degree of finish by the crumbling and abrading 
processes. 
Although the sculptural tools were largely of stone, 
the range of process was identical with that of the 
Greeks and Romans. Sculpture of the greatest periods, 
the range of articles made, and the subjects treated 
?/ere hardly less extensive. Sculpture in relief and 
in the round came into use side by side, the two 
methods grading one into the other, while intaglio work 
was confined largely to pictographs and glyphic in¬ 
scriptions . 
In reviewing the sculptural work of the aborigines 
we can not pass over the carvings in'wood, many of which 
deserve high praise but this branch may be reserved for 
subsequent treatment. 
There is little in stone requiring attention north 
of the Valley of Mexico.
