This is the most promising seam in this part of the field, and though 

 I can assert nothing positively about the goodness of the coal or the 

 real underground relative thickness of the shale, I am inclined to form a 

 favorable judgment of its worth and to hope that the shale may diminish. 



In the Kunuk there is a 4-feet seam of moderate quality below the 

 „, „. outfall of the Dhoran, and then there is a lone;

appearance of true coal. As its head waters are neared, however, there 

 are numerous subsidiary streams, and in them, as also in the Kunuk, 

 there are some outcrops of carbonaceous matter. 



All of them, with the exception of a 3-feet seam of coal south-west

their thickness at the surface recommends them. 



The rivers examined were those flowing past the villages of Kumer- 

 hin, Delbhakherua, and Khamaria, and falling into the Kunuk on its left 

 bank, and the Bichli and others on the right bank.
