British Columbia, especially the Haidas of the Queen Charlotte Islands. The most important features of their environment were the submerged coast with its easy navigation, the mild oceanic climate, and the dense pine forests. The Haidas, like the Iroquois, appear to have been a people who were still advancing. Such as it was, their greatness was apparently the product of their own ingenuity and not, like that of the Mexicans, an inheritance from a greater past. The Haidas lacked the relentless energy of the Iroquois and shared the comparatively gentle character which prevailed among all the Indians along the Pacific Coast. They were by no means weaklings, however. Commercially, for instance, they seem to have been more advanced than any North American tribe except those in the Mexican area. In architecture they stood equally high. We are prone to think of the Mexicans as the best architects among the aborigines, but when the white man came even the Aztecs were merely imitating the work of their predecessors. The Haidas, on the contrary, were showing real originality. They had no stone with which to build, for their country is so densely forested that stone is rarely visible. They were remarkably skillful, however, in hewing great beams from the forest. With these they constructed houses whose carved totem poles and graceful facades gave promise of an architecture of great beauty. Taking into account the difficulties presented by a material which was not durable and by tools which were nothing but bits of stone, we must regard their totem poles and mural decorations as real contributions to primitive architecture. In addition to these three highest types of the red man there were many others. Each, as we shall see, owed its peculiarities largely to the physical surroundings in which it lived. Of course different tribes possessed different degrees of innate ability, but the chief differences in their habits and mode of life arose from the topography, the climate, the plants, and the animals which formed the geographical setting of their homes.
