sinks into the long flat-topped hills of Saklibara, then trap closes in 



upon the Taptee from both sides, and the river enters the Rajpeepla 

 jungles. 



Section 8. — Nerbudda valley north of the river; from 

 BuRWAi TO Dhurmpooree and Mandoo. 



This area is entirely occupied by rocks belonging to the trappean 



series, and therefore requires no more than a pass- 

 Rocks occurring. . . . 



ing notice. Near the river there is a great accu- 

 mulation of alluvial deposits, and for two or three miles from the banks 

 rocks are very rarely seen. In the river bed, however, trap frequently 

 appears. 



There is every reason to believe that the trap in the valley is of no 

 T a of no ereat great thickness, and that lower formations exist 



thickness. ^^ ^^ moderate depth below the surface. The beds 



of trap are, as nearly as possible, horizontal, and some miles west of 

 Burwai, shallow wells for irrigation pass through the trap into the 

 cretaceous sandstones. 



Another instance of the proximity of the base of the traps may 

 be seen in the occurrence of granite in the bed of 

 budda opposite Mund- the Nerbudda opposite Mundlaisur, a circum- 

 stance noted both by Major Stirling and by 

 Captain Abbott, as previously mentioned. The masses of granite, many of 

 them several feet in diameter, were considered by Major Stirling and 

 Captain Abbott as pinnacles piercing the trap ; they are, however, dis- 

 tinctly isolated and surrounded by trap, often permeated by veins of 

 the latter, and more or less fused, so that on the edges a complete 

 passage takes place from one rock into the other. This is especially well
