MINOR PERENNIAL SPRINGS. 835

MUD SPRING (TEHAMA 6).
A few small springs form watering places near the western base of
the Sierra, on the slopes of tuffaceous lava that border Sacramento
Valley in eastern Tehama County. Mud Spring rises in a rock-walled
pool, 6 feet in diameter, at the northern edge of the county road, 13
miles north of east from Red Bluff. Its water has been piped 200
yards westward to a watering trough near sheepmen's corrals and
camp, where the measured flow was about one-half gallon a minute.
GEARY SPRING (TEHAMA 7).
Geary Spring is similar to Mud Spring in character. It is about
7 miles farther south at the side of a small drainage channel in the
gentle, plateau-like slope. The water rises 50 yards south of a wagon
road, in a rock-curbed pool, 3 feet in diameter, that is used as a water-
ing and camping place by travelers and stockmen.
The water of Geary and Mud springs is of good quality, and their
observed temperatures, which were respectively 66° and 62°, suggest
that it rises from a depth of several hundred feet, probably from a
layer in the bedded volcanic tuffs.

HENDERSON SPRING (BTTTTE 1).
Henderson Spring issues from a steep bank of slate, in the bottom
of the canyon of Big Butte Creek, 11 miles by road and trail, north
of Stirling City. The water is said to have medicinal properties and
has been used for a number of years by several residents of the region,
but in the fall of 1909 no mineralization was noticeable to the taste.
At this time, however, the water was diluted by storm water. The
spring is not easy of access, as the canyon is steep and only a dim
trail leads from prospectors' cabins on its upper slopes down to the
creek and the spring.
BLACK SPRING (MARIPOSA 1).
In Yosemite Valley there are several perennial springs of cold
water, of which Black Spring is perhaps the best known. It issues
on the slopes on the northern side of the stage road, 4f miles south-
west of Yosemite post office, and is piped to the roadside, where it
forms a watering place for horses as well as people. The water is
cold and of excellent quality.
MOSS SPRING (MARIPOSA 3).
Moss Spring issues on the southern side of Yosemite Valley, about
one-third of a mile south of Black Spring, in the lower land at the
base of the valley wall. It is similar in character to Black Spring,
but as it is not beside a main road its water has been little used.
