related and prohibited from intermarrying. The children usually followed the clan of the mother. The clans themselves were sometimes grouped into larger bodies of related kindred, to which the name of phratries has been applied. The clans were usually, but not always, named from animals, and each clan paid special reverence to its tutelary animal. Thus the Cherokee had seven clans, Wolf, Deer, Bird, Paint, and three others with names not readily translated. A Wolf man could not marry a Wolf woman, but might marry a Deer woman, or one of any of the other clans, and his children were of the Deer clan or other clan accordingly. In some tribes the name of the individual indicated the clan, as "Round Foot" in the wolf clan and "Crawler" in the Turtle clan. Certain functions of war, peace, or ceremonial were usually hereditary in special clans, and revenge for injuries with the tribe devolved upon the clan relatives of the person injured. The tribal council was made up of the hereditary or elected chiefs, and any alien taken into the tribe had to be specifically adopted into a family and clan. The clan system was by no means universal but is now known to have been limited to particular regions and seems to have been originally an artificial contrivance to protect land and other tribal descent. It was absent almost everywhere west of the Missouri, excepting in the South-West, and appears to have been unknown throughout the geater portion of British America, the interior of Alaska, and probably among the Eskimos. Among the plains tribes, the unit was the band, whose members camped together under their own chief, in an appointed place in the tribal camp circle, and were subject to no marriage prohibition, but usually married among themselves. p> With a few notable exceptions, there was very little idea of ​​tribal solidarity or supreme authority, and where a chief appears in history as tribal dictator, as in the case of Powhatan in Virginia, it was usually due to his own strong personality. The real authority was with the council as interpreters of ancient tribal customs. Even such well-known tribes as the Creeks and Cherokee were really only aggregations of closely cognate villages, each acting independently or in cooperation with the others as suited its immediate convenience. Even in the smaller and more compact tribes there was seldom any provision for coercing the individual to secure common action, but those of the same clan or band usually acted together. In this lack of solidarity is the secret of Indian military weakness. In no Indian war in the history of the United States has a single large tribe ever united in solid resistance, while on the other hand other tribes have always been found to join against the hostiles. Among the Natchez, Tinucua, and some other southern tribes, there is more indication of a central authority, resting probably with a dominant clan. p> The Iroquois of New York had progressed beyond any other...
