                               OH, RATS!

                    Orthedrin, maxiton and glutamic
                   acid--they were the prescription
                   that made him king of his world!


SK540, the 27th son of two very ordinary white laboratory rats,
surveyed his world.

He was no more able than any other rat to possess articulate speech, or
to use his paws as hands. All he had was a brain which, relative to its
size, was superior to any rat's that had hitherto appeared on Earth. It
was enough.

In the first week of gestation his embryo had been removed to a more
suitable receptacle than the maternal womb, and his brain had been
stimulated with orthedrin, maxiton and glutamic acid. It had been
continuously irrigated with blood. One hemisphere had been activated
far in excess of the other, since previous experiments had shown that
increased lack of symmetry between the hemispheres produced superior
mentality. The end-result was an enormous increase in brain-cells
in both hemispheres. His brain showed also a marked increase in
cholinesterase over that of other rats.

SK540, in other words, was a super-rat.

The same processes had been applied to all his brothers and sisters.
Most of them had died. The few who did not, failed to show the desired
results, or showed them in so lopsided and partial a manner that it was
necessary to destroy them.

All of this, of course had been mere preparation and experimentation
with a view to later developments in human subjects. What SK540's gods
had not anticipated was that they would produce a creature mentally the
superior, not only of his fellow-rats, but also, in some respects, of
themselves.

He was a super-rat: but he was still a rat. His world of dreams and
aspirations was not human, but murine.

What would you do if you were a brilliant, moody young super-rat, caged
in a laboratory?

SK540 did it.

What human beings desired was health, freedom, wealth, love, and
power. So did SK540. But to him health was taken for granted; freedom
was freedom from cages, traps, cats, and dogs; wealth meant shelter
from cold and rain and plenty to eat; love meant a constant supply of
available females.

But power! It was in his longing for power that he most revealingly
displayed his status as super-rat.

Therefore, once he had learned how to open his cage, he was carefully
selective of the companions--actually, the followers--whom he would
release to join his midnight hegira from the laboratory. Only the
meekest and most subservient of the males--intelligent but not too
intelligent--and the most desirable and amiable of the females were
invited.

Once free of the cages, SK540 had no difficulty in leading his troop
out of the building. The door of the laboratory was locked, but a
window was slightly open from the top. Rats can climb up or down.

Like a silver ribbon they flowed along the dark street, SK540, looking
exactly like all the rest, at their head. Only one person in the
deserted streets seems to have noticed them, and he did not understand
the nature of the phenomenon.

Young Mr. and Mrs. Philip Vinson started housekeeping in what had once
been a mansion. It was now a rundown eyesore.

It had belonged to Norah Vinson's great-aunt Martha, who had left it
to her in her will. The estate was in litigation, but the executor had
permitted the Vinsons to settle down in the house, though they weren't
allowed yet to sell it. It had no modern conveniences, and was full of
rooms they couldn't use and heavy old-fashioned furniture; but it was
solidly built and near the laboratory where he worked as a technician,
and they could live rent-free until they could sell the house and use
the money to buy a real home.

"Something funny happened in the lab last night," Philip reported,
watching Norah struggle with dinner on the massive coal-stove.
"Somebody broke in and stole about half our experimental animals. And
they got our pride and joy."

"The famous SK540?" Norah asked.

"The same. Actually, it wasn't a break-in. It must have been an inside
job. The cages were open but there were no signs of breaking and
entering. We're all under suspicion till they find out who-dunit."

Norah looked alarmed.

"You too? What on earth would anybody want with a lot of laboratory
rats? They aren't worth anything, are they--financially, I mean?"

"Not a cent. That's why I'm sure one of the clean-up kids must have
done it. Probably wanted them for pets. They're all tame, of course,
not like wild rats--though they can bite like wild rats if they want
to. Some of the ones missing are treated, and some are controls. It
would just be a nuisance if they hadn't taken SK540. Now they've
got to find him, or do about five years' work over again, without
any assurance of as great a success. To say nothing of letting our
super-rat loose on the world."

"What on earth could even a super-rat do that would matter--to human
beings, I mean?"

"Nobody knows. Maybe that's what we're going to find out."

       *       *       *       *       *

That night Norah woke suddenly with a loud scream. Philip got the
gas lighted--there was no electricity in the old house--and held her
shaking body in his arms. She found her breath at last long enough to
sob: "It was a rat! A rat ran right over my face!"

"You're dreaming, darling. It's because I told you about the theft at
the lab. There couldn't be rats in this place. It's too solidly built,
from the basement up."

He finally got her to sleep again, but he lay awake for a long time,
listening. Nothing happened.

Rats can't talk, but they can communicate. About the time Norah Vinson
dropped off after her frightened wakening, SK540 was confronting a
culprit. The culprit was one of the liberated males. His beady eyes
tried to gaze into the implacable ones of SK540, but his tail twitched
nervously and if he bared his teeth it was more in terror than in
fight. They all knew that strict orders had been given not to disturb
the humans in the house until SK540 had all his preparations made.

A little more of that silent communication, and the rat who had run
over Norah's face knew he had only two choices--have his throat slit or
get out. He got.

"What do you know?" Philip said that evening. "One of our rats came
back."

"By itself?"

"Yeah. I never heard of such a thing. It was one of the experimental
ones, so it was smarter than most, though not such an awful lot. I
never heard of a rat with homing instinct before. But when we opened up
this morning, there he was, sitting in his cage, ready for breakfast."

"Speaking of breakfast, I thought I asked you to buy a big box of
oatmeal on your way home yesterday. It's about the only thing in the
way of cereal I can manage on that old stove."

"I did buy it. Don't you remember? I left it in the kitchen."

"Well, it wasn't there this morning. All I know is that you're going to
have nothing but toast and coffee tomorrow. We seem to be out of eggs,
too. And bacon. And I thought we had half a pound left of that cheese,
but that's gone too."

"Good Lord, Norah, if you've got that much marketing to do, can't you
do it yourself?"

"Sure, if you leave the car. I'm not going to walk all that way and
back."

So of course Philip did do the shopping the next day. Besides, Norah
had just remembered she had a date at the hairdresser's.

       *       *       *       *       *

When he got home her hair was still uncurled and she was in hysterics.
One of the many amenities great-aunt Martha's house lacked was a
telephone; anyway, Norah couldn't have been coherent over one. She cast
herself, shuddering and crying, into Philip's arms, and it was a long
time before he got her soothed enough for her to gasp: "Philip! They
wouldn't let me out!"

"They? Who? What do you mean?"

"The--the rats! The white rats. They made a ring around me at the front
door so I couldn't open it. I ran to the back and they beat me there
and did the same thing. I even tried the windows but it was no use. And
their teeth--they all--I guess I went to pieces. I started throwing
things at them and they just dodged. I yelled for help but there's
nobody near enough to hear. Then I gave up and ran in our bedroom and
slammed the door on them, but they left guards outside. I heard them
squeaking till you drove up, then I heard them run away."

Philip stared at her, scared to death. His wife had lost her mind.

"Now, now, sweetheart," he said soothingly, "let's get this straight.
They fired a lab boy today. They found four of our rats in his home.
He told some idiotic story of having 'found' them, with the others
missing, running loose on the street that night, but of course he stole
them. He must have sold the rest of them to other kids; they're working
on that now."

Norah blew her nose and wiped her eyes. She had regained her usual calm.

"Philip Vinson," she said coldly, "are you accusing me of lying, or
just of being crazy? I'm neither. I saw and heard those rats. They're
here _now_. What's more, I guess I know where that oatmeal went, and
the eggs and bacon too, and the cheese. I'm--I'm a hostage!

"I don't suppose," she added sarcastically, "that your SK540 was one of
the ones they found in the boy's home?"

"No, it wasn't," he acknowledged uneasily. A nasty little icy trickle
stole down his spine. "All right, Norah, I give in. You take the poker
and I'll take the hammer, and we'll search this house from cellar to
attic."

"You won't find them," said Norah bitterly. "SK540's too smart. They'll
stay inside the walls and keep quiet."

"Then we'll find the holes they went through and rout them out."

They didn't, of course. There wasn't a sign of a rathole, or of a rat.

They got through dinner and the evening somehow. Norah put all the
food not in cans inside the old-fashioned icebox which took the place
of a refrigerator. Philip thought he was too disturbed to be able to
sleep, but he did, and Norah, exhausted, was asleep as soon as her head
touched the pillow.

His last doubt of his wife's sanity vanished when, the next morning,
they found the icebox door open and half the food gone.

       *       *       *       *       *

"That settles it!" Philip announced. "Come on, Norah, put your coat
on. You're coming with me to the lab and we'll report what's happened.
They'll find those creatures if they have to tear the house apart to do
it. That boy must have been telling the truth."

"You couldn't keep me away," Norah responded. "I'll never spend
another minute alone in this house while those dreadful things are in
it."

But of course when they got to the front door, there they were,
circling them, their teeth bared. The same with the back door and all
the first floor windows.

"That's SK540 all right, leading them," Philip whispered through
clenched jaws. He could smash them all, he supposed, in time, with what
weapons he had. But he worked in the laboratory. He knew their value to
science, especially SK540's.

Rats couldn't talk, he knew, and they couldn't understand human speech.
Nevertheless, some kind of communication might establish itself.
SK540's eyes were too intelligent not to believe that he was getting
the gist of talk directed to him.

"This is utterly ridiculous," Philip grated. "If you won't let us out,
how can we keep bringing food into the house for you? We'll all starve,
you and we together."

He could have sworn SK540 was considering. But he guessed the implicit
answer. Let either one of them out, now they knew the rats were there,
and men from the laboratory would come quickly and overwhelm and carry
off the besiegers. It was a true impasse.

"Philip," Norah reminded him, "if you don't go to work, they know we
haven't a phone, and somebody will be here pretty soon to find out if
anything's wrong."

But that wouldn't help, Philip reflected gloomily; they'd let anyone
in, and keep him there.

And he thought to himself, and was careful not to say it aloud: rats
are rats. Even if they are 25th generation laboratory-born. When the
other food was gone there would be human meat.

He did not want to look at them any more. He took Norah's arm and
turned away into their bedroom.

They stayed there all day, too upset to think of eating, talking and
talking to no conclusion. As dusk came on they did not light the gas.
Exhausted, they lay down on the bed without undressing.

After a while there was a quiet scratching at the door.

"Don't let them in!" Norah whispered. Her teeth were chattering.

"I must, dear," he whispered back. "It isn't 'them,' I'm sure of
it--it's just SK540 himself. I've been expecting him. We've got to
reach some kind of understanding."

"With a rat?"

"With a super-rat. We have no choice."

Philip was right. SK540 alone stood there and sidled in as the door
closed solidly again behind him.

How could one communicate with a rat? Philip could think of no way
except to pick him up, place him where they were face to face, and talk.

"Are your--followers outside?" he asked.

A rodent's face can have no expression, but Philip caught a glance of
contempt in the beady eyes. The slaves were doubtless bedded down in
their hideaway, with strict orders to stay there and keep quiet.

"You know," Philip Vinson went on, "I could kill you, very easily." The
words would mean nothing to SK540; the tone might. He watched the beady
eyes; there was nothing in them but intelligent attention, no flicker
of fear.

"Or I could tie you up and take you to the laboratory and let them
decide whether to keep you or kill you. We are all much bigger and
stronger than you. Without your army you can't intimidate us."

There was, of course, no answer. But SK540 did a startling and touching
thing. He reached out one front paw, as if in appeal.

Norah caught her breath in astonishment.

       *       *       *       *       *

"He--he just wants to be free," she said in a choked whisper.

"You mean you're not afraid of him any more?"

"You said yourself he couldn't intimidate us without his army."

Philip thought a minute. Then he said slowly:

"I wonder if we had the right to do this to him in the first place. He
would have been an ordinary laboratory rat, mindless and contented;
we've made him into a neurotic alien in his world."

"You're not responsible, darling; you're a technician, not a
biochemist."

"I share the responsibility. We all do."

"So what? The fact remains that it was done, and here he is--and here
we are."

The doorbell rang.

Philip and Norah exchanged glances. SK540 watched them.

"It's probably Kelly, from the lab," Philip said, "trying to find out
why I wasn't there today. It's just about quitting time, and he lives
nearest us."

Norah astonished him. She picked up SK540 from the bed-side table where
Philip had placed him, and hid him under her pillow.

"Get rid of whoever it is," she said defensively. Philip stared for an
instant, then walked briskly downstairs. He was back in a few minutes.

"It was Kelly, all right," he told her. "I said you were sick and I
couldn't leave you to phone. I said I'd be there tomorrow. Now what?"

SK540's white whiskers emerged from under the pillow, and he jumped
over to the table again. Norah's cheeks were pink.

"When it came to the point, I just couldn't," she explained
shamefacedly. "I suddenly realized that he's a _person_. I couldn't let
him be taken back to prison."

"Aren't you frightened any more?"

"Not of him." She faced the super-rat squarely. "Look," she said, "if
we take care of you, will you get rid of that gang of yours, so we can
be free too?"

"That's nonsense, Norah," Philip objected. "He can't possibly
understand you."

"Dogs and cats learn to understand enough, and he's smarter than any
dog or cat that ever lived."

"But--"

The words froze on his lips. SK540 had jumped to the floor and run to
the door. There he stood and looked back at them, his tail twitching.

"He wants us to follow him," Norah murmured.

There was no sign of a hole in the back wall of the disused pantry.
But behind it they could hear squeaks and rustlings.

SK540 scratched delicately at almost invisible cracks. A section of the
wall, two by four inches, fell out on the floor.

"So that's where some of the oatmeal went," Norah commented. "Made into
paste."

"Sh!"

SK540 vanished through the hole. They waited, listening to
incomprehensible sounds. Outside it had grown dark.

       *       *       *       *       *

Then the leader emerged and stood to one side of the long line that
pattered through the hole. The two humans stared, fascinated, as the
line made straight for the back door and under it. SK540 stayed where
he was.

"Will they go back to the lab?" Norah asked.

Philip shrugged.

"It doesn't matter. Some of them may ... I feel like a traitor."

"I don't. I feel like one of those people who hid escaped war prisoners
in Europe."

When the rats were all gone, they turned to SK540. But without a glance
at them he re-entered the hiding-place. In a minute he returned,
herding two white rats before him. He stood still, obviously expectant.

Philip squatted on his heels. He picked up the two refugees and looked
them over.

"Both females," he announced briefly. "And both pregnant."

"Is he the father?"

"Who else? He'd see to that."

"And will they inherit his--his--"

"His 'super-ratism'? That's the whole point. That's the object of the
entire experiment. They were going to try it soon."

The three white rats had scarcely moved. The two mothers-to-be had
apparently fallen asleep. Only SK540 stood quietly eying the humans.
When they left him to find a place where they could talk in private he
did not follow them.

"It comes down to this," Philip said at the end of half an hour's
fruitless discussion. "We promised him, or as good as. He believed us
and trusted us.

"But if we keep to our promise we're _really_ traitors--to the human
race."

"You mean, if the offspring should inherit his brain-power, they might
overrun us all?"

"Not might. Would."

"So--"

"So it's an insoluble problem, on our terms. We have to think of this
as a war, and of them as our enemies. What is our word of honor to a
rat?"

"But to a super-rat--to SK540--"

As if called, SK540 appeared.

Had he been listening? Had he understood? Neither of them dared to
voice the question aloud in his presence.

"Later," Philip murmured.

"We must eat," said Norah. "Let's see what's left in the way of food."

       *       *       *       *       *

Everything tasted flat; they weren't very hungry after all. There was
enough left over to feed the three rats. But they had evidently helped
themselves earlier; they left the scraps untasted.

Neither of the humans guessed what else had vanished from the pantry
shelves--what, when he had heard enough, SK540 had slipped away and
sprinkled on the remaining contents of the icebox, wherever the white
powder would not show.

They did not know until it was too late--until both of them lay
writhing in their last spasms on their bedroom floor.

By the time the house was broken into and their bodies found, SK540 and
his two wives were far away, and safe....

And this, children, is the true account, handed down by tradition from
the days of our great Founder, of how the human race ceased to exist
and we took over the world.
