DETAILED DESCRIPTIONS OF THE RESPECTIVE COALFIELDS. 77 
Government of India, who, up to that time, had worked the collieries 
on royalty, handed them over to the Rewah JJiirbar, under whose 
direction they are now being carried on with much profit to the 
State. 
Korar} — This coalfield is 9^ miles square and lies some 3 
miles north of the Umaria area. Few outcrops of importance 
have been discovered, but a bore-hole put down to a depth of 
63 feet between Kotalwar and Korar proved coal seams, respectively, 
8, 4, 4, and 7 feet thick. The dip is about 9° and a sample of 
weathered coal from the outcrop of one of the seams mentioned 
above yielded the following analysis : — 
Moisture 5-04 
Volatile matter ...... 12-56 
Fixed carbon ....... 65-48 
Ash 16-92 
Johilla. — Coal on the Johilla river was known to occur as early 
as 1840, when Dr. Spilsbury ^ mentions the fact. The measures 
are exposed about 13 miles S. B. of Umaria and constitute two 
tracts, of which only the larger, an area of 11| square miles, is 
known to contain workable coal deposits. The most notable out- 
crop is near the confluence of the Ganjra stream with the Johilla 
river, where shallow borings proved seams of coal, respectively, 17 
and 6 feet in thickness. The inclination of the rocks is moderate 
and the quality of the coal good. The following is the average of 
three analyses given by Hughes : —

outcrops. 
Volatile matter ....... 34-85 
Fixed carbon ....... 54-43 
Ash 10-72 
In summing up the capabilities of the field Mr. Hughes " says 
" There appears to be quite|^20 feet of coal and although the out- 
crop of the seam cannot be traced for more than two miles, it is
