Table No. II. 

 Section showing the supposed vertical thickness of the various 

 formations seen in the Salt Eange, estimated at points where they 

 attain a mean development. 



Table No. III. 



This Section represents the Tertiary Miocene formation as seen 

 in the Ehotas gorge, between the plain near Jhelum and the village 

 of Ehotas, and to the N. of this, towards Bukrala on the line of the 

 Peshawur road. 



On entering the gorge, through which the Kuhar stream flows 

 towards the Jhelum, beds of soft grey sandstone, red clays and con- 

 glomerates are seen dipping under the plain in a S. E. direction, at 

 an angle of from 75° to 80°. A succession of these beds follow, the 

 angle of their dip gradually diminishing, until about a mile from the 

 entrance of the gorge, where they present a beautiful anticlinal 

 curve. Beyond this, their dip again increases, and at Ehotas is 75° 

 to the N. W. 



Crossing the bed of the Kuhar Nullah and proceeding along the 

 Peshawur road, beds of alluvium are seen for about a mile. Beyond 

 this, the sandstone strata again appear, dipping at an angle of 75° to 

 the S. E., and may be traced almost uninterruptedly at Eawul Pindee,
