Buffalo are the principal dependence of all the prairie tribes, both for food and clothing, and are hunted at all seasons; in the summer when the hair is light and short for clothing, lodges, etc., and in the winter, when it is long and heavy, for robes. There are three ways of hunting this animal: by surrounding, by approaching, and by the parks, each of which we will describe. It may as well be stated that the buffalo migrate, or take different ranges, and travel all in the same direction in a given season. Thus in the spring they mostly move north and northwest, in the fall east and south, in the winter east, returning west and north toward spring. They keep together in herds of from 100 or 200 to 5,000 or 6,000, and sometimes the whole country for five or six days travel is covered with one moving mass of these animals. News of the buffalo approaching an Indian camp is received several days before the animals appear, as they only move forward when the grazing is not sufficient. Where a large camp is stationed they usually hunt by “surround,” which is as follows: The soldiers hold a council with the chief in the soldiers’ lodge and prohibit any individual hunting ahead of the buffalo, also send runners daily on discovery, to observe what progress they are making toward the camp, their numbers, etc., and when they report them to be near enough a meeting is held in the soldiers’ lodge, the time for the hunt appointed, and notice given to the camp by the haranguing of the public crier. At daybreak all the horses are caught and saddled, and each of the horsemen is provided with a bow and a quiver of arrows. A number who have no horses arm themselves with guns, and at a signal from one of the soldiers the party moves off in single file or line. Those who have the fastest horses go in front, after them the other horsemen. Then the foot hunters, and lastly the women with their dogs and travailles. The soldiers ride along each side the line (which is sometimes a mile and more in length) and observe whether the line of march is preserved, and that no one leaves singly. Were a dog to run out of the line it would be shot with an arrow immediately. Their march is conducted in silence, with the wind in their faces, consequently blowing the scent away from the buffalo while they are coming near them. The animal is not quick sighted but very keen scented, and a man can, in passing across the wind blowing toward them, raise a herd at the distance of 2 or 3 miles, without their seeing him.
