80 HUGHES : KURHURBAUf COAL FIELD. 



The next seam is a shaly coal of 3' 0% with shale above and 

 below it. 



About 12 feet of sandstone separates this from another bed which is 

 only partially exposed in the rivulet. It had been cut into by the East 

 Indian Railway Company, and is stated to be a hard;, stony coal, and not 

 worth working'. The thickness is 4 feet, and its dip is 10° to the N. 



A thin bed about 1" to 8'^ occurs above this near the faulted bound- 

 ary; a thin band of shaly coal, 18 inches thick, with coarse grey and 

 brownish sandstones, exhibiting a reverse dip to south by east^ was vi&ible 

 in 1859. 



None of these seams either from their thickness or quality judged by 

 the evidence at their out-crop, are worth consideration ; but, before con- 

 demning them, it would be well if the proprietors in whose land they 

 occur, tested, by borings and trial shafts, their behaviour under ground. 



Being, as these seams are, the representatives of the thick beds of 

 coal met with elsewhere, they may possibly increase to a workable thick- 

 ness along other portions of their strike. The probability, however, is 

 ao-ainst their doing so, as the rocks associated with them show a tendency 

 to thin out in the direction of Bayra, and the out-crops of carbona- 

 ceous shale also exhibit a diminished thickness. 



Bayra nullah. — Two out-crops of black shale are seen, dipping 10°. 

 They occur on the strike of the Kumarsote seams. 



All the places at which coal crops to the surface, or has been 

 discovered by the sinking of bore-holes or shafts, have now been noticed. 

 The conclusions which may be drawn from the information con- 

 tained in the preceding pages, I have reserved for the summary at the 

 end of this memoir.
