The Gravity Business


Illustrated by ASHMAN

This little alien beggar could dictate his own terms, but how could he—and how could anyone find out what those terms might be?

The flivver descended vertically toward the green planet circling the old, orange sun.

It was a spaceship, but not the kind men had once dreamed about. The flivver was shaped like a crude bullet, blunt at one end of a fat cylinder and tapering abruptly to a point at the other. It had been slapped together out of sheet metal and insulation board, and it sold, fully equipped, for $15,730. It didn't behave like a spaceship, either.

As it hurtled down, its speed increased with dramatic swiftness. Then, at the last instant before impact, it stopped. Just like that.

A moment later, it thumped a last few inches into the ankle-deep grass and knee-high white flowers of the meadow. It was a shock of a jar that made the sheet-metal walls boom like thunder machines. The flivver rocked unsteadily on its flat stern before it decided to stay upright.

Then all was quiet—outside.

Inside the big, central cabin, Grampa waved his pircuit irately in the air. "Now look what you made me do! Just when I had the blamed thing practically whipped, too!"

Grampa was a white-haired 90-year-old who could still go a fast round or two with a man (or woman) half his age, but he had a habit of lapsing into tantrum when he got annoyed.

"Now, Grampa," Fred soothed, but his face was concerned. Fred, once called Young Fred, was Grampa's only son. He was sixty and his hair had begun to gray at the temples. "That landing was pretty rough, Junior."

Junior was Fred's only son. Because he was thirty-five and capable of exercising adult judgment and because he had the youngest adult reflexes, he sat in the pilot's chair, the control stick between his knees, his thumb still over the Off-On button on top. "I know it, Fred," he said, frowning. "This world fooled me. It has a diameter less than that of Mercury and yet a gravitational pull as great as Earth."

Grampa started to say something, but an 8-year-old boy looked up from the navigator's table beside the big computer and said, "Well, gosh, Junior, that's why we picked this planet. We fed all the orbital data into Abacus, and Abacus said that orbital perturbations indicated that the second planet was unusually heavy for its size. Then Fred said, 'That looks like heavy metals', and you said, 'Maybe uranium—'"

"That's enough, Four," Junior interrupted. "Never mind what I said."

Those were the Peppergrass men, four generations of them, looking remarkably alike, although some vital element seemed to have dwindled until Four looked pale and thin-faced and wizened.

"And, Four," Reba said automatically, "don't call your father 'Junior.' It sounds disrespectful."

Reba was Four's mother and Junior's wife. On her own, she was a red-haired beauty with the loveliest figure this side of Antares. That Junior had won her was, to Grampa, the most hopeful thing he had ever noticed about the boy.

"But everybody calls Junior 'Junior,'" Four complained. "Besides, Fred is Junior's father and Junior calls him 'Fred.'"

"That's different," Reba said.

Grampa was still waving his puzzle circuit indignantly. "See!" The pircuit was a flat box equipped with pushbuttons and thirteen slender openings in the top. One of the openings was lighted. "That landing made me push the wrong button and the dad-blasted thing beat me again."

"Stop picking on Junior," Joyce said sharply. She was Junior's mother and Fred's wife, still slim and handsome as she approached sixty, but somehow ice water had replaced the warm blood in her veins. "I'm sure he did the best he could."

"Anybody talks about gravitational pull," Grampa said, snorting, "deserves anything anybody could say about him. There's no such thing, Junior. You ought to know by now that gravitation is the effect of the curving of space-time around matter. Einstein proved that two hundred years ago."

"Go back to your games, Grampa," Fred said impatiently. "We've got work to do."

Grampa knitted his bushy, white eyebrows and petulantly pushed the last button on his pircuit. The last light went out. "You've got work to do, have you? Whose flivver do you think this is, anyhow?"

"It belongs to all of us," Four said shrilly. "You gave us all a sixth share."

"That's right, Four," Grampa muttered, "so I did. But whose money bought it?"

"You bought it, Grampa," Fred said.

"That's right! And who invented the gravity polarizer and the space flivver? Eh? Who made possible this gallivanting all over space?"

"You, Grampa," Fred said.

"You bet! And who made one hundred million dollars out of it that the rest of you vultures are just hanging around to gobble up when I die?"

"And who spent it all trying to invent perpetual motion machines and longevity pills," Joyce said bitterly, "and fixed it so we'd have to go searching for uranium and habitable worlds all through this deadly galaxy? You, Grampa!"

"Well, now," Grampa protested, "I got a little put away yet. You'll be sorry when I'm dead and gone."

"You're never going to die, Grampa," Joyce said harshly. "Just before we left, you bought a hundred-year contract with that Life-Begins-At-Ninety longevity company."

"Well, now," said Grampa, blinking, "how'd you find out about that? Well, now!" In confusion, he turned back to the pircuit and jabbed a button. Thirteen slim lights sprang on. "I'll get you this time!"

Four stretched and stood up. He looked curiously into the corner by the computer where Grampa's chair stood. "You brought that pircuit from Earth, didn't you? What's the game?"

Grampa looked up, obviously relieved to drop his act of intense concentration. "I'll tell you, boy. You play against the pircuit, taking turns, and you can put out one, two or three lights. The player who makes the other one turn out the last light is the winner."

"That's simple," Four said without hesitation. "The winning strategy is to—"

"Don't be a kibitzer!" Grampa snapped. "When I need help, I'll ask for it. No dad-blamed machine is gonna outthink Grampa!" He snorted indignantly.

Four shrugged his narrow shoulders and wandered to the view screen. Within it was the green horizon, curving noticeably. Four angled the picture in toward the ship, sweeping through green, peaceful woodland and plain and blue lake until he stared down into the meadow at the flivver's stern.

"Look!" he said suddenly. "This planet not only has flora—it has fauna." He rushed to the air lock.

"Four!" Reba called out warningly.

"It's all right, Reba," Four assured her. "The air is within one per cent of Earth-normal and the bio-analyzer can find no micro-organisms viable within the Terran spectrum."

"What about macro-organisms—" Reba began, but the boy was gone already. Reba's face was troubled. "That boy!" she said to Junior. "Sometimes I think we've made a terrible mistake with him. He should have friends, play-mates. He's more like a little old man than a boy."

But Junior nodded meaningfully at Fred and disappeared into the chart room. Fred followed casually. Then, as the door slid shut behind him, he asked impatiently. "Well, what's all the mystery?"

"No use bothering the others yet," Junior said, his face puzzled. "You see, I didn't let the flivver drop those last few inches. The polarizer quit."


"That's not the worst. I tried to take it up again. The flivver—it won't budge!"

The thing was a featureless blob, a two-foot sphere of raspberry gelatin, but it was alive. It rocked back and forth in front of Four. It opened a raspberry-color pseudo-mouth and said plaintively, "Fweep? Fweep?"

Joyce drew her chair farther back toward the wall, revulsion on her face. "Four! Get that nasty thing out of here!"

"You mean Fweep?" Four asked in astonishment.

"I mean that thing, whatever you call it." Joyce fluttered her hand impatiently. "Get it out!"

Four's eyes widened farther. "But Fweep's my friend."

"Nonsense!" Joyce said sharply. "Earthmen don't make friends with aliens. And that's nothing but a—a blob!"

"Fweep?" queried the raspberry lips. "Fweep?"

"If it's Four's friend," Reba said firmly, "it can stay. If you don't like to be around it, Grammy, you can always go to your own room."

Joyce stood up indignantly. "Well! And don't call me 'Grammy!' It makes me sound as old as that old goat over there!" She glared malignantly at Grampa. "If you'd rather have that blob than me—well!" She swept grandly out of the central cabin and into one of the private rooms that opened out from it.

"Fweep?" asked the blob.

"Sure," Four said. "Go ahead, fweep—I mean sweep."

Swiftly the sphere rolled across the floor. Behind it was left a narrow path of sparkling clean tile.

Grampa glanced warily at Joyce's door to make sure it was completely closed and then cocked a white eyebrow at Reba. "Good for you, Reba!" he said admiringly. "For forty years now, I've wanted to do that. Never had the nerve."

"Why, thanks, Grampa," Reba said, surprised.

"I like you, gal. Never forget it."

"I like you, too, Grampa. If you'd been a few years younger, Junior would have had competition!"

"You bet he would!" Grampa leaned back and cackled. Then he leaned over confidentially toward Reba and whispered, "Beats me why you ever married a jerk like Junior, anyhow."

Reba looked thoughtfully toward the airlock door. "Maybe I saw something in him nobody else saw, the man he might become. He's been submerged in this family too long; he's still a child to all of you and to himself, too." Reba smiled at Grampa brilliantly. "And maybe I thought he might grow into a man like his grandfather."

Grampa turned red and looked quickly toward Four. The boy was staring intently at Fweep. "What you doing, Four?"

"Trying to figure out what Fweep does with the sweepings," Four said absently. "The outer inch or two of his body gets cloudy and then slowly clears. I think I'll try him with a bigger particle."

"That's the idea, Four. You'll be a Peppergrass yet. How about building me a pircuit?"

"You get the other one figured out?"

"It was easy," Grampa said breezily, "once you understood the principle. The player who moved second could always win if he used the right strategy. Dividing the thirteen lights into three sections of four each—"

"That's right," Four agreed. "I can make you a new one by cannibalizing the other pircuit, but I'll need a few extra parts."

Grampa pushed the wall beside his chair and a drawer slid out of it.

Inside were row after row of nipple-topped, flat-sided, flexible free-fall bottles and a battered cigar box. "Thought you'd say that," he said, picking out the box. "Help yourself." With the other hand, he lifted out one of the bottles and took a long drag on it. "Ahhh!" he sighed, wiped his mouth with the back of his hand, and carefully put the bottle away.

"What is that stuff you drink, Grampa?" Four asked.

"Tonic, boy. Keeps me young and frisky. Now about that pircuit—"

"Did you ever work on Niccolò Tartaglia's puzzle about the three lovely brides, the three jealous husbands, the river and the two-passenger rowboat?"

"Yep," Grampa said. "Too easy."

Four thought a moment. "There's a modern variation with three missionaries and three cannibals. Same river, same rowboat and only one of the cannibals can row. If the cannibals outnumber the missionaries—"

"Sounds good, boy," Grampa said eagerly. "Whip it up for me."

"Okay, Grampa." Four looked at Fweep again. The translucent sphere had paused at Grampa's feet.

Grampa reached down to pat it. For an instant, his hand disappeared into Fweep, and then the alien creature rolled away. This time its path seemed crooked.

Its gelatinous form jiggled. "Hic!" it said.

As if in response, the flivver vibrated. Grampa looked querulously toward the airlock. "Flivver shouldn't shake like that. Not with the polarizer turned on."

The airlock door swung inward. Through the oval doorway walked Fred, followed closely by Junior. They were sweat-stained and weary, scintillation counters dangling heavily from their belts.

"Any luck?" Reba asked brightly.

"Do we look it?" Junior grumbled.

"Where's Joyce?" asked Fred. "Might as well get everybody in on this at once. Joyce!"

The door to his wife's room opened instantly. Behind it, Joyce was regal and slim. The pose was spoiled immediately by her avid question: "Any uranium? Radium? Thorium?"

"No," Fred said slowly, "and no other heavy metals, either. There's a few low-grade iron deposits and that's it."

"Then what makes this planet so heavy?" Reba asked.

Junior shrugged helplessly and collapsed into a chair. "Your guess is as good as anybody's."

"Then we've wasted another week on a worthless rock," Joyce complained. She turned savagely on Fred. "This was going to make us all filthy rich. We were going to find radioactives and retire to Earth like billionaires. And all we've done is spent a year of our lives in this cramped old flivver—and we don't have many of them to spare!" She glared venomously at Grampa.

"We've still got Fweepland," Four said solemnly.

"Fweepland?" Reba repeated.

"This planet. It's not big, but it's fertile and it's harmless. As real estate, it's worth almost as much as if it were solid uranium."

"A good thing, too," Junior said glumly, "because this looks like the end of our search. Short of a miracle, we'll spend the rest of our lives right here—involuntary colonists."

Joyce spun on him. "You're joking!" she screeched.

"I wish I were," Junior said. "But the polarizer won't work. Either it's broken or there's something about the gravity around here that just won't polarize."

"It's these '23 models," Grampa put in disgustedly. "They never were any good."

The land of the Fweep turned slowly on its axis. The orange sun set and rose again and stared down once more at the meadow where the improbable spaceship rested on its improbable stern. The sixteen Earth hours that the rotation had taken had changed nothing inside the ship, either.

Grampa looked up from his pircuit and said, "If I were you, Junior, I would take a good look at the TV repairman when we get back to Earth. If we get back to Earth," he amended. "You can't be Four's father. All over the Universe, gravity is the same, and if it's gravity, the polarizer will polarize it."

"That's just supposition," Junior said stubbornly. "The fact is, it isn't because it doesn't. Q.E.D."

"Maybe the polarizer is broken," Fred suggested.

Grampa snorted. "Broken-shmoken. Nothing to break, Young Fred. Just a few coils of copper wire and they're all right. We checked. We know the power plant is working: the lights are on, the air and water recirculation systems are going, the food resynthesizer is okay. And, anyway, the polarizer could work from the storage battery if it had to."

"Then it goes deeper," Junior insisted. "It goes right to the principle of polarization itself. For some reason, it doesn't work here. Why? Before we can discover the answer to that, we'll have to know more about polarization itself. How does it work, Grampa?"

Grampa gave him a sarcastic grin. "Now you're curious, eh? Couldn't be bothered with Grampa's invention before. Oh, no! Too busy. Accept without question the blessings that the Good Lord provideth—"

"Let's not get up on any pulpits," Fred growled. "Come on, Grampa, what's the theory behind polarization?"

Grampa looked at the four faces staring at him hopefully and the jeering grin turned to a smile. "Well," he said, "at last. You know how light is polarized, eh?" The smile faded. "No, I guess you don't."

He cleared his throat professorially. "Well, now, in ordinary light the vibrations are perpendicular to the ray in all directions. When light is polarized by passing through crystals or by reflection or refraction at non-metallic surfaces, the paths of the vibrations are still perpendicular to the ray, but they're in straight lines, circles or ellipses."

The faces were still blank and unillumined.

"Gravity is similar to light," he pressed on. "In the absence of matter, gravity is non-polarized. Matter polarizes gravity in a circle around itself. That's how we've always known it until the invention of spaceships and later the polarizer. The polarizer polarizes gravity into a straight line. That makes the ship take off and continue accelerating until the polarizer is shut off or its angle is shifted."

The faces looked at him silently. Finally Joyce could endure it no longer. "That's just nonsense! You all know it. Grampa's no genius. He's just a tinkerer. One day he happened to tinker out the polarizer. He doesn't know how it works any more than I do."

"Now wait a minute!" Grampa protested. "That's not fair. Maybe I didn't figure out the theory myself, but I read everything the scientists ever wrote about it. Wanted to know myself what made the blamed thing work. What I told you is what the scientists said, near as I remember. Now me—I'm like Edison. I do it and let everybody else worry over 'why.'"

"The only thing you ever did was the polarizer," Joyce snapped. "And then you spent everything you got from it on those fool perpetual-motion machines and those crazy longevity schemes when any moron would know they were impossible."

Grampa squinted at her sagely. "That's what they said about the gravity polarizer before I invented it."

"But you don't really know why it works," Junior persisted.

"Well, no," Grampa admitted. "Actually I was just fiddling around with some coils when one of them took off. Went right through the ceiling, dragging a battery behind it. I guess it's still going. Ought to be out near the Horsehead Nebula by now. Luckily, I remembered how I'd wound it."

"Why won't the ship work then, if you know so much?" Joyce demanded ironically.

"Well, now," Grampa said in bafflement, "it rightly should, you know."

"We're stuck," Reba said softly. "We might as well admit it. All we can do is set the transmitter to send out an automatic distress call—"

"Which," Joyce interrupted, "might get picked up in a few centuries."

"And make the best of what we've got," Reba went on, unheeding. "If we look at it the right way, it's quite a lot. A beautiful, fertile world. Earth gravity. The flivver—even if the polarizer won't work, there's the resynthesizer; it will keep us in food and clothes for years. By then, we should have a good-sized community built up, because out here we won't have to stop with one child. We can have all the babies we want."

"You know the law: one child per couple," Joyce reminded her frigidly. "You can condemn yourself to exile from civilization if you wish. Not me."

Junior frowned at his wife. "I believe you're actually glad it happened."

"I could think of worse things," Reba said.

"I like your spunk, Reb," Grampa muttered.

"Speaking of children," Junior said, "where's Four?"

"Here." Four came through the airlock and trudged across the room, carrying a curious contraption made of tripod legs supporting a small box from which dangled a plumb bob. Behind Four, like a round, raspberry shadow, rolled Fweep.

"Fweep?" it queried hopefully.

"Not now," said Four.

"Where've you been?" Reba asked anxiously. "What've you been doing?"

"I've been all over Fweepland," Four said wearily, "trying to locate its center of gravity."

"Well?" Fred prompted.

"It shifts."

"That's impossible," said Junior.

"Not for Fweep," Four replied.

"What do you mean by that?" Joyce suspiciously asked.

"It shifted," Four explained patiently, "because Fweep kept following me."

"Fweep?" Junior repeated stupidly.

"Fweep?" Fweep said eagerly.

"He's why the flivver won't work. What Grampa invented was a linear polarizer. Fweep is a circular polarizer. He's what makes this planet so heavy. He's why we can't leave."

The land of the Fweep rotated once on its axis, and Grampa lowered the nippled bottle from his lips. He sighed. "I got it figured out, Four," he said, holding out the pircuit proudly. "A missionary takes over a non-rowing type cannibal, leaves him there, and then the rowing cannibal takes over the other cannibal and leaves him there and—"

"Not now, Grampa," Four said inattentively as he watched Fweep making the grand tour of the cabin.

The raspberry sphere swept over a scattering of crumbs, engulfed them, absorbed them. Four looked at Joyce. Joyce was watching Fweep, too.

"Rat poison?" Four asked.

Joyce started guiltily. "How did you know?"

"There's no use trying to poison Fweep," Four said calmly. "He's got no enzymes to act on, no nervous system to paralyze. He doesn't even use what he 'eats' on a molecular level at all."

"What level does he use?" Junior wanted to know.

"Point the scintillation counter at him."

Junior dug one of the counters out of the supply cabinet and aimed the pickup at Fweep. The counter began to hum. As Fweep approached, the hum rose in pitch. As it passed, the hum dropped.

Junior looked at the counter's dial. "He's radioactive, all right. Not much, but enough. But where does he get the radioactive material?"

"He uses ordinary matter," Four said. "He must have used up the few deposits of natural radioactives a long time ago."

"He uses ordinary substances on an atomic level?" Junior said unbelievingly.

Four nodded. "And that 'skin' of his—whatever it is he uses for skin—is more efficient in stopping particle emissions than several feet of lead."

Fred studied Fweep thoughtfully. "Maybe we could feed him enough enriched uranium from the pile to put him over the critical mass."

"And blow him up? I don't think it's possible, but even if it were, it might be a trifle more than disastrous for us." Four giggled at the thought.

Joyce glared at him furiously. "Four! Act your age! We've got to do something with him. It's preposterous that we should be detained here at the whim of a mere blob!"

"I don't figure it's a whim," Grampa said. "Circular gravity is what he's got to have for one reason or another, so he just naturally bends the space-time continuum around him—conscious or subconscious, I don't know. But protoplasm is always more efficient than machines, so the flivver won't move."

"I don't care why that thing does it," Joyce said icily. "I want it stopped, and the sooner the better. If it won't turn the gravity off, we'll just have to do away with it."

"How?" asked Four. "Fweep's skin is pretty close to impervious and you can't shoot him, stab him or poison him. He doesn't breathe, so you can't drown or strangle him. You can't imprison him; he 'eats' everything. And violence might be more dangerous to us than to him. Right now, Fweep is friendly, but suppose he got mad! He could lower his radioactive shield or he might increase the gravity by a few times. Either way, you'd feel rather uncomfortable, Grammy."

"Don't call me 'Grammy!' Well, what are we going to do, just sit around and wait for that thing to die?"

"We'd have a long wait," Four observed. "Fweep is the only one of his kind on this planet."


"Probably he's immortal."

"And he doesn't reproduce?" Reba asked sympathetically.

"Probably not. If he doesn't die, there's no point in reproduction. Reproduction is nature's way of providing racial immortality to mortal creatures."

"But he must have some way of reproduction," Reba argued. "An egg or something. He couldn't just have sprung into being as he is now."

"Maybe he developed," Four offered. "It seems to me that he's bigger than when we first landed." "He must have been here a long, long time," Fred said. "Fweepland, as Four calls it, kept its atmosphere and its water, which a planet this size ordinarily would have lost by now."

Reba looked at Fweep kindly. "We can thank the little fellow for that, anyway."

"I thank him for nothing," Joyce snapped. "He lured us down here by making us think the planet had heavy metals and I want him to let us go immediately!"

Fred turned impatiently on his wife. "Well, try making him understand! And if you can make him understand what you want him to do, try making him do it!"

Joyce looked at Fred with startled eyes. "Fred!" she said in a high, shocked voice and turned blindly toward her room.

Grampa lowered his bottle and smacked his lips. "Well, boy," he said to Fred, "I thought you'd never do that. Didn't think you had it in you."

Fred stood up apologetically. "I'd better go calm her down," he muttered, and walked quickly after Joyce.

"Give her one for me!" Grampa called.

Fred's shoulders twitched as the door closed behind him. From the room came the filtered sound of high-pitched voices rising and falling like some reedy folk music.

"Makes you think, doesn't it?" Grampa said, looking at Fweep benignly. "Maybe the whole theory of gravitation is cockeyed. Maybe there's a Fweep for every planet and sun, big and little, polarizing the gravity in circles, and the matter business is not a cause but a result."

"What I can't understand," Junior said thoughtfully, "is why the polarizer worked for a little while when we landed—long enough to keep us from being squashed—and then quit."

"Fweep didn't recognize it immediately, didn't know what it was or where it came from," Four explained. "All he knew was he didn't like linear polarization and he neutralized it as soon as he could. That's when we dropped."

"Linear polarization is uncomfortable for him, is it?" Grampa said. "Makes you wonder how something like Fweep could ever develop."

"He's no more improbable than people," said Four.

"Less than some I've known," Grampa conceded.

"If he can eat anything," Reba said, "why does he keep sweeping the cabin for dust and lint?"

"He wants to be helpful," Four replied without hesitation, "and he's lonely. After all," he added wistfully, "he's never had any friends."

"How do you know all these things?" Joyce asked from her doorway, excitement in her voice. "Can you talk to it?"

Behind her, Fred said, "Now, Joyce, you promised—"

"But this is important," Joyce cut him off eagerly. "Can you? Talk to it, I mean?"

"Some," Four admitted.

"Have you asked it to let us go?"


"Well? What did it say?"

"He said he didn't want his friend to leave him."

At the word, Fweep rolled swiftly across the floor and bounced into Four's lap. It nestled against him lovingly and opened raspberry lips. "Fwiend," it said.

"Well, now," Grampa said maliciously, his eye on Joyce, "that's no problem. We can just leave Four here with Fweep."

In a voice filled with sanctimonious concern, Joyce said, "That's quite a sacrifice to ask, but—"

"Joyce!" Reba cried, horrified. "Grampa was joking, but you actually mean it. Four is only a baby and yet you'd let him—"

"Never mind, Reba," Four said evenly. "It was just what I was going to suggest myself. It's the one really logical solution."

"Fwiend," said Fweep gently.

The land of the Fweep turned like a fat old man toasting himself in front of an open fire, and Junior sat at the computer's keyboard swearing in a steady monotone.

"Junior!" said Joyce, shocked.

Junior swung around impatiently. "Sorry, Mother, but this damned thing won't work."

"I'm sure that calling it names won't help, and besides, you shouldn't expect a machine to do something that we can't do. And if it did work, it would only say that the logical answer is the one I sug—"

"Mother!" Junior warned. "We decided not to talk about it any more. Four is strange enough without encouraging him to think like a martyr. It's out of the question. If that's the only way we can leave this planet, we'll stay here until Four has a beard as white as Grampa's!"

"Well!" Joyce said in a stiff, offended tone and sat back in her chair.

Grampa lowered the nippled bottle from his lips and chortled. "Junior, I apologize for all the mean things I ever said about you. Maybe you got the makings of a Peppergrass yet."

Junior turned back to the keyboard and studied it, his chin in his hand. "It's just a matter of stating the problem in terms the computer can work on."

"I take it all back," said Grampa. "That computer won't help you with this problem, Junior. This ain't a long, complicated calculation; it's a simple problem in logic. It's a pircuit problem, like the one about the cannibals and the missionaries. We can't leave Fweepland because Fweep won't let our polarizer work. He won't let our polarizer work because he doesn't like gravity that's polarized in a straight line, and he don't want Four to leave him.

"Now Fweep ain't the brightest creature in the Universe, so he can't understand why we're so gosh-fired eager to leave. And as long as he's got Four, he's happy. Why should he make himself unhappy? As a favor to Four, he'd let us leave—if we'd leave Four here with him, which we ain't gonna do.

"That's the problem. All we got to do is figure out the answer. No use making a pircuit, because a puzzle circuit is just a miniature computer with the solution built in; if you can build the pircuit, you've already solved the problem. And if you can state the problem to Abacus, you've already got the answer. All you want from it then is decimal points."

"That may be," Junior said stubbornly, "but I still want to know why this computer won't work. It won't even do simple arithmetic! Where's Four? He's the only one who understands this thing."

"He's outside, playing in the meadow with Fweep," Reba said, her voice soft. "No, here they come now."

Through the airlock came Four, carrying Fweep on his shoulder like a raspberry cat without head or tail. Four's thin face glowed with exertion and glistened with sweat. Already the orange sun had begun to paint his skin tan.

"We've been playing dodge ball," Four panted. "Fweep was the ball and I had to dodge him."

"There's something wrong with this computer," Junior complained. "Take a look at it."

"Sure, Daddy," Four said promptly, and he took his father's place at the keyboard. After a few moments, he began to frown, then detached a front panel. He started sorting through the maze of wires and electronic components.

Grampa watched him with a wary eye.

Joyce was unable to restrain herself any longer. "The way you people talk, a person would think we were never going to leave this godforsaken, miserable, uncivilized planet."

"That seems to be the general idea," Grampa chuckled, enjoying her dismay.

"Unless we can build a reaction rocket ship to push us out of Fweep's range," Fred said glumly.

"We've got the iron ore!" Junior put in eagerly.

Grampa snorted. "Come on, use your brains. You'd have to build a ship; these flivvers weren't built for the stresses of reaction flight. By the time you've solved all the problems of motors and alloys and rocket-tube linings, fuel, ship construction, personnel protection, and all the rest of it, this planet would be another Detroit and your great-great-great-grandchildren would be living in it. You couldn't build a blast furnace even if you had the complete Congressional microfilm library! You'd do better trying to figure out how Fweep does what he does and doing some practicing on that."

"Well," Junior said peevishly, "trying to get away is better than sitting here talking about it."

Reba stared thoughtfully at Junior and said, "Maybe Fweep would go with us."

"Yes!" Joyce said excitedly. "Maybe the dear little thing would go with us. That would solve everything!"

Without looking around, Four said, "I asked him already. Fweep's afraid to come along."

"I'm sure we would be very good to him," Joyce said swiftly. "I've always liked pets. Why, I once had a goldfish of my very own!"

"Which you let die," Fred said dryly, "because you forgot to feed it."

"Oh, he's not afraid of people," Four told them. "He's afraid of space and unpolarized gravity and things like that. He's lived here all his life—that's a long time—and it makes him feel awful funny just to think about leaving. He says he can still remember the way our linear gravitation felt inside when we landed."

"Well," Joyce said firmly, "he'll just have to fight it, that's all. If a person let that kind of neurotic impulse rule his life, he'd be completely demoralized in no time."

Four glanced over his shoulder at Joyce, as if to see if she were joking. Shaking his head, he returned to the computer's innards. A moment later, he swung around and stared accusingly at Grampa. "You've cannibalized Abacus!"

"Well, now," Grampa protested, licking his lips nervously. "You see, I—"

"That's where you got the parts for the pircuits!" Four said with merciless logic.

Joyce stood up virtuously and shook her finger at Grampa. "First you entice us out here in this nasty old flivver; then you get us stuck; and now you've ruined the computer for your nasty old games!"

"Well, now," Grampa blustered, "the goldarn thing wouldn't work, would it? We didn't need it—not with Four around. He figures everything out in his head and we just used Abacus to sort of check him. Ain't that right now?"

Five pairs of eyes stared at him in silence.

"Well, now," Grampa said defensively, "I got it all worked out anyhow. We can leave here any time we get ready."

The land of the Fweep turned and grew small in the view screen, and Junior sat in the pilot's chair, his hand on the control stick, his eyes fixed on the moving dials in front of him.

There were three others in the room: Reba, who looked at the dwindling Fweepland and sighed; Joyce, who sat tautly in her chair, her face fixed and unbelieving; and Fred, who looked at Joyce and shook his head.

Grampa opened the door to his room and stepped cockily into the central cabin, shutting the door behind him. "Well?" he demanded confidently. "Are we heading for Earth?"

Junior gestured toward the screen. "If Four's coordinates are right."

"Speaking of coordinates," Grampa said briskly, "make sure we got the coordinates of Fweepland. It'll take a long time for that atmosphere to dissipate. A nice little world like that is worth its weight in uranium to a good real estate salesman."

"How did you do it?" Joyce challenged.

Grampa slapped her familiarly on the shoulder. "A problem of gravity," he said gayly, "but a simple one. Nothing for an old pircuit man like me. I guess you folks won't laugh at Grampa and his pircuits any more. Not only did Grampa get you out of Fweepland, but he's taking you back with a valuable little subdivision in the third quadrant to file on."

"I hate to spoil the party," Fred said, "but have you thought about what you're going to do with Fweep?"

"Fweep?" Grampa repeated, puzzled. "Why should I do anything with Fweep?"

"We can't take him back to Earth with us."

"Why not?" Grampa demanded.

"In the first place, the Immigration Authority would have to pass on him. That might take years, with Fweep's powers and abilities. More important, if Fweep got loose on Earth, every flivver would have the same problem there that we had here. And next time Fweep might not be so cooperative. I don't know what you did to Fweep in there, but if he's still alive, the I.A. isn't going to take a chance."

Grampa considered the prospect without dismay. "I wonder if we could smuggle him in. With all those flivvers not working, they'd have to pay us before they could take off."

"Grampa!" Fred said sternly. "That would be blackmail—or worse. Besides getting in trouble with the I.A., you'd get it from the W.B.I. and the I.C.C."

Grampa waved his hand impatiently. "We'll solve that problem when we come to it. After all, an old pircuit man like me—"

"What did you do to Fweep?" Joyce repeated insistently.

Grampa cleared his throat with pride. "Well, now, I'll tell you. I just happened to notice that Fweep liked my tonic. Every time I took a little nip, the little beast was around my chair, trying to clean my hand for me."

"Tonic!" Joyce sniffed. "Liquor, you mean!"

"Now that's not right," Grampa objected. "I said tonic and I mean tonic. Got a little alcohol in it for a preservative, maybe, but the important part is the minerals. That's the Longevity Institute's secret. It's what keeps me young. Want a little nip?" He leered at Joyce.

"You mean you got Fweep drunk?" Fred exclaimed.

"Well, now, that was the effect, but I can't swear it was the alcohol. Not unless Fweep can use the stuff on the molecular level if he wants. On the other hand, maybe it was the minerals in there that affected him. Little world like Fweepland, maybe it lacked a few things when it was made. But the way I looked at it, it stood to reason the little fellow could use a drink. Alone all these centuries, he must've got pretty dry. But whatever it was, he sure got high. Lost all control."

"Poor Fweep," Reba murmured.

"Poor nothing," Grampa said. "He was the happiest little critter I ever saw. When Four explained to him just what we wanted, he went right to work on that bottle and—"

Gramp's door swung open once more. "Grampa! Grampa!" Four shouted. "Fweep! He—I mean—well, we've been calling him by the wrong pronoun. Look!"

Four came running out of the room. Behind him rolled a tiny raspberry sphere about the size of a marble. Occasionally it hopped in the air and said, "Fweep?" in a small, high voice.

Behind it rolled and hopped a second raspberry marble. "Fweep?" it said. Behind it came another and another until the cabin was full of them, rolling, bouncing, calling "Fweep?"

Dazedly, Junior counted them. "One hundred and one, one hundred and two, one hundred and—"

"Oh, Junior," Reba said, hugging him excitedly. "Aren't they cute?"

"What happened?" Grampa asked, as dazed as Junior.

"Maybe it was the tonic," Four said, "but I suspect it was the the unpolarized gravity. All of a sudden, Fweep started splitting like an amoeba, over and over. Do you suppose that was what made him nervous?"

"That's the way the little fellow reproduces, all right," said Grampa. "I wonder if he has to wait until a race becomes civilized enough to discover the polarizer, eh?"

"Ugh!" gasped Joyce, brushing a Fweep out of her lap.

Grampa looked at the cabin and its occupants happily.

"I'd like to remind you," Fred said gravely, "that this multiplies our problem of what to do with Fweep over one hundred times."

"What problem?" asked Grampa. "The only problem we got is how we're gonna spend the cash. We're in business—the gravity business. We'll call it Gravity, Incorporated, and we can reclaim every little hunk of rock in the Solar System. Each one of those little fellows is worth a fortune! We'll give the satellites and the asteroids Earth-normal gravities and atmospheres and, by golly, we're rich!"

"Rich?" Joyce echoed. A smile slowly replaced the expression of distaste. She snapped her fingers. "Here, Fweepie," she said in her most enticing tone. "Here, little darlings! Come to dear Joyce!"

But they had all hopped to Four and were clustered around him like a raspberry bubble bath. Through them, his face peered, thin and happy.

Grampa looked at Reba. She was hugging Junior happily and smiling at Four. Grampa looked back at the boy.

"We'll have to be exclusive, though," Grampa said. "Considering the Fweeps' likes and dislikes, that is. We'll sell only to people with children."
