These horses are so trained, that the Indian has little use for the rein, which hangs on the neck, whilst the horse approaches the animal on the right side (+plate+ 107), giving his rider the chance to throw his arrow to the left; which he does at the instant when the horse is passing—bringing him opposite to the heart, which receives the deadly weapon “to the feather.” When pursuing a large herd, the Indian generally rides close in the rear, until he selects the animal he wishes to kill, which he separates from the throng as soon as he can, by dashing his horse between it and the herd, and forcing it off by itself; where he can approach it without the danger of being trampled to death, to which he is often liable by too closely escorting the multitude. In +plate+ 107, I have fairly represented the mode of _approaching_, at the instant the arrow is to be thrown; and the striking disparity between the size of a huge bull of 2000 pounds weight, and the Indian horse, which, it will be borne in mind, is but a pony. No bridle whatever is used in this country by the Indians, as they have no knowledge of a bit. A short halter, however, which answers in place of a bridle, is in general use; of which they usually form a noose around the under jaw of the horse, by which they get great power over the animal; and which they use generally to _stop_ rather than _guide_ the horse. This halter is called by the French Traders in the country, _l’arrêt_, the stop, and has great power in arresting the speed of a horse; though it is extremely dangerous to use too freely as a guide, interfering too much with the freedom of his limbs, for the certainty of his feet and security of his rider.
