148 SUB-HIMALAYAN ROCKS OF N. W. INDIA. [CHAP. TV. 



and there is no warrant for going beyond this, unless indeed to satisfy 



a theory. 



It is curious to notice, about thirty miles off, on the other side of this

Dhaoladhar. The ridge of Puthiar is formed of the lower beds. On its 

 south-west side, between it and the Jarait hills, the conglomerates are 

 vertical, and even inverted along the junction, both rocks having a south- 

 easterly strike. Round the point, towards Burwarneh, the conglomerates 

 are continuous, and stretch on the north-east side nearly to the inner 

 Sub-Himalayan boundary, having a high dip from the Puthiar ridge. I 

 noticed that the conglomerates in this position are remarkable for the 

 local character of their pebbles, sub-angular fragments of the pink 

 limestone of the range close by, with larger blocks of the brownish 

 gray sandstone that intervenes, being the chief ingredients. In the 

 conglomerate on the outside of the ridge the blocks are larger and more 

 rounded ; there is too a considerable admixture of the hard inner rocks. 

 These peculiarities suggest the existence of the Puthiar ridge as a pro- 

 montory in the area of deposition of the younger rocks, and consequently 

 that the feature, as we now see it, is not solely the result of disturbance 

 subsequent to that period. The same inference may be extended to the 

 corresponding feature towards the Sutlej ; it is but a confirmation of the 

 opinion we had to come to in examining the eastern region — that the 

 outer rocks were formed upon an eroded surface of preceding deposits.

find grand sections showing an enormous develop- 

 ment of the conglomerates. The circumstance is manifestly connected 

 with the presence of conditions very similar to those now existing, these 

 conglomerates containing the debris of all the rocks now exposed in the 

 lofty range that rises immediately to the north, — of the trap, of the lime-
