At length I urged my horse close behind a bull, and after trying in vain, by blows and spurring, to bring him alongside, I shot a bullet into the buffalo from this disadvantageous position. At the report, Pontiac swerved so much that I was again thrown a little behind the game. The bullet, entering too much in the rear, failed to disable the bull, for a buffalo requires to be shot at particular points, or he will certainly escape. The herd ran up a hill, and I followed in pursuit. As Pontiac rushed headlong down on the other side, I saw Shaw and Henry descending the hollow on the right, at a leisurely gallop; and in front, the buffalo were just disappearing behind the crest of the next hill, their short tails erect, and their hoofs twinkling through a cloud of dust. At that moment, I heard Shaw and Henry shouting to me; but the muscles of a stronger arm than mine could not have checked at once the furious course of Pontiac, whose mouth was as insensible as leather. Added to this, I rode him that morning with a common snaffle, having the day before, for the benefit of my other horse, unbuckled from my bridle the curb which I ordinarily used. A stronger and hardier brute never trod the prairie; but the novel sight of the buffalo filled him with terror, and when at full speed he was almost uncontrollable. Gaining the top of the ridge, I saw nothing of the buffalo; they had all vanished amid the intricacies of the hills and hollows. Reloading my pistols, in the best way I could, I galloped on until I saw them again scuttling along at the base of the hill, their panic somewhat abated. Down went old Pontiac among them, scattering them to the right and left, and then we had another long chase.
