16 HUGHES : KUEHUEBARl COAL FIELD. 



There are not more than three or at most four workable beds, and 

 it is chiefly with a full description of these, at the different localities 

 where they crop out, or have been already worked, that this part of the 

 memoir will be occupied. 



Commencing the notice of the seams systematically from the north- 

 east, the first locality to describe is — 



MohUchuan. — The lowest seam of coal in the neighbourhood of this 

 village is the one that occurs close on the right bank of the Durdurwa 

 at its confluence with a small stream. Its original exposure has been 

 obscured for some years, but its line of outcrop can be pretty accurately 

 laid down by noting the strike of the rocks which are associated 

 with it. 



Where the seam was quarried by the East Indian Railway Company, 

 its direction of dip is north-west. This, however, is not constant, and 

 as the seam extends westwards, there are several variations. Near the 

 bridge over the Durdurwa the dip is north. About half a mile west of 

 this, it is between north-west and north-north-west, and north-west, and 

 still further to the west, there is a southerly bend in the beds bringing 

 the outcrop of the coal round with a north-west and south-east strike. 



The angle of inclination varies in amount from 35° to 6° in differ- 

 ent parts of the seam. There is a minimum of dip close to the bridge, 

 but, as is indicated on the map, there is a rapid increase to the 

 north. 



The thickness of the seam exhibits the inconstancy which is 

 characteristic of the Barakar group. North of Mohliehuan it is stated 

 to be 16' 0", whilst in the workings at Passarabhia it is 12' 6" to 14 

 feet. 



The quality of the coal is undoubtedly good, and superior to that 

 of any other in the field. A specimen of it raised recently is clean,
