a. Looking westward to Mounts
Dana and Gibbs from meadow at Farrington Ranch, southwest of Mono Lake;
photographed June 22, 1916. Meadow in foreground is in Transition Zone;
low hills beyond, interruptedly clothed with Jeffrey pine, are in
Canadian Zone; the forests, chiefly of lodgepole pine, on the slopes of
the peaks represent the Hudsonian Zone, and the upper bare portions of
the two mountains are in the Alpine-Arctic Zone. (This figure is
reversed, left to right; top.)
b. Side of Williams Butte facing northeast toward Mono Lake;
Transition Zone. Trees on the Butte are piñon pines, while in the
foreground are bushes of Kunzia and sagebrush, with a strip of
willows in the middle distance. Some birds characteristic of the
piño covered hill in September were Black-billed Magpie,
Woodhouse Jay, Piñon Jay, and Short-tailed Mountain Chickadee,
while in the sagebrush were Nevada Sage Sparrow, Brewer Sparrow,
Green-tailed Towhee, and Sage Thrasher. (bottom)

Common Shrews of the Yosemite region;
6/7 natural size. (left to right)
a. Navigator Shrew, east fork of Indian Cañon, June 23, 1915.
b. Yosemite Shrew, Yosemite Valley, December 29, 1914.
c. Dusky Shrew, same data as a.
The slender nose, inconspicuous eyes and ears, and plush-like pelage all
indicate relationship with the moles. The expanded, fringed hind toes
of the Navigator Shrew show correlation with its aquatic habits. For
discussion of species, see text, pp. 47, 50.
