                               SPECIMEN

                         BY CHARLES V. DE VET

                _The Zades had their sample Earthling.
                  What would eventually happen to the
                whole depended on what happened to the
                 specimen. It was as simple as that!_

As official reporter on the project I was in Srtes' office when they
brought the alien in. He was as tall as an average Zade, of pretty
much the same color, and would have been able to pass as one of us
except that he had no vestigial wings. It gave his shoulders an odd,
flat, appearance, and somehow added to the abrupt awkwardness of every
movement of his body. He might have had wires rather than muscles
beneath his soft dark skin.

There were other, minor differences, of course. Hair grew not only on
his head, but also on his body. Coarse, black hair. It could be seen
on his hands and the exposed portions of his arms, and on his chest
where his blouse was open at the neck. His eyes were brown and set wide
apart, with long hairs on the lid edges. His nose had no hard upper
ridge. The bone was covered only by the same flesh as the rest of his
face.

He was accompanied by a Commander Leik, captain of the space ship that
had brought him from Earth. When they entered Srtes rose and set the
scroll he had been studying to one side. "I welcome you back," he said
to Leik, touching his cheek with the greeting finger of his left hand.

Leik respectfully returned the gesture. "I am once more content," he
replied.

"Has he been instructed in our language?" Srtes asked, after the brief
formalities were over. He indicated the Earth native.

"He has become quite adept during the eight great tides since we left
his world," the Commander answered.

"It is well." Srtes turned and eyed the Earth man searchingly.

The alien returned the gaze, not defiantly, yet not at all
subserviently. I could tell that he was ill at ease. A fine sprinkling
of perspiration dotted his forehead, and he breathed slowly and deeply,
as though carefully timing each inhalation and exhalation.

"Do you have a name?" Srtes asked him.

He made a nodding motion with his head. "John Wilson," he said. The
words were clear enough, but spoken with a slurred, soft-palate, sound.

"You have two names?" The hairlines above Srtes' eyes raised slightly.

"It is the custom on their world," Leik supplied. "The surname has a
clan connotation."

"You understand your purpose here?" Srtes asked the outworlder.

"Yes." He added nothing to the reply.

"You are aware that there are no restrictions on the study we may make
of you?"

"Yes."

"Even that we may dissect you, or kill you, if we so desire?"

The alien's complexion changed subtly, becoming slightly lighter, and
his lips pressed firmly together. He made the bobbing motion with his
head again.

"His nodding signifies an affirmative reply," Leik interjected.
"He volunteered to come with us, so he is quite familiar with the
conditions."

"Volunteered?"

"It is strange," Leik agreed. "Yet when I offered to leave one of
our men in return for a specimen of their race--so that mutual study
might be made--I was firmly refused. It seems their culture has some
absurd belief in inherent rights of its individual members. I was saved
the inconvenience of abducting the necessary specimen when this one
volunteered."

Srtes had difficulty grasping the concept. His forehead creased in
concentration for a moment before he said, "Perhaps it would be better
if I read the report first. In the meantime, please escort him to
our physiologists on the ground floor. They can begin their study
immediately."

       *       *       *       *       *

For seventeen days they examined the alien. As expected, they learned
quickly that his body was intrinsically weak. His vital organs had no
protective walls of cartilage, and he was extremely vulnerable to the
thrust of any sharp or pointed weapon.

Our first opinion was that he would prove an innocuous foe. However,
as the tests continued, we began to have some doubts. Physically he was
quite powerful. His reflexes were sharp, and he showed an aptness at
learning that surprised us. And his intelligence was above average.

The twentieth day I was ordered to report to Srtes' office. I found the
other seven members of the council already conferring with Srtes when I
entered.

"We have been unable to arrive at any definite conclusion thus far,"
Srtes was saying. "Therefore it becomes necessary to try him in the
Big Run." He paused and frowned in annoyance as I made some slight
disturbance. Hurriedly I took my place. I moved among these men only by
sufferance.

"One of the crewmen on the space ship that brought him here," Srtes
resumed, "a Zade named Ctvar, clashed with the alien several times
during the voyage. He was restrained from violence by the captain. This
Ctvar should prove an apt instrument for driving our hostage to the
proper desperation for the Big Run."

Srtes switched on the large visi-screen that blanketed the front wall
of his office. "The alien has been wandering through the streets for
the past several hours," he said. "If we are fortunate, Ctvar should
put in his appearance soon."

       *       *       *       *       *

The visi-screen flickered once, cleared, and exposed an outside street.
At the far end the alien--John Wilson, as he called himself--walked
slowly, with his head down, and his hands in the pockets of the
outlandish jacket he had brought with him. He proceeded aimlessly, with
a peculiar, jerky, movement of his limbs. Perhaps he was lonesome for
his home world, and uncertain of what awaited him.

A party of Zade men left a drinking place just ahead of him. They were
quarreling--without any particular rancor--and one of them was loudly
keening a verse of hunting song. At their forefront strode a burly Zade
with a bush of red-orange hair.

"The big one is the crewman I mentioned," Srtes pointed out.

The burly Zade spied the alien and a pleased burst of laughter rumbled
up from his chest. "Our unwinged friend from Earth!" he shouted. It was
a deadly insult.

As the alien stopped uncertainly, Ctvar and his friends crowded around
him. "Are all Earthlings wingless freaks?" one of them asked in a loud
voice. The others laughed.

I expected the alien to show some fight, but he only stood silently.

The party of Zades showed their contempt by increasing the tempo of
their insults. Still the Earthling did nothing.

Finally Ctvar became disgusted with the other's spinelessness and spat
in his face, at the same time reaching out to grab him.

I heard several gasps from those around me as the alien moved. His
actions the next moment were almost too swift for us to follow. He
spread his legs slightly, as Ctvar reached for him, and swung his
right fist. An instant later Ctvar lay on the ground. One leg made a
continuous kicking motion, but it was only a reflex action. Ctvar had
been knocked unconscious!

The shouting of the other Zades quieted to an ugly murmur, and they
surged forward. The Earthling set his back against the building behind
him and struck out at his attackers, but they overwhelmed him by sheer
numbers and dragged him to the ground.

They beat him and stamped several times on his body before a squad of
sentinels appeared and broke them up.

"A fine start," Srtes said.

"Unless he is already dead."

"I don't believe he is," Srtes answered. "But if he is no more hardy
than that, there will be no necessity for us to learn more."

       *       *       *       *       *

The Earthling proved to be much hardier. And more stubborn.

The sentinels, of course, gave him no further help. They would not have
stopped the fight, except that they had orders from Srtes to save our
visitor from any disabling injury, if at all possible.

The Earthling lay on the ground for only a short while before he pulled
himself to a sitting position. His face was bruised, blood ran from his
nose, and one eye was swollen and closed. With the other he followed
the progress of Ctvar and his party as they went on to the next
drinking place.

When he climbed to his feet his left leg buckled but he limped about
on it for a few minutes until he could walk. He strode purposefully
toward the drinking place Ctvar's party had entered, and pushed his way
inside.

Someone behind me muttered angrily. There was no pick-up in the
drinking place and we could only watch the exterior of the building.

We did not have long to wait. The sound of commotion inside reached us
soon after the alien entered. A short time later he tumbled out through
the doorway. His body was limp as it landed in the dirt street. He lay
motionless. A few minutes later we caught another view of Ctvar. He and
two of his friends were carried from the drinking place.

The alien did not recover so quickly this time. His first movement was
a slow rocking of his head. At each motion a low groan came from his
lips. He made several attempts to regain his feet, but his legs would
not hold him. At last he began crawling toward his room a few blocks
away. He left a small trail of blood behind him.

It took him almost an hour of crawling, between rests, to reach his
room.

I left Srtes' office with the council members. There would be little to
observe for some days, and that little I could watch on the screen in
my own cubicle.

       *       *       *       *       *

All the next day the alien lay on his sleeping rug. He rose only
in response to his nature calls, and once to fix himself a bowl of
porridge. However, the following afternoon, though he was obviously
still not at all physically fit, he dressed and left his room.

It took me a few minutes after he reached the street to realize that
he was heading for the Building Administrates. Undoubtedly to complain
to Srtes of the treatment he had received at the hands of Ctvar and
his party. And just when I was beginning to have some small amount of
respect for the outworlder.

I switched hurriedly to Srtes and informed him of the imminent visit.
At the same time I requested permission to cover the interview. The
request was granted.

       *       *       *       *       *

Srtes' visitor surprised us by making no complaint against Ctvar, and
requesting no protection.

He declined the hassocks Srtes offered him, and stood with his hands
clasped behind his back. "I've heard nothing from you for some time
now," he said. "Does that mean your examiners are finished with me?"

"That is correct," Srtes answered courteously.

"What comes next?" he asked.

"Next?" Srtes repeated. "Why, that is your own decision. My interest in
you ceased the day our study was complete. You are free now to do as
you wish."

The alien thought that over for a time. "You do not intend to return me
to Earth?" he asked.

"Is there any reason why you should expect us to?" Srtes replied.

"To me it seems there is," he said. "I fulfilled my part of the
contract. Shouldn't I expect you, as a fair return, to see that I got
back to Earth?"

Srtes' expression betrayed a mild irritation. "We had no contract," he
said. "You were given to us to do with as we wished. Now that our study
is completed, we owe you nothing."

"I expected as much," the alien said, almost without interest. "Will
you tell me then, what I can do to help myself? I presume you do not
intend to furnish me with food and shelter indefinitely."

"You will be permitted to keep your room until you find new quarters.
The rest is your own responsibility."

He considered that for a long moment. "Do you have any suggestions as
to how I might go about earning my living?" he asked.

"If you have any serviceable skill, you will probably be able to find
employment for it. If not--" Sites shrugged.

"How would I know what skills would be useful here? I know practically
nothing about you."

"I'm afraid that's your own problem," Srtes said. "If you are unable to
adapt, you will not survive. It is the natural law."

The alien's eyes narrowed. He seemed to be holding in check a cold
anger. "Tell me," he said. "Do you consider yourselves just?"

Srtes' hair bristled until his head appeared twice its normal size. He
half rose from his hassock, then slowly resumed his seat. I admired his
self-restraint.

"We consider ourselves extremely fair," he said carefully. "Only the
strong have the right to survive, and the fact that they do survive
proves their strength. What you are determines your end. We are
demanding nothing more from you than we expect from our own citizens.
Weaklings and inefficients are perishing every day on the ragged
confines of our civilization. In simple justice I can offer you nothing
more."

The Earthling's shoulders had gradually drooped as Srtes spoke. "Yours
is a harsh philosophy," he mumbled at the end.

"It is our means of being certain that we maintain our race's fitness,"
Srtes explained patiently. "On this world only the strong and their
progeny survive. As long as that natural struggle continues the
strength of each generation will become greater."

The alien seemed to recognize Srtes' sincerity. He rose tiredly.
"Thanks, for the explanation at least," he said, as he left the office.

       *       *       *       *       *

The next step would be mine. During the rest of the afternoon, as I
watched on the visi-screen, the Earthling kept to his room. Most of the
day he lay on his sleeping rug, with his eyes wide open, staring at the
ceiling. The rest of the time he paced aimlessly. The next morning he
ate the last of his porridge, and as the day progressed I recognized
that much of his unrest must be prompted by hunger. Yet his battered
body needed the rest he was giving it.

He napped shortly after dusk, but only for a short time. When he awoke
he put on his jacket and went outside. On the screen I followed his
forlorn wanderings about the city.

After several hours he stopped and leaned against a wooden building.
The night breeze had risen to its near-gale intensity by this time, and
he pulled his jacket closer about him. It was only a few degrees below
freezing, and he should have been warm enough, but I understood his
race was unable to withstand any great degree of cold. And he was sore
and hungry.

I received my call from Srtes then. He and the council had decided that
the alien had reached the proper depth of misery and hopelessness. I
was to contact him--and set him for the Big Run.

       *       *       *       *       *

I found him still leaning against the same wooden building. He looked
up at me from under his heavy brows as I neared him. I kept a safe
distance between us. I remembered Ctvar. "Will you allow me to buy you
something to eat?" I asked, deciding to use a direct approach.

I liked the way he did not ask any questions. He merely regarded me for
a moment longer, then made his nodding motion.

All through the meal in the public eating place he remained silent. He
ate hungrily but without haste and only when he'd finished did he speak
again. "Why?" he asked.

"I do not understand what you mean," I evaded.

"I haven't learned much about you Zades since I've been here," he said,
"but I have learned that you do nothing out of kindness. What do you
want from me?"

I forced myself to smile. "You are right, of course," I said. "I do
want something from you. Information about your world. In return for
your cooperation I will see that you continue to be well fed."

"I thought Srtes was through with me," he said.

"My interest is strictly personal," I answered. "I am what you would
call a reporter. We give out our news on disseminators similar to your
television."

I had caught his interest. I suppose he was eager to learn anything
that he might use to make his way. "I've seen no signs of television,"
he said.

"This is one of our smaller cities," I improvised quickly. "There are
only a few receiving sets here. Most of them are in the main halls of
the various clans."

The explanation satisfied him. "Just what do you want to know?" he
asked.

"Anything about your Earth that you think might be of interest to my
listeners."

"Couldn't you get that from Srtes and his staff?"

"Their supply of information is limited. You should be able to give me
much more."

He was actually eager to talk. It probably relieved his homesickness.
We returned to his room, and our conversation took up most of the rest
of the night. Toward morning he began questioning me.

"I've given you all the information you asked for," he said. "Now I'd
like some in return. Can you suggest any way I can make a living on
this world of yours?"

I thought for a moment. "You might be able to introduce some product of
your civilization's technology that would be useful here. Not knowing
your world, I couldn't suggest just what."

"I should be able to come up with something," he said thoughtfully.
"Would I be allowed to manufacture and sell it if I did?"

"If you can demonstrate that you can do it better than anyone else, you
will be given an exclusive right to control both its construction and
distribution."

"Does that apply to every function of your society?" he asked.

"This world belongs to those who can prove their strength," I answered.

"That's a bit different than on Earth," he said. "We have always held
that competition makes for the best results."

I had become quite interested in the discussion, and found myself
giving a rather lengthy explanation of that part of our society's
functioning. "Competition is very real here, even though it is less
tangible than yours. The fact that a producer of a product or service
may be displaced by anyone demonstrating a better or more efficient
product or method, acts as a spur to best efforts. The price is set
by the state, with the prices of competing bidders in mind. Under our
system time and energy is not wasted making inferior goods, or those
already in adequate supply. The purchasers, also, are never exposed to
an inferior article."

I was becoming quite drowsy by this time and left after I'd answered a
few more of his questions. I felt affection toward the Earthling. He
was direct and honest. Beneath his placid manner he had a pride as
fierce as any Zade. Tomorrow would be the crucial day for him.

       *       *       *       *       *

Late the next afternoon I bought a packet of food and brought it to the
outworlder's room. "Did you have trouble with a Zade named Ctvar?" I
asked him, immediately on entering.

"Yes, I did," he answered. "Why?"

"His clansmen have been pouring into the city all day. I just learned
that they are looking for you."

His eyes widened slightly. "Isn't Ctvar able to handle his own trouble?"

"Ctvar is dead."

He seemed unable at first to find the words to speak. At last he said,
"It happened in a fight that he started. Why should they seek revenge?"

"They would be poor clan brothers if they did not avenge him," I
answered.

"Won't your sentinels do anything to stop them?" he asked.

"They won't help you," I answered. "You make no contribution to the
state that would entitle you to their protection."

"Don't you have laws against this sort of thing?"

"An undetermined number of persons wish you dead. You, and perhaps I,
want you to live. The majority is against us."

"But I'm at least entitled to a trial."

I puzzled over his meaning of the word, but could find no sure answer.
"I don't know what the purpose of a trial would be," I said. "But it
could change nothing. You have the ill will of many citizens."

He stared at the floor without any further questions.

Against the strong logic of my reasoning I felt a strong empathy toward
him. He had conducted himself well on this world that must seem very
strange to him. I offered what consolation I could. "There is this
possibility," I said. "A majority is not always reckoned by numbers.
If you can collect superior strength to your side--either by getting
others to help you, or by your own ingenuity--and whip Ctvar's clan,
the law will do nothing to punish you. You may even kill them with
impunity, except for the revenge of the other clansmen."

"That's a small hope."

"It is," I agreed, belatedly recalling to mind my mission. I was
probably this minute under disapproving observation. "You can't hope to
fight them all," I continued. "That is why I would earnestly suggest
that you run."

"To where would I run?"

"I gave that a good deal of thought on my way here," I said. "There's
a space ship--on a meadow outside the walls, on the far side of the
city--that you might be able to reach. You could take it and flee to
your own world, probably the only place where you'd be safe."

"I wouldn't know how to operate it."

"The ship is very nearly automatic. Look," I said. I took a sheet of
velum, and a stylus, and drew three circles with smaller circles
beneath them. "These represent the dials on the ship's control panel.
The bubbles in the first dial must be set in this order--you'd better
memorize them--blue-blue-yellow-blue-yellow. That's the range for
your Earth. You'll have to shrink the last yellow bubble to about
three-quarter size. That will give you a safety leeway. The ship will
take itself in on motors from there.

"This second dial starts the ship. You merely squeeze the knob beneath
it. The third dial is for stopping. As you are about to land, the
tighter you grip the knob, the slower the ship will settle. You
shouldn't have any trouble manipulating it."

His spirits seemed to revive somewhat. "It's worth a try," he said. "I
have nothing to lose."

"It's only a few hours to night-fall," I told him. "That will be the
best time to try getting through the city. I'd suggest you eat a good
meal, and fix yourself a lunch to take along. Then nap if you can."

       *       *       *       *       *

I was back in Srtes' office, watching the big screen, with the eight
council members, when the alien started out. That was shortly after
dusk. It is never completely dark on Zade.

He was shrewd enough to leave his room the back way, I observed. There
was no rear door, but he let himself down from the balcony, dropping
the last few feet to the ground.

"He is wearing a sword, I see," a white haired councilor remarked.

"Yes," Srtes answered. "He was given it when they were testing his
weapons adaptability. But the fool filed it down until it is hardly
thicker than a reed. It will be a poor weapon."

The alien hugged the wall of the house, and after glancing into the
opening between it and the next, scurried quickly across. Two buildings
farther on the rear court ended, and he had to go around to the front.
When he reached the yellow pedestrian walk he did not turn, as we might
have expected, but went on across a second courtyard.

"He realizes that the normally travelled yellow walks would not be very
safe," Srtes said. "I wonder how long it will take him to solve the
enigma of the others."

At the next white street he turned to his right. When he reached the
end and learned that he had gone up a blind alley he retraced his steps
and went across to a perpendicular blue street. He seemed a bit nervous
now.

A third of the way down the blue walk he ran into the invisible
electric shock wall, and staggered backward. The lunch packet that
he carried fell from his hand, and he was obviously too stunned to
remember to pick it up as he started back.

He had retreated only a short way before he paused and stood
considering his situation. After a minute he returned and examined the
buildings at each side of the electrified area. He must have found that
the conduction outlets did not extend to the ground, for soon he began
crawling forward on his hands and knees.

"A point for the alien," I heard Srtes murmur. I detected a hint of
admiration in his voice.

The alien kept his caution, for when the ground caved beneath his hand,
at the end of the third street, he did not fall into the trap. He
simply rolled back and lay quietly for a moment. Another decision.

He was equal to it. Rising to his feet, he took a short run and
leaped for the balcony on the nearest building. From there it was an
easy matter to reach the roof. Observing carefully below before each
venture, he leaped from roof to roof until he reached the end of the
street.

We lost him for a short time then. He had gone down into the last
house. A few minutes later a guard in front of the door stumbled
abruptly backward and disappeared inside.

Another moment passed and the guard reappeared. He walked briskly up
two streets before we became aware of what had happened. The alien had
changed to the guard's clothes!

That would not take him far, of course. At the beginning of the third
street he was stopped by two sentries. When they demanded a password,
he whipped his sword out from beneath his cloak and ran the nearest
through. The second shouted for help and drew his own sword. He offered
only a moment of resistance. We saw then the alien's reason for
grinding down the long sword. He handled it almost like a whip, and the
sentry was unable to parry his swift thrusts.

As I noted the councilors' exchange of wondering glances I understood
that a new weapons concept had been born.

When the second sentry fell, the alien sprinted into the house, and
reappeared a minute later on the roof. Soon he was a block away from
the scene of the fight.

The sentries at the second intersection had run back in answer to the
shout for help, and the alien was able to cross the street unmolested.
Once again he took to the roof, and when he came down again he had
reached the Building Administrates. He was directly below us!

We followed him on the screen as he ran down the stairs to the
basement. A sound from the front of the building attracted our
attention and we switched back. Two sentinels had not been caught off
guard. They had spotted him entering Administrates and were following
closely.

We switched back to the fugitive, and just in time. He had dragged
himself almost all the way under the bottom ramp of the stairs. Soon
he had disappeared entirely. Now the sentinals were looking about in a
confused way.

I heard Srtes beside me sigh heavily as he rose to his feet. "Do you
realize," he asked no one in particular, "that he is already half-way
through? All our calculations pointed to the odds being heavily against
his reaching this far."

"The sentinels will find him in a few minutes," one of the councilors
said reassuringly.

"Of course they will!" Srtes replied angrily. "But he was not supposed
to be able to get this far."

       *       *       *       *       *

The alien stayed beneath the ramp only until his pursuers ran past.
Immediately after, he reappeared and strode without hesitation toward
the nearest air vent. The screen stuck when he gripped its spokes and
tried to turn it, but he exerted his strength and it gave slowly. He
pulled it from its frame and let it rest on the floor.

Pushing his feet through the vent opening, still clutching the screen,
he let himself down. Soon his feet came to rest on the inside ledge of
the air tunnel and he balanced there as he screwed the screen back into
place. He had vanished by the time the sentinels came running back.

"By the great hound of Hagras!" a councilor exclaimed. "Is there no end
to the creature's ingenuity?"

None of us paid any attention to him; we were too busy watching the
scene below. Only Srtes spoke. "Will the fools have brains enough to
look for him down there?" he muttered. The excitement of the chase had
obviously gripped him also. He clicked on a control button that split
the screen into two scenes, and we were able to watch the activity
above, as well as in the tunnels below.

We had no trouble following the flight of the alien. The lining of the
tunnels had been prepared with a luminous coating that gave enough
light for us to see the inside clearly.

As we watched, the alien stumbled and fell to the floor. He lay for a
long moment, too weary to rise. By this time he must be exhausted. His
stamina had already proven greater than we had anticipated.

He rose again and walked doggedly on, searching absent-mindedly in
his pockets as he went. I knew he must be hungry and thirsty. He was
probably only now remembering the packet he had lost early in his
flight. But he did not slow his steady progress forward.

On the right half of the screen we noted that the captain of the
sentinels had evidently figured out what had happened. Up ahead his men
were hurrying into the numerous branches of the air tunnel and blocking
every passage. As they had probably been ordered, they began walking
slowly back. We kept our attention on the one who would intercept the
fugitive.

The alien stopped occasionally and stood listening. Once he paused
longer than usual. Was his hearing that good, I wondered, or was he
just being cautious? After a minute he moved forward again, until only
a fairly long bend in the tunnel branch separated him from the oncoming
sentinel.

This time he did hear his interceptor. He ran quickly back, keeping a
close observation on the wall to his left as he went. Soon he found the
hiding place he sought. Probably he had noted it in passing before, and
had kept it in mind for an emergency of this kind.

Where he stopped a connection in the sheet metal lining the tunnel had
come loose and a dark space gaped open. He crawled inside.

The man was stupid, I thought, if he expected the sentinel to pass
without noticing the hiding place.

The sentinel was not stupid. But then, we soon found out, neither was
the alien.

When the sentinel came to the opening he paused and jabbed tentatively
into the dark cavity with the long sword that he carried in his hand.
An instant later he stumbled forward, his knees gave beneath him, and
he sagged to the floor.

After a moment the alien emerged. A portion of his cloak was wrapped
around one hand, his sword in the other. We understood then what had
happened. He had grasped the sentinel's sword in his padded hand and
jerked him forward, at the same time thrusting out with his own weapon.
The sentinel had been wounded critically.

However, the alien himself had not escaped unscathed. As he unbuttoned
his jacket we could see a large spot of blood on the lighter surface of
his blouse. He took a white cloth from a rear pocket of his trousers
and pressed it between his jacket and the wound. When he went on this
time he was very weary, obviously dredging up the last dregs of his
strength.

In the short pause from action on the screen I looked around me. I was
the only one in the room still sitting. The others had been unable to
keep their seats during the excitement of watching the flight of the
fighting alien. Some stood tensely or leaned against the walls, others
paced restlessly, and one knelt on his hassock.

I returned my attention to the outside half of the screen. The captain
of the sentinels was letting gas into the tunnel!

I felt a pang of regret. This was the beginning of the end. I wondered
then if the alien did not have some inkling by this time that there was
more to this than a mere seeking of revenge by Ctvar's kinsmen.

He went on only a few strides farther before he detected the gas.
Even then his ingenuity did not desert him. As he stood with his
nostrils spread a noise above him caused him to look up. He spied a
metal covered opening into the tunnel directly over his head. A dozen
sentinels, I saw with a side glance, were grouped around it.

After only a brief hesitation the alien returned to the Zade he had
wounded a few minutes before. The man had ceased to move. Evidently he
was dead.

The alien tossed the dead sentinel across his shoulders and carried
him to the spot beneath the metal cover. Here he reached up and tapped
sharply. The cover moved back cautiously, and the alien rammed the
corpse upward, head foremost.

The body struck the cover and knocked it aside. The alien shoved it a
bit higher, and it quivered as the swords above pierced it.

He dropped the dead carcass and sprinted forward. He had bought all
the time he could, and there was nothing for him to do now except
try to reach the end of the tunnel before the gas overcame him. His
head was held high as he ran--he had deduced that they had to use a
heavier-than-air gas. He did not have far to go.

He reached the end of the tunnel and stumbled onto a conduit leading
from the main air compressor. For a short time he lay sprawled across
the metal duct, too exhausted to move. Finally he raised his head and
looked wearily about him. He spied a vent opening on a level with his
head, and with a determined effort he removed the screen and climbed
through. Utter fatigue showed in line of his body.

Outside he stood for several minutes, drawing clean air deep into his
lungs. There were no sentries here. They had not expected him to get
this far. But they would come, soon after they failed to flush him from
the tunnel.

The alien looked about, then headed unerringly toward the sand banked
against the wall of the pumping station. He dug until he had made a
long hollow then let his weary body fall into the shallow place and
began piling sand over his legs. When he had covered all of himself
except one arm, he burrowed it down until he was completely hidden from
sight.

"How can such a man be stopped?" Srtes asked. His face was drawn and
gray, as though he had suffered some great defeat.

       *       *       *       *       *

The alien must have dropped off to sleep for he stayed in the sand
for several hours, and did not emerge until shortly before day-light.
Evidently he had first made an opening through which to observe, for
there were no guards about when he stood up and shook the sand from his
body.

He must also have studied all his surroundings. He had reached the
city's end. The wall ahead of him was without a gate. He had been sent
on a foredoomed errand. Though I had been acting under orders, I felt a
kind of shame at the part I had played in the deception.

Even then, however, he was not defeated. He struck out without delay to
his right where there were few sentries, using his rooftop technique
when needed, and reached a side gate within an hour. He dispatched
the final sentry by dropping on him from a convenient balcony--he was
probably too exhausted to risk a fight--and let himself out through the
gate.

He walked with jaded steps back the way he had come, skirting the
outside wall closely. At last he reached the meadow for which he had
started seven hours earlier.

He must have guessed before this that the story of the waiting space
ship was a hoax. But, giving the last of his strength, and hoping
against hope, he had fought his way there. When the first rays of the
morning sun showed him that the meadow was bare and empty his raw
courage deserted him. He fell face forward on the red sand.

"I suggest we conclude our project with a final vote before we leave,"
Srtes said, a few minutes after we watched the alien come to the end of
his resources. "I am certain no one of you can have any doubts as to
what our decision must be." His passive face betrayed no emotion.

"Our plan, decided on soon after we learned of the Humans' existence,"
Srtes' voice droned on, "was to make an early contact. If the Humans
proved a race whose physical and mental strength equaled or surpassed
our own, prudence would indicate that we seek peace. If we found
them weak, we would exterminate them, and take over their world. The
dominant factor in our decision was to be our study of the specimen we
brought back, and how he conducted himself in the Big Run. We have all
seen the results of that experiment."

Srtes looked about the room. "Are we all agreed that the only wise
course--in view of our observations--is to do everything in our power
to establish peaceful relations with the Earthmen?"

There was no dissenting vote.

"When our envoys leave for Earth an honored place will be made for our
visitor," Srtes added.

       *       *       *       *       *

The meeting was over, and the fateful decision had been made. For the
next great tide much of my work would consist in reporting the tearing
down of the Big Run.

The alien had believed it to be one of our cities. It was a great deal
of work, constructing the Big Run to test one alien specimen, but the
results had proven the effort warranted. Now it could be disposed of.

Perhaps this very day we would begin dismantling the giant testing maze.
