as “big’’ or “morning” stars. It seems as if the outlined form 
(sketch 218) has been derived from 217. Thus simply presented it 
is known as “‘star,’’ but the elaborated figure shown in sketch 219 
is called “‘leaf’’ in the neighborhood of Spuzzum. Sketches 220 and 
221 are forms of crosses, but the pronounced center at the intersec- 
tion of the lines and the radiating effect produced by the supple- 
mentary treatment are responsible for their interpretation as repre- 
sentations of the sun. They are quite unusual and are not seen 
except on circular lids, but they are often painted on pieces of skin. 
TRIANGLES 
All triangular forms, regardless of the type, are known over the 
entire region as arrowheads. They may be plain or subdivided into 
colored sections, and occur singly or in combination with other 
figures. Although this is the general name in the application of which 
one could hardly err much, others ‘are often bestowed on designs in 
which the triangles are subdivided in a peculiar fashion or where

their combination is sufficiently striking to suggest a different con- 
notation. The fact that the triangle is called arrowhead over 
practically the whole extent of North America may be due to the 
circumstance that in the world of natural or artificial objects as they 
appear to the Indian triangular forms are comparatively rare. The 
arrowhead is an implement of almost world-wide distribution. Its 
age and its important position in the material culture of the people 
would be sufficient to connect it with the geometric figure which 
offers such a striking resemblance to it and to account for the adoption 
by the Thompson of its name. 
Among the most common secondary names referring to natural or 
artificial objects, insects, plants, etc., are ‘‘wing” (either that of a 
bird or that of an insect, especially the butterfly wing), mountains, 
clouds, leaves, teeth, snares, and beads. A name which owes its 
existence solely to the vertical, diagonal, or more rare horizontal 
arrangement of triangles, or to the diagonal alignment of squares 
by which figures with stepped or serrated outlines may be secured, is 
ladder. In this case the element is of no importance except as it 
lends the stepped outline to the whole design. There are a few
