Captain Gwayne cursed and rolled over, reaching for his boots. He was Gwayne swore softly to himself. Earth couldn't turn out enough starmen Pinelli, seemed to be totally devoid of any sense of caution. Of course there was no obvious need for caution here. The blobs hadn't 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 something had happened to the exploration party fifteen years deep gorge where they'd found Hennessy's carefully buried ship was now, as they often seemed to do. Gwayne stared at them for a minute, But there was no time. Earth had ordered him to detour here, after leaving his load of deep-sleep stored colonists on Official World 71, to check on any sign already. If there was no sign in another day or so of what had happened to the men who'd deserted their ship and its equipment, he'd have to He would have left before, if a recent landslip hadn't exposed enough of the buried ship for his metal locators to spot from the air by Gwayne grabbed the microphone, yelling into the radio toward the cadets. "Get the jeeps out!" Gwayne yelled at Jane. He yanked the door of Gwayne dashed for it as the exit port slid back. There was no sign of the cadets at first. Then Gwayne spotted them "Follow the blobs," Gwayne yelled. He realized now he'd been a fool to the radio would have let him keep in contact with the kids. But it was too late to go back. had to slow as the fog thickened lower down. Then it cleared to show the mob of creatures doubling back on their own trail to confuse the pursuers. There was no time to stop. The jeep plowed through them. Gwayne had a windshield from behind, and Gwayne caught it before it could foul 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. A blob dropped down, almost touching Gwayne. He threw up an instinctive hand. There was a tingling as the creature Abruptly, Barker's foot ground at the brake. Gwayne jolted forward leaped back. But Gwayne was out of the jeep before it stopped, diving shoulders, but amazingly strong. Gwayne felt them wrench at him as his sound, and it collapsed. Gwayne eased back slowly, but it made no "I hope so," Gwayne told him. "I want that thing to live—and you're and why that ship was buried against detection. This thing may be the sickly. Smoke and this air made a foul combination. "Bob, it still makes no sense. We've scoured this planet by infra-red, and there was no sign of native villages or culture. We should have found some." "Troglodytes, maybe," Gwayne guessed. "Anyhow, send for me when you get our time here already." The reports from the cadets were satisfactory enough. They'd been picked up and carried, but no harm had been done them. Now they were busy being little heroes. Gwayne sentenced them to quarters as soon as he could, knowing their stories would only get wilder and less was almost certainly spoorless by now. The only possible answer seemed to be that the exploring expedition and Hennessy's rescue group had been overcome by the aliens. primitives have gotten to the men inside Hennessy's ship? Why was its fuel dumped? Only men would have known how to do that. And who told cunningly, and only the accidental slippage had undone their work. remotely habitable, or mankind was probably doomed to extinction. The race had blundered safely through its discovery of atomic weapons into a peace that had lasted two hundred years. It had managed to prevent an interplanetary war with the Venus colonists. It had found It wouldn't be much of an explosion, as such things go—but it would render the whole Solar System uninhabitable for millenia. To survive, man had to colonize. And there were no worlds perfect for him, as Earth had been. The explorers went out in desperation to find what they could the terraforming teams did what they could. And then the big starships began filling worlds with colonists, carried in deep sleep to conserve space. Almost eighty worlds. The nearest a four month journey from Earth and In another ten years, the sun would explode, leaving man only on the footholds he was trying to dig among other solar systems. Maybe some would be spawning grounds for mankind in spite of the efforts. Each was precious as a haven for the race. ship to them? Gwayne grabbed the phone and called Barker. "How's the captive coming?" "Physically fine. You can see him. But—" Gwayne dropped the phone and headed for the little sick bay. He swore at Doc for not calling him at once, and then at himself for not sound that lifted the hair along the nape of Gwayne's neck. Barker some kind of a salute as he saw Gwayne enter, and his eyes burned up "Captain Gwayne, may I present your former friend, Captain Hennessy?" Gwayne had his own ideas on that. It was easy for an alien to seize curiously shaped fingers that could handle no human-designed equipment spread out. Three. Seven. Zero. The answers were right. By the time the session was over, Gwayne had begun to understand the When it was finished, Gwayne and Barker sat for long minutes in silence. Finally Gwayne drew a shuddering breath and stood up. "Is it 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 Gwayne led the former Hennessy to the exit. The waiting blobs dropped Back in the control room, Gwayne found the emergency release levers, He'd have to tell the men and women of the crew later, after he'd had giving the gist of it to Jane. "It was the blobs," he summarized it. "They seem to be amused by men. 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 hull. It doesn't show yet—but we're changed. In another month, Earth food would kill us. We've got to stay here. We'll bury the ships deeper this time, and Earth won't find us. They can't risk trying a colony where three ships vanish, so we'll just disappear. And they'll never know." Nobody would know. Their children—odd children who matured in eight years—would be primitive savages in three generations. The Earth don't know you as well as I do, Bob. I guess we can fix it so they'll believe it all. And it's too late now. But we haven't really been changed yet, have we?" "No," he admitted. Damn his voice! He'd never been good at lying. "No. They have to touch us. I've been touched, but the rest could go back." seed, but no world other than Earth could ever be trusted to preserve that seed for generation after generation. Some worlds already were becoming uncertain. 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 a decent chance. We can't go to Earth, where nobody would believe or accept the idea—or even let us come back. We have to stay here." numbering. Some day, the whole universe would be a spawning ground for the
