the Damuda, and from the railway, it can scarcely be worked at a 

 profit, but in the years 1858-59, owing to the great demand for coal for 

 the East India Railway, between the Adjai and the More, large quan- 

 tities, even of the inferior portions of the Kasta seam, were quarried, 

 and carried in carts to Sainthia and Surul (Soorool). 



The tract of alluvium North of the Adjai, and South of the villages 

 of Afzalpur, Bara, Raswan, Hazratpur, &c, is, doubtless, under-laid 

 by rocks of the Lower Damuda series ; and borings near Parsundhi, 

 Tamra, Samiildhi, and Binanpur, may show the presence of coal seams. 

 About Seria (or Sira), Jamalpar, and Lobasan, it is very possible that 

 ironstone shales may occur, or they may extend even farther to the 

 North. But their position can only be conjectured. 



South of the Adjai, the area occupied by the Lower Damuda group is 



considerable, and it increases gradually to theWest-

nearly the whole area is occupied by these rocks. In describing this 



large tract of coal-bearing rocks, it will be most convenient to speak of the 



various localities in succession, commencing with the most Eastwardly.

 Lower Damuda rocks, cutting out all beds below the ironstone shales ;

worthless for economic purposes.
