meeting above were joined in
rectangles like those below, and the decoration was closed by a border
line at the top. The vessel was then completed in the light colored
material. In this ornament all forms are bounded by two classes of
lines, vertical and horizontal (or, viewed from above or below, radial
and encircling), the lines of the warp and the woof. Oblique bands of
color are made up of series of rectangles, giving stepped outlines.
Although these figures are purely geometric, it is not impossible that
in their position and grouping they preserve a trace of some imitative
conception modified to this shape by the forces of the art. They serve
quite as well, however, to illustrate simple mechanical elaboration as
if entirely free from suspicion of associated ideas.

In Fig. 321 I present a superb piece of work executed by the Indians
of the Tule River, California. It is woven in the closely impacted,
coiled style. The ornament is arranged in horizontal zones and
consists of a series of diamond shaped figures in white with red
centers and black frames set side by side. The processes of
substitution where changes of color are required are the same as in
the preceding case and the forms of figures and the disposition of
designs are the same, being governed by the same forces.

Another choice piece, from the Pima Indians of Arizona, is given in
Fig. 322. The lines of the ornament adhere exclusively to the
directions imposed by the warp and the woof, the stripes of black
color ascending with the turns of the fillet for a short distance,
then for a time following the horizontal ridges, and again ascending,
the complete result being a series of zigzag rays set very close
together. These rays take an oblique turn to the left, and the dark
figures at the angles, from the necessities of construction, form rows
at right angles to these. A few supplementary rays are added toward
the margin to fill out the widening spaces. Another striking example
of the domination of technique over design is illustrated in Fig. 323.
