bedded, and always micaceous. The Eaniganj shales arc well laminated ; 

 and the sandstones are usually compact and brittle on account of the 

 lime contained in them. 



The stamp-rocks are the red clays found towards the middle and 

 in the upper part of the group. The best exposure of them is in the 

 neighbourhood of Jurwa^ to the north of, and in the bed of the Dhur- 

 durwa river. The following section made by Mr. Ball and myself 

 in that stream, will show the composition of the lower Panchets, and 

 exhibit the proportion that the green and red clays bear to the other 

 rocks of the group. The entire course of the river was plotted, from the 

 Kodwa and Hurdeea ghat to the point where a beautiful water-fall occurs, 

 as the stream issues from the hill, and commences its tranquil flow 

 through the plain.
