One day I had been for a stroll with Moses and the boy. As we returned to the cage we saw a chimpanzee about half-grown; he was crossing the rugged little path about thirty yards away from us. He paused for a moment to look at us, and we stopped. I tried to induce Moses to call out to him, but he declined to do so. As the stranger turned aside I called to him myself, but he neither stopped nor answered. This one appeared to be quite brown, but the boy assured me his hair was jet black, but his skin being light gave him this colour. To satisfy myself, I had Moses placed in the same place and position, and looking at him from the same distance I was convinced that the boy was right.
One morning, as I started with Moses for a walk, I had only gone some forty yards away from the cage when he made a sound of warning. I instantly looked up, when I saw a large chimpanzee standing in the bush not more than twenty yards away. I paused to look at him. He stood for a moment, looking straight at us. I spoke to him, but he made no reply; he moved off almost parallel to the little path which we were in, and I returned towards the cage. He did not come any nearer to us, but kept his course almost parallel with ours. He turned his head from time to time to look, but gave no sign of attack. I called to him several times, but he made no answer. When I reached a place in front of the cage I called again, and after the lapse of a few seconds he stopped. By this time he was concealed from view. He only halted for a moment, changed his course and resumed his journey. This was the largest one I saw in the forest.
At another time, while sitting in the cage, I heard the sound of something making its way through the bush not more than twenty yards away; presently it passed in view. As it crossed the path near by, I called three or four times, but it neither stopped nor answered. As well as I could tell, it appeared to be a female and quite grown.
I may take occasion to remark that while the chimpanzee is mostly found in large family groups, as I have reason to believe from native accounts of them, and from what has been told me by white men, I have never been able to see a family of them together, but each of these that I have mentioned, so far as I could tell, was quite alone. Whether the others were scattered through the forest in like manner, hunting for food, and all came together after this or not, I can only say that every chimpanzee that I saw was alone at the time.
Another thing worthy of mention is the fact that both these apes live in the same forest, and twice on the same day I have seen both kinds. This is contrary to the common idea that they do not inhabit the same jungle. It appears that where there is a great number of the one there are but few of the other. The natives say that in combat between the chimpanzee and gorilla, the former is always victor, on which account the latter is afraid of him. I believe this to be true, because the chimpanzee, although not so strong, is more active and more intelligent than the gorilla.
The chimpanzee will not approach or attack man if he can avoid it, but he does not shrink from him as the gorilla does. One instance that will illustrate this phase of his character I shall relate. On one occasion recently, while I was on the coast, a native boy started across a small plain near the trading station. Along with him was a dog that belonged to the white trader at the place. The dog was in advance of the boy, and as the latter emerged from a small clump of the bush he heard the dog bark in a playful manner, and discovered him not more than thirty yards away, prancing, jumping, and barking in a jolly way with a chimpanzee which appeared to be five or six years old. The ape was standing in the path along which the boy was proceeding. He was slapping at the dog with his hands, and did not seem to relish the sport, yet he was not resenting it in anger. The dog thought the ape was playing with him, and he was taking the whole thing in fun. The boy looked at them for a few moments and retreated. As soon as he disappeared the dog desisted and followed him to the house. The boy was afraid of the ape, and made no attempt to capture him. The latter was taken by surprise by the dog and boy, and thus had no time to escape. He did not strike to harm the dog, but only to ward him off. The dog made no attempt to bite him, but when he would jump up against him he would knock the ape out of balance, and this annoyed him. He didn't seem to understand just what the dog meant.
I shall not describe those so well known in captivity, only to mention some of them. The largest specimen of the chimpanzee that I have ever seen was Chico, who belonged to Mr. James A. Bailey, of New York. He was as large perhaps as these apes ever become, although he was less than ten years old when he died.
Perhaps the most valuable specimen for scientific use that has ever been in captivity is Johanna, who belongs to the same gentleman. The history that is given of her, however, is hardly to be taken in full faith. Her age cannot be determined with certainty, but it is said that she is about thirteen years old. I have reason to doubt that, although I cannot positively deny it. Whatever may be her exact age, it is certain that she has now reached a complete adult state. She has grown to be quite as large as Chico was at the time of his death. She is not of amiable temper, but is much less vicious than he was. She has some of the marks of a kulu kamba.
In order to justify my doubts upon the subject of her age, I may state that Chico was only ten years of age when he died, but had reached the adult period; and as males do not reach that state sooner than the females of any genus of the primates, it is not probable that he was mature at ten, while she was not so until twelve. In the next place, her captors claim to have seen her within a few hours after her birth, and that they watched her and her mother from time to time until she was one year old, when they killed the mother and captured the babe. The claim is absurd. These apes are nomadic in habit, and are rarely ever seen in the same place. They claim that she was born on January 19, but from what I know of these apes that is not their season of bearing, and I doubt if any of them were ever born during that month. Again, it is claimed that she was captured by Portuguese explorers in the Congo, but the Portuguese do not possess any territory along that river in which these apes are ever found. They claim the territory around Kabenda, which would indicate that she came from the Loango Valley instead of the Congo, but the cupidity of the average Portuguese would never allow anything to go at liberty for a year if it could be sold before that time.
Johanna is accredited with a great deal of intelligence; but I do not regard her as being above the average of her race. Since the death of her companion, Chico, she has received the sole attention of her keeper, and since that time has been taught a few things which are neither marvellous nor difficult. In point of intellect she cannot be regarded as an extraordinary specimen of her tribe. I do not mean to detract from her reputation, but I have failed to discover in her any high order of mental qualities.
