The "war bonnet," worn by the leading warriors, was a headdress of skins and feathers, which trailed down the back and often to the ground, and was highly picturesque. Add to this, the general habit of tattooing, or, on ceremonial occasions, of fantastically, often hideously, painting the face and neck and breast in blue, black, and red, and one can well imagine that an Indian village, on a fête day, or at other times of popular excitement, presented a striking scene. Each tribe could be readily distinguished from others, by the shape and material of its wigwams or huts. The Chippewas, for instance, lived in hemispherical huts, covered with great sheets of birch-bark; the Winnebago hut was more of the shape of a sugar loaf, and was covered with mats of woven rushes; the Sioux dwelt in cone-shaped huts (_tepees_), covered with skins, the poles sticking out at the top. These huts were foully kept, and all manner of camp diseases prevailed; pulmonary complaints and rheumatism were particularly frequent, and both men and women looked old and haggard before they reached middle age. In the old mound building days, the huts of the village leaders or chiefs were no doubt built upon the tops of the mounds, while the common people lived on the lower level. On top of a very large, conspicuous mound was the council house, where important events were discussed and action taken. Every warrior, that is, every man who had taken the scalp of an enemy, was permitted to be heard around the council fire; but the talking was for the most part done by the privileged class of headmen, old men, wise men, and orators. The political organization of the Indians was weak. The villages were little democracies, where one warrior considered himself as good as another, except for the respect naturally due to the chiefs or headmen of the several clans, or to those who had the reputation of being wise and able. The sachem, or peace-chief, whose office was hereditary through connection with his mother's family, had but slight authority unless his natural gifts commanded respect.
