"I think I will have Wind blow up a storm, and set the jungle on fire with Lightning. Then, when the fire drives them up the mountain side, some of them will surely wander into the valleys." So the Wind blew up a great storm, and the Lightning flashed and set the jungle on fire, and all the beasts ran before the flames, afraid. Some went in one direction and some in another, but a few of the ape-like animals ran into the hills, and here they found a wide, peaceful valley, with a stream running through it, and plenty of food about for them to eat, so they took refuge there. It was not so warm in the mountain country as it had been in the jungle below, because the higher up in the air we go, the cooler it gets, and we often see snow on the tops of high mountains, even in the middle of summer. And where it is cooler, the trees do not grow so thick and tall and close together as they do in the hot jungle. So the trees and bushes in the valley which the ape-like creatures had found were smaller, and easier to climb than the ones they had been used to, and on many of them the fruit and nuts hung so close to the ground that they could easily be picked without climbing at all. There were no savage animals in the valley, either, for the fierce flesh-eating beasts preferred to stay down in the jungle, where there was always plenty for them to eat. The ape creatures had an easy time of it in their new home. When they saw that no enemies came to eat them up, and that there was plenty of food all about, fruit, and nuts, and sweet-tasting roots that grew underground, they began to get out of the habit of spending all their time in the trees. But they still ran about on all fours, like the other animals. When Mother Nature came along she was very much pleased. "They are beginning to change already," she said. "See how much larger and stronger they are. But I think I might as well take away their tails." "Why?" said the Sun. "It seems to me their tails are very useful things. Some of the monkeys down in the jungle are beginning to use them to help themselves in climbing about in the trees." "That is all very well for monkeys," smiled Mother Nature. "They need them, for they are going to be monkeys and live in trees all the rest of their lives. But these animals are different. They do not need to climb trees so much now, for there is plenty of food near the ground, and very few enemies about from whom they must escape." "But," objected the Sun, "a time may come when there will not be any food near the ground, and who knows when some hungry beasts may wander into the valley and eat all your new creatures up?"
