One of these disks or circular plates (figure 356) was found on the
head of a skeleton. The rim is rounded, and the opposite faces are
concave, with a perforation in the middle. Other forms of this worked
kaolin are spherical, oblong, or lamellar, sometimes more or less
decorated on the outer surface, as shown in plate CLXXII, _e_.
Another, shown in _f_, of the same plate, is cylindrical, and other
fragments of irregular shapes were found. A pigment made of micaceous
hematite was found in one of the Sikyatki paint jars. This material is
still used as coloring matter by the Tusayan Indians, by whom it is
called _yayala_, and is highly prized by the members of the warrior
societies.
