The San Francisco call. [volume] (San Francisco [Calif.]) 1895-1913, 1895-12-25


Anthony is produced in Kern and San
Benito counties, but is found in several
others. The long wagon transportation
prevents successful competition with that
from abroad and other States. The States
production Will be less than last year.
Asphaltum-Mo than nine-tenths OF
the asphaItum produced in the United
States comes from California, and princi
pally from the counties Of Kern, Santa
Barbara and Ventura. The various de-
posts are opening up splendidly, and
those OF Kern County have reached a
depth OF about AGO feet. Partial returns
indicate large increase over last year.
Bituminous rock is mined extensively
in the counties OF Monterey, San Luis
Obispo and Santa Cruz. The very general
Improvement in the streets of this and the
other cities OF the coast will cause a greater
production than that of 1893
Borax is found IN the counties of Lake,
Inyo and San Bernardino. The greater
part comes from San Bernardino, where it
is mined principally from veins OF cole
mantle. That from Inyo, also part from
San Bernardino County and the State Of
Nevada, comes from superficial strata OF
the so-called salt or soda marshes and
from wells. The States of Nevada and
California have q monopoly in the United
States OF this industry, and California pro-
duces II, 500, 900 out OF total of 100000
pounds. Newspaper accounts and the
fieldmen's notes for 1894 indicate large
increase for this year reasonably certain.
Chronic iron occurs in Alameda, ANA
dor, FL Dorado, Glenn, San Luis Obispo,
Shasta, Sonoma, Tehama and Tuolumne
counties in commercial quantities. but The
bulk Of that produced in 1894 came from
San Luis Obispo, Shasta and Tehema
counties On account OF the cheapness OF
the imported material from Asia Minor
the home production will be decreased this
year.
Clay products-Brick are manufactured
principally in the counties of Alameda,
Los Angeles, Marin, Sacramento, Santa
Clara and Sonoma. Returned prosperity
to the commercial world should stimulate
this industry. and the product for this
year should exceed that OF 1898.
Pottery, terra-cotta ware, sewer.pipe,
etc., are manufactured in the counties of
Alameda, Placer, Riverside and San
Joaquin, while much of the clay en-
ployed therein comes from Amador
County. Large buildings are now con-
structed with steel and iron frames, which
are protected from fire by covering of
terra Gotta ware. The space between the
metal joists is also filed with the same
material, and as building has been un-
usually brisk this year it is expected that
the value of this years product will ex
coed that of 1893.
Coal is found in many counties of the
State, and usually as Ignite. 1t is be-
ing mined at present in Amador, Contra
Costa, Fresno, Orange and Riverside coun-
ties. So far the best coal found occurs near
the line of Fresno and San Benito coun-
ties.
The industry has been comparatively
dormant for several years past, due to the
partial exhaustion of the Mount Diablo
mines. However, the near future looks
more promising, as large tracts of land
lying between. Corral Hollow and Mount
Diablo are currently reported to have been
thoroughly prospected by drill holes,
shafts, tunnels, ETC., and an abundance of
coal found. a railroad from Stockton to
mines at Corral Hollow is now being con-
structed, and it is expected that shipments
will begin in the early spring.
Copper is found in many of the counties
of the State but is not mined, because it is
produced cheaper elsewhere. In the
counties of Calaveras and Nevada copper
cement Containing about 50 per cent of
copper is produced, being precipitated by
scrap iron from copper solution obtained
by running water over the old dumps and
teaching out the copper, which has become
oxidized with exposure and time. The
finer part of the precipitate is roasted and
ground, and is known in commerce as the
anti-fouling copper paint, used on ships
bottoms. The copper INCLUDING cemen0
output is expected to be quite large this
next year in consequence of the extensive
works now being constructed in connec-
ton with the Iron Mountain mines in
Shasta County. The ore is said to carry
about 80 per cent copper and from $40 to
SIS gold and silver per ton. 1t is expected
that the gold and silver will pay all ex-
penses and leave the copper as profit. The
English company which now owns the
property is about completing a narrow
gauge railway from the mines TO the
smelter at keswick, on Clear Creek, eight
miles in length, and thence three miles to
the main line OF the Southern Pacific Com
pany, near Kennett station. This part of
