monti and a Nautilus. All the beds of these hills appear to belong to 

 the Khirthar group. 



The upper surface of the limestone on Ganja Hill is worn into 

 Stria due to sand car- conspicuous grooves having a general direction 

 riedbythewind. f e ast-25°-north. These striae are evidently due 



to the scouring action of sand transported by the wind. Similar mark- 

 ings are seen on other hills, but they are not often so distinct. On the 

 limestone hills of Jaisalmir, precisely the same grooves are found. 



CHAPTER VIII.— THE SOUTH-WESTERN PORTION OF THE KARACHI COL. 

 LECTORATE, INCLUDING THE UPPER BARAN VALLEY, WEST OF THE 

 LAKI RANGE, THE HABB VALLEY, AND THE COUNTRY NORTH-EAST 

 AND EAST OF KARACHI AS FAR AS BHULE KHAN'S THANA AND 

 JUNG3HAHI. 1 



The remaining area of south-western Sind is a large tract of country, 

 Arrangement of chap- and some further sub-division is necessary in 

 ter - treating of it. The most convenient plan will be 



beginning, as usual, on the north, to commence in the Baran valley, near 

 Karchat, where the accounts of the area described in the fifth Chapter 

 concluded, and to give such details as deserve notice in the eastern part of 

 the tract first ; and then, re-commencing at the north, to describe the 

 western portion of the area. The first will comprise the Baran valley from 

 the southern extremity of the Khirthar range near Karchat to Bhule 

 Khan's Thana, the country near the road from the last named place to 

 Karachi, and that in the neighbourhood of Jungshahi ; the second sub- 

 division will commence at the head of the Baran valley, and include the 

 portion of that valley west of the southern extremity of the Khirthar 

 range, together with the great tract of Gaj beds north-west of Karachi, 

 the Habb valley, and the neighbourhood of Karachi and Cape Monze. 



1 This chapter is chiefly compiled from Mr. Fedden's reports, except the portions 

 relating to the Habb valley and its neighbourhood, and the country immediately north and 

 west of Karachi.
