16 is small and apparently stationary, so that their neighbours will certainly absorb them, just as the Stuart Lake Carrier have long since absorbed the Sekani whom Harmon visited on Tachie river. Still a third process has operated among the Sekani in recent times, the amalgamation of separate bands into a single unit. The Yutuchan and T’sekani bands, that were often at feud during the first half of the nineteenth century, now occupy a single village at McLeod lake and have almost forgotten their old separation. Similarly the Tseloni and Sasuchan bands have combined at Fort Grahame. The prime causes of these amal- gamations were three: (1) closer contact at the trading posts; (2) the erection of permanent houses of wood around the trading posts instead of temporary lodges of brush or skin; and (8) the partial destruction of the bands through introduced diseases. Two at least of these causes, trading posts and diseases, are directly attributable to Europeans; but parallel forces, for example, destruction through war instead of disease, undoubtedly produced similar amalgamations long before any European made his appearance on the stage of Indian history. The history of the Sekani bands during the last two hundred years probably repeats, with modifications due to white influence, the history of other Athapaskan-speaking tribes that crossed the Rockies or descended from the north along the western flanks of the mountains many centuries earlier. This will appear still more probable when we examine the social organization and mythology of the present day Sekani, and perceive how they have tried to follow exactly the.same road as their Carrier and Tahltan neighbours.
