DAMUDA SERIES. 35 



Not only are the beds disturbed, but the small area is limited on three 

 sides by the gneiss, and on the north it is covered by the Burgo hill, con- 

 sisting of the upper rocks capped by trap. These beds re-appear again 

 from under the hill in the valley north of Burgo hill, where they exhibit 

 the same characters ; no bed of good coal has been detected there either. 



For upwards of two miles beyond the place where the section given 



above is exposed, the river passes through meta- 

 Bansloi river section. . 



morphic rocks ; but at the top of the north and 



south reach, beyond Salungi, sandstones are again met with. At the 



loop bend, north of Khurkasol, there is a band of carbonaceous shale : 



but no trace of coal is seen. Between this and the neighbourhood of 



Ranga, where the trap first comes in, the section exposes sandstones, 



pebble beds, and carbonaceous shales, the same beds being constantly 



repeated. South of the river there are several seams of coaly shale and 



inferior coal. Wherever there appeared to be the slightest chance of 



coal being found, the outcrops have been excavated and water is lodged 



in the hollows, so that it is difficult now to form an accurate opinion as 



to the thickness of the seams, or the character of the coal. North of 



the river, at Chilgo, Dangapura and Bankijor, there are some similar 



seams. The position of all of these is indicated on the map. In the 



chapter on the Economic Resources I shall detail whatever has been 



ascertained regarding the coal at these several localities. 



North of, and close to, the road traversing the Pachwara Pass there 

 is a range of low hills nearly three miles long. This range is formed of 

 rocks which must, I think, be referred to the Dubrajpur group, and will, 

 therefore, be described under that head further on. 



Leaving the Pachwara Pass and proceeding northwards for a distance 



of fifteen miles, we find sedimentary rocks cropping out from underneath 



the trap, all of which appear to belong to the Dubrajpur group. Barakars 



are not met with again until the valley of the 

 Chuperbhita Pass. /-«*•• •
