hughes: KURHTJRBARf COAL FIEUD. 38 



as the boundaries of the field have now been determined with sufficient 

 nicety to calculate the area of the Barakar group, we might, did these 

 seams overlie each other continuously, readily estimate the amount of 

 coal which existed. 



Accepting the thickness of the three seams at Passarabhia as 33 

 feet, and the area of the Barakars as 8| square miles, they would contain 

 about 2,720 millions of tons. 



I have, however, already pointed out that the principal seams 

 exhibit an irregularity in their sections — a characteristic of the Barakar 

 group wherever it is developed. 



Examining this point more in detail, we find that at Passarabhia 

 there is an excessive accumulation of carbonaceous matter which 

 diminishes in every direction from that spot, at Buriadih, at 

 Chunjka, at Kope, at Domahani, Oopurdaha, Lopsadih and Sati 

 ghats, at Ramnuddi and in the Koomarsote nuddi. In all the 

 localities enumerated above, although at some places the seams have 

 become so reduced, and the aspect of their sections so changed, that it 

 is difficult to correlate them, still the general horizon at which they 

 occur in the series shows that we have seams representative of the beds 

 at Passarabhia. 



The following table gives a ready idea of the thickness of these 

 seams in various parts of the field : —
