THE DAMUDA SERIES. 25 



thickness is 5 feet, and it is capped by 3 feet of carbonaceous shale. It 

 dips at as low an angle as 6° to the south-east, and soutli-south-east. 



In the neighbourhood of Chamatu and Choura Jogipilra there is 



no sign of coal, but in the Ganespur river, just 

 Coal near Ganespur. 



after its entrance iiito the field, there is a soam 



exposed measuring 77 feet in thickness and dipping at 15° to the south. 



Above it, there is 36 feet of sandstone; and then a coal seam 

 3' thick. 



The quality of the larger seam is not very good. But the middle 

 portion will furnish a fair amount of coal. A fault running north-west 

 and south-east causes a shift, the downthrow being to the north-east. 



In the Bisanpur river, which skirts the west end of Harhi hill, 

 there are some large seams. The lowest in the series crops out about 

 half a mile from the boundary. The following is the section in ascending 



order : —
