There are but few elk or black-tailed deer in this region; and, as the common red deer secrete themselves in the bushes when alarmed, they are soon safe from the arrows of the Indian hunters, which are but feeble weapons against any animal which the huntsmen cannot previously run down. The chief game of the Shoshonees, therefore, is the antelope, which, when pursued, runs to the open plains, where the horses have full room for the chase. But such is this animal's extraordinary fleetness and wind, that a single horse has no chance of outrunning it, or tiring it down; and the hunters are therefore obliged to resort to stratagem. About twenty Indians, mounted on fine horses, and armed with bows and arrows, left the camp. In a short time, they descried a herd of ten antelopes. They immediately separated into little squads of two or three, and formed a scattered circle round the herd for five or six miles, keeping at a wary distance, so as not to alarm them till they were perfectly enclosed. Having gained their positions, a small party rode towards the herd; the huntsman preserving his seat with wonderful tenacity, and the horse his footing, as he ran at full speed over the hills, and down the ravines, and along the edges of precipices. They were soon outstripped by the antelopes, which, on gaining the other limit of the circle, were driven back, and pursued by fresh hunters. They turned, and flew, rather than ran, in another direction; but there, too, they found new enemies. In this way they were alternately driven backwards and forwards, till at length, notwithstanding the skill of the hunters, they all escaped; and the party, after running two hours, returned without having caught any thing, and their horses foaming with sweat. This chase, the greater part of which was seen from the camp, formed a beautiful scene; but to the hunters it is exceedingly laborious, and so unproductive, even when they are able to worry the animal down and shoot him, that forty or fifty hunters will sometimes be engaged for half a day without obtaining more than two or three antelopes. Soon after they returned, our two huntsmen came in with no better success. Capt. Lewis therefore made a little paste with the flour, and the addition of some berries formed a tolerable repast.
