The- two upper beds are not clearly 

 seen, and thicjinesses are assunaei 

 The lower seam is the only one avail- 

 able, and it is of inferior quality.

A small seam higher than either of 

 these two wiU probably be found 

 nearer BaU HiU : but the only bed 

 available is the 8' 0" seam.

The only ascertained thickness is 

 that of the 3rd seam. At its out- 

 crop in the Khakho, it is strongly 

 spotted ^ith iron pyrites.

AU these are inferior seams of coal. 



I exclude as unavailable all seams under four feet, and those the 

 quality of whose coal would render them unprofitable. 



We thus see that over a very large section of the field, the available 

 thickness is only nine, twelve, and 17 feet, and that such ground as 

 that in the extreme north-east — near Mahtadih and north of the 

 Komaljore Nuddee, — ^may be looked upon as practically barren. 



The coals at Oopurdaha, Lopsadih and Sati ghats, are also of an 

 inferior quality, being shaly and strongly impregnated by iron pyrites. 



Fifteen feet of coal over the whole field, I should consider as not 

 being too small an average. And deducting ^ of the total area for 

 barren ground, and where the overlying rocks are too thick to work the 

 coal profitably, we have 7 >^ 15 == 105 milUons of tons. From which, 

 subtracting one-third for waste and loss by intrusion of trap, &c.j, 

 80 millions of tons remain as the probable available amount.
