formation met with^ forms tlie hills, and appears here and there in the 

 deeper ravines cut through the alluvium. 



The bed of the Taptee itself was not examined, and the Satpoora 

 hills were only traversed here and there. It was clearly ascertained that 

 no infra-trappean rocks occur in them by carefully examining* the pebbles 

 in the diiFerent streams running from them. Trap may occur in the bed 

 of the Taptee here and there, as it does in the Nerbudda, in the plain 

 near Mundlaisur, and this is the more probable in the former river, 

 because rises, formed of the rock, approach to within no great distance of 

 the stream every here and there on the south. There is rock near Bho- 

 sawul, at the spot where the railway bridge crosses the Taptee, although 

 alluvium extends for some 15 miles to the north. 



Very little needs description in this section : for the few remarks re- 

 quired, it will be most convenient, as in other sections, to commence to 

 the east at Boorhanpoor'^ and proceed westward. 



Below Boorhanpoor very little rock is seen in the Taptee. North 



of the town there is thick alluvium, but a little 

 Country near Boor- 

 hanpoor. to the west trap comes in. On the north, on the 



road to Asseergurh, trap is met with. About 5 miles from Boorhanpoor, 



near to this spot, a little east of the road, and about a mile north-east of 



the village of Choolkhan, there is a singular patch 

 stonrnear ChooSfha?.''*^" of limestone.f It is compact, but shows no signs 



of crystallization, and it appears to contain no 

 fossils. It is quite isolated, all around being trap, and about 50ft. in 

 length. At one end of it, there is a white sandy rock, resembhng 

 decomposed gneiss in appearance, and standing on end, as if it were part 

 of a vertical bed ; it however contains rounded grains and is probably 

 sandstone. Some red clay is associated with it. 



This mass of sedimentary rocks is evidently a portion of some infra- 

 trappean formation, very probably Lameta or Bagh, either brought up 



* The authorities of the Great Indian Peninsula Kailway miscall this place Boranpur. 

 t This was pointed out to me by Mr. Naher, Assistant Commissioner of Boorhanpoor.
