After the incident had been closed, I gave the men a brief lecture on the language of bears, and the necessity of being able to recognize the distress call. You can chase bison, elephants and deer all day without hearing a single vocal utterance. They know through long experience the value of silence. The night after I shot my second elephant we noted an exception. The herd had been divided by our onslaught. Part of it had gone north, part of it south, and our camp for the night (beside the dead tusker) lay midway between the two. About bedtime the elephants began signalling to each other by trumpeting, and what they sounded was "The assembly." They called and answered repeatedly; and finally it became clear to my native followers that the two herds were advancing to unite, and were likely to meet in our vicinity. That particular trumpet call was different from any other I have ever heard. It was a regular "Hello" signal- call, entirely different from the "Tal-_loo_-e" blast which once came from a feeding herd and guided us to it. But it is only on rare occasions that elephants communicate with each other by sound. I once knew a general alarm to be communicated throughout a large herd by the sign language, and a retreat organized and carried out in absolute silence. Their danger signals to each other must have been made with their trunks and their ears; but we saw none of them, because all the animals were concealed from our view except when the two scouts of the herd were hunting for us. In captivity an elephant trumpets in protest, or through fear, or through rage; but I am obliged to confess that as yet I cannot positively distinguish one from the other. Once in the Zoological Park I heard our troublesome Indian elephant, Alice, roaring continuously as if in pain. It continued at such a rate that I hurried over to the Elephant House to investigate. And there I saw a droll spectacle. Keeper Richards had taken Alice out into her yard for exercise and had ordered her to follow him. And there he was disgustedly marching around the yard while Alice marched after him at an interval of ten paces, quite free and untrammeled, but all the while lustily trumpeting and roaring in indignant protest. The only point at which she was hurt was in her feelings. Two questions that came into public notice concerning the voices of two important American animals have been permanently settled by "the barnyard naturalists" of New York. The Voice of the American Bison. In 1907 the statement of George Catlin, to the effect that in the fall the bellowing of buffalo bulls on the plains resembled the muttering of distant thunder, was denied and severely criticized in a sportsman's magazine. On October 4 of that year, while we were selecting the fifteen bison to be presented to the Government, to found the Wichita National Bison Herd, four of us heard our best bull _bellow_ five times, while another did the same thing four times.
