242 SPEINGS OP CALIFOENIA.

In 1909 the water had not been placed on the market.
The country rock of the region is granitic. The spring rises from
a fissure in this rock, which was exposed when the bowldery gravel
was cleared away, before constructing the present basin. Part of the
fissure was closed by cement, in order to confine all of the discharge
to one outlet.

CARBONATED SPRING ON MIDDLE FORK OF TULE RIVER (TULARE 10).
On the northern side of Middle Fork of Tule River, about 6 miles
east of Springville and 1^ miles below the junction of the two main
branches of the Middle Fork, is a small carbonated spring, to which
a trail has been worn down the slope from the road a quarter of a
mile above. The spring forms a.small pool beneath a granitic bowlder
20 feet above the stream. Besides being moderately carbonated, the
water tastes faintly of hydrogen sulphide. A considerable deposit,
which is deeply iron stained, has been formed at the spring, and iron
and a small amount of lime carbonate are also deposited along the
overflow channel.

DOYLE SODA SPRINGS (TULARE 4).
Doyle Soda Springs are on North Fork of Middle Fork of Tule
River, 13 miles northeast of Springville. A flat on the west side of
the stream furnishes a good camping ground, and the place has long
been used as a camping resort.
Two springs, each of which yields about 1 gallon a minute of mod-
erately carbonated water, form pools 2 or 3 feet across, beside a
gneissic bowlder near the western bank of the stream, within 15 yards
of the water's edge. A third spring, nearer the stream, issues from a
crevice in granitic gneiss. Its water is strongly carbonated and
spurts out intermittently from the rock. There is considerable iron
stain near the spring vents. A small amount of carbonate of lime or
magnesia is also deposited by the spray from the main springs, but
the water is probably not highly mineralized. All of the carbonated
water probably issues from the gneiss, which seems to form a belt in
the granitic rock.
CARBONATED SPRING ON SOUTH FORK OF MIDDLE FORK OF TULE
RIVER (TULARE 11).
A carbonated spring of unusually large flow rises on the northern
side of South Fork of Middle Fork of Tule River about 2 miles above
its junction with North Fork of Middle Fork. The yield of this
spring was estimated at about 25 gallons a minute. The water is
warm (77°), strongly carbonated, and tastes faintly sweetish, prob-
ably of iron. A deposit of lime carbonate that is much iron stained
extends to the river's edge, which is normally about 5 yards away.
