the top they are cut off by (?) the Dulchipore sandstone and the Kymore 

 rocks which lap over on the Semri sandstone — these three are so very 

 much alike that it is often, in such a position, difficult to distinguish them. 

 The parallelism of all the beds is so very approximate that without 

 uncovering and washing the section it would be impossible to say 

 whether the Kymore beds actually lie on the edges of the shales or 

 whether these become gradually extinct, but there is plenty of supporting 

 evidence for the latter case. In the gorge which the Semri has cut 

 through the ridge of Semri sandstone it is well seen that the slope of 

 these beds is not the result of an upheaval, the great lenticular masses 

 of sandstone do not lie on the surface of junction with the Bijawur rocks; 

 they are heaped up against it, and are now to all appearance in the 

 precise position in which they were accumulated: the Bijawurs presented 

 a barrier to their extension as they afterwards did to that of the shales and 

 limestones. More to the West in the river under Sanodo these thin beds 

 are more distictly cut off by a group belonging to their own formation. 

 They show for a few feet in the gorge, but the Dulchipore sandstone 

 and conglomerate stretch on to the Semri sandstone on the back of the 

 hill over Shahgurh. This group becomes to a certain extent the represen- 

 tative of the Semri shales ; away from their north boundary they become 

 thin and earthy and show the same troubled stratification as do the shales 

 to the East. 



The question — when these rocks were so contorted? is essentially 



connected with the right representation of the sec-

tion : however, I can only answer it conditionally. 

 I may here state that I did not see a single case of decided unconforma- 

 bility upon these beds, either of the superior groups of the Semri series 

 or of the Kymore rocks. If this negative case could be made universal 

 the question would be answered, on the ground that this contortion could 

 not have existed before the deposition of a superior group, without such 

 unconformability resulting.
