Jet, Lignite, Anthracite, Cannel coal. Car- 
bonaceous materials used to some extent 
by Indians. Jet of excellent quality oc- 
curs in Colorado, and the Indians of the 
arid region employ it for jewelry and 
various carvings. Good examples of lig- 
nite ornaments were obtained by Fewkes 
from the ancient ruins of Arizona, and of 
jet by Pepper from the ruins of Chaco 
canyon, N. Mex. Among the latter is a 
well-sculptured frog decorated with inlaid 
designs in turquoise and shell. Cannel- 
coal objects are found in the Ohio valley 
mounds, but few specimens carved from 
anthracite are known. _ A small, well- 
carved human head of jet-like stone was 
obtained by Smith from a shell heap on 
lower Frazer r., Brit. Col., and Niblack 
says that the N. W. coast tribes pulverize 
lignite and mix it with oil for paint.
