highest measured. Water boils at 204° at the elevation of the pool
(4,400 feet), and it is probable that it rises with this temperature in
the spring. The measured discharge was 325 gallons a minute.
The water is used several hundred yards away as a domestic supply
and for irrigation. A small area near the spring and between two
outflow streams is used for growing tomatoes. The water has no dis-
tinctly mineralized taste, though it is said to stimulate the action
of the kidneys.

HOT SPRINGS ON HOT CREEK (MODOC 6).
About 8 miles north of east from Kellys Hot Spring a stream known
as Hot Creek is formed by numerous thermal springs that rise on the
north side of the valley that borders Pit River. A maximum tem-
perature of 92° was recorded here, at the side of a small house used as
a laundry and for bathing. The stream, which carries approxi-
mately 700 gallons a minute, irrigates meadow land along its course
of a mile to the river. Half a mile northeast of the main group an-
other spring, with a temperature of 85° and a yield of about 8 gallons
a minute, has been used to irrigate a potato field.
WARM SPRING IN WARM SPRING VALLEY (MODOC 5).
About halfway between Kellys Hot Spring and the springs on Hot
Creek, a spring issues in Warm Spring Valley on gentle slopes that
border a northern extension of the valley along Pit River. The
temperature measured in this spring was 81°, and its flow was
approximately 275 gallons a minute. The water is employed for
domestic uses as well as for irrigation. The following analysis shows
it to be a slightly mineralized water of the primary alkaline type:
