rocks are hidden by an obscurity. They are inserted in the section 

 from evidence close by. 



Nature has provided two parallel and similar lines of section to 

 Parallel sections to the tne one j ust described. The first of these is a 

 north-east. transverse gorge passing between the Chuj- 



jian and Sribang hills, and the second a transverse gorge passing 

 between the Sribang and the Doobran hills. That to the north-east 

 of Doobran has already been mentioned. The intervening hills are 

 great heavily-built masses, so evidently but parts of one uniform ridge 

 trending towards Balkooh and Bulkot, that the dividing gorges may 

 easily be overlooked. This ridge rises from the Hurroh river to 

 about 3,000 feet above it, in great convex slopes steepening down- 

 wards. 



The first of these transverse gorges begins near Chujjiyan village 

 or Chothai, and is a scarcely noticeable stream at first, draining a flat 

 cultivated open valley in the upper Nummulitic shales and concre- 

 tionary limestones. But about half a mile below Chothai it suddenly 

 leaps over a nearly vertically dipping slab of limestone in a fall of 

 about 150 feet. The section then proceeds down a gorge or chasm 

 almost as shut-in as that of Riala. From Chothai village the section 

 is as follows :— 



(1) Nummulitic limestones and shales. 



(2) Grey limestone, well-bedded .... ioo feet. 



(Waterfall.) 



(3) Dark-grey sandy limestone . . . 50 „ 



(4) Dark and pale grey limestone, sometimes rather 



sandy 350—400 „ 



(5) Dark-grey sandy limestone as (3) . . 50 „ 



(6) Dark and pale limestone as (4) ... 200 „ 



(7) Cretaceous. 



(8) Jurassic. 



(9) Triassic. 



(10) Repetition of (3) and (4). 



In the above section, somewhere about the junction between (4) 

 and (5), fragments of the Jura-Cretaceous rocks were found, so there
