STATISTICS OP ANNUAL PRODUCTION. 13

Total Mineral Production of California, by Years.
The following tabulation gives the total value of mineral production
of California by years since 1887, in which year compilation of such
data by the State Mining Bureau began. At the side of these figures
the writer has placed the values of the most important metal and non-
metal items — gold and petroleum.
In the same period copper made an important growth beginning with
1897 following the entry of the Shasta County mines, and more
recently Plumas County. Cement increased rapidly from 1902, while
crushed rock, sand and gravel as a group parallels the cement increase.
Quicksilver has been up and down. Mineral water and salt have
always been important items, but the values fluctuate. Borax has
increased materially since 1896. War-time increases, 1915-1918, were
shown by chromite, copper, lead, magnesite, manganese, silver, tungsten
and zinc. Most of these, except silver, have since declined; with
structural materials and copper increasing in 1920-1923, also lead and
maornesite in 1923.
