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.
