"For like reason we would make especial mention of the village of Wishram, at the head of the Long Narrows, as being a solitary instance of an aboriginal trading mart, or emporium. Here the salmon caught in the neighboring rapids were 'warehoused,' to await customers. Hither the tribes from the mouth of the Columbia repaired with the fish of the sea-coast, the roots, berries, and especially the wappatoo, gathered in the lower parts of the river, together with goods and trinkets obtained from the ships which casually visit the coast. Hither also the tribes from the Rocky Mountains brought down horses, bear-grass, quamash, and other commodities of the interior. The merchant fishermen at the falls acted as middlemen or factors, and passed the objects of traffic, as it were, cross-handed; trading away part of the wares received from the mountain tribes to those of the rivers and plains, and vice versa: their packages of pounded salmon entered largely into the system of barter, and being carried off in opposite directions, found their way to the savage hunting camps far in the interior, and to the casual white traders who touched upon the coast."
