436 The American Naturalist. reed 
Extending out from the West branch of the Gila, about three 
_and one half miles above its confluence with the main Gila, is 
one of the most beautiful, wild and romantic canyons possible 
to be found. 
. The average width of this canyon is perhaps thirty-five or 
forty feet, while towering cliffs rise perpendicularly on either 
side to a height of from two hundred to three hundred feet K 
estimate. 
Through this wild glen there rushes, during the rainy sea- 
son, a small stream of pure water, clear as crystal. The lower — 
nearly one-half of these great cliffs is composed of a hard, 
dark colored basalt, upon which the elements have made but 
slight impression; and overlying them is a vast stratum of — 
buff colored conglomerate, such as occupies such extensive 
areas in southwestern New Mexico, portions of Arizona and 
California. 
Here the lower portion of this vast stratum of conglomerate 
has been worn away by the slow action of the elements, leav- 
ing a narrow projecting shelf of basalt extending along 
horizontally for some distance. i 
In the base of this conglomerate, nature has formed numer- — 
ous large connected caves. 
These caves the ancient Cliff-dwellers had taken possessi 
of, and in them reared their strange dwellings. 
Here may be seen upward of twenty-eight rooms, of di 
ent sizes, shapes and designs; which taken together form the 
most interesting group of these dwelling which the writer has 
ever seen. 
As the object of this paper is mainly to deal with the 
covery of the mummy already alluded to, a detailed descrip- 
tion of these and other Cliff-dwellings, ete., will be deferred to 
a future report.
