SULPHUR SPRINGS. 259
slight, but small amounts of white algous growths on the banks and
strings of bubbles that rise in the creek make the locality easily
noticeable. Sandstone and shale that dip about 10° N. are exposed
at this place.
MUER SPRINGS (MENDOCINO 11).
On the edge of the valley about 4 miles northeast of Willits natural
gas and a small flow of water have been obtained on the property of
Mr. A. J. Muir. A collecting tank covers a small pit in which gas
rises and is used for heating and lighting the residence a few hundred
yards away, and a natural spring rises near by that yields about 5
gallons a minute of mildly sulphureted water with a slight oily
taste. A well was drilled 150 feet deep, close to the gas tank, in search
of oil or a greater supply of gas, but obtained only a flow of cool water.
This part of the valley is underlain by dark shales from which
natural gas is said to escape at several other places along the eastern
side of the meadow land.

SULPHUR SPRING NEAR LAYTONVILLE (MENDOCINO 4).
A spring that yields about 200 gallons a minute rises near the
barnyard of Mr. Samuel Pinches, half a mile north of Laytonville.
The water issues on a gentle slope at the base of a steeper hillside,
from several vents in a small depression. It is locally called a sul-
phur spring, and a small amount of the algous growth that is common
in sulphur springs grows along the outflow channel, but the water is
only faintly sulphureted. It has a distinctly mineralized taste as of
sulphates, however, and inflammable gas rises with the water. A
small bathhouse is supplied by the spring, but little other use has
been made of the water. The rock from which it rises appears to be
a crushed quartzitic sandstone, and the topography suggests that
the spring rises along a slight fault.
SULPHUR SPRING NEAR BRANCH OF EEL RIVER (MENDOCINO 3).

A small spring of distinctly sulphureted water rises in the barn-
yard of Mr. Mitchell's ranch, on the southern side of a branch of
South Fork of Eel Kiver, about 13 miles by road and trail northwest
of Laytonville and 1 mile northwest of Petersons Mineral Spring
(Mendocino 2, p. 177). The spring has not been used for drinking or
for other purposes, but it is of interest from the fact that its water
was rendered milky by clay for a week following the earthquake of
April 18, 1906. It issues in a marshy patch near the base of dark-
colored sedimentary rocks. 9
