Look along on the wall until you find the pictures numbered 504, 505, 506 and 507. In these, by a series of tableaux, the painter presents to us the annual ceremony of initiation, called the Sun dance by the modern Dakotas, and witnessed two years ago by Miss Alice Fletcher. This ceremony continues four days and nights in succession, in commemoration of the subsiding of the flood, and also for the purpose of conducting all the young men, as they arrive at manhood, through an ordeal of voluntary torture, which when endured entitles them to the respect of the chiefs, to the privileges of going on war-parties, and of taking a wife. The floor and sides of the medicine lodge are ornamented with green willow boughs. The young men who are to do penance by torture lie along the sides of the lodge, their bodies covered with clay of different colors, their respective shields and weapons hanging over their heads. In the middle of the lodge the medicine man prays to the Great Spirit and watches the young men through their four days’ fast, preparatory to the torture. Near the medicine man lies a scalping knife, and a bunch of splints which are to be passed through the flesh of the novitiates like belaying pins. The Buffalo dance takes place several times each day outside the lodge in which the young men lie. The principal actors in this dance are eight men with the skins of buffaloes around them and a bunch of green willows on their backs. The evil spirit, Okeehedee, enters the village from the prairie, alarming the women, who cry for assistance and are relieved by the old medicine man. Okeehedee is at length disarmed of his lance, which is broken by the women, and he is driven by them in disgrace out of the village. On the fourth day of the festival the young men are subjected to the torture, which in many forms amounts essentially to this: Two gashes, parallel and near together, are cut quite through the skin, either on the breast, back or arms, looking for all the world like those on the sides of a sheep dressed for market. A wooden pin is thrust from gash to gash, under the intervening strip of skin. One end of a long and strong rawhide line is wrapped or belayed around this peg securely. Now comes the tug of war, the problem always being either to tear this peg out by breaking the strip of flesh or to see how much pain the sufferer can stand. He is hauled up to the roof of the lodge, suspended from an elastic sapling, or dragged around the camp; finally having fastened the end of the line farthest from him to a post, he tugs away with might and main until his flesh is torn loose.
