189. Textile Clothing
Clothing in general is too much an adaptation to climate to render satisfactory its consideration wholly by the method here followed. But clothing of textiles shows a distribution that is culturally significant. The distribution is that of loom-woven cotton; the salient characteristic is rectangular shape: the blanket shawl, the poncho, the square shirt and skirt. In the Northwest Coast region hand and half-loom woven capes and skirts of bast were worn more or less. But these were flaring—trapezoidal, not rectangular—and thus evidently represent a separate development.
In all the cloth weaving areas, and in them only, sandals were worn. The spatial correlation is so close that there must be a connection. It may be suggested that the sandal originated, or at least owed its spread, to textile progress. Again the Northwest Coast corroborates by being unique; it is essentially a barefoot area.
To summarize. The original textile arts of the race were probably first advanced to the stages intermediate between basket and cloth making in Middle America. Thence they spread north and south, but not quite to the limits of the hemisphere, being retained in special usage chiefly in the Northwest. With the cultivation of cotton in Middle America, spinning and the loom came into use, and were ultimately carried to the Southwest, but not beyond. Cloth garments and sandals promptly followed. The heddle was evidently devised last, and did not diffuse beyond Middle America.
