"My horse was a trained hunter, famous in the west under the name of Proveau, and, with his eyes flashing, and the foam flying from his mouth, sprang on after the cow like a tiger. In a few moments he brought me alongside of her, and, rising in the stirrups, I fired at the distance of a yard, the ball entering at the termination of the long hair, and passing near the heart. She fell headlong at the report of the gun, and checking my horse, I looked around for my companions. At a little distance, Kit was on the ground, engaged in tying his horse to the horns of a cow which he was preparing to cut up. Among the scattered bands, at some distance below, I caught a glimpse of Maxwell; and while I was looking, a light wreath of white smoke curled away from his gun, from which I was too far to hear the report. Nearer, and between me and the hills, towards which they were directing their course, was the body of the herd, and giving my horse the rein, we dashed after them. A thick cloud of dust hung upon their rear, which filled my mouth and eyes, and nearly smothered me. In the midst of this I could see nothing, and the buffalo were not distinguishable until within thirty feet. They crowded together more densely still as I came upon them, and rushed along in such a compact body, that I could not obtain an entrance--the horse almost leaping upon them. In a few moments the mass divided to the right and left, the horns clattering with a noise heard above everything else, and my horse darted into the opening. Five or six bulls charged on us as we dashed along the line, but were left far behind, and singling out a cow, I gave her my fire, but struck too high. She gave a tremendous leap, and scoured on swifter than before. I reined up my horse, and the band swept on like a torrent, and left the place quiet and clear. Our chase had led us into dangerous ground. A prairie-dog village, so thickly settled that there were three or four holes in every twenty yards square, occupied the whole bottom for nearly two miles in length. Looking around, I saw only one of the hunters, nearly out of sight, and the long dark line of our caravan crawling along, three or four miles distant." The trail which the party left behind them now forms the emigrant road to California via Fort Laramie, Salt Lake, etc. On reaching Fort Laramie, Fremont found a fearful state of affairs existing among the Sioux Indians through whose country his route lay. An encounter had recently taken place between a war-party belonging to the Sioux nation and a party of trappers and Snake Indians. In the fight the Indians had been worsted and several of their braves killed. To revenge themselves the Sioux chieftains had collected their warriors; and, while the nation was encamped to the number of one thousand lodges, they had gone forth to seek and punish their enemies.
