the primary anode—so. That won't permit the thing to handle any power, but it will isolate the output from the input and permit more amplifications. Follow?"

"Yeah," said Don to Barney, "now you'll see the kind of birds you sold your gadget to."

They found Kingman and Farrell in conference. Channing offered his suggestion immediately, and Kingman looked it over, shaking his head.

"It is not permitted to alter, change, rework, or repair tubes owned by Terran Electric," he said.

"Give me your recommendation and I shall have the shop at Terran Electric perform the operation."

"Cost plus a slight profit. Terran Electric, just as Venus Equilateral, is not in business from an altruistic standpoint."

"Also," said Kingman severely, "I noticed one of your men changing the circuit slightly without permission. Why?"

"Charles Thomas is in charge of development work," said Channing. "He probably noted some slight effect that he wanted to check."

"He should have notified me first—I don't care how minute the change. I must pass on changes first."

Channing looked at Farrell critically. The Terran Electric engineer seemed sincere, and the pained expression on his face looked like frustrated sympathy to Don. "Come along," he said.

Barney smiled cheerfully at the sign on Joe's door. "That's a good one, 'Best Bar in Twenty-seven Million Miles, Minimum!' What's the qualification for?"

"That's as close as Terra ever gets. Most of the time the nearest bar is at Northern Landing, Venus; sixty-seven million miles from here. Come on in and we'll get plastered."

Farrell said, "Look, fellows, I know how you feel. They didn't tell me that you weren't going to be given permission to work. I understood that I was to sort of walk along, offer suggestions and sort of prepare myself to take over some research myself. This is sickening."

"Fine. And may we pray that the redesign is good enough to make a difference to the Interplanetary Patent Office." Channing called Joe, "The same. Three Moons all around. Scotch," he explained to the others, "synthesized in the Palanortis Country."

Joe smiled. "They all have laboratories and draftsmen and textbooks," he said. "But for real engineering, they use my tablecloths. Three more problems and I'll have a complete tablecloth course in astrophysics, with a sideline in cartooning and a minor degree in mechanical engineering."

"Sure. Give 'em a free hand, and a couple of your tubes and a tablecloth and they'll have 'em frying eggs by morning. When I came out here, they demanded a commercial bond and I thought they were nuts. Who ever heard of making a restaurateur post a bond? I discovered that all of their inventions are initially tinkered out right here in the dining room—I could steal 'em blind if I were dishonest!" Joe smiled hugely. "This is the only place in the System where the tablecloths have been through blueprint machines. That," he said confidentially to Barney, "is why some of the stuff is slightly garbled. Scotch mixed with the drawings. They have the cloths inspected by the engineering department before they're laundered; I lose a lot of tablecloths that way."

The Three Moons came next, and then Don began to sketch. "Suppose we make a driver tube like this," he said. "And we couple the top end, where the cathode is, to the input side of the relay tube. Only the input side will require a variable-impedance anode, coupled back from the cathode to limit the input to the required value. Then the coupling anodes must be served with an automatic-coupling circuit so that the limiting power is passed without wastage."

Barney pulled out a pencil. "If you make that automatic-coupling circuit dependent upon the output from the terminal ends," he said, "it will accept only the amount of input that is required by the power being used from the output. Over-cooling these two anodes will inhibit the power-intake."

"Right," said Wes. "And I am of the opinion that the power available from Sol is of a magnitude that will permit operation over and above the limit."

"Four million tons of energy per second!" exploded Walt. "That's playing with fire!"

"Our experience with relay tubes," said Farrell slowly, "indicates that some increase in range is possible with additional anode-focussing. Build your tube-top with an extra set of anodes, and that'll give us better control of the beam."

"We're getting farther and farther from the subject of communications," said Channing with a smile. "But I think that we'll get more out of this."

"Until we get a chance to tinker with those tubes, we won't get ship-to-ship two ways. So we'll gadgeteer up something that will make Terran Electric foam at the mouth, and swap a hunk of it for full freedom in our investigations. Or should we bust Terran Electric wholeheartedly?"

"Go ahead," said Wes. "I'm utterly disgusted, though I think our trouble is due to the management of Terran Electric. They like legal tangles too much."

"We'll give 'em a legal tangle," said Barney. He was adding circuits to the tablecloth sketch.

Channing, on his side, was sketching in some equations, and Walt was working out some mechanical details. Joe came over, looked at the tablecloth, and forthright went to the telephone and called Warren. The mechanical designer came, and Channing looked up in surprise. "Hi," he said, "I was just about to call you."

Warren looked the thing over. "Give me about ten hours," he said. "We've got a spare turnover driver from the Relay Girl that we can hand-carve. There are a couple of water-boilers that we can strip, cut open, and make to serve as the top end. How're you hoping to maintain the vacuum?"

"Yes," said Wes Farrell, "that's going to be the problem. If there's any adjusting of electrodes to do, this'll take months."

"That's why we, on Venus Equilateral, are ahead of the whole ding-busted Solar System in tube development," said Don. "We'll run the thing out in the open—and I do mean open! Instead of the tube having the insides exhausted, the operators will have their envelopes served with fresh, canned air."

"Like a cartoon I saw somewhere," grinned Walt. "Had a bird in full armor tinkering with a radio set. The caption was: 'Why shield the set?'"

"Phooey," said Warren. "Look, Tom Swift, is this another of the Franks' brainchildren?"

"Yeah. That's the nom de plume he invents under. The other guy we call Captain Lightning."

"Sure," grinned Warren. "And say, speaking of comics, I came upon an old, old volume of Webster's International Dictionary in a rare-edition library in Chicago a couple of months ago, and they define 'Comic' as amusing, funny, and ludicrous; not imaginative fiction. How things change."

"Warren," said Channing soberly, "sit down!" Warren did. "Now," grinned Channing, "this screwball gadget is an idea whereby we hope to draw power out of the sun."

Warren swallowed once, and then waved for Joe. "Double," he told the restaurateur. Then to the others he said, "Thanks for seating me. I'm ill, I think. Hearing things. I could swear I heard someone say that this thing is to take power from Sol."

"Um-m-m. Remind me to quit Saturday. This is no job for a man beset by hallucinations."

"Then you'd better quit," Warren told Don. "This is no job for a bird with delusions of grandeur, either. Look, Don, you'll want this in the experimental blister at south end? On a coupler to the beam-turret so that it'll maintain direction at Sol?"

"Right. Couple it to the rotating stage if you can. Remember, that's three miles from south end."

"We've still got a few high-power selsyns," said Warren, making some notations of his own on the tablecloth. "And thanks to the guys who laid out this station some years ago, we've plenty of unused circuits from one end to the other. We'll couple it, all right. Oh, Mother. Seems to me like you got a long way off of your intended subject. Didn't you start out to make a detector for driver radiation?"

"Could be. Might even replace the coal mine. That's to be seen. Have you any idea of how long you'll be?"

"That's easy," said Don. "First, we had a jam session. Second, we've come to the conclusion that the longest way 'round is the shortest way home. We're now in the throes of building something with which to dazzle the bright-minded management of Terran Electric and thus make them susceptible to our charm. We want a free hand at the transmission tubes, and this looks like a fair bit of bait."

"I get it. Quote: 'Why buy power from Terran Electric? Hang a Channing Power Beam on your chimney pot and tap the sun?' Whoa, Mazie. Bring on the needle, Watson. Hang out the flags, fire the cannon, ring the bells; for Venus Equilateral is about to hang a pipeline right into four million tons of energy per second! Don, that's a right, smart bit of power to doodle with. Can you handle it?"

"O.K.," said Warren, sweeping the tablecloth off the table like Mysto, the Magician, right out from under the glasses. "I'll be back—wearing my asbestos pants!"

Wes Farrell looked dreamily at the ceiling. "This is a screwy joint," he said idly. "What do we do for the next ten hours?"

"Making wise moves with the transmission tubes. Glomming the barrister's desk with proposed ideas for his approval; as many as we can think of so that he'll be kept busy. We might even think of something that may work, meanwhile. Come, fellow conspirators, to horse!" Channing picked up his glass and drained it, making a wry face. "Rotten stuff—I wish I had a barrel of it!"

Channing surveyed the set-up in the blister. He inspected it carefully, as did the others. When he spoke, his voice came through the helmet receivers with a slightly tinny sound: "Anything wrong? Looks O.K. to me."

"Working in suit is not the best," said Don. "Barney, you're the bright-eyed lad, can you align the plates?"

"I think so," came the muffled booming of Barney's powerful voice. "Gimme a screwdriver!"

Barney fiddled with the plate-controls for several minutes. "She's running on dead center alignment, now," he announced.

"Question," put in Wes, "do we get power immediately, or must we wait whilst the beam gets there and returns?"

"You must run your power line before you get power," said Walt. "My money is on the wait."

"Don't crack your anode-coupling circuit till then," warned Wes. "We don't know a thing about this; I'd prefer to let it in easy-like instead of opening the gate and letting the whole four million tons per second come tearing in through this ammeter!"

"Might be a little warm having Sol in here with us," laughed Channing. "This is once in my life when we don't need a milliameter, but a million-ammeter!"

The minutes passed slowly, and then Wes announced: "She should be here. Check your anode-coupler, Barney."

Barney advanced the dial, gingerly. The air that could have grown tense was, of course, not present in the blister. But the term is just a figure of speech, and therefore it may be proper to say that the air grew tense. Fact is, it was the nerves of the men that grew tense. Higher and higher went the dial, and still the meter stayed inert against the zero-end pin.

"Not a wiggle," said Barney in disgust. He twirled the dial all the way 'round and snorted. The meter left the zero pin ever so slightly.

Channing turned the switch that increased the sensitivity of the meter until the needle stood halfway up the scale.

"Solar power, here we come," he said in a dry voice. "One-half ampere at seven volts! Three and one-half watts. Bring on your atom-smashers! Bring on your power-consuming factory districts. Hang the whole load of Central United States on the wires, for we have three and one-half watts! Just enough to run an electric clock!"

"Nope—but we'd run it. Look, fellows, when anyone tells you about this, insist that we got thirty-five hundred milliwatts on our first try. It sounds bigger."

"O.K., so we're getting from Sol just about three-tenths of the soup we need to make the set-up self sustaining," said Walt. "Wes, this in-phase anode of yours—what can we do with it?"

"If this thing worked, I was going to suggest that there is enough power out there to spare. We could possibly modulate the in-phase anode with anything we wanted, and there would be enough junk floating around in the photosphere to slam on through."

"Maybe it is that lack of selectivity that licks us now," said Don, "Run the voltage up and down a bit. There should be D. C. running around in Sol, too."

"Whatever this power-level is running at," said Barney, "we may get in-phase voltage—or in-phase power by running a line from the power terminal back. Move over, boys, I'm going to hang a test clip in here."

Barney's gloved hands fumbled a bit, but the clip was attached. He opened the anode-coupler once again, and the meter slammed against the full-scale peg.

Farrell worked with the deflection plate alignment, and then said, ruefully: "No dice, Barney had it right on the beam."

"Could it be that we're actually missing Sol?" asked Don. "I mean, could it be that line-of-sight and line-of-power aren't one and the same thing?"

"Could be," acknowledged Wes. Walt stepped to the verniers and swung the big intake tube over a minute arc. The meter jumped once more, and Channing stepped the sensitivity down again. Walt fiddled until the meter read maximum and then he left the tube that way.

"Coming up," said Channing. "We've now four times our original try. We now have enough juice to run an electric train—toy size! Someone think of something else, please. I've had my idea for the day."

Four solid, futile hours later, the power output of the solar beam was still standing at a terrifying fourteen watts. Channing was scratching furiously on a pad of paper with a large pencil; Walt was trying voltage-variations on the supply-anodes in a desultory manner; Barney was measuring the electrode spacing with a huge vernier rule, and Wes was staring at the sun, dimmed to seeable brightness by a set of dark glasses.

Wes was muttering to himself. "Electrode-voltages, O.K. ... alignment perfect ... solar power output ... not like power-line electricity ... solar composition ... Russell's mixture—"

"Thorium, C. P. metal. That's why they're shipped in metal containers in a vacuum."

"Don't work very well. In fact, if the output cathode and the input dynode are not the same metal, they won't pass power at all."

"Sounds like a brand of smoking tobacco to me. Mind making a noise like an encyclopedia and telling me what is Russell's Mixture?"

"Russell's Mixture is a conglomeration of elements which go into the making of Sol—and all the other stars," explained Don. "Hydrogen, Oxygen, Sodium, and Magnesium, Iron, Silicon, Potassium, and Calcium. They, when mixed according to the formula for Russell's Mixture, which can be found in any book on the composition of the stars, become the most probable mixture of metals. They—Russell's Mixture—go into the composition of all stars, what isn't mentioned in the mix isn't important."

"H, O, Na, Mg, Fe, Si, K, and Ca. And we, dear people, have Th, which Russell has not. Walt, call up the metallurgical lab and have 'em whip up a batch."

"Cook to a fine edge and serve with a spray of parsley? Or do we cut it into cubes—"

"Go ahead," said Channing. "Be funny. You just heard the man say that dissimilar dyno-cathodes do not work. What we need for our solar beam is a dynode of Russell's Mixture so that it will be similar to our cathode—which in this case is Sol. Follow me?"

"Yeah," said Walt, "I follow, but, brother, I'm a long way behind. But I'll catch up," he promised as he made connection between his suit-radio and the station communicator system. "Riley," he said, "here we go again. Can you whip us up a batch of Russell's Mixture?"

Riley's laugh was audible to the others, since it was broadcast by Walt's set. "Yeah, man, we can—if it's got metal in it? What, pray tell, is Russell's Mixture?"

Walt explained the relation between Russell's Mixture and the composition of Sol.

"Sounds like him. Yeah, we can make you an alloy consisting of Russell's Mixture. Tony's got it here, now, and it doesn't look hard. How big a dynode do you want?"

"But it'll be hotter than hell. Better make that six or seven hours. We may run into trouble making it jell."

Walt turned to the rest. "If any of us can sleep," he said, "I suggest it. Something tells me that tomorrow is going to be one of those days that mother told me about. I'll buy a drink."

Walt opened the anode-coupler circuit, and the needle of the output ammeter slammed across the scale and wound the needle halfway around the stop pin. The shunt, which was an external, high-dissipation job, turned red, burned the paint off of its radiator fins, and then proceeded to melt. It sputtered in flying droplets of molten metal. Smoke spewed from the case of the ammeter, dissipating in the vacuum of the blister.

"No," grinned Don. "I have a thousand-amp job that I'll sacrifice in the same happy-hearted fashion. Get an idea of the power?"

"Voltmeter was hanging up around ten thousand volts just before the amp-meter went by."

"Um-m-m. Ten thousand volts at a hundred amps. That is one million watts, my friends, and no small potatoes. To run the station's communicating equipment we need seven times that much. Can we do it?"

"We can. I'll have Warren start running the main power bus down here and we'll try it. Meanwhile, we've got a healthy cable from the generator room; we can run the non-communicating drain of the station from our plaything here. That should give us an idea. We can use a couple of million watts right there. If this gadget will handle it, we can make one that will take the whole load without groaning. I'm calling Warren right now. He can start taking the load over from the generators as we increase our intake. We'll fade, but not without a flicker."

Walt hooked the output terminals of the tube to the huge cable blocks, using sections of the same heavy cable.

"Fade her in," said Walt. He kept one eye on the line voltmeter and opened the anode-coupler slightly. The meter dipped as Warren shunted the station load over to the tube circuit. Walt brought the line voltage up to above normal, and it immediately dropped as Warren took more load from the solar intake. This jockeying went on for several minutes until Warren called: "You've got it all. Now what?"

"Start running the bus down here to take the communications load," said Don. "We're running off of an eight hundred thousand mile cathode now, and his power output is terrific. Or better, run us a high-tension line down here and we'll save silver. We can ram ten thousand volts up there for transformation. Get me?"

"Yeah," drawled Channing, "have Chuck Thomas run us a control line from the primary frequency standard. We'll control our frequency with that. O.K.?"

Channing looked at the set-up once more. It was singularly unprepossessing, this conglomeration of iron and steel and plastic. There was absolutely nothing to indicate that two and one-third million watts of power coursed from Sol, through its maze of anodes, and into the electric lines of Venus Equilateral. The cathodes and dynode glowed with their usual dull red glow, but there was no coruscating aura of power around the elements of the system. The gimbals that held the big tube slid easily, permitting the tube to rotate freely as the selsyn motor kept the tube pointing at Sol. The supply cables remained cool and operative, and to all appearances the set-up was inert.

He was interrupted by the frantic waving of Kingman, from the other side of the air lock.

"I feel slightly conscious-stricken," he said with a smile that showed that he didn't mean it at all. "But let us go and prepare the goat for shearing."

Kingman's trouble was terrific, according to him. "Mr. Channing," he complained, "you are not following our wishes. And you, Mr. Farrell, have been decidedly amiss in your hobnobbing with the engineers here. You were sent out as my consultant, not to assist them in their endeavors."

"I find that your laboratory has been changing the circuits without having previously informed me of the proposed change," complained Kingman. "I feel that I am within my rights in removing the tubes brought here. Your investigations have not been sanctioned—" He looked out through the air lock. "What are you doing out there?"

"We have just succeeded in taking power from the sun," said Don. He tried to keep his voice even, but the exultation was too high in him, and his voice sounded like sheer joy.

"Thank you," said Don. "You will no doubt be glad to hear that Wes Farrell was instrumental in this program."

"Then a certain part of the idea is rightfully the property of Terran Electric," said Kingman.

"I'm afraid not," said Don. "Dr. Farrell's assistance was not requested. Though his contribution was of great value, it was given freely. He was not solicited. Therefore, since Terran Electric was not consulted formally, Dr. Farrell's contribution to our solar power beam can not be considered as offering a hold on our discovery."

"I'm afraid so. You see, I saw what was going on and became interested, academically. I naturally offered a few minor suggestions in somewhat the same manner as a motorist will stop and offer another motorist assistance in changing a tire. The problem was interesting to me and as a problem, it did not seem to me—"

"Your actions in discussing this with members of the Venus Equilateral technical staff without authorization will cost us plenty," snapped Kingman. "However, we shall deal with you later."

"You know," said Farrell with a cheerfully malicious grin, "if you had been less stuffy about our tubes, they might be less stuffy about my contribution."

"Ah, these non-legal agreements are never satisfactory. But that is to be discussed later. What do you intend to do with your invention, Dr. Channing?"

Channing smiled in a superior manner. "As you see, the device is small. Yet it handles a couple of million watts. An even smaller unit might be made that would suffice to supply a home, or even a community. As for the other end, I see no reason why the size might not be increased to a point where it may obsolete all existing power-generating stations."

Kingman's complexion turned slightly green. He swallowed hard. "You, of course, would not attempt to put this on the market yourself."

"No?" asked Channing. "I think you'll find that Venus Equilateral is as large, if not larger, than Terran Electric, and we have an enviable reputation for delivering the goods. We could sell refrigerators to the Titan colony, if we had the V-E label on them and claimed they were indispensable. Our escutcheon is not without its adherents."

"I see," said Kingman. His present volubility would not have jogged a jury into freeing the armless wonder from a pick-pocketing charge. "Is your invention patentable?"

"I think so. While certain phases of it are like the driver tube, which, of course, is public domain, the applications are quite patentable. I must admit that certain parts are of the power transmission tube, but not enough for you to claim a hold. At any rate, I shall be busy for the next hour, transmitting the details to Washington, so that the Interplanetary Patent Office may rule on it. Our Terran legal department has a direct line there, you know, and they have been directed to maintain that contact at all costs."

"Certainly. They are public carriers. You will not be restricted any more than any other man. I am certain that our right to transmit company business without waiting for the usual turn will not be contested."

"Oh, no. Believe me. But wait, Dr. Channing. Is there no way in which we can meet on a common ground?"

"Supposing that we offer you full and unrestricted rights to any or all developments you or we make on the Martian transmission tubes?"

"Yes? You know, Kingman, I'm not too sure that Venus Equilateral wants to play around with power except as a maintenance angle. What if we toss the solar beam to the public domain? That is within our right, too."

Kingman's green color returned, this time accompanied with beads of sweat. He turned to Farrell. "Is there nothing we can do? Is this patentable?"

Kingman excused himself. He went to the office provided for him and began to send messages to the Terran Electric Company offices at Chicago. The forty-minute wait between message and answer was torture to him, but it was explained to him that light and radio crossed space at one hundred and eighty-six thousand miles per second and that even an Act of Congress could do nothing to help him hurry it. Meanwhile, Channing's description tied up the Terran Beam for almost an hour at the standard rate of twelve hundred words per minute. Their answers came within a few minutes of one another.

Channing tossed the 'gram before Kingman. "Idea definitely patentable," said the wire.

Kingman stood up. Apparently the lawyer believed that his pronouncement would carry more weight by looming over the smiling, easy-going faces of his parties-of-the-second-part. "I am prepared to negotiate with your legal department; offering them, and you, the full rights to the transmission tube. This will include full access to any and all discoveries, improvements, and/or changes made at any time from its discovery to the termination of this contract, which shall be terminated only by absolute mutual agreement between Terran Electric and Venus Equilateral.

"In return for this, Venus Equilateral will permit Terran Electric to exploit the solar beam tube fully and freely, and exclusively—"

"Make that slightly different," said Channing. "Terran Electric's rights shall prevail exclusively—except within the realm of space, upon man-made celestial objects, and upon the satellites and minor natural celestial bodies where sub-relay stations of the Interplanetary Communications Company are established."

Kingman thought that one over. "In other words, if the transport companies desire to use the solar beam, you will hold domain from the time they leave an atmosphere until they again touch—"

"Let's not complicate things," smiled Don cheerfully. "I like uncomplicated things."

Kingman smiled wryly. "I'm sure," he agreed with fine sarcasm. "But I see your point. You intend to power the communications system with the solar beam. That is natural. Also, you feel that a certain amount of revenue should be coming your way. Yes, I believe that our legal departments can agree."

"So let's not make the transport companies change masters in mid-space," smiled Don.

"You are taking a lot on your shoulders," said Kingman. "We wouldn't permit our technicians to dictate the terms of an agreement."

"You are not going to like Venus Equilateral at all," laughed Don. "We wouldn't permit our legal department to dabble in things of which they know nothing. Years ago, when the first concentric beam was invented, which we now use to punch a hole in the Heaviside Layer, communications was built about a group of engineers. We held the three inner planets together by the seat of our pants, so to speak, and nurtured communications from a slipshod, hope-to-God-it-gets-through proposition to a sure thing. Funny thing, but when people were taking their messages catch as catch can, there was no reason for legal lights. Now that we can and do insure messages against their loss, we find that we are often tied up with legal red tape.

"Otherwise, we wouldn't have a lawyer on the premises. They serve their purpose, no doubt, but in this gang, the engineers tell the attorneys how to run things. We shall continue to do so. Therefore you are speaking with the proper parties, and once the contract is prepared by you, we shall have an attorney run through the whereases, wherefores, and parties of the first, second, and third parts to see that there is no sleight of hand in the microscopic type."

"You're taking a chance," warned Kingman. "All men are not as fundamentally honest as Terran Electric."

"Kingman," smiled Channing, "I hate to remind you of this, but who got what just now? We wanted the transmission tube."

"We have a hunk of that, too. It would probably have been a mere matter of time before some bright bird at Terran found the thing as it was."

"I shall see that the contract gives you domain over man-made objects in space—including those that occasionally touch upon the natural celestial objects. Also the necessary equipment operating under the charter of Venus Equilateral, wherever or whenever it may be, including any future installations."

"You may have trouble understanding our feelings. We are essentially a space-born company, and as such we can have no one at the helm who is not equipped to handle the technical details of operations in space." Channing smiled reminiscently. "We had a so-called efficiency expert running Venus Equilateral a couple of years ago, and the fool nearly wrecked us because he didn't know that the airplant was not a mass of highly complicated, chemical reaction machinery instead of what it really is. Kingman, do you know what an airplant is?"

"You'll sit down hard when I tell you that the airplant is just what it is. Martian saw grass! Brother Burbank tossed it out because he thought it was just weeds, cluttering up the place. He was allergic to good engineering, anyway."

"That may be good enough in space," said Kingman, "but on Terra, we feel that our engineers are not equipped to dabble in the legal tangles that follow when they force us to establish precedent by inventing something that has never been covered by a previous decision."

"O.K.," said Don. "Every man to his own scope. Write up your contract, Kingman, and we'll all climb on the band wagon with our illiterary X's."

In Evanston, north of Chicago, the leaves changed from their riotous green to a somber brown, and fell to lay a blanket over the earth. Snow covered the dead leaves, and Christmas, with its holly, went into the past, followed closely by New Year's Eve with its hangover.

And on a roof by the shore of Lake Michigan, a group of men stood in overcoats beside a huge machine that towered above the great letters of the Terran Electric Company sign that could be seen all the way from Gary, Indiana.

It was a beautiful thing, this tube; a far cry from the haywire thing that had brought solar power to Venus Equilateral. It was mounted on gimbals, and the metal was bright-plated and perfectly machined. Purring motors caused the tube to rotate to follow the sun.

"Good. We can't miss with this one. There may have been something sour with the rest, but this one ran Venus Equilateral—the whole relay station—for ten days without interruption."

He faced the anxious men in overcoats. "Here we go," he said, and his hand closed upon the switch that transferred the big tube from test power to operating power.

The engineer closed the switch, and stepped over to the great, vaned, air-cooled ammeter shunt. On a panel just beyond the shunt the meter hung—

"Oh, now look," said the project engineer. "This isn't hell, where the equipment is always perfect except that it doesn't work."

"This is hell," announced his assistant. "The thing is perfect—except that it doesn't work."

"We've changed nothing, and we handled that gadget like it was made of cello-gel. We're running the same kind of voltage, checked on standard voltmeters. We're within one-tenth of one percent of the original operating conditions. But—no power."

The beams between Terra and Venus Equilateral carried furious messages for several hours. Channing's answer said: "I'm curious. Am bringing the experimental ship to Terra to investigate."

The project engineer asked: "Isn't that the job they hooked up to use the solar power for their drive?"

Channing was taking a chance, running the Relay Girl to Terra, but he knew his ship, and he was no man to be overcautious. He drove it to Terra at three G, and by dead reckoning, started down into Terra's blanket of air, heading for the Terran Electric plant which was situated on the lake shore.

Then down out of the cloudless sky came the Relay Girl in a free fall. It screamed with the whistle of tortured air as it fell, and it caught the attention of every man that was working at Terran Electric.

Only those on the roof saw the egg-shaped hull fall out of the sky unchecked; landing fifteen hundred yards offshore in Lake Michigan.

Cautiously sliding down, a minute lifeship less than the size of a freight car came to a landing in the Terran Electric construction yard. Channing emerged, his face white. He bent down and kissed the steel grille of the construction yard fervently.

Someone ran out and gave Channing a brown bottle. Don nodded, and took a draw of monstrous proportions. He gagged, made a face, and smiled in a very wan manner.

"Dunno: Was coming in at three G. About four hundred miles up, the deceleration just quit. Like that! I made it to the skeeter, here, in just about enough time to get her away with about two miles to go. Whoosh!"

Don dug into his pocket and found cigarettes. He lit up and drew deeply. "Something cockeyed, here. That stoppage might make me think that my tube failed; but—"

"You suspect that our tube isn't working for the same reason?" finished the project engineer.

"Yes. I'm thinking of the trick, ultra-high powered, concentric beams we have to use to ram a hole through the Heaviside Layer. We start out with three million watts of sheer radio frequency and end up with just enough to make our receivers worth listening to. Suppose this had some sort of Heaviside Layer?"

"In which case, Terran Electric hasn't got solar power," said the project engineer. "Tim, load this bottle into the Electric Lady, and we'll see if we can find this barrier." To Channing, he said: "You look as though you could stand a rest. Check into a hotel in Chicago and we'll call you when we're ready to try it out."

Channing agreed. A shave, a bath, and a good night's sleep did wonders for his nerves, as did a large amount of Scotch. He was at Terran Electric in the morning, once more in command of himself.

Up into the sky went the ship that carried the solar tube. It remained inert until the ship passed above three hundred and forty miles. Then the ammeter needle swung over, and the huge shunt grew warm. The tenuous atmosphere outside of the ship was unchanged, yet the beam drew power of gigantic proportions.

They spent hours rising and falling, charting this unknown barrier that stopped the unknown radiation from bringing solar power right down to earth. It was there, all right, and impervious. Above, megawatts raced through the giant shunt. Below, not even a microammeter could detect a trace of current.

"O.K., Don," said the project engineer. "We'll have to do some more work on it. It's nothing of your doing."

Mark Kingman's face was green again, but he nodded in agreement. "We seem to have a useless job here, but we'll think of something."

They studied the barrier and established its height as a constant three hundred and thirty-nine, point seven six miles above Terra's mythical sea level. It was almost a perfect sphere, that did not change with the night and day, as did the Heaviside Layer. There was no way to find out how thick it was, but thickness was of no importance, since it effectively stopped the beam.

Then as Don Channing stepped aboard the Princess of the Sky to get home again, the project engineer said: "If you don't mind, I think we'll call that one the Channing Layer!"

"Yeah," grinned Don, pleased at the thought, "and forever afterward it will stand as a cinder in the eye of Terran Electric."

Interlude:

Baffled and beaten, Mark Kingman returned to Terran Electric empty handed. He hated science and the men who revelled in it, though he was not above using science—and the men who revelled in it—to further his own unscientific existence. The poetic justice that piled blow upon blow on his unprotected head was lost on Mark Kingman and he swore eternal vengeance.

With a say in the operations at Terran Electric, Kingman directed that the engineers and scientists work furiously to discover something about this strange radiation that made the energy beam possible, that drove spacecraft across the void, and which now was drawing power out of the sun to feed the requirements of men who owed allegiance to Venus Equilateral.

Kingman was losing his sense of values. He accused Venus Equilateral of trickery. Quietly, of course, for people had faith in the operations of the relay station personnel and would stand for no criticism. Because people found Venus Equilateral and all that went with it both good and upstanding in the face of what Mark Kingman believed, it infuriated him to the point of illegality.

And the evil fate that makes evil men appear to flourish smiled upon Mark Kingman, while all that Channing had to fight back with was his faith in the unchanging physical laws of science.

But Kingman thought he was smart enough to beat Venus Equilateral at their own business!

BEAM PIRATE

Mark Kingman was in a fine state of nerves. He looked upon life and the people in it as one views the dark-brown taste of a hangover. It seemed to him at the present time that the Lord had forsaken him, for the entire and complete success of the solar beam had been left to Venus Equilateral by a sheer fluke of nature.

Neither he, nor anyone else, could have foreseen the Channing Layer, that effectively blocked any attempt to pierce it with the strange, sub-level energy spectrum over which the driver tube and the power-transmission tube worked, representing the so-called extremes of the spectrum.

But Venus Equilateral, for their part, was well set. Ships plied the spaceways, using their self-contained power only during atmospheric passage, and paid Venus Equilateral well for the privilege. The relay station itself was powered on the solar beam. There were other relay stations that belonged to the Interplanetary Communications Company; Luna, Deimos and Phobos, and the six that circled Venus in lieu of a satellite; all were powered by the solar beam. The solar observatory on Mercury used but little power, so the needs of the observatory became the sole income for Terran Electric's planetary rights of the solar beam, since Mercury owned no air of its own.

Mark Kingman was beginning to feel the brunt of Channing's statement to the effect that legal-minded men were of little importance when it came to the technical life in space, where men's lives and livelihood depended more on technical skill than upon the legal pattern set for their protection in the complex society of planetary civilization.

So, like the man who doggedly makes the same mistake twice in a row, Kingman was going to move Heaven, Hell, and three planets in an effort to take a swing at the same jaw that had caught his fist between its teeth before.

Out through the window of his office, he saw men toiling with the big tube on the far roof; the self-same tube that had carried the terrific load of Venus Equilateral for ten days without interruption and with no apparent overload. Here on Terra, its output meter, operating through a dummy load, showed not the slightest inclination to leave the bottom peg and seek a home among the higher brackets.

So Kingman cursed and hated himself for having backed himself into trouble. But Kingman was not a complete fool. He was a brilliant attorney, and his record had placed him in the position of Chief Attorney for Terran Electric, which was a place of no mean importance. He had been licked on the other fellow's ground, with the other fellow's tools.

He picked up papers that carried, side by side, the relative assets of Venus Equilateral and Terran Electric. He studied them and thought deeply.

To his scrutiny, the figures seemed about equal, though perhaps Venus Equilateral was a bit ahead.

But—he had been licked on the other fellow's ground with the other fellow's weapons. He thought that if he fought on his own ground with his own tools he might be able to swing the deal.

Terran Electric was not without a modicum of experience in the tools of the other fellow. Terran Electric's engineering department was brilliant and efficient, too; at least the equal of Channing and Franks and their gang of laughing gadgeteers. That not only gave him the edge of having his own tools and his own ground, but a bit of the other fellow's instruments, too. Certainly his engineering department should be able to think of something good.

William Cartwright, business manager for Venus Equilateral, interrupted Don and Walt in a discussion. He carried a page of stock market quotations and a few hundred feet of ticker tape.

Channing put down his pencil and leaned back in his chair. Walt did likewise, and said: "What's brewing?"

"The stock has been cutting didoes. We've been up and down so much it looks like a scenic railway."

"Even, mostly; but from my experience, I would say that some bird is playing hooky with Venus Equilateral, Preferred. The common is even worse."

"Not too good. It is more than possible that some guy with money and the desire might be able to hook a large slice of V.E. Preferred. I don't think they could get control, but they could garner a plurality from stock outstanding on the planets. Most of the preferred stock is in the possession of the folks out here, you know, but aside from yourself, Walt, and a couple dozen of the executive personnel, the stock is spread pretty thin. The common stock has a lot of itself running around loose outside. Look!"

Cartwright began to run off the many yards of ticker tape. "Here, some guy dumped a boatload at Canalopsis, and some other guy glommed onto a large hunk at New York. The Northern Landing Exchange showed a bit of irregularity during the couple of hours of tinkering, and the irregularity was increased because some bright guy took advantage of it and sold short." He reeled off a few yards and then said: "Next, we have the opposite tale. Stuff was dumped at Northern Landing, and there was a wild flurry of bulling at Canalopsis. The Terran Exchange was just flopping up and down in a general upheaval, with the boys selling at the top and buying at the bottom. That makes money, you know, and if you can make the market tick your way—I mean control enough stuff—your purchases at the bottom send the market up a few points, and then you dump it and it drops again. It wouldn't take more than a point or two to make a guy rich, if you had enough stock and could continue to make the market vacillate."

"That's so," agreed Don. "Look, Bill, why don't we get some of our Terran agents to tinkering, too? Get one of our best men to try to outguess the market. As long as it is being done systematically, he should be able to follow the other guy's thinking. That's the best we can do unless we go Gestapo and start listening in on all the stuff that goes through the station here."

"Yeah, but we'd all land in the hoosegow for breaking the secrecy legislation. You know. 'No one shall ... intercept ... transmit ... eavesdrop upon ... any message not intended for the listener, and ... shall not ... be party to the use of any information gained ... et cetera.' That's us. The trouble is this lag between the worlds. They can prearrange their bulling and bearing ahead of time and play smart. With a little luck, they can get the three markets working just so—going up at Northern Landing; down at Terra; and up again at Canalopsis, just like waves in a rope. By playing fast and loose on paper, they can really run things hell, west and crooked. Illegal, probably, since they each no doubt will claim to have all the stock in their possession, and yet will be able to sell and buy the same stock at the same time in three places."

"Not at all, if you figure things just right. At a given instant, Pete may be buying at sixty-five on Venus; Joe might be selling like furious at seventy-one on Mars; and Jimmy may be bucking him up again by buying at sixty-five on Terra. Then the picture and the tickers catch up with one another, and Joe will start buying again at sixty-five, whilst Pete and Jimmy are selling at seventy-one. Once they get their periodicity running, they're able to tinker the market for quite a time. That's where your man comes in, Bill. Have him study the market and step in at the right time and grab us all a few cheap ones. Get me?"

"Sure," said Cartwright. "I get it. In that way, we'll tend to stabilize the market, as well as getting the other guy's shares."

"Right. I'll leave it up to you. Handle this thing for the best interests of all of us."

Cartwright smiled once again, and left with a thoughtful expression on his face. Channing picked up the miniature of the power-transmission tube and studied it as though the interruption had not occurred. "We'll have to use about four of these per stage," he said. "We'll have to use an input terminal tube to accept the stuff from the previous stage, drop it across the low-resistance load, resistance couple the stage to another output terminal tube where we can make use of the coupling circuits without feedback. From there into the next tube, with the high resistance load, and out of the power-putter-outer tube across the desk to the next four-bottle stage."

"That's getting complicated," said Walt. "Four tubes per stage of amplification."

"Sure. As the arts and sciences get more advanced, things tend to get more complicated."

"That's essentially correct," agreed Walt with a smile. "But you're foreguessing. We haven't even got a detector that will detect driver radiation."

"I know, and perhaps this thing will not work. But after all, we've got the tubes and we might just as well try them out just in case. We'll detect driver radiation soon enough and then we might as well have a few odd thoughts on how to amplify it for public use. Nothing could tickle me more than to increase those three circles on our letterhead to four. 'Planet to Planet, and Ship to Ship' is our hope. This one-way business is not to my liking. How much easier it would have been if I'd been able to squirt a call in to the station when I was floating out there beyond Jupiter in that wrecked ship. That gave me to think, Walt. Driver radiation detection is the answer."

"We'll use the detector to direct our radio beam, and the ship can have a similar gadget coupled to their beam, detecting a pair of drivers set at one hundred and eighty degrees from one another so the thrust won't upset the station's celestial alignment. We can point one of them at the ship's course, even, making it easier for them."

"Speaking of direction," said Walt thoughtfully, "have you figured why the solar beam is always pointing behind Sol?"

"I haven't given that much thought. I've always thought that it was due to the alignment plates not being in linear perfection so that the power beam bends. They can make the thing turn a perfect right angle, you know."

"Well, I've been toying with the resurrected heap you dropped into Lake Michigan a couple of months ago, and I've got a good one for you. You know how the beam seems to lock into place when we've got it turned to Sol, not enough to make it certain, but more than detectably directive?"

"Yep. We could toss out the motor control that keeps her face turned to the sun."

"That's what I was hoping to gain—" started Walt, but he stopped as the door opened and Arden entered, followed by a man and woman.

"This is Jim Baler and his sister Christine," said Arden. "Baler, the guy with the worried look on his face is my legally wedded souse—no, spouse. And the guy with the boudoir gorilla gleam in his vulpine eyes is that old vulture, Walt Franks."

Walt took the introduction in his stride and offered Christine his chair. Arden stuck her tongue out at him, but Walt shrugged it off. Channing shook hands with Jim Baler and then sought the "S" drawer of his file cabinet. He found the Scotch and the soda, and then grinned: "Should have the ice under 'I' but it's sort of perishable, and so we keep it in the refrigerator. Arden, breach the 'G' drawer, please, and haul out the glasses. I suppose we could refrigerate the whole cabinet, but it wouldn't sound right if people heard that we kept their mail on ice. Well—"

"Here's how, if we don't already know," said Walt, clinking glasses with Christine.

"Walt earned that 'wolf' title honestly," laughed Arden, "he likes to think. Frankly, he's a sheep in wolf's clothing!"

"He invents. He scribbles a bit. He cuts doodles on tablecloths, and he manages to get in the way all the time," said Don. "We keep him around the place for his entertainment value."

"Quiet, Walter, or I shall explain the sordid details of the Walter Franks Electron Gun."

"And that'll take care of that," said Arden. "But I think we interrupted something. What were you saying about gaining, Walt?"

"Oh, I was saying that I was tinkering around with the Anopheles. We hooked it up with the solar beam for power, and I got to wondering about that discrepancy. The faster you go, the greater is the angular displacement, and then with some measurements, I came up with a bugger factor—"

"You'll learn," said Arden, "that the boys out here have a language all their own. I've heard them use that one before. The bugger factor is a sort of multiplying, or dividing, or additive, or subtractive quantity. You perform the mathematical operation with the bugger factor, and your original wrong answer turns into the right answer."

"Oh, sure," answered Arden. "People don't realize it, but that string of 4's in the derivation of Bode's law is a bugger factor."

"You," said Christine to Walt, "will also tell me what Bode's law is—but later."

"O.K.," grinned Walt. "At any rate, I came up with a bugger factor that gave me to think. The darned solar beam points to where Sol actually is!"

"Whoosh!" exclaimed Channing. "You don't suppose we're tinkering with the medium that propagates the law of gravity?"

"I don't know. I wouldn't know. Has anyone ever tried to measure the velocity of propagation of the attraction of gravity?"

Jim Baler smiled. "No wonder Barney was a little wacky when he got home. I come out here to take a look around and maybe give a lift to your gang on the transmission tube—and bump right into a discussion on the possibility of modulating the law of gravity!"

"Now he gets technical about it. You started out a couple of months ago to detect driver radiation, and ended up by inventing a beam that draws power out of the sun. Think you'll ever find the driver radiation?"

"Yeah," drawled Arden. "And I'll bet a hat that when they do, they won't have any use for it. I've seen 'em work before."

"Incidentally," said Christine, "you mentioned the Anopheles, and I think that is the first ship I've ever heard of that hasn't a feminine name. How come?"

"The mosquito that does the damage is the female," grinned Jim. "The Mojave spaceyards owns a sort of tender craft. It has a couple of big cranes on the top and a whole assortment of girders near the bottom. It looks like, and is also called The Praying Mantis. Those are also female: at least the ones that aren't afraid of their own shadow are."

Channing said suddenly: "Walt, have you tried the propagation-time of the solar beam on the Anopheles?"

"By leaving the controls set for one G, and then starting the ship by swapping the tube energizing voltages from test power to operating power."

"Sure. As we know, the amount of energy radiated from the sun upon a spot the size of our solar tube is a matter of peanuts compared to the stuff we must get out of it. Ergo, our beam must go to Sol and collect the power and draw it back down the beam. Measure the transit-time, and we'll know."

"That's an idea. I've got a micro-clock in the lab. We can measure it to a hundred-millionth of a second. Anyone like to get shook up?"

"Snapping from zero to one G all to oncet-like isn't too gentle. She'll knock your eyes out."

Channing groaned in mock anguish. "Here goes another closet full of female haberdashery. I'm going to close that corridor some day, or put a ceiling on the quantity of sales, or make it illegal to sell a woman anything unless she can prove that 'she has nothing to wear!'"

"You would," snorted Arden. "Come on, Chris. Better than the best of three worlds is available."

"That sort of leaves me all alone," said Don. "I'm going to look up Wes Farrell and see if he's been able to make anything worth looking at for a driver detector."

Don found Wes in the laboratory, poring over a complicated circuit. Farrell was muttering under his breath, and probing deep into the maze of haywire on the bench.

"Not right now," objected Wes. "I haven't got that hollow leg that your gang seem to have developed. Besides, I'm on the trail of something."

"I got a wiggle out of the meter there a few minutes ago. I'm trying to get another one."

"Wavered up and down like fierce for about a minute after I turned it on. Then it died quick, and has been dead ever since."

"Nope. I've checked every part in this circuit, and everything is as good as it ever will be. No, something external caused that response."

"You've tried the solar tube with a dynode of the same alloy as the driver cathodes?"

"Uh-huh. Nothing at all. Oh, I'll take that back. I got a scratch. With a pre-meter gain of about four hundred decibels, I read three micro-microamperes. That was detected from a driver tube forty feet across the room, running at full blast. I wondered for a minute whether the opposing driver was doing any cancellation, and so I took a chance and killed it for about a half second, but that wasn't it."

"As best as I could measure, it was something to the tune of inversely proportional to the cube of the distance. That's not normal for beams since it shows that the stuff isn't globularly radiated. But the amplifier gain was hanging right on the limit of possible amplification, and the meter was as sensitive as a meter can be made, I think. You couldn't talk from one end of Venus Equilateral to the other with a set like that."

"Oh, I got foolish and tried a tuned circuit across the output of one of the miniature transmission tubes. It's far enough away from the big beams and stuff at the north end so that none of the leakage can cause trouble. Besides, I'm not getting anything like our beam transmissions."

Channing laughed. "Uh-huh, looks to me like you're not getting much of anything at all."

Farrell smiled wryly. "Yeah, that's so," he agreed. "But look, Don, Hertz himself didn't collect a transcontinental short-wave broadcast on his first attempt."

"If Hertz had been forced to rely upon vacuum tubes, his theories couldn't have been formulated, I think," said Channing. "At least, not by him. The easier frequencies and wave lengths are too long; a five hundred meter dipole can't be set up in a small room for laboratory tinkering. The kind of frequencies that come of dipoles a couple of feet long, such as Hertz used, are pretty hard to work with unless you have special tubes."

"Hertz had rotten detectors, too. But he made his experiments with spark-gap generators, which gave sufficient high-peak transients to induce spark-magnitude voltages in his receiving dipole."

"I'm not too sure of that tuned-circuit idea of yours, Wes. Go ahead and tinker to your heart's content, but remember that I'm skeptical of the standard resonance idea."

"Because we've been tinkering with driver tubes for years and years—and we have also been gadgeting up detectors, radio hootnannies, and stuff of the electronic spectrum all the way from direct current to hard X-rays, and we have yet to have anything react to driver radiation. Ergo, I'm skeptical."

"Don," he said with a laugh in his voice, though it was apparent that he felt slightly guilty about laughing, "got a 'gram from Addison, the project engineer on the solar beam from Terran Electric. Says: 'Finally got through Channing Layer. Power by the megawatt hour in great shape. But the atmosphere from the Channing Layer right down to the snout of the tube is a dull red scintillation. Like the driver tube trail—it ionizes the atmosphere into ozone. Power by the megawatt, and ozone by the megaton.'"

"Plenty, according to the rest of this. It looks to me like a sort of 'denatured' power system. There it is, all nice and potent, cheap, and unlicensed. But the second swallow going down meets the first one on the way back. Power they got—but the ozone they can't take; it's poisonous like a nice dose of chlorine. Poor Terran Electric!"

Mark Kingman sat in the control room of a ship of space and worried. Below the dome, Venus covered three-quarters of the sky, and it circled slowly as the Terran Electric ship oscillated gently up and down.

Before Kingman, on the desk, were pages of stock market reports. On a blackboard, a jagged line denoted the vacillation of Venus Equilateral Preferred. This phase of his plan was working to perfection. Gradually, he was buying share after share out of uninterested hands by his depredations. Soon he would have enough stock to stage a grand show, and then he could swing the thing his way.

He gloated over that. His belief that he could beat this Venus Equilateral crowd if he fought them on his ground with his weapon was being corroborated. That, plus the fact that he was using some of Venus Equilateral's own thunder to do the job, was giving him to think that it was but a matter of time.

And the poor fools were not aware of their peril. Oh, some bird was trying to buck him, but he was not prepared as Kingman was, nor had he the source of information that Kingman had.

And there it came again! A wild, cacophonous wailing, like a whole orchestra of instruments playing at random, in random keys. It shook the very roots of the body, that terrible caterwauling, and not only did it shake the body, and the mind, but it actually caused loose plates to rattle in the bulkhead, and the cabinet doors followed in unison. The diapason stop was out for noon, and the racket filled the small control room and bounced back and forth, dinning at the ears of Kingman as it went by. It penetrated to the upper reaches of the ship, and the crew gritted their teeth and cursed the necessity of being able to hear orders, for cotton plugs would have been a godsend and a curse simultaneously. Anything that would blot that racket out would also deafen them to the vital orders necessary to the operation of the ship in this precarious poising maneuver.

Two hundred sheer watts of undistorted audio power boomed forth in that tiny room—two hundred watts of pure, undistorted power to racket forth something that probably started out as sheer distortion—

Faintly striving against that fearful racket there came a piping, flat-sounding human voice that said: "Kingman! V.E. Preferred just hit eighty-nine!"

Kingman scowled and punched on the intership teletype machine. Using the communicator set with that racket would have been impossible.

The radio man read the note that appeared on his 'type, and smiled grimly. He saw to his helio-mirror and sighted through a fine telescope at a spot on Venus, three thousand miles below. The helio began to send its flashing signal to this isolated spot near the Boiling River, and it was read, acknowledged, and repeated for safety's sake. The radio man flashed "O.K." and went back to his forty-seventh game of chess with the assistant pilot.

The helio man on the Boiling River read the message, grinned, and stepped to the telephone. He called a number at Northern Landing, and a tight beam sped across the northern quarter of Venus to a man connected with the Venus Stock Market. The man nodded, and said to another: "Buy fifteen hundred—use the name of Ralph Gantry this time."

The stock purchased under the name of Ralph Gantry was signed, sealed and delivered exactly fifteen minutes before the ticker projection on the grand wall of the Exchange showed the V.E. Preferred stock turn the bottom curve and start upward by hitting eighty-nine!

Back in the Terran Electric spaceship Kingman's ears were still beset by the roaring, alien music.

He was sitting in his chair with his head between his hands, and did not see the man approaching the instrument panel with a pair of side-cutters in one hand. The man reached the panel, lifted it slightly, and reached forward. Then Kingman, hearing a slight imperfection in the wail of the speaker, looked up, jumped from his chair, and tackled the engineer.

The music stopped at his third word, and the scream of his voice in the silence of the room almost scared Kingman himself.

"I can't. I'm not brilliant enough to devise a circuit that will cut that noise and still permit the entry of your fellow on Luna."

"Ben, as far as I know, that relay is what Channing and his gang would give their whole station for—and will, soon enough. I don't care how it works—or why!"

"Yeah, but we've got the only detector for driver radiation in this part of the universe! I'm not going to have it wrecked by a screwball engineer who doesn't give a care what's going on as long as he can tinker with something new and different. What do we know about it? Nothing. Therefore how can you learn anything about it? What would you look for? What would you expect to find?"

"I don't know. As best as we can calculate, driver radiation propagates at the square of the speed of light, and that gives us a twenty-four minute edge on Venus Equilateral at the present time. For all I know, that music may be coming from the other end of the galaxy. At the square of the speed of light, you could talk to Centauri and get an answer in not too long."

"But if we had a chance to tinker with that relay, we might be able to find out what tunes it and then we can tune in the Lunar station and tune out that cat-melody."

"I'm running this show—and this relay is going to stay right where it is. I don't care a hoot about the control circuit it breaks; these controls are set, somehow, so that we can detect driver radiations and I'm not taking any chances of having it ruined."

The speaker spoke in that faint, flat-toned human voice again. It was easy to see that all that gain was necessary to back up the obviously faint response of Kingman's detector. The speaker said: "Kingman! Addison got power through the Channing Layer!"

That was all for about an hour. Meanwhile, the mewling tones burst forth again and again, assaulting the ears with intent to do damage. The messages were terse and for the most part uninteresting. They gave the market reports: they intercepted the beam transmissions through the Terran Heaviside Layer before they got through the Lunar Relay Station, inspected the swiftly-moving tape and transmitted the juicy morsels to Kingman via the big driver tube that stood poised outside of the landed spaceship.

Kingman enjoyed an hour of celebration at Addison's success, and then the joy turned to bitter hate as the message came through telling of the ozone that resulted in the passage of the solar beam through the atmosphere. The success of the beam, and the utter impossibility of using it were far worse than the original fact of the beam's failure to pass the Channing Layer.

So Kingman went back to his stock market machinations and applied himself diligently. And as the days wore on, Kingman's group manipulated their watered stock and ran the price up and down at will, and after each cycle Kingman's outfit owned just one more bit of Venus Equilateral.

Terran Electric would emerge from this battle with Venus Equilateral as a subsidiary—with Kingman at the helm!

Walt Franks entered Channing's office with a wild-eyed look on his face. "Don! C²!"

"It has energy, energy has mass, mass cannot travel faster than the limiting speed of light."

"O.K. It can't do it. But unless my measurements are all haywire, the beam gets to Sol and back at C². I can prove it."

"Yeah? How? You couldn't possibly measure an interval so small as two times sixty-seven million miles—the radius of Venus' orbit—traversed at the speed of light, squared."

"Got power out of Sirius. And unless I've forgotten how to use a micro-clock, it figured out from here to Sirius and back with the bacon in just about ninety-three percent of the speed of light squared. Seven percent is well within the experimental error, I think, since we think of Sirius as being eight and one-half light years away. That's probably not too accurate as a matter of fact, but it's the figure I used. But here we are. Power from Sirius at C². Thirty-five billion miles per second! This stuff doesn't care how many laws it breaks!"

"Hm-m-m. C², hey? Oh, lovely. Look, Walt, let's run up and take a whirl at Wes Farrell's detector. I'm beginning to envision person-to-person, ship-to-ship service, and possibly the first Interplanet Network. Imagine hearing a play-by-play account of the Solar Series!"

"Wes has something. First glimmer we've had. I think this is the time to rush into it with all eight feet and start pushing!"

"Same gang as usual. Chuck and Freddie Thomas, Warren, Wes Farrell, of course, and you can get Jim Baler into it, too. No, Walt, Christine Baler is not the kind of people you haul into a screwdriver meeting."

"I know. But you're needed, and if she were around, you'd be a total loss as far as cerebration."

"Um! But he isn't here. O.K., no Christine in our conference. I'll have Jeanne call the screwballs on the communicator."

"We have a detector. It is about as efficient as a slab of marble; only more so. We can get a tinkle of about ten micromicroamps at twenty feet distance from a driver tube using eight KVA input, which if we rate this in the usual spaceship efficiency, comes to about one-half G. That's about standard, for driver tubes, since they run four to a ship at two G total.

"Now, that is peanuts. We should be able to wind a megammeter around the peg at twenty feet. Why, the red ionization comes out of the tube and hits our so-called detector, and the amount of ozone it creates is terrific. Yet we can't get a good reading out of it."

"A four-turn coil on a ceramic form, in series with a twenty micromicrofarad tuning condenser. I've been using a circular plate as a collector."

"Nope. Funny thing, though, it won't work without a condenser in the circuit. I can use anything at all there without tuning it. But, darn it, the coil is the only one that works."

"Inductance, distributed capacity, and factor 'Q' are all right on the button with two more I made. Nothing dioding."

"Nothing in my mind. I've tried about three hundred similar coils, and not a wiggle since. That's the only one."

Chuck Thomas said: "Wes, have you tried your tube-amplifier system ahead of it?"

"Yes, and nothing at all happens then. I don't understand that one, because we know that any kind of input power will be re-beamed as similar power. I should think that the thing will amplify the same kind of stuff. I've used a solar beam miniature with a driver-alloy dynode in it, but that doesn't work either."

Don stood up and picked up the coil. "Fellows, I'm going to make a grand, old college try."

"I've got a grand idea, here. One, I'm still remembering that business of making the receptor dynode of the same alloy as the transmitter cathode. I've a hunch that this thing is not so much an inductor, but something sour in the way of alloy-selectivity. If I'm right, I may cut this in half, and make two detectors, each of similar characteristics. Shall I?"

"Go ahead. We've established the fact that it is not the physico-electrical characteristics of that coil," said Wes. "I, too, took my chances and rewound that same wire on a couple of other forms. So it doesn't count as far as inductance goes. So we can't ruin anything but the total make-up of the wire. I think we may be able to re-establish the wire by self-welding if your idea doesn't work. Now, unless we want to search the three planets for another hunk of wire to work like this one did, without knowing what to look for and therefore trying every foot of wire on three planets—"

"I'll cut it," said Channing with a smile. His cutters snipped, and then fastened one end of the wire to the coil, stripping the other portion off and handing it to Chuck Thomas, who rewound it on another form.

The beam tubes were fired up, and the smell of ozone began to make itself prominent. Channing cranked up the air-vent capacity to remove the ozone more swiftly. The men applied themselves to the detector circuits, and Wes, who recognized the results, said: "This hunk works. About as good as the whole coil."

Channing replaced the first coil with the second. Wes inspected the results and said: "Not quite as good, but it does work."

"That's a thought. Our solar beam uses an incandescent dynode." Channing removed the second coil and handed it to Freddie. "Take this thing down to the metallurgical lab and tell 'em to analyze it right down to the trace of sodium that seems to be in everything. I want quantitative figures on every element in it. Also, cut off a hunk and see if the crystallographic expert can detect anything peculiar, that would make this hunk of copper wire different from any other hunk. Follow?"

"Yup," said Freddie. "We'll also start making similar alloys with a few percent variation on the composition metals. Right?"

"That's the ticket. Wes, can we evacuate a tube with this wire in it and make it incandescent?"

"Thanks. I get the program, all right. Why not have Chuck build us a modulator for the driver tube? Then when we get this thing perfected, we'll have some way to test it."

"I think so. It's easy. We'll just modulate the cathode current of the electron guns that bombard the big cathode. That is the way we adjust for drive; it should work as a means of amplitude-modulation."

"O.K.," said Channing. "We're on the rails for this one. We'll get together as soon as our various laboratories have their answers and have something further to work with."

Above Venus, Mark Kingman was listening to the wailing roar of alien symphony and cursing because he could hardly hear the voice of his Lunar accomplice saying: "V. E. Preferred just hit one hundred and two!"

Fifteen minutes before the peak hit Northern Landing, share after share was being dumped, and in addition, a message was on its way back to Terra. It went on the regular beam transmission through Venus Equilateral, carefully coded. It said:

In the ten hours that followed, Venus Equilateral stock went down and down, passed through a deep valley, and started up again. Kingman's crowd was offering twice the market for the preferred stock, and there was little to have. It took a short-time dip at three hundred, and the few minutes of decline smoked a lot of stock out of the hands of people who looked upon this chance as the right time to make their money and get out.

Then the stock began to climb again, and those people who thought that the price had been at its peak and passed were angrily trying to buy in again. That accelerated the climb, but Kingman's crowd, operating on Venus and on Mars and on Terra, were buying only, and selling not one share of Venus Equilateral.

Terran Electric stock took a gradual slide, for Kingman's crowd needed additional money. But the slide was slow, and controlled, and manipulated only for the purpose of selling short. Terran Electric stock eventually remained in the hands of Kingman's crowd, though its value was lessened.

Venus Equilateral Preferred hit four hundred and sixty-eight, and hovered. It vacillated around that point for another hour, and the market closed at four hundred and sixty-nine and three-eighths.

Kingman looked at his watch and smiled. He reached forth and cut the dinning sound of the cacophony with a vicious twist of the gain knob. Silence reigned in the spaceship; grand, peaceful silence. Kingman, his nerves frayed by the mental activity and the brain-addling music-from-nowhere, took a hot shower and went to bed.

He locked the panel of the control room first, however. He wanted no engineer tinkering with his pet relay.

Cartwright came into Channing's living room with a long face. "It's bad," he said. "Bad."

"They started to buy like mad, and I held out. Then the thing dropped a few points, and I tried to make a bit of profit, so that we could go on bolstering the market. They grabbed off my stock, and then, just like that! the market was on the way up again and I couldn't find more than a few odd shares to buy back."

"Don't worry," said Channing, "I don't think anyone is big enough to really damage us. Someone is playing fast and loose, making a killing. When this is over, we'll still be in business."

"I'm afraid so. One more flurry like today, and they'll be able to tow Venus Equilateral out and make Mars Equilateral out of it, and we won't be able to say a word."

"Not until the last drop. I'm not bragging when I say that I'm as good an operator as the next. My trouble today was not being a mind reader. I'd been doing all right, so far. I've been letting them ride it up and down with little opposition, and taking off a few here and there as I rode along. Guessing their purpose, I could count on their next move. But this banging the market sky-high has me stumped, or had me stumped for just long enough for me to throw our shirt into the ring. They took that quick—our shirt, I mean."

"There are a lot of unstable stocks that a guy could really play hob with; therefore their only reason to pick on us is to gain control!"

"Well," said Channing in a resigned voice, "about all we can do is do our best and hope we are smart enough to outguess 'em. That's your job, Cartwright. A long time ago Venus Equilateral made their decision concerning the executive branch of this company, and they elected to run the joint with technical men. The business aspects and all are under the control of men who know what they are fighting. We hire business men, just like business men hire engineers, and for the opposite purpose. You're the best we could get, you know that. If those guys get Venus Equilateral, they'll get you, too. But if you do your best and fail, we can't shoot you in the back for it. We'll all go down together. So keep pitching, and remember that we're behind you all the way!"

"Sure, if it's needed. I'd prefer Interplanetary Transport. Keg Johnson will do business with us. We've been in the way of helping them out a couple of million dollar losses; they might be anxious to reciprocate."

"O.K. I have your power of attorney, anyway. If I get in a real crack, I'll scream for I. T. to help. Right?"

Cartwright left, and as he closed the door, Channing's face took on a deep, long look. He was worried. He put his head between his hands and thought himself into a tight circle from which he could not escape. He did not hear Walt Franks enter behind Arden and Christine.

Channing looked up. "Spill," he said with a glum smile. "I could use some glad tidings right now."

"The lab just reported that that hunk of copper wire was impure. Got a couple of traces of other metals in it. They've been concocting other samples with more and less of the impurities, and Wes has been trying them as they were ready. We've got the detector working to the point where Freddie has taken the Relay Girl out for a run around the station at about five hundred miles and Wes is still getting responses!"

"Chuck rigged the Relay Girl's drivers with a voice modulator, and Freddie is jerking his head off because the acceleration is directly proportional to the amplitude of his voice, saying: 'One, two, three, four, test.' Don, have you ever figured out why an engineer can't count above four?"

"Peanuts," grinned Franks. "This stuff is not like the good old radio; the power for driving the spaceship is derived mostly, from the total disintegration of the cathode and the voltage applied to the various electrodes is merely for the purpose of setting up the proper field conditions. They draw quite a bit of current, but nothing like that which would be required to lift a spaceship at two G for a hundred hours flat."

Don smiled in a thoughtful fashion. "It doesn't look so good right now. Some gang of stock market cutthroats have been playing football with Venus Equilateral, and Cartwright says he is sure they want control. It's bad; he's been clipped a couple of hard licks, but we're still pitching. The thing I'm wondering right now is this: Shall we toss this possibility of person-to-person and ship-to-ship communication just at the right turn of the market to bollix up their machinations, or shall we keep it to ourselves and start up another company with this as our basis?"

"Sure. If we drop this idea just at the time they're trying to run the stock down, it'll cross over and take a run up, which will set 'em on their ear."

"I don't know. Better keep it to ourselves for a bit. Something may turn up. But come on down to Wes' lab and give a look at our new set-up."

Farrell was working furiously on the detector device, and as they entered, he indicated the meter that was jumping up and down. Out of a speaker there was coming the full, rich tones of Freddie Thomas' voice, announcing solemnly: "One, two, three, four, test."

Wes said, "I'm getting better, Chuck has been bettering his modulator now, and the detector is three notches closer to whatever this level of energy uses for resonance. Evacuation and the subsequent incandescence was the answer. Another thing I've found is this—" Farrell held up a flat disk about six inches in diameter with one sawcut from edge to center. "As you see, the color of this disk changes from this end of the cut, varying all the way around the disk to the other side of the cut. The darned disk is a varying alloy—I've discovered how to tune the driver-radiation through a limited range. We hit resonance of the Relay Girl's driver system just off the end of this disk. But watch while I turn the one in the set."

Farrell took a large knob and turned it, Freddie's voice faded, and became toneless. Farrell returned the knob to its original position and the reception cleared again. "Inside of that tube there," said Farrell, "I have a selsyn turning the disk, and a small induction loop that heats the whole disk to incandescence. A brush makes contact with the edge of the disk and the axle makes the center connection. Apparently this stuff passes on a direct line right through the metal, for it works."

"Why not? I can still think that the relay tube will amplify if we hook up the input and output loads correctly."

"I've got a tube already hooked up," said Walt. "It's mounted in a panel with the proper voltage supplies and so on. If your resistance calculation is correct, we should get about three thousand times amplification out of it."

He left, and returned in a few minutes with the tube. They busied themselves with the connections, and then Don applied the power.

"Run a line from the output back through a voltage-dividing circuit to the in-phase anode," suggested Walt.

"Put a potentiometer in it so we can vary the amount of voltage. After all, Barney Carroll said that the application of voltage in phase with the transmitted power is necessary to the operation of the relay tube. In transmission of D. C., it is necessary to jack up the in-phase anode with a bit of D. C. That's in-phase with a vengeance!"

"What you're thinking is that whatever this sub-level energy is, some of it should be applied to the in-phase anode?"

The cabinet provided a standard potentiometer, and as Don advanced the amount of fed-back voltage, Freddie's voice came booming in louder and louder. It overloaded the audio amplifier, and they turned the gain down as Channing increased the in-phase voltage more and more. It passed through a peak, and then Don left the potentiometer set for maximum.

"Wes," he said, "call Freddie and tell him to take off for Terra, at about four G. Have the gang upstairs hang a ship beam on him so we can follow him with suggestions. Too bad we can't get there immediately."

"What I'm worrying about is the available gain," said Wes. "That thing may have given us a gain of a couple of thousand, but that isn't going to be enough. Not for planet-to-planet service."

"Later on we may be able to hang a couple of those things in cascade," suggested Walt.

"Or if not, I know a trick that will work—one that will enable us to get a gain of several million."

"Yeah? Mirrors, or adding machines? You can't make an audio amplifier of a three million gain."

"I know it—at least not a practical one. But, we can probably use our audio modulator to modulate a radio frequency, and then modulate the driver with the RF. Then we hang a receiver onto the detector gadget here, and collect RF, modulated, just like a standard radio transmission, and amplify it at RF, convert it to IF, and detect it to AF. Catch?"

"Sure. And that gives me another thought. It might just be possible, if your idea is possible, that we can insert several frequencies of RF into the tube and hang a number of receivers on the detector, here."

Arden laughed. "From crystal detection to multiplex transmission in ten easy lessons!"

"Call Chuck and have him begin to concoct an RF stage for tube-modulation," said Don. "It'll have to be fairly low—not higher than a couple of megacycles so that he can handle it with the stuff he has available, but as long as we can hear his dulcet voice chirping that 'one, two, three, four, test,' of his, we can also have ship-to-station two-way. We squirt out on the ship beam, and he talks back on the driver transmitter."

"That'll be a help," observed Wes. "I'd been thinking by habit that we had no way to get word back from the Relay Girl."

"Meanwhile, I'm going to get this alloy-selectivity investigated right down to the last nub," said Don. "Chuck's gang can take it from all angles and record their findings. We'll ultimately be able to devise a system of mathematics for it from their analysis. You won't mind being bothered every fifteen minutes for the first week, will you, Wes? They'll be running to you in your sleep with questions until they catch up with your present level of ability in this job. Eventually they'll pass you up, and then you'll have to study their results in order to keep up."

"It's about time," smiled Arden. "I wouldn't haul you away from your first love excepting that I know you haven't eaten in eight or nine hours. I've got roast knolla."

"S'long, fellows," grinned Channing. "I'm one of the few guys in the inner system who can forget that the knolla is the North Venus brother to a pussy cat."

"I could feed you pussy cat and you'd eat it if I called it knolla," said Arden. "But you wouldn't eat knolla if I called it pussy cat."

"I mean by visual inspection. Unfortunately, there can be no comparison drawn. The Venusians will eat pussy cat, but they look upon the knolla as a household pet, not fit for Venusian consumption. So unless we revive one of the ancient Martians, who may have the intestinal fortitude—better known as guts—to eat both and describe the difference, we may never know," offered Walt.

"All the more for me," said Don. "Now, when I was in college, we cooked the dean's cat and offered it to some pledges under the name of knolla. They said—"

"We'll have macaroni for dinner," said Arden firmly. "I'll never be able to look a fried knolla in the pan again without wondering whether it caterwauled on some back fence in Chicago, or a Palanortis Whitewood on Venus."

She left, and Channing went with her, arguing with her to the effect that she should develop a disregard for things like their discussion. As a matter of interest, Channing had his roast knolla that evening, so he must have convinced Arden.

Walt said: "And then there were three. Christine, has our little pre-dinner talk disturbed your appetite?"

"Not in the least," said the girl stoutly. "I wouldn't care whether it was knolla or pussy cat. I've been on Mars so long that either one of the little felines is alien to me. What have you to offer?"

"We'll hit Joe's for dinner, which is the best bar in sixty million miles today. Later we may take in the latest celluloid epic, then there will be a bit of mixed wrestling in the ballroom."

"Oh, I've got on a cockeyed schedule," said Wes. "I've been catching my sleep at more and more out-of-phase hours until this is not too long after breakfast for me. You birds all speak of 'Tomorrow,' 'Today,' and 'Yesterday' out here, but this business of having no sun to come up in the morning, and the electric lights running all the time has me all bollixed up."

"That daily nomenclature is purely from habit," said Walt. "As you know, we run three equal shifts of eight hours each, and therefore what may be 'Morning' to Bill is 'Noon' to James and 'Night' to Harry. It is meaningless, but habitual to speak of 'Morning' when you mean 'Just after I get up'! Follow me?"

Walt wondered whether he should have questioned Wes about that remark, but he did not. Several hours later, he wondered how Wes could have been so right.

Venus Equilateral, Preferred, started in its long climb as soon as the markets opened on the following day. Cartwright, following his orders and his experience, held onto whatever stock he had, and bought whatever stock was tossed his way. Several times he was on the verge of asking Interplanetary Transport for monetary assistance, but the real need never materialized.

Kingman alternately cursed the whining music and cheered the pyramiding stock. About the only thing that kept Kingman from going completely mad was the fact that the alien music was not continuous, but it came and went in stretches of anything from five to fifty minutes, with varied periods for silence in between selections.

Up and up it went, and Kingman was seeing the final, victorious coup in the offing. A week more, and Venus Equilateral would belong to Terran Electric. The beam from Terra was silent, save for a few items of interest not connected with the market. Kingman's men were given the latest news, baseball scores, and so forth, among which items was another message to Channing from the solar beam project engineer, Addison. They had about given up. Nothing they could do would prevent the formation of ozone by the ton as they drew power by the kilowatt from Sol.

Ten minutes later, at the speed of light, the ship beam reached the Relay Girl and the message clicked out. Freddie read it and spoke into the microphone. The Relay Girl bucked unmercifully, as the voice amplitude made the acceleration change. Then at the speed of light, squared, the answer came back in less than a twinkle.

Channing began to turn the tuner of the radio receiver. The band was dead, and he laughed. "This is going to be tricky, what with the necessity of aligning both the driver-alloy disk and the radio receiver. Takes time."

He changed the alloy disk in minute increments, and waved the tuner across that portion of the band that would most likely cover the experimental error of Freddie Thomas' frequency measurement. A burst of sound caught his ear, was lost for a moment, and then swelled into perfect tune as Don worked over the double tuning system.

"Mine is fair," said Walt, "but it might as well be solid brass as far as this mess is concerned. It's music of some kind, you can tell it by the rhythm. But the scale isn't like anything I've ever heard before."

"I doubt it," said Channing seriously. "The swell of that orchestra indicates a number of instruments—of some cockeyed kind or other—the point I'm making is that anything of a classical or semi-classical nature played backwards on a phonograph actually sounds passable. I can't say the same for jamstead music, but it holds for most of the classics, believe it or not. This sounds strictly from hunger."

"Then they should lambaste one another with their instruments, not paste the sub-ether with them."

Channing lit a cigarette. "Mark the dial," he said. "Both of 'em. I've got to get in touch with the Thomas Boys."

Walt marked the dials and tuned for the Relay Girl. He found it coming in not far from the other setting. Chuck was speaking, and they tuned in near the middle of his speech.

"—this thing so that it will not buck like a scenic railway finding the fourth derivative of space with respect to time. For my non-technical listeners, that is none other than the better known term: Jerkiness. We applied the modulation to the first driver anode—the little circular one right above the cathode. I don't know whether this is getting out as it should, so I'm going to talk along for the next fifteen minutes straight until I hear from you. Then we're switching over and repeating. Can you hear me?"

Channing cut the gain down to a whisper and put a message on the beam, confirming his reception. Ten minutes later, Chuck changed his set speech, and said: "Good! Too bad we haven't got one of those receivers here, or we could make this a two-way with some action. Now listen, Don. My idiot brother says that he can make the beam transmit without the drive. Unfortunately, I am not a drive expert like he is and so I can not remonstrate with the half-wit. So, and right now, we're cutting the supply voltage to the final focussing anode. Whoops! I just floated off the floor and the mike cable is all tangled up in my feet. This free stuff is not as simple as the old fiction writers claimed it was. Things are floating all over the place like mad. The accelerometer says exactly zero, and so you tell me if we are getting out. We're going back on one G so that we can sit down again. That's better! Though the idiot—it's a shame to be forced to admit that one of your family is half-witted—didn't wait until we were in position to fall. I almost landed on my head—which is where he was dropped as an infant. How was it? Did you hear my manly voice whilst we were going free? Say 'No' so that my idiot brother will not have anything to say about his brilliant mind. I'm out of breath and we're going back home on that home recording of Freddie saying, and I will let him quote, via acetate."

The sound of a phonograph pick-up being dropped on a record preceded Freddie's voice saying: "One, two, three, four, test, one—"

Channing cut the gain again. "That red-hot. I thought he was talking all this time."

"Not the Thomas Boys. That comes under the classification of 'Work' which they shun unless they cannot get any kind of machine to do it for them," laughed Walt.

Walt turned the dials back to the unearthly symphony. "At C², that might come from Sirius," he said, listening carefully. "Sounds like Chinese."

"Oh, now look," objected Don. "What on earth would a Chinese Symphony be doing with a driver modulator system?"

"Nope. The idea of detecting driver radiation is as old as the hills. If any culture had uncovered driver-beam transmission we'd all have been aware of it. So far as I know, we and the Terran Electric crowd are the only ones who have had any kind of an opportunity of working with this sub-etheric energy. Wes, have you another miniature of the relay tube handy?"

"I'm going to see if this stuff can be made directional. You're bringing whatever it is into the place on a collector plate and slamming it into an input-terminal power transmission tube. It goes across the table to the relay tube, and is amplified, and then is tossed across more table to the load-terminal tube, where the output is impressed across your alloy-disk. Right?"

"I want another relay tube. I'm going to use it for a directional input-beam, aligning it in the same way that Jim Baler and Barney Carroll did their first find. The one that sucked power out of the electric light, turned off the city hall, and so on. Follow?"

"Perfectly. Yes, I've got a couple of them. But they're not connected like Walt's set-up was."

"Well, that three-tube system was built on sheer guesswork some time ago. We can tap in the relay tube and haul out a set of cables that will energize the first relay tube. Hang her on gimbals, and we'll go hunting."

"Yes. We'll have Warren's gang build us up about six of these things just as we have here."

"That won't take long," said Walt. "They're working on the tuning disks now, and we should have 'em by the time that Freddie gets back here."

Wes turned from the teletype and dug in the cabinet for the extra relay tube. He up-ended the chassis containing Walt's set-up and began to attach leads to the voltage supply, cabling them neatly and in accordance with the restrictions on lead-capacities that some of the anodes needed.

"It's alien," said Wes in agreement. "I'm going to shut it off now whilst I tinker with the tube."

"We've a Sirian Symphony," explained Don, giving Jim the background all the way to the present time. Jim listened, and then said:

"As an engineer, I've never heard anything like that in my life before. But, as a student of ancient languages and arts and sciences, I have. That's Chinese."

Channing sat down hard. He stared at the wall for minutes. "Chinese. Oh, great, slippery, green, howling catfish!" He picked up the phone and called the decoupler room where the messages were sorted as to destination upon their entry into the station.

Ben said wait a minute while he checked. He returned and said: "Four. The Lady of Cathay, The Mandarin's Daughter, The Dragoness, and The Mongol Maid. Why?"

"Put a message on each of 'em, asking whether they have any Chinese music on board."

"Make this an experimental request. If any of them are using any recordings of Chinese music, tell them to have their electronics chief replace the phonograph pick-up with a microphone—disturbing absolutely nothing—and to reply as if we could hear them: Get me?"

"Sure. Ever since we steered the Empress of Kolain out of the grease with the first station-to-ship beam, all three of the interplanetary companies have been more than willing to co-operate with any of our requests as long as we precede the message with the explanation that it's experimental. They'll do anything we ask 'em to, short of scuttling the ship."

The wailing of the music came in strong and clear. Wes turned the input tube on its support, and the music passed through a loud peak and died off on the far side to almost zero. Wes adjusted the mobile tube for maximum response and tightened a small set-screw. "It's a shame we haven't got a nice set of protractors and gimbals," said Wes. "I had to tear into the desk lamp to get that flexible pipe."

"Small loss. She's directional, all right. We'll get the gimbals later. Right now I don't want this turned off because we may hear something interesting—whoops, it went off by itself!"

Twenty minutes later, a strange voice came through the speaker. "Dr. Channing, of Venus Equilateral? We have been contacted by your organization with respect to the possibility of your being able to hear the intership communicator system. This seems impossible, but we are not ones to question. The fact that you are in possession of the facts concerning our love of the music of our ancestors is proof enough that you must have heard something. I presume that further information is desired, and I shall wait for your return. This is Ling Kai Chaing, Captain of the Lady of Cathay."

"We got it!" chortled Don. He did a war dance in the lab, and the rest followed suit. Bits of wire and oddments of one sort or another filled the air as the big, grown-up men did a spring dance and strewed the floor with daintily thrown junk. At the height of the racket, Arden and Christine entered—no, they were literally hauled in, completely surrounded, and almost smothered.

"None other. Wait, I'll get an answer." Don contacted Ben, in the decoupler room and said: "Ben, hang this line on the Lady of Cathay beam, will you?"

Don pecked out a message, "Please describe the inter-communication system used by your ship in detail. We have heard you, and you are, therefore, the first ship to contact Venus Equilateral from space flight. Congratulations."

"Dr. Channing, I am handing the microphone over to Ling Wey, our electronics engineer, who knows the system in and out. He'll work with you on this problem."

Ling Wey said: "Hello. This is great. But I'm not certain how it's done. The output of the phono system is very small, and certainly not capable of putting out the power necessary to reach Venus Equilateral from here. However, we are using a wired-radio system at seventeen hundred and ninety kilocycles in lieu of the usual cable system. The crew all like music, and, therefore, we play the recordings of our ancestral musicians almost incessantly."

He paused for breath, and Channing said: "Walt, tap out a message concerning the lead-length of the cables that supply the driver anodes. Have him check them for radio frequency pick-up."

The communication was carried on for hour after hour. Don's guess was right; the lead that connected the first driver anode was tuned in wave length to almost perfect resonance with the frequency of the wired-radio communicator system. Channing thanked them profusely, and they rang off. Soon afterward the wailing, moaning music returned to the air.

"Don't know. We can pack the juice on in the amplifier and see, now that we have it tuned on the button," said Walt.

"It won't," said Wes. "I've been all across the dial of the alloy disk. Nothing at all."

"O.K. Well, so what if it doesn't? We've still got us a ship-to-ship communications system. Hey! What was that?"

That was a pale, flat-sounding human voice saying: "Kingman! V.E. Pfd. has been at six hundred and nine for two days, now. What's our next move?"

Don fiddled with the dials for a full fifteen minutes, keeping them very close to the spot marked, hoping that Kingman's answer might not be too far out of tune. He gave up as the answer was not to be found, and returned to the original setting. Ten minutes later the voice said: "Kingman, where in the devil is my answer? I want to know what our next move is. There isn't a bit of V. E. stock available. Why don't you answer?"

Then, dimly in the background, a voice spoke to the operator of the instrument. "Kingman's probably asleep. That terrible moaning-stuff he's been complaining about makes him turn the thing off as soon as the day's market is off. He—and the rest of that crew—can't stand it. You'll have to wait until tomorrow's market opens before he'll be listening."

"Kingman!" said Don Channing. "So he's the bright guy behind this. I get it now. Somehow he discovered a detector, and he's been playing the market by getting the quotations by sub-etheric transmission at C² and beating the Northern Landing market. And did you get the latest bit of luck? Kingman still is unaware of the fact that we are onto him—and have perfected this C² transmission. Here's where he gets caught in his own trap!"

"We're not in too bad shape for making good, honest two-ways out of this sub-ether stuff. Kingman is still behind because he hasn't got a return line back to Terra—he must be using our beams, which gives us a return edge."

"That's practical. Besides, we're sitting in a great big pile of gravy right now. We can prove Kingman has been violating the law to embezzle, mulct, steal, commit grand larceny, and so on. We're going to take a swing at Mr. Kingman and Terran Electric that they won't forget. We can't lose, because I'm not a good sportsman when I find that I've been tricked. We're going after Kingman in our own fashion—and if we lose, we're going to go tinhorn and cry for the gendarmes. I'm not proud."

"We'll put a horde of folks on the decoupler files with the code of Terran Electric filed with the government offices. We can get the code, and I'm of the opinion that Kingman wouldn't take time to figure out a new code, so he'll be using the old one. As soon as we find a message in that code that is either addressed Terran Electric or pertains to V. E. Preferred stock, we'll start to intercept all such messages and use them for our own good."

"Kingman will not know we've been tricking him. Besides, we can't lose with two ways to get ahead of his one. Come on, fellows, we've got to help get the extra receivers together."

"Easy. That's where we'll use the relay stations at Luna, Deimos, and the six portables that circle Venus."

"Right. And we'd better leave a guy here to collect any more interesting messages from Kingman's crowd. We can tune it right on to Kingman's alloy, and that'll make that music take a back seat. We need narrower selectivity."

"Chuck's gang will find that if it is to be found," smiled Walt. "We're really on the track this time."

A dead-black spaceship drifted across the face of Luna slowly, and its course, though apparently aimless, was the course of a ship or a man hunting something. It darted swiftly, poised, and then zigzagged forward, each straight-side of the jagged course shorter than the one before. It passed over a small crater and stopped short.

Below, there was a spaceship parked beside a driver tube anchored in the pumice.

The black ship hovered above the parked ship, and then dropped sharply, ramming the observation dome on top with its harder, smaller bottom. The two ships tilted and fell, crushing the ground near the poised driver tube. Space-suited men assaulted the damaged ship, broke into the bent and battered plates and emerged with three men who were still struggling to get their suits adjusted properly.

Channing's men took over the poised driver tube, and in their own ship, Walt spoke over a sub-ether radio of a different type.

Don answered from Venus Equilateral, and his voice had no more delay than if he had been within a hundred yards of the crater on Luna.

"Good. Stay where you are; you can contact the Lunar Relay Station from there. Wes is all ready on Station 3 above Northern Landing with his set, and Jim Baler is at the Deimos station."

"Kingman," said Channing, with a tone of finality. "You've got your orders, Walt. When Kingman expects the market to go down, tell him it's still going up. We'll figure this out as we go along, but he won't like it at all."

There was silence for a few minutes, and then Don said: "Walt, Kingman's sent a message through to Northern Landing Station now. He says: 'Dump a block to shake the suckers loose. This is pyramided so high that they should all climb on the sell-wagon; running the market down of their own weight. When it hits a new low, we'll buy, and this time end up by having control.' When he starts to run the market down, you buy at Terra."

Minutes later, the message hit the Terra market, and Kingman's agent started to unload. The stock started off at six hundred and nine, and it soon dropped to five-forty. It hovered there, and then took another gradual slide to four-seventy. Then a message came through the regular beam station which Walt intercepted, decoded with Terran Electric's own code book, and read as follows:

Walt chuckled and spoke into the driver modulator. "Kingman," he said, "some wiseacre is still buying. V. E. Preferred is running at seven-ninety! What now?"

From Venus, Wes said: "You sure did. He's giving orders to drop more stock. This is too dirty to be funny, but Kingman asked for it. I know him. He's got this set up so that no one can do a thing on this market program without orders from him. Too bad we can't withhold the Northern Landing quotations from him."

The Lunar beam brought forth another message intended for Kingman's interceptor at Luna. "V. E. Preferred is dropping like a plummet. When can we buy?"

Walt smiled and said into Kingman's set-up: "Kingman! V. E. Preferred is now at eight hundred and seventy!"

Not many minutes later, Wes said: "That was foul, Walt. He's just given orders to run the market down at any cost."

"O.K.," said Walt. "But he's going to go nuts when the Northern Landing Exchange starts down without ever getting to that mythical nine hundred."

"Let him wonder. Meanwhile, fellows, let's run ourselves a slide on Terran Electric. Sell the works!"

Terran Electric started down just as V. E. Preferred took its third drop. It passed three hundred, and started down the two hundred numbers. Walt shook his head and said to Kingman: "Kingman, we're getting results now. She's dropped back again—to six hundred and three." Then he said: "Kingman, someone is playing hob with T. E. Preferred. She's up to two hundred and fifty-one."

To Don, Walt said: "Good thing that Kingman has that Chinese Symphony for a bit of mood music, or he'd recognize my voice."

"Which way will he jump?" laughed Don. "That was a slick bit of Kingman-baiting, Walt, in spite of your voice."

"Kingman's taking it hard," said Wes. "He says to drop some of his own stock so that they can use the money to manipulate the V. E. stuff."

"O.K.," said Jim Baler. "This looks like a good time to think about buying some of Kingman's stuff. Right?"

"Oh-oh," said Wes. "Kingman is wild. He wants to know what's the matter with the market."

"Tell him that your end is all right, and that V. E. Preferred is still going down, but steady."

The hours went by, and Kingman became more and more frantic. V. E. Preferred would be reported at five hundred, but the Northern Landing Exchange said two-ten. Meanwhile, Terran Electric—

"Oh, lovely!" said Don. "Beautiful. We've got us a reciprocating market now, better than Kingman's. When she's up at Terra, they're down at Canalopsis and Northern Landing—and vice versa. Keep it pumping, boys, and we'll get enough money to buy Kingman out."

The vacillating market went on, and Don's gang continued to rock the Terran Electric stock. Then as the market was about to close for the day, Don said: "Sell 'em short!"

Terran Electric stock appeared on the market in great quantities. Its value dropped down and down and down, and Kingman, appraised of the fall by Walt, who magnified it by not less than two to one, apparently got frantic again, for he said:

"I repeat it. Look, fellows, gather all the T. E. Preferred and V. E. Preferred you can. Walt, tell them that Terran Electric is dropping fast, so he'll scuttle more of his stuff, and we'll pick it up slowly enough so that we won't raise the market. How're we fixed for V. E. Preferred?"

"Kingman," said Walt. "Kingman! Hell's loose! The Interplanetary Bureau of Criminal Investigations has just decided to look into the matter of this stock juggling. They want to know who's trying to grab control of a public carrier!"

Minutes later, Wes said: "Oh, Brother Myrtle! That did it. He just gave orders to drop the whole thing short!"

The flurry dropped V. E. Preferred to forty-seven, and then the agents of Venus Equilateral stepped forth and offered to buy, at the market, all offered stock.

Then, as no more stock was offered, Venus Equilateral Preferred rose sharply to ninety-four and stabilized at that figure. Terran Electric stock went through a valley, made by Kingman's sales, and then headed up, made by purchases on Terra, on Mars, and on Venus.

Don said: "Look, fellows, this has gone far enough. We have control again, and a goodly hunk of Terran Electric as well. Enough, I think, to force them to behave like a good little company and stay out of other people's hair. Let's all get together and celebrate."

A month later, Joe's was the scene of a big banquet. Barney Carroll got up and said:

"Ladies and gentlemen, we all know why we're here and what we're celebrating. So I won't have to recount the whole affair. We all think Don Channing is a great guy, and Walt Franks isn't far behind, if any. I'm pretty likeable myself, and my lifelong sparring partner, Jim Baler, is no smelt either. And so on, ad nauseum.

"But, ladies and gentlemen, Don Channing has a deep, dark, dire, desperate phase of his life, one that he will be remembered and cursed for; one that will weigh about his neck like a milestone—or is it millstone?—for all of his life.

"Benefactor though he is, this much you shall know; I still say there is no place in the inner system for a man who has made this possible. Listen!"

Barney raised his hand, and an attendant turned on a standard, living room model radio receiver. It burst into sound immediately.

"Ladies and gentlemen, the Interplanetary Network now brings to you the Whitewood Nutsies Program. Karven and Norwhal, the Venusian Songbirds; Thalla; and Lillas, in person, coming to you from the jungles of Palanortis, on Venus, by courtesy of the Interplanet Foods Co. of Battle Creek, Michigan!

Christine inspected Walt carefully. Then nodded. "Yup," she grinned. "Even you sound better than the Interplanetary Network!"

Interlude:

When the final problem of communicating with a ship in space was solved, the laboratories on Venus Equilateral returned to their original trends. These lines of research and study were wide and varied. Men dabbled brilliantly with insane, complex gadgets that measured the work-functions of metals in electron emission and they made conclusive measurements on the electrical conductivity under extremes of heat and cold. From the uranium pile that powered Venus Equilateral there came metals that had been under neutron bombardment long enough to have their crystal structure altered in unfathomable ways. These were investigated by men who toyed with them to ascertain whether or not they possessed any new properties that might make them useful. Many were the fields studied, too, because it is often that a chemist may be baffled by a problem that could be solved by a thorough education in electronics, for instance.

And from the diversified studies and researches there often came strange by-products. The quick leap of the physicist from a hare-brained theory to a foregone conclusion has been the subject of laughter, but it is no less related than the chain of events that led from an exposed photographic plate to Hiroshima.

Or the chain of events that led Wes Farrell from his observation of a technician cleaning up a current-sputtered knife switch to a minor space war....

FIRING LINE

Mark Kingman was surprised by the tapping on his window pane. He thought that the window was unreachable from the outside—and then he realized that it was probably someone throwing bits of dirt or small stones. But who would do that when the doorway was free for any bell-ringer?

He shrugged, and went to the window to look out—and became crosseyed as his eyes tried to cope with a single circle not more than ten inches distant. He could see the circle—and the lands on the inside spiralling into the depths of the barrel—and a cold shiver ran up his spine from there to here. Behind the heavy automatic, a dark complected man with a hawklike face grinned mirthlessly.

"In case you require an introduction," said the hard-faced man. "I'm Allison Murdoch."

"I'm a doctor of some repute," said Hellion. "Or was, until my darker reputation exceeded my reputation for neural surgery. It was simple. I slit my arm and deposited therein the contents of a cigarette. It swelled up like gangrene and they removed me to the hospital. I removed a few guards and lit out in the ambulance. And I am here."

"Why?" Kingman then became thoughtful. "You're not telling me this for mutual friendship, Murdoch. What's on your mind?"

"The court proceedings were under question for procedure. It was further ruled that—"

"But you're capable of buying your freedom, which you did. Fundamentally, it makes no difference whether you bribe a guard to look the other way or bribe a jury to vote the other way. It's bribery in either case."

Kingman smiled in a superior way. "With the very important difference that the latter means results in absolute freedom. Bribing a guard is freedom only so long as the law may be avoided."

"I did nothing of the sort. It was a ruling over a technicality that did me the favor."

"Look," said Kingman sharply. "You didn't come here to steal by your own admission and your excellent logic. You never saw me before, and I do not know of you save what I've heard. Revenge for something real or fancied is obviously no reason for this visit. I was charged with several kinds of larceny, which charges fell through and I was acquitted of them—which means that I did not commit them. I, therefore, am no criminal. On the other hand, you have a record. You were in jail, convicted, and you escaped by some means that may have included first-degree murder. You came here for some reason, Murdoch. But let me tell you this: I am in no way required to explain the workings of my mind. If you expect me to reveal some legal machination by which I gained my freedom, you are mistaken. As far as the solar system is concerned, everything was legal and above board."

"It isn't mutual. I have no desire to be identified with a criminal of your caliber."

"It is fundamentally futile. You are not a brilliant criminal. You've been caught."

"I didn't have the proper assistance. I shall not be caught again. Look," he said suddenly, "how is your relationship with Venus Equilateral?"

"I thought so. I have a score of my own to settle. But I need your help. Do I get it?"

"You needn't threaten. I'm willing to go to any lengths to get even with Channing and his crowd. But it must be good."

"I was beaten by a technical error," explained Murdoch. "The coating on my ship did it."

"They fired at me with a super-electron gun. A betatron. It hit me and disrupted the ship's apparatus. The thing couldn't have happened if the standard space-finish hadn't been applied to the Hippocrates."

"The average ship is coated with a complex metallic oxide which among other things inhibits secondary emission. Had we been running a ship without this coating, the secondary emission would have left the Hippocrates in fair condition electrically, but Venus Equilateral would have received several times the electronic charge. But the coating accepted the terrific charge and prevented the normal urge of electrons to leave by secondary emission—"

"When an electron hits at any velocity, it drives from one to as high as fifty electrons from the substance it hits. The quantity depends upon the velocity of the original electron, the charges on cathode and anode, the material from which the target is made, and so on. We soaked 'em in like a sponge and took it bad. But the next time, we'll coat the ship with the opposite stuff. We'll take a bit of Venus Equilateral for ourselves."

"We'll try no frontal attack. Storming a citadel like Venus Equilateral is no child's play, Kingman. As you know, they're prepared for anything either legal or technical. I have a great respect for the combined abilities of Channing and Franks. I made my first mistake by giving them three days to make up their minds. In that time, they devised, tested, and approved an electron weapon of some power. Their use of it was as dangerous to them as it was to me—or would have been if I'd been prepared with a metallic-oxide coating of the proper type."

"Just what are you proposing?" asked Kingman. "I do not understand what you are getting at."

"You will be surprised to know that I handle considerable stock in that company."

"The last time you bucked them, you did it on the market. You lost," grinned Murdoch. "Proving that you haven't a hundred percent record, either. Well, while Terran Electric was dragging its par value down around the twos and threes, I took a few shares."

"I have money," said Murdoch modestly. "Plenty of it. I should have grabbed more stock, but I figured that between us we have enough to do as we please. What's your holdings?"

"I once held forty-one percent. They bilked me out of some of that. I have less than thirty percent."

"So we'll run the market crazy again, and between us we'll take off control. Then, Kingman, we'll use Terran Electric to ruin Venus Equilateral."

"Terran Electric isn't too good a company now," admitted Kingman. "The public stays away in huge droves since we bucked Venus Equilateral. That bunch of electronic screwballs has the public acclaim. They're now in solid since they opened person-to-person service on the driver frequencies. You can talk to some one in the Palanortis Country of Venus with the same quality and speakability that you get in making a call from here to the house across the street."

"Terran Electric is about finished," said Murdoch flatly. "They shot their wad and lost. You'll be bankrupt in a year and you know it."

"Terran Electric is not the mainstay of my holdings," smiled Murdoch. "Under assumed names, I have picked up quite a few bits. Look, Kingman, I'm advocating piracy!"

"Illegal piracy. But I'm intelligent. I realize that a pirate hasn't a chance against civilization unless he is as smart as they are. We need a research and construction organization, and that's where Terran Electric comes in. Its an old company, well established. It's now on the rocks. We can build it up again. We'll use it for a base, and set the research boys to figuring out the answers we need. Eventually we'll control Venus Equilateral, and half of the enterprises throughout the system."

"You run Terran Electric, and I'll run the space piracy. Between us we'll have the system over a barrel. Space craft are still run without weapons because no weapons are suited for space fighting. But the new field opened up by the driver radiation energy may exhibit something new in weapons. That's what I want Terran Electric to work on."

"We'll have to plan a bit more," said Kingman thoughtfully. "I'll cover you up, and eventually we'll buy you out. Meanwhile we'll go to work on the market and get control of Terran Electric. And plan, too. It'll have to be foolproof."

"You'll drink on it," said Murdoch. "I never touch the stuff. I still pride myself on my skill with a scalpel, and I do not care to lose it. Frankly, I hope to keep it long enough to uncover the metatarsal bones of one Donald A. Channing, Director of Communications."

Kingman shuddered. At times, murder had passed through his mind when thinking of Channing. But this cruel idea of vivisecting an enemy indicated a sadism that was far beyond Kingman's idea of revenge. Of course, Kingman never considered that ruining a man financially, reducing him to absolute dependency upon friends or government, when the man had spent his life in freedom and plenty—the latter gained by his ability under freedom—was cruel and inhuman.

And yet it would take a completely dispassionate observer to tell which was worse; to ruin a man's body or to ruin a man's life.

The man in question was oblivious to these plans on his future. He was standing before a complicated maze of laboratory glassware and a haywire tangle of electronic origin. He looked it over in puzzlement, and his lack of enthusiasm bothered the other man. Wesley Farrell thought that his boss would have been volubly glad to see the fruits of his labor.

"Go on. I'm interested even though I do not climb the chandelier and scream, beating my manly chest."

"Oil switches are cumbersome. Any other means of breaking contact is equally cumbersome if it is to handle much power. My alloy is non-arcing. It will not sustain an arc, even though the highest current and voltage are broken."

"Now I am really interested," admitted Channing. "Oil switches in a spaceship are a definite drawback."

"What's the rest of this stuff?" asked Channing, laying a hand on the glassware.

"In order to get some real voltages and currents to break without running the main station bus through here, I cooked this stuff up. The plate-grilleworks in the large tubes exhibit a capacity between them of one microfarad. Empty, that is, or I should say precisely point nine eight microfarads in vacuuo. The fluid is of my own devising, concocted for the occasion, and has a dielectric constant of thirteen times ten to the sixth power. It—"

"Great Howling Rockets!" exploded Channing. "That makes the overall capacity equal to thirteen farads!"

"Just about. Well, I have the condenser charged to three kilovolts, and then I discharge it through this switch made of the non-arcing alloy. Watch! No, Don, from back there, please, behind this safety glass."

Channing made some discomforting calculations about thirteen farads at three thousand volts and decided that there was definitely something unlucky about the number thirteen.

"The switch, now," continued Farrell, as though thirteen farads was just a mere drop in the bucket, "is opened four milliseconds after it is closed. The time-constant of the discharging resistance is such that the voltage is zero point eight three of its peak three thousand volts, giving a good check of the alloy."

"I should think so," groused Channing. "Eighty-three percent of three thousand volts is just shy of twenty-five hundred volts. The current of discharge passing through a circuit that will drop the charge in a thirteen farad condenser eighty-three percent in four milliseconds will be something fierce, believe me."

"That is why I use the heavy busbars from the condenser bank through the switch."

"I get it. Go ahead, Wes. I want to see this non-arcing switch of yours perform."

Farrell checked the meters, and then said: "Now!" and punched the switch at his side. Across the room a solenoid drove the special alloy bar between two clamps of similar metal. Almost immediately, four-thousandths of a second later, to be exact, the solenoid reacted automatically and the no-arc alloy was withdrawn. A minute spark flashed briefly between the contacts.

"And that is that," said Channing, dazed by the magnitude of it all, and the utter simplicity of the effects. "But look, Wes, may I ask you a favor? Please discharge that infernal machine and drain that electrolyte out. Then make the thing up in a tool-steel case and seal it. Also hang on busbars right at the plates themselves, and slap a peak-voltage fuse across the terminals. One that will open at anything above three thousand volts. Follow me?"

"I know," grinned Channing mopping his forehead. "The non-arc is. But that fragile glassware makes me as jittery as a Mexican jumping bean."

"Wes, if that glassware fractures somewhere, and that electrolyte drools out, you'll have a condenser of one microfarad—charged to thirteen million times three thousand volts. Or, in nice, hollow, round numbers, forty billion volts! Of course, it won't get that far. It'll arc across the contacts before it gets that high, but it might raise particular hell on the way out. Take it easy, Wes. We're seventy million-odd miles from the nearest large body of dirt, all collected in a little steel bottle about three miles long and a mile in diameter. I'd hate to stop all interplanetary communications while we scraped ourselves off of the various walls and treated ourselves for electric shock. It would—the discharge itself, I mean—raise hell with the equipment anyway. So play it easy, Wes. We do not permit certain experiments out here because of the slow neutrons that sort of wander through here at fair density. Likewise, we cannot permit dangerous experiments. And anything that includes a dangerous experiment must be out, too."

"Don't take it so hard, fella," grinned Channing. "Any time we have to indulge in dangerous experiments, we always do it with an assistant—and in one of the blister-laboratories. But take that fragile glassware out of the picture, and I'll buy it," he finished.

"Wes was just demonstrating the latest equipment in concentrated deviltry," smiled Channing.

"Oh, it's not as bad as your stuff," said Channing. "What he's got here is an alloy that will break several million watts without an arc. Great stuff, Walt."

"Sounds swell," said Walt. "Better scribble it up and we'll get a patent. It sounds useful."

"I think it may bring us a bit of change," said Channing. "It's great stuff, Wes."

"Thanks. It annoyed me to see those terrific oil-breakers we have here. All I wanted to do was to replace 'em with something smaller and more efficient."

"That's a good bet, too. We can use several fluids of various dielectric constants. Can you make solids as well?"

"Go ahead and note anything you find above the present, listed compounds and their values."

Channing led Franks from the laboratory, and once outside Channing gave way to a session of the shakes. "Walt," he said plaintively, "take me by the hand and lead me to Joe's. I need some vitamins."

"You mean that collection of cut glass?" grinned Walt. "Uh-huh. It looked as though it were about to collapse of its own dead weight!"

"That held an electrolyte of dielectric constant thirteen times ten to the sixth. He had it charged to a mere three thousand volts. Ye gods, Walt. Thirteen farads at three KV. Whew! and when he discharged it, the confounded leads that went through the glass sidewalls to the condenser plates positively glowed in the cherry red. I swear it!"

"He's like that," said Walt. "You shouldn't worry about him. He'll have built that condenser out of good stuff—the leads will be alloys like those we use in the bigger tubes. They wouldn't fracture the glass seals no matter what the temperature difference between them and the glass was. Having that alloy around the place—up in the tube maintenance department they have a half ton of quarter-inch rod—he'd use it naturally."

"I quote: 'Requiring a high voltage source of considerable current capacity, I hit upon the scheme of making a super-high capacity condenser and discharging it through my no-arc alloy. To do this it was necessary that I invent a dielectric material of K equals thirteen times ten to the sixth.' Unquote."

"Wes is a pure scientist," reminded Walt. "If he were investigating the electrical properties of zinc, and required solar power magnitudes to complete his investigation, he'd invent it and then include it as an incidental to the investigation on zinc. He's never really understood our recent divergence in purpose over the power tube. That we should make it soak up power from Sol was purely incidental and useful only as a lever or means to make Terran Electric give us our way. He'd have forgotten it, I'll bet, since it was not the ultimate goal of the investigation."

"Granted. Wes is brilliant. He is a physicist, though, and neither engineer nor inventor. I doubt that he is really interested in the physical aspects of anything that is not directly concerned with his eating and sleeping."

"That I'm against," chimed in a new voice. Arden Channing took each man by the arm and looked up on either side of her, into one face and then the other. "No matter how, why, when, who, or what, one like him is all that the solar system can stand."

"Uh-huh. You are. That's as it should be. You balance one another nicely. You couldn't use another like you. You're speaking of Wes Farrell?"

"Leave him alone," said Arden sagely. "He's good as he is. To make him similar to you would be to spoil a good man. He'd then be neither fish, flesh, nor fowl. He doesn't think as you do, but instead proceeds in a straight line from remote possibility to foregone conclusion. Anything that gets needed en route is used, or gadgeteered, and forgotten. That's where you come in, fellows. Inspect his by-products. They may be darned useful."

"I hired her," grinned Channing. "She used to make all of my stenographic mistakes, remember?"

"And gave up numerous small errors for one large one? Uh-huh, I recall. Some luck."

"Baloney. Arden, tell the truth. Didn't he threaten you with something terrible if you didn't marry him?"

Channing left the establishment known as Joe's; advertised as the "Best bar in twenty-seven million miles, minimum," and made his way to his office, slowly. He didn't reach it. Not right away. He was intercepted by Chuck Thomas, who invited him to view a small experiment. Channing smiled and said that he'd prefer to see an experiment of any kind to going to his office, and followed Chuck.

"You recall the gadget we used to get perfect tuning with the alloy-selectivity transmitter?"

"You mean that variable alloy disk all bottled up and rotated with a selsyn?" asked Don, wondering what came next. "Naturally I remember it. Why?"

"Well, we've found that certain sub-microscopic effects occur with inert objects. What I mean is this: Given a chunk of cold steel of goodly mass and tune your alloy disk to pure steel, and you can get a few micro-microamperes output if the tube is pointed at the object."

"Sounds interesting. How much amplification do you need to get this reading and how do you make it tick?"

"We run the amplifier up to the limit and then sweep the tube across the object sought, and the output meter leaps skyward by just enough to make us certain of our results. Watch!"

Chuck set the tube in operation and checked it briefly. Then he took Don's hand and put it on the handle that swung the tube on its gimbals. "Sort of paint the wall with it," he said. "You'll see the deflection as you pass the slab of tool steel that's standing there."

Channing did, and watched the minute flicker of the ultra-sensitive meter. "Wonderful," he grinned, as the door opened and Walt Franks entered.

"Nope. She's just building up some other woman's chances. Have you seen this effect?"

"That's what I like about this place," said Chuck with a huge smile. "That's approximately seven micro-microamperes output after amplification on the order of two hundred million times. We're either working on something so small we can't see it, or something so big we can't count it. It's either fifteen decimal places to the left or to the right. Every night when I go home I say a little prayer. I say: 'Dear God, please let me find something today that is based upon unity, or at least no more than two decimal places,' but it is no good. If He hears me at all He's too busy to bother with things that the human race classifies as 'One.'"

"How do you classify resistance, current, and voltage?" asked Channing, manipulating the tube on its gimbals and watching the effect.

"One million volts across ten megohms equals one hundred thousand microamperes. That's according to Ohm's Law."

"He's got the zero-madness, too," chuckled Walt. "It obtains from thinking in astronomical distances, with interplanetary coverages in watts, and celestial input, and stuff like that. Don, this thing may be handy some day. I'd like to develop it."

"I suggest that couple of stages of tube-amplification might help. Amplify it before transduction into electronic propagation."

"We can get four or five stages of sub-electronic amplification, I think. It'll take some working."

"O.K., Chuck. Cook ahead. We do not know whither we are heading, but it looks darned interesting."

"Yeah," added Walt, "it's a darned rare scientific fact that can't be used for something, somewhere. Well, Don, now what?"

"I guess we now progress to the office and run through a few reams of paper work. Then we may relax."

Hellion Murdoch pointed to the luminous speck in the celestial globe. His finger stabbed at the marker button, and a series of faint concentric spheres marked the distance from the center of the globe to the object, which Murdoch read and mentioned: "Twelve thousand miles."

"Burn it," said Murdoch. His fingers danced upon the keyboard, and high above him, in the dome of the Black Widow, a power intake tube swiveled and pointed at Sol. Coupled to the output of the power intake tube, a power output tube turned to point at the asteroid. And Murdoch's poised finger came down on the last switch, closing the final circuit.

Meters leaped up across their scales as the intangible beam of solar energy came silently in and went as silently out. It passed across the intervening miles with the velocity of light squared, and hit the asteroid. A second later the asteroid glowed and melted under the terrific bombardment of solar energy directed in a tight beam.

"It's O.K.," said Hellion. "But have the gang build us three larger tubes to be mounted turretwise. Then we can cope with society."

"What do you hope to gain by that? Surely piracy and grand larceny are not profitable in the light of what we have and know."

"I am a man of my word. I shall levy a tax against any and every ship leaving any spaceport. We shall demand one dollar solarian for every gross ton that lifts from any planet and reaches the planetary limit."

"Ironically, we'll use the Channing Layer," said Murdoch with dark humor. "Since the Channing Layer describes the boundary below which our solar beam will not work. Our reign of terror will be identified with Channing because of that; it will take some of the praise out of people's minds when they think of Channing and Venus Equilateral."

"You should recognize it," smiled Murdoch. "That's the kind of stuff you legal lights pull. Mention the accused in the same sentence with one of the honored people; mention the defendant in the same breath with one of the hated people—it's the same stunt. Build them up or tear them down by reference."

"Not at all. I've been interested for years in neurosurgery. My researches passed beyond the realm of rabbits and monkeys, and I found it necessary to investigate the more delicate, more organized, the higher-strung. That means human beings—though some of them are less sensitive than a rabbit and less delicate than a monkey." Murdoch's eyes took on a cynical expression at this. Then it passed and he continued: "I became famous, as you know. Or do you?"

"I suppose not. I became famous in my own circle. Lesser neuro-surgeons sent their complex cases to me; unless you were complex, you would never hear of Allison Murdoch. Well, anyway, some of them offered exciting opportunities. I—frankly, experimented. Some of them died. It was quite a bit of cut and try because not too much has been written on the finer points of the nervous system. But there were too few people who were complex enough to require my services, and I turned to clinical work, and experimented freely."

"No. I imagine that with many patients you exceeded your rights once too often."

"Wrong. It is a funny factor in human relationship. Something that makes no sense. When people were paying me three thousand dollars an hour for operations, I could experiment without fear. Some died, some regained their health under my ministrations. But when I experimented on charity patients, I could not experiment because of the 'Protection' given the poor. The masses were not to be guinea pigs. Ha!" laughed Murdoch, "only the rich are permitted to be subjects of an experiment. Touch not the poor, who offer nothing. Experiment upon those of intellect, wealth, fame, or anything that sets them above the mob. Yes, even genius came under my knife. But I couldn't give a poor man a fifty-fifty chance at his life, when the chances of his life were less than one in ten. From a brilliant man, operating under fifty-fifty chances for life, I became an inhuman monster that cut without fear. I was imprisoned, and later escaped with some friends."

"And that's when you stole the Hippocrates and decided that the solar system should pay you revenge money?"

"I would have done better if I had not made that one mistake. I forgot that in the years of imprisonment I fell behind in scientific knowledge. I know now that no one can establish anything at all without technical minds behind him."

"You should. Your last defeat at the hands of the technicians you scorn should have taught you a lesson. If you had been sharp, you would have outguessed them; out-engineered them. They, Kingman, were not afraid to rip into their detector to see what made it tick."

"They knew one simple thing about the universe. That rule is that if anything works once, it may be made to work again." He held up his hand as Kingman started to speak. "You'll bring all sorts of cases to hand and try to disprove me. You can't. Oh, you couldn't cause a quick return of the diplodocus, or re-enact the founding of the solar government, or even re-burn a ton of coal. But there is other carbon, there will be other governmental introductions and reforms, and there may be some day the rebirth of the dinosaur—on some planet there may be carboniferous ages now. Any phenomena that is a true phenomena—and your detector was definite, not a misinterpretation of effect—can be repeated. But, Kingman, we'll not be out-engineered again."

"And so we will have our revenge on Venus Equilateral and upon the system itself."

"Right. We want this ship fitted with the triple turret I mentioned before. Also I want the interconnecting links between the solar intake and the power-projectors beefed up. When you're passing several hundred megawatts through any system, losses of the nature of .000,000,1% cause heating to a dangerous degree. We've got to cut the I²R losses. I gave orders that the turret be started, by the way. It'll be almost ready when we return."

"Oh, yes," said Hellion Murdoch with a laugh. "Remember our last bout with the stock market? I seem to have accumulated about forty-seven percent. That's sufficient to give me control of our company."

"I still have enough left," said Murdoch quietly. "After all, I spent years in the Melanortis Country of Venus. I was working on the Hippocrates when I wasn't doing a bit of mining. There's a large vein of platiniridium there. You may answer the rest."

"That's my interest. That's my revenge! I intend to ruin Don Channing and Venus Equilateral. With the super turret they'll never be able to catch us, and we'll run the entire system."

Kingman considered. As a lawyer, he was finished. His last try at the ruination of the Venus Equilateral crowd by means of pirating the interplanetary communications beam was strictly a violation of the Communications Code. The latter absolutely prevented any man or group of men from diverting communications not intended for them and using these communications for their own purpose. His defense that Venus Equilateral had also broken the law went unheard. It was pointed out to him that Venus Equilateral tapped his own line, and the tapping of an illegal line was the act of a communications agent in the interest of the government. He was no longer a lawyer, and, in fact, he had escaped a long jail term by sheer bribery.

He was barred from legal practice, and he was barred from any business transactions. The stock market could be manipulated, but only through a blind, which was neither profitable nor safe.

His holdings in Terran Electric were all that stood between him and ruin. He was no better off than Murdoch, save that he was not wanted.

"I'm going to remain on Terra and run Terran Electric like a model company," he said. "That'll be our base."

"Right. Except for a bit of research along specified lines, you will do nothing. Your job will be to act apologetic for your misdeeds. You will grovel on the floor before any authority, and beseech the legal profession to accept you once more. I will need your help, there. You are to establish yourself in the good graces of the Interplanetary Patent Office, and report to me any applications that may be of interest. The research that Terran Electric will conduct will be along innocuous lines. The real research will be in a secret laboratory. The one in the Melanortis Country. Selected men will work there, and the Terran Electric fleet of cargo-carriers will carry the material needed. My main failure was not to have provided a means of knowing what the worlds were doing. I'll have that now, and I shall not be defeated again."

"We'll say that one together!" said Kingman. He flipped open a large book and set the autopilot from a set of figures. The Black Widow turned gently and started to run for Terra at two G.

Walt Franks frowned at the memorandum in his hand. "Look, Don, are we ever going to get to work on that deal with Keg Johnson?"

"Frankly, I don't like dabbling in stuff like that either. But Keg's an old friend, and I suppose that's how a guy gets all glommed up on projects, big business deals, and so forth. We'll be going in directly. Why the rush?"

"A bit of personal business on Mars which can best be done at the same time, thus saving an additional trip."

"O.K.," said Don idly. "Might as well get it over with. Date with Christine Baler?"

Actually, it was less than an hour before the Relay Girl went out of the South End Landing Stage, turned, and headed for Mars. Packing to the Channings was a matter of persuading Arden not to take everything but the drapes in the apartment along with her, while for Walt Franks it was a matter of grabbing a trunkful of instruments and spare parts. Space travel is a matter of waiting for days in the confines of a small bubble of steel. Just waiting. For the scenery is unchanging all the way from Sol to Pluto—and is the same scenery that can be seen from the viewports of Venus Equilateral. Walt enjoyed his waiting time by tinkering; having nothing to do would have bored him, and so he took with him enough to keep him busy during the trip.

At two Terran gravities, the velocity of the Relay Girl built up bit by bit and mile by mile until they were going just shy of one thousand miles per second. This occurred an hour before turnover, which would take place at the twenty-third hour of flight.

And at that time there occurred a rarity. Not an impossibility like the chances of collision with a meteor—those things happen only once in a lifetime, and Channing had had his collision. Nor was it as remote as getting a royal flush on the deal. It happened, not often, but it did happen to ships occasionally.

The celestial globe shimmered faintly and showed a minute point at extreme range. Automatic marker spheres appeared concentrically within the celestial globe and colures and diameters marked the globe off into octants.

Bells rang briefly, and the automatic meteor circuits decided that that object was not approaching the Relay Girl. Then they relaxed. Their work was done until another object came within range for them to inspect. They were no longer interested, and they forgot about the object with the same powers of complete oblivion that they would have exerted on a meteor of nickel and iron.

They were mechanically incapable of original thought. So the object, to them, was harmless.

Channing looked up at the luminescent spot, sought the calibration spheres, made a casual observation, and forgot about it. To him it was a harmless meteor.

Even the fact that his own velocity was a thousand miles per second, and the object's velocity was the same, coming to them on a one hundred and seventy degree course and due to pass within five thousand miles did not register. Their total velocity of two thousand miles did not register just because of that rarity with which ships pass within detector range, while meteors are encountered often.

Had Channing been thinking about the subject in earnest, he would have known—for it is only man, with all too little time, who uses such velocities. The universe, with eternity in which to work her miracle, seldom moves in velocities greater than forty or fifty miles per second.

Channing forgot it, and as the marker-spheres switched to accommodate the object, he turned to more important things.

In the other ship, Hellion Murdoch frowned. He brightened, then, and depressed the plunger that energized his solar beam and projector. He did not recognize the oncoming object for anything but a meteor, either; and his desire was to find out how his invention worked at top speeds.

"No? Look, lawyer, you're not running a job that may be given a stay or reprieve. The finders run on light velocities. The solar beam runs on the speed of light squared. We'll pass that thing at five thousand miles' distance and at two thousand miles per second velocity. A microsecond of misalignment, and we're missing, see? I think we're going to be forced to put correction circuits in so that the vector sums and velocities and distances will all come out with a true hit. It will not be like sighting down a searchlight beam at high velocity."

"Plenty, at this velocity and distance. This is the first time I've had a chance to try it out."

The latter fact saved the Relay Girl. By a mere matter of feet and inches; by the difference between the speed of light and the speed of light squared at a distance of five thousand miles, plus a slight miscompensation. The intolerably hot umbra of Murdoch's beam followed below the pilot's greenhouse of the Relay Girl all the way past, a matter of several seconds. The spill-over was tangible enough to warm the Relay Girl to uncomfortable temperatures.

Then with no real damage done, the contact with ships in space was over, but not without a certain minimum of recognition.

In the Relay Girl, Channing mopped his forehead. "That was hell itself," he said.

Arden laughed uncertainly. "I thought that it would wait until we got there; I didn't expect hell to come after us."

"I wonder," said Don honestly. "It makes a guy wonder. It was gone too fast to make certain. It probably was Solarian, but they tried to burn us with something ..."

"That makes it sound like something alien," admitted Walt. "But that doesn't make good sense."

"It makes good reading," laughed Channing. "Walt, you're the Boy Edison. Have you been tinkering with anything of lethal leanings?"

"I've toyed with the idea of coupling a solar intake beam with one of those tubes that Baler and Carroll found. Recall, they smashed up quite a bit of Lincoln Head before they uncovered the secret of how to handle it. Now that we have unlimited power—or are limited only by the losses in our own system—we could, or should be able to, make something raw-ther tough."

"Fair," grinned Walt. "I did it with miniatures only, of course, since I couldn't get my hooks on a full grown tube."

"Say," asked Arden, "how did you birds arrive at this idea so suddenly? I got lost at the first premise."

"We passed a strange ship. We heated up to uncomfortable temperatures in a matter of nine seconds flat. They didn't warm us with thought waves or vector-invectives. Sheer dislike wouldn't do it alone. I guess that someone is trying to do the trick started by our esteemed Mr. Franks here a year or so ago. Only with something practical instead of an electron beam. Honest-to-goodness energy, right from Sol himself, funnelled through some tricky inventions. What about that experiment of yours? Did you bring it along?"

Walt went to get his experiment. He returned with a tray full of laboratory glassware, all wired into a maze of electronic equipment.

"Take it easy, sport. This charges only to a hundred volts. We get thirteen hundred microfarads at one hundred volts. Then we drain off the dielectric fluid, and get one billion three hundred million volts' charge into a condenser of only one hundred micro-microfarads. It's an idea for the nuclear physics boys. I think it may tend to solidify some of the uncontrollables in the present system of developing high electron velocities."

"That thirteen million dielectric constant stuff is strictly electrodynamic, I think," said Channing. "Farrell may have developed it as a by-product, but I have a hunch that it will replace some heretofore valuable equipment. The Franks-Farrell generator will out-do Van Der Graf's little job, I think."

"Sure. He thunk up the dielectric. You thunk up the application. He won't care, and you couldn't have done it without. Follow?"

"Don't. Let it go as it is for now. It's slick, Walt, but there's no weapon in it."

"Uh-huh. Ever since Murdoch took a swing at Venus Equilateral, I've been sort of wishing that we could concoct something big enough and dangerous enough to keep us free from any other wiseacres. Remember, we stand out there like a sore thumb. We are as vulnerable as a half pound of butter at a banquet for starving Armenians. The next screwball that wants to control the system will have to control Venus Equilateral first. And the best things we can concoct to date include projectile-tossing guns at velocities less than the speed of our ships, and an electron-shooter that can be overcome by coating the ship with any of the metal-salts that enhance secondary transmission."

"Remind me to requisition a set of full-sized tubes when we return. Might as well have some fun."

"O.K., you can have 'em. Which brings us back to the present. Question: Was that an abortive attempt upon our ship, or was that a mistaken try at melting a meteor?"

"I know how to find out. Let's call Chuck Thomas and have him get on the rails. We can have him request Terran Electric to give us any information they may have on energy beams to date."

"If they write no! and we find out that they did, we'll sue 'em dead. They're too shaky to try anything deep right now."

"Right. From the station, it'll go out in print, and their answer will be on the 'type, too, since business etiquette requires it. They'll get the implication if they're on the losing end. That'll make them try something slick. If they're honest, they'll tell all."

"That'll do it all right," said Walt. "They're too shaky to buck us any more. And if they are trying anything, it'll show."

The rest of the trip was without incident. They put in at Canalopsis and found Keg Johnson with an official 'gram waiting for them. Don Channing ripped it open and read:

"Uh-huh. He feigned gangrene, was taken to the base hospital, where he raised hob in his own inimitable way. He blasted the communications set-up completely, ruined three spaceships, and made off with the fourth. The contact ship just touched there recently and found hell brewing. If they hadn't had a load of supplies and prisoners for the place, they wouldn't have known about it for months, perhaps."

"I'd bet money on it. The official report on Hellion Murdoch said that he was suffering from a persecution complex, and that he was capable of making something of it if he got the chance. He's slightly whacky, and dangerously so."

"Quite. His name is well known in the circles of neurosurgery. He is also known to be an excellent research worker in applied physics."

"Yeah, he's nuts. But only in one way, Walt. He's nuts to think that he is smarter than the entire solar system all put together. Well, what do we do now?"

"Butter ourselves well and start scratching for the answer. That betatron trick will not work twice. There must be something."

"O.K., Walt, we'll all help you think. I'm wondering how much research he had to do to develop that beam. After all, we were five thousand miles away, and he heated us up. He must've thought that we were a meteor—and another thing, too—he must've thought that his beam was capable of doing something at five thousand miles' distance or he wouldn't have tried. Ergo he must have beaten that two hundred mile bugaboo."

"We don't know that the two hundred mile bugaboo is still bugging in space," said Walt, slowly. "That's set up so that the ionization-by-products are not dangerous. Also, he's not transmitting power from station to station, et cetera. He's ramming power into some sort of beam and to the devil with losses external to his equipment. The trouble is, darn it, that we'll have to spend a month just building a large copy of my miniature set-up."

"A month is not too much time," agreed Channing. "And Murdoch will take a swing at us as soon as he gets ready to reach. We can have Chuck start building the big tubes immediately, can't we?"

"Just one will be needed. We'll use one of the standard solar intake tubes that we're running the station from. There's spare equipment aplenty. But the transmitter-terminal tube will take some building."

"Why not? Get the highest rating we can. That should be plenty. Terran probably has them in stock, and it'll save us building one."

"Tell 'em not to investigate the energy-gun idea unless they want to for their own reasons," Channing grinned. "They'll probably assume—and correctly—that we're going to tinker ourselves."

"Will do nothing since it is an extra-planetary proposition. Unless it becomes suitable for digging tunnels, or melting the Martian ice cap," laughed Channing.

Mark Kingman took the letter to Murdoch, who was hidden in the depths of the Black Widow. Hellion read it twice, and then growled.

"They smell something sure," he snarled. "Why didn't we make that a perfect hit!"

"Step up our plans. They'll have this thing in a few weeks. Hm-m-m. They order a transmitter terminal tube. Have you got any in stock?"

"Naturally. Not in stock, but available for the Northern Landing power-line order."

"You have none, then. You will have some available within a few days. That half-promise will stall them from making their own, and every day that they wait for your shipment is a day in our favor. To keep your own nose clean, I'll tell you when to ship the tube. It'll be a few days before I strike."

"I see. Those tubes are huge enough to cause comment, and there will be squibs in all papers telling of the giant tube going to Venus Equilateral, and the Sunday supplements will all break out in wild guesses as to the reason why Venus Equilateral wants a two-hundred megawatt tube. Too bad you couldn't keep your escape a secret a while longer."

"I suppose so. It was bound to be out sooner or later anyway. A good general, Kingman, is one whose plans may be changed on a moment's notice without sacrificing. We'll win through."

The days wore on, and the big turret on the top of the Black Widow took shape. The super-tubes were installed, and Murdoch worked in the bowels of the ship to increase the effectiveness of the course-integrators and to accommodate high velocities and to correct for the minute discrepancies that would crop up due to the difference in velocities between light and sub-electronic radiation.

And on Venus Equilateral, the losing end of a war of nerves was taking place. The correspondence by 'type was growing into a reasonable pile, while the telephone conversations between Terran Electric and Venus Equilateral became a daily proposition. The big tubes were not finished. The big tubes were finished, but rejected because of electrode misalignments. The big tubes were in the rework department. The big tubes were on Luna for their testing. And again they were rejected because the maximum power requirements were not met. They were returned to Evanston and were once more in the rework department. You have no idea how difficult the manufacture of two-hundred megawatt tubes really is.

So the days passed, and no tubes were available. The date passed which marked the mythical date of 'if'—If Venus Equilateral had started their own manufacturing on the day they were first ordered from Terran Electric, they would have been finished and available.

Then, one day, word was passed along that the big tubes were shipped. They were on their way, tested and approved, and would be at Venus Equilateral within two days. In the due course of time, they arrived, and the gang at the relay station went to work on them.

The news of Murdoch's first blow came that day. It was a news report from the Interplanetary Network that the Titan Penal Colony had been attacked by a huge black ship of space that carried a dome-shaped turret on the top. Beams of invisible energy burned furrows in the frozen ground, and the official buildings melted and exploded from the air pressure within them. The Titan station went off the ether with a roar, and the theorists believed that Murdoch's gang had been augmented by four hundred and nineteen of the Solar System's most vicious criminals.

"That rips it wide open," said Channing. "Better get the folks to withstand a siege. I don't think they can take us."

"With the sub-electron beams we now have, he could do it on a mere piece of the station. Not perfectly, but he'd get along."

"Fine future," gritted Channing. "This is a good time to let this project coast, Walt. We've got to start in from the beginning and walk down another track."

"I know it. So far, all we've been able to do is take energy from the solar intake beams and spray it out into space. It goes like the arrow that went—we know not where."

"Forget these gadgets. Have Chuck hook up the solar intake tubes to the spotter and replace the cathodes with pure thorium. I've got another idea."

Channing laughed. "We'll stalemate him," he said bitterly, and explained to Walt. "I wonder when Murdoch will come this way?"

"It's but a matter of time," said Walt. "My bet is as soon as he can get here with that batch of fresh rats he's collected."

Walt's bet would have collected. Two days later, Hellion Murdoch flashed a signal into Venus Equilateral and asked for Channing.

"Hello, Hellion," answered Channing. "Haven't you learned to keep out of our way?"

"Not at all," answered Murdoch. "You won't try that betatron on me again. This ship is coated with four-tenths of an inch of lithium metal, which according to the books will produce the maximum quantity of electrons under secondary emission. If not the absolute maximum, it is high enough to prevent your action."

"No," agreed Channing. "We won't try the betatron again. But, Murdoch, there are other things."

"Can they withstand these," asked Murdoch. The turret swiveled until the triple-mount of tubes looked at Venus Equilateral.

"You're either guessing, or hoping I won't fire, or perhaps praying that whatever you have for protection will work," said Murdoch flatly. "Otherwise you wouldn't talk so smooth."

"You black-hearted baby-killing rotter," snarled Don Channing. "I'm not chinning with you for the fun of it. You'll shoot anyway, and I want to see how good you are. Get it over with, Murdoch."

"What I have here is plenty good," said Murdoch. "Good enough. Do you know about it?"

"We may not be able to outfire you," gritted Channing, "but we may be able to nullify your beam."

"Oh, no. We'll just shoot your little station full of holes. Like the average spaceship, your station will be quite capable of handling communications even though the air is all gone. Filling us full of holes wouldn't do a thing; you see, we're wearing spacesuits."

"I guessed that. No, Murdoch, we have nothing to shoot at you this time. All we can do is hold you off until you get hungry. You'll get hungry first, since we're self-sufficient."

"In the meantime we're going to try a few things out on your hull. I rather guess that you'll try out a few things on the station. But at the present, you can't harm us and we can't harm you. Stalemate, Murdoch!"

"Are you afraid to squirt that beam this way?" asked Channing tauntingly. "Or do you know it will not work?"

"We're very practical, out here on Venus Equilateral," said Don. "There's no use in our working further if you have something that is really good. We'd like to know our chances before we expend more effort along another line."

"No. Frankly, I'm almost certain that your beam won't do a thing to Venus Equilateral."

The lights in Venus Equilateral brightened. The thousands of line-voltage meters went from one hundred and twenty-five to one hundred and forty volts, and the line-frequency struggled with the crystal-control and succeeded in making a ragged increase from sixty to sixty point one five cycles per second. The power-output meters on the transmitting equipment went up briefly, and in the few remaining battery-supply rooms, the overload and overcharge alarms clanged until the automatic adjusters justified the input against the constant load. One of the ten-kilowatt modulator tubes flashed over in the audio-room and was immediately cut from the operating circuit; the recording meters indicated that the tube had gone west forty-seven hours prior to its expiration date due to filament overload. A series of fluorescent lighting fixtures in a corridor of the station that should have been dark because of the working hours of that section flickered into life and woke several of the workers, and down in the laboratory, Wes Farrell swore because the fluctuating line had disrupted one of his experiments, giving him reason to doubt the result. He tore the thing down, and began once more; seventy days' work had been ruined.

"You forgot," reminded Channing, "that we have been working with solar power, too. In fact, we discovered the means to get it. Go ahead and shoot at us, Murdoch. You're just giving us more power."

"Oh, don't," cheered Don. "You forgot that those tubes, if aligned properly, will actually cause bending of the energy-beam. We've got load-terminal tubes pointing at you, and your power beam is bending to enter them. You did well, though. You were running the whole station with plenty to spare. We had to squirt some excess into space. Your beams aren't worth the glass that's in them!"

"Stalemate, then," snarled Murdoch. "Now you come and get us. We'll leave. But we'll be back. Meanwhile, we can have our way with the shipping. Pilot! Course for Mars! Start when ready!"

The Black Widow turned and streaked from Venus Equilateral as Don Channing mopped his forehead. "Walt," he said, "that's once I was scared to death."

Farrell entered and said: "They broke up my job. I had to set it up again, and I'm temporarily free. Anything I can do to help?"

Farrell laughed. "That's problematical. Energy guns are something strange. Their output can be trapped and used to good advantage. What you need is some sort of projectile, I think."

"Obviously the normal kinds are useless. Fragmentation shells would pelt the exterior of the hull with metallic rain—if and providing you could get them that close. Armor-piercing would work, possibly, but their damage would be negligible since hitting a spacecraft with a shell is impossible if the ship is moving at anything at all like the usual velocities. Detonation shells are a waste of energy, since there is no atmosphere to expand and contract. They'd blossom like roses and do as much damage as a tossed rose."

"If you could build a super-heavy fragmentation and detonation shell, and combine it with armor-piercing qualities, and could hit the ship, you might be able to stop them. You'd have to pierce the ship, and have the thing explode with a terrific blast. It would crack the ship because of the atmosphere trapped in the hull—and should be fast enough to exceed the compressibility of air. Also it should happen so fast that the air leaving the hole made would not have a chance to decrease the pressure. The detonation would crack the ship, and the fragmentation would mess up the insides to boot, giving two possibilities. But if both failed and the ship became airless, they would fear no more detonation shells. Fragments would always be dangerous, however."

"More than that. The meteor-circuits would intercept the incoming shell and it would never get there. What you'd need is a few hundred pounds of 'window.' You know, strips of tin foil cut to roughly a quarter-wave length of the meteor detecting radar. That'll completely foul up his directors and drive-couplers. Then the big one, coming in at terrific velocity."

"And speaking of velocity," said Walt Franks, "the projectile and the rifle are out. We can get better velocity with a constant-acceleration drive. I say torpedoes!"

"Naturally. But the aiming? Remember, even though we crank up the drive to fifty G, it takes time to get to several thousand miles per second. The integration of a course would be hard enough, but add to it the desire of men to evade torpedoes—and the aiming job is impossible."

"We may be able to aim them with a device similar to the one Chuck Thomas is working with. Murdoch said his hull was made with lithium?"

"Well. Set the alloy-selectivity disk to pure lithium, and use the output to steer the torpedo right down to the bitter end."

"Nope. At those velocities, impact would cause detonation, the combined velocities would look like a detonation wave to the explosive. After all, darned few explosives can stand shock waves that propagate through them at a few thousand miles per second."

"Not a chance," grinned Channing. "The next time we meet up with Hellion Murdoch, he'll have absorbers ready for use. We taught him that one, and Murdoch is not slow to learn."

"Then I've got it! We mount two electrodes of the non-arcing alloy in front. Make 'em heavy and of monstrous current carrying capacity. Then we connect them to a condenser made of Farrell's super-dooper dielectric."

"You bet," said Walt grinning. "We put a ten microfarad condenser in front, only it'll be one hundred and thirty farads when we soak it in Farrell's super-dielectric. We charge it to ten thousand volts, and let it go."

"We've got a few experimental jobs," said Channing. "Those inerts. The drones we were using for experimental purposes. They were radio controlled, and can be easily converted to the aiming circuits."

"Hm-m-m. Remind me to quit Saturday," said Walt. "I wonder how a ten farad condenser would drive one of those miniatures...."

"Why not mount one of the miniatures on a gunstock and put a ten farad condenser in the handle. Make a nice side arm."

"Good for one shot, and not permanently charged. You'd have to cut your leakage down plenty."

"Could be. Well, we'll work on that one afterwards. Let's get that drone fixed."

"Let's fix up all the drones we have. And we'll have the boys load up as many as they can of the little message canisters with the windows. The whole works go at once with the same acceleration, with the little ones running interference for the big boy."

"Murdoch invited us to 'come and get him'," said Channing in a hard voice. "That, I think we'll do!"

Four smouldering derelicts lay in absolute wreckage on or near the four great spaceports of the solar system. Shipping was at an unequalled standstill, and the communications beams were loaded with argument and recriminations and pleas as needed material did not arrive as per agreement. Three ships paid out one dollar each gross ton in order to take vital merchandise to needy parties, but the mine-run of shipping was unable to justify the terrific cost.

And then Don Channing had a long talk with Keg Johnson of Interplanetary Transport.

One day later, one of Interplanetary's larger ships took off from Canalopsis without having paid tribute to Murdoch. It went free—completely automatic—into the Martian sky and right into Murdoch's hands. The pirate gunned it into a molten mass and hurled his demands at the system once more, and left for Venus, since another ship would be taking off from there.

In the Relay Girl, Don Channing smiled. "That finds Murdoch," he told Walt. "He's on the standard course for Venus from Mars."

"Bright thinking," commented Walt. "Bait him on Mars and then offer him a bite at Venus. When'll we catch him?"

"He's running, or will be, at about three G, I guess. We're roaring along at five and will pass Mars at better than four thousand miles per second. I think we'll catch and pass the Black Widow at the quarter-point, and Murdoch will be going at about nine hundred miles per. We'll zoom past, and set the finder on him, and then continue until we're safely away. If he gets tough, we'll absorb his output, though he's stepped it up to the point where a spacecraft can't take too much concentrated input."

"Right. The stuff on the station was adequate to protect but an ordinary ship couldn't handle it unless the ship were designed to absorb and dissipate that energy. The beam-tubes would occupy the entire ship, leaving no place for cargo. Result: A toss-up between paying off and not carrying enough to make up the difference."

"This is Freddie," spoke the communicator. "The celestial globe has just come up with a target at eight hundred thousand miles."

"Hold it," said Walt. "Our velocity with respect to his is about three thousand. We can be certain of the ship by checking the finder-response on the lithium coating. If so, she's the Black Widow. Right from here, we can be assured. Jim! Check the finders in the torpedoes on that target!"

"Freddie, drop two of the torpedoes and half the 'window.' Send 'em out at ten G. We'll not put all our eggs in one basket," Channing said to Walt. "There might be a slip-up."

"That explosive will be as useless as a slab of soap," said Don. "Explosive depends for its action upon velocity—brother, there ain't no explosive built that will propagate at the velocity of our torpedo against Murdoch."

"Then yell," grinned Walt. "Look, Don, this should be pretty. Let's hike to the star-camera above and watch. We can use the double-telescope finder and take pix, too."

"It won't be long," said Channing grimly. "And we'll be safe, since the interferers will keep Murdoch's gadget so busy he won't have time to worry us. Let's go."

The sky above became filled with a myriad of flashing spots as the rapidly-working meteor spotters coupled to the big turret and began to punch at the interferers.

The clangor of the alarm made Murdoch curse. He looked at the celestial globe and his heart knew real fear for the first time. This was no meteor shower, he knew from the random pattern. Something was after him, and Murdoch knew who and what it was. He cursed Channing and Venus Equilateral in a loud voice.

It did no good, that cursing. Above his head, the triply mounted turret danced back and forth, freeing a triple-needle of Sol's energy. At each pause another bit of tinfoil went out in a blaze of fire. And as the turret destroyed the little dancing motes, more came speeding into range to replace them, ten to one.

And then it happened. The finder-circuit fell into mechanical indecision as two of the canisters of window burst at angles, each with the same intensity. The integrators ground together, and the forces they loosed struggled for control.

Beset by opposing impulses, the amplidyne in the turret stuttered, smoked, and then went out in a pungent stream of yellowish smoke that poured from its dust-cover in a high-velocity stream. The dancing of the turret stopped, and the flashing motes in the sky stopped with the turret's death.

One hundred and thirty farads, charged to ten thousand volts, touched the lithium-coated, aluminum side of Murdoch's Black Widow. Thirteen billion joules of electrical energy; thirty-six hundred kilowatt hours went against two inches of aluminum. At the three thousand miles per second relative velocity of the torpedo, contact was immediate and perfect. The aluminum hull vaporized under the million upon million of kilovolt-amperes of the discharge. The vaporized hull tried to explode, but was hit by the unthinkable velocity of the torpedo's warhead.

The torpedo itself crushed in front. It mushroomed under the millions of degrees Kelvin developed by the energy-release caused by the cessation of velocity. For at this velocity the atmosphere within the Black Widow was as immobile and as hard as tungsten steel at its best.

The very molecules themselves could not move fast enough. They crushed together and in compressing brought incandescence.

The energy of the incoming torpedo raced through the Black Widow in a velocity wave that blasted the ship itself into incandescence. In a steep wave-front, the vaporized ship exploded in space like a super-nova.

It blinded the eyes of those who watched. It overexposed the camera film and the expected pictures came out with one single frame a pure, seared black. The piffling, comparatively ladylike detonation of the System's best and most terrible explosive was completely covered in the blast.

Seconds later, the Relay Girl hurtled through the sky three thousand miles to one side of the blast. The driven gases caught the Girl and stove in the upper observation tower like an eggshell. The Relay Girl strained at her girders, and sprung leaks all through the rigid ship, and after rescuing Don Channing and Walt Franks from the wreckage of the observation dome, the men spent their time welding cracks until the Relay Girl landed.

It was Walt who put his finger on the trouble. "That was period for Murdoch," he said. "But Don, the stooge still runs loose. We're going to be forced to take over Mark Kingman before we're a foot taller. He includes Terran Electric, you know. That's where Murdoch got his machine work done."

"Without Murdoch, Kingman is fairly harmless," said Don, objecting. "We'll have no more trouble from him."

"You're a sucker, Don. Kingman will still be after your scalp. You mark my words."

"Nothing for the present. I've still got that date with Christine at Lincoln Head. Mind?"

Interlude:

Not all inventions and discoveries need be deadly. Yet if the matter is considered deeply enough, inventions and discoveries are, in a sense, deadly to something. The automobile sounded the knell of the blacksmith. Gutenberg stopped the widespread trade of the official scribes, who spent their working day writing books by hand.

It is also quite safe to assume that inventors themselves seldom realize the effect their contributions will have upon the future. Did the Wright brothers ever stand upon that hill near Dayton, Ohio, where they flew box kites, and believe that within the span of a lifetime that hill would be surrounded on all sides by the solid acres of land that now bears their name: Wright Field? Did James Clerk Maxwell, in postulating his Electromagnetic Equations, ever conceive of the massive industry that was to grow around the art of radio transmission? Did Thomas Alva Edison contemplate Times Square when he was seeking a more efficient means of illumination?

Yes, inventions are all deadly in one sense or another. They are openly considered so when their effect kills human beings. Few inventions are conceived with the intent of producing murder, the atomic bomb notwithstanding.

THAT little fiendish device was the accumulation of knowledges and sciences gathered by men who were seeking knowledge for the sake of knowledge and it was not until the need arose and the facts became clear that the idea of Atomic Power for Military Purposes became fact.

Similarly, Walt Franks didn't really know what he was starting when he began to think about the next big project for Venus Equilateral.

You see, by reasoning, Walt assumed that if men could send intelligence and energy by beam transmission, there was no reason why men couldn't send—THINGS.

SPECIAL DELIVERY

Don Channing grinned at his wife knowingly. Arden caught his glance and then laughed. Walt Franks leaned back and looked highly superior. "Go ahead and laugh, darn you. I tell you it can be done."

"Walt, ever since you tried that stunt of aerating soap with hydrogen to make a floating soap for shower baths, I've been wondering about your kind of genius."

"It would come in handy if possible," remarked Don. "At slightly under two G, it takes only four hours to make Luna from Terra. On the other hand, shipping stuff from Melbourne, Australia, to New York City, or to the Mojave spaceport takes considerably longer. Spacecraft as super stratosphere carriers aren't too good, because you've got to run in a circle. In space you run at constant acceleration to mid-point and then decelerate the rest of the way. Fine for mile-eating, but not too hot for cutting circles."

"Well," said Walt, pencilling some notes on the tablecloth, "it's like this. The Carroll-Baler power-transmission tube will carry energy. According to their initial experiments, they had some trouble."

"No matter of importance," said Don. "I think I know what you mean. He hit the intake end—or tried to. The hammer was cut neatly and precisely off, and the energy of the blow was transmitted, somehow, to the wall."

"Through the wall," corrected Walt. "It cracked the plaster, but it went through so fast that it merely cracked it. The main blow succeeded in breaking the marble facade of the city hall."

"A tube which scans matter, atom by atom, line by line and plane by plane. The matter is removed, atom by atom, and transmitted by a sort of matter bank in the instrument."

"Matter bank," said Walt. "We can't transmit the stuff itself. That's out. We can't dissipate the atomic energy or whatever effect we might get. We can establish a balance locally by using the energy release to drive the restorer. According to some initial experiments, it can be done. We take something fairly complex and break it down. We use the energy of destruction to re-create the matter in the bank, or solid block of local stuff. Let it be a mass of stuff if it wants to, at any rate, the signal impulses from the breakdown will be transmitted, scanned if you will, and transmitted to a receiver which reverses the process. It scans, and the matter bank is broken down and the object is reconstructed."

"I hope we can get free and unrestricted transmutation," offered Don. "You can't send a steel spring out and get one back made of copper."

"Darling," drawled Arden, "don't you think you'd better catch your rabbit first?"

"A couple. I've been tinkering a bit. I know we can disintegrate matter through a power-tube of slight modification, and reintegrate it with another. At the present state of the art, it is a mess."

"A nice mess," laughed Don. "Go ahead, though. We'll pitch in when the going gets hard."

"Getting a perfect focus. I want it good enough so that we can scan a polished sheet of steel—and it'll come out as slick as the original."

"Look, Walt. Quit hoping. If you get this thing running right, it'll put your name in history."

"After all," grinned Walt, "I've got to do something good enough to make up for that Channing Layer."

"Kingman is still fuming over the Channing Layer. Sometimes I feel sorry that I did it to him like that."

"Wasn't your fault, Don. You didn't hand him the thing knowing that the Channing Layer would inhibit the transmission of energy. It happened. We get power out of Sol—why shouldn't they? They would, except for the Channing Layer."

"About the Channing Layer? Maybe your spaceline competition is not as good as it sounds."

"Well, they use the power-transmission tubes all over the face of the Solar System. I can't see any reason why they couldn't ship stuff from Sydney to Mojave and then space it out from there."

"What an itinerary! By Franks' matter transmitter to Mojave. Spacecraft to Luna. More matter transmission from Luna to Phobos. Then trans-shipped down to Lincoln Head, and by matter transmitter to Canalopsis. Whoosh!"

"Do we have time to go into the old yarn about the guy who listened in and got replicas?" asked Arden.

"That's a woman's mind for you," grinned Channing. "Always making things complicated. Arden, my lovely but devious-minded woman, let's wait until we have the spry beastie by the ears before we start to make rabbit pie."

"It's not as simple as it sounds," warned Walt. "But it's there to worry about."

"Wonderful is the mind of woman," praised Don. "Positively wonderful! Arden, you have earned your next fur coat. Here I've been thinking of radio transmission all this time. No, Arden, when you're set up for sheer energy transmission, it's strictly no dice. The crimped up jobs we use for communications can be tapped—but not the power transmission beams. If you can keep the gadget working on that line, Walt, we're in and solid."

"Let Kingman try and find a precedent for that. Brother Blackstone himself would be stumped to make a ruling. We'll have to go to work with the evidence as soon as we get a glimmer of the possibilities. But I think we have a good chance. We can diddle up the focus, I'm certain."

Arden glowered. "Go ahead—have your fun. I see another couple of weeks of being a gadgeteer's widow." She looked at Walt Franks. "I could stand it if the big lug only didn't call every tool, every part, and every effect either she or baby!"

Walt grinned. "I'd try to keep you from being lonely, but I'm in this, too, and besides, you're my friend's best wife."

"Shall we drag that around a bit? I think we could kill a couple of hours with it sometime."

"Let it lie there and rot," snorted Channing cheerfully. "We'll pick it up later. Come on, Walt. We've got work to do."

Mark Kingman glowered at the 'gram and swore under his breath. He wondered whether he might be developing a persecution complex; it seemed as though every time he turned around, Venus Equilateral was in his hair, asking for something or other. And he was not in any position to quibble about it. Kingman was smart enough to carry his tray very level. Knowing that they were waiting for a chance to prove that he had been connected with the late Hellion Murdoch made him very cautious. There was no doubt in any mind that Murdoch was written off the books, but whether Murdoch had made a sufficiently large impression on the books of Terran Electric to have the connection become evident—that worried Kingman.

So he swore at each telegram that came in, but quietly, and followed each request to the letter. Compared to his former attitude toward Venus Equilateral, Mark Kingman was behaving like an honor student in a Sunday school.

He punched the buzzer, told his secretary to call in the shop foreman, and then sat back and wondered about the 'gram.

He was still wondering when the man entered. Kingman looked up and fixed his superintendent with a fishy glance. "Horman, can you guess why the Venus Equilateral crowd would want two dozen gauge blocks?"

"Channing wants twenty-four blocks. All three inches on a side—cubes. Square to within thirty seconds of angle, and each of the six faces optically flat to one-quarter wave length of cadmium light."

"Whoosh!" said Horman. "I presume the three-inch dimension must be within a half wave length?"

"We're running over thin ice," said Kingman reflectively. "I can't afford to play rough. We'll make up their blocks."

"Not unless they're just being difficult. You don't put primary blocks on any production line. You make secondary gauges for production line use and keep a couple of primaries in the check room to try the secondaries on. In fact, you usually have a whole set of gauge blocks to build up to any desired dimension so that you don't have to stock a half-million of different sizes."

"Possible," said Horman slowly. "But not too probable. On the other hand, I may be one hundred percent wrong. I don't know all the different stuff a man can make, by far. My own experience indicates that nothing like that would be needed. But that's just one man's experience."

"Channing and that gang of roughneck scientists have been known to make some fancy gadgets," said Kingman grudgingly.

"If you'll pardon my mentioning the subject," said Horman in a scathing tone, "you'd have been far better off to tag along with 'em instead of fighting 'em."

"I'm not too bad off. I've come up from the Chief Legal Counsel of Terran Electric to controlling the company."

"And Terran Electric has slid down from the topmost outfit in the system to a seventh rater."

"We'll climb back. At any rate, I'm better off personally. You're better off personally. In fact, everybody that had enough guts to stay with us is better off."

"Yeah—I know. It sounds good on paper. But make a bum move again, Kingman, and we'll all be in jail. You'd better forget that hatred against Venus Equilateral and come down to earth."

"Well, I've been a good boy for them once. After all, I did point out the error in their patent on the solar beam."

"Frankly, it was a minor error. It's one of those things that is easy to get caught on. You know how it came about?"

"Nope. I accepted it just like everybody else. It took some outsider to laugh at me and tell me why."

Kingman smiled. "It's easy to get into easy thinking. They took power from Sirius—believe it or not—and then made some there-and-back time measurements and came up with a figure that was about the square of one hundred eighty-six thousand miles per second. But you know that you can't square a velocity and come up with anything that looks sensible. The square of a velocity must be some concept like an expanding area."

"Or would it be two spots diverging along the sides of a right angle?" queried Horman idly. "What was their final answer?"

"The velocity of light is a concept. It is based on the flexibility of space—its physical constants, so to speak. Channing claims that the sub-etheric radiation bands of what we have learned to call the driver radiation propagates along some other medium than space itself. I think they were trying to establish some mathematical relation—which might be all right, but you can't establish that kind of relation and hope to hold it. The square of C in meters comes out differently than the square of C in miles, inches, or a little-used standard, the light-second, in which the velocity of light is unity, or One. Follow? Anyway, they made modulation equipment of some sort and measured the velocity and came up with a finite figure which is slightly less than the square of one hundred eighty-six thousand miles per second. Their original idea was wrong. It was just coincidence that the two figures came out that way. Anyway," smiled Kingman, "I pointed it out to them and they quick changed their patent letters. So, you see, I've been of some help."

"Nice going. Well, I'm going to make those gauges. It'll take us one long time, too. Johannson Blocks aren't the easiest things in the world to make."

"We use glass gauges, mostly. They don't dinge or bend when dropped—they go to pieces or not at all. We can't have a bent gauge rejecting production parts, you know, and steel gauges can be bent. Besides, you can grind glass to a half wave length of light with ease, but polishing steel is another item entirely."

"I'm going to call Channing and ask him about glass blocks. It may be that he might use them. Plus the fact that I may get an inkling of the ultimate use. They have no production lines running on Venus Equilateral, have they?"

Kingman's voice raced across Terra to Hawaii, went on the communications beams of the sky-pointing reflectors, and rammed through the Heaviside Layer to Luna. At the Lunar Station, his voice was mingled in multiplex with a thousand others and placed on the sub-ether beams to Venus Equilateral.

Don grunted. He did not like to be addressed by title when someone who disliked him did it. His friends did not; Kingman's use of the title made it an insult.

"Our tool shop is nicely equipped to grind glass gauges. We can do that better than grinding Jo-blocks. Can you use glass ones?"

"Hang on a minute." Channing turned to Walt. "Kingman says his outfit uses glass gauges. Any reason why we can't?"

"See no reason why not. I've heard of using glass gauges, and they've got some good reasons, too. Tell him to go ahead."

"We'll have your blocks on the way within four days, Channing. Four days minimum, plus whatever wait is necessary to get 'em aboard a spacer."

"We'll check from this end on schedules. We need the blocks, and if the wait is too long, we'll send the Relay Girl in for 'em."

Don hung up and then said: "Glass ones might be a good idea. We can check the transmission characteristics optically. I think we can check more, quicker, than by running analysis on steel."

"Plus the fact that you can get the blocks back after test," grinned Walt. "Once you tear into a steel block to check its insides, you've lost your sample. I don't know any better way to check homogeneity than by optical tests."

"O.K. Well, four days for glass blocks will do better than a couple of months on steel blocks."

They found Farrell in one of the blister laboratories, working on a small edition of the power transmission tubes. He was not dressed in spacesuit, and so they entered the blister and watched him work.

"Have a little trouble getting the focus to stay sharp through the trace," complained Wes. "I can get focus of atomic proportions—the circle of confusion is about the size of the atom nucleus, I mean—at the axis of the tube. But the deflection of the cone of energy produces aberration, which causes coma at the edges. The corners of an area look fierce."

"It would be nice—but no more fantastic than this thing is now. What's your opinion?"

Wes loosened a set screw on the main tube anode and set the anode forward a barely perceptible distance. He checked it with a vernier rule and tightened the screw. He made other adjustments on the works of the tube itself, and then motioned outside. They left the blister, Wes closed the air-tight, and cracked the valve that let the air out of the blister. He snapped the switch on the outside panel and then leaned back in his chair while the cathode heated.

"With electrical scanning, you'll have curvature of field with this gadget. That isn't too bad, I suppose, because the restorer will have the same curvature. But you're going to scan three ways, which means correction for the linear distance from the tube as well as the other side deflections and their aberrations. Now if we could scan the gadget mechanically, we'd have absolute flatness of field, perfect focus, and so forth."

Walt grinned. "Thinking of television again? Look, bright fellows, how do you move an assembly of mechanical parts in quanta of one atomic diameter? They've been looking for that kind of a gadget for centuries. Dr. Rowland and his gratings would turn over in their graves with a contrivance that could rule lines one atom apart."

"If it would rule one atom lines, brother, you could put a million lines per inch on anything rulable with perfection, ease, eclat, and savoir faire. You follow my argument? Or would you rather take up this slip of my tongue and make something out of it?"

Wes Farrell grinned. "Looks like I'd better be getting perfect focus with the electrical system here. I hadn't considered the other angle at all, but it looks a lot tougher than I thought."

He squinted through a wall-mounted telescope at the set-up on the inside of the blister. "She's hot," he remarked quietly, and then set to checking the experiment. Fifteen minutes of checking, and making notes, and he turned to the others with a smile. "Not too bad that way," he said.

"I've established a rather complex field. In order to correct the aberrations, I've got non-linear focussing fields in the places where they tend to correct for the off-axis aberrations. To correct for the height-effect, I'm putting a variable corrector to control the whole cone of energy, stretching it or shortening it according to the needs. I think if I use a longer focal length I'll be able to get the thing running right.

"That'll lessen the need for correction, too," he added, cracking the blister-intake valve and letting the air hiss into the blister. He opened the door and went inside, and began to adjust the electrodes. "You know," he added over his shoulder, "we've got something here that might bring a few dollars on the side. This matter-bank affair produces clean, clear, and practically pure metal. You might be able to sell some metal that was rated 'pure' and mean it."

"You mean absolutely, positively, guaranteed, uncontaminated, unadulterated, perfectly chemically pure?" grinned Don.

"Compared to what 'chemically pure' really means, your selection of adjectives is a masterpiece of understatement," laughed Walt.

"I'm about to make one more try," announced Wes. "Then I'm going to drop this for the time being. I've got to get up to the machine shop and see what they're doing with the rest of the thing."

"Will you? I'll appreciate it. I sort of hate to let this thing go when I feel that I'm near an answer."

They left the laboratory and made their way to the elevator that would lift them high into the relay station where the machine shop was located. As they entered the elevator Don shook his head.

"Well, friend Wes is on the beam again. If he feels that we're close to the answer, I'll bet a hat that we're hanging right on the edge. Also, that kind of work would kill me dead. He likes to stick on one thing till the bitter end, no matter how long it takes. I couldn't do it."

"I know. About three days of this and you're wanting another job to clear your mind. Then you could tackle that one for about three hours and take back on the first."

"Trying to do that to Farrell would kill both him and the jobs," said Don. "But you and I can keep two or three projects going strong. Oh, well, Wes is worth a million."

"He's the best we've got," agreed Walt. "Just because he has a peculiar slant on life is no sign he's not brilliant."

"It's you and I that have the cockeyed slant on life," grinned Don. "And frankly, I'm proud of it." He swung the elevator door aside and they walked down the corridor. "This isn't going to be much to see, but we'll take a look."

The machine shop, to the man, was clustered around the one cabinet under construction. They moved aside to permit the entry of Channing and Franks.

It did. It stood five feet tall, three feet square, and was sealed in front by a heavy door. There was a place intended for the tube that Farrell was tinkering in the blister, and the lines to supply the power were coiled behind the cabinet.

"Just the power circuits," answered Warren, "We'll have this finished in a couple of days now. The other one is completed except for Wes Farrell's section."

Channing nodded, and said: "Keep it going." He turned to Walt and after the passage of a knowing glance the pair left. "Walt, this is getting on my nerves. I want to go down to Joe's and drink myself into a stupor which will last until they get something cogent to work on."

"I'm going to get Arden. Self-protection. She'd cut my feet off at the knees if I went off on a tear without her."

"If and when. If you two go on as you have for another year without one of you turning up with a black eye, I may be tempted to go forth and track me down a babe of my own."

The cabinet stood in the north end of Venus Equilateral but it was not alone. It may even be the record for all times; certainly no other cabinet three by three by five ever had twenty-seven men all standing in a circle awaiting developments. The cabinet at the south end of Venus Equilateral was no less popular, though the number of watchers was less by one. Here, then, were winner and runner-up of inanimate popularity for the ages. The communicator system set in the walls of the two rooms carried sounds from the north room to the south, and those sounds in the south room could be heard in the north room. Channing grinned boyishly at Arden.

"This, my love, is a device which may make it quite possible for me to send you back to mother."

Arden smiled serenely. "No dice," she said. "Mother went back to grandmother last week. When is this thing going to cook?"

"Really, it was not his fault," objected Wes. "I wanted to check the scanner-synchronization."

"He's precious," chortled Arden in Don's ear. "He wouldn't think of letting Walt, the big bum, take the blame for anything that wasn't Walt's fault."

"That's a good line," grinned Don. "Walt's faults. After we set this thing aside as a finished project, we'll set that 'Walt's Faults' to music. Ready, Walt?"

"Right. I am now slipping the block into the cabinet. The door is closed. Have you got the preliminary synchronizing signal in tick?"

"Then since no one has any objections at this time, I assume that everything may be run off. Silence, people, we are going on the air!"

"Done!" announced Walt. "Don, crack the door so that the rest of us can laugh if it don't work."

Channing swaggered over and opened the door. He reached inside and took out the—object.

"Well, what we got at this end would positively scare the right arm off of a surrealist sculptor."

It was three miles from one end of Venus Equilateral to the other and Walt made it in six minutes from the time he stepped into the little runway car to the time he came into the north-end laboratory and looked over Channing's shoulder at the—thing—that stood on the table.

"Quite," said Don. "This is glass. It was once a three-inch cube of precision, polish, and beauty. It is now a combination of a circular stairway with round corners and a sort of accordion pleat. Hell's bells!"

"Be not discouraged," gurgled Walt. "No matter what it looks like, we did transmit matter."

"I'm ignoring your crude remark. Walt, we did accomplish something. It wasn't too good. Now let's figure out why this thing seems to have been run over with a fourth dimensional caterpillar-tread truck."

"Well, I can hazard a guess. The synchronizing circuits were not clamped perfectly. That gives the accordion-pleat effect. The starting of the trace was not made at the same place each time due to slippage. We'll have to beef up the synchronization impulse. The circular staircase effect was probably due to phase distortion."

"Could be," said Don. "That means we have to beef up the transmission band so it'll carry a higher frequency."

"Might work. Those will have to be matched closely. We're not transmitting on a line, you know. It's sheer transmission-tube stuff from here to there. Well, gang, we've had our fun. Now let's widen the transmission band and beef up the sync. Then we'll try number two."

Number two was tried the following afternoon. Again, everybody stood around and watched over Don's shoulder as he removed the cube from the cabinet.

Franks came in puffing, took the cube from Don's fingers and inspected it. "Not too bad," he said.

"Not by a jug full. The index of refraction is higher at this edge than at the other. See?" Walt held the cube before a newspaper and they squinted through the glass block.

"Second harmonic distortion, if present, would tend to thin out one side and thicken up the other side. A sine-wave transmission would result in even thickness, but if second harmonic distortion is present, the broad loops at the top create a condition where the average from zero to top is higher than the average from zero to the other peak. Follow?"

"That would indicate that the distortion was coming in at this end. If both were even, they would cancel."

"Right. Your scanning at one end is regular—at the other end it is irregular, resulting in non-homogeneity."

"That's an easy one. The wave-front isn't sharp either. Instead of clipping sharply at the end of the trace, the signal tapers off. That means higher frequency response is needed."

"We need a term. Audio for sonics; radio for electronics; video for television signals—"

"That's because it's strange. Mateo it is," said Don. "Our mateo amplifier needs higher frequency response in order to follow the square wave-front. Might put a clipper circuit in there, too."

"I think a clipper and a sharpener will do more than the higher frequency," said Farrell. He was plying a vernier caliper, and he added: "I'm certain of that second harmonic stuff now. The dimension is cockeyed on this side. Tell you what, Don. I'm going to have the index of refraction measured within an inch of its life. Then we'll check the thing and apply some high-powered math and see if we can come up with the percentage of distortion."

"Go ahead. Meanwhile, we'll apply the harmonic analyzer to this thing and see what we find. If we square up the edges and make her homogeneous, we'll be in business."

"Nope. I doubt that we could send anything very large. It might be more bother to run a huge job than the money it costs to send it by spacer. But we have a market for small stuff that is hard to handle in space because of its size."

"I see no reason why Keg Johnson wouldn't go for a hunk of it," offered Wes Farrell.

"I've mentioned it to Keg; the last time I was in Canalopsis," said Walt. "He wasn't too worried—provided he could buy a hunk."

"Interplanet is pretty progressive," mused Don. "There'll be no reason why we can't make some real handy loose change out of this. Well, let's try it again tomorrow."

It was less than a month later that a newspaper reporter caught the advance patent notice and swallowed hard. He did a double take, shook his head, and then read the names on the patent application and decided that someone was not fooling. He took leave and made the run to Venus Equilateral to interview the officials. He returned not only with a story, but with a sample glass block that he had seen run through the machine.

The news pushed one hatchet murder, a bank robbery, a football upset, and three political harangues all the way back to page seven. In terms more glowing than scientifically accurate, the matter transmitter screamed in three-inch headlines, trailed down across the page in smaller type, and was embellished with pictures, diagrams, and a description of the apparatus. The latter had been furnished by Walt Franks, and had been rewritten by the reporter because Walt's description was too dry.

The following morning Venus Equilateral had nine rush telegrams. Three were from cranks who wanted to go to Sirius and set up a restorer there to take people; four were from superstitious nuts who called Channing's attention to the fact that he was overstepping the rights given to him by his Creator; one was from a gentleman who had a number of ideas, all of which were based on the idea of getting something for nothing and none of which were legal; and the last one was a rather curt note from Terran Electric, pointing out that this device came under the realm of the power-transmission tube and its developments and that they wanted a legal discussion.

"Then to the devil with them," snapped Walt. "We'll tell 'em to go jump in the lake."

"Nope. We're going to Terra and slip them the slug. If we clip them now, they'll have nothing to go on. If we wait till they get started, they'll have a fighting chance. Besides, I think that all they want to do is to have the facts brought out. Are we or are we not under the terms of that contract?"

"We're as safe as Sol. And I know it. That contract pertained to the use of the solar beam only, plus certain other concessions pertaining to the use of the power-transmission tubes and other basic effects as utilized in communications."

"It's got to be told in a court of law," said Don. "Kingman's mind runs to legal procedure like Blackstone."

"What other? Solar beams, of course. We don't bother about running stuff around any more. We plug it in the 115-volt line, it energizes the little fellows just long enough to make them self-sustaining from Sol. All the 115-volt line does is to act as a starting circuit."

"You and Farrell had better dream up a couple of power supplies then. We can't use the solar beam on Terra."

"I know. We're a little ahead of you on that. Wes and one of the Thomas boys cooked up a beam-transducer power supply that will get its juice from any standard 115-volt, sixty-cycle line socket. We've got two of them—and they run the things easily."

"Good. I'll 'gram Terran Electric and let 'em know we're on our way for the legal tangle. You load up the Relay Girl and we'll be on our way. Stock up the usual supply of bars, blocks, gadgets, and traps. Might include a bar magnet. When we show that it is still magnetized, we'll gain a point for sure."

"If we take a magnet, we'd better take the fluxmeter to show that the magnetic field hasn't dropped."

"Right. Take anything you can think of for a good show. We can knock them dead!"

Mark Kingman put his assistant legal counsel on the witness stand. "You will state the intent of the contract signed between Terran Electric and Venus Equilateral."

"The contract holds the following intent: 'Use of the power-transmission tubes for communications purposes shall fall under the jurisdiction of Venus Equilateral. For power transmission, the tubes and associated equipment shall be under the control of Terran Electric. In the matter of the solar beam tubes, the contract is as follows: Venus Equilateral holds the control of the solar beam in space, on man-made bodies in space, and upon those natural bodies in space where Venus Equilateral requires the solar power to maintain subsidiary relay stations.'"

"Please clarify the latter," said Kingman. "Unless it is your intent to imply that Terra, Mars, and Mercury fall under the classification of 'places where Venus Equilateral requires power.'"

"Their control on natural celestial objects extends only to their own installations and requirements. Basically, aside from their own power requirements, Venus Equilateral is not authorized to sell power. In short, the contract implies that the use of the sub-etheric phenomena is divided so that Venus Equilateral may use this region for communications, while Terran Electric uses the sub-ether for power. In space, however, Venus Equilateral holds the rights to the power beam."

Frank Tinken, head legal man of Venus Equilateral, turned to Don and said: "We should have this in a technical court."

Don turned his attention from the long discussion of the contract and asked: "Why not change?"

"Judges hate people who ask for changes of court. It is bad for the requestee—and is only done when the judge's disinterest is open to question—and also when the suspicion of dislike is less dangerous than the judge himself."

"I think so. This is more than likely to turn up with differential equations, physics experts, and perhaps a demonstration of atom smashing."

Kingman finished his examination and turned away. The judge nodded sourly at Tinken. "Cross-examination?"

"The witness' statements regarding the contract are true. However, Judge Hamilton, I will attempt to show that this case is highly technical in nature and as such falls under the jurisdiction of the Technical Court. May I proceed?"

"Counsel for the plaintiff assures me that this is not truly a technical case," snapped Hamilton. "However, if you can definitely prove that the case in point hinges on purely technical matters, what you say may be instrumental in having this hearing changed. Proceed."

"Thank you." Tinken turned to the witness. "Exactly what is the point in question?"

"The point in question," said the witness, "is whether or not the matter transmitter falls under Terran Electric's contract or Venus Equilateral's contract."

"Isn't the question really a matter of whether the basic effect is technically communication or power transmission?"

"I was merely trying to bring out the technical aspect of the case," explained Tinken, "I'll rephrase the question. Is it not true that the contract between Terran Electric and Venus Equilateral is based upon a certain technology?"

"Objection!" marked Kingman. "More than half of all manufacturing contracts are based upon technical background. I quote the case of Hines versus Ingall in which the subject matter was the development of a new type of calculating machine. This case was heard in a legal court and disposed of in the same."

"No further examination," said Tinken. He sat down and turned to Don, "We're in trouble. Hamilton does not like us."

Terran Electric's lawyer called Wes Farrell to the stand. "Mr. Farrell, you are employed by Venus Equilateral?"

"It may be removed. If necessary, we can have hand-generators supplied to generate the operating power."

"Not entirely. The main components are developments of existing parts, specialized to fit the requirements."

"Certain effects noted in the power-transmission tubes plus certain effects noted in the solar beam tubes."

Kingman turned to the judge. "I intend to show that the use of these effects is stated in the contract."

"Was there any time during the development of the device any question of jurisdiction?"

"Since absolutely no attention was paid to the terms of the contract, doesn't that imply that a certain ignorance of the terms might prevail?"

"Objection!" shouted Tinken. "Counsel's question implies legal carelessness on the part of his opponent."

"How can you be aware of the ramifications of a contract that you do not read?" stormed Kingman.

"Exception noted. Counsel, will you rephrase your question so that no lack of foresight is implied?"

"Certainly," smiled Kingman. "How were you certain that you were within your rights?"

"If this plan had been open to any question, my superiors would not have permitted me—"

"That will not serve!" snapped Kingman. "You are making an implication—your testimony is biased."

"Naturally," barked Farrell. "No one but an idiot would claim to have no opinion."

"Let it pass. In other words, Dr. Farrell, you were never sure that you were within your rights?"

"I object!" exploded Tinken. "Counsel is questioning a witness whose business is not legal matters on a subject which is legal in every phase."

"Objection sustained," said Hamilton wearily. The matter was dropped, but Kingman had gained his point. The item might never appear in the records, but it was present in the judge's mind.

"Dr. Farrell," said Kingman, "since you have no legal training, precisely what has been your education and background?"

"I hold a few degrees in physics, one in mathematics, and also in physical chemistry." Farrell turned to the judge. "Judge Hamilton, may I explain my position here?"

"I have spent thirteen years studying physics and allied sciences. I believe that I stand fairly high among my fellows. Since no man may be capable in many arts, I believe that I have not been lax in not seeking degrees in law."

"No objection," said Kingman. "Dr. Farrell, in order that the process be properly outlined in the record, I am going to ask you to explain it in brief. How does your matter transmitter work?"

Farrell nodded and took time to think. Tinken whispered in Don's ear: "The stinker! He knows Hamilton hates anything more complex than a can opener!"

"Hope that our demonstration blasts them loose. That's our best bet, plus fighting for every inch."

Farrell moistened his lips and said: "Utilizing certain effects noted with earlier experimentation, we have achieved the following effects: The matter to be transmitted is placed in situ, where it is scanned by an atom-scanner. This removes the substance, atom by atom, converting the atoms to energy. This energy is then re-converted into atoms and stored in a matter bank as matter again. The energy of disintegration is utilized in reintegration at the matter bank with but small losses. Since some atoms have higher energy than others, the matter bank's composition will depend upon the scanned substance."

"The matter bank is composed of the same elements as the matter for transmission?" asked Kingman.

"No. Some elements release more energy than others. It is desirable that the energy-transfer be slightly negative. That is to say, that additional energy must be used in order to make the thing work."

"All power lines and other devices are developed for delivering energy, not receiving it. It is less disastrous to take energy from a power line than to try and drive it back in—and the energy must be dissipated somehow."

"No," said Farrell. "The substance of the matter bank is nonhomogeneous. Simultaneously, it will be whatever element is necessary to maintain the fine balance of energy—and it is in constant change."

"In passing from the disintegrator tube to the reintegrator tube, the energy impresses its characteristic signal on a sub-ether transmission system. Radio might work, except that the signal is unbelievably complex. Wired communications—"

"Wired—transfer—might work, but probably would not, due to this same high complexity in transmitted signal. At any rate, upon reception, the signal is used to influence, or modulate the energy passing from a disintegrator tube in the receiver. But this time the tube is tearing down the matter bank and restoring the object. Follow?"

"Now, Dr. Farrell, the matter transmitter does actually transmit over a power-transmission tube?"

"Hasn't it?" queried Kingman. "My worthy opponent, all questions have an answer."

"It is impossible to send communications without sending some energy. It is the intent to which the energy is put that determines the classification."

"You must send energy when you communicate with a light-blinker," grinned Farrell. "The receiving party receives the energy, but couldn't possibly read a newspaper with it. The beams at Venus Equilateral send out several million watts—and by the time they get to Luna, they require amplifications bordering on the million-times before they are usable. The intent is clear—we are not supplying power, we are sending intelligence."

"I contend," said Kingman to the judge, "that the contract states clearly that developments of this device are to be used for communications only when operated by Venus Equilateral. I further contend that the transmission of matter does not constitute a communication, but rather a transfer of energy."

"I object," said Tinken. "If this statement was objectionable to the learned counsel before, it is equally objectionable to me now."

"Previously," said Kingman suavely, "counsel was trying to influence a witness. I am merely trying to explain my point."

Hamilton cleared his throat. "Counsel is merely trying to influence the court; the same privilege will be available to his opponent at the proper time. That is why we have courts."

"I maintain that the concept of communication precludes matter transmission," stormed Kingman. "Matter transmission becomes a problem for the transportation companies and the power companies. Matter, your honor, is energy. They are transmitting energy!"

"I was trying to see Niagara Falls," she smiled. "I've heard that you could see 'em from Buffalo."

"What do you want to see Niagara Falls for, anyway? Just a lot of water falling over a cliff at two pints to the quart."

"If you recall, chum, we went to Mars, not Niagara. There wasn't two pints of water on the whole planet, let alone a thing like Niagara."

Don nodded. "At the risk of offending a lot of Buffalonians, I'm beginning to dislike the place."

"Not going too good at all. Kingman slips in a sly dig every now and then. Frankly, I am getting worried. He's got a few points that really hit close to home. If he can sell the judge on a couple more of them, we'll be under the sod."

"Not entirely. He'll have to use the beams of Venus Equilateral to operate, but he'll be collecting all the real gravy. We'll just be leasing our beams to him."

"I won't. I really hate to see Kingman get ahead of this, though." Don stretched, took another look out across the city of Buffalo, and then said: "We'd best be getting back. We'll be late.... He said ten minutes."

They went down the staircase slowly, and at the courtroom door they met Keg Johnson. The latter smiled wearily. "Not too good?"

"That isn't too good. Judges do not reverse lower courts unless a real miscarriage of justice takes place."

"Interplanet. We'll be run right out of business if this thing goes over to Kingman and that bunch."

"Plants go through with no ill effects. Microscopic life does, too. Animals we have tried died because of internal disorders—they move while being scanned, and their bodies come out looking rather ugly. An anaesthetized mouse went through all right—lived for several hours. Died because the breathing-function made a microscopic rift in the lungs, and the beating heart didn't quite meet true. We must speed up the scanning-time to a matter of microseconds and then we can send living bodies with no harm."

"That would clean out the space lines," said Keg. "I think I'll offer that bird a slice of Interplanet for an interest if he wins. We've got to have it, Don."

"Of course," said Keg wistfully. "We'll be across a barrel if you win, too. But the barrel will be less painful with you holding the handles than if Terran Electric holds them. The same offer goes for you, too."

Tinken called Don Channing to the stand as his first witness. Don explained the function of Venus Equilateral, the job of interplanetary communications, and their work along other lines of endeavor. Then Tinken said to the judge:

"I have here a glass cube, three inches on a side. This cube was transmitted from Venus Equilateral to the Lunar Station. I offer it as exhibit A. It was a test-sample, and as you see, it emerged from the test absolutely perfect."

The judge took the cube, examined it with some interest, and then set it down on the desk.

"Now," said Tinken, "if you do not object, I should like to present a demonstration of the matter transmitter. May I?"

"This isn't good," said Kingman's assistant to the lawyer. "The old goat looks interested."

"Don't worry," said Kingman. "This'll take a long time, and by the time they get done, Hamilton will be ready to throw them out. Besides, it will make a good arguing point for my final blast. And, brother, I've got a talking-point that will scream for itself."

"Look," smiled Kingman, "this is really an argument as to whether matter or intelligence is carried. Believe me, that has everything to do with it. I'm keeping one idea under the wraps until shooting-time so they won't be able to get an argument against it. We're a cinch. That's why I kept it in a legal court instead of a technical court. The Techs would award it to Channing on a technical basis, but the legal boys have got to follow my argument."

"The record of this court is still a very heavy argument. Look, they're about to start."

The racket and hubbub died, and Tinken faced the judge. "These are plainly labeled. They are matter transmitter and matter receiver. We have here a set of metal bars. They are made of copper, steel, aluminum, some complex alloys, and the brother to that glass cube you have before you. We will transmit this set of objects from here to there. Have you any suggestions?"

"Nothing that is outside of our hands," smiled Tinken. "Would you care to send something of your own? Your gavel? Inkwell? Marked coin? Anything?"

"I'd offer my glasses except for the fact that I cannot see without them," said Judge Hamilton.

"My watch. It is unique enough for me." He handed over the watch, which was quite sizable.

Tinken inspected the watch and smiled. "Very old, isn't it? A real collector's item, I dare say."

Hamilton beamed. "There are nine of them in the Solar System," he said. "And I know where the other eight are."

"O.K., we'll put it on the top. I'll have to stop it, because the movement of the balance wheel would cause a rift during transmission."

"No need to worry about that. We've sent loaded springs before. Now, people, stand back and we'll go on the air."

Don Channing himself inspected the machinery to see that nothing was wrong. He nodded at Walt Franks at the receiver, and then started the initial operations. "We are synchronizing the two machines," he said. "Absolute synchronization is necessary. Ready, Walt?"

Channing pushed a button. There was a minute, whirring hum, a crackle of ozone, very faint, and an almost-imperceptible wave of heat from both machines. "Now," said Walt Franks, "we'll see."

His face fell. It turned rosy. He opened his mouth to speak, but nothing but choking sounds came forth. He spluttered, took a deep breath, and then shook his head in slow negation. Slowly, like a boy coming in for a whipping, Walt took out the judge's watch. He handed it to Don.

Don, knowing from Walt's expression that something was very, very wrong, took the watch gingerly, but quickly. He hated to look and yet was burning with worried curiosity at the same time.

In all three dimensions the watch had lost its shape. It was no longer a lenticular object, but had a very faint sine wave in its structure. The round case was distorted in this wave, and the face went through the same long swell and ebb as the case. The hands maintained their distance from this wavy face by conforming to the sine-wave contour of the watch. And Channing knew without opening the watch that the insides were all on the sine-wave principle, too. The case wouldn't have opened, Don knew, because it was a screw-on case, and the threads were rippling up and down along with the case and cover. The knurled stem wouldn't have turned, and as Channing shook the watch gently, it gave forth with one—and only one—tick as the slack in the distorted balance wheel went out.

"I can only think of one answer," offered Channing in a low voice. "We made the power supplies out of power and voltage transducers and filtered the output for sixty cycles. Buffalo is still using twenty-five-cycle current. Since the reactances of both capacity and inductance vary according to the—"

"Enough of this!" roared Hamilton. "I—No, I may not say it. I am on the bench and what I am thinking would bring impeachment. Proceed, Attorney Kingman."

Kingman took the cue, and before anyone realized that it was still Tinken's floor, he opened.

"Dr. Channing, you can send a gallon of gasoline through this, ah, so-called matter transmitter?"

"Then, your honor, it is my contention that no matter what the means or the intent, this instrument utilizes the sub-etheric effects to transmit energy! It is seldom possible to transmit power over the same carriers that carry communications—only very specialized cases prevail, and they are converted to the job. But this thing is universal. Perhaps it does transmit intelligence. It will and can be used to transmit energy! Matter, your honor, is energy! That, even the learned opponent will admit. We have our own means of transmitting power—this is another—and no matter what is intended, power and energy will be transmitted over its instruments.

"Since this machine transmits energy, I ask that you rule that it fall under that classification. I rest my case."

Hamilton nodded glumly. Then he fixed Tinken with an ice-cold stare. "Have you anything to offer that may possibly be of any interest to me?"

"I shall deliver my ruling in the morning. I am overwrought and must rest. Adjourned until tomorrow morning."

The only sounds in the room were the tinkle of glassware and the occasional moan of utter self-dislike. Channing sat with his glass in his hand and made faces as he lifted it. Franks matched his mood. Both of them were of the type that drinks only when feeling good because it makes them feel better. When they drank while feeling low, it made them feel lower, and at the present time they were about as far down as they could get. They knew it; they took the liquor more as a local anaesthetic than anything else. Arden, whose disappointment was not quite as personal as theirs, was not following them drink for drink, but she knew how they felt and was busying herself with glass, ice, and bottle as they needed it.

It was hours since the final letdown in the court. They knew that they could appeal the case, and probably after a hard fight they would win. It might be a year or so before they did, and in the meantime they would lose the initial control over the matter transmitter. They both felt that having the initial introduction in their hands would mean less headache than having Terran Electric exploit the thing to the bitter end as quickly as possible.

The fact of sunrise—something they never saw on Venus Equilateral—did not interest them one bit. It grew light outside, and as the first glimmerings of sunrise came, a knock on their door came also.

"Look, fellows, I'm sorry about that fool mistake. I've been working on the judge's ticker. I've fixed it."

Farrell dangled the judge's watch before them. It was perfect. It ticked, it ran, and though they couldn't possibly have seen the hands from a distance of more than nine inches, it was keeping perfect time.

Don shook his head, moaned at the result of the shaking, put both hands on his head to hold it down, and looked again. "How'ja do it?"

"Made a recording of the transmitted signal. Fixed the power supply filters first. Then took the recording—"

"On a disk like the alloy-tuners in the communications beams. Worked fine. Anyway, I recorded the signal, and then started to buck out the ripple by adding some out-of-phase hum to cancel the ripple."

"Yes. Had a bit of trouble making the ripple match." Farrell pulled several watches from his pocket. "This one added ripple. It's quite cockeyed. This one had cross-ripple and it's really a mess. It sort of looks like you feel, Walt. I've got 'em with double ripples, triple ripples, phase distortion, over-correction, and one that reminds me of a pancake run through a frilling machine."

Channing looked at the collection of scrambled watches and shuddered, "Take 'em away—brrrrr."

"You're a taxi," giggled Arden. "O.K., fellows. Can do." She went to the phone and started to call.

Farrell looked uncomprehendingly at Walt and then at Don, and shook his head. "Mind telling me?" he pleaded.

"Let them alone," she said. "Something probably pleases them highly. We'll find out later—yes? Operator? Will you call a cab for room 719? Thanks."

Attorney Tinken faced Judge Hamilton with a slight smile. "Prior to your ruling, I wish to present you with your watch. Also I ask permission to sum up my case—an act which I was unprepared to do last evening."

"You may state your case—but it will make little difference in my ruling unless you can offer better evidence than your opponent."

"Thank you," said Tinken. He made a show of winding the watch, and he set it accurately to the court clock on the wall. "Your honor, a telegram is a message. It requires energy for transmission. A letter also requires energy for carrying and delivery. A spacegram requires the expenditure of great energy to get the message across. The case in hand is this: If the energy is expended in maintaining the contact, then communications are involved. But when the energy is expected to be used on the other side—and the energies transmitted are far above and beyond those necessary for mere maintenance of contact, it may then be construed that not the contact but the transmittal of energy is desired, and power transmission is in force."

"The matter of sending flowers by telegram is not a matter of taking a bouquet to the office and having the items sent by electricity to Northern Landing. A message is sent—an order to ship or deliver. It makes no difference whether the order be given in person or sent by spacegram. It is a communication that counts. In this device, a communication is sent which directs the device to produce a replica of the transmitted object. Ergo it must fall under the realm of communications. I will now demonstrate this effect, and also one other effect which is similar to telegraphic communications."

Tinken ignored Hamilton's outstretched hand, and put the watch in the cabinet. Hamilton roared, but Tinken put up a hand to stop him, "I assure you that this will cause no ill effects. We have repaired the damage."

"For every minute of delay between now and the moment I receive my watch, I shall fine you one hundred dollars for contempt of court," stormed Hamilton.

Click! went the receiver, and from a slide, Channing removed the judge's watch. With a flourish he started it, and handed it to the judge, who glared.

"That last buzz or burp was a signal that we have reached the end of our matter bank, your honor. Our credit, for example, has run out. However, Dr. Channing is about to make a substantial deposit with the manufacturer, and we will resume operations later. I ask you—

"—machine before I have you all held for disrespect, perjury, contempt of court and grand larceny!" yelled the judge.

Channing stopped the machine and started to hand out the carbon-copy watches to the audience, who received them with much glee. Kingman came to life at this point. He rose from his chair and started to object, but he was stopped by Tinken who leaned over and whispered:

"My worthy and no doubt learned opponent, I'd advise you to keep your magnificent oratory buttoned tight in those flapping front teeth of yours. If we all get into that gadget—how would you like to fight ten or twelve of us?"

Interlude:

Don Channing turned from the court and made his way through the room to the hallway. In his hand he bore one of the judge's watch-replicas. In his mind he had the world by the tail.

He was going to leave the court, make his way to Venus Equilateral and launch a new era.

PANDORA'S MILLIONS

Keg Johnson was the executive type. He was the chief executive of Interplanet Transport, a position of no mean height. Keg had become the chief executive by sheer guts, excellent judgment, and the ability to gamble and win.

Like any high executive in a culture based on a technical background, Keg was well aware of science. He was no master of the scientific method nor of laboratory technique. He was able to understand most of the long-haired concepts if they were presented in words of less than nine syllables, and he was more than anxious to make use of any scientific discovery that came from the laboratory. He knew that the laboratory paid off in the long run.

Keg Johnson was strictly a good business man. He played a good game and usually won because he could size up any situation at a glance and prepare his next move while his opponent was finishing his preparatory speech.

So when Keg Johnson met Don Channing in the hallway of the courtroom in Buffalo, he was dangling an exact replica of the judge's watch—a timepiece no longer a rare collector's item.

Keg's eyes followed the Terran Electric's lawyer, Mark Kingman, as he left the courtroom.

"He's been trying to put you out of business for a couple of years, Don, without any success. But you just put your own self out of comish. Venus Equilateral is done for, Channing."

"Meaning?" asked Don, lowering his eyebrows. "Seems to me that you're the one that should worry. As I said, we'll give you your opportunity to buy in."

"Interplanet Transport is finished," agreed Johnson. He did not seem overly worried about the prospect of tossing a triplanetary corporation into the furnace. "So is Venus Equilateral."

"Do go on," snapped Don. "It seems to me that we've just begun. We can take over the job of shipping on the beams. The matter-transmitter will take anything but life, so far. Pick it up here, shove it down the communications beams and get it over there. Just like that."

"That's wonderful," said Keg in a scathing voice. "But who and why will ship what?"

"Once they get recordings of Palanortis Whitewood logs on Mars, will we ship? Once they get recordings of the Martian Lagel to Northern Landing, who will take the time to make the run by ship?"

"The bulk of your business, my brilliant friend, comes not from lovesick swains calling up their gal friends across a hundred million miles of space. It comes from men sending orders to ship thirty thousand tons of Venusian Arachnia-web to Terra, and to ship ten thousand fliers to Southern Point, Venus, and to send fifty thousand cylinders of acetylene to the Solar Observatory on Mercury, and so forth. Follow me?"

"I think so," said Channing slowly. "There'll still be need for communications, though."

"You've got a terrific laboratory job ahead of you, Don. It is one that must be done—and quick! You owe it to the world, and to yourself, and to your children. You've brought forth the possibility of a system of plenty, Don, and left it without one very necessary item.

"Furthermore, chum, what are you going to barter with? A ton of pure gold is the same value as a ton of pure silver. That is, aside from their relative technical values. A ton of pure radium won't bother us at all, and if we want Uranium 235, we make it by the ton also. Oh, brother, you've really screwed the works this time."

"You and your crew start looking for something that is absolutely un-reproducible. It should be a light, metalloid substance of readily identifiable nature, and it should be ductile and workable. We need a coin-metal, Channing, that cannot be counterfeited!"

"Yum. That's one for the book. Meanwhile, we'll retrench on Venus Equilateral and get set for a long, long drought."

"Check. I'm about to do likewise with Interplanet Transport. You don't know anybody who'd like to buy the major holdings in a spaceline, do you? It's on the market, cheap. In fine condition, too, in spite of the depredations of Hellion Murdoch."

Johnson smiled. "No dice. I'm looking for a specialized business, Don. One that will pay off in a world where there is no money!"

"Those are items that your devil-gadget won't duplicate, Channing. Barter and exchange on the basis of a washed car's worth of dug postholes."

Linna Johnson looked up with some annoyance as Keg entered her room. She was a tall woman, lissome in spite of her fifty years, but the artificial stamp of the "woman-of-fashion" spoke louder than her natural charm.

"Give up my jewelry?" scoffed Linna. "What sort of a tramp deal have you got into this time, Keg?"

"So—you've sold your spaceline. That should have brought you in a pretty penny. What do you need more for?"

"Fabriville. A fairly large manufacturing village south of Canalopsis, here. They have a complete village, assembly plant, stores, and all that's needed to be self-sufficient if you permit a thorough income and out-go of fabricated articles."

"Well," said Keg dourly, "there are a lot of things you have never heard of nor taken the interest to find out, Linna. Better shell out the baubles. They won't be worth an exhausted cathode inside of a year."

"The economic structure of the system is about to be shot to pieces in a box. Nothing will be worth anything in money. A diamond as big as your fist will be just so much carbon crystal. I want to butter us up, Linna, before the crash. That's the way to do it."

"Don Channing and Walt Franks have just developed a gadget that will transmit articles any distance. That shoots Interplanet. The articles—or the signal impulses from them—can be recorded, and the recording can be used to duplicate, exactly, the same thing as many times as you want it."

"You idiot," scorned Linna, "why not just get one and duplicate your present money?"

"Merely because an operator as large as myself cannot palm off two hundred $1,000 bills with the serial number AG334557990HHL-6. Counterfeiting will become a simple art soon enough, Linna, but until it is accepted, I'm not going to break any laws. I can't if I'm going to shove ahead."

"Not going to. They'll pay for themselves. We'll send 'em back and keep duplicates which we'll make."

"Look, Linna. Shell out. I've got to hit the market this afternoon if I'm going to grab Fabriville."

"Seems to me that getting that place is slightly foolish," objected Linna. "If nothing will have any value, why bother?"

"If the junk is that important," exploded Keg, "I'll promise to replace them all with interest as soon as we get running."

"Yes," said Keg wearily. "It's a promise. I've got to make an option payment immediately. From then on in, the place will be mine."

"I can't miss. All I want to do is get out what I need before the bottom falls out. Inflation of the worst kind will set in, and the wheels will stop dead—except at Fabriville. That's where I enter the picture."

"Good," said Linna in a bored voice. "As long as I am assured of my jewelry, I don't care how you play the market. Run along, Keg. I've got a dinner engagement. May I have just a few, though? I'll feel naked without at least a ring."

"Take what you need," said Keg, and was immediately appalled at the necessities of life.

An hour later, Keg Johnson was making some quiet trading and slowly but surely gaining control over the manufacturing village of Fabriville. The market was steady and strong. The traders worked noisily and eagerly, tossing millions back and forth with the flick of a finger. It was a normal scene, this work of theirs, and when it was done, they would take their usual way home to a quiet evening beside a roaring fireplace.

But this was surface quiet. Deep down below there was a miniscule vortex that churned and throbbed, and other equally minute forces fought the vortex—and strove in a battle that was lost before it began.

Terran Electric bought a full page advertisement in every paper. A five-minute commercial assailed the ears from every radio that listened to the Interplanetary Network. A full column emerged from the morning news-facsimile machines. Terran Electric, it said, was announcing the most modern line of household electrical appliances. Everything from deep-freezers to super-cookers. Everything from cigarette lighters to doorbell chimes.

But on page seventeen, hidden among the financial and labor-situation news, was a tiny, three-line squib that told the story to those who knew the truth. Terran Electric had just released sixty percent of their production-line labor.

Don Channing caught the squib, and headed for Evanston less than fifteen minutes after reading it.

Unannounced, Don Channing entered Kingman's office and perched himself on the end of Kingman's desk. His bright blue eyes met Kingman's lowering brown eyes in a challenge.

"You utter fool," snapped Don. He lit a cigarette and blew a cloud of smoke at Kingman, making the other cough.

"Plenty. Until the crash comes, I'm laying in a stock of stuff for my personal use."

"Lovely set-up," grunted Channing. "Have you started duplicating the duplicating machines yet?"

"What shall I do, Dr. Channing?" asked Kingman sourly. The title grated on Don's ears, and Kingman knew it.

"And what are you going to do about it?" asked Kingman. "Take me to court, Channing. Go ahead. Get some litigation started."

"Oh, sure. And you'll tie the thing up for seventy years. And all the time the plant here will be duplicating the whole solar system into the worst mess it ever got itself into. Better stop until we can get something sensible figured out to take care of the conversion."

"That in itself will take ten years," said Kingman. "Meanwhile, money is still of value because the thing is not widespread. People will buy and sell, and I'm going to buy up enough to keep me and mine in the running until things settle down. You have no idea how much stuff is needed to keep a man running ten years, Channing. Especially when you try to store it all away at once. Oh, sure. Recordings. I know. I'm making them. Also making recordings of everything that I can think of that I might like. But getting originals takes money at the present time, and I'm going to ride the inflation market right up to the peak by being one step ahead all the way."

"When butter is ten dollars a pound, Channing, I'll be producing and selling its equivalent at fifteen."

"You're licked. You'll be no better off than any of us in the long run. What happens when everyone has duplicators in their own homes and are having their Sunday dinner coming out of the gadget complete; hot, delicious, and costlessly complete from the salt-cellar to the butter square? What price butter?"

"That'll happen," admitted Kingman. "But by the time it does, I'll be able to weather the storm."

"This is going to be a nice, level civilization by the time we get through with it," said Kingman. "There'll be no more shopping for food. No more working thirty hours a week for your pay so that you can buy the niceties of life. With your household duplicator, you can make everything you need for life, Channing. The Terran Electric label on your duplicator is the label of the New Way of Living."

Channing snorted and crushed out his cigarette with a vicious gesture. "You've been reading your own advertising," he gritted. "Kingman, what do you hope to gain?"

Kingman leaned back in his chair and put both of his feet on the desk. "I don't mind telling you," he said gloatingly. "Venus Equilateral is going to have the name of having invented and developed the matter transmitter and matter duplicator. That's fine. It will carry quite an honor, that reputation, up to the time that the big crash comes, when people realize they're being trapped. Terran Electric, selling duplicators for home use at a song, will emerge as the savior of mankind. All I'm going to gain out of this is security for Mark Kingman and a big black eye for Venus Equilateral."

Channing swore. He stood up. "You fool," he snapped, "you blind, bigoted fool. A little co-operation on your part would save a lot of trouble, but you prefer to let a petty quarrel ruin the entire economic system immediately. We could work this out sensibly, Kingman. Will you help?"

"I don't need a production line full of people, Channing, to sit around and watch a duplicator turn out vacuum cleaners, complete in their packing cartons."

Channing took Kingman's under ankle where they were crossed on the edge of the desk. He lifted, and the pudgy attorney went over backwards with a roaring crash, hitting his head on the carpet and spilling over backwards out of the chair onto the floor behind his desk. He arose with a roar of hate, but the door slammed behind Channing before Kingman could become coherent.

Channing returned to Venus Equilateral immediately, a trip that took four days. In touch with events by driver beam, Don heard the news-advertising agencies announcing the Terran Electric Duplicator of a size suitable for a medium home, complete with a recording attachment and a supply of disks. Channing gritted his teeth and stepped up the drive of the Relay Girl another notch. His first query upon reaching the Station was to Wes Farrell.

"Nothing yet, Don," answered Wes. "We've been running some very interesting experiments, though."

Channing was interested in nothing but the non-duplicatable material, but he nodded. Wes Farrell's sideline experiments often paid off more than the main line of research.

"By inserting a filter circuit in the transmission beam, we can filter out other responses," said Wes. "Meaning that we can take a cube of regular iron, for instance, and run it through. The integrated iron in the receiver is pure iron, the purity of which is dependent upon the band-pass of the filter. Using alloy selectivity disks for filters in the circuits, we can make iron that is 99.99997% pure."

"Might be useful for metallurgical work, and so forth," mused Don. "Nine-nines iron is valuable and almost impossible—and it takes a gadget that destroys value to make it. Nice paradox, that."

"Another thing," said Wes. "We re-transmit the pure iron and heterodyne the impulses into other elements. We can start with iron and end up with any of the other elements, merely by introducing the proper heterodyning impulse."

"I've got several elements that start off where the Periodic Chart ends. The boys in the chemistry lab are investigating the properties of Venium, Channium, Frankine, Ardenium, and Farrelline right now."

Farrell was interrupted by the insistent call on the station intercom for Don Channing. Don went to his office to find the Terran beam awaiting his presence. He lifted the phone and identified himself.

"Just a minute," said Don. "I might as well know what I'm being suspected of. Whom have I murdered?"

"Yes. The trouble is that it isn't phony. You can always detect spurious coins and counterfeit bills by some means or another. We have bits of nita-fluorescin in the bills that is printed into the paper in a pattern which is symbolically keyed to the issue—date, the serial number, and the identifying marks on the face of the bill. It takes a bit of doing to duplicate the whole shooting-match, but we've been getting stuff that we know is phony—but, Channing, I have the original and the duplicate here on my desk and I can't tell which is which!"

"I have a hundred dollar bill here—two of them in fact. They are absolutely alike. They are both bona fide as far as I or my men can tell from complete analysis, right down to the bits of stuff that get ground into a bill from much handling. I have coinage the same way. Isn't there something that can be done?"

"We are trying to find a substance that cannot be duplicated," explained Channing. "Given time, we will. Until then, I'm helpless."

"I don't know. I've been hoping that we could control the situation until something sensible could be worked out. It slipped out of hand. I'd suggest that you'd stop operations because of the absolute impossibility of keeping your thumb on things. I'd forget the counterfeiting angle entirely and start building up a force to guard against riots, mob rule and minor, intercommunity warfare."

"I think you're right," said Hughes, and Channing knew that the head of the Interplanetary Criminal Office was nodding his head.

Channing hung up the telephone and toyed with three copies of the judge's watch that were keeping identical time. He shook his head and wondered how it was all going to end.

Conversion from production line to duplicator came all over the Solar System in about ten days. Terran Electric's own staff fabricated a duplicator capable of handling an object the size of a locomotive, and plant-sized duplicators were formed, one after the other on flat cars that rolled from the maw of the huge machine. For payment, Terran Electric accepted blocks of stock in the purchasing companies, and the wealth and holdings of Terran Electric mounted high and began to look like the major company that would ultimately control all merchandising and manufacture in the System.

And thirty days after the conversion came, the wheels ground to a stop. Industry was finished. Work had ceased. Plants lay idle, nothing to do—and no one to do it for them.

Keg Johnson looked up as Linna entered. There was a worried look on her face that caused Keg to inquire immediately as to its cause.

Keg picked it up. "Looks all right to me," he said. "Like the real article. What's wrong with it?"

"Nothing that I can tell," grumbled his wife. "Excepting that my maid has one like it. Exactly."

"But what's the world coming to? If my maid can afford a diamond bracelet like this, she won't be working for me very long."

"At that, you're probably right. I'd treat her with the most delicate of care," said Keg.

"Look, Linna. You're not up-to-date. I can predict people sleeping in gold beds and eating from solid platinum dishes before the hysteria dies out. The economic set-up has gone to pot, Linna, and we're trying to work it out."

"It isn't a matter of what it's coming to, it's a matter of where it has gone. My technicians tell me metals will be rated in value as per their atomic number. Uranium is more expensive than lithium because the transmutation-factor is higher. It takes a little more power and more matter from the matter bank in the instrument to make uranium than lithium, ergo uranium will cost more."

"Then if this diamond bracelet is worthless, can't we get some uranium jewelry?"

"Sure—if you want it. But remember it is radioactive and therefore not to be worn too close to the skin. It isn't as bad as radium, for instance, but it is bad enough. Besides, Linna, the matter of uranium's value over lithium is a matter of a few tenths of a per cent."

"In Terran dollars about forty-seven million, six hundred fifty-two thousand, three hundred and eight."

"Linna, dollars are worthless, these days. Monetary holdings are worthless. Stocks and bonds are likewise useless. Interplanet isn't shipping a thing. Venus Equilateral is handling sentimental messages only, and they'd be running at a loss if it weren't for the fact that they're out in space where power comes from Sol."

"But why? Keg, you know I've never questioned your ability. You have always enjoyed the run of big business. Whenever I've needed or wanted anything, it has been available. I write checks and never question the balance. But this has me stopped. What has happened, specifically?"

"It will. That's why we'll have people sleeping in solid gold beds, and enjoying silver plumbing. Platinum will have no more value than a slab of lead of the same weight. You see, Linna, when they can duplicate anything—in quantity—it includes money, stocks, bonds, and jewelry as well as radio receivers, automobiles, refrigerators, and table lamps. No one will take one dime's worth of money because it is valueless. Why should I sell my fountain pen for fifty dollars when I can make fifty dollars by pushing a button? Or the other guy can make a fountain pen by pushing a button? Follow?"

"Well, I've heard it said that someone will like to do everything—someone will find pleasure in digging latrines if you look for him long enough."

"Not good enough. Barney Carroll likes to tinker with radio. He's good, too. But it is a hobby, and Barney's tinkering will not produce anything like a commercial receiver. Oh, it'll work, and as good as any set, but no one would have the thing in the living room because it has no artistic appeal. But say it did. Fine. Then what about the automobile boys? Has anyone ever tried to make his own automobile? Can you see yourself trusting a homemade flier? On the other hand, why should an aeronautical engineer exist? Study is difficult, and study alone is not sufficient. It takes years of practical experience to make a good aeronautical engineer. If your man can push buttons for his living, why shouldn't he relax?"

"Linna, I bought this place so that we could work it out. There is one thing that cannot be duplicated."

"You can't machine-clean the house. You can't machine-write books, music, or moving pictures. You can't machine-maintain machinery. You can't machine-doctor a burst appendix. And so forth. You can duplicate the antiques until they have no value. Rembrandt is going to be a household word. The day of the antique is gone, Linna, and the eventual trend will be toward the unique. Mark my words, there will one day be unique shops that deal in nothing but items which they can certify as never having been duplicated."

"But if service is of value," said Linna doubtfully, "how am I going to get along?"

"Look, Linna. You're my wife. As my wife, you've been spoiled. That's my fault. I liked to spoil you. In the early days I couldn't spoil you because we were in no financial position to do any spoiling, but now you've become a parasite, Linna. You and your dinners and your jewels and your cars and your sleek, vacuum-brained friends. Patron of the arts! Nuts. Bum poetry, slapdash canvases, weird discordant music. No, it's not entirely your fault. I've sponsored it because I thought it gave you pleasure.

"But we're all on the same level now," he continued reflectively. "No one is any better than his brains. I've been graced. It has been my very lucky lot to be in a position where I can sway men to my will. Fabriville is mine—and yet it belongs to every man in it equally. I can't get along without them, and they can't get along without Fabriville."

"I don't know. It is tough. We have three physicians and two surgeons and a couple of high-powered diagnosticians. The question is this: How much time should Mrs. Jones desire of Dr. Hansen? She has a bit of rheumatism. Larkin, on the other hand, has a bad case of gallstones. Obviously, these two must not enjoy equal call upon Dr. Hansen. Furthermore, these two must not be expected to pay the same figure."

"In service, Linna. The board of strategy sits for several hours each day deciding upon things like this—and it is not simple. How many hours of gardening is worth removing gallstones? And what happens to Dr. Hansen when he has seventeen gardeners, four butlers, nine chauffeurs, fifteen cooks, and twelve of each of the rest?"

"But how do we tackle it? Until someone gets a medium of exchange, we're forced to go on the barter-and-trade basis. Fabriville will toss out anyone who isn't paying his way by working. In return, he has free call upon the market, the manufacturing center, and the professionals. Thank God that hoarding is silly in a realm of plenty."

"So what?" said Keg flatly. "I'm working. I get no more for this than Joe Doakes, who is out there painting the flagpole."

"Sure, I like to do this. But Joe Doakes always wanted to run up a flagpole on a bosun's chair and paint it. We're exactly even. At least in Fabriville, we aren't doing without anything. Eventually the rest of the worlds will fall in line and there will be enough of stuff for everyone, but until that time arrives, we'll be seeing trouble."

"There'll be riots and small-town wars. I only hope we can get our fence up before they decide to call on us."

"You've sort of created an oasis here," said Linna. "But how long will it last?"

"Until Channing and Franks come up with some substance that can not be run through their own duplicator. I hope it will not be too long."

Out in the Trojan Position ahead of Venus, Venus Equilateral moved in its quiet way. Like Fabriville, Venus Equilateral was self-sufficient. Furthermore, Don Channing had declared a closed corporation, and the three thousand inhabitants of the relay station were all in accord.

Business was running low. Yet the salaries went on, even increased, while prices went dropping to ridiculously low levels.

With a closed system such as Venus Equilateral, such an artificial economy was possible by mere basic control. The crime angle was nil on Venus Equilateral. With three thousand people living in a cylinder of steel three miles long and a mile in diameter, crime and general nastiness were eradicated by the simple means of making it too hard to conduct anything illegal. The citizens of Venus Equilateral were patriotic to the nth degree.

So the situation was less strained than in Fabriville. Though work moved slowly, there was still more than plenty for everyone, and the people were satisfied.

They were an unsuspicious lot and so they did not think it off-color when a small spacecraft of the plutocrat class came circling up to the South End landing stage. The craft landed, and a tall, broad-shouldered man emerged and asked for Channing. He was escorted along a mile of car-way in the outer skin of the station and then whipped up toward the center of the station for five hundred feet. He was led along the broad corridor and shown the main office of the Director of Communications.

Don Channing's secretary opened the door and said: "A Mr. Laurus Towle to see you, Dr. Channing."

Towle entered behind the girl, who introduced him to Don and to Walt Franks. Then she left.

And as the door closed, Towle whipped out a revolver and pointed it at Channing. Walt slid forward off his chair and brought the chair around over his head with a single, flowing motion. Towle ducked the thrown chair, faded backwards, and fired at Don.

The shot pinged against the steel wall, flaking off some of the plastic covering. Don dropped to the floor, and came up with his wastepaper basket, which he hurled at Towle. Towle ducked, fended it aside with his left hand, and tried to level the gun again. Walt Franks reached into an open file drawer and grabbed a large handful of papers, which he threw at Towle. They fluttered and filled the air for a moment, which distracted Towle long enough for Channing to leap over the desk.

Don and Walt closed on Towle in a high-low tackle, Don jumping at Towle's head and shoulders from the desk top, while Franks hit Towle sidewise at the thigh-level in a crashing tackle. They rolled over and over and Towle lost his revolver.

The papers were still fluttering to the floor when they came to rest with Towle neatly squelched beneath Channing and Franks. Towle tried to heave them off. Don almost knocked Towle's jaw loose with a stinging backhand slap. "Don't try," snarled Don, "you're had—right now!"

"Try it again and we'll ruin you some more," promised Don. "I have an aversion to being shot at."

"Now look," said Don in a voice that gave no idea of softness, "you're licked from here on in. This weapon of yours is now ours, and we'll hang it in the museum with other mementoes of our having been shot at. Luckily, this makes the first time that it has been close. Say—you aren't an old crony of Hellion Murdoch?"

"Good. Now, as I was saying, we've disarmed you—Walt, take a prowl of his person and see if he has any more lethal instruments concealed thereupon—and we're inclined to get up off the floor and resume our roles as gentlemen. Besides, I want to know what you had in mind besides assassination."

They lifted the man from his supine position and planted him roughly in an overstuffed chair. Don and Walt sat on one edge of the desk, ready to move in with the first wrong move. Don snapped the communicator and spoke to the girl outside. "Mr. Towle had an accident with an exploding cigar, Lorraine. No one need enter."

Towle bristled at the laugh. "It's no laughing matter, Channing. For most of my life I've been saving to retire. In the turn of a wrist, you have made all my savings useless."

"Look, Towle, you worked hard for them, I do not doubt. But you've got just what you wanted anyway. You have a duplicator?"

"Tough," said Channing. "I suppose you're mad because the foolish grasshopper is now enjoying the same benefits as the ambitious ant. That's not right, I suppose. But on the other hand, why should any man be a slave to toil?"

"Baloney. Next you'll be telling me that men were better off with a ten-hour day and a six-day week."

"Nor did they have as much fun," said Channing. "Nor were there as many developments made in the fields of science and industry. Men slaved and worked and lived and died without ever seeing the pleasure of the country sky. The radio would have been useless without leisure to enjoy its offerings. And who will say that radio is a useless science?"

"But it is not right that I should have slaved to acquire a retirement fortune only to have it wiped out."

"Look, Towle, the whole system is undergoing a radical change in the economic structure. By the same token, Venus Equilateral is a ruined concern. We've dropped from ten million paid messages per day to a mere handful. Those we send through because we are bound by agreement to maintain service at all costs. We aren't making expenses, if you feel like hollering about money. Would you like a few million?" asked Channing suddenly.

"And you used your duplicator to run up your fortune first thing, didn't you?" asked Channing scathingly.

"And you're sore because everyone else did the same thing. Towle, you're a dope. You've been feeling very virtuous about working like a slave for your fortune, which would probably keep you in cakes and lodging for the rest of your life. You've been promising starvation and pauperism to anyone who bought anything that seemed the slightest bit frivolous to you. Now that the axe has slipped, you're mad because the guy who liked to ramble amid the roses is not going to starve to death as per schedule. What's wrong with you? You're not going hungry. You'll be better off than before. As soon as we get this mess ironed out, you'll be able to enjoy life as before. Your savings are safe. As soon as we get a medium of exchange that works, you'll be credited—the government took care of that as soon as the bottom fell out of the monetary system. Call 'em dollars, credits, or whathaveyous, they'll all be prorated and you'll then enjoy your fortune—though it won't be as much fun because no man is going to have to slave again. You're a crazy man, Towle, and as such I'm sending you back to Terra under guard. We'll let the psychologists work over you. Maybe they can make you behave."

They stood Towle up, rang and waited for a guard, and then saw the man off under the guard's eye.

And Don Channing said to Walt Franks: "Until we find a medium of exchange, there'll be the devil to pay and no pitch hot."

Walt nodded. "I'm glad we're out here with our little colony instead of where lots and lots of people can come storming at the gates demanding that we do something. Hope Keg Johnson is holding his own at Fabriville."

It was a growling mob that tramped across the desert toward Fabriville. A growling, quarreling mob, that fought in its own ranks and stole from its own men. A hungry, cold, and frightened mob that followed a blustering man named Norton, who had promised them peace and plenty if they did his bidding. His law did not include sharing among themselves, and so men fought and stole food and clothing and women.

Had the mob been anything but a shaggy, travel-weary band, Fabriville might have been wiped from the face of Mars.

It swept forward without form and like an ocean wave, it laved against the cyclone fencing that surrounded that part of Fabriville and was repulsed. A determined, well-fed band would have crushed the fencing, but this was a dispirited mob that would have sold its leader for a square meal and would have worked for the promise of a second meal in a row.

Keg Johnson came to the edge of Fabriville in a medium-sized tank that could withstand the entire mob to the last man. He ran the tank out of the gate and right to the edge of the mob, who shrank back to permit the thundering monster to pass. He stopped the tank and stood up in the top turret and spoke.

Johnson nodded. "I can see that," he said dryly. "How did you collect this gang?"

"Most of this outfit were caught in the crash. Their incomes did not permit them to buy duplicators, and their friends were too busy running up their money to hand any out."

"And in the smaller cities, the attendants at the power stations left. There are a horde of dead towns on Mars today. That is why we have come here. We know that Fabriville is self-sufficient. We intend to join you."

"Want to try it?" asked Keg, patting the twin 105-mm. short rifles that looked out over the mob.

"I'll try appealing to your better nature," said Norton softly. "Shall we starve and shiver while Fabriville eats and is warm?"

"Then listen. We need a more sturdy fence around Fabriville. We have the material—who hasn't?—but we have not the manpower. Get your mob to run up this fence, Norton, and I'll see that you are paid by giving each and every man a household-size duplicator complete with a set of household recordings. Is that a deal?"

Norton smiled wryly. "And what good is a duplicator with no place to plug it in? The power stations are down all over Mars."

"In building this fence," said Keg, "you are working out the value of the duplicators. Now look, Norton, in order to make this thing tick, I want to know whether you and your motley crew are honest. There are enough of you to man every vacant power station on Mars. If you, as leader of this gang, will see to it that the stations are manned and running every minute of the day, I'll see that you are given the benefits of Fabriville's more massive duplicators. That means fliers, and equipment of that size, Norton. Are you game?"

"No more than you. I can eat only so much. I can wear only so much. I can use only so much. But it is my pleasure to run things, and I like to do it. Therefore I shall run things until people decide that they want another man to run things. Until that date, Norton, you'll answer to me."

"You don't have to. No one is going to kill you for spitting in my eye. But if you have sense, you'll see that working my way will ultimately bring you more reward than going on as an unruly mob. Replace me if you can, Norton, but remember that it cannot be done by force. I have too many real friends out across the face of Mars who won't let me be shot to pieces. I've done them the same service I'm doing you. Take it or leave it."

"We have thirteen thousand people in Fabriville. To take on another ten thousand would complicate our work-system to the breaking point. We're running pretty close to chaos as it is, and we couldn't take more. If you'll set up the power stations and start small communities at these points, you'll all be better off."

"Nothing. You'll be fed and clothed and housed. That's all that any of us are. Men out there are all the same, Norton. No one has a dime. They're all bankrupt. There isn't one of them that can buy a thing—even if the stores were open. But not one of them is starving, and not one of them is going unclothed, and not one of them is going without the luxuries of life, except for those communities of which you speak. Take life to them, Norton, and you'll be the ultimate gainer."

"The duplicator will run on direct current," said Keg. "They just have a set of fully charged batteries recorded. They have a set in spare. When battery one runs down, battery two takes its place, and the first thing run off is a spare battery number three, and so on. The exhausted batteries are dumped into the matter bank and re-converted. But it is not a real luxury, running on batteries. They need the high power that your stations will deliver. They need the telephone and the radio which your men can maintain. Go and seek the officials of the various companies, and tell them what you want to do. Work at it, Norton. There will be a lot of men in your gang that would rather do something else. Eventually you will be able to release them to do the jobs you are best fitted for. Until we get a medium of exchange, it is a job proposition. I'll add this inducement: 'The medical service of Fabriville is yours—providing that you and your men will work with us.'"

Norton thought for a moment. "Done," he said shortly. "Can you give us warmth and food until we take care of the details?"

A stilted monster ran out from Fabriville under its own power. Four great girdered legs supported a housing the size of a freight car, and the legs moved on small tractor threads. Out it came, and it paused just outside the gate. A faint violet glow emerged from the bottom of the housing, and the whirling-skirling of Martian sands obscured the vastness of the space between the legs of the monster machine.

It moved again, and the original dust settled to disclose a very small but completely finished and furnished house. Around the encircling fence went the monstrous duplicator, and at each stop it dropped the carbon copy of the original house. Hour after hour it hummed, and when it completed the circle, Norton's mob was housed, fed and clothed.

And Norton knew that the "fence-building" job was but a test. For if the thing could build a house—

Venus Equilateral resounded and re-echoed from the force of the blast. It rocked, and precession tilted it away from its true north and south axial positioning. Men raced along the car-way to the blister laboratory and Channing led the wild rush.

The blister was gone. A shaken Wes Farrell clung to a stanchion, his face white behind the spacesuit mask. They fished him out of the wreckage and took him inside.

"Was making artificial elements," explained Wes. "Far outside of the Periodic Chart. I'd been stacking them over in a corner—they come in six-inch cubes, you know. But the last one—Bang!"

Channing shook his head. "That's dangerous," he said solemnly. "If you had a six-inch cube of every known element, would you stack 'em all side by side?"

"It might be all right—until you came to putting phosphorus on top of a hunk of iodin," said Walt.

"There's no reason to suppose that Wes didn't get a couple of very active elements side by each. We know nothing of the extra-charted elements. We can make 'em, but until we do, what can we know of 'em?"

"Well, we didn't lose the station," said Walt. "And business is so punk that tossing the beams won't harm us much; we'll have to spend some time aligning the place again."

"We're all here, anyway," agreed Don, looking over the ruined blister laboratory. "But look, Wes, I think you're running on the wrong gear. Anything that can be made with this gadget can be duplicated. Right?"

"What we need is a substance that will be stabilized under some sort of electronic pressure. Then it might come unglued when the matter-dingbat beam hit it. Follow?"

Wes Farrell thought for a few seconds. "We might make an electronic alloy," he said.

"A substance that is overbalanced as goes electrons. They will be inserted by concocting the stuff under extremely high electron pressure. Make it on some sort of station that has an intrinsic charge of ten to the fiftieth electron volts or so; that'll make queer alloys, I'll bet. Then it can be stabilized by interalloying something with a dearth of electrons. The two metals will be miscible, say, when liquid, and so their electron balance will come out even. They are cooled under this stress and so forth. When the disintegrator beam hits them, it will liberate the electrons and the whole thing will go plooey."

"Looks like a matter of finding the right stuff," said Walt. "Don, what about running the station charge up as Wes says?"

"No dice. The station is too big. Besides, the charge-changing gear would be overworked all over the station to maintain the charge, once made.

"We don't mind if we do," grinned Walt, winking at Don. "There'll be nothing didding about business until we get a medium of exchange."

The Reverend Thomas Doylen speared Keg Johnson with a fishy glance and thundered: "A plague on both your houses!"

Johnson grinned unmercifully. "You didn't get that one out of the Bible," he said.

"Sacrilege and blasphemy," exploded Doylen. "I came to plead with you. I wanted to bring you into the fold—to show you the error of your sinful way. And what do I find? I find, guarding the city, a massive facade of mother-of-pearl and platinum. Solid gold bars on gates which swing wide at the approach. A bearded man in a white cloak recording those who enter. Once inside—"

"You find a broad street paved with gold. Diamonds in profusion stud the street for traction, since gold is somewhat slippery as a pavement. The sidewalks are pure silver and the street-stop lights are composed of green emeralds, red rubies, and amber amethysts. They got sort of practical at that point, Reverend. Oh, I also see that you have taken your sample."

Doylen looked down at the brick. It was the size of a housebrick—but of pure gold. Stamped in the top surface were the words:

"My very good friend, it is intended to prove only one thing. Nothing—absolutely nothing—is worth anything. The psychological impact of the pearly gate and the street of gold tends to strike home the fact that here in Fabriville nothing of material substance is of value. Service, which cannot be duplicated, is the medium of exchange in Fabriville—have you anything to offer, Reverend?"

"The Lord saith: 'Six days shalt thou labor—' You have destroyed that law, Johnson."

"That's no law. That's an admonition not to overdo your labor. He didn't want us laboring seven days per. If He were running things under the present set-up, He'd be tickled pink to see people taking it easy five days per week, believe me."

"Is it? Am I being sacrilegious to believe that He has a sense of humor and a load more common sense than you and I?"

"Then He is far too busy to have heard that I mentioned Him in familiar terms. What is your point, Reverend? What do you want?"

"People will not come to church. They are too busy satiating themselves with the worldly goods and luxuries."

"Your particular private sect, like a lot of others," said Keg Johnson harshly, "has been catering to the wishful-thinking of the have-nots. That used to be all right, I suppose. You gave them hope that in the next life they could live in peace, quiet, and also in luxury, believe it or not. You call down the troubles of hell upon the shoulders of the ambitious, and squall that it is impossible for a rich man to get ahead in Heaven. Nuts, Reverend. You've been getting your flock from people who have no chance to have the pleasure of fine homes and good friends. You've been promising them streets of gold, pearly gates, and the sound of angelic music. Fine. Now we have a condition where people can have those—worldly goods—luxuries right here on earth and without waiting for death to take them there. If you want to start a return to church movement, Reverend, you might start it by making your particular outfit one of the first to eschew all this palaver about streets of gold. Start being a spiritual organization, try to uplift the poor in spirit instead of telling them that they will be blessed because of it. Don't ever hope to keep your position by telling people that material made with a duplicator is a product of Hell, Devil & Co., because they won't believe it in the first place and there won't be anything manufactured by any other means in the second place."

"And yet you have all of Mars under your thumb," scolded the Reverend Thomas Doylen. "Of what value is it to gain the whole world and lose your soul?"

"My soul isn't in bad shape," responded Keg cheerfully. "I think I may have done as much toward lifting civilization out of the mire as you have."

"Careful, Reverend. It is you that I am criticizing now, not God. Just remember this, people are not going to fall for a bit of salving talk when they want nothing. You promise them anything you like in the way of fancy embroidery, but they'll have it at home now instead of getting it in Heaven. Give 'em something to hope for in the way of greater intelligence, or finer personality, or better friends, and they'll eat it up.

"As far as having all of Mars under my thumb, someone had to straighten out this mess. I gave them the only thing I had worth giving. I gave them the product of my ability to organize; to operate under any conditions; and to serve them as I can. I'm no better off than I would have been to sit at home and watch the rest run wild. They'd have done it, too, if there hadn't been a strong hand on their shoulder. Where were you when the bottom fell out? Were you trying to help them or were you telling them that this was the result of their sinful way of life?"

The reverend flushed. "They wouldn't listen to my pleas that they forsake this devil's invention."

"Naturally not. Work with this thing and you'll come out all right. But you've got to revise your thinking as well as the rest of the world has had to revise theirs, or you'll fall by the wayside. Now good day, Reverend, and I wish you luck."

"Your argument may have merit," said the reverend, "though it is against the nature of things to fall in with any scheme without considerable thought."

"Think it over, then, and see if I'm not correct. I don't expect any immediate change, though, until you find that your former doctrines do not fit the people's wants now."

The reverend left, and as the door closed, a wave of pain swept through Keg Johnson's body. He reached for the telephone painfully and put a call through for the doctor.

"Make it three days with no mention of work. In five days you can have official visitors for three hours. In seven you may be up and around the hospital. You'll not be back there for eleven days."

"Put it off another day and you'll not be back at all," snapped Dr. Hansen. "Take it or leave it!"

"We'll take it out of your hide," said Hansen. "You're under the same rules as the rest of us. You do your day's work, and you receive the same medical blessing. Do you want to hoe the garden, or will you wash my car?"

"Nothing else but. Official order from the medical council. You'll play or else we'll have an interne take out that appendix."

Keg realized the sageness of the doctor's order by the time he reached the hospital. He was doubled over with pain and they did not permit him to walk from the car to the front door, but came out and got him on a stretcher. He was whisked inside, leaving Linna to straighten out the details at the incoming desk.

He went up to the operating room immediately, and the anaesthetic blacked him out from both pain and consciousness.

The days that followed were hazy; they kept him drugged because his energetic nature would have prevented rapid healing. It was four days after the operation that they gave him a quick shot of counter-drug that brought him out of the fog immediately.

"Hello," he said, looking up with a wry smile. "How many car washings do I owe you?"

"Plenty, brother. I tinkered for three hours over that frame of yours. Why did they have to run through an engineering change when they got to hanging your appendix in? I had to dig for it."

"That's the trouble with this system," Keg mumbled to Don. "He'll get the same credit for tinkering with me as he would for removing the cat's appendix."

"Nope. We came to give you a hunk of something interesting. Wes Farrell hauled it out of space, electrons, and considerable high-powered theory. Identium. Corrosion-proof, inert, malleable, but hard enough for coins, and you can roll it out into ten-thousandths sheets and use it for paper money. But don't ever put it into a duplicator. It'll blow the top right off of your roof if you do. There's our medium of exchange, Keg."

"The government is making the stuff in reams," said Don. "It won't be too long before you'll be able to pay Hansen what he's really worth, as well as the rest of your crew. But in spite of this trinket, Life has still made a big change. I can foresee the four-hour week right now."

"Someone had to help. I was doing nothing and so I pitched in to help Dr. Hansen when he worked on you. He said I did fine."

"Linna is a good nurse's aid," responded Hansen. "Mind if we keep her on a bit?"

"I want to, Keg," she said quietly. "With Marie wearing a platinum-mounted diamond tiara to dust the house, and Briggs coming to work in a limousine—imagine the idea of a butler's chauffeur!—and as you said, people eating from gold plates and using iridium tableware, there's nothing to get long-nosed about but one's inventiveness, talent, or uniqueness."

"Linna, you're an ace," grinned Keg. He smiled up at her and said, while waving the sheet of Identium before their faces, "do me a job, Linna. Go out and buy me back the spaceline."

"When the tumult and the shouting dies, fellers, we'll all be back in business again. Identium! The only thing you can write a contract on and not have it fouled or duplicated. The only thing you can write a check on, or use for credit. Identium—the first page of the new era—and when we get the mess cleared up Keg Johnson and Company will be carrying the mail! Linna, go out and buy me back my spaceline!"

Interlude:

An era of absolutely no want may give rise to concern about the ambitions of the race. Those who may wonder why the Period of Duplication did not weed all ambition out and leave the race decadent are missing one vital point.

They should ask themselves to consider the many reasons why men work, Keg Johnson himself can supply one line of reasoning—as follows:

Why do men work? Men often work because they must work in order to live. Then why do many men work hard, at long hours when there are easier ways of getting along? Because they have the desire to provide the best they can for their families. It is necessary to them to feel proud of the fact that they can do as well as they do. But remove the sheer necessity of toiling for food, clothing and shelter, and you make all men equally capable of supporting a family. Then come the ambitious ones who would appear a little better, a little more desirable, a little cleverer than their fellow man. This is not odious; it is the essence of ambition even though it sounds egotistic when mentioned in cold print.

And so when people all are well-clad, well-housed, and well-fed, there arises an almost universal ambition to become clever; to produce things that have not been duplicated by the machine.

For in a culture in which fifty thousand copies of Leonardo da Vinci's Last Supper hang, in theatres, churches, schools, and living rooms, he who possesses a hand-made chromo painted by his own hand owns a true Unique to which he can point with pride.

On Venus Equilateral, they worked, too. Given more time for leisure, they took more time for study and experiment.

Of course, it was only a matter of time before someone came up with something that would put Venus Equilateral on the obsolete list. Venus Equilateral had been instrumental in putting a number of other things on the retired list—and the Relay Station itself was long overdue.

And, too, there was still one man who would give his black soul to see Venus Equilateral lose out....

Mad Holiday

Walt Franks chuckled. "I bet you've been making synthetic elements again with the heterodyned duplicator."

Farrell nodded. "I've found a new series sort of like the iron-nickel-cobalt group."

Channing shook his head. There was a huge permanent magnet that poured a couple of million gauss across its gap, and in this magnetic field Farrell had the crystal supported. A bank of storage batteries drove several hundred amperes—by the meter—through the crystal from face to face on another axis, and down from above there poured an intense monochromatic light.

"Trouble is," complained Wes, "that there isn't a trace of a ripple in any of the three factors that work on the thing. Permanent magnet, battery current, and continuous gas-arc discharge. Yet—"

Walt Franks disappeared for a moment. He returned with a portable phonograph, which caused Don Channing to grin and ask, "Walt, are you going to make a recording of this conversation, or do you think it will dance to a Strauss waltz?"

"It's slightly bats, so I brought the overture to Das Fledermaus for it," snorted Franks. As he spoke, he removed the pick-up from the instrument and added a length of shielded wire. Then he set the stylus of the phonograph against the faintly vibrating crystal and turned up the gain.

Wes Farrell threw up his hands. "I can state with positiveness that there isn't any varying field of anything that I know of that is at that frequency."

Walt turned the dial of an audio generator until the note was beating at zero with the vibrating crystal. "What frequency does Arden's jello work at?" he asked. "I've got about four-fifty per second."

"Taking my name in vain?" asked a cool and cheerful contralto. Don whirled and demanded, "How long have you been keyhole listening?"

Arden smiled. "When Walt Franks nearly runs me down without seeing me—and in his great clutching hands is a portable phonograph but no records—and in his eye there is that wild Tom Swift glint—I find my curiosity aroused to the point of visible eruption. Interesting, fellers?"

"Baffling," admitted Channing. "But what were you doing standing on odd-corners waiting for Walt to run you down for?"

"My feminine intuition told me that eventually one of you would do something that will wreck the station. When that happens, my sweet, I want to be among the focus of trouble so that I can say I told you so."

Walt grunted. "Sort of a nice epitaph," he said. "We'll have them words 'I tole ya so' engraved on the largest fragment of Venus Equilateral when we do."

Franks swelled visibly and pompously. "Why, of course," he said with emphasis. "Some of my best friends are women!"

Arden stuck her tongue out at him. "I like you, too," she said. "But you wait—I'll fix you!"

Walt thought seriously for a moment. "The drinks are on me," he said. "And I'll explain when we get there. Game? This is good." Insistent, Walt led them from Wes Farrell's laboratory near the South End skin of Venus Equilateral to Joe's, which was up nine levels and in the central portion of the station. "Y'know," he said, "women aren't so bad after all. But I've got this feminine intuition business all figured out. Since women are illogical in the first place, they are inclined to think illogical things and to say what they think. Then if it should happen to make sense, they apply it. I used to know an experimenter that tried everything he could think of on the theory that some day he'd hit upon something valuable. Well—this is it, good people."

Walt shoved the door open and Wes Farrell grinned as he always did at the sign that read:

Arden entered and found a place at the long bar. The three men lined up on either side of her and Joe automatically reached for the Scotch and glasses.

Walt lifted his glass. "I drink to the Gods of Coincidence," he chanted, "and the Laws of Improbability. 'Twas here that I learned that which makes me master of the situation now."

Arden clinked her glass against his. "Walt, I'll drink to the Gods of Propinquity. Just how many problems have you solved in your life by looking through the bottom of a glass—darkly?"

A strange look came over his face. He spluttered. He grew a bit ruddy of face, made a strangling noise, and then choked.

Don took a very cautious sip and made a painfully wry face. "The SPCS—Society for the Prevention of Cruelty to Scotch—should dip their tongue in this," he said.

Arden smelled gingerly. "Don," she asked him seriously, "have you been petting dragons?"

Wes, chemist like, dipped his forefinger in the drink, diluted it in a glass of water, and touched it to his tongue. "It'll never be popular," he said.

Joe turned back to his duplicator and shoved a recording into the slot. The machine whirred for a few seconds, and Joe opened the door and took out the new bottle, which he handed to Walt. Walt cut the seal and pulled the cork, and poured. He tasted gingerly and made the same wry face.

Wes Farrell nodded. "Probably re-arranged some of the molecular patterns in the recording," he said.

Joe put both bottles in the duplicator and turned the switch. They disappeared in seconds, and then Joe took another recording and made a bottle of a different brand. Again Walt tasted gingerly, smiled hugely, and took a full swallow.

"Whew," he said. "That was almost enough to make a man give up liquor entirely."

"And now," said Don Channing, "let us in on your big secret—or was this just a ruse to get us in this gilded bistro?"

Walt nodded. He led them to the back of the bar and into the back room. "Refrigerator," he said.

"I didn't really mean—" continued Arden, but her voice died off, trailing away into silence as Walt, motioning them to come in, also put his finger on his lips.

And then in the deep silence caused when the heavy door shut off the incident sounds from Joe's restaurant and bar, there came a faint, high-pitched hum.

Don turned to Arden. "That it?" he asked. "You've got better pitch-sense than I have."

"Cold in here," said Wes. He swung open the door and they returned to the bar for their drink. "We can establish its identity easily enough," he told them. He finished the drink, and turned from the bar. "Walt, you bring the pick-up and amplifier; Don, you carry the audio generator, and I'll bring up the rear with the rest of the gadget."

"I didn't mind when they used the tablecloths to draw on," he said. "I didn't really object when they took the tablecloths and made Warren use 'em as engineering sketches to make things from. But now, dammit, it looks like they're going to move into my refrigerator and for God knows what! I give up!"

"Don't mind if I do," chuckled Joe laconically. "If I'm to be shoved out of mine own bailiwick, I might as well enjoy these last few days."

He was finishing the drink as the technical section of Venus Equilateral returned, laden with equipment.

Arden shrugged. "Here we go again," she said. "Once more I am a gadget widow. What do you recommend, Joe? Knitting—or shall I become a dipsomaniac?"

Arden finished her glass in one draught, and a horrified expression came over her face. "One like Don is all I can stand," she said in a scared voice. Then she smiled. "It's the glimmering of an idea, though," she added with brightening face. "It stands a fifty-fifty chance that it might turn out to be a girl—which would scare Don to death, having to live with two like me."

Walt Franks re-appeared, headed out of the restaurant, and returned a few minutes later with another small case full of measuring equipment.

"And this," said Arden as Walt vanished into the refrigerator once again, "will be known as the first time Walt Franks ever spent so much time in here without a drink!"

Half way from Lincoln Head to Canalopsis, Barney Carroll was examining a calendar. "Christmas," he said absently.

"On Terra, where Christmas originated? Where Christmas trees adorn every home, and the street corners are loaded with Santa Clauses? Where—"

"Christmas is a time for joy," said Christine. "Also to the average party, Christmas means snow, wassail, and friends dropping in. Me, I'm acclimated—almost—to this chilly Martian climate. Cold weather has no charm for your little sister, James."

"Oh?" repeated Barney. "Okay, woman, we get it. Instead of the cold and the storm you'd prefer a nice warm climate like Venus?"

"Or even better," said Jim Baler to Barney Carroll, "we might visit Venus Equilateral."

Christine's evasive manner died. "Now," she said, "you've come up with a bright idea!"

Barney chuckled. "Jim," he said, "call Walt Franks and ask him if he has a girl for us?"

"We'll drop in quietly, surprise-like," announced Christine. "And if there's any little black book, I'll see that you two Martian wolves divide 'em evenly."

"Walt is going to hate us for this," chuckled Jim. "Accessories to the fact of his lost bachelorhood. Okay, Chris, pack and we'll—"

"Pack nothing," laughed Christine. "I've packed. For all three of us. All we need is our furs until we get to Canalopsis. Then," she added happily, "we can dress in light clothing. I'm beginning to hate cold weather."

Christine nodded. "The Martian Girl leaves Canalopsis in about three hours. We pause at Mojave, Terra, for six hours, and thence to Venus Equilateral on the special trip that takes Christmas stuff out there."

Jim Baler shrugged. "I think we've been jockeyed," he said. "Come on, Barney, needs must when a woman drives."

"No difference," said Jim, and then he ducked the pillow that Christine threw at him.

"The Joe-Section of the engineering has been completed," said Arden with a grin. "They nearly drove Joe nuts for about a week."

"What were they doing?" asked Jim. "Building an electronically-operated Martini?"

"When I tell you, you won't believe me," said Arden. "But they've been living in Joe's refrigerator."

Arden paused in front of three doors on the residence level near her apartment and Jim, Christine, and Barney each put their traveling bags inside. Then Arden led them high into the station where they came to a huge bulkhead in which was a heavy door.

From the inside of the vast room came Don, Walt, and Wes. They were clad in heavy furs and thick gloves, Channing was carrying a small pair of cutters that looked a bit ridiculous in the great glove.

"Merry pre-Christmas," said Jim. Don whipped off a glove and Jim wrung his hand unmercifully. Wes Farrell greeted Barney Carroll jovially, while Walt Franks stood foolishly and gaped at Christine Baler.

Christine looked the heavy clothing over and shook her head. "And I came here to be warm," she said. "Come out from behind that fur, Walt Franks. I know you!"

"It all started in Joe's refrigerator," said Wes. "We found that the cold had crystallized a bit of metal in the compressor. We discovered that it was radiating one of the super-frequencies of the crystal-alloy level. When warm it didn't. So we've set up this super-cooler to make checks on it. Looks big."

Channing waved toward the door. "We've got the ultimate in super-coolers in there," he said. "Remember the principle of the sun-power tube—that it will drain power out of anything that it is attuned to? Well, we're draining the latent heat-energy out of that room with a power-beam tube—actually we're transmitting it across space to Pluto."

"Uh-huh. In effect, it is like trying to warm Pluto from the energy contained in that room. Obviously we aren't going to melt much of the solid-frozen atmosphere of Pluto nor create a warm and habitable planet of it. We can run the temperature down to darned near Nothing Kelvin without doing much of anything to Pluto."

"We're below the black-body temperature of Mars right now," said Walt. "And the gadgetry is working so much better that we're going to run it down to as far as we can get it."

"Why, it looks as though we can make a set of crystals that will permit instantaneous communication from one to the other."

Christine looked at the thermometer set in the face of the door. She turned back to the others and shook her head vehemently.

"For medicinal purposes only," agreed Barney. "It's been deadly cold on Mars—about a quart and a half of sheer and utter cold."

"Been cold in there, too," said Don. "Arden, you're out of luck—you've stayed out of the cold."

"You try to freeze me out of this session," said Arden, "and you'll find that I have the coldest shoulder in the Solar System."

As the party from Mars left the platform of the spacecraft that was poised on the Landing Stage of Venus Equilateral, another landing was made. This landing came from the same ship, but unlike the arrival of the Balers and Barney Carroll, the later landing was unseen, unknown, and unwanted.

Now, most stowaways are apprehended because success in such a venture is difficult. To properly stow away, it is calculated that more than the nominal cost of the trip must be spent in planning and preparation. Also, there is the most difficult of all problems—that of stepping blithely ashore under the watchful eye of purser or authority whose business it is to see that all the passengers who embarked ultimately disembark—no more and no less; plus or minus zero. (It is considered that an infant born aboard ship is a legal passenger and not a stowaway. This is a magnanimity on the part of the transportation companies who understand that they might have difficulty in persuading any court that the will exists to defraud the company of rightful revenues, etc.) (A death and burial at sea is also ignored; the transportation company has already collected for a full fare!)

But Mark Kingman had done it. He had come aboard in a large packing case, labelled:

CERTIFIED UNIQUES!
(Identium Protected)
Under NO Circumstances
will
DUPLICATOR
or
MATTER TRANSMITTER
Be Tolerated

With magnificent sophistry, Kingman was within the letter of the law that did not permit false representation of contained merchandise. For he, a human being, was a certified unique, he having never been under the beam of the integrator scanning beam of the matter duplicator or transmitter. Nor had any other living human, for that matter. The identium protection was insurance on all such cargoes; it prevented some overly—or underly bright clerk from slipping the package into a duplicator to make shipping easier. Identium exploded rather violently under the impact of the scanner beam, it will be recalled.

Along with Kingman was a small battery-powered duplicator, and a set of recordings. The duplicator produced fresh air as needed, water, food, and even books, games, and puzzles for solitary entertainment. Waste material went into the matter bank, proving the earlier statements that with a well-equipped duplicator and a set of recordings, any man can establish a completely closed system that will be valid for any length of time desired.

When the ship landed, Kingman tossed all the loose material into the duplicator and reduced it to nonhomogeneous matter in the matter bank. Then he turned the duplicator-beam against the side-wall of the huge box and watched the side-wall disappear into the machine.

He stepped out through the opening, which was calculated to miss the concealed plates of identium installed to prevent just this very thing. Kingman, of course, had planned it that way.

Once outside, Kingman set the duplicator on the deck between other cases and snapped the switch. The scanner beam produced books from Kingman's own library which he packed in the case. Then by reversing the direction of depth scan without changing the vertical or horizontal travel, Kingman effected a completed reversal of the restoration. The side of the packing case was re-established from the inside out, from the original recording which, of course, was made from the other side. It re-formed perfectly, leaving no seam.

Kingman went down an unused shaft to the bottom of the ship, where he drilled down with the duplicator through the bottom of the ship where it stood upon the Landing Stage. Down through the stage he went and into a between-deck volume that was filled with girders.

By the time that the party had adjourned to Joe's, Mark Kingman was high in the Relay Station, near the center line and a full mile and a half from the Landing Stage. He was not far from the vast room that once contained a lush growth of Martin Sawgrass, used before the advent of the duplicator, for the purification of the atmosphere in Venus Equilateral.

He was reasonably safe. He knew that the former vast storages of food and supply were no longer present, and that being the case, few people would be coming up to this out of the way place almost a third of a mile above the outer radius of the station where the personnel of Venus Equilateral lived and worked.

He started his duplicator and produced a newly charged battery first. He tossed the old one into the matter bank. He'd have preferred a solar energy tube, but he was not too certain of Sol's position from there and so he had to forego that.

Then he used the duplicator to produce a larger duplicator, and that duplicator to make a truly vast one. The smaller numbers he shoved into the larger one.

From the huge duplicator, Kingman made great energy-beam tubes and the equipment to run them. Taking his time, Kingman set them up and adjusted them carefully.

Then a complete connection was established between an area high in the station but a good many thousand feet away—and on the other side of the central axis—through the energy-beam tubes, and a very distant receptor tube on the planet Pluto.

His final act before relaxing completely was to have the huge duplicator build a small but comfortable house, complete with furniture and an efficient heating plant. Then he settled down to wait for developments.

"Christmas," said Barney. "We—Christine—thought that it might be nice to spend Christmas with old friends in a climate less violent than Mars."

"Frankly," grinned Jim Baler, "my charming sister has set her sights on your bachelor playmate."

"I think it is mutual," said Arden. "After all, Walt has had a lot of business to tend to on Mars. He used to use the beams to conduct business—in fact he still does most of it by communications when it isn't Mars—but give him three ten-thousandths of an excuse and he's heading for Canalopsis."

"We've just set up a modulator," said Wes. "I'm modulating the current since the magnetic field is supplied by a permanent magnet and the monochromatic light comes from an ion arc. Using varying light seems to widen the response band with a loss in transmission intensity. This way, you see, all the energy going into the crystal is transmitted on a single band, which is of course a matter of concentrated transmission."

"That sounds sensible. Also, if this gets to sounding practical, it is quite simple to establish and maintain a high-charge permanent magnet field, and also a monochromatic light from a continuous gas-arc. Easier, I'd say, than making ammeters all read alike."

"Utopia," said Wes Farrell, "is where you can use any handy meter and find it within one tenth of one percent of any other—including the Interplanetary Standard."

Channing observed that Utopia was far from achieved. Then he said: "You've got the Thomas gents out in a ship with another crystal set-up?"

"Anopheles," said Farrell. "Will shortly head for Mars with the other half of the gear in another refrigerated compartment. If this proves practical, Pluto is going to become useful."

Arden nodded absently. "I've always claimed that there is a practical use for everything."

Channing opened his mouth to say something and had it neatly plugged by Arden's small hand. "No, you don't," she said. "We've all heard that one."

"The one about the navel being a fine place to hold the salt when you're eating celery in bed," said Arden. Channing removed Arden's hand from his mouth and placed it in hers. "You done it," he told her ungrammatically. "For which I'll not tell you what Walt and Christine are doing right now."

Arden's attempt to say, "Pooh. I know," was thoroughly stifled and it came out as a muffled mumble.

Farrell nodded. "I noted that the energy entering the crystal was not dissipated as heat. Yet there was quite a bit of energy going in, and I wanted to know where it was going. Apparently the energy going in to the crystal will only enter under the influence of a magnetic field. Changing the field strength of the magnet changes the band, for the transmission to the similar crystal ceases until the other one has had its magnetic field reduced in synchronous amount. Also, no energy is taken by the crystal unless there is an attuned crystal. The power just generates heat, then, as should be normal.

"So," said Wes thoughtfully, "the propagation of this communicable medium is powered by the energy going into the crystal. Crystals tend to vibrate in sympathy with one another; hitting one with a light hammer will make the other one ring, and vice versa. I've tried it with three of them, and it makes a complete three-way hookup. As soon as Chuck and Freddie Thomas get out a good way, we'll be able to estimate the velocity of propagation, though I think it is the same as that other alloy-transmission band we've been using."

Farrell winced. That argument was still going on, whether or not you could square a velocity. "We'll know," he said quietly.

The loudspeaker above Farrell's desk hissed slightly, and the voice of Freddie Thomas came in: "I'm about to trust my precious life once more to the tender care of the hare-brained piloting of my semi-idiot brother. Any last words you'd like to have uttered?"

Wes picked up a microphone and said: "Nothing that will bear transmission under the rules. If there's anything I want to tell you, I'll call you on this—and if this doesn't work, we'll try the standard. They're on your course?"

"Well, if you jiggle any, call us," said Farrell, "either on the standard space phone or this coupled-crystal set-up."

Freddie laughed. "We never did settle on a name for the driver-radiation communication system. So we're starting this one off right. It's the Coupled-Crystal Communicator. For short, 'Seesee', see?"

Chuck Thomas chimed in. "My semi-moronic brother will delay this take-off if he doesn't sharpen up," he said. "What he means is: Seesee, get it?"

And they did get it. Hour followed hour and day followed day from take-off to turnover, where there was no Doppler effect even though the velocity of the ship was fiercely high.

The hours fled by in a working flurry of tests and experiments and almost-constant talk between the arrowing ship and Venus Equilateral....

"Maybe—and maybe not," said Walt. "The big thing is that things should behave according to rules. When they do not, then's when people make discoveries that lead to new rules."

"Well, in this case we know to several decimal places the heat equivalent of electrical energy. Three thousand, four hundred thirteen kilowatt hours equals one B.T.U.—a British Thermal Unit. We know the quantity of electrical power—the number of kilowatts—being coursed through the tubes en route to Pluto. We know by calculation just how many calories of heat there are in the area we're cooling off—and therefore we can calculate the time it will take to reduce the temperature of that area a given number of degrees centigrade. We're about double."

"Oh—yes. Well, for a number of years—several thousand, in fact—it was taught that a heavy mass falls faster than a light mass. Then Galileo tossed rocks off of the Tower at Pisa and showed that a small stone and a large stone fall equally fast. That was a case where definitely provable evidence was at variance with the rules. They couldn't revise the actuality, so they had to revise the rules."

"I see. And now because that area is cooling off much faster than anticipated, you anticipate that something is not behaving according to the rules?"

"Thank you, kind sir," laughed Christine. "But remember that I was raised in a bright family."

Walt nodded. "You'll get used to it," he said absently, collecting a few instruments.

"Look, Walt," said Christine in a scathing tone, "I'm used to it! That's why I came to Venus Equilateral from Mars. Remember?"

Walt looked at her, wondering. But Christine wore a smile that took most of the sting out of her words.

"Lead on, Walt. I can take a bit of chill. In fact," she said with a half-smile, "under the proper circumstances, a bit of chill is fun."

Walt finished collecting his equipment and packed it into two carrying cases. Then from a closet, he took electrically warmed clothing, helped Christine into hers, climbed into his own, and then they took the long trek along corridors and up elevators to the cold room.

"The room leaks bad," said Walt. "Wes Farrell's hobby these days is making synthetic elements on the duplicator—he uses a filter to get a mono-atomic pattern and then heterodynes the resulting signal to atomic patterns above the transuranic system. But in all of Wes Farrell's playing at making synthetic transuranic elements, he hasn't come up with anything like a good heat insulator yet. We did toy with the idea of hermetically sealing in a double wall and piping some of the vacuum of interstellar space in there. But it was too vast a project. So we let some heat leak and to hell with it."

Christine shuddered. "I've never really appreciated the fact that Venus Equilateral is really just a big steel capsule immersed in the vacuum of interplanetary space," she said. "It's so much like a town on Terra."

"Inside, that is," grinned Walt. "There's a nice queasy thrill awaiting you when first you stand in an observation blister made of plastiglass."

"Because first you are terrified because you are standing on a bubble that is eminently transparent and looking down beneath your feet, you see the stars in the sky. You know that 'down' to the working and residence section of the station is actually 'out and away' from the axis of the station, since it revolves about the long axis to provide a simulated gravity plus gyroscopic action to stabilize the beam-stage and pointers. Well, when you go down—and again 'Down' is a relative term meaning the direction of gravitic thrust—into one of the blisters, your mind is appalled at the fact that your feet are pressing against something that your eyes have always told you is 'up'. The stars. And then you realize that between you and the awesome void of space in just that thin glass.

"You end up," he grinned, "being very careful about banging your heels on the floor of the station for about a week."

"You'll still go through it," he told her. "But just remember that anybody on the other side of the station, standing in a similar blister a mile 'above' your head, is standing feet 'upward' with respect to you. But he, too, is being thrown out and away by centrifugal force."

Walt put his equipment down and rummaged through it. He selected a supersensitive thermocouple and bridge and fixed the couple to one of the fixtures in the room. He balanced the bridge after the swinging needle came to a halt—when the thermocouple junction had assumed the temperature of the fixture. "Now," he said, "we'll read that at the end of a half hour and we'll then calculate the caloric out-go and balance it against the kilowatts heading out through the energy beam."

"In the meantime, we measure the electrical constants to within an inch of their lives," he told her. "I've got a couple of real fancy meters here—this one that I'm hooking across the original wattmeter in the circuit measures the wattages in the region between one hundred thousand kilowatts and one hundred ten thousand kilowatts. Designed especially as a high-level meter."

Walt clipped the portable meters in place and made recordings. Finally he nodded. "Right on the button," he said. "Just what the meters should read."

The crystal began to vibrate faintly, and Walt mentioned that either Wes Farrell was calling Freddie Thomas or vice versa. "Can't hear it very well," complained Walt, "because Wes has the amplifiers downstairs, both incoming amplifier from the dynamic pick-up—we had to give up the standard crystal because it is expected to get cold enough to make the crystal too brittle—-to the modulating equipment. The monitor-speaker is outside—we haven't been in here enough to make use of it since our first tries."

Walt took a look at the bridge on the thermocouple and nodded vaguely. He killed more time by showing Christine the huge tube that drained the latent heat out of the room and hurled it across the solar system to Pluto.

"Y'know," he grinned as a thought struck him, "I think we've licked the Channing Layer that so neatly foiled Mark Kingman and Terran Electric on that solar power project."

"Sure," he said. "All we do is set up a real beam-input device on the moon, for instance, and then use a batch of these things to draw the power from there."

"That'll have to be checked," said Walt. "For Pluto hasn't got a Channing Layer, of course, and our station out there is no criterion. But you note there is no smell of ozone in here. That leads me to think that w've given Terran Electric the runaround once more. Funny thing about Kingman, if someone gave him this development, he'd never think of reversing it to bring energy in."

"From what I know of the man," said Christine, "he'd not think of reversing, but he would think of perverting."

Walt tried a bit of Indian War Dance but failed because the pseudo-gravitic force was too light to hold him down. They were too close to the axis for full force.

Walt laughed hugely and hugged her. Christine was lissome in the curve of his arm as she relaxed against him.

Walt looked down at her for what seemed to be a long time while the stream of highly-technical thinking and deduction gave way to a series of more fundamental thoughts. Then he added his other arm to the embrace, and Christine turned to face him. He kissed her gently; experimentally—and discovered instead of resistance there was co-operation. His kiss became fervent and Christine's lips parted beneath his.

Some minutes later, Christine leaned back in his arms and smiled at him affectionately. "I was wondering if you'd ever get around to that," she said softly.

"Shucks, why not just have him threaten to sit on me?" asked Walt. He kissed her again.

"Now," she said after an appropriate and pleasant interval, "just what was my 'thought for the week'?"

"We've no corner on brains," said Walt. "Anybody tinkering with these energy tubes might easily devise the same thing. Kingman's immediate thought would be to freeze us out, I betcha."

Walt kissed her again and then let her go, "Let's do some juggling with figures," he said.

"The Laws of Probability aided by a bit of sheer guesswork and some shrewd evaluation of the barrister's mind."

"I know," he replied, reaching for his bag of gear, "but there's a lady present."

"You forget that the lady thought of it," Christine pointed out. "So let's go and find the—barrister."

"It ought to show, though," observed Walt. "And yet, my lady, we can check whether there has been cross-duggery at the skull-roads by making a brief observation along here somewhere."

"You think that if Kingman were trying to chill-off the place, he'd have bollixed the thermostats so they can't heat up the place and compensate?"

Walt nodded. "He'd do it, not knowing that we had all the near-by circuits shut off for our own experiment, no doubt."

"You don't suppose Kingman knew about this idea and decided to add to the general effect?" asked Christine.

Walt shook his head. "He'd assume that someone would be rambling up here off and on to look at the works. He'd automatically choose another place if he thought we had this one under observation."

Walt stopped at the thermostat and with a screwdriver he removed the face of the instrument. He reached down into his tool-pocket and took out a long, slender pair of tweezers. He probed in the depths of the thermostat and come out with a tiny square of paper.

"Stickum on one side held it until the contacts closed," he said. "Then it made a darned good insulator. Betcha this slip of paper came from Terran Electric!"

"I'm going to call Don," said Walt. "Iffen and providen we can find a live jack." He took a handset from his kit of tools and plugged it into the jack below the thermostat. He jiggled a tiny switch and pressed a little red button, and after a full three minutes, he said "Damn," under his breath and dropped the handset back into his tool kit.

"Nobody's paying much attention to the telephone from this section of Venus Equilateral any more," he said. "There's a live one in the cold room, though. Let's take a look around first."

Walt thought for a moment. "We set the cold room about one-third of the way from the North End because it was as far from the rest of the station's operating and living section as possible while commensurable with being reasonably close to the labs," he said. "We're not very far—perhaps a hundred yards from the axis. We're about a mile from the North End.

"Now, if I were Kingman, I'd set up shop in some place as far from the operating section as possible commensurable with an out of the way place—and definitely far from the laboratories. Then I'd select a place as far from me as I could get without too much danger of having the effect detected."

Christine nodded. "If Venus Equilateral were a cube, you'd take one corner and chill off the opposite corner."

"Venus Equilateral is a cylinder, and the skin is filled with people. However, you can set up an equation in differential calculus that will give you two spots as far from one another as possible with the least danger of detection from the ends or skin of a cylinder. The answer will give you two toroidal volumes located inside of the cylinder. You set your workshop in one and start the chill-off in the other—and right across the center from you."

"We used the same equation to locate the least dangerous place. Predicated on the theory that if the personnel need be protected from the danger area as much as the danger area need be concealed from people, we can assume the use of the same constants. Now, since by sheer coincidence Markus the Kingman selected a spot in the toroid that we also selected, it narrows our search considerably."

"In other words, we chase down the length of the station, cross the axis, and knock on Kingman's door."

And being firmly convinced that mixing pleasure with business often makes the business less objectionable, Walt kissed Christine once more before they started toward the place where they expected to find their troublemaker.

"How are we going to find him?" asked Christine. The corridor was long and die-straight, but both walls were sheer for thirty feet and unbroken.

"Look, I guess," said Walt, uncertainly. "I'm not too familiar with this section of the station. When I was first here—many years ago—I spent a lot of spare time roaming and exploring these seldom-used corridors. But my Boy Scout hatchet wouldn't cut trail-blazes on the steel walls."

He laughed a bit thoughtfully, and then he put his hands to his mouth, cupping them like a megaphone, and he yelled:

"Might scare him into action," said Walt. "Easiest way to shoot pa'tridge is to flush it into the open. Otherwise you might walk over a nest and never see it. I—Holy Grease!"

A four foot section of the wall beside them flashed into nothingness with neither sound nor light nor motion. It just disappeared. And as they goggled at the vacant square, an ugly round circle glinted in the light and a sourly-familiar voice invited them in—or else!

"Well," said Walt Franks, exhaling deeply. "If it isn't Our Legal Lamp himself!"

"It was just a matter of time before you dropped all pretense of being thinly legal," said Walt scathingly. "Give you credit, Kingman, for conducting yourself as close to the line without stepping over for a long time. But now you can add breaking and entering to kidnaping to whatever other crimes you have committed."

Kingman smiled in a superior manner. "I might," he said suavely, "add murder. There would be no corpus delicti if both of you were fed into the duplicator."

Then Kingman snapped the switch on the duplicator and the wall was re-established. Then he forced Christine to tie Walt, after which he tied Christine and then checked and added to Walt's bonds from a large roll of friction tape. He dropped them side by side in chair, and taped them thoroughly.

"You are a damned nuisance," he said. "Having to eliminate you tends to decrease my enjoyment at seeing the failure of Venus Equilateral. I'd have preferred to watch all of you suffer the hardest way. Killing you leaves fewer to gloat over, but it must be done. Once you found me, there is no other way."

"Walt," pleaded Christine, "won't the others find the same thing and follow us?"

Walt wanted to lie—wanted desperately to lie, if for no other reason than to spare Christine the mental anguish of expecting death. But Walt was not a good liar. He gave up and said: "I happen to be the guy who rigged the thermal-energy tube—and I'm the only guy who knows about the too-fast drop. All I hope for is that we'll be missed."

Kingman laughed nastily and began to fiddle with the scanning-rate controls on his duplicator.

Arden came running into her husband's office breathlessly. She was waving a sheet of paper and there was mingled anger and pleasure on her face as she shoved the paper under Don's eyes and waggled it. "Look!" she commanded.

"Stop fanning me with that," said Channing, "and let me see it if it's so all-fired important."

Channing pried his wife's fingers apart and took the paper. He read—and his eyes bulged with amused concern—

"Well," chuckled Don good-naturedly, "that's Our Walt. He never did do anything the slow and easy way. Does Jim know?"

They found Jim and Barney in Farrell's laboratory discussing the theories of operating a gigantic matter-transmitter affair to excavate sand from a cliff. Channing handed the note to Jim, who read it with a half smile and handed it to Barney, who shared it with Wes while they read it together. Jim said "I'm not surprised; Christine could have been talked into wedlock—holy or unholy—by a mere wink from Walt."

"I hope she'll be kind to our little bucket-headed idiot," said Arden, making to wipe tears with a large sheet of emery paper from Farrell's workbench. "He's been slightly soft-skulled ever since he set eye on that scheming hussy you have for a sister."

"This," chuckled Don Channing, "is one mess that Walt will have to get out of himself."

"Mess is it?" demanded Arden with a glint in her eye. "Come, husband, I would have words with thee."

Don shook his head. "If I just give you the checkbook, you'll use it reasonably sparing, all things feminine considered. But gawd help the balance once you get to talking me into writing the check myself. Besides, we're about to hear from the Thomas boys again. They're about to land at Canalopsis."

It took about ten minutes, and then Freddie Thomas's voice came from the speaker, loud and clear. "Well, we've landed. We're here. And where are you?"

"Hang on, Freddie," replied Farrell. "And we've some news for you. Walt Franks and Christine Baler have just committed matrimony."

"They eloped; left a note; took the Relay Girl unbeknownst to all and sundry. Left their damned note right where the Relay Girl's landing space was."

Chuck's voice came in. "He probably will," he observed. "And you know, when I think of spending Eternity with my brother, it's enough to make a guy spend an exemplary life in the hope of going to Heaven so we can be apart. But I've got another guy here that might be interested."

"No, but I'm darned interested in this coupled-crystal gadget of yours. Mind if I bring Linna out for a few days?"

Keg Johnson laughed. "Not a chance, Don. I own a spaceline, remember? And not wanting to cast disparagement at your type of genius, but I'll prefer riding in style at two gravities instead of blatting all over the sky at five, ducking meters and festoons of cable; eating canned beans off a relay-rack shelf standing up; and waking up in the morning to the tune of Chuck Thomas carving a hole through the bedroom wall to make a straight-line half-wave dipole that won't quite fit in otherwise."

"I'd send the Relay Girl," said Don, "but it seems as how my old side-kick, Walt Franks, swiped it to locate a justice of the peace in the company of a young and impressionable gal named Christine."

"Right," answered Channing, and Wes Farrell took the microphone to give the Thomas boys some information.

Mark Kingman emerged from his tiny house in the huge storeroom and his breath blew out in a white cloud. He went to the couple tied to their chairs and said: "Cold, isn't it?"

"You know," said Kingman, "those batteries are going to wear out sooner or later. I'd remove them and let the cold do its work excepting for the fact that I'd have to loose you and get into the inside pocket of the suits. You stay tied!"

"Having nothing to eat but your words is beginning to undermine my health," snapped Walt. "Gonna starve us to death too?"

"Oh," said Kingman expansively, "I've been devising a machine for you. As an inventor of note, you will appreciate Little Joe. He will take care of you both, to keep you alive until the cold gets you."

He returned to his little house and emerged with a large, complicated gadget that he trundled to position in front of Walt and Christine. There was a large hopper above and a wild assortment of levers and gears interlocked in the body of the mechanism.

And from the insides of the thing a lever speared forward. A spoon was welded to the fore end, and it carried a heaping load of mushy something-or-other.

Walt blinked and tried to duck, but his bindings wouldn't permit too much freedom of motion. The spoon hit him on the cheek, cutting him and spilling the food on his chest. The spoon disappeared back into the machine.

It re-appeared on the other side and sliced towards Christine, who screamed in fright. The spoon entered her opened mouth, and the stuff it hurled into her throat nearly strangled her. It came again at Walt, who miscalculated slightly and received a cut lip and a mouth full of heavy gruel.

And then the thing accelerated. The velocity of repetition increased by double—then decreased again—and then started on random intervals. They could never be certain when the knifing spoon would come hurtling out of the machine to plunge into the position where their mouths should be. They were forced to swallow quickly and then sit there with mouth wide open to keep from getting clipped. With the randomness of interval there came another randomness. One spoonful would be mush; the next ice-cream; followed by a cube of rare steak. The latter was tough, which demanded jaw-aching rapid chewing to get set for the next possible thrust.

"A balanced diet," chortled Kingman, rolling his eyes in laughter. He held his stomach at the sight.

"It won't be long now," said Kingman. "Your cold room is down to almost absolute zero row. You know what that means?"

"When the metal reaches absolute zero, as it will with the thermal beam, the spread of cooling will accelerate. The metal will become a superconductor—which will superconduct heat as well as electricity. The chill area is spreading rapidly now, and once this cold room section reaches absolute zero, the chill will spread like wildfire and the famous Venus Equilateral Relay Station will experience a killing freeze."

Walt glared. There was nothing else he could do. He was being fed at a rapid rate that left him no time for other occupations. It was ignominious to be so treated, but Walt consoled himself with the fact that he was being fed—even though gulps of scalding-hot coffee drenched spoons of ice cream that came after mashed potatoes (with lumps, and where did Kingman get that duplicator recording?). The final blow was a one-inch tube that nearly knocked their teeth out in arriving. It poured a half pint of Benedictine and brandy down their throats which made them cough—and which almost immediately left them with their senses reeling.

Kingman enjoyed this immensely, roaring with laughter at his 'feeding machine' as he called it.

Then he sobered as Walt's eyes refused to focus. He stepped to a place behind Walt and unbound him quickly. Walt tried to stand, but reeled, and Kingman pointed his heavy rifle at Walt from a very safe distance and urged him to go and enter the small metal house. Walt did. Then Kingman transferred Christine to the house in the same way.

He sealed the only door with the duplicator, and from a small opening in the wall, he spoke to them.

"I'm leaving," he said. "You'll find everything in there to set up light housekeeping but food and heat. There'll be no heat, for I've removed the heating plant. You can see it through this hole, but the hole will soon be closed by the feeding machine, which I'm fixing so that you can eat when hungry. I'd prefer that you stay alive while you slowly freeze. Eventually your batteries will give out, and then—curtains.

"But I've got to leave because things are running my way and I've got to be in a place to cash in on it.

Keg Johnson greeted Don warmly. Then he said, "I knew you'd do it sooner or later," with a grin.

Don blinked. "The last time you said that was in the courtroom in Buffalo after we wrecked the economic system with the matter-duplicator. What is it this time?"

"According to the guys I've had investigating your coupled-crystal effect, it is quite simple. The effect will obtain with any crystalline substance—so long as they are absolutely identical! It took the duplicator to do it right to the atomic lattice structure. You'll get any royalties, Channing, but I'm getting all my ships talking from ship to ship direct, and from Canalopsis direct to any ship. You've just invented Venus Equilateral out of business!"

Don nodded. "Venus Equilateral is fun—and always has been. But, darn it, here we are out here in space lacking the free sky and the fresh natural air. We'd never abandon it so long as Venus Equilateral had a shred of necessity. But—now we can all go home to Man's Natural Environment. A natural planet."

"Furnish the Communications Stations at Northern Landing, at Canalopsis, and on Terra with coupled-crystal equipments. Then we abandon Venus Equilateral in one grand celebration."

"Nope. For one thing, they're honeymooning where no one knows. And so we'll just leave quietly and when they come back, they'll find that Venus Equilateral is a large empty house. Run off on us, will they!"

Don shook his head. "Why bother?" he asked. "People will know sooner or later, and besides, these days I'd prefer to keep the coupled-crystal idea secret as long as possible. We'll get more royalty, because once it is known, the duplicators will go crazy again. So long as Venus Equilateral—the generic term—maintains interplanetary communications, that's all that is necessary. Though Venus Equilateral as an identity is no more, the name of the interplanetary communications company shall be known as Venus Equilateral as a fond tribute to a happy memory of a fine place. And—"

Farrell noted the thermometers that measured the temperature of the cold room. "About all we'd have to do is to hold the door open and Venus Equilateral will have its first snow storm."

"Just like Mars," said Jim. "No wonder Christine eloped with Walt. Bet they're money-hooning on Venus."

"Well," said Channing, "turn up the gain on that ice-cream freezer of Walt's, and we'll have our winter snowstorm. A white Christmas, by all that's good and holy!"

Farrell grinned widely and reached up to the servo panel. He twisted the master control dial all the way clockwise and the indicators read high on their scales. Imperceptibly, the recording thermometers started to creep downward—though it would take a day or so before the drop became evident.

"Get everything in motion," said Channing. "Arden, make plans to clean out about an acre of former living space—make a one-room apartment out of it. Get the gals a-decorating like mad. Wes, get someone to make a firebrick and duplicate it into enough to build a fireplace. Then make enough fireplaces to go around to all as wants 'em. For draft, we'll tie the chimneys together and let it blow out into space at fourteen pounds per square inch of draft. Better get some good dampers, too. We'll have the air-duplicator running at full blast to keep up. We've got some crude logs—duplicate us a dozen cords of wood for fire-wood. Tell the shopkeepers down on the Mall that the lid is off and the Devil's out for breakfast! We'll want sleds, fur coats, holly and mistletoe by the acre. And to hell with the lucite icicles they hang from the corridor cornices. This year we have real ones.

"Oh," he added, "better make some small heating units for living rooms. We can freeze up the halls and 'outdoor' areas, but people want to come back into a warm room, shuck their earmuffs and overcoats and soak up a cup of Tom and Jerry. Let's go, gang. Prepare to abandon ship! And let's abandon ship with a party that will go down in history—and make every man, woman, and child on Venus Equilateral remember it to the end of their days!"

"Poor Walt," said Arden. "I wish he could be here. Let's hope he'll come back to us by Christmas."

For the ten thousandth time Walt inspected the little metal house. It was made of two courses of metal held together with an insulating connector, but these metal walls had been coupled with water now, and they were bitter cold to the touch.

Lights were furnished from outside somewhere, there was but a switch in the wall and a lamp in the ceiling. Walt thought that he might be able to raise some sort of electrical disturbance with the lighting plan, but found it impossible from the construction of the house. And, obviously Kingman had done the best he could to filter and isolate any electrical fixtures against radio interference that would tell the men in Venus Equilateral that funny-work was a-foot. Kingman's duplicator had been removed along with anything else that would give Walt a single item that he could view with technical eye.

Otherwise, it was a miniature model of a small three-room house; not much larger than a "playhouse" for a wealthy child, but completely equipped for living, since Kingman planned it that way and lived in it, needing nothing.

Christine shuddered. "What I'm wondering is when these batteries will run out," she said.

"Kingman has a horse-and-buggy mind," said Walt. "He can't understand that we'd use miniature beam-energy tubes. They won't give out for about a year."

"No, we damwel can't," grunted Franks unhappily. "These suits aren't designed for anything but a severe cold. Not a viciously killing kind. At best, they'll keep up fairly well at minus forty degrees, but below that they lose ground degree for degree."

"Don't let that get you," said Walt nervously. "That's the first sign of cold-adaptation."

"I know," she answered. "I've seen enough of it on Mars. You lose the feeling of cold eventually, and then you die."

Walt held his forehead in his hands. "I should have made an effort," he said in a hollow voice. "At least, if I'd started a ruckus, Kingman might have been baffled enough to let you run for it."

"Walt," she said quietly, "remember? Kingman had that gun pointed at me when you surrendered."

"Fine prospect. No one knows we're here; they think we're honeymooning. The place is chilling off rapidly and will really slide like hell once that room and the original tube reaches absolute zero. The gang below us don't really know what's going on because they left the refrigerator tube to my care—and Channing knows that I'd not go rambling off on a honeymoon without leaving instructions unless I was certain without doubt that the thing would run without trouble until I returned. I'm impulsive, but not forgetful. As for making any kind of racket in here—we're licked."

"Not a chance—at least nothing that I know I can do between the removal of the suit and the making of communications. They're just power intake tubes tuned to the big solar beam jobs that run the station. I—"

Christine put cold hands on his cheeks. "Walt, what would have happened if I'd not been along?"

"Walt, I would have. You couldn't have kept me. So, regardless of whether you blame yourself, you need not. If anybody is to blame, call it Kingman. And Walt, remember? I've just found you. Can you imagine—well, put yourself in my place—how would you feel if I'd walked out of your office and dropped out of sight? I'm going to say it once and only once because it sounds corny, Walt, but I'd rather be here and knowing than to be safe and forever wondering. And so long as there is the breath of life in us, I'll go on praying for help."

Walt put his arms around her and held her gently. Christine kissed him lightly. "Now I'm going to curl up on that couch," she said. "Don't dare let me sleep more than six hours."

"And I'll measure time for you. Once we start sleeping the clock around, we're goners."

Christine went to the couch and Walt piled the available covers on after he checked the operation of the power tube that furnished heat for her suit. He turned it up a bit, and then dimmed the light.

For Walt there was no sleep. He wandered from room to room in sheer frustration. Given anything of a partially technical nature and he could have made something of it. Given a tool or two or even a few items of kitchen cutlery and he might have quelled his restlessness in working toward some end. But to be imprisoned in a small house that was rapidly dropping toward zero degrees Kelvin without a book, without a knife or fork or loose bit of metal anywhere was frustration for the technical mind.

Mark Kingman, of course, had been quite afraid of just that and he had skinned the place bare of everything that could possibly be used. Kingman even feared a loose bit of metal because metal struck against metal can produce sparks that will light a fire.

And Walt knew that it would take only a few more days before that, too, would end.

For the metal of the house was getting to the point where he stuck to it if he touched it. The suits kept them warm—to take them off would have been sheer folly.

So from kitchenette to bathroom to livingroom prowled Walt. He swore at the neat little shower—the water was frozen, even had anybody wanted to take a bath.

Kingman entered the conference room of the Interplanetary Communications Commission with confidence. He knew his ground and he knew his rights, and it had been none other than Mark Kingman who managed to call this meeting together. With a bland smile, Kingman faced the members of the Commission.

"I wish to state that the establishment known as Venus Equilateral has forfeited their license," he said.

This was intended to be a bombshell, and it did create a goodly amount of surprise on the part of the Commission. The chairman, Lewis Hollister, shook his head in wonder. "I have this morning received a message from Mars."

"I'm not acquainted with the present celestial positions," said Hollister. "However, there are many periods during which time the communications are made direct from planet to planet—when Terra and Mars are on line-of-sight to Venus and one another."

"The celestial positions are such that relay through Venus Equilateral is necessary," said Kingman.

Kingman unrolled a chart showing the location of the planets of the inner solar system—Mars, Terra, Venus—and Venus Equilateral. According to the lines-of-sight drawn on the map, the use of the relay station was definitely desirable.

"The Research Services Corporation of Northern Landing, Venus, have for years been official monitors for the Interplanetary Communications Commission," explained Mark Kingman. "I happen to be a director of that corporation, which has research offices on Terra and Mars and is, of course, admirably fitted to serve as official monitor. I make this explanation because I feel it desirable to explain how I know about this. After all, an unofficial monitor is a lawbreaker for making use of confidential messages to enhance his own position. As an official monitor, I may observe and also make suggestions pertaining to the beat interests of interplanetary communications.

"It has been reported along official channels that the relaying of messages through the Venus Equilateral Relay Station ceased as of twelve hundred hours Terran mean time on Twenty December."

"They must," said Kingman. "Whether they use radio or the sub-electronic energy bands, they cannot drive a beam direct from Terra to Mars without coming too close to the sun. Ergo they must be relaying."

"Perhaps—and of course, the use of a secondary medium is undesirable. This matter of interrupted or uninterrupted service is not the major point, however. The major point is that their license to operate as a major monopoly under the Communications Act insists that one relayed message must pass through their station—Venus Equilateral—during every twenty-four hour period. This is a safety measure, to ensure that their equipment is always ready to run—even in periods when relaying is not necessary."

Kingman cleared his throat. "A number of times," he agreed. "But each time that discontinuance of service occurred, it was during a period of emergency—and in each instance this emergency was great enough to demand leniency. Most of the times an explanation was instantly forthcoming; the other times were after seeking and receiving permission to suspend operations during the emergency period. This, gentlemen, is Twenty-three December and no message has passed through the Venus Equilateral Relay Station since noon on Twenty December."

"Your statements, if true, indicate that Venus Equilateral has violated their license," nodded Hollister. "However, we are inclined to be lenient with them because they have been exemplary in the past and—"

"And," interrupted Kingman, "they are overconfident. They think that they are big enough and clever enough to do as they damn well please!"

"We've seen no reason for interfering with their operations. And they are getting the messages through."

Hollister shrugged. "If you claim they aren't using the station, I wouldn't know."

"Venus Equilateral has failed to live up to the letter of their license regardless of what medium they are using to relay communications around Sol," said Kingman. "Therefore I recommend that you suspend their license."

"As of three years ago, the Terran Electric Company of Evanston, Illinois, received an option on the operation of an interplanetary communications company," said Kingman. "This option was to operate at such a time as Venus Equilateral ceased operating. Now, since Venus Equilateral has failed, I suggest that we show them that their high-handedness will not be condoned. I recommend that this option be fulfilled; that the license now held by Venus Equilateral be suspended and turned over to Terran Electric."

Hollister nodded vaguely. "You understand that Venus Equilateral has posted as bond the holdings of their company. This of course will be forfeit if we choose to act. Now, Mr. Kingman, is the Terran Electric Company prepared to post a bond equivalent to the value of Venus Equilateral? Obviously we cannot wrest holdings from one company and turn them over to another company free of bond. We must have bond—assurance that Terran Electric will fulfill the letter of the license."

"Naturally we cannot post full bond," replied Kingman stiffly. "But we will post sufficient bond to make the transfer possible. The remainder of the evaluation will revert to the Commission—as it was previously. I might point out that had Venus Equilateral kept their inventiveness and efforts directed only at communications, they would not be now in this position. It was their side-interests that made their un-subsidized and free incorporation possible. I promise you that Terran Electric will never stoop to making a rubber-stamp group out of the Interplanetary Communications Commission."

Hollister thought for a moment. But instead of thinking of the ramifications of the deal, Hollister was remembering that in his home was a medium sized duplicator made by Terran Electric. It had a very low serial number and it had been delivered on consignment. It had been sent to him not as a gift, but as a customer-use research—to be paid for only if the customer were satisfied. Not only had Terran Electric been happy to accept the thousand dollar bill made in the duplicator, but it had happily returned three hundred dollars' worth of change—all with the same serial number. But since Hollister received his consignment along with the very first of such deliveries, Hollister had prospered very well and had been very neatly situated by the time that the desperate times of the Period of Duplication took place. Hollister recalled that Venus Equilateral wanted to suppress the duplicator. Hollister recalled also that Venus Equilateral had been rather rough on a certain magistrate in Buffalo, and though he thought that it was only a just treatment, it was nevertheless a deep and burning disrespect for the Law.

Besides, if this deal went through, Hollister would once more be a guiding hand in the operation of Venus Equilateral. He did believe that Channing and Franks could out-do Terran Electric any day in the week, but business is business. And if Kingman failed, the license could always be turned back to Channing & Co.—with himself still holding a large hunk of the pie.

"You will post bond by certified identium check," said Hollister. "And as the new holder of the license, we will tender you papers that will direct Venus Equilateral to hand over to you as representative of Terran Electric, the holdings necessary to operate the Venus Equilateral Relay Station and other outlying equipments and stations."

Kingman nodded happily. His bit of personal graft had begun to pay off—though he of course did not consider his gift anything but a matter of furnishing to a deserving person a gratuity that worked no hardship on the giver.

The bond annoyed Kingman. Even in an era when material holdings had little value, the posting of such securities as demanded left Kingman a poor man. Money, of course, was not wanted nor expected. What he handed over was a statement of the equivalent value on an identium check of the Terran Electric Company, his holdings in the Research Services Corporation, and just about everything he had in the way of items that could not be handled readily by the normal sized duplicator. At Terran Electric, for instance, they had duplicators that could build a complete spacecraft if done in sections, and these monstrous machines were what kept Terran Electric from the cobweb-growing stage. A man could not build a house with the average household-sized duplicator, and to own one large enough to build automobiles and the like was foolish for they were not needed that often. Kingman didn't like to post that size of bond, but he felt certain that within a year he would be able to re-establish his free holdings in Terran Electric because of revenues from Venus Equilateral. Doubtless, too, there were many people on Venus Equilateral that he could hire—that he would need desperately.

A duplicator produced snowflakes by the myriad and hurled them into the corridor-ventilators. They swirled and skirled and piled into deep drifts at the corners and in cul-de-sacs along the way. A faint odor of pine needles went with the air, and from newly-installed water pipes along the cornices, long icicles were forming. There was the faint sound of sleigh bells along the corridors, but this was obviously synthetic since Venus Equilateral had little use for a horse.

Kids who had never seen snow nor known a cold snap reveled in their new snow suits and built a huge snowman along the Mall. One long ramp that led into a snaky corridor was taken over by squatter's or rather "sledder's"—rights and it became downright dangerous for a pedestrian to try to keep his ankles away from the speeding sleds.

Snow forts were erected on either side of one wide corridor and the air was filled with flying snowballs.

And from the station-wide public announcement system came the crooned strains of Adeste Fideles and White Christmas.

A snowball hissed past Arden's ear and she turned abruptly to give argument. She was met by another that caught her full in the face—after which it was wiped off by her husband. "Merry Christmas," he chuckled.

"Not very," she said, but she could not help but smile back at him. When he finished wiping her face Arden neatly dropped a handful of snow down his collar. He retaliated by scooping a huge block out of a near-by drift and letting it drape over her head. Arden pushed him backwards into a snowbank and leaped on him and shovelled snow with both hands until her hands stung with cold and Don was completely covered.

Channing climbed out of the drift as Arden raced away. He gave chase, though both of them were laughing too much to do much running. He caught her a few hundred feet down the hall and tackled her, bringing her down in another drift. As he was piling snow on her, he became the focal point of a veritable barrage from behind, which drove him to cover behind a girder. His assailants deployed and flushed him from behind his cover, and he stood in the center of a large square area being pelted from all sides.

Channing found a handkerchief and waved it as surrender. The pelting slowed a bit, and Channing took that time to race to one side; join Jim Baler, and hurl some snowballs at Barney Carroll across the square. That evened things and the snowfight was joined by Arden, who arose from her snowdrift to join Barney Carroll and Keg Johnson.

Then down the corridor there hurtled a snowball a good two feet in diameter. It caught Channing between the shoulder blades and flattened him completely. Baler turned just in time to stop another one with the pit of his stomach. He went 'ooof!' and landed in the drift beside Don. Another huge one went over their heads as Don was arising, and he saw it splat against a wall to shower Barney Carroll and Arden with bits.

"Those would," remarked Don. "And if Walt weren't honeymooning somewheres, I'd suspect that Our Tom Swift had just hauled off and re-invented the ancient Roman catapult."

"There's always Wes Farrell, or does the physicist in him make him eschew such anachronisms?" asked Jim.

Arden scurried across the square in time to hear him, and she replied: "Not at all. So long as the thing is powered by a new spring-alloy and charged by a servo-mechanism run by a beam-energy tube. Bet he packs 'em with an automatic packing gadget, too."

Barney Carroll caught one across the knees that tripped him headlong as he crossed the square. He arrived grunting and grinning. "We can either take it idly," he said, "or retreat in disorder, or storm whatever ramparts he has back there."

"I dislike to retreat in disorder," said Channing. "Seems to me that we can get under that siege-gun of his. He must take time to re-load. Keep low, fellers, and pack yourself a goodly load of snowballs as we go."

Don stripped off his muffler, and made a sling of it. Then down the corridor they went, dodging the huge snowballs that came flying over at regular intervals. Channing finally timed the interval, and then they raced forward in clear periods and took cover when fire was expected.

They came upon Farrell eventually. He was 'dug in' behind a huge drift over which the big missiles came looping. Farrell had obviously cut the power of his catapult to take care of the short-range trajectory, but his aim was still excellent. With as many snowballs as they could carry, the attackers stormed the drift, pelting without aim until their supply was gone and then scooping snow up and throwing without much packing.

Behind the rampart was Wes Farrell with a trough-shaped gadget and a pair of heavy coil springs. Above the rear end of the trough was a duplicator. It dropped a snowball on the trough and the springs snapped forward.

The flying ball caught Don Channing in the pit of the stomach just as he attained the top of the rampart.

When he regained the top once more, the festivities were about over. The shooting was stopped, and the others of his side had Farrell held face upward on the trough while the duplicator dropped snowball after snowball on him.

Farrell did not think that funny. He struggled to his feet and then grinned, "Fine war," he told them. "Anybody ready for a bit of hot toddy?"

Channing grunted. "Yeah, and a hot bath and a hearty dinner and a seven hour sleep. So you've taken over Walt's job of making weapons, huh?"

Don sobered. "He's missing plenty. I've got all the word out that if he's seen, get here quick. He must have dropped the Relay Girl in some out of the way place. He hasn't landed on any regular spaceport."

"We've got likker and wassail and turkey," said Arden. "Also mistletoe. Let's go to our place and drink Walt's health and Christine's happiness."

"And that's appropriately apportioned," remarked Don with a grin. "Walt's health and Christine's happiness. But I'll bet a hat that they'd not mind being cold if they knew what fun this is." He brushed snow from the back of his neck and grinned. "Let's add fuel for the inner man," he suggested, leading the way to the Channing apartment.

Walt Franks sat dully in a chair, his eyes glazed over and but half open. Through them dimly and out of focus he could see Christine, who was huddled and quiet under the blankets. Her lips were blue and Walt felt dully that this should not be so but he had trouble remembering why. There was but one thought in his mind, and that was to awaken Christine before he himself fell asleep. They'd been doing that for—for—for years? No, that was not right. It must have been days, because he hadn't been living with Christine for years. Fact, he hadn't really lived with Christine at all; he'd just found her when this all happened—and—and—

He shook himself, and the motion hurt inside and outside. His muscles ached and where his skin touched a bit of clothing that hadn't been against his skin before it was bitterly cold. Quickly, Walt opened his hands and then drew out his left hand from the pocket and took a quick look at his wrist watch. He stuffed his hand back in again quickly and tried to stand up.

His legs were numb and he almost fell forward, which carried him where he wanted to go anyway, so he just let himself stumble forward heartlessly until he fell on his knees beside the couch.

"Christine," he mumbled. To himself his voice sounded loud, but it was faint and cracked. It hurt his lips to move, but he moved them for Christine where he would have moved them for no one else.

Walt stood up and made his way to the accursed feeding machine. He pressed the button and collected dollops of hot food in a shallow bowl. It was a mess because coffee mingled with the many other items of a fine balanced diet including appetizer and dessert made just that—a mess. But it was hot and it was food, and though there was not a single bit of silverware in the place, Walt managed. He carried the bowl to the couch and offered it to Christine, who protestingly permitted Walt to feed her with his fingers. She did not eat much, but it did warm her. Then Walt finished the plate.

Christine thought that over for a full minute. Then she said: "Must get up, Walt."

Walt wanted to let her stay there, but he knew that she must arise and move in order to keep from freezing. He nodded dumbly.

"Losing ground," he said, meaning the heated suite. Minutes he considered it. Long minutes....

There was a faint crackling noise, and a pungent odor came. It increased without either of them noticing it because their senses were numbed. A curl of smoke wreathed Walt's chest and it rose above his face and got into his eyes. Walt coughed and tears came and the salty water dribbled down his cheeks, dropped to his suit, and froze.

Walt looked down at his hip, where the tiny power tube was, and he saw it smoking. As he watched, flame burst from the inside and came through.

He shucked the suit just as it burst into open flames, and he watched it burn on the metal floor. He warmed himself against the flames, but they were too meager to really help, and five minutes later all that was left of the heated suit was a still-operating power tube and a tangled maze of red hot heater-resistance wire.

Walt shivered. Beneath the suit he wore the usual slacks and short-sleeved shirt, and it was pitifully inadequate. The dullness that had been assailing him for hours reasserted itself—strengthened by the exertion of removing the suit—and helped not at all by the scant warmth from the fire.

Walt reeled dizzily, his eyes half closed, beads of ice from the tears on his lashes gave the scene a dazzlingly sparkling tone that prevented him from seeing clearly.

He fell forward and his body twitched violently as his skin touched the viciously cold metal of the floor.

Christine hurled the covers back and with great effort she pulled and lifted Walt onto the couch. She covered him and then leaned down and kissed him with dry, cracked lips. As she stood up, she felt a spear of pain at her side.

Looking, she found her suit on fire as Walt's had been. As Christine fumbled with cold fingers at the fastenings, she realized that only the added warmth of the blankets had kept both suits from burning out at the same time. For they were duplicated models and were identical; therefore they would burn out at exactly the same temperature.

She shivered in her thin summer frock even though she stood with the flames licking at her sandals.

Then there were two useless tangles of wire on the floor, their red-hot wires struggling hopelessly against the monstrous quantity of cold.

Christine shuddered convulsively, and turned slowly to look at Walt. He was asleep already.

Christine's eyes filled with tears which she brushed away quickly. She smiled faintly.

It seemed warmer under the blankets, or maybe it was warmer there beside him. His arm went around her instinctively though he slept and Christine pressed against him partly to gain what warmth there was from him and partly to give him what warmth there was in her.

Or, she thought just before the dizzying but welcome waves of black slumber crept over her, this is that feeling of warmth that goes before—

"Now that," said Arden with complimentary tones, "is something that duplicating can't buy."

She meant the twenty piece orchestra that filled the vast hall with music. It was a vast place, for it contained three thousand people, all talking or dancing. Joe presided over a bowl of punch that would have made Nero die of jealousy—it was platinum, fifteen feet in diameter and studded profusely with huge gold chasings and inlays, and positively alive with diamonds and emeralds. On the edge of the huge bowl hung Joe's original sign, and Joe handled a huge silver ladle to scoop the highly-charged punch into small gold cups.

Linna Johnson, she of the formerly be-jewelled class, proudly displayed a bit of hand-made jewelry and told everybody that Keg had made it for her. Barney Carroll was holding forth at great length to a group of women on the marvels and mysteries of digging in the Martian desert for traces of the Lost Martian Civilization, while his partner Jim was explaining to Chuck and Freddie Thomas just how they intended to let a matter-transmitter do their excavating for them. Wes Farrell was explaining the operation of the element-filter and heterodyne gadget that produced pure synthetic elements to a woman who nodded gayly and didn't understand a word he said but would rather be baffled by Farrell than be catered to by anyone else.

"It's an occasion to remember," grinned Don. "Christmas Eve at Venus Equilateral! Here's Triplanet Films with their cameramen, and they tell me that the Interplanetary Network has called off all Christmas broadcasts at midnight, Terra mean time, to carry the sounds of revelry from Venus Equilateral as a Christmas celebration program."

"Yeah," said Arden, "and tomorrow I've got to go to church and explain to a class of Sunday Schoolsters how and why Santa Claus can make the haul across a hundred million miles of space in an open sleigh powered with a batch of reindeer."

Hilda Warren smiled happily. "I don't think I've ever appreciated how many people really worked here," she said.

"Shucks," grinned Don, "I've been trying to get along by merely mumbling about half of the names myself. And if I may point it out, Hilda, you're standing under a hunk of mistletoe." And before she could say anything, Don had proceeded with great gusto to the amusement of Warren.

Arden shook her head. "The rascal has been standing there for a half hour because people are always coming up to tell him it's a fine party."

There was a faint tinkle of bells in the distance, and as people became aware of them, Keg Johnson tapped Don on the shoulder and said: "The fleet's in, Don. Here comes our professional Santa Claus. And the fleet is going to land and await midnight tomorrow night. The Johnson Spaceline is going to have the honor of hauling, bag, baggage, foot, horse, and marines to Terra. Everything ready?"

Don nodded absently. He listened to the sleigh bells for a moment and then said: "Everything of a personal nature is packed. The rest is worthless. How many men have you?"

"Then tell 'em to forget the packing and join in. After this mass, we won't even notice a couple of hundred more. But tell me is S. Claus going to drive that thing right in here?"

Keg nodded. "He's running on snow in the corridor, of course, but he's equipped with wheels for hard sledding."

The orchestra broke into Jingle Bells and a full dozen reindeer came prancing in through the large double doors. They came in a whirl of snow and a blast of icy air from the corridor, and they drew a very traditional Santa Claus behind them in the traditional sleigh laden with great bags.

Before the door was closed on the veritable blizzard in the hallway, several men came in hauling a great log which they placed on the monstrous fireplace at one end of the vast hall.

The only incongruity was the huge spit turned by a gear train from a motor run from a beam energy tube.

Santa Claus handed out a few gifts to those nearest and then mounted the orchestra platform. He held up his hands for silence.

"Before I perform my usual job of delivering gifts and remembrances," he said, "I want you to hear a word or two from your friend and mine—Don Channing!"

"My friends," said Don Channing, "I've very little to say and I'm not going to take a lot of time in saying it. We've had a lot of hard work on Venus Equilateral and we've had a lot of fun. Venus Equilateral has been our home—and leaving our home tomorrow night will be as great a wrench as was the leaving of our original homes so many years ago to come to Venus Equilateral. It will for me. I shall darned well be homesick.

"Yet—this job is finished. And well done. Frankly," he grinned cheerfully, "we started out just covering the planet-to-planet job. We extended that to include planet-to-ship, and then when they added ship-to-planet, it automatically made it ship-to-ship. Well, we've got it all set now to make it anywhere-at-all without relay. People speak of Venus Equilateral and forget the Relay Station part of the name. A relay station is no darned good without something to relay—and you know, good people, I'm completely baffled as of now for a communications project. I can't conceive of a problem in communications that would be at all urgent. I—"

A loop of the maze of heater-wire from the fire-ruined suit twisted on the bare metal floor. The bare metal shorted part of the long loop and the remaining section grew hotter as a consequence. The expansion caused by heat made the tangle of wire writhe slowly, and two crossing lines touched, shortening the overheated loop still more.

It flared incandescent and blew like a fuse and showered the room with minute droplets of molten metal that landed on wall and floor solid, but yet warm.

A tiny stinging rain of them pelted Walt's face. This penetrated when few other things would have. Walt stirred coldly painful, and his eyes struggled against a slightly-frozen rim that tried to hold eyelash to cheek.

He could not know that it had been his subconscious mind. To the trained electronic technician the arc-discharge of a shorted circuit has a special meaning where to the untrained it may be but an ambiguous "Splat!" The blowing of a fuse penetrates the subconscious and brings to that part of the brain a realization of the facts in the case just as a trained musician will wince when the third violin strikes a sour note in the midst of full orchestration.

Instinctively, Walt's trained brain considered the source. Ponderously slow, he turned painful head to look on the floor at the remains of the ruined suits. As he watched, the still writhing metal shorted again and a loop glowed brightly, then died as the additional heat expanded it away from its short circuit.

He found his left arm trapped beneath Christine and he turned from one side to the other and he considered her dully. She slept, and was as still and stiff as death itself.

Walt released his arm, and the motion beneath the blankets pumped viciously cold air under the covers and chilled his already stiff body. He looked at his watch; it was nine hours since he'd awakened Christine before.

Walt felt no pain, really. He wanted desperately to snuggle down under the covers once more and return to oblivion, where it was warmer and pleasant. But there was something—

Taking his nerve in his teeth, Walt forced his brain to clear. Christine—didn't deserve this.

Yet if he got out from beneath those covers he would most certainly freeze in a matter of minutes. Yet he must—do—something.

He considered the tubes and their tangles of wire through puffed, half-closed eyes. He thought he was moving with lightning-rapidity when he leaped out of the bed but his motion was insufferably slow. He dropped on his knees beside the tubes and with his bare hands he fumbled for the hot wires. They seared his fingers and sent pungent curls of smoke up to torture his nose, but his fingers felt no pain and his olfactory sense did not register the nauseous odor of burning flesh.

He collected loop after loop and shorted them close to the terminals of the two tubes. A hundred feet of wire looped back and forth in a one-inch span across the terminal lugs would produce a mighty overload. It made a bulky bundle of wire the very mass of which would prevent it from heating to incandescence and blowing out in a shower of droplets.

For to the trained technician, a blown fuse is not an ill. It is a symptom of an ill, and no trained technician ever replaced a blown fuse without attempting to find out why and where the overload occurred.

Walt crept painfully back to bed and huddled under the blankets against Christine.

"—there is but one unhappy note in this scene of revelry," continued Don Channing a bit soberly. "We're sorry that Walt Franks took this opportunity of rushing off to get matrimonially involved with Christine Baler. He didn't know this was imminent, of course, otherwise he'd have been here. We all love Walt and he'll be unhappy that he missed the blowout here. Fact is, fellers, I'd give eight years off of the end of my life to get any kind of word from Walt—"

An alarm clamored in the hallway and Wes Farrell jumped a foot. He headed for the door, but Channing stopped him with a gesture.

"Friend Farrell forgets that we no longer care," laughed Channing. "That was the main fuse in the solar-energy tubes blowing out and we won't be needing them any more. It is sort of pleasant to know that a fuse blew—a thing that was formerly master and we the slave—and that we don't have to give a hoot whether it blew or not. Let it blow, Wes. We don't need power any more!

"So I suggest that we all have a quick one on Walt Franks wishing him health and happiness for the rest of his life with Christine nee Baler, even though the big bum did cheat us out of the privilege of kissing his bride.

There was a thunderous roar of applause, and Channing rejoined Arden and the rest of them, who had sort of gravitated together.

Keg Johnson nodded. "Merry Christmas—and on to Terra for your Happy New Year!"

They raised their glasses, and it was Wes Farrell who said: "To Walt—and may he be as happy as we are!"

Arden chuckled. "We used to sing a song about 'Walt's Faults' but there's one thing, Walt would have replaced that fuse even though we didn't need it. The old string-saver!"

A messenger came up and tapped Don on the shoulder. Channing turned with an apologetic smile to his guests and said: "I get more damned interruptions. They tell me that someone is knocking on the spacelock door. If anyone here knows any prayers, let 'em make with a short one. Pray this—whoever it is—knows something about Walt."

Don left the party and went along the cold, snow-filled corridor to his office. As one of the few remaining places where operations were in full tilt, Channing's office was where any visitor would be conducted. Once the business was finished, Channing could hurl the guest into the middle of the big party, but the party was no place to try to conduct business in the first place.

So with heels on desk, a glass of Scotch from his favorite file drawer, Don Channing idled and waited for the visitor.

Two policemen—The Terran Police—entered quietly and stood aside as the third man entered cautiously.

"The spectre at the feast," snorted Channing. "Of all the people I know, I least expected you—and wanted to see you least. I hope it is a mutual affection, Kingman."

"Don't be godlike, Channing," said Kingman coldly. "You may think you're running things all your way, but some people object to being made a rubber stamp."

"Look, Kingman, get whatever is on that little mind of yours damn well off it so I can continue as I was."

"Venus Equilateral suspended operations on Twenty December," said Kingman. "Without notice nor permission nor explanation. Since the relay-beams of Venus Equilateral have carried nothing for a period beyond that permitted for suspension of operations by the Interplanetary Communications Commission, they have seen fit to revoke your license."

"You see—you think you can get away with anything. Doubtless this ultra-frigid condition was the cause of failure?"

"Don't be flippant. You'll find that these papers are final and complete. You'll not be able to talk your way out of it."

"Tell me, O Learned Legal Light, who is going to run Venus Equilateral when I am far away?"

"Some time ago Terran Electric applied for a franchise and took an option pending failure at Venus Equilateral. This failure has taken place and Terran Electric now controls—

"I gather that you've been forced to put Terran Electric up as bail for the license?"

"Did it ever occur to you that maybe Venus Equilateral wasn't worth much either?" asked Channing.

"I'll make it work for me. And I'll also report that one of your wild experiments got loose and nearly froze the station out completely. I still say that if you'd stopped toying around with everything that came along, Venus Equilateral would still be a running corporation."

"I daresay you're right. But the devil finds work for idle hands, you know. So just what is the future holding?"

"Channing, your attitude is entirely frivolous and unconvinced that I mean business. To convince you, I'm going to give you twelve hours to relinquish the station and be on your way from here!"

"I've investigated that," returned Kingman. "I find that Christmas is a completely Terran date and is therefore legal for any and all legal action on any planet or place removed from the interplanetary boundary of the planet Terra. That, Channing, has been established to be the Channing Layer."

"And how about the personnel? Must they get the hell off too?" asked Channing loftily.

"You and your managerial cohorts must leave. Those upon whom the continued service of communications depend are requested to remain—under new management."

"Good. And now that you've had your say I'll return to my own affairs. Make yourself at home; you'll not be bothered here."

Kingman nodded slowly. He'd expected a battle, and he believed that Channing did not think it true. Channing would find damn well out once he appeared before the Interplanetary Communications Commission.

In the meantime, of course, he might as well remain in the office. There was an apartment next door, and it was comfortable.

He did not notice that every very personal thing had been removed from Channing's office. Frankly, Kingman did not care. He had everything his own way.

Channing went back to the party and spent ten minutes telling his friends what had happened. Then he forgot about it and joined in the merrymaking, which was growing more boisterous and uninhibited by the moment. It was in the wee small hours of the clock—though not necessarily the night, for there is no such thing on Venus Equilateral—when the party broke up and people bundled up and braved the howling blizzard that raged up and down the halls.

Arden sat up in bed and looked sleepily around the dark bedroom. "Don," she asked with some concern, "you're not sick?"

Arden pursed her lips. She snapped the light on and saw that Don was half-dressed.

"Those tubes have been running on a maintenance load for days. They shouldn't blow out."

Arden smiled as she continued to climb into her clothing. "You're not the only one in this family that has a lump of curiosity," she told him.

"Don," said his wife seriously, "rules is rules and electricity and energy are things I'm none too clear on. But I do know my husband. And when he gets up out of a warm bed in the middle of the night to go roaming through a frozen world, it's urgent. And since the man in question has been married to me for a number of years, getting up out of a warm bed and going out into snow and ice means that the urgency-angle is directed at whatever lies at the other end. I want to go see—and I'm going to!"

Channing blinked when he saw the light in the room where the solar intake tubes were. He hastened forward to find Wes Farrell making some complex measurements and juggling a large page of equations. Farrell looked up and grinned sheepishly.

Arden said: "Don't kid anybody. Both of you want to know why a fuse should blow on a dead line."

Farrell grinned and Channing nodded again. "I—" started Channing, but turned as the door opened.

"Thought we'd find you here," said Barney Carroll. Jim Baler added: "We got to arguing as to how and why a fuse should blow on an empty line and decided to ask you."

Arden squinted at Jim. "Did it ever occur to you that we might have been in bed?"

Barney grinned. "I figured if we were awake from wondering about it, so would you-all. So—"

Channing shook his head. "Ask Wes," he said. "He got here first and was measuring the deflecting electrode voltages when I arrived. I note that he has a hunk of copper busbar across the main fuse terminals."

Farrell handed the figures to Don. "That's where the short circuit load is coming from," he said.

"Up there," said Channing, "I'll bet it is hitting close to seventy or eighty degrees below zero. A supercold condition—"

He paused and shook his head. "The tube room reached absolute zero some time ago," he said, "and there's no heavy drain to that position."

"Well?" demanded Arden, yawning. "Do we wait until tomorrow morning or go up there now?"

Channing thought for a moment. "We're due to leave in the morning," he said. "Yet I think that the question of why anything up in an empty section of Venus Equilateral should be blowing fuses would belabor us all of our lives if we didn't make this last screwball search. Let's go. Wes, get your portable sun-finder, huh?"

"Figger of speech, sweet. We mean a small portable relay tube that we can stick in series with this gawd-awful drain and use for a direction finder. I have no intention of trying to scour every storeroom in that area for that which I don't really believe is there."

The main deterrent to swift action was the bitter, bitter cold that stabbed at their faces and hands which were not enclosed in the electrically heated suite—of which each one of them wore three against this ultraviolent chill.

"There should be a door here," objected Don, reading a blueprint from the large roll he carried under his arm. "Fact is, this series of rooms seems to have been sealed off entirely though the blueprint calls for a door, about here!"

"We break in," said Channing harshly. "Come on, gang. We're going back downstairs and get us a cutter!"

The cutter consisted of a single-focus scanner beam that Don wielded like an acetylene torch. Clean and silently it cut through the metal wall and the section fell inward with a slight crash.

"Someone has been homesteading," said Channing in a gritty voice. "Nice prefab home, hey? Let's add house-breaking to our other crimes. I'd like to singe the heels offa the character that did this. And I think I'll let the main one simmer."

Channing pointed to the huge energy tube at one end of the room. It bore the imprint of Terran Electric.

He applied his cutter to the wall of the cottage and burned his way through. "No one living here," he said. "Colder than Pluto in here, too. Look, Wes, here's your short circuit. Tubes from—"

Channing came over to stand beside Farrell, looking down at the too-still forms. Baler looked at Channing with a puzzled glance, and Channing shook his head quietly. Then he said: "I may be wrong, but it strikes me that Walt and Christine interrupted skullduggery at work and were trapped as a consequence. No man, no matter how insane, would ever enter a trap like this willingly. This is neither a love nest nor a honeymoon cottage, Jim. This is a death trap!"

Channing turned from the place and left on a dead run. He paused at the door to the huge room and yelled: "Don't touch 'em 'till I get Doc!"

By the clock, Christmas Day dawned bright and clear. The strip fluorescents came on in the corridors of Venus Equilateral and there began the inexorable flow of people towards the South End Landing Stage.

Each carried a small bag. In this were the several uniques he possessed and a complete set of recordings on the rest of his personal possessions. Moving was as easy as that—and once they reached Terra, everything they owned could be reproduced at will.

It was both glad and sad; the thrill of a new experience to come balancing the loss of the comfortable routine of the old. Friends, however, managed to get aboard the same spacecraft as a general rule and so the pain of parting was spared them.

One by one the huge ships dropped South and then headed for Terra. One by one until the three thousand-odd people who lived, loved, and operated Venus Equilateral through its working years had embarked.

Channing shook hands with Captain Johannson as he got aboard the last remaining ship. Behind Channing there came Keg Johnson, who supervised the carrying aboard of Walt Franks and Christine Baler. They were seated side by side in deck chairs on the operating bridge of the spacecraft and Arden came up to stand beside her husband as she asked: "Captain Johannson, you are empowered to perform matrimony?"

"Well," she said, "I'm the Maid of Honor and this husband of mine intends to be best man. We agree that the couple there have spent too much time living with one another—"

Christine reached over and took his hand. "She doesn't dare," said the girl. "She knows it was ah—er—colder than sin!"

Big Jim Baler clenched and unclenched his hands. "I still think we should have called on Mark Kingman," he said in a growl.

Channing shook his head. "And spoil the fine end of a fine holiday? Nope. And also spoil a fine bit of retribution?"

Linna Johnson smiled. "A man of action like Jim finds the finer points of retribution a bit too smooth," she said. "But it'll be plenty rough on Kingman."

"To the devil with Kingman," said Barney Carroll. "I say we ought to commit this ceremony at once and then repair to the bar—or have the bar repair here—and have a last drink to Venus Equilateral."

Walt Franks stood up. "I'm still stiff," he said. "But I'll be damned if I'm going to sit down at my own wedding."

Christine stood beside him. "You're thinking about that 'repair to the bar' and don't want to get left," she told him. "Well, frozen solid or not, I'm sticking tight."

Johannson turned to the pilot and gave the order. The big ship dropped from the platform, and they all looked down through the glass dome at the diminishing view of Venus Equilateral.

The captain turned to Channing and asked: "Just what did happen to Mark Kingman?"

"Mark has mortgaged his everlasting black soul to the hilt to maintain communications under the standard franchise. For a period of five years, Mark Kingman must live on that damned station alone in the cold and the loneliness, maintaining once each day a relay contact or lose his shirt. And because he dropped the Relay Girl into the sun when he planned that 'elopement' we've just confiscated his ship. That leaves Kingman aboard a practically frozen relay station with neither the means to get away nor the ability to handle the situation at all. He must stay, because when he puts a foot on any planet we clap him in jail for kidnaping. He's lost his financial shirt because Venus Equilateral is an obsolete commodity and he'll never regain enough of his personal financial standing to fight such a case.

Channing shook his head, leaving the sentence unfinished. He turned to Walt. "Got a ring handy?"

Wes Farrell held up a greenish metal ring that glinted iridescent colors. "Y'might try this new synthetic," he offered.

Walt shook his head. He fumbled in an inner pocket and came up with a small band that was very plain. "This is a certified unique," he said proudly. "It was mother's, and grandmother's, too."

Then with Venus Equilateral still visible in the port below and a whole sky above, Captain Johannson opened his book and started to read. Behind them was work and fun and pain, and before them—

Updated editions will replace the previous one—the old editions will be renamed.

Section 2. Information about the Mission of Project Gutenberg™

Project Gutenberg™ is synonymous with the free distribution of electronic works in formats readable by the widest variety of computers including obsolete, old, middle-aged and new computers. It exists because of the efforts of hundreds of volunteers and donations from people in all walks of life.

Volunteers and financial support to provide volunteers with the assistance they need are critical to reaching Project Gutenberg™’s goals and ensuring that the Project Gutenberg™ collection will remain freely available for generations to come. In 2001, the Project Gutenberg Literary Archive Foundation was created to provide a secure and permanent future for Project Gutenberg™ and future generations. To learn more about the Project Gutenberg Literary Archive Foundation and how your efforts and donations can help, see Sections 3 and 4 and the Foundation information page at www.gutenberg.org.

Section 3. Information about the Project Gutenberg Literary Archive Foundation

The Project Gutenberg Literary Archive Foundation is a non-profit 501(c)(3) educational corporation organized under the laws of the state of Mississippi and granted tax exempt status by the Internal Revenue Service. The Foundation’s EIN or federal tax identification number is 64-6221541. Contributions to the Project Gutenberg Literary Archive Foundation are tax deductible to the full extent permitted by U.S. federal laws and your state’s laws.

The Foundation’s business office is located at 809 North 1500 West, Salt Lake City, UT 84116, (801) 596-1887. Email contact links and up to date contact information can be found at the Foundation’s website and official page at www.gutenberg.org/contact

Section 4. Information about Donations to the Project Gutenberg Literary Archive Foundation

Project Gutenberg™ depends upon and cannot survive without widespread public support and donations to carry out its mission of increasing the number of public domain and licensed works that can be freely distributed in machine-readable form accessible by the widest array of equipment including outdated equipment. Many small donations ($1 to $5,000) are particularly important to maintaining tax exempt status with the IRS.

The Foundation is committed to complying with the laws regulating charities and charitable donations in all 50 states of the United States. Compliance requirements are not uniform and it takes a considerable effort, much paperwork and many fees to meet and keep up with these requirements. We do not solicit donations in locations where we have not received written confirmation of compliance. To SEND DONATIONS or determine the status of compliance for any particular state visit www.gutenberg.org/donate.

While we cannot and do not solicit contributions from states where we have not met the solicitation requirements, we know of no prohibition against accepting unsolicited donations from donors in such states who approach us with offers to donate.

International donations are gratefully accepted, but we cannot make any statements concerning tax treatment of donations received from outside the United States. U.S. laws alone swamp our small staff.

Please check the Project Gutenberg web pages for current donation methods and addresses. Donations are accepted in a number of other ways including checks, online payments and credit card donations. To donate, please visit: www.gutenberg.org/donate

Section 5. General Information About Project Gutenberg™ electronic works

Professor Michael S. Hart was the originator of the Project Gutenberg™ concept of a library of electronic works that could be freely shared with anyone. For forty years, he produced and distributed Project Gutenberg™ eBooks with only a loose network of volunteer support.

Project Gutenberg™ eBooks are often created from several printed editions, all of which are confirmed as not protected by copyright in the U.S. unless a copyright notice is included. Thus, we do not necessarily keep eBooks in compliance with any particular paper edition.

Most people start at our website which has the main PG search facility: www.gutenberg.org.

This website includes information about Project Gutenberg™, including how to make donations to the Project Gutenberg Literary Archive Foundation, how to help produce our new eBooks, and how to subscribe to our email newsletter to hear about new eBooks.
