ceous slaty shales. The strings of anthracite which occur in these slaty 

 shales at Dundelee were the object of my visit. Both the clays and the 

 slates are greatly contorted ; but, as well as one could judge, they 

 observe approximate, parallelism in contortion. Fig. 10 represents roughly

the section at Dundelee. I was so struck by the analogy of the section 

 with what I had seen in the Subathu region, that in spite of appear- 

 ances, and, as I had not time to examine the ground more closely, I 

 adopted the opinion that the carbonaceous shales were originally over- 

 laid by the limestone band, which I took to represent the Krol group ; 

 the identification is of the same vague kind as that made for the rocks 

 in the valleys of the Sutlej and the Beas {vide Chapter 2) ; I could find no 

 fossils in the clear limestones of the ridge. It should be noticed that the 

 steady general strike of the rocks at Dundelee is remarkably constant 

 towards the direction of Himalayan elevation. 



The tract of mountains intervening between the Poonch and Murree, 

 Subathu group in which is the great sanitarium of the Upper 

 zaia " Punjab, is occupied by the Sub-Himalayan series. 



But in the region of the Jhelum valley a total change takes place in the 

 system of disturbance. The well defined ridges about Murree have a 

 steady north-east south-west strike, which is also that of the strata. 

 So far, however, no new rock is introduced ; Murree is built upon a ridge 

 of purple clays and hard sandstones ; the ridge to the north-west of it, 

 a continuation of a lofty mountain-mass of Mochipoora, is of clear blue 

 limestone. In the intervening valley, we find brown and variegated
