In this section the last seam alone contains coal which could be 

 extracted profitably ; the greater portion of it being covered by water, 

 it is impossible to say what the total thickness of burnable coal may be. 

 The dip 20° however is rather high for the present methods of work- 

 ing practised in Bengal. Some distance up the river we meet another 

 seam of carbonaceous shale four feet thick ; it is coaly towards the 

 top. At the further end of the same reach in which this seam occurs 

 are two seams, separated by a band of sandstone one foot thick. The 

 lower one consists of two feet two inches of coaly shale ; the upper one 

 is obscured by fallen masses of sandstone, so that its thickness could 

 not be determined. 



"We now return to the examination of the Damoodah and its tri-. 

 butaries west of the Poonoo Road ghat.
