The next morning we saw an old buffalo escorting his cow with two small calves over the prairie. Close behind came four or five large white wolves, sneaking stealthily through the long meadow-grass, and watching for the moment when one of the children should chance to lag behind his parents. The old bull kept well on his guard, and faced about now and then to keep the prowling ruffians at a distance.
As we approached our nooning-place, we saw five or six buffalo standing at the very summit of a tall bluff. Trotting forward to the spot where we meant to stop, I flung off my saddle and turned my horse loose. By making a circuit under cover of some rising ground, I reached the foot of the bluff unnoticed, and climbed up its steep side. Lying under the brow of the declivity, I prepared to fire at the buffalo, who stood on the flat surface about not five yards distant. The gleaming rifle-barrel levelled over the edge caught their notice, and they turned and ran. Close as they were, it was impossible to kill them when in that position, and stepping upon the summit I pursued them over the high arid table-land. It was extremely rugged and broken; a great sandy ravine was channeled through it, with smaller ravines entering on each side like tributary streams.
