The gorilla family of one adult male and a number of females and their young practically constitutes within itself a nation. There do not appear to be any social relations between different families, but within the same household there is apparent harmony. The gorilla is nomadic and rarely ever spends two nights in the same place. Each family roams about from place to place in the bush in search of food, and wherever they may be when night comes on, there they select a place to sleep. The largest family of gorillas that I ever heard of was estimated to contain twenty members. The usual number is rarely ever more than ten or twelve. The chimpanzees appear to go in somewhat larger groups than these. Sometimes in a single group of chimpanzees as many as three, or even four, adult males have been seen. When the young gorilla approaches the adult state he leaves the family group, finds himself a mate, and sets out in the world for himself. I observe that, as a rule, when one gorilla is seen alone in the forest it is usually a young male about reaching the state of manhood. It is probable that he has then set out for himself, and that he is in search of a wife. When two only are seen together they usually prove to be a young male and a young female. It sometimes occurs that three adults are seen with two or three children. In large families are seen young ones of different ages, from one year old to five or six years old. The older children are always fewer in number than the younger ones. I have once seen a large female quite alone except for her babe. Whether she lived alone or was only temporarily absent from her family I had no means of ascertaining. The gorilla chief does not provide food for his family. On the contrary, it is said that they provide for him. I have been informed, on two occasions and from different sources, that the gorilla chief has been seen sitting quietly eating under the shade of a tree while the others collected and brought to him his food. I have never myself witnessed such a scene, but it seems probable that the same story coming from two sources has some foundation of fact.
