<passage>:
Then he rushed, the flame-torch making a roaring sound. effective against such creatures as these. Torches were contact weapons Moran cut apart the yard-long monstrosity with a slash of flame. The thing presumably died, but it continued to writhe senselessly. He turned to see other horrors crawling toward him. Then he knew he was being marooned on a planet of endless terrors. Moran, naturally, did not mean to help in the carrying out of the plans disgusting legs of the thing still kicked spasmodically—quite separate—on the whitish ground-stuff. Moran had disliked such creatures in miniature form on other worlds. Enlarged like this. complicated. It had turned out, in fact, to be the ecological system of Earth, and unless all parts of the complex were present, the total was subtly or glaringly wrong. So mankind distastefully ferried pests as necessary to get rid of Moran. In their predicament he might have come well as useful creatures to its new worlds as they were made ready for settlement. Mosquitos throve on the inhabited globes of the Rim Stars. Roaches twitched nervous antennae on the settled planets of the humanity spread through the galaxy with an attendant train of insects and annoyances. If they left their pests behind, the total system of checks and balances which make life practical would get lopsided. It would not maintain itself. The vagaries that could result were admirably illustrated in and on the landscape outside the prominences erupting about its edges. Now it lay astern, and Moran . Something had been left out of the seeding of this planet. The element—which might be a bacterium or a virus or almost anything at all—the element that kept creatures at the size called "normal" was either missing or inoperable here. The results were not desirable. nowhere else. There was an ice-cap in view. The rest was—clouds. The ice-cap, by its existence and circular shape, proved that the planet Moran observed these things from the control-room of the "It doesn't look too bad, Moran!" Moran disagreed, but he did not answer. He cocked an ear instead. He passage leading away. He called. But Moran observed with grudging investigation. Moran, at least, would be picked out as a fugitive from or other, so the people could find that spot again. It was supposed to be a long time ago, though." government of their native world, and they'd gotten away to make it seem the revolt had collapsed. They'd go back later when they weren't expected, and start it up again. Moran considered the story probable. Only people accustomed to desperate actions would have remained so calm when Moran had used desperate measures against them. though, and Moran grimaced. they had revolted, and what sort of set-back to the revolt had sent the five off in what they considered a strategic retreat but their government would think defeat. Moran's own situation was perfectly which was the reason for what Moran had done. But the dead man had been very important, and the fact that Moran had forced him to fight and killed him in fair combat made no difference. Moran had needed to get designed to prevent such escapes. He'd made a pretty good try, at that. One of the controls on was out of overdrive they efficiently gave him his choice of surrendering or else. He surrendered, stipulating that he wouldn't be very much like a small boy trailing a stick against a picket fence, only much louder. Something hooted, maintaining the noise for an impossibly alive. And something shrieked in lunatic fashion and something else still moaned from time to time with the volume of a steam-whistle.... "What's that stuff there, the ground?" he demanded. "We burned it away "That," said Moran as if brightly, "that's what I'm to make a garden in. Moran said bitingly fore part was crushed in. The other landing-fins could be traced. "It's a ship," said Moran curtly. "It crash-landed and its crew set up a "Sure," said Moran, "but a man can gripe, can't he?" that I take a torch. We may have to burn through that loathesome stuff Moran silently went to the space-suit rack and began to get into a "Ah, yes!" said Moran. "It's very likely that the ship hit hard enough world. Moran, though, would not be permitted a weapon. He picked up a planet. They looked dubiously at the scorched, indefinite substance which had been ground before the Nadine landed. Moran moved scornfully The hole exposed a cheesy mass of soft matter which seemed riddled with small holes. Something black came squirming frantically out of one of the openings. It was eight or ten inches long. It had a head, a thorax, and an abdomen. It had wing-cases. It had six legs. It toppled down to the Moran kicked again. More holes. More openings. More small tunnels in the cheese-like, curd-like stuff. More black things squirming to view in obvious panic. They popped out everywhere. It was suddenly apparent " They're—bugs! " she said incredulously. " They're beetles! They're twenty times the size of the beetles we humans have been carrying around the galaxy, but that's what they are! " Moran grunted. Distastefully, he saw his predicament made worse. He knew food. So an elaborate adaptation job had to be done on every planet before native and terrestrial living things settled down together. It wasn't impossible that the scuttling things were truly beetles, grown large and monstrous under the conditions of a new planet. And the ground.... "This ground stuff," said Moran distastefully, "is yeast or some sort of toadstool growth. This is a seedling world. It didn't have any life on it, so somebody dumped germs and spores and bugs to make it ready for plants and animals eventually. But nobody's come back to finish up the job." Something moved. It came out from behind a very minor spire of whitish stuff that looked like a dirty sheet stretched over a tall stone. The thing that appeared was very peculiar indeed. It was a—worm. But it was a foot thick and ten feet long, and it had a group of stumpy legs at its fore end—where there were eyes hidden behind bristling hair-like growths—and another set of feet at its tail end. It progressed sedately by reaching forward with its fore-part, securing a foothold, and then arching its middle portion like a cat arching its back, to bring its hind part forward. Then it reached forward again. It was of a dark olive color from one end to the other. Its manner of walking was insane but somehow sedate. Moran heard muffled noises in his helmet-phone as the others tried to " Moran said with savage precision "We're looking at an inch-worm, grown up like the beetles only more so. It's not an inch-worm any longer. It's a yard-worm." Then he said harshly to the men with him They reached the mound which was the ship. Moran unlimbered his torch. Without orders, he turned on the torch. A four-foot flame of pure leaped up. He used the flame like a gigantic scalpel, cutting a square a creatures in their labyrinths of tunnels began to panic. Off to the right the blanket-like surface ripped and they poured out. They scuttled crazily here and there. Some took to wing. By instinct the other Moran slashed and slashed angrily with the big flame, cutting a way to the metal hull that had fallen here before his grandfather was born. Sometimes the flame cut across things that writhed, and he was sickened. " Look out! It's coming! Kill it! Kill it—. "
