348 ACCULTURATION IN SEVEN AMERICAN INDIAN TRIBES the pretext of an insult “threw property into the fire” by giving his rival some blankets or other commodity which was not to be returned. This formalized the disruption of the rivalry. The rival was temporarily shamed; but at a later date the two might have resumed the rivalry at scratch. The mechanism could hardly have been abused because the recipient of the “thrown into the fire” property, though losing face for the moment, acquired new wealth which he could utilize at another potlatch. As elsewhere on the Northwest Coast, Carrier potlatching was never an individual enterprise. The Carrier potlatch necessarily had to entail the collective effort of the extended family—the eroup of siblings, their wives, children, and children’s wives. At the head of this unit was the oldest of the sibling group, who when not a noble was called detsa “first one.” In pre-Coast days, when Carrier social organization approximated that of the Northern Athabascans, the detsa was probably the equivalent of a band leader who regulated hunting somewhat, but whose authority was not strong enough to prevent the constant fragmentation of the band. Under the conditions of potlatching and the drive for build- ing social prestige, the extended family became a more cohesive unit. Leadership was strengthened. The sanctions supporting the authority of a chief, who had a fixed rank as a noble and who necessarily had to serve as the spear-head for the collective pot- latch, were more concretely developed. In addition, a new sanc- tion revolving around social status—fear of being shamed through the non-performance of the formal obligations attendant upon the maintenance of rank—acted as an effective force in strengthening group unity. The chief could determine his successor, and was instrumental in elevating one of the family-line-descendants to nobility. Group cohesiveness, however, never developed effectively be- yond the extended family. It is probable that in earlier days, as elsewhere on the Coast, village and extended family were synony- mous. But where a number of family lines inhabited the same village, village solidarity was expressed in two ways; a common front was presented against invaders of village hunting territory, and the most important noble of the group was recognized as the potlatch chief for the entire village. He built the central potlatch
