 The bedding on the whole is of moderate thickness, but very massive 

 beds are abundant. North of the boundary with the Rewah group the 

 rock is generally rather coarse, of a yellowish-white color, and very 

 commonly stained in patches to a dark brown by iron. The maximum 

 thickness of the Kymores is in the extreme east. Captain Sherwill 

 estimating them at Rotasgurh at 1,300 feet. How much more they 

 origuially were it is impossible to say, since they are there covered by 

 no other beds ; tracing them along the escarpment we find them reduced 

 at Rajgurh to 6 or 700. A magnificent section of them is exposed in 

 the deep narrow gorge through which the central portion of the Adh 

 valley drains to the Sone. Some portions of the bedding are of 

 great massiveness, and the sides of the gorge are in many places pei-pen- 

 dicular walls, caused by a well-marked system of joints running N.- 

 10°- W. Here as in other places those peculiar Httle ridges produced by 

 the filling in of joints or mud-cracks, are exhibited in great perfection. 



All along the Kymore scarp the sandstone dips inwards at 10° or 

 ia°, the inclination seldom exceeding 20°, or being less than 5°. This
