On reconnoitering the respective groups it became evident that we could not reach the cows without first breaking through the herd of bulls, and this we prepared to do at once. Riding slowly up so as not to alarm them, we approached within a few hundred yards of them before they took much notice of us. Then they ceased feeding and commenced bellowing furiously. At this the signal was given, and our fleet ponies were spurred rapidly towards the herd. When close to them, each hunter singled out a buffalo, and dashing impetuously past the animal, discharged an arrow into its neck. Those whose arrows did not fatally wound the beasts were at once exposed to imminent danger, as nothing exceeds a wounded buffalo in ferocity and strength. Rising for a moment on their hind feet, they dash furiously at the hunters, butting at them, and attempting to upset horse and man. Sometimes they succeed, and then the hunter suffers terrible wounds, if not death, from the horns of the enraged animal. Five or six bulls were killed in the attack, and the rest scattered widely over the prairie. The sight of the immense herd of cows in the distance excited the hunters, and prevented them from stopping to make any use of the bulls we had killed. We rode forward at a moderate speed for some distance, reserving the strength of our horses until we should be compelled to use their speed. At length the scouts of the herd saw us advancing, and in two or three seconds the whole herd was in motion. The first movements of the buffalo are slow, increasing in speed as they go. At the first symptoms of alarm our party raised a shout to encourage the horses, and we were suddenly flying along at full speed, the horses as much excited as their riders. The excitement was intense. At last we were close to them, and the arrows flew thick and fast into the herd. In a few moments we were in the midst of the press, firing arrows and using spears among the animals right and left. The scene was full of wild excitement and not without danger. Some of our party were thrown from their horses and suffered severe bruises and wounds from the feet and horns of the enraged buffaloes. At last the signal of recall was given, and our party reined up to rest from the chase and dispose of the spoils.
