THE ALKATCHO CARRIER OF BRITISH COLUMBIA 343 the Kwakiutl, who might be regarded as an aristocratic society, the Bella Coola were plutocratic. With the development of the White fur trade on the coast, and with an increasing demand for furs from the interior, the Alkatcho Carrier assumed new significance in Bella Coola economy. In the competition for new sources of wealth that characterized Northwest Coast economy a Carrier son- in-law gave a Bella Coola man a virtual trade monopoly, particu- larly in view of the Carrier concepts of bride-service. Thus the increasing importance of trade between the Bella Coola and the Alkatcho Carrier, as a result of the growing White fur trade on the coast of British Columbia at the end of the eight- eenth century, must have promoted intermarriage. The types of social relationships involved in marriage resulted inevitably in the integration of the potlatch-rank complex at Alkatcho. This process of trade, intermarriage, and acculturation was by no means a unique development in British Columbia, but, on the contrary, was characteristic of coast-interior relationships. The Bulkley River Carrier have intermarried with the Gitksan group of the T’simshian with whom they have always had friendly trade relations. The latter controlled the trade route down the Skeena River. They traded shells and copper with the Carrier for moose- hides and furs. Correlated with the trade and marriage relations between the Bulkley Carrier and the Gitksan are similarities of social organization and equation of phratries. The same thing happened with Sekani. To quote Jenness: When the Sekani were confined to the western side of the Rockies through the hostility of the Cree and the Beaver they impinged upon the Gitksan and Carrier. The Sekani not only fought, traded, and inter- married with them, but assimilated many of their customs, and tried to adopt their divisions into exogamous matrilineal phratries.12 The McLeod Lake band farthest from the Gitksan “abandoned the phratry system before it could be well established.” 1° The phratry system of the western divisions of the Tahltan were in- troduced by marriage with the Tlingit; but the Nelson River Indians well over to the east, out of the line of trade, never adopted phratries at all. Trade between the Tahltan and the Tlingit de- 12D. Jenness, The Sekani Indians of British Columbia (manuscripts). 13 [bid.
