218 WYNNE: TRANS-INDUS SALT REGION, KOHAT DISTjRICT. 



its real thickness. One salt cliff near the guard-house is 60 feet high 

 by itself. The salt is very pure ; indeed, it is said that purer salt could be 

 got here than at any of the other localities in the district. From what 

 is seen the salt appears to contain only a minute proportion of the blue 

 clay which forms the principal foreign ingredient of the salt at the 

 western and other quarries. The uppermost strata only were here inter- 

 laminated with thin bands of black bituminous salt ; some other layers 

 contained small fragments of gypsum. The salt is stratified and shows 

 a dip to the north ; it is either colourless or of a light gray tint. Some 

 that had a reddish look proved to be only superficially coloured by wash- 

 ings from a red marl above. 



The salt outcrops for half a mile along the hill side, and projecting 

 spurs from this are formed of the overlying gypsum from which the 

 presence of more salt within the hill may be inferred. By removing the 

 debris very large quarries could be formed and mining could also be 

 advantageously carried on, as the salt rises 150 feet above the adjacent 

 gorge. 



19. Speena (Spina). — There are here on the north-western side and 

 to the west of a large expansion of gypsum several large open outcrops 

 of salt, some of which discharge brine in considerable quantities as 

 shewn by the thick incrustations of salt in the stream below the hill and 

 to the northward. The salt undulates slightly, and shows strongly 

 round the sides of semicircular hollows. It is of the same character as 

 usual, and much resembles the Nurree (Nam) salt. The western ex- 

 posures occur over the pathway in the pass of Kohneega, on its north- 

 eastern side, but at this place the rocks are all so much broken and dis- 

 turbed that no relations can be discerned among the confused masses. 

 The larger exposures would suit well for workings. 



20. Sirraikhvd. — Salt is seen in two principal places here, both in 

 cliffs, north and north-by-west of the village of the same name, and, as 

 usual, overlaid by gypsum and debris. At the most westerly locality the 

 salt has a face 35 feet high and dips north at 40°. Nearer to the
