AREA SOUTH OF THE SAFED KOH. 99 



The eocene rocks are well seen on the road from Koh£t to 



Kai, and have already been described by 



Eocene. J 



Between Kohat and Mr. Wynne. 1 To his description I have nothing 

 to add except that, in the alluvial plain about | 

 mile west of Hangu dak bungalow, part of a large mammalian femur 

 was found by Major O'Sullivan, R.E., A.Q.M.G., T.E.F. It was not 

 perceptibly waterworn, and could not, therefore, have travelled any 

 great distance ; this would point to the existence, not far from Hangu, 

 of a bed containing mammalian fossils. 



Between Kai and Shinawari (Lat. 33°3i' N., Long. 70°5o' E.) the 

 eocene beds are composed of sandstones inter- 

 bedded with light-coloured and greenish shales. 

 The sandstone, which is well seen on the small 

 hill on which the village of Kai stands, varies in colour from a pale 

 buff to a dark, highly ferruginous rock, but in almost every case its 

 weathered surface is black : a characteristic also noticed by Mr. 

 Smith in the eocene sandstone of the Tochi Valley. 2 At about i£ mile 

 south-east of Shinawari it is underlain by olive-coloured and reddish- 

 brown shales containing, locally, thin bands of 

 shale - highly altered limestone, which, on the southern 



flanks of the Sama*na range, are in turn under- 

 lain by a hard, compact, grey limestone, of either lowest tertiary 

 or uppermost cretaceous age. The above rocks form the southern 

 flank of the Sam£na range and dip at high angles to the south. 



Tertiary rocks are not seen again north of the Sama*na range till 

 the Maidan Valley of Tirah is reached : here

they occur in a narrow band not more than 700 

 feet wide. They are best seen on the saddle between Maiden and 

 Warin, where they form the low (t Kotal " (Tseri Kand^o) separating 

 the two valleys. Their strike is almost due E.-W., and they
