CHAPTER IX. 



MINING. 



216. Mining Products. Mining was until about 1860 

 the chief industry of the State, but it has now been surpassed 

 by both agriculture and manufactures. The annual products 

 of mining in California may be thus stated : Gold $20,000,- 

 000, lead $300,000, silver $1,000,000, quicksilver $3,000,000, 

 coal $800,000, borax $100,000, asphaltum $50,000, petroleum 

 $10,000, sulphur $50,000, and copper $100,000. The pro- 

 duction of petroleum and borax is just commencing, and the 

 yield of sulphur and copper is very irregular. The total is 

 $25,400,000. 



217. Number of Gold Miners. We have no official 

 statistics of the number of gold miners in California, so we 

 must ascertain the number by calculation from various sources. 



The number of votes cast in 1872, and the number of 

 Chinamen in the gold mining counties in 1870, were the fol- 

 lowing :
