rocks and upon the walls of cliff houses near the boundary line between 
Colorado and New Mexico. He says: 
The following were painted in red and black paints on the wall (apparently the 
natural rock wall) of a cliff house: At the head was a chief on his horse, armed with 
spear and lance and wearing a pointed hat and robe; behind this character were 
some twenty characters representing people en horses lassoing horses, ete. In fact

The best discussed and probably the most. interesting of the petro-

painted in red and white elay upon the smooth rocks. These were certainly done 
by the cliff-builders, and probably while the houses were in process of construction, 
since the material used is identical with the plaster of the houses. The sketches and
