There are several varieties of rocks in the country which would

nummulitic limestone would probably take the first 

 place, and as there is considerable variety in the texture of its beds, it 

 may be supposed that ordinary requirements would readily be met. 



The harder bands of the gray and purplish slightly calcareous sand- 

 stone of the lower tertiary sandstone group are elsewhere very generally 

 used as building stone, and would doubtless be found equally useful 

 here. Mixed with the lighter coloured limestones they would produce 

 a handsome variety of tints for ornamental ' ashlar 3 work, and among 

 the most thinly stratified layers serviceable flagstones could probably

By whom it was discovered is unknown, but its being brought to 

 notice is due to a native officer of Kohat station and to Major MacLean

 of the village of Dand, north-west of Shakkardarra. He had great 

 difficulty in finding anybody willing to show him the spot, and though, 

 when he reached it, without any digging implements, he succeeded in 

 extracting some baskets -full of the coal. 



He could give no information as to the thickness of the seam, and 

 could only say it occurred in a sandstone cliff.
