which succeed to the Manchhars are vertical, and near the fault have & 

 reversed dip. Some shales belonging to the Khirthar group occur imme- 

 diately beneath the Manchhar. The limestones form a ridge, rising into 

 high pinnacles, at least 200 feet above the bed of a stream traversing the 

 range. 



The sandstones rise immediately west of the Khirthar limestone 

 ridge. About 600 or 700 feet of them, precisely similar to those of 

 Barrah, are exposed in the scarp. About two -thirds of the distance up 

 the face of the hill is a bed of trap about 40 feet thick, apparently inter- 

 stratified with the sandstones. On the top of the sandstones is the usual 

 bed with Ostrea, Turritella, &c. 



The trap may be the same as that seen in the fault at Jakhmari.

looked for at Barrah, and in many places in these 



hills the basalt is so thoroughly decomposed, that it can only be distin- 

 guished from the associated sandstones by close search. It is, therefore, 

 uncertain whether this lower bed of trap extends to a distance like the 

 upper flow. A similar bed, probably the same, was noticed at one spot a 

 few miles north of Ranikot. 



The remaining beds are precisely the same as in the Barrah section.

and the nummulitic limestone only forms a very narrow ridge. Here the 

 whole of the cretaceous beds disappear below the Eanikot group, and for 

 1\ miles, the latter abuts against the Khirthar limestone at the 

 main fault. The trap and olive shales re-appear west of the fault, 

 2 miles farther south, at Kandori, but only for a short distance. Then, 

 after another interval of about 2- miles, the cretaceous beds again crop 

 out at the surface, the sandstones being also exposed, and all continue as 

 far as Ranikot, where they come to an end within the limits of the 

 fortress. They do not extend continuously to the Mohan stream, which 

 traverses Ranikot from west to east, and in which a last appearance of
