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 a 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 the hair was jet black, and that the light skin gave the appearance of brown color. To satisfy myself, I had Moses placed in the same attitude and position, and, looking at him from the same distance, I became convinced that the boy was right. One morning, having started with Moses for a walk, we had gone only some forty yards away from the cage when he made a sound of warning. I instantly looked up and saw a large chimpanzee standing in the bush not more than twenty yards away. I paused to observe him. He stood for a moment, looking straight at us. I spoke to him, but he made no reply; he moved off in a line almost parallel to the little path 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. From time to time he turned his head to look, but gave no sign of attack. I called to him several times, but he made no answer. When I had 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 halted only for a moment, changed his course, and resumed his journey. This was the largest chimpanzee I saw in the forest. Once, while sitting in the cage, I heard the sound of something making its way through the bush not more than twenty yards away; presently a chimpanzee came into 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. Each of these that I have mentioned, so far as I could tell, was quite alone. Whether or not the others were scattered through the forest in like manner, hunting for food, and all came together after this, I cannot say.
