The seam can be traced both east and west, and a bore-bole was put 

 down (1882) near the junction of the Marjada and 

 Umarha streams, where the coal appears in great 

 force. The section agrees closely with that of the Johilla boring —

Sandstone and carbonaceous shale — 

 Angle of dip is 6°, direction nearly due north. 



From this point westward I failed to procure further evidence of the 

 existence of this seam, but I have strong faith in its extension, and also 

 that, when circumstances render it a matter of importance to follow it up, 

 it will be found to occur under the Lametas of the Marni Nala. 



For the purpose of having the coal practically tested, 500 maunds 

 Coal quarried for trial were V>«*™* from the out-crop in the Marjada 

 on railway. Nala and delivered to the Great Indian Peninsula 



Railway for trial in their locomotives. 



Average samples selected by myself gave excellent percentage figures, 

 and for comparison with those of Umaria coal I append a few analyses of 

 each.
