PHYSICAL GEOGRAPHY. 27 



the broad valley traversed by the so-called " hill road" from Karachi to 



Sehwan. The highest hills of the Laid range are near the northern 



extremity, but none attain an elevation much exceeding 1,500 feet above 



the sea. West of Manjhand, the eastern portion of the range is 



traversed by a small stream called Mohan (Runneewaree and Sanwari of 



the map), and on this stream is situated a' large fortified enclosure known 



as Ranikot (Rani-jo-kot), or Mohan Kot. 



West of the valley traversed by the hill road from Karachi to Sehwan 



and south of the Manchhar lake there is a rather 

 Badhra range. 



high ridge of limestone, nearly 80 miles long from 



north to south, and joining the Khirthar range close to the southern 



extremity of the latter. This range is called Badhra (Budhra) on the 



survey maps, and consists of a great anticlinal roll of nummulitic 



limestone. To the west of this, again, is a smaller 

 Bhit range. 



ridge of similar formation known as the Bhit 



range, likewise joined to the Khirthar on the south, but only about 20 

 miles in length and 2,790 feet in elevation where highest. A low name- 

 less ridge, chiefly composed of miocene rocks, runs from north-west 

 to south-east, parallel with the south-western shore of the Manchhar 

 lake. 



All the ranges hitherto noticed are on the eastern side of the 

 Country east of Laki Khirthar range, the Laki range alone extending 

 range ' to the southward beyond the termination of the 



Khirthar. East of the Laki range there are no hills of any eleva- 

 tion, although there is a considerable tract of broken hilly country near 

 Kotri, and extending thence northward to Man j hand and southward to 

 Jhirak and Tatta. The Khirthar terminates to the southward close 

 to a small police post called Karchat, near the banks of the Baran 

 river. South of the Baran, a comparatively low ridge of nummulitic 

 limestone runs north and south for about 20 miles, terminating near 

 Bhule Khan's Thana. The next ridge to the 



Dunobar ridge. 



westward is known as Dumbar, and is of no great 



elevation or length ; it runs for about 15 miles north and south, west
