Io8 READER : REPORT ON THE RAMPUR COAL-FIELD. 



Had these sections been correct, each one of the above seams 

 would have been thick enough to be worked at a profit supposing 

 the coal to be of the average Indian quality. On comparing the 

 record with the boring cores, however, I found that, with the excep- 

 tion of No. 3, each one of these seams had been badly recorded ; 

 carbonaceous and even argillaceous shales had been raised to the 

 dignity of coal to such an extent that the idea of working these 

 seams (except No. 3) could not be entertained. The section of 



No. 3 would be more correct if stated :—

It has been remarked that the object of the Kodopali borehole 

 Dhoramuda, No. 6 was to prove the lower Barakar measures. 

 At present as stated the lower Barakars 

 have not been touched. It was evidently with this object still 

 in view that the Director of the Geological Survey advised the 

 deepening of the Kodopali borehole. Could this have been carried 

 out at the time, a definite opinion as to the value of the field 

 would in all probability by now have been arrived at. Unfortu- 

 nately the boring contractors were not equipped with deep-boring 

 tackle, and when later the work of proving the lower Barakars 

 was undertaken, it was considered a better plan to bore through 

 the whole thickness of the Barakar rocks. Owing undoubtedly 

 in a very great measure to the inaccurate topographical map the 

 thickness of the Barakars appears to have been under-estimated 

 and as a consequence the site of the borehole — Dhoramuda — was 

 chosen, too high, geologically speaking, for the object of the bore- 

 hole to be accomplished with the tackle at hand. 



It must not be understood, however, that this boring has served no 



useful purpose, for it certainly has proved that at this spot and 



consequently at all others on the same geological horizon, the depth 



at which good coal lies in the lower Barakar measures (supposing it
