was experienced in controlling the flow during construction of the
hotel, the springs now yield only a slight amount of moderately
sulphureted water.
LYONS SPUING (VENTURA 6).
Lyons Spring has been mentioned incidentally in speaking of
Stingleys Hot Springs (Ventura 5, p. 63). It is situated in Matilija
Canyon, about halfway between Vickers and Matilija hot springs,
and about 1 mile northwest of the latter place. The property has
been open as a small resort since 1888, accommodations being pro-
vided in 1908, by tent houses, for about 50 people.
The spring rises in a ravine to the south, and the water is piped
1,100 feet to a small stone reservoir on the grounds. It is thence
piped to a boiler and heated for bathing. It is soft and mildly
sulphureted, being known as a white-sulphur water from the sjight
milkiness that is produced by sulphur in suspension.
SULPHUR SPRING IN MATILIJA CANYON (VENTURA 4).
One other cool sulphur spring in Matilija Canyon has been men-
tioned in the description of Vickers Hot Springs. It rises at the
base of the canyon side, about a quarter of a mile southeast of the
Vickers Hot Springs and supplies a cool, strongly sulphureted pool of
small discharge that was formerly used as a drinking basin. When
visited, however, it had apparently been unused for several years.
The region is composed of shales and sandstones that are probably
of Tertiary age. They are steeply inclined, showing that intense
folding has taken place. The sulphur constituents of the mineral
springs in the canyon, as in many other places, are probably derived
from sulphide and sulphate minerals in the sediments.
SULPHUR SPRING NORTHEAST OF NORDHOFF (VENTURA 8).
A small sulphur spring on the hillside about 2f miles by road
northeast of Nordhoff is probably the one that has been sometimes
referred to as Ojai Sulphur Spring. It is situated in private grounds
on a gentle open slope about 100 yards north of a ravine and rises in a
board-curbed pool 5 feet square and 3 feet deep. Bubbles of gas
intermittently rise in it. The water has a distinctly sulphureted
odor and taste and the dark color of "black sulphur" waters. Small
amounts of sulphur are deposited on leaves and other objects that
expose the sulphide constituents to oxidation by the air. The water
has been used mainly for laundry purposes at the spring. There is
said to be a similar spring a mile eastward, and small sulphur springs
probably issue at other places in this region of Tertiary' sediments.
The rocks of the locality consist of marine sediments, mainly sand-
