COUNTRY BETWEEN THE KOTAH AND PATLI DUNS. 51 



level of the ground. Near their origin the streams cut through con- 

 glomerates dipping 20 N.N.E. This lowers a little to 15 or 

 io° in the sand-rock, which, as before, sets in gradually by inter- 

 stratification with the conglomerate. Towards the plains the several 

 minor streams unite into one gorge, where the dip is about 25 or 30 

 in the same general direction. There is also an accompanying 

 hardening of the beds southwards, though the rock has still no title 

 to be called a sandstone. 



All the features of the sand-rock stage are now laid bare in very 

 beautiful and perfect sections, illustrating the sequence and variations 

 described under the heading of Petrology (Chapter III). Where the 

 streams empty themselves into the plains, there is usually a well-marked 

 vibration of the direction of dip on each side of the normal direction, 

 as alluded to in the last paragraph. There is also no southerly dip 

 of the strata at the margin of the hills : no preservation of the south 

 portion of the anticlinal or middle limb of a sigmaflexure. 



The great uniformity in the lie of the rocks in this part is reflected in 

 the surface features. Standing on the conglomerate ridge between Bar- 

 s6ti and Laldhdng, one looks down southwards into the country drained 

 by the afore-mentioned streams, and the eye can grasp nothing except a 

 broken and disturbed sea of jungle. The streams are too much shut 

 in and too winding to be made out from this position. There are no 

 lofty peaks or marked ridges to catch the eye : the whole is so alike, 

 that it is as impossible to individualise any hill as it is to distinguish 

 each wave in a wide ocean. Only, when looking along the strike of 

 the more lofty portion near the plains, can one see the regular dip of 

 the strata N.N.E., a structure which relieves the monotonous maze of 

 hillocks to a certain extent. Northwards from the conglomerate 

 water-shed one looks down a long series of side-spurs of the con- 

 glomerate, expanding into triangular chaors as they near the Rdm- 

 ganga R. Turning our gaze more in the direction of the Pitli dun, 

 we may see these chaors approaching one another and levelling out 

 more and more to form its southern slopes. 



Before going on to describe this dun, I must give a few details
