SOHAGPUK COAL-FIELD.

north of Siinhat, the capital of Korea, amongst the supra-Barakar sand- 

 stones, and enters the field of the true coal-measures in the vicinity of 

 the town. Its course and that of many of its feeders lies in great part 

 in a hilly and impracticable country so far as communications are con- 

 cerned. In consequence of this physical drawback connected with the 

 coal-measures, the value of the different bands of coal is so reduced that 1 

 have curtailed my notices, and have passed by all but the larger and 

 more important seams with very brief allusions. All the details of 

 locality necessary to again find the outcrops that we met with are in the 

 Chapter of Appendices. 



The Barakars are contracted in width in the Korea State owing to 



Productive measures denudation, and the chief feature in the distribu- 

 in south of field. ^ion of the coal is, that the productive measures 



are confined to the lower horizon of the group, forming a narrow zone 

 along the southern border of the field. 



Before describing the Korean portion proper, there are two streams, 



Kulharia and Jhiria the Kulharia and the Jhiria, tributaries of the 

 streams. Hestho, that rise in the Rewah State and which 



I should first treat and dispose of. Being tributaries of the Hestho, 

 I left them for notice with the drainage system of that river, but the 

 accident of local position throws the coal-measures that are exposed 

 in them rather out of harmony with the restriction of the fiscal limits 

 of the Korea State. 



There are two seams of coal, of which the upper is exposed close to 



Bhalmuri Dumarka- the village of Bhalmuri, measuring 5 feet 4 inches, 

 cbar, seam 5' 4". The direction of dip just at this locality is to the 



south, but the rocks undulate, and the seam is again seen near Dumar- 

 kachar. The lower seam is visible at the confluence of the Kulharia and 

 the Jhiria at the foot of a waterfall. It is capped by greyish-white 

 felspathic sandstone, very soft at the surface with felspar decomposed ; 

 there is here and there a slight tendency to ferruginous segregation, but 

 not nearly to such an extent as in the regular Mahadevas. I make this 

 allusion as a warning, for, though the presence of iron is a very essential
