a clubhouse and a dozen cottages. A few years ago a large and very
complete bathhouse, with modern apparatus for the therapeutic use
of water, was built adjoining the hotel. These baths are supplied by
a flowing artesian well 10 inches in diameter at the top and 640 feet
deep, that was put down behind the bathhouse and is known as the
Main Sulphur Spring. Its temperature is reported to be 105° and
its yield to be 2,500,000 gallons a day (1,736+ gallons a minute),
but this amount seems excessive.1 The city of Paso Robles has also
erected a bathhouse about one-fourth mile east of Hotel El Paso de
Robles. Its baths are supplied by a flowing well 427 feet deep, which
yields water at a temperature of 105°.

PASO ROBLES MUD BATH SPRINGS (SAN LUIS OBISPO 1).
About 2^ miles north of Paso Robles there are natural warm
springs which are used for bathing. These are locally known as the
Mud Bath Springs. A large amount of warm water here issues about
100 yards from the edge of Salinas River. The springs rise mainly
within concrete walls that were built as foundations for a bathhouse,
but plans were changed and the springs are now of secondary im-
portance to Paso Robles Hot Springs. There is a building at the
Mud Bath Springs, however, below whose floor there are about half
a dozen cemented plunges, with perforated bottoms that admit the
water. About 30 yards west of the bathhouse is a 4-inch flowing
well that in 1908 yielded about 8 gallons a minute of water 118° in
temperature. The water is said to have been struck at a depth of
140 feet. This is known as the Lithia Spring and is used for drinking,
its water being faintly sulphureted and salty. Two natural springs
near by are also used for drinking. One of these, the Soda Spring,
is about 75 yards west of north from the bathhouse. When visited
it was inclosed by a concrete curb and was equipped with a hand
pump, but it discharged about 4 gallons a .minute of warm water.
This water has been carbonated and bottled for several years by the
local soda works. A cool iron spring issues in a ravine 175 yards
northwest of the bathhouse. Water from this spring was piped to
a drinking faucet near the bathhouse, and the overflow, about 1
gallon a minute, supplied a cattle-watering trough hi the ravine.
Southeast of the bathhouse at least half a dozen warm pools and
seepage springs are scattered for half a mile or more along the river
flat that borders the present channel. Mud from one or two of these
pools is used in the plunges at the bathhouse, and two or three of
the flowing springs are used locally for bathing and for laundry.
The following are analyses of several of the springs:
i This amount would be furnished by a vertical discharge pipe 10 inches in diameter above whose top
the water domed up approximately 10 inches.
