MINING EXHIBIT.
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.
