Exploration Team

Murray Leinster

The nearer moon went by overhead. It was jagged and irregular in shape, probably a captured asteroid. Huyghens had seen it often enough, so he did not go out of his quarters to watch it hurtle across the sky with seemingly the speed of an atmosphere-flier, occulting the stars as it went. Instead, he sweated over paperwork, which should have been odd because he was technically a felon and all his labors on Loren II felonious. It was odd, too, for a man to do paperwork in a room with steel shutters and a huge bald eagle—untethered—dozing on a three-inch perch set in the wall. But paperwork was not Huyghens' real task. His only assistant had tangled with a night-walker, and the furtive Kodius Company ships had taken him away to where Kodius Company ships came from. Huyghens had to do two men's work in loneliness. To his knowledge, he was the only man in this solar system.

Below him, there were snufflings. Sitka Pete got up heavily and padded to his water pan. He lapped the refrigerated water and sneezed. Sourdough Charley waked and complained in a rumbling growl. There were divers other rumblings and mutterings below. Huyghens called reassuringly, "Easy there!" and went on with his work. He finished a climate report, and fed figures to a computer. While it hummed over them he entered the inventory totals in the station log, showing what supplies remained. Then he began to write up the log proper.

"Sitka Peter," he wrote, "has apparently solved the problem of killing individual sphexes. He has learned that it doesn't do to hug them and that his claws can't penetrate their hide, not the top-hide, anyhow. Today Semper notified us that a pack of sphexes had found the scent-trail to the station. Sitka hid downwind until they arrived. Then he charged from the rear and brought his paws together on both sides of a sphex's head in a terrific pair of slaps. It must have been like two twelve-inch shells arriving from opposite directions at the same time. It must have scrambled the sphex's brains as if they were eggs. It dropped dead. He killed two more with such mighty pairs of wallops. Sourdough Charley watched, grunting, and when the sphexes turned on Sitka, he charged in his turn. I, of course, couldn't shoot too close to him, so he might have fared badly except that Faro Nell came pouring out of the bear-quarters to help. The diversion enabled Sitka Pete to resume the use of his new technique, towering on his hind legs and swinging his paws in the new and grizzly fashion. The fight ended promptly. Semper flew and screamed above the scrap, but as usual did not join in. Note: Nugget, the cub, tried to mix in but his mother cuffed him out of the way. Sourdough and Sitka ignored him as usual. Kodius Champion's genes are sound!"

The noises of the night went on outside. There were notes like organ-tones—song-lizards. There were the tittering, giggling cries of night-walkers. There were sounds like jack-hammers, and doors closing, and from every direction came noises like hiccoughs in various keys. These were made by the improbable small creatures which on Loren II took the place of insects.

Huyghens wrote out:

"Sitka seemed ruffled when the fight was over. He used his trick on the head of every dead or wounded sphex, except those he'd killed with it, lifting up their heads for his pile-driver-like blows from two directions at once, as if to show Sourdough how it was done. There was much grunting as they hauled the carcasses to the incinerator. It almost seemed—"

The arrival-bell clanged, and Huyghens jerked up his head to stare at it. Semper, the eagle, opened icy eyes. He blinked. Noises. There was a long, deep, contented snore from below. Something shrieked, out in the jungle. Hiccoughs, clatterings, and organ-notes . . .

The bell clanged again. It was a notice that an unscheduled ship aloft somewhere had picked up the beacon-beam—which only Kodius Company ships should know about—and was communicating for a landing. But there shouldn't be any ships in this solar system just now! The Kodius Company's colony was completely illegal, and there were few graver crimes than unauthorized occupation of a new planet.

The bell clanged a third time. Huyghens swore. His hand went out to cut off the beacon, and then stopped. That would be useless. Radar would have fixed it and tied it in with physical features like the nearby sea and the Sere Plateau. The ship could find the place, anyhow, and descend by daylight.

"The devil!" said Huyghens. But he waited yet again for the bell to ring. A Kodius Company ship would double-ring to reassure him. But there shouldn't be a Kodius Company ship for months.

The bell clanged singly. The space-phone dial flickered and a voice came out of it, tinny from stratospheric distortion: "Calling ground. Calling ground. Crete Line ship Odysseus calling ground on Loren II. Landing one passenger by boat. Put on your field lights."

Huyghens' mouth dropped open. A Kodius Company ship would be welcome. A Colonial Survey ship would be extremely unwelcome, because it would destroy the colony and Sitka and Sourdough and Faro Nell and Nugget—and Semper—and carry Huyghens off to be tried for unauthorized colonization and all that it implied.

But a commercial ship, landing one passenger by boat . . . There were simply no circumstances under which that could happen. Not to an unknown, illegal colony. Not to a furtive station!

Huyghens flicked on the landing-field lights. He saw the glare over the field half a mile away. Then he stood up and prepared to take the measures required by discovery. He packed the paperwork he'd been doing into the disposal-safe. He gathered up all personal documents and tossed them in. Every record, every bit of evidence that the Kodius Company maintained this station went into the safe. He slammed the door. He moved his finger toward the disposal-button, which would destroy the contents and melt down even the ashes past their possible use for evidence in court.

Then he hesitated. If it were a Survey ship, the button had to be pressed and he must resign himself to a long term in prison. But a Crete Line ship—if the space-phone told the truth—was not threatening. It was simply unbelievable.

He shook his head. He got into travel garb, armed himself, and went down into the bear-quarters, turning on lights as he went. There were startled snufflings, and Sitka Pete reared himself to a sitting position to blink at him. Sourdough Charley lay on his back with his legs in the air. He'd found it cooler, sleeping that way. He rolled over with a thump, and made snorting sounds which somehow sounded cordial. Faro Nell padded to the door of her separate apartment, assigned her so that Nugget would not be underfoot to irritate the big males.

Huyghens, as the human population of Loren II, faced the work-force, fighting-force, and—with Nugget—four-fifths of the terrestrial non-human population of the planet. They were mutated Kodiak bears, descendants of that Kodius Champion for whom the Kodius Company was named. Sitka Pete was a good twenty-two hundred pounds of lumbering, intelligent carnivore, Sourdough Charley would weigh within a hundred pounds of that figure. Faro Nell was eighteen hundred pounds of female charm and ferocity. Then Nugget poked his muzzle around his mother's furry rump to see what was toward, and he was six hundred pounds of ursine infancy. The animals looked at Huyghens expectantly. If he'd had Semper riding on his shoulder they'd have known what was expected of them.

"Let's go," said Huyghens. "It's dark outside, but somebody's coming. And it may be bad!"

He unfastened the outer door of the bear-quarters. Sitka Pete went charging clumsily through it. A forthright charge was the best way to develop any situation—if one was an oversize male Kodiak bear. Sourdough went lumbering after him. There was nothing hostile immediately outside. Sitka stood up on his hind legs—he reared up a solid twelve feet—and sniffed the air. Sourdough methodically lumbered to one side and then the other, sniffing in his turn. Nell came out, nine-tenths of a ton of daintiness, and rumbled admonitorily at Nugget, who trailed her closely. Huyghens stood in the doorway, his night-sighted gun ready. He felt uncomfortable at sending the bears ahead into a Loren II jungle at night, but they were qualified to scent danger, and he was not.

The illumination of the jungle in a wide path toward the landing-field made for weirdness in the look of things. There were arching giant ferns and columnar trees which grew above them, and the extraordinary lanceolate underbrush of the jungle. The flood-lamps, set level with the ground, lighted everything from below. The foliage, then, was brightly lit against the black night-sky, brightly enough lit to dim the stars.

"On ahead!" commanded Huyghens, waving. "Hup!"

He swung the bear-quarters door shut, and moved toward the landing-field through the lane of lighted forest. The two giant male Kodiaks lumbered ahead. Sitka Pete dropped to all fours and prowled. Sourdough Charley followed closely, swinging from side to side. Huyghens came behind the two of them, and Faro Nell brought up the rear with Nugget nudging her.

It was an excellent military formation for progress through dangerous jungle. Sourdough and Sitka were advance guard and point, respectively, while Faro Nell guarded the rear. With Nugget to look after, she was especially alert against attack from behind. Huyghens was, of course, the striking force. His gun fired explosive bullets which would discourage even sphexes, and his night-sight—a cone of light which went on when he took up the trigger-slack—told exactly where they would strike. It was not a sportsmanlike weapon, but the creatures of Loren II were not sportsmanlike antagonists. The night-walkers, for example. But night-walkers feared light. They attacked only in a species of hysteria if it were too bright.

Huyghens moved toward the glare at the landing field. His mental state was savage. The Kodius Company on Loren II was completely illegal. It happened to be necessary, from one point of view, but it was still illegal. The tinny voice on the space-phone was not convincing, in ignoring that illegality. But if a ship landed, Huyghens could get back to the station before men could follow, and he'd have the disposal-safe turned on in time to protect those who'd sent him here.

Then he heard the far-away and high harsh roar of a landing boat rocket—not a ship's bellowing tubes—as he made his way through the unreal-seeming brush. The roar grew louder as he pushed on, the three big Kodiaks padding here and there, sniffing for danger.

He reached the edge of the landing field, and it was blindingly bright, with the customary divergent beams slanting skyward so a ship could check its instrument-landing by sight. Landing fields like this had been standard, once upon a time. Nowadays all developed planets had landing-grids—monstrous structures which drew upon ionospheres for power and lifted and drew down star-ships with remarkable gentleness and unlimited force. This sort of landing field would now be found only where a survey-team was at work, or where some strictly temporary investigation of ecology or bacteriology was under way, or where a newly authorized colony had not yet been able to build its landing-grid. Of course, it was unthinkable that anybody would attempt a settlement in defiance of the law!

Already, as Huyghens reached the edge of the scorched open space, the night-creatures had rushed to the light, like moths on Earth. The air was misty with crazily gyrating, tiny flying things. They were innumerable and of every possible form and size, from the white midges of the night and multi-winged flying worms to those revoltingly naked-looking larger creatures which might have passed for plucked flying monkeys if they had not been carnivorous and worse. The flying things soared and whirred and danced and spun insanely in the glare, making peculiarly plaintive humming noises. They almost formed a lamp-lit ceiling over the cleared space, and actually did hide the stars. Staring upward, Huyghens could just barely make out the blue-white flame of the space-boat's rockets through the fog of wings and bodies.

The rocket-flame grew steadily in size. Once it tilted to adjust the boat's descending course. It went back to normal. A speck of incandescence at first, it grew until it was like a great star, then a more-than-brilliant moon, and then it was a pitiless glaring eye. Huyghens averted his gaze from it. Sitka Pete sat lumpily and blinked at the dark jungle away from the light. Sourdough ignored the deepening, increasing rocket-roar. He sniffed the air. Faro Nell held Nugget firmly under one huge paw and licked his head as if tidying him up to be seen by company. Nugget wriggled.

The roar became that of ten thousand thunders. A warm breeze blew outward from the landing field. The rocket-boat hurtled downward, and as its flame touched the mist of flying things, they shriveled and burned. Then there were churning clouds of dust everywhere, and the center of the field blazed terribly—and something slid down a shaft of fire—squeezed it flat, and sat on it—and the flame went out. The rocket-boat sat there, resting on its tail-fins, pointing toward the stars from which it came.

There was a terrible silence after the tumult. Then, very faintly, the noises of the night came again. There were sounds like those of organ-pipes, and very faint and apologetic noises like hiccoughs. All these sounds increased, and suddenly Huyghens could hear quite normally. As he watched, a side-port opened with a clattering, something unfolded from where it had been inset into the hull of the space-boat, and there was a metal passageway across the flame-heated space on which the boat stood.

A man came out of the port. He reached back in and shook hands. Then he climbed down the ladder-rungs to the walkway, and marched above the steaming baked area, carrying a traveling bag. At the end of the walk he stepped to the ground, and moved hastily to the edge of the clearing. He waved to the space-boat. The walk-way folded briskly back up to the hull and vanished in it, and almost at once a flame exploded into being under the tail-fins. There were fresh clouds of monstrous, choking dust, a brightness like that of a sun, and noise past the possibility of endurance. Then the light rose swiftly through the dust-cloud, sprang higher, and climbed more swiftly still. When Huyghens' ears again permitted him to hear anything, there was only a diminishing mutter in the heavens and a faint bright speck of light ascending to the sky, swinging eastward as it rose to intercept the ship from which it had descended.

The night-noises of the jungle went on, even though there was a spot of incandescence in the day-bright clearing, and steam rolled up in clouds at the edge of the hottest area. Beyond that edge, a man with a traveling bag in his hand looked about him.

Huyghens advanced toward him as the incandescence dimmed. Sourdough and Sitka preceded him. Faro Nell trailed faithfully, keeping a maternal eye on her offspring. The man in the clearing stared at the parade they made. It would be upsetting, even after preparation, to land at night on a strange planet, to have the ship's boat and all links with the rest of the cosmos depart, and then to find oneself approached—it might seem stalked—by two colossal male Kodiak bears, with a third bear and a cub behind them. A single human figure in such company might seem irrelevant.

The new arrival gazed blankly. He moved back a few steps. Then Huyghens called:

"Hello, there! Don't worry about the bears! They're friends!"

Sitka reached the newcomer. He went warily downwind from him and sniffed. The smell was satisfactory. Man-smell. Sitka sat down with the solid impact of more than a ton of bear meat landing on packed dirt, and regarded the man. Sourdough said "Whoosh!" and went on to sample the air beyond the clearing. Huyghens approached. The newcomer wore the uniform of the Colonial Survey. That was bad. It bore the insignia of a senior officer. Worse.

"Hah!" said the just-landed man. "Where are the robots? What in all the nineteen hells are these creatures? Why did you shift your station? I'm Bordman, here to make a progress report on your colony."

Huyghens said:

"What colony?"

"Loren II Robot Installation—" Then Bordman said indignantly, "Don't tell me that that idiot skipper can have dropped me at the wrong place! This is Loren II, isn't it? And this is the landing field. But where are your robots? You should have the beginning of a grid up! What the devil's happened here and what are these beasts?"

Huyghens grimaced.

"This," he said, "is an illegal, unlicensed settlement. I'm a criminal. These beasts are my confederates. If you don't want to associate with criminals you needn't, of course, but I doubt if you'll live till morning unless you accept my hospitality while I think over what to do about your landing. In reason, I ought to shoot you."

Faro Nell came to a halt behind Huyghens, which was her proper post in all out-door movement. Nugget, however, saw a new human. Nugget was a cub, and therefore friendly. He ambled forward. He wriggled bashfully as he approached Bordman. He sneezed, because he was embarrassed.

His mother overtook him and cuffed him to one side. He wailed. The wail of a six-hundred-pound Kodiak bear-cub is a remarkable sound. Bordman gave ground a pace.

"I think," he said carefully, "that we'd better talk things over. But if this is an illegal colony, of course you're under arrest and anything you say will be used against you."

Huyghens grimaced again.

"Right," he said. "But now if you'll walk close to me, we'll head back to the station. I'd have Sourdough carry your bag—he likes to carry things—but he may need his teeth. We've half a mile to travel." He turned to the animals. "Let's go!" he said commandingly. "Back to the station! Hup!"

Grunting, Sitka Peter arose and took up his duties as advanced point of a combat-team. Sourdough trailed, swinging widely to one side and another. Huyghens and Bordman moved together. Faro Nell and Nugget brought up the rear.

There was only one incident on the way back. It was a nightwalker, made hysterical by the lane of light. It poured through the underbrush, uttering cries like maniacal laughter.

Sourdough brought it down, a good ten yards from Huyghens. When it was all over, Nugget bristled up to the dead creature, uttering cub-growls. He feigned to attack it.

His mother whacked him soundly.

There were comfortable, settling-down noises below, as the bears grunted and rumbled, and ultimately were still. The glare from the landing field was gone. The lighted lane through the jungle was dark again. Huyghens ushered the man from the space-boat up into his living quarters. There was a rustling stir, and Semper took his head from under his wing. He stared coldly at the two humans, spread monstrous, seven-foot wings, and fluttered them. He opened his beak and closed it with a snap.

"That's Semper," said Huyghens. "Semper Tyrannis. He's the rest of the terrestrial population here. Not being a fly-by-night sort of creature, he didn't come out to welcome you."

Bordman blinked at the huge bird, perched on a three-inch-thick perch set in the wall.

"An eagle?" he demanded. "Kodiak bears—mutated ones, but still bears—and now an eagle? You've a very nice fighting unit in the bears—"

"They're pack animals too," said Huyghens. "They can carry some hundreds of pounds without losing too much combat efficiency. And there's no problem of supply. They live off the jungle. Not sphexes, though. Nothing will eat a sphex."

He brought out glasses and a bottle and indicated a chair. Bordman put down his traveling bag, took a glass, and sat down.

"I'm curious," he observed. "Why Semper Tyrannis? I can understand Sitka Pete and Sourdough Charley as fighters. But why Semper?"

"He was bred for hawking," said Huyghens. "You sic a dog on something. You sic Semper Tyrannis. He's too big to ride on a hawking-glove, so the shoulders of my coats are padded to let him ride there. He's a flying scout. I've trained him to notify us of sphexes, and in flight he carries a tiny television camera. He's useful, but he hasn't the brains of the bears." Bordman sat down and sipped at his glass.

"Interesting, very interesting! Didn't you say something about shooting me?"

"I'm trying to think of a way out," Huyghens said. "Add up all the penalties for illegal colonization and I'd be in a very bad fix if you got away and reported this set-up. Shooting you would be logical."

"I see that," said Bordman reasonably. "But since the point has come up—I have a blaster trained on you from my pocket."

Huyghens shrugged.

"It's rather likely that my human confederates will be back here before your friends. You'd be in a very tight fix if my friends came back and found you more or less sitting on my corpse."

Bordman nodded.

"That's true, too. Also it's probable that your fellow-terrestrials wouldn't cooperate with me as they have with you. You seem to have the whip hand, even with my blaster trained on you. On the other hand, you could have killed me easily after the boat left, when I'd first landed. I'd have been quite unsuspicious. Therefore you may not really intend to murder me."

Huyghens shrugged again.

"So," said Bordman, "since the secret of getting along with people is that of postponing quarrels, suppose we postpone the question of who kills whom? Frankly, I'm going to send you to prison if I can. Unlawful colonization is very bad business. But I suppose you feel that you have to do something permanent about me. In your place I probably should, too. Shall we declare a truce?"

Huyghens indicated indifference.

"Then I do," Bordman said. "I have to! So—"

He pulled his hand out of his pocket and put a pocket blaster on the table. He leaned back.

"Keep it," said Huyghens. "Loren II isn't a place where you live long unarmed." He turned to a cupboard. "Hungry?"

"I could eat," admitted Bordman.

Huyghens pulled out two meal-packs from the cupboard and inserted them in the readier below. He set out plates.

"Now, what happened to the official, licensed, authorized colony here?" asked Bordman briskly. "License issued eighteen months ago. There was a landing of colonists with a drone-fleet of equipment and supplies. There've been four ship-contacts since. There should be several thousand robots being industrious under adequate human supervision. There should be a hundred-mile-square clearing, planted with food-plants for later human arrivals. There should be a landing-grid at least half-finished. Obviously there should be a space-beacon to guide ships to a landing. There isn't. There's no clearing visible from space. That Crete Line ship has been in orbit for three days, trying to find a place to drop me. Her skipper was fuming. Your beacon is the only one on the planet, and we found it by accident. What happened?"

Huyghens served the food. He said dryly:

"There could be a hundred colonies on this planet without any one knowing of any other. I can only guess about your robots, but I suspect they ran into sphexes."

Bordman paused, with his fork in his hand.

"I read up on this planet, since I was to report on its colony. A sphex is part of the inimical animal life here. Cold-blooded belligerent carnivore, not a lizard but a genus all its own. Hunts in packs. Seven to eight hundred pounds, when adult. Lethally dangerous and simply too numerous to fight. They're why no license was ever granted to human colonists. Only robots could work here, because they're machines. What animal attacks machines?"

Huyghens said:

"What machine attacks animals? The sphexes wouldn't bother robots, of course, but would robots bother the sphexes?" Bordman chewed and swallowed.

"Hold it! I'll agree that you can't make a hunting-robot. A machine can discriminate, but it can't decide. That's why there's no danger of a robot revolt. They can't decide to do something for which they have no instructions. But this colony was planned with full knowledge of what robots can and can't do. As ground was cleared, it was enclosed in an electrified fence which no sphex could touch without frying."

Huyghens thoughtfully cut his food. After a moment:

"The landing was in the winter time," he observed. "It must have been, because the colony survived a while. And at a guess, the last ship-landing was before thaw. The years are eighteen months long here, you know."

"It was in winter that the landing was made," Bordman admitted. "And the last ship-landing was before spring. The idea was to get mines in operation for material, and to have ground cleared and enclosed—in sphex-proof fence before the sphexes came back from the tropics. They winter there, I understand."

"Did you ever see a sphex?" asked Huyghens. Then he said, "No, of course not. But if you took a spitting cobra and crossed it with a wild-cat, painted it tan-and-blue and then gave it hydrophobia and homicidal mania at once, you might have one sphex. But not the race of sphexes. They can climb trees, by the way. A fence wouldn't stop them."

"An electrified fence," said Bordman. "Nothing could climb that!"

"Not one animal," Huyghens told him. "But sphexes are a race. The smell of one dead sphex brings others running with blood in their eyes. Leave a dead sphex alone for six hours and you've got them around by dozens. Two days and there are hundreds. Longer, and you've got thousands of them! They gather to caterwaul over their dead pal and hunt for whoever or whatever killed him."

He returned to his meal. A moment later he said:

"No need to wonder what happened to your colony. During the winter the robots burned out a clearing and put up an electrified fence according to the book. Come spring, the sphexes come back. They're curious, among their other madnesses. A sphex would try to climb the fence just to see what was behind it. He'd be electrocuted. His carcass would bring others, raging because a sphex was dead. Some of them would try to climb the fence, and die. And their corpses would bring others. Presently the fence would break down from the bodies hanging on it, or a bridge of dead beasts' carcasses would be built across it—and from as far downwind as the scent carried there'd be loping, raging, scent-crazed sphexes racing to the spot. They'd pour into the clearing through or over the fence, squalling and screeching for something to kill. I think they'd find it."

Bordman ceased to eat. He looked sick.

"There were pictures of sphexes in the data I read. I suppose that would account for—everything."

He tried to lift his fork. He put it down again. "I can't eat," he said abruptly.

Huyghens made no comment. He finished his own meal, scowling. He rose and put the plates into the top of the cleaner. "Let me see those reports, eh?" he asked dourly. "I'd like to see what sort of a set-up they had, those robots."

Bordman hesitated and then opened his traveling bag. There was a microviewer and records. One entire record was labeled "Specifications for Construction, Colonial Survey," which would contain detailed plans and all requirements of material and workmanship for everything from desks, office, administrative personnel, for use of, to landing-grids, heavy-gravity planets, lift-capacity 100,000 earth-tons. But Huyghens found another. He inserted it and spun the control swiftly here and there, pausing only briefly at index-frames until he came to the section he wanted. He began to study the information with growing impatience.

"Robots, robots, robots!" he snapped. "Why don't they leave them where they belong—in cities to do the dirty work, and on airless planets where nothing unexpected ever happens? Robots don't belong in new colonies. Your colonists depended on them for defense. Dammit, let a man work with robots long enough and he thinks all nature is as limited as they are. This is a plan to set up a controlled environment—on Loren II! Controlled environment—" He swore. "Complacent, idiotic, desk-bound half-wits!"

"Robots are all right," said Bordman. "We couldn't run civilization without them."

"But you can't tame a wilderness with 'em," snapped Huyghens. "You had a dozen men landed, with fifty assembled robots to start with. There were parts for fifteen hundred more, and I'll bet anything I've got the ship-contacts landed more still."

"They did," admitted Bordman.

"I despise 'em," growled Huyghens. "I feel about 'em the way the old Greeks felt about slaves. They're for menial work—the sort of work a man will perform for himself, but that he won't do for another man for pay. Degrading work!"

"Quite aristocratic," said Bordman with a touch of irony. "I take it that robots clean out the bear-quarters downstairs."

"No!" snapped Huyghens. "I do. They're my friends. They fight for me. No robot would do the job right."

He growled, again. The noises of the night went on outside. Organ-tones and hiccoughings and the sound of tack-hammers and slamming doors. Somewhere there was a singularly exact replica of the discordant squeakings of a rusty pump.

"I'm looking," said Huyghens at the microviewer, "for the record of their mining operations. An open-pit operation would not mean a thing. But if they had driven a tunnel, and somebody was there supervising the robots when the colony was wiped out, there's an off-chance he survived a while."

Bordman regarded him with suddenly intent eyes.

"And—"

"Dammit," snapped Bordman, "if so I'll go see! He'd—they'd have no chance at all, otherwise. Not that the chance is good in any case."

Bordman raised his eyebrows.

"I've told you I'll send you to prison if I can," he said. "You've risked the lives of millions of people, maintaining non-quarantined communication with an unlicensed planet. If you did rescue somebody from the ruins of the robot colony—does it occur to you that they'd be witnesses to your unauthorized presence here?"

Huyghens spun the viewer again. He stopped, switched back and forth, and found what he wanted. He muttered in satisfaction: "They did run a tunnel." Aloud he said, "I'll worry about witnesses when I have to."

He pushed aside another cupboard door. Inside it were the odds and ends a man makes use of to repair the things about his house that he never notices until they go wrong. There was an assortment of wires, transistors, bolts, and similar stray items.

"What now?" asked Bordman mildly.

"I'm going to try to find out if there's anybody left alive over there. I'd have checked before if I'd known the colony existed. I can't prove they're all dead, but I may prove that somebody's still alive. It's barely two weeks' journey away from here. Odd that two colonies picked spots so near!"

He picked over the oddments he'd selected:

"Confound it!" Bordman said. "How can you check if somebody's alive some hundreds of miles away?"

Huyghens threw a switch and took down a wall-panel, exposing electronic apparatus and circuits behind. He busied himself with it.

"Ever think about hunting for a castaway?" he asked over his shoulder. "Here's a planet with some tens of millions of square miles on it. You know there's a ship down. You've no idea where. You assume the survivors have power—no civilized man will be without power very long, so long as he can smelt metals—but making a space-beacon calls for high-precision measurements and workmanship. It's not to be improvised. So what will your shipwrecked civilized man do, to guide a rescue-ship to the one or two square miles he occupies among some tens of millions on the planet?"

"What?"

"He's had to go primitive, to begin with," Huyghens explained. "He cooks his meat over a fire, and so on. He has to make a strictly primitive signal. It's all he can do without gauges and micrometers and special tools. But he can fill all the planet's atmosphere with a signal that searchers for him can't miss. You see?"

Bordman thought irritably. He shook his head.

"He'll make," said Huyghens, "a spark transmitter. He'll fix its output at the shortest frequency he can contrive, somewhere in the five-to-fifty-meter wave-band, but it will tune very broad—and it will be a plainly human signal. He'll start it broadcasting. Some of those frequencies will go all around the planet under the ionosphere. Any ship that comes in under the radio roof will pick up his signal, get a fix on it, move and get another fix, and then go straight to where the castaway is waiting placidly in a hand-braided hammock, sipping whatever sort of drink he's improvised out of the local vegetation."

Bordman said grudgingly:

"Now that you mention it, of course . . ."

"My space-phone picks up microwaves," said Huyghens. "I'm shifting a few elements to make it listen for longer stuff. It won't be efficient, but it will catch a distress-signal if one's in the air. I don't expect it, though."

He worked. Bordman sat still a long time, watching him.

Down below, a rhythmic sort of sound arose. It was Sourdough Charley, snoring.

Sitka Pete grunted in his sleep. He was dreaming. In the general room of the station Semper blinked his eyes rapidly and then tucked his head under a gigantic wing and went to sleep. The noises of the Loren II jungle came through the steel-shuttered windows. The nearer moon—which had passed overhead not long before the ringing of the arrival-bell—again came soaring over the eastern horizon. It sped across the sky.

Inside the station, Bordman said angrily:

"See here, Huyghens! You've reason to kill me. Apparently you don't intend to. You've excellent reason to leave that robot colony strictly alone. But you're preparing to help, if there's anybody alive to need it. And yet you're a criminal, and I mean a criminal! There've been some ghastly bacteria exported from planets like Loren II. There've been plenty of lives lost in consequence, and you're risking more. Why the hell do you do it? Why do you do something that could produce monstrous results—to other human beings?"

Huyghens grunted.

"You're assuming there are no sanitary and quarantine precautions taken by my partners. As a matter of fact, there are. They're taken, all right! As for the rest, you wouldn't understand."

"I don't understand," snapped Bordman, "but that's no proof I can't!—Why are you a criminal?"

Huyghens painstakingly used a screwdriver inside the wall-panel. He lifted out a small electronic assembly, and began to fit in a spaghettied new assembly with larger units.

"I'm cutting my amplification here to hell-and-gone," he observed, "but I think it'll do. . . . I'm doing what I'm doing," he added calmly, "because it seems to me it fits what I think I am. Everybody acts according to his own real notion of himself. You're a conscientious citizen, a loyal official, a well-adjusted personality. You act that way. You consider yourself an intelligent rational animal. But you don't act that way! You're reminding me of my need to shoot you or something similar, which a merely rational animal would try to make me forget. You happen, Bordman, to be a man. So am I. But I'm aware of it. Therefore I deliberately do things a merely rational animal wouldn't, because they're my notion of what a man who's more than a rational animal should do."

He tightened one small screw after another.

Bordman said:

"Oh. Religion."

"Self-respect," corrected Huyghens. "I don't like robots. They're too much like rational animals. A robot will do whatever it can that its supervisor requires it to do. A merely rational animal will do whatever circumstances require it to do. I wouldn't like a robot unless it had some idea of what was fitting and would spit in my eye if I tried to make it do something else. The bears downstairs, now . . . They're no robots! They are loyal and honorable beasts, but they'd turn and tear me to bits if I tried to make them do something against their nature. Faro Nell would fight me and all creation together, if we tried to harm Nugget. It would be unintelligent and unreasonable and irrational. She'd lose out and get killed. But I like her that way! And I'll fight you and all creation when you make me try to do something against my nature. I'll be stupid and unreasonable and irrational about it." Then he grinned over his shoulder. "So will you. Only you don't realize it."

He turned back to his task. After a moment he fitted a manual-control knob over a shaft in his haywire assembly. "What did somebody try to make you do?" asked Bordman shrewdly. "What was demanded of you that turned you into a criminal? What are you in revolt against?"

Huyghens threw a switch. He began to turn the knob which controlled his makeshift receiver.

"Why," he said, "when I was young the people around me tried to make me into a conscientious citizen and a loyal employee and a well-adjusted personality. They tried to make me into a highly intelligent rational animal and nothing more. The difference between us, Bordman, is that I found it out. Naturally, I rev—"

He stopped short. Faint, crackling, frying sounds came from the speaker of the space-phone now modified to receive what once were called short waves.

Huyghens listened. He cocked his head intently. He turned the knob very, very slowly. Bordman made an arrested gesture, to call attention to something in the sibilant sound. Huyghens nodded. He turned the knob again, with infinitesimal increments.

Out of the background noise came a patterned mutter. As Huyghens shifted the tuning, it grew louder. It reached a volume where it was unmistakable. It was a sequence of sounds like a discordant buzzing. There were three half-second buzzings with half-second pauses between. A two-second pause. Three full-second buzzings with half-second pauses between. Another two-second pause and three half-second buzzings, again. Then silence for five seconds. Then the pattern repeated.

"The devil!" said Huyghens. "That's a human signal! Mechanically made, too. In fact, it used to be a standard distress call. It was termed an SOS, though I've no idea what that meant. Anyhow, somebody must have read old-fashioned novels some time, to know about it. And so someone is still alive over at your licensed but now smashed-up robot colony. And they're asking for help. I'd say they're likely to need it."

He looked at Bordman.

"The intelligent thing to do is sit back and wait for a ship, either my friends' or yours. A ship can help survivors or castaways much better than we can. It could even find them more easily. But maybe time is important to the poor devils. So I'm going to take the bears and see if I can reach him. You can wait here, if you like. What say?"

Bordman snapped angrily:

"Don't be a fool! Of course I'm coming! What do you take me for? And two of us should have four times the chance of one!"

Huyghens grinned.

"Not quite. You forget Sitka Pete and Sourdough Charley and Faro Nell. There'll be five of us if you come, instead of four. And, of course, Nugget has to come—and he'll be no help—but Semper may make up for him. You won't quadruple our chances, Bordman, but I'll be glad to have you if you want to be stupid and unreasonable and not at all rational, and come with me."

There was a jagged spur of stone looming precipitously over a river-valley. A thousand feet below, a broad stream ran westward to the sea. Twenty miles to the east, a wall of mountains rose sheer against the sky, its peaks seeming to blend to a remarkable evenness of height. Rolling, tumbled ground lay between for as far as the eye could see.

A speck in the sky came swiftly downward. Great pinions spread and flapped, and icy eyes surveyed the rocky space. With more great flappings, Semper the eagle came to ground. He folded his huge wings and turned his head jerkily, his eyes unblinking. A tiny harness held a miniature camera against his chest. He strutted over the bare stone to the highest point and stood there, a lonely and arrogant figure in the vastness.

Crashings and rustlings, and snuffling sounds, and Sitka Pete came lumbering out into the clear space. He wore a harness too, and a pack. The harness was complex, because it had to hold a pack not only in normal travel, but when he stood on his hind legs, and it must not hamper the use of his forepaws in combat.

He went cagily all over the open area. He peered over the edge of the spur's farthest tip, and prowled to the other side and looked down. Once he moved close to Semper and the eagle opened his great curved beak and uttered an indignant noise. Sitka paid no attention.

He relaxed, satisfied. He sat down untidily, his hind legs sprawling. He wore an air approaching benevolence as he surveyed the landscape about and below him.

More snufflings and crashings. Sourdough Charley came into view with Huyghens and Bordman behind him. Sourdough carried a pack, too. Then there was a squealing and Nugget scurried up from the rear, impelled by a whack from his mother. Faro Nell appeared, with the carcass of a stag-like animal lashed to her harness.

"I picked this place from a space-photo," said Huyghens, "to make a directional fix from you. I'll get set up."

He swung his pack from his shoulders to the ground, and extracted an obviously self-constructed device which he set on the ground. It had a whip aerial, which he extended. Then he plugged in a considerable length of flexible wire and unfolded a tiny, improvised directional aerial with an even tinier booster at its base. Bordman slipped his pack from his shoulders and watched. Huyghens put a pair of head-phones over his ears. He looked up and said sharply:

"Watch the bears, Bordman. The wind's blowing up the way we came. Anything that trails us will send its scent on before. The bears will tell us."

He busied himself with the instruments he'd brought. He heard the hissing, frying, background noise which could be anything at all except a human signal. He reached out and swung the small aerial around. Rasping, buzzing tones came in, faintly and then loudly. This receiver, though, had been made for this particular wave-band. It was much more efficient than the modified space-phone had been. It picked up three short buzzes, three long ones, and three short ones again. Three dots, three dashes, and three dots. Over and over again. SOS. SOS. SOS.

Huyghens took a reading and moved the directional aerial a carefully measured distance. He took another reading, shifted it yet again and again, carefully marking and measuring each spot and taking notes of the instrument readings. When he finished, he had checked the direction of the signal not only by loudness but by phase, and had as accurate a fix as could possibly be made with portable apparatus.

Sourdough growled softly. Sitka Pete whiffed the air and arose from his sitting position. Faro Nell whacked Nugget, sending him whimpering to the farthest corner of the flat place. She stood bristling, facing down-hill the way they'd come.

"Damn!" said Huyghens.

He got up and waved his arm at Semper, who had turned his head at the stirrings. Semper squawked and dived off the spur, and was immediately fighting the down-draught beyond it. As Huyghens readied his weapon, the eagle came back overhead. He went magnificently past, a hundred feet high, careening and flapping in the tricky currents. He screamed, abruptly, and screamed again. Huyghens swung a tiny vision-plate from its strap to where he could look into it. He saw, of course, what the tiny camera on Semper's chest could see—reeling, swaying terrain as Semper saw it, though of course without his breadth of field. There were moving objects to be seen through the shifting trees. Their coloring was unmistakable.

"Sphexes," said Huyghens dourly. "Eight of them. Don't look for them to follow our track, Bordman. They run parallel to a trail on either side. That way they attack in breadth and all at once when they catch up. And listen! The bears can handle anything they tangle with—it's our job to pick off the loose ones. And aim for the body! The bullets explode."

He threw off the safety of his weapon. Faro Nell, uttering thunderous growls, went padding to a place between Sitka Pete and Sourdough. Sitka glanced at her and made a whuffing noise, as if derisive of her bloodcurdling sounds. Sourdough grunted. He and Sitka moved farther away from Nell to either side. They would cover a wider front.

There was no other sign of life than the shrillings of the incredibly tiny creatures which on this planet were birds, and Faro Nell's deep-bass, raging growls, and then the click of Bordman's safety going off as he got ready to use the weapon Huyghens had given him.

Semper screamed again, flapping low above the tree-tops, following parti-colored, monstrous shapes beneath.

Eight blue-and-tan fiends came racing out of the underbrush. They had spiny fringes, and horns, and glaring eyes, and they looked as if they had come straight out of hell. On the instant of their appearance they leaped, emitting squalling, spitting squeals that were like the cries of fighting tom-cats ten thousand times magnified. Huyghens' rifle cracked, and its sound was wiped out in the louder detonation of its bullet in sphexian flesh. A tan-and-blue monster tumbled over, shrieking. Faro Nell charged, the very impersonation of white-hot fury. Bordman fired, and his bullet exploded against a tree. Sitka Pete brought his massive forepaws in a clapping, monstrous ear-boxing motion. A sphex died.

Then Bordman fired again. Sourdough Charley whuffed. He fell forward upon a spitting bi-colored fiend, rolled him over, and raked with his hind-claws. The belly-hide of the sphex was tenderer than the rest. The creature rolled away, snapping at its own wounds. Another sphex found itself shaken loose from the tumult about Sitka Pete. It whirled to leap on him from behind, and Huyghens fired. Two plunged upon Faro Nell, and Bordman blasted one and Faro Nell disposed of the other in awesome fury. Then Sitka Pete heaved himself erect—seeming to drip sphexes—and Sourdough waddled over and pulled one off and killed it and went back for 4another. . . . Then both rifles cracked together and there was suddenly nothing left to fight.

The bears prowled from one to another of the corpses. Sitka Pete rumbled and lifted up a limp head. Crash! Then another. He went over the lot, whether or not they showed signs of life. When he had finished, they were wholly still.

Semper came flapping down out of the sky. He had screamed and fluttered overhead as the fight went on. Now he landed with a rush. Huyghens went soothingly from one bear to another, calming them with his voice. It took longest to calm Faro Nell, licking Nugget with impassioned solicitude and growling horribly as she licked.

"Come along, now," said Huyghens, when Sitka showed signs of intending to sit down again. "Heave these carcasses over a cliff. Come along! Sitka! Sourdough! Hup!"

He guided them as the two big males somewhat fastidiously lifted up the nightmarish creatures and carried them to the edge of the spur of stone. They let the beasts go bouncing and sliding down into the valley.

"That," said Huyghens, "is so their little pals will gather round them and caterwaul their woe where there's no trail of ours to give them ideas. If we'd been near a river I'd have dumped them in to float down-stream and gather mourners wherever they stranded. Around the station I incinerate them. If I had to leave them, I'd make tracks away. About fifty miles upwind would be a good idea."

He opened the pack Sourdough carried and extracted giant-sized swabs and some gallons of antiseptic. He tended the three Kodiaks in turn, swabbing not only the cuts and scratches they'd received, but deeply soaking their fur where there could be suspicion of spilled sphex-blood.

"This antiseptic deodorizes, too," he told Bordman. "Or we'd be trailed by any sphex who passed to leeward of us. When we start off, I'll swab the bears' paws for the same reason."

Bordman was very quiet. He'd missed his first shot, but, the last few seconds of the fight he'd fired very deliberately and every bullet hit. Now he said bitterly:

"If you're instructing me so I can carry on should you be killed, I doubt that it's worth while!"

Huyghens felt in his pack and unfolded the enlargements he'd made of the space-photos of this part of the planet. He carefully oriented the map with distant landmarks, and drew a line across the photo.

"The SOS signal comes from somewhere close to the robot colony," he reported. "I think a little to the south of it. Probably from a mine they'd opened up, on the far side of the Sere Plateau. See how I've marked this map? Two fixes, one from the station and one from here. I came away off-course to get a fix here so we'd have two position-lines to the transmitter. The signal could have come from the other side of the planet. But it doesn't."

"The odds would be astronomical against other castaways," protested Bordman.

"No," said Huyghens. "Ships have been coming here. To the robot-colony. One could have crashed. And I have friends, too." He repacked his apparatus and gestured to the bears. He led them beyond the scene of combat and carefully swabbed off their paws, so they could not possibly leave a train of sphex-blood scent behind them. He waved Semper, the eagle, aloft.

"Let's go," he told the Kodiaks. "Yonder! Hup!"

The party headed downhill and into the jungle again. Now it was Sourdough's turn to take the lead, and Sitka Pete prowled more widely behind him. Faro Nell trailed the men, with Nugget. She kept a sharp eye upon the cub. He was a baby, still; he only weighed six hundred pounds. And of course she watched against danger from the rear.

Overhead, Semper fluttered and flew in giant circles and spirals, never going very far away. Huyghens referred constantly to the screen which showed what the air-borne camera saw. The image tilted and circled and banked and swayed. It was by no means the best air-reconnaissance that could be imagined, but it was the best that would work. Presently Huyghens said:

"We swing to the right, here. The going's bad straight ahead, and it looks like a pack of sphexes has killed and is feeding."

Bordman said:

"It's against reason for carnivores to be as thick as you say! There has to be a certain amount of other animal life for every meat-eating beast. Too many of them would eat all the game and starve."

"They're gone all winter," explained Huyghens, "which around here isn't as severe as you might think. And a good many animals seem to breed just after the sphexes go south. Also, the sphexes aren't around all the warm weather. There's a sort of peak, and then for a matter of weeks you won't see one of them, and suddenly the jungle swarms with them again. Then, presently, they head south. Apparently they're migratory in some fashion, but nobody knows." He said dryly: "There haven't been many naturalists around on this planet. The animal life's inimical."

Bordman fretted. He was accustomed to arrival at a partly or completely finished colonial set-up, and to pass upon the completion or non-completion of the installation as designed. Now he was in an intolerably hostile environment, depending upon an illegal colonist for his life, engaged upon a demoralizingly indefinite enterprise—because the mechanical spark-signal could be working long after its constructors were dead—and his ideas about a number of matters were shaken. He was alive, for example, because of three giant Kodiak bears and a bald eagle. He and Huyghens could have been surrounded by ten thousand robots, and they'd have been killed. Sphexes and robots would have ignored each other, and sphexes would have made straight for the men, who'd have had less than four seconds in which to discover for themselves that they were attacked, prepare to defend themselves, and kill the eight sphexes.

He found Nugget, the cub, ambling uneasily in his wake. The cub flattened his ears miserably when Bordman glanced at him. It occurred to the man that Nugget was receiving a lot of disciplinary thumpings from Faro Nell. He was knocked about psychologically. His lack of information and unfitness for independent survival in this environment was being hammered into him.

"Hi, Nugget," said Bordman ruefully. "I feel just about the way you do!"

Nugget brightened visibly. He frisked. He tended to gambol. He looked hopefully up into Bordman's face.

The man reached out and patted Nugget's head. It was the first time in all his life that he'd ever petted an animal.

He heard a snuffling sound behind him. Skin crawled at the back of his neck. He whirled.

Faro Nell regarded him—eighteen hundred pounds of she-bear only ten feet away and looking into his eyes. For one panicky instant Bordman went cold all over. Then he realized that Faro Nell's eyes were not burning. She was not snarling, nor did she emit those blood-curdling sounds which the bare prospect of danger to Nugget had produced up on the rocky spur. She looked at him blandly. In fact, after a moment she swung off on some independent investigation of a matter that had aroused her curiosity.

The traveling-party went on, Nugget frisking beside Bordman and tending to bump into him out of pure cub-clumsiness. Now and again he looked adoringly at Bordman, in the instant and overwhelming affection of the very young.

Bordman trudged on. Presently he glanced behind again. Faro Nell was now ranging more widely. She was well satisfied to have Nugget in the immediate care of a man. From time to time he got on her nerves.

A little while later, Bordman called ahead.

"Huyghens! Look here! I've been appointed nursemaid to Nugget!"

Huyghens looked back.

"Oh, slap him a few times and he'll go back to his mother."

"The devil I will!" said Bordman querulously. "I like it!"

The traveling-party went on.

When night fell, they camped. There could be no fire, of course, because all the minute night-things about would come to dance in the glow. But there could not be darkness, equally, because night-walkers hunted in the dark. So Huyghens set out barrier-lamps which made a wall of twilight about their halting-place, and the stag-like creature Faro Nell had carried became their evening meal. Then they slept—at least the men did—and the bears dozed and snorted and waked and dozed again. Semper sat immobile with his head under his wing on a tree-limb. Presently there was a glorious cool hush and all the world glowed in morning-light diffused through the jungle by a newly risen sun. Then they arose and pushed on.

This day they stopped stock-still for two hours while sphexes puzzled over the trail the bears had left. Huyghens discoursed on the need of an anti-scent, to be used on the boots of men and the paws of bears, which would make the following of their trails unpopular with sphexes. Bordman seized upon the idea and suggested that a sphex-repellant odor might be worked out, which would make a human revolting to a sphex. If that were done, humans could go freely about, unmolested.

"Like stink-bugs," said Huyghens, sardonically. "A very intelligent idea! Very rational! You can feel proud!"

And suddenly Bordman was not proud of the idea at all. They camped again. On the third night they were at the base of that remarkable formation, the Sere Plateau, which from a distance looked like a mountain range but was actually a desert table-land. It was not reasonable for a desert to be raised high, while lowlands had rain, but on the fourth morning they found out why. They saw, far, far away, a truly monstrous mountain-mass at the end of the long expanse of the plateau. It was like the prow of a ship. It lay, so Huyghens observed, directly in line with the prevailing winds, and divided them as a ship's prow divides the waters. The moisture-bearing air-currents flowed beside the plateau, not over it, and its interior was desert in the unscreened sunshine of the high altitudes.

It took them a full day to get half-way up the slope. And here, twice, as they climbed, Semper flew screaming over aggregations of sphexes to one side of them or the other. These were much larger groups than Huyghens had ever seen before, fifty to a hundred monstrosities together, where a dozen was a large hunting-pack elsewhere. He looked in the screen which showed him what Semper saw, four to five miles away. The sphexes padded uphill toward the Sere Plateau in a long line. Fifty—sixty—seventy tan-and-azure beasts out of hell.

"I'd hate to have that bunch jump us," he said candidly to Bordman. "I don't think we'd stand a chance."

"Here's where a robot tank would be useful," Bordman observed.

"Anything armored," conceded Huyghens. "One man in an armored station like mine would be safe. But if he killed a sphex he'd be besieged. He'd have to stay holed up, breathing the smell of dead sphex, until the odor'd gone away. And he mustn't kill any others or he'd be besieged until winter came."

Bordman did not suggest the advantages of robots in other directions. At that moment, for example, they were working their way up a slope which averaged fifty degrees. The bears climbed without effort despite their burdens. For the men it was infinite toil. Semper, the eagle, manifested impatience with bears and men alike, who crawled so slowly up an incline over which he soared.

He went ahead up the mountainside and teetered in the air currents at the plateau's edge. Huyghens looked in the vision-plate by which he reported.

"How the devil," panted Bordman, panting—they had stopped for a breather, and the bears waited patiently for them—"how do you train bears like these? I can understand Semper."

"I don't train them," said Huyghens, staring into the plate. "They're mutations. In heredity the sex-linkage of physical characteristics is standard stuff. There's also been some sound work done on the gene-linkage of psychological factors. There was need, on my home planet, for an animal who could fight like a fiend, live off the land, carry a pack and get along with men at least as well as dogs do. In the old days they'd have tried to breed the desired physical properties in an animal who already had the personality they wanted. Something like a giant dog, say. But back home they went at it the other way about. They picked the wanted physical characteristics and bred for the personality, the psychology. The job got done over a century ago. The Kodiak bear named Kodius Champion was the first real success. He had everything that was wanted. These bears are his descendants."

"They look normal," commented Bordman.

"They are!" said Huyghens warmly. "Just as normal as an honest dog. They're not trained, like Semper. They train themselves." He looked back into the plate in his hands, which showed the ground six or seven thousand feet higher. "Semper, now, is a trained bird without too much brain. He's educated—a glorified hawk. But the bears want to get along with men. They're emotionally dependent on us. Like dogs. Semper's a servant, but they're companions and friends. He's trained, but they're loyal. He's conditioned. They love us. He'd abandon me if he ever realized he could; he thinks he can only eat what men feed him. But the bears wouldn't want to. They like us. I admit I like them. Maybe because they like me."

Bordman said deliberately:

"Aren't you a trifle loose-tongued, Huyghens? You've told me something that will locate and convict the people who set you up here. It shouldn't be hard to find where bears were bred for psychological mutations, and where a bear named Kodius Champion left descendants. I can find out where you came from now, Huyghens!"

Huyghens looked up from the plate with its tiny swaying television image.

"No harm done," he said amiably. "I'm a criminal there, too. It's officially on record that I kidnapped these bears and escaped with them. Which, on my home planet, is about as heinous a crime as a man can commit. It's worse than horse-theft back on Earth in the old days. The kin and cousins of my bears are highly thought of. I'm quite a criminal, back home." Bordman stared.

"Did you steal them?" he demanded.

"Confidentially," said Huyghens, "no. But prove it!" Then he said: "Take a look in this plate. See what Semper can see up at the plateau's edge."

Bordman squinted aloft, where the eagle flew in great sweeps and dashes. Somehow, by the experience of the past few days, Bordman knew that Semper was screaming fiercely as he flew. He made a dart toward the plateau's border.

Bordman looked at the transmitted picture. It was only four inches by six, but it was perfectly without grain and accurate in color. It moved and turned as the camera-bearing eagle swooped and circled. For an instant the screen showed the steeply sloping mountainside, and off at one edge the party of men and bears could be seen as dots. Then it swept away and showed the top of the plateau.

There were sphexes. A pack of two hundred trotted toward the desert interior. They moved at leisure, in the open. The viewing camera reeled, and there were more. As Bordman watched and as the bird flew higher, he could see still other sphexes moving up over the edge of the plateau from a small erosion-defile here and another one there. The Sere Plateau was alive with the hellish creatures. It was inconceivable that there should be game enough for them to live on. They were visible as herds of cattle would be visible on grazing planets.

It was simply impossible.

"Migrating," observed Huyghens. "I said they did. They're headed somewhere. Do you know, I doubt that it would be healthy for us to try to cross the Plateau through such a swarm of sphexes!"

Bordman swore, in abrupt change of mood.

"But the signal's still coming through. Somebody's alive over at the robot colony. Must we wait till the migration's over?"

"We don't know," Huyghens pointed out, "that they'll stay alive. They may need help badly. We have to get to them. But at the same time—"

He glanced at Sourdough Charley and Sitka Pete, clinging patiently to the mountainside while the men rested and talked. Sitka had managed to find a place to sit down, one massive paw anchoring him in place.

Huyghens waved his arm, pointing in a new direction. "Let's go!" he called briskly. "Let's go! Yonder! Hup!"

They followed the slopes of the Sere Plateau, neither ascending to its level top—where spheres congregated—nor descending into the foothills where spheres assembled. They moved along hillsides and mountain-flanks which sloped anywhere from thirty to sixty degrees, and they did not cover much territory. They practically forgot what it was to walk on level ground.

At the end of the sixth day, they camped on the top of a massive boulder which projected from a mountainous stony wall. There was barely room on the boulder for all the party. Faro Nell fussily insisted that Nugget should be in the safest part, which meant near the mountain-flank. She would have crowded the men outward, but Nugget whimpered for Bordman. Wherefore, when Bordman moved to comfort him, Faro Neil drew back and snorted at Sitka and Sourdough and they made room for her near the edge.

It was a hungry camp. They had come upon tiny rills upon occasion, flowing down the mountainside. Here the bears had drunk deeply and the men had filled canteens. But this was the third night on the mountainside, and there had been no game at all. Huyghens made no move to bring out food for Bordman or himself. Bordman made no comment. He was beginning to participate in the relationship between bears and men, which was not the slavery of the bears but something more. It was two-way. He felt it.

"You'd think," he said, "that since the sphexes don't seem to hunt on their way uphill, there should be some game. They ignore everything as they file up."

This was true enough. The normal fighting formation of sphexes was line abreast, which automatically surrounded anything which offered to flee and outflanked anything which offered fight. But here they ascended the mountain in long files, one after the other, apparently following long-established trails. The wind blew along the slopes and carried scent sidewise. But the sphexes were not diverted from their chosen paths. The long processions of hideous blue-and-tawny creatures—it was hard to think of them as natural beasts, male and female and laying eggs like reptiles on other planets—the long processions simply climbed.

"There've been other thousands of beasts before them," said Huyghens. "They must have been crowding this way for days or even weeks. We've seen tens of thousands in Semper's camera. They must be uncountable, altogether. The first-comers ate all the game there was, and the last-comers have something else on whatever they use for minds."

Bordman protested:

"But so many carnivores in one place is impossible! I know they are here, but they can't be!"

"They're cold-blooded," Huyghens pointed out. "They don't burn food to sustain body-temperature. After all, lots of creatures go for long periods without eating. Even bears hibernate. But this isn't hibernation—or estivation, either."

He was setting up the radiation-wave receiver in the darkness. There was no point in attempting a fix here. The transmitter was on the other side of the sphex-crowded Sere Plateau. The men and bears would commit suicide by crossing here.

Even so, Huyghens turned on the receiver. There came the whispering, scratchy sound of background-noise, and then the signal. Three dots, three dashes, three dots. Huyghens turned it off. Bordman said:

"Shouldn't we have answered that signal before we left the station? To encourage them?"

"I doubt they have a receiver," said Huyghens. "They won't expect an answer for months, anyhow. They'd hardly listen all the time, and if they're living in a mine-tunnel and trying to sneak out for food to stretch their supplies, they'll be too busy to try to make complicated recorders or relays."

Bordman was silent for a moment or two.

"We've got to get food for the bears," he said presently. "Nugget's weaned, and he's hungry."

"We will," Huyghens promised. "I may be wrong, but it seems to me that the number of sphexes climbing the mountain is less than yesterday and the day before. We may have just about crossed the path of their migration. They're thinning out. When we're past their trail, we'll have to look out for nightwalkers and the like again. But I think they wiped out all animal life on their migration-route."

He was not quite right. He was waked in darkness by the sound of slappings and the grunting of bears. Feather-light puffs of breeze beat upon his face. He struck his belt-lamp sharply and the world was hidden by a whitish film which snatched itself away. Something flapped. Then he saw the stars and the emptiness on the edge of which they camped. Then big white things flapped toward him.

Sitka Pete whuffed mightily and swatted. Faro Nell grunted and swung. She caught something in her claws.

"Watch this!" said Huyghens.

More things strangely-shaped and pallid like human skin reeled and flapped crazily toward him.

A huge hairy paw reached up into the light-beam and snatched a flying thing out of it. Another great paw. The three great Kodiaks were on their hind legs, swatting at creatures which flittered insanely, unable to resist the fascination of the glaring lamp. Because of their wild gyrations it was impossible to see them in detail, but they were those unpleasant night-creatures which looked like plucked flying monkeys but were actually something quite different.

The bears did not snarl or snap. They swatted, with a remarkable air of business-like competence and purpose. Small mounds of broken things built up about their feet.

Suddenly there were no more. Huyghens snapped off the light. The bears crunched and fed busily in the darkness.

"Those things are carnivores and blood-suckers, Bordman," said Huyghens calmly. "They drain their victims of blood like vampire-bats—they've some trick of not waking them—and when they're dead the whole tribe eats. But bears have thick fur, and they wake when they're touched. And they're omnivorous. They'll eat anything but sphexes, and like it. You might say that those night-creatures came to lunch. They are it, for the bears, who are living off the country as usual."

Bordman uttered a sudden exclamation. He made a tiny light, and blood flowed down his hand. Huyghens passed over his pocket kit of antiseptic and bandages. Bordman stanched the bleeding and bound up his hand. Then he realized that Nugget chewed on something. When he turned the light, Nugget swallowed convulsively. It appeared that he had caught and devoured the creature which had drawn blood from Bordman. But he'd lost none to speak of, at that.

In the morning they started along the sloping scarp of the plateau once more. After marching silently for awhile, Bordman said:

"Robots wouldn't have handled those vampire-things, Huyghens."

"Oh, they could be built to watch for them," said Huyghens, tolerantly. "But you'd have to swat for yourself. I prefer the bears."

He led the way on. Twice Huyghens halted to examine the ground about the mountains' bases through binoculars. He looked encouraged as they went on. The monstrous peak which was like the bow of a ship at the end of the Sere Plateau was visibly nearer. Toward midday, indeed, it loomed high above the horizon, no more than fifteen miles away. And at midday Huyghens called a final halt.

"No more congregations of sphexes down below," he said cheerfully, "and we haven't seen a climbing line of them in miles." The crossing of a sphex-trail had meant simply waiting until one party had passed; and then crossing before another came in view. "I've a hunch we've left their migration route behind. Let's see what Semper tells us!"

He waved the eagle aloft. Like all creatures other than men, the bird normally functioned only for the satisfaction of his appetite, and then tended to loaf or sleep. He had ridden the last few miles perched on Sitka Pete's pack. Now he soared upward and Huyghens watched in the small vision-plate.

Semper went soaring. The image on the plate swayed and turned, and in minutes was above the plateau's edge. Here there were some patches of brush and the ground rolled a little. But as Semper towered higher still, the inner desert appeared. Nearby, it was clear of beasts. Only once, when the eagle banked sharply and the camera looked along the long dimension of the plateau, did Huyghens see any sign of the blue-and-tan beasts. There he saw what looked like masses amounting to herds. Incredible, of course; carnivores do not gather in herds.

"We go straight up," said Huyghens in satisfaction. "We cross the Plateau here, and we can edge downwind a bit, even. I think we'll find something interesting on our way to your robot colony."

He waved to the bears to go ahead uphill.

They reached the top hours later, barely before sunset. And they saw game. Not much, but game at the grassy, brushy border of the desert. Huyghens brought down a shaggy ruminant which surely would not live on a desert. When night fell there was an abrupt chill in the air. It was much colder than night temperatures on the slopes. The air was thin. Bordman thought and presently guessed at the cause. In the lee of the prow-mountain the air was calm. There were no clouds. The ground radiated its heat to empty space. It could be bitterly cold in the night-time, here.

"And hot by day," Huyghens agreed when he mentioned it. "The sunshine's terrifically hot where the air is thin, but on most mountains there's wind. By day, here, the ground will tend to heat up like the surface of a planet without atmosphere. It may be a hundred and forty or fifty degrees on the sand at midday. But it should be cold at night."

It was. Before midnight Huyghens built a fire. There could be no danger of night-walkers where the temperature dropped to freezing.

In the morning the men were stiff with cold, but the bears snorted and moved about briskly. They seemed to revel in the morning chill. Sitka and Sourdough Charley, in fact, became festive and engaged in a mock fight, whacking each other with blows that were only feigned, but would have crushed the skull of any man. Nugget sneezed with excitement as he watched them. Faro Nell regarded them with female disapproval.

They started on. Semper seemed sluggish. After a single brief flight he descended and rode on Sitka's pack, as on the previous day. He perched there, surveying the landscape as it changed from semi-arid to pure desert in their progress. He would not fly. Soaring birds do not like to fly when there are no winds to make currents of which they can take advantage.

Once Huyghens stopped and pointed out to Bordman exactly where they were on the enlarged photograph taken from space, and the exact spot from which the distress-signal seemed to come.

"You're doing it in case something happens to you," said Bordman. "I admit it's sense, but—what could I do to help those survivors even if I got to them, without you?"

"What you've learned about sphexes would help," said Huyghens. "The bears would help. And we left a note back at my station. Whoever grounds at the landing field back there—and the beacon's working—will find instructions to come to the place we're trying to reach."

They started walking again. The narrow patch of non-desert border of the Sere Plateau was behind them, now, and they marched across powdery desert sand.

"See here," said Bordman. "I want to know something. You tell me you're listed as a bear-thief on your home planet. You tell me it's a lie, to protect your friends from prosecution by the Colonial Survey. You're on your own, risking your life every minute of every day. You took a risk in not shooting me. Now you're risking more in going to help men who'd have to be witnesses that you were a criminal. What are you doing it for?" Huyghens grinned.

"Because I don't like robots. I don't like the fact that they're subduing men, making men subordinate to them."

"Go on," insisted Bordman. "I don't see why disliking robots should make you a criminal! Nor men subordinating themselves to robots, either."

"But they are," said Huyghens mildly. "I'm a crank, of course. But—I live like a man on this planet. I go where I please and do what I please. My helpers are my friends. If the robot colony had been a success, would the humans in it have lived like men? Hardly. They'd have to live the way robots let them! They'd have to stay inside a fence the robots built. They'd have to eat foods that robots could raise, and no others. Why, a man couldn't move his bed near a window, because if he did the house-tending robots couldn't work! Robots would serve them—the way the robots determined—but all they'd get out of it would be jobs servicing the robots!"

Bordman shook his head.

"As long as men want robot service, they have to take the service that robots can give. If you don't want those services—"

"I want to decide what I want," said Huyghens, again mildly, "instead of being limited to choose what I'm offered. In my home planet we half-way tamed it with dogs and guns. Then we developed the bears, and we finished the job with them. Now there's population-pressure and the room for bears and dogs—and men!—is dwindling. More and more people are being deprived of the power of decision, and being allowed only the power of choice among the things robots allow. The more we depend on robots, the more limited those choices become. We don't want our children to limit themselves to wanting what robots can provide! We don't want them shriveling to where they abandon everything robots can't give, or won't. We want them to be men and women. Not damned automatons who live by pushing robot-controls so they can live to push robot-controls. If that's not subordination to robots—"

"It's an emotional argument," protested Bordman. "Not everybody feels that way."

"But I feel that way," said Huyghens. "And so do a lot of others. This is a damned big galaxy and it's apt to contain some surprises. The one sure thing about a robot and a man who depends on them is that they can't handle the unexpected. There's going to come a time when we need men who can. So on my home planet, some of us asked for Loren II, to colonize. It was refused—too dangerous. But men can colonize anywhere if they're men. So I came here to study the planet. Especially the sphexes. Eventually, we expected to ask for a license again, with proof that we could handle even those beasts. I'm already doing it in a mild way. But the Survey licensed a robot colony—and where is it?"

Bordman made a sour face.

"You took the wrong way to go about it, Huyghens. It was illegal. It is. It was the pioneer spirit, which is admirable enough, but wrongly directed. After all, it was pioneers who left Earth for the stars. But—"

Sourdough raised up on his hind-legs and sniffed the air. Huyghens swung his rifle around to be handy. Bordman slipped off the safety-catch of his own. Nothing happened.

"In a way," said Bordman, "you're talking about liberty and freedom, which most people think is politics. You say it can be more. In principle, I'll concede it. But the way you put it, it sounds like a freak religion."

"It's self-respect," corrected Huyghens. "You may be—"

Faro Nell growled. She bumped Nugget with her nose, to drive him closer to Bordman. She snorted at him, and trotted swiftly to where Sitka and Sourdough faced toward the broader, sphex-filled expanse of the Sere Plateau. She took up her position between them.

Huyghens gazed sharply beyond them and then all about. "This could be bad!" he said softly. "But luckily there's no wind. Here's a sort of hill. Come along, Bordman!"

He ran ahead, Bordman following and Nugget plumping heavily with him. They reached the raised place, actually a mere hillock no more than five or six feet above the surrounding sand, with a distorted cactus-like growth protruding from the ground. Huyghens stared again. He used his binoculars.

"One sphex," he said curtly. "Just one! And it's out of all reason for a sphex to be alone. But it's not rational for them to gather in hundreds of thousands, either!" He whetted his finger and held it up. "No wind at all."

He used the binoculars again.

"It doesn't know we're here," he added. "It's moving away. Not another one in sight. . . ." He hesitated, biting his lip. "Look here, Bordman! I'd like to kill that one lone sphex and find out something. There's a fifty per cent chance I could find out something really important. But—I might have to run. If I'm right . . ." Then he said grimly, "It'll have to be done quickly. I'm going to ride Faro Nell, for speed. I doubt Sitka or Sourdough will stay behind. But Nugget can't run fast enough. Will you stay here with him?"

Bordman drew in his breath. Then he said calmly: "You know what you're doing, I hope."

"Keep your eyes open. If you see anything, even at a distance, shoot and we'll be back, fast! Don't wait until something's close enough to hit. Shoot the instant you see anything, if you do!"

Bordman nodded. He found it peculiarly difficult to speak again. Huyghens went over to the embattled bears and climbed up on Faro Nell's back, holding fast by her shaggy fur.

"Let's go!" he snapped. "That way! Hup!"

The three Kodiaks plunged away at a dead run, Huyghens lurching and swaying on Faro Nell's back. The sudden rush dislodged Semper from his perch. He flapped wildly and got aloft. Then he followed effortfully, flying low.

It happened very quickly. A Kodiak bear can travel as fast as a race-horse on occasion. These three plunged arrow-straight for a spot perhaps half a mile distant, where a blue-and-tawny shape whirled to face them. There was the crash of Huyghens' weapon from where he rode on Faro Nell's back; the explosion of the weapon and the bullet was one sound. The monster leaped and died.

Huyghens jumped down from Faro Nell. He became feverishly busy at something on the ground. Semper banked and whirled and landed. He watched, with his head on one side.

Bordman stared. Huyghens was doing something to the dead sphex. The two male bears prowled about, while Faro Nell regarded Huyghens with intense curiosity. Back at the hillock, Nugget whimpered a little, and Bordman patted him. Nugget whimpered more loudly. In the distance, Huyghens straightened up and mounted Faro Nell's back. Sitka looked back toward Bordman. He reared upward. He made a noise, apparently, because Sourdough ambled to his side. The two great beasts began to trot back. Semper flapped wildly and—lacking wind—lurched crazily in the air. He landed on Huyghens' shoulder and clung there with his talons.

Then Nugget howled hysterically and tried to swarm up Bordman, as a cub tries to swarm up the nearest tree in time of danger. Bordman collapsed, and the cub upon him—and there was a flash of stinking scaly hide, while the air was filled with the snarling, spitting squeals of a sphex in full leap. The beast had over-jumped, aiming at Bordman and the cub while both were upright and arriving when they had fallen. It went tumbling.

Bordman heard nothing but the fiendish squalling, but in the distance Sitka and Sourdough were coming at rocket-ship speed. Faro Nell let out a roar that fairly split the air. And then there was a furry streaking toward her, bawling, while Bordman rolled to his feet and snatched up his gun. He raged through pure instinct. The sphex crouched to pursue the cub and Bordman swung his weapon as a club. He was literally too close to shoot—and perhaps the sphex had only seen the fleeing bear-cub. But he swung furiously.

And the sphex whirled. Bordman was toppled from his feet. An eight-hundred-pound monstrosity straight out of hell—half wildcat and half spitting cobra with hydrophobia and homicidal mania added—such a monstrosity is not to be withstood when in whirling its body strikes one in the chest.

That was when Sitka arrived, bellowing. He stood on his hind legs, emitting roars like thunder, challenging the sphex to battle. He waddled forward. Huyghens approached, but he could not shoot with Bordman in the sphere of an explosive bullet's destructiveness. Faro Nell raged and snarled, torn between the urge to be sure that Nugget was unharmed, and the frenzied fury of a mother whose offspring has been endangered.

Mounted on Faro Nell, with Semper clinging idiotically to his shoulder, Huyghens watched helplessly as the sphex spat and squalled at Sitka, having only to reach out one claw to let out Bordman's life.

They got away from there, though Sitka seemed to want to lift the limp carcass of his victim in his teeth and dash it repeatedly to the ground. He seemed doubly raging because a man—with whom all Kodius Champion's descendants had an emotional relationship—had been mishandled. But Bordman was not grievously hurt. He bounced and swore as the bears raced for the horizon. Huyghens had flung him up on Sourdough's pack and snapped for him to hold on. He shouted:

"Damn it, Huyghens! This isn't right! Sitka got some deep scratches! That horror's claws may be poisonous!"

But Huyghens snapped "Hup! Hup!" to the bears, and they continued their race against time. They went on for a good two miles, when Nugget wailed despairingly of his exhaustion and Faro Nell halted firmly to nuzzle him.

"This may be good enough," said Huyghens. "Considering that there's no wind and the big mass of beasts is down the plateau and there were only those two around here. Maybe they're too busy to hold a wake, even. Anyhow—"

He slid to the ground and extracted the antiseptic and swabs. "Sitka first," snapped Bordman. "I'm all right!"

Huyghens swabbed the big bear's wounds. They were trivial, because Sitka Pete was an experienced sphex-fighter. Then Bordman grudgingly let the curiously-smelling stuff—it reeked of ozone—be applied to the slashes on his chest. He held his breath as it stung. Then he said:

"It was my fault, Huyghens. I watched you instead of the landscape. I couldn't imagine what you were doing."

"I was doing a quick dissection," Huyghens told him. "By luck, that first sphex was a female, as I hoped. And she was about to lay her eggs. Ugh! And now I know why the sphexes migrate, and where, and how it is that they don't need game up here."

He slapped a quick bandage on Bordman then led the way eastward, still putting distance between the dead sphexes and his party.

"I'd dissected them before," said Huyghens. "Not enough's been known about them. Some things needed to be found out if men were ever to be able to live here."

"With bears?" asked Bordman ironically.

"Oh, yes," said Huyghens. "But the point is that sphexes come to the desert here to breed, to mate and lay their eggs for the sun to hatch. It's a particular place. Seals return to a special place to mate—and the males, at least, don't eat for weeks on end. Salmon return to their native streams to spawn. They don't eat, and they die afterward. And eels—I'm using Earth examples, Bordman—travel some thousands of miles to the Sargasso to mate and die. Unfortunately, sphexes don't appear to die, but it's clear that they have an ancestral breeding-place and that they come to the Sere Plateau to deposit their eggs!"

Bordman plodded onward. He was angry; angry with himself because he hadn't taken elementary precautions; because he'd felt too safe, as a man in a robot-served civilization forms the habit of doing; because he hadn't used his brain when Nugget whimpered, with even a bear-cub's awareness that danger was near.

"And now," Huyghens added, "I need some equipment that the robot colony has. With it, I think we can make a start toward turning this into a planet that man can live like men on." Bordman blinked.

"What's that?"

"Equipment," said Huyghens impatiently. "It'll be at the robot colony. Robots were useless because they wouldn't pay attention to sphexes. They'd still be. But take out the robot controls and the machines will do. They shouldn't be ruined by a few months' exposure to weather."

Bordman marched on and on. Presently he said:

"I never thought you'd want anything that came from that colony, Huyghens!"

"Why not?" demanded Huyghens impatiently. "When men make machines do what they want, that's all right. Even robots, when they're where they belong. But men will have to handle flame-casters in the job I want them for. There have to be some, because there was a hundred-mile clearing to be burned off for the colony. And earth-sterilizers, intended to kill the seeds of any plants that robots couldn't handle. We'll come back up here, Bordman, and at the least we'll destroy the spawn of these infernal beasts! If we can't do more than that, just doing that every year will wipe out the race in time. There are probably other hordes than this, with other breeding-places. But we'll find them too. We'll make this planet into a place where men from my world can come and still be men!"

Bordman said sardonically:

"It was sphexes that beat the robots. Are you sure you aren't planning to make this world safe for robots?"

Huyghens laughed.

"You've only seen one night-walker," he said. "And how about those things on the mountain-slope, which would have drained you of blood? Would you care to wander about this planet with only a robot body-guard, Bordman? Hardly! Men can't live on this planet with only robots to help them. You'll see!"

They found the colony after only ten days' more travel and after many sphexes and more than a few stag-like creatures and shaggy ruminants had fallen to their weapons and the bears. And they found survivors.

There were three of them, hard-bitten and bearded and deeply embittered. When the electrified fence went down, two of them were away at a mine tunnel, installing a new control panel for the robots who worked in it. The third was in charge of the mining operation. They were alarmed by the stopping of communication with the colony and went back in a tank-truck to find out what had happened, and only the fact that they were unarmed saved them. They found sphexes prowling and caterwauling about the fallen colony, in numbers they still did not wholly believe. The sphexes smelled men inside the armored vehicle, but couldn't break in. In turn, the men couldn't kill them, or they'd have been trailed to the mine and besieged there for as long as they could kill an occasional monster.

The survivors stopped all mining, of course, and tried to use remote-controlled robots for revenge and to get supplies for them. Their mining-robots were not designed for either task. And they had no weapons. They improvised miniature throwers of burning rocket-fuel, and they sent occasional prowling sphexes away screaming with scorched hides. But this was useful only because it did not kill the beasts. And it cost fuel. In the end they barricaded themselves and used the fuel only to keep a spark-signal going against the day when another ship came to seek the colony. They stayed in the mine as in a prison, on short rations, without real hope. For diversion they could only contemplate the mining-robots they could not spare fuel to run and which could not do anything but mine.

When Huyghens and Bordman reached them, they wept. They hated robots and all things robotic only a little less than they hated sphexes. But Huyghens explained, and, armed with weapons from the packs of the bears, they marched to the dead colony with the male Kodiaks as point and advance-guard, and with Faro Nell bringing up the rear. They killed sixteen sphexes on the way. In the now overgrown clearing there were four more. In the shelters of the colony they found only foulness and the fragments of what had been men. But there was some food—not much, because the sphexes clawed at anything that smelled of men, and had ruined the plastic packets of radiation-sterilized food. But there were some supplies in metal containers which were not destroyed.

And there was fuel, which men could use when they got to the control-panels of the equipment. There were robots everywhere, bright and shining and ready for operation, but immobile, with plants growing up around and over them.

They ignored those robots, and instead fueled tracked flame-casters—after adapting them to human rather than robot operation—and the giant soil-sterilizer which had been built to destroy vegetation that robots could not be made to weed out or cultivate. Then they headed back for the Sere Plateau.

As time passed Nugget became a badly spoiled bear-cub, because the freed men approved passionately of anything that would even grow up to kill sphexes. They petted him to excess when they camped.

Finally they reached the plateau by a sphex-trail to the top and sphexes came squalling and spitting to destroy them. While Bordman and Huyghens fired steadily, the great machines swept up with their special weapons. The earth-sterilizer, it developed, was deadly against animal life as well as seeds, when its diathermic beam was raised and aimed.

Presently the bears were not needed, because the scorched corpses of sphexes drew live ones from all parts of the plateau even in the absence of noticeable breezes. The official business of the sphexes was presumably finished, but they came to caterwaul and seek vengeance—which they did not find. After a while the survivors of the robot colony drove the machines in great circles around the huge heap of slaughtered fiends, destroying new arrivals as they came. It was such a killing as men had never before made on any planet, and there would be very few left of the sphex-horde which had bred in this particular patch of desert.

Nor would more grow up, because the soil-sterilizer would go over the dug-up sand where the sphex-spawn lay hidden for the sun to hatch. And the sun would never hatch them.

Huyghens and Bordman, by that time, were camped on the edge of the plateau with the Kodiaks. Somehow it seemed more befitting for the men of the robot colony to conduct the slaughter. After all, it was those men whose companions had been killed.

There came an evening when Huyghens cuffed Nugget away from where he sniffed too urgently at a stag-steak cooking on the campfire. Nugget ambled dolefully behind the protecting form of Bordman and sniveled.

"Huyghens," said Bordman, "we've got to come to a settlement of our affairs. You're an illegal colonist, and it's my duty to arrest you."

Huyghens regarded him with interest.

"Will you offer me lenience if I tell on my confederates?" he asked, "or may I plead that I can't be forced to testify against myself?"

Bordman said:

"It's irritating! I've been an honest man all my life, but—I don't believe in robots as I did, except in their place. And their place isn't here! Not as the robot colony was planned, anyhow. The sphexes are nearly wiped out, but they won't be extinct and robots can't handle them. Bears and men will have to live here or else the people who do will have to spend their lives behind sphex-proof fences, accepting only what robots can give them. And there's much too much on this planet for people to miss it! To live in a robot-managed environment on a planet like Loren II wouldn't—it wouldn't be self-respecting!"

"You wouldn't be getting religious, would you?" asked Huyghens drily. "That was your term for self-respect before."

"You don't let me finish!" protested Bordman. "It's my job to pass on the work that's done on a planet before any but the first-landed colonists may come there to live. And of course to see that specifications are followed. Now, the robot colony I was sent to survey was practically destroyed. As designed, it wouldn't work. It couldn't survive."

Huyghens grunted. Night was falling. He turned the meat over the fire.

"In emergencies," said Bordman, "colonists have the right to call on any passing ship for aid. Naturally! So my report will be that the colony as designed was impractical, and that it was overwhelmed and destroyed except for three survivors who holed up and signaled for help. They did, you know!"

"Go on," grunted Huyghens.

"So," said Bordman, "it just happened—just happened, mind you—that a ship with you and the bears and the eagle on board picked up the distress-call. So you landed to help the colonists. That's the story. Therefore it isn't illegal for you to be here. It was only illegal for you to be here when you were needed. But we'll pretend you weren't."

Huyghens glanced over his shoulder in the deepening night. He said:

"I wouldn't believe that if I told it myself. Do you think the Survey will?"

"They're not fools," said Bordman tartly. "Of course they won't! But when my report says that because of this unlikely series of events it is practical to colonize the planet, whereas before it wasn't, and when my report proves that a robot colony alone is stark nonsense, but that with bears and men from your world added, so many thousand colonists can be received per year . . . And when that much is true, anyhow . . .

Huyghens seemed to shake a little as a dark silhouette against the flames.

"My reports carry weight," insisted Bordman. "The deal will be offered, anyhow! The robot colony organizers will have to agree or they'll have to fold up. And your people can hold them up for nearly what terms they choose."

Huyghens' shaking became understandable. It was laughter. "You're a lousy liar, Bordman," he said. "Isn't it unintelligent and unreasonable to throw away a lifetime of honesty just to get me out of a jam? You're not acting like a rational animal, Bordman. But I thought you wouldn't, when it came to the point."

Bordman squirmed.

"That's the only solution I can think of," he said. "But it'll work."

"I accept it," said Huyghens, grinning. "With thanks. If only because it means another few generations of men can live like men on a planet that is going to take a lot of taming. And—if you want to know—because it keeps Sourdough and Sitka and Nell and Nugget from being killed because I brought them here illegally."

Something pressed hard against Bordman: Nugget, the cub, pushed urgently against him in his desire to get closer to the fragrantly cooking meat. He edged forward. Bordman toppled from where he squatted on the ground. He sprawled. Nugget sniffed luxuriously.

"Slap him," said Huyghens. "He'll move back."

"I won't!" said Bordman indignantly from where he lay. "I won't do it. He's my friend!"

It was ironic that, after all, Bordman found that he couldn't afford to retire. His pay, of course, had been used to educate his children and maintain his home. And Lani III was an expensive world to live on. It was now occupied by a thriving, bustling population with keen business instincts, and the vapor-curtains about it were commonplaces, now, and few people remembered a time when they hadn't existed, when it was a world below habitability for anybody. So Bordman wasn't a hero. As a matter of history he had done such and such. As a matter of fact he was simply a citizen who could be interviewed for visicasts on holidays, but hadn't much that was new to say.

But he lived on Lani III for three years, and he was restless. His children were grown and married, now, and they hadn't known him too well, anyhow. He'd been away so much! He didn't fit into the world whose green fields and oceans and rivers he was responsible for. But it was infinitely good to be with Riki again. There was so much that each remembered, to be shared with the other, that they had plenty to talk about.

Three years after his official retirement, he was asked to take on another Survey job for which there was no other qualified man. He talked to his wife. On retirement pay, life was not easy. In retirement, it wasn't satisfactory. And Riki was free too, now. Her children were safely on their own. Bordman would always need her. She advised him for both their sakes. And he went back to Survey duty with the stipulation that he should have quarters and facilities for his wife as well as himself on all assignments.
