The patterns used on these baskets consist of angular forms, except on modern placques, and bear names.[116] From the way in which these are used we may infer that they have no symbolic significance. I give here a selection of these. Fig. 304 _a_, _b_, _c_, patterns consisting of zig-zag lines, represent in this order: the woodworm or the woodworm tracks (_a_), lightning (_b_), the butterfly (_c_). The rectangle divided by an oblique line, (_d_), represents tracks of the bear; the dark part of the rectangle may be interpreted as the sole of the foot; the light part of the rectangle as the claws. The design (_e_) is called the arrow; (_f_) the rainbow; (_g_) fire weed; and (_h_) the hood of the raven. Fig. 305 _a_ shows various representations of the isosceles triangle, some of which are identical with the forms occurring in California. All of these are called head of the salmon-berry. The designs _b_, _c_, and _d_, are closely related; (_b_) is generally used on the narrow central band which separates two broad design bands; it is called “tying”. Flying geese are represented in (_c_); tracks of geese in (_d_). The complicated design in (_e_) is called “raven tail”; the relation between this name and the form is not clear; (_f_) shows a number of representations of the wave. Designs (_g_) and (_h_) are from circular placques; (_g_) represents the fern frond; (_h_) the porpoise. In the last named case the relation between form and name is obscure. [116] G. T.

I have little doubt that the designs are closely related to the blanket patterns previously referred to and to the porcupine quill embroidery of the tribes of the interior. The design fig. 304 _h_, for instance, is found in identical form on the lowest stripe of the Bella Coola blanket on top of Plate XII. The arrangement of patterns in blocks on these blankets is also similar to the arrangement found in this type of basketry. In fact the technique is a kind of embroidery in which the decorative material is wrapped around the woof strand when the basket is being made. The materials used are grasses and fern stems of contrasting color. [Illustration: Fig. 305. Decorative designs from Tlingit basketry.]
