THE LAKI RANGE, ETC. 131 



beds occupy all the low ground between the Tiyun range and the hills o£ 

 Khirthar limestone, east of the fault forming the eastern boundary 

 of the older beds. The lower beds of the cretaceous sandstone group are 

 still concealed. About 2 miles south of Jakhmari the Ranikot beds 

 come in beneath the Khirthar limestone east of the fault, and continue 

 for about 2 miles farther to the southward, being chiefly seen to crop 

 out in the scarp, east of the fault, underneath the Khirthar limestone. 

 The Ranikot beds disappear again beneath the Khirthar limestone close 

 to a place called Khirdhai. West of their exposure, the olive shales 

 only are met with for some distance, the dark cretaceous sandstones being 

 concealed ; but the latter crop out again south of Khirdhai, and thence 

 to the southward form a well marked ridge for many miles, culminating 

 in the two hills of Barrah. The higher of these two peaks, that to the 

 southward, rises to a height of 1,200 feet above the eastern base of the 

 hills, and 1,100 feet above the valley through which the fault runs 

 east of the first range. 



The dark-coloured sandstone ridge here becomes conspicuous from 



Cretaceous sandstone tne P lain to tlie eastward, for the rounded hills of 

 hlllSt sandstone tower above the crags of grey Khirthar 



limestone to the east of the faulted anticlinal, and are relieved against the 

 pale-coloured scarp, also composed of Khirthar limestone, to the westward 

 of the anticlinal and on the eastern side of the main range. The most 

 conspicuous dark-coloured hills seen are those of Barrah to the north, 

 Bor 3 or 4 miles to the southward of Barrah, and Gadha or Hus, 

 2 miles farther south, and 9 miles north of Ranikot. Unfortunately 

 all these most interesting sections are difficult of access, there being no 

 roads or villages in the neighbourhood, and the country for many miles 

 from the hills being a waterless desert, except after rain. 



The section at Barrah hill (Plate V, fig. 2) is the most interest- 

 ing of all, as the lowest beds known to occur in 



Section at Barrah hill. 



Sind are seen here alone, and the whole series is 



well exposed. A very small stream issues from the range, and cuts its 



way through the eastern ridge of Khirthar limestone : farther up, the same
