Higher up in the Tawa, trap comes in, and further on still, there is 

 a patch of metamorphic rocks. It is of no great extent. The rock is 

 granitoid. 



Section 3. — Neebudda valley north of the river, from Chand- 

 gurh and sutwas to burwai and the simrol ghat, including 



THE DhAR FOREST. 



Passing westwards from the open alluvial tract of the Nerbudda 

 Characters of Dhar which extends to Hurda and Nimawur a large 

 expanse of wild, almost uninhabited country, is 

 traversed by the river. This tract is still bordered on the north by 

 the scarp of the Malwa plateau, here entirely composed of trap, but 

 instead of the lower country near the river being level, as near 

 Hoshungabad, it is extremely hilly and rocky. A large portion of this 

 region of jungle belongs to the principality of Dhar, and is known as the 

 Dhar forest. 



The river itself traverses Viudhyan sandstone during by far the 



Eocks occurring. ^""^^^^^ ^^""^ ""^ ^^^ ^°^^'® between Chandgurh 



and Burwai ; farther north the peculiar limestones 



and breccias of the Bijawurs prevail, and in some spots metamorphics are 



seen, but they are much less frequently met with than further east, while 



to the west outliers of the cretaceous beds of Bao'h occur. 



In the Nerbudda near Balkaisiv, metamorphic rocks are seen and 



Eocks in Nerbudda ^^^^^ ^^^^^^ *° ^^^ ^est nearly to Nowahatta, 

 below Balkaisir. ^-j^^^q ^ ^^.^^^ ^^^^^ ^f hornstone-breccia crosses the 



stream, striking east-20°-north. Below this, the bed of the river and its 



immediate neighbourhood are principally occupied by overlying trap or by 



masses of conglomerate, which appear to be of comparatively recent date. 



It is not clear whether the band of breccia marks a fault, or 



whether it belongs to the Bijawurs. The latter contain similar beds in 



this neighbourhood.
