"Nine ... ten years. Say, what's it to you?"
"And why, Ryd?"
"Why...? Look, mister, I was a helio operator." He hunched his narrow shoulders and spread his hands in an habitual gesture of defeat. "Damn good one, too—I was a foreman ten years ago. But I don't have the physique for Mars—I might just have made it then, but I thought the plant was going to open again and—"
And that was it. The almost airless Martian sky, with its burning actinic rays, is so favorable for the use of the helio-dynamic engine. And after the middle of the eighth century, robot labor gave Mars its full economic independence—and domination. For power is—power; and there is the Restriction Act to keep men on Earth even if more than two in ten could live healthily on the outer world.
"Ten years ago," Mury nodded as if satisfied. "That must have been the Power Company of North America—the main plant by Dynamopolis itself, that shut down in December, 809. They were the last to close down outside the military bases in the Kun Lun."
Ryd was pacing beside him now. He felt a queer upsurge of confidence in this strange man; for too long he had met no sympathy and all too few men who talked his language. He burst out: "They wouldn't take me, damn them! Said my record wasn't good enough for them. That is, I didn't have a drag with any of the Poligerents."
"I know all about your record," said Mury softly.
Ryd's suspicions came back abruptly, and he reverted to his old kicked-dog manner. "How do you know? And what's it to you?"
All at once, Mury came to a stop, and swung around to face him squarely, hard eyes compelling. They were on an overpass, not far from where the vast, almost wholly deserted offices of the Triplanet Freighting Company sprawled over a square mile of city. A half-smile twisted Mury's thin lips.
