Od the Makrach side, this spur is bold aud steep^ huviug- more the 



character of an escarpment than the'other side. 

 Makrach side of spur. 



The rocks, too, dip to south-by-east at hig-her 



angles than on the outer slopes. The purple sandstone [shows a 

 thickness of some three hundred feet_, but the shaly group No. 3 is in- 

 significant, being apparently united with the light- coloured sandy beds 

 of No. 4. A thin red band or two occur near the base of the " olive 

 group/' overlying the possible representative of the group No. 5, this 

 being near the place where it commences. The whole sandstone 

 series below these red bands is about three hundred to four hundred 

 feet thick, and at the eastern end of the Makrach salt-marl valley the 

 beds are bent into an anticlinal curve, which on its south-eastern side 

 passes below the Dandot plateau, and to the north-east under the long 



limestone ridge from Choya-Saidan-Shah, which

forms the inclined southern side of Gamthala glen. 



Near the mouth of this glen just beneath the nummulitic lime- 

 stone, there is strong development of the coaly

inches thick. A good deal of slipping m the 



vicinity obscures this place, and the dip is very high to the north, so that 



the shales appear unusually thick, the outcrop being 130 yards wide 



with a dip of 70°. The shales include some white, lumpj^, sandy, and 



gypseous beds, and the lower part contains plant fragments. Underneath 



the coal-shales are soft white sandstones and red shales overlying a thick 



mass of the usual metamorphic-pebble conglomerate and sandstones 



of the "olive group^^ with which these red beds are provisionally placed. 



The whole group is thick, but much concealed. From beneath these 



beds, the red, rippled, flaggy and shaly rocks, with micaceous layers and 



Annelide tracks, representing the " salt pseudomorph zone,^' make their 



apppearance ; and in the undulating light-coloured semi-calcareous beds 



o£ the " magnesian group " the white oolitic bands with a thickness of 



twenty feet (the same as on the turnpike road near Khewra) were 



again observed.
