e there is much freedom of expression, as the
artist carries the colored filaments back and forth or inserts new
ones at will. Still it will be seen that in doing this he is by no
means free; he must follow the straight and narrow pathway laid down
by the warp and woof, and, do what he may, he arrives at purely
geometric results.
[Illustration: FIG. 319. Base of coiled basket showing the method of
building by dual coiling. The base or warp coil is composed of
untwisted fiber and is formed by adding to the free end as the coiling
goes on. The woof or binding filament, as it is coiled, is caught into
the upper surface of the preceding turn--1/8.]

I will now present the examples, which for the sake of uniformity are
in all cases of the coiled ware. If a basket is made with no other
idea than that of use the surface is apt to be pretty uniform in
color, the natural color of the woof fillets. If decoration is desired
a colored fillet is introduced, which, for the time, takes the place
and does the duty of the ordinary strand. Fig. 319 serves to show the
construction and surface appearance of the base of a coil made vessel
still quite free from any color decoration. Now, if it is desired to
begin a design, the plain wrapping thread is dropped and a colored
fillet is inserted and the coiling continues. Carried once around the
vessel we have an encircling line of dark color corresponding to the
lower line of the ornament seen in Fig. 320. If the artist is content
with a single line of color he sets the end of the dark thread and
takes up the light colored one previously dropped and continues the
coiling. If further elaboration is desired it is easily accomplished.
In the example given the workman has taken up the dark fillet again
and carried it a few times around the next turn of the warp coil; then
it has been dropped and the white thread taken up, and again, in turn,
another dark thread has been introduced and coiled for a few turns,
and so on until four encircling rows of dark, alternating rectangles
have been produced. Desiring to introduce a meandered design he has
taken the upper series of rectangles as bases and adding colored
filaments at the proper time has carried oblique lines, one to the
right and the other to the left, across the six succeeding ridges of
the warp coil. The pairs of stepped lines
