166 Mackenzie’s Voyages laid ourselves down to rest, but I never enjoyed a more sound and refreshing rest, though I had a board for my bed and a billet for my pillow.” A dam across the river built with great labour and con- siderable ingenuity, below which a series of salmon-traps were placed, enabled the natives to obtain large supplies of salmon annually with the least possible exertion. It was owned exclusively by the chief, who portioned out the catch as he saw fit among the tribesmen. Here was evidence of an aristocracy of wealth, and of capitalism in its primitive form.
