In the beginning of his career of independent life the young gorilla selects a wife with whom thereafter he appears to sustain the conjugal relation, and he maintains a certain degree of marital fidelity. From time to time he adopts a new wife, but does not discard the old one. In this manner he gathers around him a numerous family, consisting of his wives and children. Each mother nurses and cares for her own young, but all of them grow up together as the children of one family. The mother sometimes corrects and sometimes chastises her young. This presupposes some idea of propriety.
The father exercises the function of patriarch in the sense of a ruler, and the natives call him ikomba njina, which means “gorilla chief.” This term is derived from the third person singular of the verb kamba, “to speak”—i kamba, “he speaks.” Hence “spokesman,” or one that speaks for others. To him all the others show a certain amount of deference. Whether this is due to fear or respect is not certain; but here is at least the first principle of dignity.
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.
In the matter of government the gorilla appears to be somewhat more advanced than most animals. The chief leads the others on the march and selects their feeding grounds and their places to sleep. He breaks camp, and the others all obey him in these respects. Other gregarious animals do the same, but, in addition to these things, the gorillas from time to time hold a rude form of court, or council, in the jungle. It is said that the king presides on these occasions; that he sits alone in the center, while the others stand or sit in a semicircle about him and talk in an excited manner. Sometimes all of them are talking at once. Many of the natives claim to have witnessed these proceedings; but what they mean or allude to no native undertakes to say, except that there appears to be something of the nature of a quarrel. To what extent the chief gorilla exercises the judicial function is a matter of doubt, but there appears to be some real ground for the story.
As to the succession of the kingship there is no authoritative information as yet to be had; but from the meager data upon this point the belief is that on the death of the ikomba if there be an adult male he assumes the royal prerogative; otherwise the family disbands and eventually becomes absorbed by or attached to other families. Whether this new leader is elected in the manner in which other animals appoint a leader, or assumes it by reason of his age, cannot now be stated. There is no doubt that in many instances families remain intact for a long time after the death of their ikomba.
It has been stated by many writers that the gorilla builds a rude hut for himself and family. I have found no evidence that such is the fact. The natives declare that he does this, and some white men affirm the same. During my travels through the country of the gorilla I offered frequent and liberal rewards to any native who would show me a specimen of this simian architecture; but I was never able to find a trace of one made or occupied by any ape. Sometimes they take shelter from the tornadoes, but it is usually under some fallen tree or a cluster of broad leaves. There is absolutely nothing to indicate that they rearrange any part of tree or leaves. So far as I could find, there is absolutely no proof that any gorilla ever put two sticks together with the idea of building a shelter. As to his throwing sticks or stones at an enemy, there is nothing to verify it, but much to controvert it. It is a mere freak of fancy.
The current opinion that a gorilla will attack a man without being provoked to it is another popular error. He is shy and timid. He shrinks alike from man and from other large animals. When he is in a rage he is both fierce and powerful; but his ferocity and strength are rated above their value. In combat no doubt he is a stubborn foe, but no one I have ever met has seen him thus engaged. His mode of attack, as described by certain travelers, is a mere theory. It is said that in this act he walks erect, furiously beats upon his breast, roars, and yells. In this manner he first terrorizes and then seizes his adversary, tears open his breast and drinks the blood. I have never seen a large gorilla in the act of assault.
During my stay in the jungle I had a young gorilla in captivity. I made use of him in studying the habits of his race. I kept him tied with a long line which allowed him room to play or climb about in the bushes, and at the same time prevented him from escaping into the forest, as he always tried to do the instant he was released. I frequently released him for the purpose of watching his mode of attack when recaptured. While being pursued he rarely looked back, but when overtaken he invariably assailed his captor. This gave me an opportunity of seeing his method of attack. In this he displayed both skill and judgment. As my native boy approached him he calmly turned one side to the foe and, without facing the boy, rolled his eyes in such a manner as to see him and at the same time conceal his own purpose. When the boy came within reach, the gorilla grasped him by thrusting the arm to one side and obliquely backwards. When he had seized his adversary by the leg, he instantly swung the other arm around with a long sweep, so as to strike the boy a hard blow. Then he used his teeth. He seemed to depend more upon the blow than upon the grasp, but the latter served to hold the object of attack within reach. In every case he kept one arm and one leg in reserve until he had seized his adversary.
