The red marl, in the glen opening on the road from the west, just 



where the ascent commences, alternates (unless the 

 Alternation of lower . i i i v \ 



purple sandstone and salt appearance IS produced bj shps) two or three 



^^^' ■ times with dark purple bands of exactly the same 



character as the lower part of group No. 2. The rest of the groups 



succeed in their regular order, but on the south side o£ this glen a mass 



of the carboniferous limestone has slipped, or is faulted, so as to conceal 



everything else, and to be in contact with the red-marl group. About a 



mile and a quarter northwards of the pass are the hamlet and serai of 



Katwahi, situated among hills of carboniferous and 



nummulitic limestone. Some of the ground about 



the village is either flat or cultivated, so as to cause difficulty in defining 



the boundary lines, one hill being of one limestone, and another of a 



different kind, with here and there small patches of red beds, belonging to 



the group No. 5 below the carboniferous, appearing in an obscure manner. 



Where the road to Sakesar ascends a hill from the immediate vicinity 

 of the serai, some coaly gypseous shales which are 

 exposed in the sides of the road-cuttiug, belong, 

 most probably, to the nummulitic limestone which forms the adjacent 

 hill. The two higher hills, one to the southward and the other east of the 

 serai, are both of nummulitic limestone also ; but between their beds and 

 the underlying carboniferous rocks, some greenish shales and calcareous 



beds, containing a few Ceratites, make their ap- 



Ceratite beds. , , „ , , t ; , ; 



pearance ; these are some oi the earliest traces to 

 the eastward of a new (triassic) group which further west always accom- 

 panies the carboniferous rocks.
