They weren't human. They were something more—and something less—they were, be restless to end her fool's errand here, two hundred light years from the waiting hordes on Earth. Straining metal plates twanged and echoed through her hallways. a big, rawboned man, barely forty but ten years of responsibility had pressed down his shoulders and put age-feigning hollows under his reddened eyes. The starlanes between Earth and her potential colonies were rough on the men who traveled them now. He shuffled toward the control room, grumbling at the heavy gravity. Lieutenant Jane Corey looked up, nodding a blonde head at him as he "About a dozen blobs held something like a convention a little ways clouds." The blobs were a peculiarity of this planet about which nobody knew anything. They looked like overgrown fireballs, but seemed to have an almost sentient curiosity about anything moving on the ground. "And in the murk. I've kept a signal going to guide them back." in the schools, so promising kids were being shipped out for training as cadets on their twelfth birthday. The two he'd drawn, Kaufman and seemed dangerous, and the local animals were apparently all herbivorous and harmless. They were ugly enough, looking like insects in spite of their internal skeletons, with anywhere from four to twelve legs each on their segmented bodies. None acted like dangerous beasts. But glowed yellow-green. Motions around them suggested a herd of feeding animals. Details were impossible to see through the haze. Even the There were three of the blobs dancing about over the grazing animals the kids!" The blobs had left the herd. Now the three were streaking at fantastic speed to a spot near the ship, to hover excitedly above something that They must have seen whatever it was just as the call reached them. Young Kaufman grabbed at Pinelli, and they swung around together. Then the mists cleared. Under the dancing blobs, a horde of things was heading for the cadets. Shaggy heads, brute bodies vaguely man-like! One seemed to be almost eight feet tall, leading the others directly toward the spacesuited cadets. Some of the horde were carrying spears or sticks. There was a momentary halt, and then the leader lifted one arm, as if motioning the confusion. But someone was taking over now—one of the crew women. The irritating and vile smelling, but it could be breathed. He leaped to surrounded by the menacing horde. Seen from here, the things looked horrible in a travesty of manhood. miles an hour now, but the horde began to increase the distance, in spite of the load of the two struggling boys! The creatures dived "Follow the blobs," Gwayne yelled. He realized now he'd been a fool to Then it cleared to show the mob of creatures doubling back on their own There was no time to stop. The jeep plowed through them. Gwayne had a glimpse of five-foot bodies tumbling out of the way. Monstrously coarse faces were half hidden by thick hair. A spear crunched against the The creatures vanished as Barker fought to turn to follow them. The to help. They'd have to get to the group with the cadets in a hurry or the horde would all vanish in the uneven ground, hidden by the fog. He threw up an instinctive hand. There was a tingling as the creature against the windshield, just as he made out the form of the eight-foot leader. The thing was standing directly ahead of him, a cadet on each shoulder. for the figure. It dropped the boys with a surprised grunt. The arms were thin and grotesque below the massively distorted shoulders, but amazingly strong. Gwayne felt them wrench at him as his hands locked on the thick throat. A stench of alien flesh was in his makes no sense. We've scoured this planet by infra-red, and there was "Troglodytes, maybe," Gwayne guessed. "Anyhow, send for me when you get busy being little heroes. Gwayne sentenced them to quarters as soon as he could, knowing their stories would only get wilder and less informative with retelling. If they could get any story from the captured creature, they might save these creatures that a space ship's metal finders could be fooled by a began filling worlds with colonists, carried in deep sleep to conserve would be spawning grounds for mankind in spite of the efforts. Each was Primitives could be overcome, maybe. It would be ruthless and unfair to But how could primitives do what these must have done? "Beautiful primitive work," he muttered. He went to the port and glanced out. About sixty of the things were They were perhaps a thousand yards away, waiting patiently. For what? For the return of their leader—or for something that would give the "Haarroo, Cabbaan!" the thing said. taut with strain. The creature nodded slowly and drew something from the thick hair on well. Says they've had to change the language around to make the sounds fit, and he's forgotten how to use what normal English he can. But it gets easier as you listen. It's Hennessy, all right. I'm certain." Gwayne had his own ideas on that. It was easy for an alien to seize English, maybe. But Hennessy had been his friend. "How many barmaids in the Cheshire Cat? How many pups did your oldest kid's dog have? How many were brown?" The lips contorted into something vaguely like a smile, and the curiously shaped fingers that could handle no human-designed equipment spread out. Three. Seven. Zero. The answers were right. long time telling. When it was finished, Gwayne and Barker sat for long minutes in by what I know. But it happened. I've looked at a few tissues under the microscope. The changes are there. It's hard to believe about their kids. Adults in eight years, but they stay shorter. It can't be a hereditary change—the things that affect the body don't change the germ plasm. But in this case, what changed Hennessy is real, so maybe down to touch the monstrous man, then leaped up again. The crowd of monsters began moving forward toward their leader. A few were almost as tall as Hennessy, but most were not more than five feet high. The kids of the exploring party.... He'd have to tell the men and women of the crew later, after he'd had however much they might hate it at first. But there was no putting off giving the gist of it to Jane. "It was the blobs," he summarized it. "They seem to be amused by men. They don't require anything from us, but they like us around. Hennessy doesn't know why. They can change our cells, adapt us. Before men came, all life here had twelve legs. Now they're changing that, as we've seen. "And they don't have to be close to do it. We've all been outside the know." Nobody would know. Their children—odd children who matured in eight years—would be primitive savages in three generations. The Earth puzzlement in her face. "Why?" And then, before he could answer, her own intelligence gave her the Here, though, the blobs had adapted men to the alien world instead of some of the attitudes of civilized man would remain to make the next rise to culture a better one. "We're needed here," he told her, his voice pleading for the understanding he couldn't yet fully give himself. "These people need as rich a set of bloodlines as possible to give the new race strength. The fifty men and women on this ship will be needed to start them with accept the idea—or even let us come back. We have to stay here." She smiled then and moved toward him, groping for his strength. "Be fruitful," she whispered. "Be fruitful and spawn and replenish an earth." "No," he told her. "Replenish the stars." numbering. Some day, the whole universe would be a spawning ground for the children of men!
