38 HUGHES : KURHURBARf COAL FIELD. 



bore hole on the left bank of the stream. The strike of these beds will 

 be found to change inland of Sati ghat, keeping more or less parallel 

 with the curve of the boundary. 



Mamnudcli, — Two seams occur here^ but only the lower one is work- 

 able. The section is : — 



1. Top soil, &c, 



2. Coal 



3. Sandstone 



4. Coal ... ... ... 9 to 



5. Sandstone . 



The larger of the above seams was the bed worked by Mr. Inman. io 

 some extent in 1851-52^ and was the first coal which was systematically 

 mined in the field. It is seen out-cropping in the bed of a small stream 

 close to Mr. Inman^s shafts and is about 3' 6"' at the surface. It^ however, 

 increases rapidly, as the above section shows, to 9 and 11 feet. The dip 

 is 10° to the south-east. The Bengal Coal Company are now driving 

 galleries and raising coal which is of good quality, and little inferior 

 to that of the Mohlichuan seam, which they are .working in their 

 Kuldiha property. 



A fault occurs near the mouth of the shaft striking north-west — 

 south-east with a down throw to the west. This seam would appear, to be 

 afiected by more than one fault, as search was made for it in the 

 direction of the dip by the East Indian Kailway Company, who own the 

 adjoining ground, but without success. It is possible, however, that 

 the borings may not have been carried down to a sufficient depth, 

 too small an angle having been allowed for the inclination of the 

 rocks. This is a fruitful source of discrepancy between calculated 

 and actual depths, and although it can only be guarded against by 

 care, the error should be avoided by making rather an excessive than 

 a deficient allowance for dip.
