and Damuda formations of the Tawa valley. It extends to the 

 west for about 30 miles from Baitool^ the crystalline rocks being- 

 exposed irregularly in the valleys, whilst the hills are capped by 

 sandstone and trap. Its eastern extension has not yet been surveyed. 



A large portion of this area consists of highly granitoid rock; indeed 

 in a portion of it the existence of granite is mentioned by Mr. J. G. 

 Medlicott in his report and indicated on his map. But he remarks on 

 the indistinctness of the boundaries and on the difficulty of separatino- 

 the granitoid from the gneissoid varieties. 



The examination of the small tract around Baitool which is com- 

 prised in the map, was so hurried that the general direction of the folia- 

 tion can only be approximately inferred. It appeared to be nearly the 

 same as in the Nerbudda valley to the north, about east-north-east to 

 west-south-west. 



About 30 miles south-south-east of Baitool at the south base of the

Salbuldee. The beds are only traced for a mile or two and appear not to 



exceed a few hundred feet in breadth. 



2. Hurda and Nimawur metamorphic tract. 



This also is of no great extent. To the east it is covered by 

 the gravels and clays of the Nerbudda valley, to the north and 

 south by trap, to the west by the Vindhyans, A considerable por- 

 tion of the intervening area even is occupied by the series next to be 

 described. 



A large proportion of the rocks are, here also, highly granitoid. The 

 general strike is east-north-east — west-south-west, and the dip in general 

 nearly vertical.
