Along- the southern base of the hills here from about Luttummer 

 Stony belt at foot of by Soordag and on beyond Goorooza there is a 

 stony belt little inferior in its barrenness to that 

 which is so marked at the foot of the salt range. Its pebbles are formed 

 of the local rocks, and the material, when sections can be seen, is well 

 stratified sandy and stony clay inclined to the southward at angles under 

 30°. Beyond this zone to the southward all the country is a sandy flat 

 traversed by the broad and shallow beds of dry nullahs, sometimes over a 

 mile in width.

 top. This soft zone occurring along the outcrop (as in the salt range)

upon the same drab and reddish clays and coarse sandstones of the upper 



tertiary bed as occur to the north of Soordag. Except where these 



subsided masses project there is little to be seen on account of the thick 



coating of debris with which the slopes are dressed. To the eastward 



(over a place where a village or hamlet . called Sumkilla seems to have 



once existed) the gypsum appears from beneath the red zone with a 



thickness of 50 to 80 feet, much entangled with gray and reddish
