Annual Reports of Academy of 
Bernardino Valley, which drains southward into the basin of the 
Rio Yaqui of Mexico and is separated from the San Simon Valley 
to the north by low hills. A portion of the ranch property is in 
Mexico, and its extensive areas of sacaton grass were very profitable 
collecting grounds. The rough surface of the nearby ‘‘bench,” 
with a covering of lava fragments, was of equal interest to us. 
From Douglas we moved eastward to our last collecting district 
at Hachita, New Mexico. From Hachita we made a short trip to 
the Hachita Grande Mountains, about thirty miles by the route 
followed. In Playas Valley at the west foot of the range, we 
found an area of black brush (Flourensia cernaa), which yielded 
important material, while a pull from this point of a thousand feet 
higher, to five thousand five hundred feet elevation, placed us in 
a broad canyon relatively close to the towering Hachita Peak 
itself. Mr. Hebard worked through the juniper and pinyon belt 
to a point above which sheer cliffs made the main peak inaccessible 
from the west side. The canyon floor and the nearby juniper 
and pinyon-clad slopes yielded many forms of interest. This same 
range had been examined a number of years ago by Dr. Pilsbry of 
the Academy, who, in his search for land mollusks, ascended the 
peak from the east. 
Leaving Hachita the evening of September 27, a brief stop to 
repack material was made at El Paso, and on the morning of 
October 1st, we reached Philadelphia, after a most profitable and 
interesting, as well as enjoyable, trip. 
THE ACADEMY’S DEPARTMENT OF BIRDS 
By Witmer Stone. 
The visitor to a large museum such as that of the Academy sees 
only the specimens which are displayed in the exhibition halls. 
Formerly all specimens were so displayed and persons unfamiliar 
with modern museum methods still have the idea that these ex¬ 
hibits include all of the museum’s collections. This, however, is 
by no means the case and the specimens on exhibition often con¬ 
stitute a comparatively insignificant portion of the museum’s 
resources.
