Out Saturn-way even the tiniest outpost assumes importance far beyond its size. The slab of rock was no more than five miles across, perhaps even less. Here in its approximate center, were two buildings, both of almost identical construction, semi-spherical and metal.

But I know will fit." of the Ring knew just exactly what kind of spacecraft the other had. "That's right," said Gus, "and I'm fixing to go over into Thirty-seven with the gang from Thirty-seven." Gus stared in disbelief. "There's something in what she says," defended Moe. "You ring-rats been ripping up space for a long time now. Time you growed up and settled down. You're aiming on going over right now and pulverizing Bud. It won't do you any good." "Space polo," said Gus. "And that ain't all," said Moe, warming to the subject. "Those crates "You're prejudiced," Gus told Moe. "You just don't like space polo, The man flipped back his helmet, revealing a head thatched by white hair and dominated by a pair of outsize spectacles. "My opinion, sir," said Oliver Meek, "seldom amounts to much." "All we want to know," Gus told him, "is what you think of space polo." "Space polo," declared Meek, "is a noble game. It requires expert "Sure," said Gus. "Old Gus Hamilton. Grow the finest dog-gone radiation moss you ever clapped your eyes on." "Then you're the gentleman who has bugs," said Meek. "Now, look here," warned Gus, "you watch what you say or I'll hang one on you." "He means your rock bugs," Moe explained, hastily. "Yes," said Meek, "I'm interested in them. I'd like to see them." "See them," said Gus. "Mister, you can have them if you want them. Drove me out of house and home, they did. They're dippy over metal. Any kind of metal, but alloys especially. Eat the stuff.

You can walk right among them if you want to, long as you're walking on the stilts." The bugs had dug a new set of holes, much after the manner of a Chinese knew now he was no expert.

Men loneliness, dared death when crunching orbits intersected or, when mockery of space before them. Meek shrugged his shoulders, almost upsetting himself. The bugs had started the game and Meek craned forward cautiously, watching eagerly, stylus poised above the notebook. Crawling clumsily, the tiny insect-like creatures moved about, solemnly popping in and out of holes. If there were opposing sides ... and if it were a game, there'd have side. Suddenly there was confusion on the board. For a moment a half-dozen of the bugs raced madly about, as if seeking the proper hole to occupy. Then, as suddenly, all movement had ceased. And in another moment, they was falling directly over the board on which the bugs were arrayed. He pawed and kicked at space, but still floated down, course unchanged. He struck and bounced, struck and bounced again. before him. It was covered with the bugs. "Gus will give me hell for this," he told himself.

Gus inched the lid of the wooden box open. Meek rose and popped the bug inside. "That makes twenty-eight of them," said Meek. "I told you," Gus accused him, "that we hadn't got them all.
