to observe that this proximity seems to have exercised no influence upon 

 the state of disturbance of the youngest rocks, which is if anything less 

 here than elsewhere : I am not prepared to offer any positive explan- 

 ation of the coincidence. The diminished prominence of the Sivalik 

 range seems to be in some measure due to change in composition : the 

 sandstones are more earthy, and much softer than to the east of the 

 Markunda, and the alternations of clay continue to be more frequent. It 

 is only of the Sivaliks of this region that we can say that their strata 

 are undistinguishable from those of the plains. The passage of the 

 Sutlej through the range at Roopur is a wide alluvial valley. In two 

 sections that I made of the range beyond, — one outside Una, and the 

 other near Hoshiarpur — the flat anticlinal flexure is well denned, and 

 still of the normal type, with the lesser slope towards the dun. This 

 ridge, which is more or less continuous with the Sivalik range of Dehra, 

 does not extend beyond the Beas ; the second zone there becomes the 

 outermost.
