same. At Keraha, south-east of Rewah, they are contorted 

 and rolling on a small scale, made up of thin beds of sandstone with 

 short lenticular layers of greenish- white and dark red aluminous shale. 

 From the talus-covered nature of the escarpment, sections are rarely 

 foimd of the upper beds. At Dibhur ghat, however, one is obtainable, 

 showing below a considerable thickness of greenish and greenish- 

 brown shales with layers of impure sandstone ; these pass into a 

 red earthy rock, sometimes hard and breaking with a conchoidal 

 fracture and sharp edges, in beds up to 2 or 3 inches, but shattered 

 by jointing in every direction, similar to (b) in the following 

 section. Other parts are softer and in thinner beds. In this 

 part of the sub-division occurs a large amount of greenish-white 

 and red aluminous shale. The intercalated beds of sandstone foimd 

 below are absent higher up. The top beds and their junction with the 

 upper B-ewahs may be well observed at the falls of the Goorma nuddee^ 



south of Burokxir Khas : —

Resting immediately on this are the massive beds of the upper 

 Rewah sandstone, a good 400 feet. At the foot of two or three other 

 water-falls similar sections of the junction are observable.
