Aboriginally the Siouan apparel was scanty, commonly comprising breechclout, moccasins, leggings, and robe, and consisted chiefly of dressed skins, though several of the tribes made simple fabrics of bast, rushes, and other vegetal substances. Fur robes and rush mats commonly served for bedding, some of the tribes using rude bedsteads. The buffalo-hunting prairie tribes depended largely for apparel, bedding, and habitations, as well as for food, on the great beast to whose comings and goings their movements were adjusted. Like other Indians, the Siouan hunters and their consorts quickly availed themselves of the white man’s stuffs, as well as his metal implements, and the primitive dress was soon modified. The woodland habitations were chiefly tent-shape structures of saplings covered with bark, rush mats, skins, or bushes; the prairie habitations were mainly earth lodges for winter and buffalo-skin tipis for summer. Among many of the tribes these domiciles, simple as they were, were constructed in accordance with an elaborate plan controlled by ritual. According to Morgan, the framework of the aboriginal Dakota house consisted of 13 poles;(33) and Dorsey describes the systematic grouping of the tipis belonging to different gentes and tribes. Sudatories were characteristic in most of the tribes, menstrual lodges were common, and most of the more sedentary tribes had council houses or other communal structures. The Siouan domiciles were thus adapted with remarkable closeness to the daily habits and environment of the tribesmen, while at the same time they reflected the complex social organization growing out of their prescriptorial status and militant disposition. Most of the Siouan men, women, and children were fine swimmers, though they did not compare well with neighboring tribes as makers and managers of water craft. The Dakota women made coracles of buffalo hides, in which they transported themselves and their householdry, but the use of these and other craft seems to have been regarded as little better than a feminine weakness. Other tribes were better boatmen; for the Siouan Indian generally preferred land travel to journeying by water, and avoided the burden of vehicles by which his ever-varying movements in pursuit of game or in waylaying and evading enemies would have been limited and handicapped.
