Under the emperors K'ang Hsi, Yung Cheng, Ch'ien Lung 

 and Chia Ch ? ing (1637-1823), the province contained fifty-four 

 mines, most of which produced copper and could furnish in full 

 production over 5,000 metric tons of the metal. The production of 

 copper in 1896 is stated to have been 1,850,000 catties or 1,110 metric 

 tons obtained from the following mines : —
