The first one that I had the pleasure of seeing in the jungle came within a few yards of the cage before it was yet in order to receive. He was not half grown. He must have been attracted by the noise made in putting it together. He advanced with caution, and when I discovered him he was peering through the bushes as if to ascertain the cause of the sounds. When he saw me, he only tarried a few seconds and hurried off into the jungle. I did not disturb or shoot at him, because I desired him to return. On the third day after I went to live in the cage a family of ten gorillas was seen to cross an open space along the back of a patch of plantains near one of the villages. A small native boy was within about twenty yards of them when they crossed the path in front of him. A few minutes later I was notified of it, took my rifle, and followed them into the jungle until I lost the trail. A few hours after this they were again seen by some natives not far away from my cage, but they did not come near enough to be seen or heard. The next day there was a family came within some thirty yards of the cage. The bush was so dense that I could not see them, but I could distinguish four or five voices. They seemed to be engaged in a broil of some kind. I suppose it was the same family that had been seen the day before. The second night after this time I heard the screams of one in the forest some distance from me, but I do not know whether it was the king of this family or another. One day, as I sat alone, a young gorilla, perhaps five years old, came within six or seven yards of the cage and took a peep. I do not know whether he was aware of its being there or not until he was so near. He stood for a time, almost erect, with one hand holding on to a bough; his lower lip was relaxed, showing the red line mentioned above, and the end of his tongue could be seen between his parted lips. He did not evince either fear or anger, but rather appeared to be amazed. I heard him creeping through the bush a few seconds before I saw him, but as a rule they move so stealthily as not to be heard. I know of no other animal of equal weight that makes so little noise in going through the forest. During the short time he stood gazing at me I sat still as a statue, and I think he was in doubt as to whether I was alive or not. He did not turn and run away, but after a brief pause turned off at an angle and departed. He lost no time, but made no great haste. The only sound he made was a low grunt, and this he did not repeat.
