Some of these are merely prospects finding employment for a 



few miners. None of them is equal in size or importance of produc- 

 tion to Pao-p'ing-ch'ang. They are all situated from one to three 

 stages to the south of Pao-p'ing-ch'ang, in the unsurveyed and 

 mountainous country between it and the Yangtze. 



Copper Mines of the Li-chiang Fu prefecture. 



At Yung-pei Ting I obtained the information that the following 

 mines produce copper ores in the prefecture of Li-chiang Fu, which 

 borders the Yung-pei Ting district on the west, 



Hei-pei-shui. 



Ku-ho. 



Lo-tzu-chueh. 



There is no agreement between my list and that given by Rocher 

 30 years before. I was at first inclined to imagine that his *T£- 

 pao-p'ing might be identical with Pao-p'ing-ch'ang, but a Chinese 

 scholar to whom I submitted the characters, says that this is not so. 

 Rocher mentions a mine called Pao-p'ing in the Li-chiang Fu pre-

San-chia-ch'ang Copper Mine. Yi-men Hsien district. (Lat. 24 39'; 

 long. 102 10'; visited April 3rd, 1908.) 



The small copper-producing centre of San-chia-ch'ang is situated 

 ~^ five stages to the south-west of Yunnan Fu, 



in the upper valley of the eastern head- 

 waters of the Yuan-Chiang, the " Red River " of Tongking. 

 Between Yunnan Fu and Yi-men Hsien (stage 3), Carboniferous, 

 Permo-Carboniferous and Red Beds are found, faulted against 

 rocks which I regard as Cambrian on lithological grounds. Around 

 Yi-men Hsien, limestones are again met with, but they only stretch 

 a few miles further west when they are faulted against a series of 

 ancient slates. In the vicinity of San-chia-ch'ang. broken bluish- 

 grey slates form the steep hill-sides, covered with loose screes on
