1914 of S2,161,653 Dredges are also
in operation IN the counties of Gala

OF the 30 counties producing gold
in California in 1914, yielded over
1000 900 each, as follows: Nevada,
$3.301 ,94S; Amador, $3,082, ,002; Yuha
$2,S00,713; Sacramento. $2,164 ,49l;
Butte, $1.697, ,120; Calavcras, $1,336,
S75, and Shasta, S1,1O1 ,202. The lead
ing hydraulic mining county was
Trinity; the county producing the
greatest amount of gold from drift
mines was Placer, and the leading
dredge mining county was Iuba. Ne
vada county was the leading producer
of gold won by deep mining, and it
was this county also that made lar
ger increase than any other in its
gold yield in 1914, as compared with
1913. namely, $S83,215.
OF the total ore milled in Califor-
MIA from deep mines, 1,243,529 tons,
or 50 per cent, came from the mines
in the 5 Mother Lode counties of
Amador, Calaveras, FL Dorado, Mari
posa and Tuolumne. This ore yielded
on an average, in gold and silver, $5,-
G75,552, or $4.08 Per ton.
The 629,O37 tons of ore from Anna
dor county yielded $3.50 per ton, but
the S59,5O9 tons from Calaveras coun-
ty averaged only $2.32 per ton. The
average value per ton in FL Dorado
county was $4.95; in Mariposa, $919,
and in Tuolumne. 1924.
The mine production of silver in
California in 1914 was 1,471,S59 fine
ounces, valued at $S13,93S. On this
1,436,982 ounces was won by deem
mining The larger part of the out
put, 1,267,752 ounces, valued at SOL,
067, was derived from crude smelt-
ing ore. The greatest output was
made, as usual, by Shasta county,
where the yield from the smelling of
copper ores was 592,727 ounces, val
ued at $327,77S; from siliccous ore
1920 ounces, and from placers, 1907
ounceS-a total for the county of G26.-
954 ounces, valued at $3l6, 7O6. Inyo
county follows Shasta in the produc-
tion of silver, with an output of I66. :
575 ounces, valued at $25S,O16, mainly
from silver ores and silver-lead ores.
There were silver mines worked in
the state in 1914-more than in many
years. The 6 silver-ead mines in the
state produced 44S,054 ounces. Only
small amount of silvcr-34,S77
ounces-was obtained with the placer
gold of the state.
The copper produced from Califor-
MIA ores In California in 1914 wa
aO.5O7,692 pounds, valued at Sl.057.-
523-a decrease of 4,O67315 pound
IN quantity and $1.30l .603 in value.
1t Is this deficit in values which ac-
counts for the decrease in total value
of the metallic output of the state
In 1914. Copper wa produced in
Amador. Calaveras. Imperial. Inyo.
Marposa. Mono. Placer, Plumas. Riv-
erside. San Bernardino and Shasta
counties. Shasta. a. usual was the
heaviest producer, but in that county
there was a decrease of 1.Sl5.62S
pounds in quantity and S4O.4l9 in
value. The smelter fume Htjqation
stlll keeps several of the large smelt
ing plants idle, only one of the Shas-
IA county Smelters. the Mammoth at
hennett, having been operated. The
Mountain Copper Company OF that
county was idle for several months
IN 1914, because of the war. The En-
gels Copper Company of Plumas
county. operating in a forest reserve
and unable to stait its smelter. ha
adopted the flotation process and
brought Plumas county within the
copper producing column for the first
time IN its history, although there arc
many known and partly developed cop
per deposits in the county.
The yield of lead in 1911 va 4.251.-
923 pounds, valued at Sl65.S25. an
increPse in quantity of 1881 pound
and in value Of $1l 1914. Most of the
lead was derived from Inyo county.
although some came from Shasta.
Kern and Placer counties.
The zinc production in 1914 was
@89,47l pounds, valued at S19.S69. In
1911 only 3 mines produced zinc. all
In lnyo county.
The two largest gold producing deep
mine camps in the state arc Grass
