52 WYNNE : TRANS-INDUS EXTENSION OF THE PUNJAB SALT RANGE. 



and variegated sandstones and dark gray pyritous shale below. Some of 

 the sandstones become coarse, gravelly and conglomeratic, with quartz 

 pebbles and ferruginous concretions. 



Beyond the centering of the arch formed by these beds the upper 

 group is similar to its counterpart previously described, and from one 

 gray lumpy limestone band a small sulphur spring issues, the place, as 

 usual, smelling of sulphuretted hydrogen. The stream here for some dis- 

 tance coincides with the strike of the rocks, running in a deep V-like 

 trough, blocked here and there by enormous fallen masses from the cliffs 

 above, but turning again it crosses the beds, giving a section through the 

 supra-jurassic sandstone and the eocene limestone. 



The black band at the base of the pale sandstone group is present : 

 whole layers, some inches thick, of Belemnites occur in its lower part, but 

 only a few Ammonites were found, and these impossible to obtain entire. 



Here, at the place called the Harma Kas, the supra-jurassic sandstone, 

 from such measurement as could be made, is 450 

 feet thick, dipping at 40° to the west. Midway 

 through the gorge cut through this soft, warm yellow- tinted sandstone 

 is a carbonaceous shaly layer 2 feet or so thick, but irregular. Another 

 such black layer occurs higher up, and there is a thin parting of the same 

 a few feet below the nummulitic limestone. 



The upper part of the sandstone is shaly, a few layers of brown sand- 

 stone with coaly strings succeed, then knots of limestone in a gray cal- 

 careous matrix, and this immediately passes up into the usual solid 

 whitish gray nummulitic limestone without the least symptom of the 

 unconformity observed in the Chichali section, or the presence of the 

 basal nummulitic alum shale, unless represented by the gray shaly upper 

 portion of the sandstone itself. 



Where the contact occurs the stream falls over a bluff of the lime- 

 stone, 60 or 70 feet high with lofty walls of this 

 rock on each side, into a deep pool, the fall being 

 called Spin-zdthow from the white colour of the limestone ; here perhaps
