Still we went on, the animals being too busily engaged in grazing, or in attacking each other, to observe us. At last the Indian advised that we should halt behind a knoll which rose out of the plain, with a few bushes on the summit. Here we could remain concealed from the herd. So, having gained the foot of the knoll, we dismounted; and leaving our horses in charge of the men with the cart, my father and I climbed up to the top, where by crouching down we were unseen by the herd, although we could observe all that was going forward. The Indian hunters now took some wolf-skins which had been hanging to their saddles, and completely covering themselves up, so as to represent wolves, they began to creep towards the herd, trailing their rifles at their sides; thus they got nearer and nearer the herd. Whenever any of the animals stopped to look at them, they stopped also; when the buffalo went on feeding, they advanced. At length each hunter, having selected a cow, suddenly sprang to his knees and fired, and three fine animals rolled over; though, had the buffalo bulls known their power, they might, with the greatest ease, have crushed their human foes. On hearing the shots, the whole herd took to flight. "Well done!" cried my father. "I should like to have another, though;" and hurrying down the hill, he mounted his horse and galloped off in chase of the retreating herd. Heavy and clumsy as the animals looked, so rapidly did they rush over the ground that he could only got within range of two or three of the rearmost. Pulling up, he fired; but the buffalo dashed on; and, unwilling to fatigue his horse, my father came back, somewhat annoyed at his failure. The three animals which had been killed were quickly cut up, and we loaded our cart with the meat; after which the Indians accompanied us back to the camp to receive the reward we had promised. The supply of fresh meat was very welcome, and helped to keep sickness at a distance for some time longer. After this we made several days' journey, the supply of fresh provisions putting all hands into better spirits than they had shown for some time. There was but little chance, however, of our replenishing our stock when that was exhausted, for we saw Indians frequently hovering round our camp who were not likely to prove as friendly as those we had before met with, and it would be dangerous to go to any distance in search of game, as there was a probability of our being cut off by them. We had soon another enemy to contend with, more subtile than even the Redskins. Cholera broke out among the emigrants, and one after another succumbed. This determined those who had before talked of going back to carry out their intentions; and notwithstanding the expostulations of my father and others, they turned round the heads of their cattle, and back they went over the road we had come.
