WYNNE : GEOLOGY OP THE SALT RANGE IN THE PUNJAB. 



the carboniferous limestone wbicli near this runs out upon the plaiii^ 

 but the upper part may be reached by ascending over some " red salt- 

 marl/^ up a slope of the "speckled sandstone/"" No. 5 (the intervening 

 " purple sandstone " being absent) , edged by cliffs of the carboniferous 

 beds which dip towards the valley, and support the shaly and flaggy 

 beds of the Ceratite-bearing trias. The latter being passed, the 

 variegated and calcareous beds of the Jurassic formation are reached, 

 the section, so far, being as follows, according to my own observa- 

 tions and some notes of Dr. Waagren^s made in this neighbourhood : —

Further up the ravine leads through a natural tunnel made by the 

 stream throuo-h a mass of the carboniferous limestone, introduced 

 by faults or slips. Beyond it the Jurassic rocks are again reached, 

 occupying one side of the valley, while high up on the other is the
