Note 219 — Chapter IV · —The Movements Of Peoples In Their Geographical Significance

The traditions of the Delaware Indians and Sioux in the north of the United States territory, and of the Creeks in the south, commence with each stock group as a united body, which, as it migrates, splits into tribes and sends out offshoots developing different dialects. Here was tribal differentiation after entry into the general stock area, the process going on during migration as well as after the tribes had become established in their respective habitats. Culture, however, made little progress till after they became sedentary and took up agriculture to supplement the chase.219 Tribes sometimes wander far beyond the limits of their stock, like the Iroquoian Cherokees of East Tennessee and North Carolina or the Athapascan Navajos and Apaches of arid New Mexico and Arizona, who had placed twenty or thirty degrees of latitude between themselves and their brethren in the basins of the Yukon and Mackenzie rivers. Such inevitably come into contrasted climatic conditions, which further modify the immigrants. [See map page 54.]
