These sudatories are always near the village, above or below it, on the bank of the river. They are generally built of skins (in form of a Crow or Sioux lodge which I have before described), covered with buffalo skins sewed tight together, with a kind of furnace in the centre; or in other words, in the centre of the lodge are two walls of stone about six feet long and two and a half apart, and about three feet high; across and over this space, between the two walls, are laid a number of round sticks, on which the bathing crib is placed (vide +plate+ 71). Contiguous to the lodge, and outside of it, is a little furnace something similar, in the side of the bank, where the woman kindles a hot fire, and heats to a red heat a number of large stones, which are kept at these places for this particular purpose; and having them all in readiness, she goes home or sends word to inform her husband or other one who is waiting, that all is ready; when he makes his appearance entirely naked, though with a large buffalo robe wrapped around him. He then enters the lodge and places himself in the crib or basket, either on his back or in a sitting posture (the latter of which is generally preferred), with his back towards the door of the lodge; when the squaw brings in a large stone red hot, between two sticks (lashed together somewhat in the form of a pair of tongs) and, placing it under him, throws cold water upon it, which raises a profusion of vapour about him. He is at once enveloped in a cloud of steam, and a woman or child will sit at a little distance and continue to dash water upon the stone, whilst the matron of the lodge is out, and preparing to make her appearance with another heated stone: or he will sit and dip from a wooden bowl, with a ladle made of the mountain-sheep’s horn, and throw upon the heated stones, with his own hands, the water which he is drawing through his lungs and pores, in the next moment, in the most delectable and exhilarating vapours, as it distils through the mat of wild sage and other medicinal and aromatic herbs, which he has strewed over the bottom of his basket, and on which he reclines.
