HILLY RANGES AND THEIR NEIGHBOURHOOD FROM BAHADUR KHEL, &C. 165 



cides with a nearly east and west ravine among the tertiary sandstones 

 to the northward, exposing 1 a portion of the underlying series, and yet 

 another, parallel and passing northwards of a part of this, is shown to 

 occur by a strong rib of gypsum appearing again among the tertiary 

 sandstones. These faults and the low cliff-like outcrops of the sand- 

 stone series about here give many opportunities of observing the dis- 

 appearance of the whole of the nummulitic group, a thin representative 

 of which is occasionally seen, and even this sometimes is entirely absent.
