Note 245 — Chapter V · —Geographical Location

An even closer connection exists between adjoining peoples who are united by ties of blood and are further made economically dependent upon one another, because of a contrast in the physical conditions and, therefore, in the products of their respective territories. Numerous coast and inland tribes, pastoral and agricultural tribes are united because they are mutually necessary. In British Columbia and Alaska the fishing Indians of the seaboard long held a definite commercial relation to the hunting tribes of the interior, selling them the products and wares of the coast, while monopolizing their market for the inland furs. Such was the position of the Ugalentz tribe of Tlingits near the mouth of the Copper River in relation to the up-stream Athapascans; of the Kinik tribe at the head of Cook's Inlet in relation to the inland Atnas,245 of the Chilcats of Chilkoot Inlet to the mountain Tinnehs. Similarly, the hunting folk of the Kalahari Desert in South Africa attach themselves to influential tribesmen of the adjacent Bechuana grasslands, in order to exchange the skins of the desert animals for spears, knives, and tobacco.246 Fertile agricultural lands adjoining pastoral regions of deserts and steppes have in all times drawn to their border markets the mounted plainsmen, bringing the products of their herds to exchange for grain; and in all times the abundance of their green fields has tempted their ill-fed neighbors to conquest, so that the economic bond becomes a preliminary to a political bond and an ethnic amalgamation growing out of this strong vicinal location. The forest lands of Great Russia supplement the grain-bearing Black Lands of Little Russia; the two are united through geographico-economic conditions, which would not permit an independent existence to the smaller, weaker section of the south, ever open to hostile invasion from Asia.247
