Annually, in the month of July, the Minnetarees celebrate their great medicine dance, or dance of penitence, which may well be compared with the Currack-pooja of the expiatory tortures of the Hindoos, so often celebrated at Calcutta. On this occasion a considerable quantity of food is prepared, which is well cooked, and served up in their best manner. The devotees then dance and sing to their music at intervals, for three or four days together in full view of the victuals, without attempting to taste of them. But they do not, even at this time, forego {255} their accustomed hospitality. And if a stranger enters, he is invited to eat, though no one partakes with him. On the third or fourth day, the severer expiatory tortures commence, to which the preceding ceremonies were but preludes. An individual presents himself before one of the officiating magi, crying and lamenting, and requests him to cut a fillet of skin from his arm, which he extends for that purpose. The devout operator thrusts a sharp instrument through the skin near the wrist, then introduces the knife, and cuts out a piece of the required length, sometimes extending the excision entirely to the shoulder. Another will request bands of skin to be cut from his arm. A third will have his breast flayed, so as to represent a full moon or crescent. A fourth submits to the removal of concentric arcs of skin from his breast. A fifth prays the operator to remove small pieces of skin from various indicated parts of his body; for this purpose an iron bodkin is thrust through the skin, and the piece is cut off, by passing the knife under the instrument. Various are the forms of suffering which they inflict upon themselves. An individual requests the operator to pierce a hole through the skin of each of his shoulders, and after passing a long cord through each of these holes, he repairs to a Golgotha at some distance from the village, and selects one of the bison skulls collected there. To the chosen cranium he affixes the ends of his cords, and drags it in this painful manner to the lodge, round which he must go with his burden, before he can be released from it. No one is permitted to assist him, neither dares he to put his own hands to the cords, to alleviate his sufferings. If it should so happen that the horns of the cranium get hooked under a root or other obstacle, he must extricate it in the best manner he can, by pulling different ways, but he must not touch the rope or the head with his hands, or in any respect attempt to relieve the painful strain upon his wounds, until his complete task is performed. {256} Some of the penitents have arrows thrust through various muscular parts of their bodies, as through the skin and superficial muscles of the arm, leg, breast, and back.
