82 SPRINGS OF CALIFORNIA.

The analyses indicate that the water is preeminently primary
alkaline in character, resembling a solution of ordinary baking soda
through which carbon dioxide has been passed. The presence of
barium, strontium, lithium, and iodine, the excess of magnesium over
calcium, and the relatively large proportion of. borates are of interest.
The apparent lack of agreement in the tertiary alkalinity of the two
analyses is accounted for by the omission of the carbon dioxide deter-
mination in Hilgard's analysis.
In 1909 water from the lowest spring was piped to baths, that from
the central spring was piped across the creek to the laundry, and that
from the upper spring rose in a cemented drinking basin. The
observed temperatures were, respectively, 120°, 122°, and 135°, and
estimated flows about 7, 5, and 3 gallons a minute.
A fourth spring, which is cool and of small flow, formerly issued
from the sandstone at the creek side 100 yards- above the upper hot
spring and formed a drinking pool, but in recent years it has ceased
to be important. In 1909 a frame hotel and about a dozen cottages
provided accommodations for 150 guests, and there is ample space
for the erection of tents.

HOODS HOT SPRINGS (SONOMA 1).
Warm water issues at Hoods Hot Springs in the canyon of Dry
Creek, near the north edge of Sonoma County. The springs are of
small flow and have been used only locally for bathing. They are
probably the same that have been sometimes referred to as Fair-
mount Hot Springs. The rocks in their vicinity, as at Skaggs, are
chiefly crushed sediments, but garnet and glaucophane schists were
observed at a few places eastward along the road.
POINT ARENA HOT SPRINGS (MENDOCINO 33).
Point Arena Hot Springs are situated in the canyon of Garcia
River, about 15 miles by road south of east from Point Arena. The
property has been a resort since about 1895, and in 1910 a hotelr
several cottages, and a number of tents provided accommodations
for 100 guests. A steep trail leads from the buildings, on the canyon
side, to the springs and the stream 200 yards away. Close to the
northeastern side of the stream two hot springs rise in cemented
basins about 6 feet apart and yield flows of about !-£ and 3 gallons a
minute of mildly sulphureted water 112° and 110° in temperature.
The water supplies tub baths in two small houses that are built over
the stream, and a pool in the stream itself is also much used for
bathing. The springs issue in an area of basaltic lava which extends
for about 8 miles northwestward along Garcia River and probably
also for some distance eastward from the springs. In 1910 graphite
was being shipped from workings about 6 miles northeast of the
