“It’s like the story of a battle,” the boy replied musingly. “Here’s one small beast that eats grass, and another small beast that eats flesh. The carnivore will eat the herbivore if he can catch him. So the whole family of herbivore has to learn to run faster than his enemy. The enemy, accordingly, gets bigger. Or, perhaps, the herbivore gets arms, and the carnivore has to be more powerful, with sharper teeth and claws. And so it goes on, each developing something against the other, until beast of prey or victim becomes so big or so clumsy that he can’t develop any further. Then, since neither can ever go backward over the path of progress, either all the grass-eaters get eaten up and their race becomes extinct, or they learn how to escape from the carnivore and that race dies off because it can’t catch its dinner.”

Antoine nodded his head.

“It is a story of battle,” he said, “a battle against other animals or a battle against cold. Look how many beasts have entered into the battle with Man, Perry, and how most of them have lost! The little wild cow was wise, and, as Kipling tells, became Man’s Third Friend, and so, to-day, the cow has developed and increased, so that there is hardly a country on the globe where the cow does not live in peace and comfort. But the Buffalo of the Plains gave fight to Man, he put down his horns and shaggy mane and bellowed his defiance. And so, Perry, beneath an inch or so of prairie soil lie the bones of hundreds of thousands of buffalo, and a few half-tame herds alone remain of the vast hordes that roamed the plains and gave food and a livelihood to the Indians.”
