Northwards of Karar Khoh, portions of the Karar Khoh series 
are seen in exposures 34 to 38, 11'+ to 21'+ of coal being visible. 
But in this direction the series has evi- 
KaraJKhohserit. Gently been disturbed, for in the tributary 
of the Gae-mara Nala the series must be 
faulted up ; whilst no exposures were found in the Manju Nacha 
Nala (No. 39) at the expected altitude, possibly owing to jungle 
and debris, btit more probably on accoimt of faulting. Time did 
not allow me to examine the multitude of nalas intervening be- 
tween this point and Chitajhor, and it is possible that the thick 
series may be picked up again in that direction. But ifc is 
significant that Mr. Harris, who visited Chitajhor, saw only a thin 
seam (5 to 6 feet) in the Kheradol Nala. In its southward 
extension this series is obviously limited by the cliffs forming 
the southern edge of the coalfield, and, since the Karauli Dhar 
and Diwan Jharia show only 3 to 5 feet of coal in all, it is 
obvious that the series has thinned out to the south, both in 
number of seams and total thickness. A little less than a mile 
due east the Karar Khoh series appears to be represented by 
the Dubpani exposures (12" to 4|' coal), whilst 1| miles to the 
west it is apparently represented by the Paraspani Nala and 
Kachhan Kundi exposures (13" to 2' coal). It looks, therefore, 
as if the Karar Khoh series corresponds with the approximate 
centre of a basin of coal deposition that thinned rapidly in all 
directions, except possibly to the north : where, however, if it
