Chap. II.] the Himalayan sekies. 4>5 



In the hills north of Koad there is a note-worthy example of variability in the rock which 



I suppose to represent the upper Krol limestone. In the valley 



the Blini group is well exposed ; on ascending to Jerrog dark 



slates and grits have a steady northerly underlie ; at Jerrog there is a band of thin compact 



limestone, over this come more shaly slates, with fine, crumbling, earthy, calcareous beds. 



The dip gradually diminishes to a low angle. So far we have a very fair representation of 



the Infra-Krol and lower Krol strata, except in the absence of the Krol sandstone, in its 



normal position. Conformably resting on these beds, and with the same low northerly dip, we 



find, forming Kerloe peak, some six or eight hundred feet of 

 Kerloe Peak, . .,,"'-, 



thick clear sandstones, with occasional shaly partings, and at the 



summit of the peak just a remnant of hard, cherty, sandy limestone, — a typical upper Krol 

 rock. Besides the evidence of this hard, sandy limestone, I found, in the extension of the 

 same band to the eastward, that in many cases beds of sandy limestone occur through the 

 more purely arenaceous strata, so that it seemed to me that this band was not to be considered 

 so much a newly intercalated member of the series as a local modification, and a true equiva- 

 lent of the upper Krol limestone. Far to the west, about the Sutlej, I shall have to call atten- 

 tion to a similar fact, in what I suppose to be the same sec of beds. Immediately north 

 of Kerloe peak there occurs a line of great contortion. The sandstones turn up in a 

 uniclinal curve to nearly vertical, and are then folded over on themselves again by a 

 sharp anticlinal. Along the line of gaps on the southern spurs of Guma ridge, to the 



north of this arenaceous band, beds of black and calcined shalv

slates are again brought in, dipping northward under the 



limestone which forms the Guma ridge. 



In descending into the valley of the Neweli from the west, one passes downwards over a 



thick section of slates and grits. The valley is denuded alone: a

flat anticlinal, the axis of which slopes to the north of west ; the 



strata on the north incline more to the north-west, and those on south to the west ; about 

 Batewli there is a considerable thickness of black, ferruginous, and flinty slates, and they are 

 succeeded by a great thickness of hard, clear, finely granular limestone, sometimes very com- 

 pact. Below it, under Othri, there is a conglomeritic band among the slates ; it may repre- 

 sent the Blini group. This great limestone in the Neweli is no doubt the same as that seen 

 more to the north in the Suinj. In both sections, as so often elsewhere, we are confronted by 

 the difficulty of the apparent intercalation of our supposed uppermost rocks with strata, which 

 in less troubled sections seem to underlie them. A few weeks' work on the hills about the 

 head-waters of the Neweli, the Bungal, and the Suinj ought to throw much light on this 

 important question, as well as on that of the granitoid rocks on the summit of the Chor, and 

 with which it is connected. I hope that the few indications I have given will at least show 

 what are the difficulties to be encountered. 



Whatever links in geological structure we may establish between the 



Chor mountain and the Himalayan range in gene-

ral (and these links are not few), this mountain 



has a very decided individuality of its own, of which I am at a loss to give
