white settlers along the lower course of the stream, but only a small
part of the supply has been employed. The water of Lost Creek*
normally sinks at a distance of about a mile above its junction with
Hat Creek, or about 2^ miles in a direct line west of south from Great
Springs, and it is locally believed that the creek reappears in the
springs. The position of the springs at the northern base of slopes
that rise to Lassen Peak and the fact that the water issues almost
entirely on that bank of Hat Creek which is toward the mountains
indicate, however, that the supply comes mainly from melting snow
on the slopes to the south, though a part is perhaps derived from
Lost Creek. The yield of the springs is said to vary somewhat with
the season, a characteristic of springs that have near-by sources of
supply.
BOCK CREEK SPRINGS (SHASTA 13).
Several cold springs of large flow issue on the western slopes of Las-
sen Peak. Among them are Rock Creek Springs, which are near the
headwaters of the stream of the same name. The water issues from
a hard lava agglomerate at a rate of about 11 cubic feet per second
(4,950 gallons a minute). This water has been appropriated by the
Northern California Power Co. for use in generating electric power in
their plant near Manton, several miles west of the springs.

BIG CLIPPER SPRINGS (TEHAMA 1).
Big Clipper Springs are similar in character and mode of occurrence
to Rock Creek Springs. They issue about 4 miles in a direct line
southeast of the latter, beside a tributary of Digger Creek, and yield
a flow of about 5 second-feet (2,250 gallons a minute). Their water,
like that of Bock Creek Springs to the northeast, has been appropriated
for electric power generation by the Northern California Power Co.
The positions of both Big Clipper and Rock Creek springs and their
large and nearly uniform flows indicate that, like other large cold
springs in the region, their source of supply is the melting snow of
Lassen Peak. The springs issue from layers of tuffaceous lava or
lava agglomerate through which the water very probably percolates
westward from the higher slopes until it finds surface escape in the
creek canyons.
LARGE COLD SPRINGS ON GERBER RANCH (TEHAMA 4).
On the Gerber ranch, which is beside the stage road between Red
Bluff and Paynes Creek post office and about 20 miles east of the
former place, springs of considerable flow issue in a small meadow
along the course of Paynes Creek. The water has supplied a small
pond and has been used to some extent for irrigation. It is evi-
