The most interesting to us are, of course, the man-like apes. Diard was told by the Malays, and he found it afterwards to be true, that the young Siamangs, when in their helpless state, are carried about by their parents, the males by the father, the females by the mother.[41] Lieutenant C. de Crespigny, who was wandering in the northern part of Borneo in 1870, gives the following description of the Orang-utan: “They live in families—the male, female, and a young one. On one occasion I found a family in which were two young ones, one of them much larger than the other, and I took this as a proof that the family tie had existed for at least two seasons. They build commodious nests in the trees which form their feeding-ground, and, so far as I could observe, the nests, which are well lined with dry leaves, are only occupied by the female and young, the male passing the night in the fork of the same or another tree in the vicinity. The nests are very numerous all over the forests, for they are not occupied above a few nights, the mias (or Orang-utan) leading a roving life.”[42] According to Dr. Mohnike, however, the old males generally live with the females during the rutting season only;[43] and Mr. Wallace never saw two full-grown animals together. But as he sometimes found not only females, but also males, accompanied by half-grown young ones,[44] we may take for granted that the offspring of the Orang-utan are not devoid of all paternal care. More unanimous are the statements which we have regarding the Gorilla. According to Dr. Savage, they live in bands, and all his informants agree in the assertion that but one adult male is seen in every band. “It is said that when the male is first seen he gives a terrific yell that resounds far and wide through the forest.... The females and young at the first cry quickly disappear; he then approaches the enemy in great fury, pouring out his horrid cries in quick succession.”[45] Again, Mr. Du Chaillu found “almost always one male with one female, though sometimes the old male wanders companionless;”[46] and Mr. Winwood Reade states likewise that the Gorilla goes “sometimes alone, sometimes accompanied by his female and young one.”[47] The same traveller was told that, when a family of Gorillas ascend a tree and eat a certain fruit, the old father remains seated at the foot of the tree. And when the female is pregnant, he builds a rude nest, usually about fifteen or twenty feet from the ground; here she is delivered, and the nest is then abandoned.[48]
