welfare worker tried to stop the Ring Rats' feud comparison. Out Saturn-way even the tiniest outpost assumes importance realized, shelter was the thing. Architecture merely for architecture's Saturn Inn The rest of the rock was landing field, pure and simple. Blasters had leveled off the humps and irregularities so spaceships could sit down. puzzler. Meek wrinkled his brow and blinked his eyes, trying to figure out what a welfare ship would be doing in this remote corner of the Solar System. or twice he stumbled, hoping fervently he wouldn't get the feet of his cumbersome spacesuit all tangled up. The gravity was slight, next to non-existent, and one who wasn't used to it had to take things easy and Saturn were the spangled glistening rainbows of the other rings. space, he knew, was not in the least poetic. It was hard and savage and as he thought about that, he hitched up his gun belt and struck out with a firmer tread that almost upset him. After that, he tried to think of nothing except keeping his two feet under him. Reaching the repair shop's entrance lock, he braced himself solidly to be-whiskered roamer of the outer orbits. Meek's hair was white and Even the bulky spacesuit failed to hide his stooped shoulders and slight frame. The mechanic said nothing. "I ran into a swarm of pebbles," Meek confessed. "Not much more than dust, really, but the screen couldn't stop it all." He fumbled his hands self-consciously. "Awkward of me," he said. "It happens to the best of them," the mechanic consoled. "Saturn sweeps alone? No one with you?" that ever took to space." until just a while ago, I never had left Earth. Bookkeeper for Lunar belong ain't the right word because they were on the rock before Gus sure run him ragged. First year they almost drove him loopy trying to figure out what kind of game they were playing." "Game?" asked Meek, wondering if he was being hoaxed. figured out, they'd change the rules and throw him off again." "That doesn't make sense," protested Meek. "Stranger," declared the mechanic, solemnly, "there ain't nothing Gus thinks maybe the rock don't even belong to the Solar system. Thinks maybe it's a hunk of stone from some other solar system. Figures maybe it crossed space somehow and was captured by Saturn, sucked into the find him?" "Go over to the Inn and wait around," advised the mechanic. "He'll come in sooner or later. Drops around regular, except when his worth it, either. Just ring-rats, that's all they are." "But those terrible feuds," she protested. "Fighting just because they live in different parts of the Ring. It's natural they might feel some rivalry, but all this killing! Surely they don't enjoy getting killed." "Sure they enjoy it," declared Moe. "Not being killed, maybe ... although they're willing to take a chance on that. Not many of them get killed, in fact. Just a few that get sort of careless. But even if didn't have their feud they'd plain die of boredom. They just got to "But they could fight with something besides guns," said the welfare lady, a-smirk with righteousness. "That's why I'm here. To try to get them to turn their natural feelings of rivalry into less deadly and disturbing channels. Direct their energies into other activities." demanded. "Got your message, I did, and here I am. But it better be important." him, keeping out of reach. "Have some trouble?" he asked, trying to be casual. "Revenuer?" "Nope. From the welfare outfit.

"You shut your trap," snapped Gus. "She wants us to play games, don't once you got him in the open." Miss Perkins gasped. "Why, I'm sure they wouldn't!" kind of metal, but alloys especially. Eat the stuff. They'll tromp you to death heading for a spaceship. Got so I had to move over to another rock to live. Tried to fight it out with them, but they whipped me pure and simple. Moved out and let them have the place after they started to "Can't get near them, then," he said. "Sure you can," said Gus. "Why not?" "Well, a spacesuit's metal and...." Seem to be scared of it, sort of. You can walk right among them if you want to, long as you're walking on the stilts." Meek gulped. He could imagine what stilt walking would be like in a place where gravity was no more than the faintest whisper. stone that jutted from the surface. practically no gravity, a man had to be an expert to handle them. Meek out the game. Apparently, in each case, the game had been finished. Which, Meek knew, should have meant that some solution had been reached, some point won, some advantage gained. The whole Saturnian system was wacky. The rings, for example. Debris of a moon smashed up by Saturn's pull? Sweepings of space? No one knew. Saturn itself, for that matter. A planet that kept Man at bay with deadly radiations. But radiations that, while they kept Man at a One of the few forms of plant life found in the cold of space, the moss was nurtured by those mysterious radiations. Planted elsewhere, on kindlier worlds, it wilted and refused to grow. The radiations had could not be analyzed. Under the artificial radiation, the moss still And because Earth needed the moss to cure a dozen maladies and because it would grow nowhere else but here on the Inner Ring, men squatted on the crazy swirl of spacial boulders that made up the ring. Men like Hamilton, living on rocks that bucked and heaved along their orbits like chips riding the crest of a raging flood. Men who endured loneliness, dared death when crunching orbits intersected or, when rickety spacecraft flared, who went mad with nothing to do, with the mockery of space before them. Crawling clumsily, the tiny insect-like creatures moved about, solemnly recognize, might determine the number and order of moves allowed each side. going back several plays beyond the point of confusion. Just as one would do when one made a mistake working a mathematical problem ... going back to the point of error and going on again from there. on the rock below. He pawed and kicked at space, but still floated down, course unchanged. scurrying within it. the same again. If we don't watch out, we'll find ourselves being polite to one another." "That would be awful," agreed Meek. "I told you," Gus accused him, "that we hadn't got them all. You better take another good look at your suit. The danged things burrow right into solid metal and pull the hole in after them, seems like. Sneakiest cusses in the whole dang system. Just like chiggers back on Earth." "Chiggers," Meek told him, "burrow into a person to lay eggs." "Maybe these things do, too," Gus contended. in on one of the regular newscasts from Titan City out on Saturn's played at Greater New York on Earth.
