anything but intelligent animals. And Martians made such useful slaves—they need so little food or heat or oxygen, they can even live fifteen minutes or so without breathing at all. And the wild Martians made fine sport—intelligent game, that could get away as often as not, or even manage to kill the hunter." "I know," said Riordan. "That's why I want to hunt one. It's no fun if the game doesn't have a chance." "It's different now," went on Wisby. "Earth has been at peace for a long time. The liberals have gotten the upper hand. Naturally, one of their first reforms was to end Martian slavery." Riordan swore. The forced repatriation of Martians working on his spaceships had cost him plenty. "I haven't time for your philosophizing," he said. "If you can arrange for me to get a Martian, I'll make it worth your while." "How much worth it?" asked Wisby. hey haggled for a while before settling on a figure. Riordan had brought guns and a small rocketboat, but Wisby would have to supply radioactive material, a "hawk," and a rockhound. Then he had to be paid for the risk of legal action, though that was small. The final price came high. "Now, where do I get my Martian?" inquired Riordan. He gestured at the two in the street. "Catch one of them and release him in the desert?" It was Wisby's turn to be contemptuous. "One of them? Hah! Town loungers! A city dweller from Earth would give you a better fight." The Martians didn't look impressive. They stood only some four feet high on skinny, claw-footed legs, and the arms, ending in bony four-fingered hands, were stringy. The chests were broad and deep, but the waists were ridiculously narrow. They were viviparous, warm-blooded, and suckled their young, but gray feathers covered their hides. The round, hook-beaked heads, with huge amber eyes and tufted feather ears, showed the origin of the name "owlie." They wore only pouched belts and carried sheath knives; even the liberals of Earth weren't ready to allow the natives modern tools and weapons. There were too many old grudges. "The Martians always were good fighters," said Riordan. "They wiped out quite a few Earth settlements in the old days." "The wild ones," agreed Wisby. "But not these. They're just stupid laborers, as dependent on our civilization as we are. You want a real old timer, and I know where one's to be found."
