"Yet though tamed and made to know his master, he has, as we have seen, broken loose again in almost all parts of the world--in America on the prairies and pampas, in Europe and Asia on the steppes, and in Australia in the bush. And even in Great Britain, where so few patches of uncultivated land still remain, the young colts of Dartmoor, Exmoor, and Shetland, though born of domesticated mothers, seem to assert their descent from wild and free ancestors as they throw out their heels and toss up their heads with a shrill neigh, and fly against the wind with streaming manes and outstretched tails as the kulan, the tarpan, and the zebra do in the wild desert or grassy plain." CHAPTER XVII THE ELEPHANTS, RHINOCEROSES, HIPPOPOTAMUSES, AND WILD SWINE There are three reasons, perhaps, why elephants interest us so greatly. The first is their enormous size. They are by far the largest of all the animals which live upon land. "Jumbo," for instance, the famous African elephant that we in the United States saw in the last century, was nearly twelve feet in height, and weighed more than six tons. A height of ten feet is quite common. Next, there is their wonderful docility. When wild, no doubt, they are often very fierce and savage. Yet they are easily tamed; and it is a strange sight to see one of these giant creatures walking about with a load of children upon its back, and meekly obeying the lightest word of a man whom it could crush to death in a moment by simply placing its foot upon him. And then, once more, there is that marvelous trunk, so strong that it can tear down great branches from the trees, and yet so delicate that it can pick up the smallest scrap of food from the ground. When the elephant wishes to feed, it seizes the food with its trunk and pokes it into its mouth. When it wishes to drink, it fills the same organ with water, and then squirts the contents down its throat. If it should be hot, it can take a shower-bath by squirting water over its body instead. And it breathes through its trunk and smells with it as well. So this wonderful member is used for a great many different purposes. As it is so valuable, the elephant takes very great care of its trunk, always curling it up out of harm's way, for example, if it should find itself in any danger. Two different kinds of elephants are known, one of which is found in Africa and the other in Asia. THE AFRICAN ELEPHANT
