When they sleep, the anthropoids sometimes lie stretched out, man-like, on their backs, and sometimes they lie on their side with their hand under their head for a pillow. The orang retires about five or six o’clock in the evening, and does not rise until the morning sun has dissipated the mists of the forest. The gorilla and chimpanzee seem to mate for life. The former lives, as a rule, in single families, each family consisting of a male and a female and their children. During the day this primitive family roams through the forests of equatorial Africa in search of food. They live on fruits and nuts and the tender shoots and leaves of plants. They are especially fond of sugar-cane, which they eat in small-boy fashion by chewing and discarding the juiceless pulp. Among the foods of the gorilla is a walnut-like nut which it cracks with stones. As evening comes on, the head of the family selects a sleeping-place for the night. This is usually some low tree with a dense growth at the top, and protected as much as possible by higher trees from the chilly night wind. Here, on a bed of broken branches and leaves, the mother and little ones go to sleep, while the father devotedly crouches at the foot of the tree, with his back against the trunk to guard his family from leopards and other nocturnal cut-throats who eat apes.[3] When the weather is stormy, they cover themselves with broad pandanus leaves to keep off the rain. Koppenfels relates an incident of a gorilla family which makes one think of things he sometimes sees among men. The family consisted of the parents and two children. It was meal-time. The head of the family reposed majestically on the ground, while the wife and children hustled for fruits for him in a near-by tree. If they were not sufficiently nimble about it, or if they were so wanton as to take a bite themselves, the paterfamilias growled and gave them a cuff on the head.[3] Notwithstanding the sensational tales of the ferocity of this being, the gorilla never attacks anyone at any time unless he is molested.[3] He much prefers to attend to his own business. But if he is not allowed to do so, if he is attacked, he is as fearless as a machine. He approaches his antagonist walking upright and beating his breast with his fists. He presents one of the most terrifying of all spectacles, as, with gleaming eyes, hair erect, and resounding yells, he bears down on the object of his resentment. The natives fear the gorilla more than they fear any other animal.
