well-proportioned, their builders had not learned the use of the square or the plumb-line. The unit of measure was also apparently unknown, and even in the best types of ancient _pueblo_ masonry the joints of the stonework were not 'broken.' The Indian names for some of their structures, as _tipi, wigwam, wickiup, hogan_, have come into use to a great extent by English-speaking people."[12] [12] _Bulletin 30_, Bureau of American Ethnology.

By permission of the Bureau of American Ethnology] {50} Tribal Law and Custom There is but little exact data available respecting the social polity of the Red Race of North America. Kinship appears to have been the basis of government among most of the tribes, and descent was traced both through the male and female line, according to locality. In most tribes military and civil functions were carefully distinguished from each other, the civil government being lodged in the hands of chiefs of varying grades. These chiefs were elected by a tribal council, and were not by virtue of their office military leaders. Every village or group was represented in the general council by a head-man, who was sometimes chosen by the priests. Secret societies exercised a powerful sway. Hunting Hunting was almost the sole occupation of the males of the Indian tribes. So much were they dependent on the produce of the chase for their livelihood that they developed the pursuit of game into an art. In commerce they confined themselves to trading in skins and furs; but they disposed of these only when their personal or tribal requirements had been fully satisfied. When the tribe had returned from its summer hunting expedition, and after the spoils of the chase had been faithfully distributed among its members--a tribal custom which was rigorously adhered to--ceremonial rites were engaged in and certain sacred formulæ were observed. In hunting game the Indians usually erected pens or enclosures, into which the beasts were driven and slaughtered. Early writers believed that they fired the prairie grass and pressed in upon the panic-stricken herd; but this is contradicted by the Indians {51} themselves, who assert that fire would be injurious to the fur of the animals hunted. Indeed, such an act, causing a herd to scatter, was punishable by death. In exceptional cases, however, the practice might be resorted to in order to drive the animals into the woods. In pursuing their prey it was customary for the tribe to form a circle, and thus prevent escape. The most favourable months for hunting were June, July, and August, when the animals were fat and the fur of rich quality. To the hunter who had slain the animal the tribe awarded the skin and part of the carcass. The other portions were usually divided among the inhabitants of the village. As a result of this method of sharing there was very little waste. The flesh, which
