the Nerbudda watershed^ is also included. To the east and north the 



country is comprised in Mr. J. G. Medlicott's map in Vol. II of 



these Memoirs^ which bounds the northern parts of the present area,

Atlas. 



All the southern and western portions of this area are of trap.

being constructed, except one so rough as to be merely an indication. 



The geological lines are therefore only the very roughest approximation. 



The extreme north-east corner of Atlas Sheet"^ No. 54 is in the 



Tawa valley, within Mr. Medlicott^s map. South of this is a belt of 



high ground upon which Baitool stands. To the

north this is composed of metamorphic rocks : to 



the south all is trap. 



The boundary of these rocks from Amla to Sohagpoor and thence 

 westward south of Baitool is natural and not faulted. Its features are 

 well marked, the traps rising in a continuous range, flat topped, as usual, 

 to the south, while the very granitoid metamorphics either occupy a 

 level plain or form isolated hills and short ranges. Upon some of the 

 latter, outliers of trap occur, but they are of no great size. At one 

 spot there is a small patch of conglomerate between the base of the 

 trap and the metamorphics. 



Gneiss, rather less granitoid than further east, but still highly 

 crystalline, forms the hills stretching across to the north of the civil 

 station of Budnoor. Some crystalline limestone was found in them,
