Entering this mountain glen behind the village of Khurree (Khurri) 

 Tertiary sandstones : Banda the usual lower purplish and gray tertiary 

 XeT r m co^tL^^conform- sandstones form open undulations, and in one spot 

 able, but peculiar. a curvature in these allows the nummulitic lime- 



stone to be seen, taking the ground in all directions. Somewhat within 

 the glen a continuation of this limestone (a) appears as if faulted on its 

 northern side, a small surface of the limestone being exposed in the 

 centre of an anticlinal curve. At the contact the limestone is lumpy 

 with interstices filled by purplish-gray clay similar to that of the ad- 

 jacent bed above; this is succeeded by gravelly layers containing con- 

 cretions and pebbles of bluish limestone and of sandstones similar to 

 those in the immediate vicinity, the sandstone and limestone beds being 

 quite parallel and conformable. 



For two or three hundred yards up the stream, the ordinary gray 

 sandstones and purple clays of the lower tertiary sandstone are much 

 crushed and contorted, and then the northern nummulitic rim of the 

 ellipsoid [b) is reached. This limestone is of the hard alveolina kind, 

 and is inverted, dipping south at 80°, the gray tertiary sandstone coming 

 next above (but here underlying) it, having been apparently crushed 

 along its surface in such a way that angular portions of the limestone 

 were dragged from their places and gray sandstone forced into these 

 cavities to a depth from the surface of the limestone which in one place 

 measured 10 feet. The fractures of the limestone are all angular, and
