Wild animals abound through these jungles, and the spoor lasts long upon the crisp gravelly soil. In some districts they visit by night the raised clay water-troughs of the cultivators. The elephant prefers the thick jungle, where he can wallow in the pools and feed delicately upon succulent roots and fruits, bark, and leaves. The rhinoceros loves the dark clumps of trees, which guard him from the noonday sun, and whence he can sally out all unexpected upon the assailant. The mbogo, or Bos Caffer, driven from his favourite spots, low grassy plains bordering on streams, wanders, like the giraffe, through the thinner forests. As in Unyamwezi, the roar of the lion strikes the ear by night, and the cry of the ostrich by day. The lion upon this line of Eastern Africa is often heard, but rarely seen; on only two occasions its footprints appeared upon the road. The king of beasts, according to the Arabs, is of moderate stature: it seldom attains its maximum of strength, stature, and courage, except in plain countries where game abounds, as in the lands north of the Cape, or in hills and mountains, where cattle can be lifted at discretion, as in Northern Africa. In Unyamwezi its spoils, which are yellow, like those of the Arab lion, with a long mane, said to hang over the eyes, and with a whitish tinge under the jaws, become the property of the Sultan. The animal is more common in the high lands of Karagwah than in the low countries; it has, however, attacked the mbogo, or wild bull, and has destroyed cattle within sight of the Arabs at Kazeh in Unyanyembe. The lion is rarely a man-eater; this peculiarity, according to some writers, being confined to old beasts, whose worn teeth are unfit for fight.
