2G SUB-HIMALAYAN ROCKS OF N. W. INDIA. [CHAP. II, 



The evidence of this section is, I think, conclusive as to the normal 

 position of the Krol group of strata, and warrants the supposition that 

 the actual order of superposition is the original one. The Krol group, 

 therefore, at least provisionally, is to be considered as the most recent 

 formation of all the series of strata of the lower rocks described in the 

 present chapter, the next youngest rocks being the nummulitic beds 

 of Subathu; but a possible modification of this view will be sug- 

 gested farther on. In attempting to sketch the portion of the section 

 that has been denuded from over the present valley of the Blini, the first 

 idea suggested is to suppose it a great anticlinal bend. But such could 

 scarcely have been the case ; the hill of Kanoge, as I have already pointed 

 out, is at a short distance off in a position corresponding to about the 

 centre of this Blini valley, and on it we find .the limestone at the 

 same height as on the Krol and the Boj, and forming again a broken 

 synclinal. 



It may be noticed that the terms I have applied in describing 



the rocks of this group indicate a degree of in- 

 Degree of induration. • 



duration inferior to that of the underlying strata. 



The term slaty is here scarcely applicable. It may be doubtful how far 

 this difference in induration is due to the more purely argillaceous 

 composition of the earthy beds of this upper group, or to their 

 greater thickness of bedding, or to their being intercalated among 

 hard limestones, where all have apparently undergone the same amount 

 of disturbance. It is a fact, however, not to be lost sight of. Elsewhere, 

 beds that I identify with those of the middle Krol are considerably 

 more hardened, there being also in such cases independent evidence of 

 the rocks having undergone greater compression. 



In the mode of disturbance of the strata these two remarkable moun- 

 tains exhibit, typically, a feature that is not so strongly marked else- 

 where, if indeed it be not peculiar to this portion of these hills. , It 

 is a very common fact throughout the external zones of the Lower
