DAMUDA SERIES : BARAKAES. 53 



It was in this jungle that I found some stone implements, which 

 Implements. are now in the Geological Survey museum. 



The felspathic sandstone noticed above forms the bed of theriver 

 for a long way, as its strike coincides with the course taken by the 

 stream. Coaly shale is seen in one of the bends injured by trap. The 

 next bend of the river again brings in the felspathic sandstone. 



After a long interval the coaly shale re-appears, not injured by 

 trap. It is four feet six inches thick. It possesses scarcely any dip. The 

 felspathic sandstone holds steadily on down the stream, worn into hollows 

 of every conceivable shape; pot holes meet one at every step. The 

 generality of them, however, contain no pebbles, and are evidently the 

 result of mere water action. 



A large seam occurs nearly west of Ghatotand, or rather west of 

 the mouth of the Beessoor-gurha, measuring 22 feet in thickness. 

 The direction of dip veers about, and from this point to the confluence 

 of the Hoharoo and Bokaro is never steady. The seam itself dips 

 in one portion east and then becomes east-south-east. Above the seam the 

 dip remains steady east-south-east for about half a mile. The angle of 

 inclination varies in amount. It increases in the beds above the 22 feet 

 seam, but when we get to another large seam it decreases again and 

 becomes nearly horizontal. This latter seam is a mixture of carbonaceous 

 shale and coal, but portions of it are worth extracting. The directions 

 of the dip are shown in the map. 



The carbonaceous shale group crops out in the river south of this 

 last seam. 



Some more seams are seen in the Bokaro, east and west of Suroo- 

 bera. The beds in the Bokaro are higher than those in the Hoharoo. 

 I will, as there are only a few feet of Barakars exposed in the Hoharoo 

 near Bongahara, unite the two sections.
