In his "Explorations and Adventures in Equatorial Africa" du Chaillu gives an equally thrilling account of the capture of his first gorilla. He says: "We started early, and pushed through the most dense and impenetrable part of the forest; in hopes to find the very home of the beast I so much wished to shoot. Hour after hour we travelled and yet no signs of gorillas. Only the everlasting, little, chattering monkeys--and not many of these--and occasionally birds. Suddenly Miengai uttered a little cluck with his tongue which is the native way of showing that something is stirring and that a sharp look-out is necessary. And presently I noticed, ahead of us seemingly, a noise as of some one breaking down branches or twigs of trees. This was a gorilla--I knew at once by the eager satisfied looks of the men. We walked with the greatest care making no noise at all. Suddenly, as we were yet creeping along, in a silence which made a heavy breath seem loud and distinct, the woods were at once filled with the tremendous barking roar of the gorilla. Then the underbrush swayed rapidly just ahead, and presently before us stood an immense male gorilla. He had gone through the jungle on all fours; but when he saw our party he erected himself and looked us boldly in the face. He stood about a dozen yards from us, and was a sight I think I shall never forget. Nearly six feet high (he proved four inches shorter), with immense body, huge chest, and great muscular arms, with fiercely glaring, large, deep gray eyes, and a hellish expression of face, which seemed to me like some nightmare vision: thus stood before us this king of the African forest. He was not afraid of us. He stood there and beat his breast with his huge fists till it resounded like an immense bass-drum, which is the gorillas' mode of offering defiance; meantime giving vent to roar after roar. The roar of the gorilla is the most singular and awful noise heard in these African woods. It begins with a sharp _bark_, like an angry dog, then glides into a deep bass _roll_, which literally and closely resembles the roll of distant thunder along the sky. So deep is it that it seems to proceed less from the mouth and throat than from the deep chest and vast paunch. His eyes began to flash fiercer fire as we stood motionless on the defensive, and the crest of short hair which stands on his forehead began to twitch rapidly up and down, while his powerful fangs were shown as he again sent forth his thunderous roar. He advanced a few steps--then stopped to utter that hideous roar again--advanced again, and finally stopped when at a distance of about six yards from us. And here, just as he began another of his roars, beating his breast with rage, we fired, and killed him. With a groan which had something terribly human in it, and yet was full of brutishness, he fell forward on his face. The body shook convulsively for a few minutes, the limbs moved about in a struggling way, and then all was quiet: death had done its work, and I had leisure to examine the huge body. It proved to be five feet eight inches high, and the muscular development of the arms and breast showed what immense strength it had possessed." A smaller gorilla, shot by M. du Chaillu on another occasion, measured five feet six inches in height, fifty inches round the chest, and his arms had a spread of seven feet two inches.
