We cannot doubt that if the Indian had succeeded in domesticating the buffalo before the advent of the white man, it would have formed the most general unit in use, as we shall find its congeners being employed in all parts of the old world.

With the Haidas it is still sometimes worn as an ornament though it has disappeared as a medium of exchange. The blanket of the trader has now however supplanted the skin as the principal unit.
