COAL EXPLORATIONS. 105 



been extracted lying by the side of the shaft. The heap had certain- 

 ly been weathering for eight or nine years, but nevertheless it bore so 

 great a resemblance to the Durlipali shale bed that I have assumed it 

 to be the same ; no data at present known except perhaps the differ- 

 ence of thicknesses of the seams — which, at such distant points as 

 Durlipali and Luchkura, ought not to be allowed much weight- 

 militate against this assumption, but opinions formed afterwards 

 tended to confirm its correctness. 



Reverting again to horizontal section B of strata near the Eeb 

 river, borehole No. 2 (Luchkura) is seen so placed as to show that 

 the seam it struck was the same as that exposed near Lumchibahal 

 bridge, which I have correlated with my Eeb river seam. Consider- 

 ing now that the distance from Lumchibahal bridge to the shaft at 

 Luchkura is a mile and a quarter and that the rocks exposed 

 between these places are dipping at 5 to the westward, such correla- 

 tion requires corroboration. Until such is forthcoming all that can 

 safely be assumed must be based upon the dips of the rocks. Con- 

 sidering such then we can only say that at the Luchkura shaft a 

 seam of coal seventeen feet thick has been proved, and that, from the 

 dip of the strata, this seam appears to be overlying the coal-seam 

 exposed at Lumchibahal bridge, from which it is apparently sepa- 

 rated by a thickness of from 400 to 500 feet of measures. 



If then the Lumchibahal bridge seam is, as I believe with Dr. King 

 and Mr. Dalby, the same as the Eeb river seam and the Luchkura 

 seam is identical with the Durlipali seam, it follows that the Eeb 

 bridge seam appears to be some 400 to 500 feet or more below the 

 Durlipali seam and this I am inclined to believe is the case. The 

 next borehole, i.e., No. 3, which might have

given some evidence confirming this, cannot, 

 however, be considered, its exact position not being known. 



The Kodopali (No. 4) borehole does not afford any direct evidence
