268 SPEINGS OF CALIFOENIA.
SULPHUR SPUING NEAR BLUE LAKES (LAKE 17).
A small flow of mildly sulphureted water issues in a ravine one-
third of a mile south of Blue Lakes resort, which is 19 miles by road
north of east from Ukiah. The water emerges at the base of a banl-
of gray sandstone into a cemented drinking pool. It was at one time
piped down the ravine to the resort, but in 1909 it was apparently
used only at the spring. A partial analysis of the water, published
in advertising matter, shows it to be mildly mineralized, with sodium
and sulphate predominating.
HAYVILLA SULPHUR SPRING (LAKE 16).
In an open drainage course 5 miles northwest of the town of Upper
Lake there is a sulphur spring whose water has been used to somo
extent for bathing and drinking. It has become known as Hayvilk.
Sulphur Spring, from the name of the ranch on which it is situated.
When the place was visited the water rose from buff-colored sand-
stone near the drainage wash into a small rock-walled drinking pool,
and was piped to a bathtub a few yards away. The water is notice-
ably sulphureted and has a slightly alkaline or saline taste.
In connection with the Hay villa Spring, two other sulphur springs
in the same region, which have already been described, may be men-
tioned here. One of these is about 3 miles westward, on the property
of the Witter Medical Springs Co. (p. 177); the other is at Saratoga
Springs (Lake 18, p. 179), about 3 miles southward in a direct line.

SULPHUR SPRINGS IN SULPHUR VALLEY (LAKE 43).
Two small unimproved springs that are noticeably sulphureted
lie in Sulphur Valley, in southern Lake County, 2 or 3 miles north-
east of Glenbrook post office. One of these springs is on the Ogden
ranch, and rises near a small spring of distinctly carbonated water;
the other, which is some distance westward and is known locally as
the Deadshot Spring, is alkaline and saline, as well as sulphureted,
and its water is said to have been used for curing deer hides by putting
them to soak in the spring.

ZEM ZEM SPRING (NAPA 1).
A small spring of strongly sulphureted water is situated near the
road between Knoxville and Monticello, about 5 miles southeast of
Knoxville. The spring was of more importance during the days of
active mining in the Knoxville district than it is now, but it is still a
camping place for teamsters. The water is too highly mineralized,
however, to be palatable, an early analysis 1 indicating a content of
21,000'parts per million of total solids.
