segmentation is the striking characteristic of their condition. Each tribe was individualized by a name, by a separate dialect, by a supreme government, and by the possession of a territory which it occupied and defended as its own. The tribes were as numerous as the dialects, for separation did not become complete until dialectical variation had commenced. Indian tribes, therefore, are natural growths through the separation of the same people in the area of their occupation, followed by divergence of speech, segmentation, and independence.
The exclusive possession of a dialect and of a territory has led to the application of the term nation to many Indian tribes, notwithstanding the fewness of the people in each. Tribe and nation, however, are not strict equivalents. A nation does not arise, under gentile institutions, until the tribes united under the same government have coalesced into one people, as the four Athenian tribes coalesced in Attica, three Dorian tribes at Sparta, and three Latin and Sabine tribes at Rome. Federation requires independent tribes in separate territorial areas; but coalescence unites them by a higher process in the same area, although the tendency to local separation by gentes and by tribes would continue. The confederacy is the nearest analogue of the nation, but not strictly equivalent. Where the gentile organization exists, the organic series gives all the terms which are needed for a correct description.
An Indian tribe is composed of several gentes, developed from two or more, all the members of which are intermingled by marriage, and all of whom speak the same dialect. To a stranger the tribe is visible, and not the gens. The instances are extremely rare, among the American aborigines, in which the tribe embraced peoples speaking different dialects. When such cases are found it has resulted from the union of a weaker with a stronger tribe speaking a closely related dialect, as the union of the Missouris with the Otoes after the overthrow of the former. The fact that the great body of the aborigines were found in independent tribes illustrates the slow and difficult growth of the idea of government under gentile institutions. A small portion only had attained to the ultimate stage known among them, that of a confederacy of tribes speaking dialects of the same
