A PRELIMINARY SKETCH 1 BY W.J. McGEE Out of some sixty aboriginal stocks or families found in North America above the Tropic of Cancer, about five-sixths were confined to the tenth of the territory bordering Pacific ocean; the remaining nine-tenths of the land was occupied by a few strong stocks, comprising the Algonquian, Athapascan, Iroquoian, Shoshonean, Siouan, and others of more limited extent. The Indians of the Siouan stock occupied the central portion of the continent. They were preemine

In colloquial usage and in the usage of the ephemeral press, the term "Sioux" was applied sometimes to one but oftener to several of the allied tribes embraced in the first of the principal groups of which the stock is composed, i.e., the group or confederacy styling themselves Dakota. Sometimes the term was employed in its simple form, but as explorers and pioneers gained an inkling of the organization of the group, it was often compounded with the tribal name as "Santee-Sioux," "Yanktonnai-Sio

The demotic organization of the Siouan peoples, so far as known, is set forth in considerable detail in Mr Dorsey's treatises 52 and in the foregoing enumeration of tribes, confederacies, and other linguistic groups. Like the other aborigines north of Mexico, the Siouan Indians were organized on the basis of kinship, and were thus in the stage of tribal society. All of the best-known tribes had reached that plane in organization characterized by descent in the male line, though many vestiges and

The institutional connection between the Siouan tribes of the plains and those of the Atlantic slope and the Gulf coast is completely lost, and it is doubtful whether the several branches have ever been united in a single confederation (or "nation," in the language of the pioneers), at least since the division in the Appalachian region perhaps five or ten centuries ago. Since this division the tribes have separated widely, and some of the bloodiest wars of the region in the historic period have

According to tribal traditions collected by Dorsey, the ancestors of the Omaha, Ponka, Elwapa, Osage, and Kansa were originally one people dwelling on Ohio and Wabash rivers, but gradually working westward. The first separation took place at the mouth of the Ohio, when those who went down the Mississippi became the Kwapa or Downstream People, while those who ascended the great river became the Omaha or Up-stream People. This separation must have occurred at least as early as 1500, since it prece

The second postulate, which may be regarded as a corollary of the first, is that the primary conjugal condition was one of promiscuity, out of which different forms ot marriage were successively segregated. Now the wide range in institutional development exemplified by the American Indians affords unprecedented opportunities for testing this postulate also. The simplest demotic unit found among the aborigines is the clan or mother-descent group, in which the normal conjugal relation is essential
