THE ALKATCHO CARRIER OF BRITISH COLUMBIA 337 nature of contact with the Coast cultures and the bearing of that contact upon Alkatcho Carrier Culture. Offhand, in view of the continuous and direct contact between the Carrier and the Bella Coola of the Coast and the general re- semblance between the formal structure of the potlatch-rank com- plex in both cultures, the source of the Carrier potlatch-rank complex might be definitely attributed to Bella Coola. But before accepting this premise it is necessary to dispose of two other possi- bilities. The potlatching complex might have been derived di- rectly from the Tsimshian, with whom the Carrier have had some contact, or indirectly from the Tsimshian by way of the Upper Carrier at Hazelton, with whom contact was intermittent though not infrequent, even some intermarriage having taken place. The former possibility is improbable simply on the basis of meagreness of contact. The latter possibility, though, must be considered with some seriousness, particularly since the Alkatcho Carrier use of crests can be derived, as will be seen later, from the clan and phratry system of the Upper Carrier, which in turn had been drawn from the Tsimshian. But an analysis of the historical factors re- sponsible for the particular integration of crest prerogatives at Alkatcho is the very key to the source of the potlatch-rank complex in that culture. This problem has already been considered in some detail.?7 A summary will suffice. An analysis of one of the social units among the Alkatcho Car- rier, referred to by the natives as a nEts/, or crest group, is puzzling because of the contradictory information given by the Indians. On the one hand the crest group is described as a local group having economic and ceremonial functions in common, and own- ing the prerogative of displaying the crest animal as a carving on grave posts, house ridge-poles, paintings on house fronts, and on such various other objects as spoons, clothing, etc. Each nEtsi has its own songs and dances. None of the crest groups had a legend relating to its origin. It appears that since the ownership and dis- play of a crest must be validated by a distribution of property, membership can be accessible only to the nobility—in Alkatcho Carrier terms, anyone who can potlatch. On the other hand, a genealogical study of crests reveals that a nEtsi has no marriage 71. Goldman, op. cit.
