62 HUGHES : SOUTHERN COAL-FIELDS OF REWAH GONDVVANA BASIN. 



element in characterising the sandstones of the Mahadevas, it often plays 

 a prominent part, but not to so great an extent, in varying the appear- 



ance of rocks that do not belong to that group.

Then sandstones to the end of the section where the road from Bhauta 

 to Jhagrakhand crosses the stream, and where Talehirs are brought up 

 by a fault. Owing to the undulations of the strata the seam is repeat- 

 edly exposed to view for about a mile and a half in the bed of the stream. 

 The analysis made by Lala llira Lai, of what was selected as an average 

 sample of the coal, gave — 



Moisture ......... 6'7 



Volatile matter 28-2 



Fixed carhon ......... 59"fi 



Ash .......... 5*5

It does not cake. Ash reddish in colour. 



This is much more favourable testimony to the excelh nee of the coal 

 than I anticipated ; the smallness of the ash is remarkable, and for the 

 future credit of the Sohagpur field, I hope this amount of 5'5 per cent, 

 will never be exceeded by this seam. With such fuel as this much 

 might be accomplished, but, unfortunately like most good things, it is 

 not to be easily obtained, being 86 miles further away from a line of rail- 

 way than Umaria. The continuation of this

towards the Jh:\p-akhnnd seam is met with both to the north in the Jhagra- 

 khand, and to the south in the Neori, 2 miles 

 south-east of Tanki village. My colleague, who traced it in the latter 

 direction, states that 6' V are exposed and the rest hidden under water. 

 There is a thin parting of shale, and the quality of the coal is good.
