The lower portion is obscured by a deep pool of water. 



Near the village of Jordiha there are two outlying patches of trap 

 which rest on the Barakars, proving conclusively that at one time the 

 trap stretched all across the valley, and that to denudation alone is due 

 the fact that the lower rocks are exposed at the present day.

Near Jhupani there is a seam of about 20' of blue and black shales 

 with coaly layers, but no good coal is seen, dip 15°. It is probably 

 identical with the seam in the Gumani near Ludapathur. Further down 

 this stream, too, a very considerable change in the strike enables the 

 seam to appear again. There are indications of attempts having been 

 formerly made to work it. Further south there are several seams of 

 burnable but poor coal, varying in thickness from about 1 to 4 feet ; 

 particulars regarding these will be given in the chapter on Economic 

 Resources. 



The Dhoupahari stream affords a peculiar section, as within its

Talchirs, Barakars, grits and trap ; in the Barakars it exposes a seam 

 of carbonaceous shale, but no coal. 



* This village is not given on the map, but its position is close to the small Talchir 

 inlier.
