esent the same idea, and that a mythologic bird was
intended in each instance.

The step in conventionalism from the last-mentioned figure of a bird
to the next (plate CXLVII, _a_) is even greater than in the former.
The head in this picture is square or rectangular, and the wings
likewise simple, ending in three incurved triangles without
appendages. The tail has five feathers instead of three, in which,
however, the same symbolic markings which distinguish tail-feathers
are indicated.

The conventionalized wings of this figure are repeated again and again
in ancient Tusayan pottery decorations, as one may see by an
examination of the various birds shown in the plates. In many
instances, however, all the other parts of the bird are lost and
nothing but the triangular feathers remain; but as these have the same
form, whatever organs are missing, the presumption is that their
meaning has not changed.

In passing to the figure of the bird shown in plate CXXXVIII, _b_, we
find features homologous with those already considered, but also
detect considerable modification. The head is elongated, tipped with
three parallel lines, but decorated with markings similar to those of
the preceding figure. The outstretched wings have a crescentic form,
on the anterior horn of which are round spots with parallel lines
arising from them. This is a favorite figure in pottery decoration,
and is found very abundantly on the exterior of food bowls; it
represents highly conventionalized feathers, and should be so
interpreted wherever found. The figure of the body of the bird
depicted is simple, and the tail is continued into three
tail-feathers, as is ordinarily the case in highly conventionalized
bird figures.

The most instructive of all the appendages to the body are the
club-shape bodies, one on each side, rising from the point of union of
the wings and the breast. These are spatulate in form, with a terraced
terminal marking. They, like other appendages, represent feathers, but
that peculiar kind which is found under the wing is called the breath
feather.[144] This feather is still used in certain ceremonials, and
is tied to certain prayer offerings. Its ancient symbolism is very
clearly indicated in this picture, and is markedly different from that
of either the wing or tail feathers, which have a totally different
ceremonial use at the present time.

For convenience of comparison, a number of pictures which undoubtedly
refer to
