READER : REPORT ON THE RAMPUR COAL-FIELD. 



with this, little doubt can remain as to its probable correctness. 

 Reasoning similarly with Dr. King's No. 6 borehole the carbon- 

 iferous bands proved can be correlated as illustrated. This correla- 

 tion is of great use in indicating which of the seams proved by the 

 Dhoramuda borehole are exposed in the Lillari nala. For instance, 

 Dr. King (Rec, Geol. Surv. Ind , Vol. XIX page 212), shews 

 that the first coal struck in his No. 5 borehole was the same as that 

 exposed near Khaliabahal and the first in his No. 6 borehole that ex- 

 posed near Bonjari. From the boring record of the Dhoramuda hole 

 one is able to mark out eight seams of coal as appearing to be of 

 workable thickness : — Ft. dee.

On looking at the boring core it can at once be seen that 

 Nos. 1, 3, 4, 5,6 and 7 can be dismissed from

borehole, the Khaliabahal further consideration as of no practical use 

 exposure. whatever, being simply cases of bat, i.e > 



bituminous shales — sometimes grit sandstones included, — raised to 

 the dignity of coal. It is of interest to note, however, that No. 1 is 

 indentical with the Khaliabahal exposure. Now during my work 

 in the field this season I sank a little shaft in this exposure and 

 satisfied myself that it did not contain coal of sufficient thickness 

 or quality good enough to be workable. 

 The section obtained was: —
