from afar, and during the rains they change the flooded water of the 

 Milach stream (Hurroh R. head-waters) to a reddish chocolate colour. 

 The presence of these outliers of higher tertiary rocks in this valley, 

 whilst there is no trace of them along the strike on the Moorchpoori 

 ridge, is a peculiarity which requires accounting for. The exposure 

 of the rocks in the bed of the stream is rather peculiar. Steep 

 crumbling slopes of them, densely covered with forest on the south 

 side, and bare on the north, lie in an apparent anticlinal — see fig. 21. 



Milach. 



Fig. 21. 



The lowest part of the apparent anticlinal is composed of pur^ 

 plish red splintery shales with purple and grey sandstone courses, a. 

 Higher up in the section the sandstone dies out and nothing but 

 purplish shales remain, b. Above this again in contact with the 

 Nummuiitic rocks there is a layer of gypsum and dolomite, the former 

 often filling up the interstices of the latter, c. The Nummuiitic rocks 

 appear above, first as shales and nodular limestone, d. Wynne in 

 one of his papers 1 refers to these red rocks as though he admitted 

 the possibility of their belonging to the Infra-Trias, although he 

 thought it more probable that they belonged to the Kuldana beds. 

 The latter view seems to me to be the only possible interpretation. 

 No difference is observable between them and other sections in the 

 Kuldana series near Murree, whilst the dark sandstones associated 

 with the purple shales are very typical Tertiary sandstones, a rock
