MISCELLANEOUS MINERALS. 181 



of distillation, that I think there can be no mistake about it, 

 although we saw no specimens *" (Logan Jack, op. cit, p. 178). 



Antimony. 



T was shown specimens of stibnite frequently in Eastern Yunnan, 

 but never met with the mineral in the western parts of the pro- 

 vince. The Director of the Bureau of Mines in Yunnan Fu had 

 a fine series of specimens of the ore. both native and refined. I 

 was told that these came from the Kai Fu prefecture. 



It is a well-known fact that antimony ores occur in this vicinity 

 and also about Kwang-nan Fu on the borders of Kwang-si. 

 Eights were granted by the Government to mine and smelt them 

 in 1909. In 1913, according to the Mcng-tzu Customs reports, 

 427 tons of antimony were exported through that port, and in 

 1914, 335 tons. 



Cobalt 



Leclere states that a cobalt-bearing oxide of manganese is 

 mined in the north of the Tung-chuan prefecture. It has supplied 

 the dyes used in the manufacture of the famous Kuang-si blue 

 porcelain for long periods. (Le., p. 446). 



Marble. 



Ta-li Fu marble is famous throughout China and is used for 

 making ornamental plaques, tombstones, etc. I have visited the 

 quarries which are located on the high mountain wall a few miles 

 to the north- north-west of the city. A crystalline marble crops 

 out in them. It is a fine-grained variety with patches and 

 irregular spots of dark micas and amphiboles in a white back- 

 ground, which produce fantastic effects much appreciated by the 

 cultured Chinese. Large quantities of the stone are still avail- 

 able, but the industry is controlled by the dealers, rather than 

 by the quarry-owners or the polishers. The stone is all prepared 

 locally and is often stained and then covered with a coating of 

 white wax to emphasize the colour designs. 



Semi-precious stone?. 



The jadeite which is worked up in Teng-yiieh comes from the 

 mines of the Mogaung subdivision of the Myitkyina district in
