 strata of the interior of the range, where these are not overrun by lime- 

 stone and other debris from the outcrop. 



Just above the road westward from the Serai some of the gypsum

latter, too, may be traced at intervals just below the outcrop of the lime- 

 stone on the crest of the hill, this feature being formed by the hard 

 yellowish Alveolina limestone or marble beds. 



Within a mile to the east of the Serai some small exposures of the 



rock-salt occur among black, earthy gypsum and

 sections are so overrun and concealed that nothing of the structure is 

 observable. Near this place narrow vertical exposures of the nummuli- 

 tic limestone commence, and these continue more or less visible to beyond 

 the village of Drungi Banda at the foot of the ridge where the Teeree 

 (Tiri) river makes a sharp S-like turn in its easterly course.
