THE CHALLENGE OF A BULL 173 The ‘‘ rutting”? season was in full swing, there were bulls frequently to be heard sounding their challenges, even during the middle of the day, and, as we trudged along to rest our leg-weary horses, we had been passing the time by whistling answers to the challenges, and also by tinkling a small horse-bell: the latter seemed particularly to rouse the deer’s ire. We had not gone out of our way to look for the animals themselves, though we had chanced on several cows and a couple of bulls, one of which carried a nice set of horns, though nothing out of the ordinary. Then, towards afternoon, we were attracted by the call of a bull that sounded exceptionally loud and harsh. He seemed to be coming in our direction, so we took our horses back from the creek into the timber and tied them up where they could not see or be seen. Then we watched for the advent of what we expected would be an extra large beast. You must now be told that the challenge of a bull wapiti is hard to describe; it is quite different from that of moose or red deer. It varies according to the age of the animal, but they all begin with from three to five flute-like notes, the first being low and the others ascending the scale. Young bulls whose voices are not fully developed usually have to content themselves with these few notes, but as they attain greater age their voices develop and they increase the length of the call with more lower notes. Old bulls give the finale with a regular deep bray, which can be heard a long distanee. By the length and harshness of the bray it is often possible to make a fair estimate of the size and age of the beast. Hardly had we left our horses and returned to the edge of the bank than a lone cow hove into view. She was striding along at a fast rate, right up the middle of the river bed and coming directly towards us. When we first saw ber she was about three hundred yards away. Then, when the cow had cut the distance between us in two, along came the finest bull it has ever been my good fortune to lay eyes on. He was rolling fat ; his brownish, cream-coloured body, with its lighter coloured rump
