and towns of a hfty-mile belt of the mother
lode with light and power, and railroad is
advancing into the same region to help along
the new thrill OF life.
Trinity County and western Siskiyou ara
growing in mining population at rapid rate
and great numbers of new mines are being
opened and much capital invested. A similar
new life and promise pervades the gold regions
of the whole State.
One of the most notable events in the re-
cent history OF mining development in Cali.
fornia will occur this week when the power
wheels and dynamos of the Blue Lakes power
plant turn for the first time. The Blue Lakes
Water Power Company expect to set the great
plant going on Tuesday.
This big electric power enterprise will SIM
ply mines with power and light for fifty milex
along the mother lode in Calaveras, Tuolumne
and Mariposa counties, and by affording
cheaper and more convenient power win
stimulate mining operations. The California
Exploration Company, which has bought or
bonded fifty or more mines throughout this
region, is the first and the principal customer
of the power company, which is under con.
tract to supply several thousand horsepower to
the Exploration Company in the very near
future. The Exploration Company will begin
using the power at once, and the distribution
will increase and extend as fast as poles. lines

company has not yet accepted contracts with
others than the Exploration Company, but
many other mines will be supplied as fast as
the plant and its facilities can be developed,
Poles and wires are now up for distance of
seven teen m lies from Blue Lakes, and several
towns, including San Andreas and Mokel-
umne Hill. have been wired for Lighting. The
plant is located at the foot of a steep incline
and the water is conveyed in pipes from the

The plant is being arranged for Is. 900 horse
power at the start and nearly 1000 horse
power can be developed in the future. 1t will
be the most notable experiment in supplying
electric power TO large number of mines.
