unshaken, and kept drifting steadily southward. It began to look as if, in spite of Fate, a mighty remnant would yet make good its way into the broken country, dangerous with hostile Indians, whither the white hunters would hesitate to pursue. It was decided, therefore, to check the southward march of the host by splitting it up into sections and scattering it to this side and that, thus depriving it of the united migrant impulse, and leaving its destruction to be completed at more leisure.

These men knew the bison and his deep-rooted habits. In knots of three and four they stationed themselves, on their ponies, directly in the path of the advancing host.

On the flanks they attracted small attention. But directly in front, the sight of them aroused the leaders of the march to fury. They pawed the ground, snorted noisily, and then charged with their massive heads low down. And the whole host, with sudden rising rage, charged with them. It looked as if those little knots of waiting men and ponies must be annihilated.

But when that dark, awful torrent of rolling manes, wild eyes, keen horns, and shattering hoofs drew close upon the waiting groups of men, these lifted their guns and fired, one after the other, straight in the faces of the nearest bulls.

The result was instantaneous, as usual. Whether, as in most cases, the leaders fell, or, as in other instances, they escaped, the rolling torrent split and parted at once to either side as if the flame and roar from the muzzles of the guns had been so many shoulders of rock. Once divided, and panic-stricken by finding their foes at the heart of their array, the herds went to pieces hopelessly, and were easily driven off toward all points of the compass.

But in one instance—just one—the plan of the slaughterers did not work out quite as anticipated.

Three of the hunters had taken station exactly opposite the center of the host. Brown Bull and his herd were immediately behind the front rank at this point. When the great charge was met by the roar and the spirting flames, the leading bull went down, and the front rank split, as a matter of course, to pass on either side of this terrifying obstacle. But Brown Bull seemed to feel that here and now, straight before him, was the unknown peril which had been shaking his heart throughout the whole long march. In this moment his heart was no more shaken, and the tradition of his ancestors, which bade him follow his leaders like a sheep, was torn up by the roots. He did not swerve, but swept down straight upon the astonished knot of horsemen; his trusting herd came with him; and all behind, as usual, followed blindly.
