being used as a dining hall. The water was conducted to a wooden
tank, where it was allowed to cool somewhat, and was thence piped
to a bathhouse. An analysis of the water, which is noticeably
sulphureted, follows:

The foregoing analysis contains a detailed report on substances
for which often no test is made. The primary alkaline character
of the water alkalinity due largely to weak acid radicles other than
the carbonate and the appearance as primary alkalinity of constit-
uents generally tabulated as tertiary alkalinity are of special interest.
The region is one of granitic rocks, and a fault that passes along
the east side of Warner Valley has been recognized by geologists
who have visited the locality. Warm springs of small flow issue
at several places in the valley west of the springs and suggest that
there is also leakage at these points from deep sources.
AGTTA CALIENTE SPRINGS (SAN DIEGO 9).
In the valley of Vallecito Creek, 35 miles southeast of Warner
Hot Springs, are small, unimproved warm springs known as Agua
Caliente Springs. These are near the extension of the fault through
Warner Valley, and possibly they issue along a continuation of this
line of structural weakness.
