and West. f ironstone. This run can be traced without a 



break, from South of Maitani to near Chinakuri village, and recurs 

 South of the Damuda. It appears to be concealed by alluvium close to 

 Chinakuri village. 



Probably the coal seam is overlapped by the base of the Panchet beds 

 near Patmani : the ironstone and shale disappearing, doubtless, from the 

 same cause, somewhat further East, near Digari ; and appearing to be 

 faulted near the spot where it is overlapped ; but this is doubtful. 



To the West the Chinakuri seam has not been traced beyond the 

 brook West of the colliery, and it is stated that Mr. Betts bored to a 

 depth of 250 feet, without finding coal. No fault, however, can be made 

 out to occur, and very little depsndence can be placed upon reports of 

 borings, the exact locality of which is not known. They may have 

 been outside the out-crop : still it is quite possible that a fault exists. 



No rocks are seen for some distance above the Chinakuri coal seam, 

 which does not appear to be more than 200 or 300 feet below the base 

 of the Panchet beds. 



VII. Country South of the Damuda. 



West of the Barakar, and North of the Damuda, no rocks are seen 

 in the small area of Raniganj beds which are found there. The rocky 

 island at the mouth of the Barakar is entirely composed of sandstone. 



The description of the beds South of the Damuda will commence 



CMnch and Barakar most conveniently in the neighborhood of those 

 faults - last alluded to, and, consequently, from the West 



where alone, on the right bank of the river, the lowest beds of the 

 Eaniganj series are met with. The two large faults, one passing by 

 Chanch, and the other down the Barakar, are not clearly traced to the
