Another specimen that was brought aboard a ship when I was present was a young male, something less than two years old. He was sullen and morose. He did not resent my approaches, but he did not encourage them. I first spoke to him with the food sound, but he gave no heed. I retired a little distance from him and called him, but he paid no attention. I then used the sound of warning; he raised his head, and looked in the direction from which the sound came. I repeated it, and he looked at me for a moment and turned his head away. I repeated it again. He looked at me, then looked around as if to see what it meant, and again resumed his attitude of repose. On my last voyage to the coast I saw a very good specimen in the Congo. It was a female, a little more than two years old. She was also of a dark complexion, but quite intelligent. She had been captured north of there, and within the limits elsewhere described. At the time I saw her she was ill and under treatment, but her master, the British consul, told me that when she was well she was bright and sociable. I made no attempt to talk with her, except some time after, having left her, I gave the call sound, which she answered by looking around the corner of the house. I do not know whether she would have come or not, as she was tied and could not have done so had she desired to. I have seen a few other specimens of this ape, and most of them appear to be of a somewhat higher order than the ordinary chimpanzee, but there is among them a wide range of intelligence. It would be a risk to say whether the lowest specimen of kulu is higher or lower than the highest specimen of the common chimpanzee or not, but taken as a whole they are much superior. I shall not describe at length the specimens which have been known in captivity, since most of them have been amply described by others; but it is not out of place to mention some of them. If proper conditions were afforded to keep a pair of kulus in training for some years, it is difficult to say what they might not be taught. They are not only apt in learning what they are taught, but they are well-disposed, and can apply their accomplishment to some useful end. We cannot say to what extent they may be able to apply what they learn from man, because the necessity of doing so is removed by the attention given them. CHAPTER XIV GORILLAS
