of sandstone and shale. Deprat states that there are at least 

 four seams varying in thickness from ty to 5J- feet. The strike 

 at the mines is north-east to south-west and the dip at a low angle 

 to the south-east. In the hills to the north-west, I found horizon 

 (c) again and I believe the coal-bearing stratum is to be found there 

 also. Most of the coal is coked on the spot and then sold in Yunnan 

 Fu for domestic purposes. It is transported to the capital by 

 junks. At the time of my visit to Yunnan Fu it was proposed to 

 use the coke in the Imperial Mint and Arsenal. Analyses of the 

 coal are given in the following tables : —

 Hsin - tsun - mile between Hai-kou and Hsin-tsun, the coal- 



bearing sandstones can be seen high above the river and they are 

 doubtless prolonged further to the south-east in the direction of 

 the lake. Near Hsin-tsun I found the following sequence, the rocks 

 themselves being nearly horizontal : —
