ARTESIAN SPRINGS. 323

BLIND SPRING (MONO 13).
Blind Spring, which is situated about 3 miles east of south from
Benton, was formerly of some importance as a watering place, but
of late years its flow, always slight, is reported to have nearly ceased.
It is in open valley land and is said to have received its name because
there was little growth near it to indicate the presence of water.
ARTESIAN SPRING NEAR HOPLAND (MENDOCINO 30).
A spring which is apparently of artesian origin issues on the Horst
ranch, 1 mile north of Hopland. The water rises in a grove of willows
at the mouth of a small ravine on the western edge of valley land
along Russian River. The spring is protected by a board curbing,
which forms a shallow pool 8 by 10 feet across, and the discharge
about 5 gallons a minute of faintly sulphureted wate.r is used to
irrigate a vegetable garden.
The adjacent hills are composed of the older sandstones and shales
that form so large a portion of the Coast Ranges. Their structure,
however, is not favorable to the occurrence of water under artesian
pressure, and the spring is probably supplied by alluvial water that
rises at this place. At the time of the earthquake of April 18, 1906,
the spring ceased flowing for a short time but gradually returned to
its normal discharge.
ARTESIAN SPRINGS IN SHASTA VALLEY (SISKIYOU 13).
A number of springs which rise in the northeastern part of the
State are probably of alluvial artesian origin. Two of these that
yield considerable water rise in Shasta Valley at points about 10
and 11 miles southeast of Montague, one being known as Big Spring
and the other as Little Spring. The former yields a large flow of
water that is noticeably above the normal temperature; the latter, a
mile farther south, yields a smaller flow of similar character. Both
springs are used to irrigate tracts of meadowland but are capable of
much more extensive development.

ARTESIAN SPRING NEAR ALTURAS (MODOC 9).
At the southern base of a low but extensive mound in meadow-
land 1J miles southeast of Alturas is a spring of small flow at which
a hydraulic ram has been installed that pumps the water to troughs
in a corral on the mound. The observed discharge from the spring
was only about 1 gallon a minute, but there was much seepage near
it. The temperature of the water (72°) indicates that it is of deep-
seated origin rather than of essentially surface flow. It may rise
from rock beds that underlie the valley alluvium and be similar in
origin to the warm springs near Rattlesnake Creek (Modoc 8) and near
