150 NERBUDDA DISTRICT. 



surface (d } e, and/, of our list, page 148.) The beds have been consi- 

 derably, disturbed, and the massive thick sandstones of the Mahadeva 



group (see below) rest unconformably on them. 



The Damuda beds are found only at the bottom of the Morun glen, 



and only a very small patch of them can be seen, 

 Area very small here . ' - . 



both sides or the glen are tormed ot Mahadeva 



sandstone (as stated above) and on the west these are almost immediately 



covered up by Trap. 



Proceeding hence towards the East, the Damuda and Talcheer beds 



will be seen to occupy a large area in the Valley 

 Tawa Valley. 



ot the lawa. (bee map.) 



The Tawa is a considerable stream confluent with the Nerbudda a 

 little above Hosungabad, and which issues from the hills on the south 

 side of the valley through a gorge, at the entrance of which the old fort 

 of Bagra stands. 



It drains a very large area within the range to the south, its nu- 

 merous tributaries reach many miles to the east and west among the 

 hills, and itself flows across a wide plain surrounded almost on all sides 

 by the high ground. All the low ground of this plain, and of many of 

 the glens which open into it, is occupied by the rocks under considera- 

 tion, and many fine sections of them are exposed. 



The green muds and Boulder-bed (a, b, c,) are occasionally met with 



in almost every part of this area, but they are far 

 Bocks exposed, 



more largely developed towards the south of it 



and it is there that they may be best studied. 



Such impurities, if equally abundant throughout, would render the mineral commercially 

 useless; a circumstance the more to be regretted as no coal is known to exist to the west 

 of this place, and the position of the out-crop gives it many advantages over Sonadi, which 

 is, next to this, the most westerly coal of the district. From that place a quantity of coal 

 was taken to Bombay some years since under the auspices of Sir R. Hamilton. Situated on 

 the level of the Nerbudda Valley, and many miles to the west of any other known out- 

 crop, this locality will doubtless receive a trial, whenever a demand for the mineral exists 

 within a distance sufficiently short to admit of its being worked to a profit, after cost of 

 transport has been paid.
