SOHAGPUR coal-field.

Higher in the series are two or perhaps three small beds of coal, 

 Small seams in various * ne outcrops of which have been met with in 

 nvers - the Nagaua and its tributaries, and also in the 



Ghorbei, Gurrha, Kanuahi, and Khairi streams. Not one of these 

 strikes me as being of much importance ; the greatest thickness in' 

 no case exceeds 3 feet 4 inches. Several of the outcrops are at the 

 Seams at base of ' )ase °^ waterfalls, and whilst our survey was 

 watcrialls. progressing, this connection of coal with each 



abrupt fall in the level of the rivers was found to be of constant occur- 

 rence ; during the later years of our labours, we took advantage of 

 this circumstance to diminish the toil of speculative wandering. 



I am inclined to think, as I have already said, that the Nandnah 

 seam crops out at the mouth of the Khairi and Kunuk rivers, but the 

 sections are very imperfect. The first one, just at the junction of the 

 Khairi with the Son, when roughly measured, gave (descending) —

Some of the coal was submitted to examination in the laboratory, 

 but the results obtained were not encouraging. 



In the Kunuk, the seam is but partially seen, and the exposure is 

 4 feet 9 inches to 5 feet. It cannot be traced far, and in all directions 

 there is a great abundance of trappean matter, which covers up the rocks. 



Of the small seams higher in the series on the right side of the Son, 

 there are representatives or the actual continuations on the left side of 

 the river within the holdings of the villages of

JNot one or them exhibits a greater thickness than 

 1 feet 6 inches. The dip varies, being both to the north and south, but 

 the angle throughout is small, only very occasionally rising to 8 degrees.
