"Oh, no," said Wisby. "I keep them in their place around my post. But times are changing. It can't be helped."

"There was a time when they were slaves," said Riordan. "Now those old women on Earth want to give 'em the vote." He snorted.

"Well, times are changing," repeated Wisby mildly. "When the first humans landed on Mars a hundred years ago, Earth had just gone through the Hemispheric Wars. The worst wars man had ever known. They damned near wrecked the old ideas of liberty and equality. People were suspicious and tough—they'd had to be, to survive. They weren't able to—to empathize the Martians, or whatever you call it. Not able to think of them as 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.

They 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?"
