92 BALL AND SIMPSON : COALFIELDS OF INDIA. 
Near Lokartalai on the Moran, at the western extremity of the 
basin, where some carbonaceous outcrops occur, borings were put 
down to depths of 254, 84 and 88 feet, but without proving coal. 
In the open valley of the Tawa on the south of the basin at Kesla, 
on the Betul and Hoshangabad road, borings to the depth of 302 
and 241 feet had the same result as the boring at Khapa. 
Other borings between the Piparia and Bunkheri stations, on 
the Great Indian Peninsula Railway, and Pachmari, although sunk 
in deposits belonging to the Upper Gondwanas, close to Talchir 
outcrops, failed to reach the coal measures, which are there con- 
sequently overlapped. 
Mohpani} — The Mohpani coalfield is the most northerly of the 
several small coalfields of the Satpura-Gondwana basin, and for 
many years it was the only one of them which had been extensively 
worked. It is situated in the Narsinghpur district of the Central 
Provinces, and lies on the south of the Narbada alluvial valley, 
at the foot of the northern spurs of the Satpura hill ranges. The 
exposed coal-measures (Barakars) occupy an area of rather more 
than one square mile. Their limits are ill-defined. On the south, 
they pass under younger rocks, and on the east and west they are 
overlapped by the same deposits. The northern limits of the field 
are obscured by the Narbada alluvium. There are four seams of 
coal with average thicknesses of 17, 25, 5 and 6| feet respectively. 
The average analysis of a number of samples of the coal recently 
assayed in the laboratory of the Geological Survey of India, is : —

The coal has only occasionally a caking quality. 
A recent estimate has fixed the amount of workable fuel at 
rather more than 8 million tons, but further exploration may 
considerably augment this total.
