THE DAMUDA SERIES. 19 



hig-hest portion of the group; elsewlierOj the sandstones and shales 

 immediately underljing" the Ironstone shales are of the usual felspathic 

 and silicious variety which is characteristic of the Barakars. 



The intercalated ferriferous shales can be traced from Passaria to 

 Dokatand, and no further. They are local in their development. 



There are no outcrops of coal to be seen in the part of the field 

 which I have just been describing*, indicated by the villag-es of Passaria^ 

 Koilan, Dokatand^ nor Nappo ; but there is no doubt in my own mind 

 that coal does exist ; and that if search were made for it by boring-^ we 

 should find it at its usual horizon. The dips near Naj)po.and the other 

 villages are loWj and. very favorable for the working of the coal. 



The BadmdM river which flows past Gondalpara and Badam^ 



exposes a very clean section of the rocks, nearly 

 Badmahi river. 



opposite the former village. The measurements 



which I made are as follows : —
