7G COGGIN BROWN : MINES & MINERAL RESOURCES OF YUNNAN. 



the material being converted into coke which is sent to Yunnan 

 Fu. At Si-yang, the northernmost point where coal is worked, 

 the following series is exposed:— 



(h) Hard greyish limestones. 



(a) Bluish dolomitic limestone. 



('/) Greyish sandy shales with coal-seams. 



(e) Yellowish dolomitic limestone. 



(d) Greenish shales. 



(c) Thin limestone bands. 



(b) Red shales. 

 (a) Limestone. 



There are two coal-seams, the upper of which is five feet and 

 the lower between seven and eight feet thick. Both are worked 

 in the usual haphazard Chinese fashion. 



I made another ascent of the scarp from Yang-kai to Ta-wa-tzu 

 (elevation 7,300 feet above the sea), in the neighbourhood of Eul- 

 long-si-chou. Here there are two seams in the same succession of 

 limestones and shales. The strike is north 35° east and the dip 

 westerly at 44°. The scarp itself runs north 20° east, and old coal 

 workings extend along it for miles, confirming the continuity of 

 the seams themselves. According to Deprat, the seams are con- 

 tinuous over a distance of 5 kilometres, the coal is less broken up 

 than in the other occurrences and it yields a good coke for metallur- 

 gical purposes. The seams are free from bands of shale. These 

 localities supply, I believe, coal which is used on the French railway. 

 It is carried to the line on pack ponies. The following analyses 

 are available : —
