them from the coast, not from tribes to the northeast (from whom they 
are at present separated by the Yakima-Klickitat), is hardly tenable, 
since the coast people who make coiled basketry are very irregularly 
distributed, and seem to have derived their ideas from the tribes liv- 
ing immediately east of them. Moreover, the chief trade routes and 
consequently the natural paths for the dissemination of culture in the 
interior lay mostly east and west, not north and south. 
Angular shapes belong to the northwestern part of the area. The 
square-mouthed type of the Wenatchi is different from the others, 
and resembles birch-bark baskets. 
There is a difference in the construction of basket rims made by the 
northern and southern Cascade tribes. Among the Klickitat, Cow- 
litz, and Nisqualli, as well as among the Wenatchi, the false braid rim 
is the usual finish. Such rims are seldom made by the Thompson, 
Lillooet, Chilcotin, and neighboring tribes, who prefer plain over-and- 
over stitching. Information on this point for the eastern Salish is 
lacking. The Columbia and Spokane used both varieties. 
Loopwork rims were made by all the Cascade people except the 
Chilcotin and coast tribes of British Columbia. They were found 
among the Lillooet, Thompson, Wenatchi, Columbia, and Klickitat 
east of the mountains, and the Cowlitz, Nisqualli, and Stalo to the 
west. They were also applied to twined baskets by the Snohomish 
and other coast tribes of Washington.
