their points they form the fish-backbone pattern as it is sometimes 
made around Spuzzum. This is a fairly common design in general 
art but appears very rarely on baskets (sketch 150). Chevrons, in 
concentric formation (shown in sketch 151), turned sidewise or up- 
ward, are called butterflies or butterfly wings. There is a peculiar 
arrangement of chevrons that may be described as “slipped past’ 
(sketch 152). This is given a great variety of names, such as broken 
back, bent leg, fishhook, hook, hooked end, cross, head, and root- 
digger. The last three are undoubtedly bestowed because of the 
recognition of the T form, which is treated under the section imme- 
diately following dealing with the right angle with one long side. 
The derivation of this figure is doubtful. It is an excellent represen- 
tation of the braided rim as it appears on some baskets and it is very 
odd that it does not seem to have been so considered. Possibly this

has been due to the fact that braided rims are not common except 
among the Klickitat, and to the circumstance that the women who 
were familiar with such rims may not have been consulted as to the 
meaning of the pattern. Broad chevrons divided lengthwise are 
usually called bent back, leg, or middle, although the names rainbow 
half or striped snake are sometimes applied (sketches 158, 154). 
The right angle with one long side.—The right angle; and occasion- 
ally the obtuse angle, with one long side, is almost universally known 
as the leg or foot design, although in serial or all-over arrangement 
it sometimes becomes bent back, caterpillar, grasshopper, or hook. 
Very little distinction seems to be made between the simple right 
angle and the Z figure, except that the former is more often termed 
foot, and the latter bent knee or leg (sketches 155 to 163). The 
result of the junction of the two Z figures gives the beginning of the 
meander as seen in sketches 167 and 168, although for these no 
interpretation has been noted. Standing upright they are probably
