Thompson than among the Lillooet, where, however, they are not 
lacking. Plate 32, b, pictures an all-over distribution in the upper 
field adapted to the typical Lillooet style. In present-day Thompson 
baskets these patterns are not often seen. 
Large single patterns are not very numerous. They are probably 
all of modern conception. The pattern shown on Plate 33, 6, was 
introduced by an Uta’mqt woman, who called it “leaves and ferns.” 
It is obviously derived from the hammer pattern, although so differ- 
ently interpreted. Plate 28, f, shows a variation of the widely known 
“leg’’ design; Plate 28, g, what was interpreted as part of an arrow 
design; Plate 33, d, merely part of a design, the remainder of which 
is probably carried over to the other side of the basket. More data 
about these patterns would be very desirable; for instance, whether 
they were taken from other articles, such as blankets. Surely the 
last pattern suggests ‘‘borrowing,’’ since it is placed in a manner 
foreign to the usual basket arrangements and is too large for proper 
presentation to the eye at one glance. 
For several reasons it would seem that the large rectilinear designs 
are of foreign extraction. In the first place the upper half of the 
surface which bears these designs has an imbricated background, a 
trait which, except for the few definite patterns always appearing with 
this style, is seen only in a few very modern specimens which differ 
from the older art in design, material, shape, color, and general 
treatment. 
Secondly, the patterns used in this type of decoration number 
about six or eight only. They are large. Generally Thompson 
designs are small, or if they assume any considerable size they are 
cut up by checkerwork or some other form of subdivision, which 
does away entirely with any considerable plain surface inclosed in 
outlines. Thirdly, these designs are all rectangular. Thompson 
designs as a whole show fewer rectangles than any other figures, and 
when these do appear they are small. The large outlined square, 
or anything approaching it excepting for these few designs, all of 
similar type, is conspicuously absent. Fourthly, these same six or 
eight patterns are typically Lillooet. 
The early type of simple Thompson baskets, characterized by 
the undivided field and unimbricated background, is still produced 
in large numbers and has always been one of the commonest styles in 
use. The division of the field is made according to Lillooet standards, 
with designs worked partly or wholly on unimbricated backgrounds. 
It seems likely, therefore, that the fashion of so dividing the surface 
into fields came into vogue at a later time. With these, as part of the 
complex, came the peculiar designs always associated by the Thomp- 
son with this style, the so-called head, mouth, hammer, intestine, 
grave-box, and similar patterns. Any of these alone fills the entire 
upper or lower field, and is, according to the particular design, either
