Antimony in Other Parts. — China seems wonderfully 

 well supplied with antimony. Her mines near Changsha 

 have been known for years. Here two great bodies of 

 ore are worked. One is 150 miles west and the other 

 about 80 miles northwest. They may have been on the 

 same strike, but this connection seems not to be sub- 

 stantiated. The ore is in limestone and is extensively

worked. The deposits to the northwest are a real vein 

 5 inches to 2 feet thick, having definite contacts with the 

 limestone. Work has been in progress here 20 years, 

 and the shafts are now 200 to 300 feet deep. The body 

 is a nearly perpendicular sheet, and the stibnite is of 

 very good quality. It has a Aveathered zone of antimony 

 oxides, as has the Shiu Chow vein. The other deposit 

 west of Changsha is not a vein proper. Much float is 

 collected, and the mines are in a limestone more or less 

 impregnated with stibnite. No igneous rock is known 

 near either deposit. 



Antimony production is reported from several other 

 provinces. Arranged in order of output, they stand as
