Show CALIFORNIA OUTDOES I BED 'DAYS OF GOLD' The days of eo16! in California are nurpasacd, in tho total value of tho stato 's mineral production, by the present era of scientific mining in that state, according to the latest bullotln issued by State Mineralogist Hamilton. In 1013 tho value of California's min-oral min-oral output waa estimated at $100,000,-000. $100,000,-000. In Tcgard to tho crowth of California's Califor-nia's mineral industries, Hamilton says: In tho earlv years of ita existence exist-ence California was n mining Btato, puro and Ktmple. Today tho minor-nl minor-nl industry receives littlo nttontdon from tho public at largo, yot it is greater and moro extensive than in tho palmiest "earliest days." Gold was discovored in 1S48. Tho output out-put for the following voar amounted to $10,151,360. In 1852 ib had grown to n total of $81, 240,700. With tho years succeeding succeed-ing this maximum production tho mines of tho stato continued to yield fabulous wealth, but in decreasing de-creasing amonnts, until their fame became gradually dimmed. Tho low-water marl: of the industr' was reuched in 18S9, when 'the to- -tal mineral output equaled $16.-683,731. $16.-683,731. over $11,000,000 of which was gold. That year also marKoa the beginning of tho present era of practical and Ecioutific development develop-ment of tho varied mineral resources re-sources of tho stato. Improvement Improve-ment in methods of development, troatment aud management has increased tho annual gold production produc-tion to about $20,000,000 a figure which hus approximately hold for the past ten j-cara. Tho discovery and development of oil-boaring territory has been tho largest single factor in the recent re-cent growth of the mineral industry, indus-try, although the building up of tho cement industry, and tho exploitation ex-ploitation of deposits of tho widely varying structural and industrial materials which are now commercially commer-cially produced, havo all hclpod it to reach its present gigantic proportions |
