On the second day of our stay at this place, Henry went out for an afternoon hunt. Shaw and I remained in camp until, observing some bulls approaching the water from the other side of the river, we crossed over to attack them. They were so near, however, that before we could get under cover of the bank our appearance as we walked over the sands alarmed them. Turning round before coming within gunshot, they began to move off to the right in a direction parallel to the river. I climbed up the bank and ran after them. They were walking swiftly, and before I could come within gunshot distance they slowly wheeled about and faced toward me. Before they had turned far enough to see me I had fallen flat on my face. For a moment they stood and stared at the strange object upon the grass; then turning away, again they walked on as before; and I, rising immediately ran once more in pursuit. Again they wheeled about, and again I fell prostrate. Repeating this three or four times, I came at length within a hundred yards of the fugitives, and as I saw them turning again I sat down and leveled my rifle. The one in the center was the largest I had ever seen. I shot him behind the shoulder. His two companions ran off. He attempted to follow, but soon came to a stand, and at length lay down as quietly as an ox chewing the cud. Cautiously approaching him, I saw by his dull and jellylike eye that he was dead. When I began the chase, the prairie was almost tenantless; but a great multitude of buffalo had suddenly thronged upon it, and looking up, I saw within fifty rods a heavy, dark column stretching to the right and left as far as I could see. I walked toward them. My approach did not alarm them in the least. The column itself consisted entirely of cows and calves, but a great many old bulls were ranging about the prairie on its flank, and as I drew near they faced toward me with such a shaggy and ferocious look that I thought it best to proceed no farther. Indeed, I was already within close rifle-shot of the column, and I sat down on the ground to watch their movements. Sometimes the whole would stand still, their heads all facing one way; then they would trot forward, as if by common impulse, their hoofs and horns clattering together as they moved. I soon began to hear at a distance on the left the sharp reports of a rifle, again and again repeated; and not long after, dull and heavy sounds succeeded, which I recognized as the familiar voice of Shaw's double-barreled gun. When Henry's rifle was at work there was always meat to be brought in. I went back across the river for a horse, and returning, reached the spot where the hunters were standing. The buffalo were visible on the distant prairie. The living had retreated from the ground, but ten or twelve carcasses were scattered in various directions. Henry, knife in hand, was stooping over a dead cow, cutting away the best and fattest of the meat.
