proportion of the tracts here covered by alluvium, It is difficult 

 to say how far it extends East. It is extremely probable that it 

 would be found South of the Damuda if sunk for West of the place 

 where the Mtisuria stream runs into the Damuda, about a mile West 

 of Adgaon. 



There can be little doubt that the seam is identical with that of 

 Raniganj. The only difference is the thickening of the lower portion, 

 probably at the expense of the shale below. 



Beneath this seam comes coarse sandstone, probably not above 

 50 feet thick, and then the following section, at the place where 

 the stream running from the North of Morgathi joins the Nixnia.

These beds, with the interstratified coal and carbonaceous shale,

 traced West about a mile as far as a sharp bend of the Nunia, North- 

 east of Theraut, and to the East they wind among the rocky valleys 

 between Morgathi and Raniganj, and are traced up the valley West of
