The Mining Department of the display on the main floor of the
California Building was attractively installed and as complete as the
State has ever made, being strong in the minerals in which we are
strong, but embracing in all forty-four separate commercial varieties,
including a strong showing of mineral oils and structural materials. A
beautiful illuminated case of gold specimens and free gold ores from
Siskiyou County, and an equally beautiful illuminated case of rough and
cut gems from San Diego County, including gem jewelry, constituted very
attractive features of the mineral department. The onyx and onyx ware
from San Diego made a fine showing, as did also the large display of
slate in all forms of utility from El Dorado.
