silicious laminse which form another well-marked but lower ridsfe, on 

 which is built the Durga lying- north-east of Gogi. The lower blue 

 limestones appear below the silicious beds. 



At Gogi the lower beds are vertical, but the dip decreases as they 

 are followed eastward, while the cherty band of limestone seems to 

 have thickened as well as the overlying quartzites, the former giving 

 rise to the Durga ridge, the latter to the Hottapatti ridge above named ; 

 and, in each of these, the beds of which they are respectively made up 

 must have a thickness of at least 200 feet. 



Eastward of the Hottapatti ridge the limestone bands are traceable 

 with a steadily decreasing dip to the neighbourhood of Bidderani, where 

 the lower red shales with their underlying dirty green and brown 

 associates show below the limestones. 



Nowhere along the Gogi boundary line were the shales or basement 

 sandstones seen. In all probability they were not

shales not present or developed there : if they were, they must be so

thm as to be very easily obscured, or else they 



must have been crushed or faulted out of sight. 



The quartzites of the Hottapatti ridge appear to be only a local 

 intercalation, though one of great importance and interest ; they were 

 not met with elsewhere. 



Mr. King thinks the cherty silicious beds forming the Durga 

 ridge may represent the similar beds on the hill west of the Shahabad 

 railway station. 



Although these different bands of limestone, quartzite or shaje 

 appear to be quite conformable, Mr. King thinks it is possible that the 

 Hottapatti quartzites may represent a break between the compact blue 

 limestone (and its underlying shales, &c.) and the upper flaggy and 

 more earthy limestones with their overlying red shales.
