You can easily tell the African elephant by the great size of his ears, which are so large that a man might almost hide himself behind one of them. "Jumbo's" ear, indeed, measured no less than five feet five inches from side to side. When the animal is excited these enormous ears stand out at right angles to the head. Then the legs are much longer than those of the Indian elephant, while the trunk, instead of having one finger-like projection at the tip, has two, one in front and one behind. Both the male and female animal, as a rule, possess tusks, while in Indian elephants these weapons are only occasionally present in the male, and hardly ever in the female. The tusks of the male elephant, however, are always much larger than those of his mate, and sometimes they grow to a very great size. A length of nine feet is not very uncommon, while tusks ten feet long, or even more, have sometimes been recorded. Generally one tusk is several inches shorter than the other, having been worn down in digging for the roots on which the animal is fond of feeding; for elephants seem to dig with one of the tusks only, and never with both. The ivory of which these tusks are composed is so valuable that the African elephant has been most terribly persecuted, and in many districts where it was formerly plentiful it has disappeared altogether. It lives as a rule in herds, which seek the thickest parts of the forest during the day, and come out at night to search for food and water. And even a small herd of elephants will sometimes do a great deal of damage, for they will uproot trees eighteen or even twenty feet high, in order to feed upon the foliage of the upper branches, or snap off the stems quite close to the ground. When the tree is a large one, it is said that two elephants will unite in breaking it down. You would think that a herd of elephants would be very conspicuous even in the thick forest, wouldn't you? Yet all hunters unite in saying that as long as they remain still it is almost impossible to see them, while they make their way through the bushes so silently that even when they are moving it is not at all easy to hear them. THE INDIAN ELEPHANT This elephant seldom exceeds nine feet in height at the shoulder, although larger examples are sometimes found. It lives in the thick jungle in herds of forty or fifty, which sometimes wander by night into cultivated ground, and do terrible damage to the crops. Now and then, however, a male elephant will live entirely alone. These solitary animals are always very fierce, and will rush out and attack any one who may pass by. For this reason they are known as "rogues."
