BOAS] SUMMARY AND CONCLUSION Ste 
their varied surface treatment by means of alternations in color. 
Considering the great variety of patterns produced by the Thomp- 
son, it is a surprising fact that so few relationships between their art 
and the typical work of the other centers where imbrication is de- 
veloped are evident. We have seen that the Klickitat, who possess 
typical Californian designs, execute them most conspicuously in the 
Salish technique, but the Salish have not adopted any of the Klickitat 
styles, although their twined bags resemble those of the Klickitat 
which are ornamented with Plains designs. We have seen that the 
Lillooet, who with the Thompson may be considered as the chief 
exponents of imbrication, have many ideas of decoration in common 
with the Tlingit. They execute false embroidery patterns in imbri- 
cation, and they have even to a very limited extent attempted to 
make false embroidery themselves. Again, Skeena River (?) designs 
in overlay are found elsewhere in several other types of technique. 
The Thompson and Lillooet possess many patterns in common. 
Some of these are presumably of Lillooet origin, but they are not the 
same as those common to the Lillooet and Tlingit. The Chilcotin 
and Tlingit also use patterns which are more or less alike, although, 
as in the case of the Lillooet and Tlingit, executed in different 
styles of technique. 
While the Chilcotin and Thompson employ some similar decorative 
devices the Thompson use practically no designs which the Chilcotin 
seem to have in common with the typical Tlingit patterns, nor yet 
those styles which the Chilcotin have developed and which are 
characteristic of them. 
The lesser Salishan tribes making imbricated baskets, of whom it 
will be remembered there are a great number, probably have many 
designs in common with the Thompson which were no doubt devel- 
oped in the region and many purely local features are common to the 
Lillooet and Thompson. Outside of this, in most respects, the 
Thompson seem to have occupied the place of the eddy in the whirl- 
pool of travel and intercourse, and to have erected their art on the 
foundation of old Plains designs. Now and then a stray pattern 
from some region on the outside has come in, such as the “leg” 
design, which while very popular in both Salish and California 
regions has received entirely different treatment at the hands of the 
two sets of artists. 
Among themselves the Thompson have developed their art to an 
astonishing degree. All the styles of arrangement which prevail 
elsewhere are found here also, but it would seem that this fact must 
be ascribed to the ingenuity and inventiveness of the people them- 
selves rather than to borrowed ideas, since the design elements which 
would naturally accompany a typical arrangement from another 
tribe would scarcely fail to appear at least occasionally if borrowing
