344 ACCULTURATION IN SEVEN AMERICAN INDIAN TRIBES veloped only after the establishment of trading-posts by the Rus- sians. The Tlingit became the middlemen for trade between the Indians of the interior and the White fur traders. The Tahltan traded almost exclusively with the Tlingit and with the Kaska.™* Bella Coola-Carrier intermarriages were not very common, and for good reasons. Not only did the Bella Coola endogamic tend- encies restrict such alliances, but the economic strain upon any Carrier family entering into a series of affinal potlatch exchanges and the necessity of participating in the rivalrous potlatches more or less upon Bella Coola terms was more than most Carrier families could sustain. Therefore, only a few Carrier individuals, the suc- cessful hunters, the shrewd and energetic traders, the lucky gam- blers, were able to acquire enough wealth to participate upon a basis of relative equality in Bella Coola potlatches. These indi- viduals, having acquired “big names” from the coast, apparently formed the first Carrier aristocracy. Unfortunately, detailed accounts of marriages and the conse- quences therefrom are lacking both from the Carrier and the Bella Coola data. But a knowledge of marriage practices of these groups makes possible at least a hypothetical reconstruction of the inter- marriage process. For the Bella Coola no marriage was socially sanctioned unless it had been validated by a series of property ex- changes. At the engagement “‘secret gifts” were given to the bride’s parents. Then food and presents were distributed by the family of the groom to the village of the bride. To “open the door” for the bride, the groom’s family and friends were required to give pres- ents to the bride’s family and to perform a number of menial tasks for them. At the wedding ceremony, after a recitation of the fam- ily myths, a name from the lineage of the bride was bestowed upon the groom, to be used by his children. Subsequently, relations be- tween the two families were further cemented by mutual assistance in ceremonies. At intervals after the marriage the bride’s family made payments to the groom to “repurchase” the woman, the lat- ter rising in social status with each “repurchase.” It is obvious how, once such a marriage had been consummated, the Carrier family would be completely enmeshed in the total fabric of Bella Coola culture. In fact, one individual at present at Alkatcho whose 14 James Teit. Incomplete manuscripts on Tahltan.
