"I don't want to sound overskeptical," he said at last, "but all this seems rather speculative. Such references could well be to nothing more than mythical creations—similar to our own heroes of folklore."

"That occurred to me, too," Hunt conceded. "But thinking about it, I'm not so sure. The Lunarians were the last word in pragmatism—they had no time for romanticism, religion, matters of the spirit, or anything like that. In the situation they were in, the only people who could help them were themselves, and they knew it. They couldn't afford the luxury and the delusion of inventing gods, heroes, and Father Christmases to work their problems out for them." He shook his head. "I don't believe the Lunarians made up any legends about these Giants. That would have been too much out of character."

"Very well," Danchekker agreed, returning to his meal. "The Lunarians were aware of the prior existence of the Ganymeans. I suspect, however, that you had more than that in mind when you called."

"You're right," Hunt said. "While I was going through the texts, I pulled together some other bits and pieces that are more in your line."

"Go on."

"Well, supposing for the moment that the Ganymeans did ship a whole zoo out to Minerva, the Lunarian biologists later on would have had a hell of a problem making any sense out of what they found all around them, wouldn't they? I mean, with two different groups of animals loose about the place, totally unrelated—and bearing in mind that they couldn't have known what we know about terrestrial species . . ."

"Worse than that, even," Danchekker supplied. "They would have been able to trace the native Minervan species all the way back to their origins; the imported types, however, would extend back through only twenty-five million years or so. Before that, there would have been no record of any ancestors from which they could have descended."

"That's precisely one of the things I wanted to ask you," Hunt said. He leaned forward and rested his elbows on the table. "Suppose you were a Lunarian biologist and knew only the facts he would have known. What sort of picture would it have added up to?"

Danchekker stopped chewing and thought for a long time, his eyes staring far beyond where Hunt was sitting. At length he shook his head slowly.

"That is a very difficult question to answer. In that situation one might, I suppose, speculate that the Ganymeans had introduced alien species. But on the other hand, that is what a biologist from Earth would think; he would be conditioned to expect a continuous fossil record stretching back over hundreds of millions of years. A Lunarian, without any such conditioning, might not regard the absence of a complete record as in any way abnormal. If that was part of the accepted way of things in the world in which he had grown up . . ."
