shouldering each other along at a clumsy gallop.  We followed, spurring our horses to full speed; and as the herd rushed, crowding and trampling in terror through an opening in the hills, we were close at their heels, half suffocated by the clouds of dust.  But as we drew near, their alarm and speed increased; our horses showed signs of the utmost fear, bounding violently aside as we approached, and refusing to enter among the herd.  The buffalo now broke into several small bodies, scampering over the hills in different directions, and I lost sight of Shaw; neither of us knew where the other had gone.  Old Pontiac ran like a frantic elephant up hill and down hill, his ponderous hoofs striking the prairie like sledge-hammers.  He showed a curious mixture of eagerness and terror, straining to overtake the panic-stricken herd, but constantly recoiling in dismay as we drew near.  The fugitives, indeed, offered no very attractive spectacle, with their enormous size and weight, their shaggy manes and the tattered remnants of their last winter’s hair covering their backs in irregular shreds and patches, and flying off in the wind as they ran.  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 incontrollable.  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.  About a dozen bulls were before us, scouring over the hills, rushing down the declivities with tremendous weight and impetuosity, and then laboring with a weary
