parts at least_, be intertrappean^ more especially as blocks of typical 

 intertrappean beds with tlie usual fossils {Cy prides and plant remains) 

 occur near Taklee. The Bhorla limestone contains irregular cherty lumps 

 and fragments of fossil shells in abundance, (a) 



To the north of the tank^ the ground is covered by black soil. 

 About i or f mile north of Bhorla the Vindhyans crop out. Just 

 south of them, and resting upon them, are sandstones and conglomerates 

 precisely similar to those imderlying the traps in Dhar forest, and to 

 the beds of Alumpoor, north-west of Baitool. There can therefore be 

 little question about the occurrence in this spot of beds of cretaceous 

 age. 



Some of the conglomeritic sandstones north of Bhorla have very 



much the appearance of the Vindhyans, an 

 Cretaceous beds formed 

 from detritus of Vindhy- appearance due to their being composed principally, 

 ans. 



if not entirely, of detritus derived from those beds. 



On closer examination the difference is easily seen, the Vindhyans are 



dense, homogeneous and compact, scarcely a trace of structure being 



discoverable, while the separate grains of which the cretaceous beds are 



formed may be distinguished in general with the naked eye. The jungle 



covering the two rocks also is very distinct. Here, as elsewhere, that on 



the Vindhyans, is characterized by the absence of underwood, the thinness 



of the grass, and the prevalence of the Salee (Boswellia thuriferaj, which 



in places is almost the only tree, while the jungle on the cretaceous beds 



is varied in kind, and both grass and underwood are thick and luxuriant. 



Vindhyans continue nearly as far west as to opposite Burwai and end 



Vindhyans north-west ^lose to the spot where they cease on the north 



bank of the river. A few patches of overlying 



trap occur upon them. They present no features of interest. 



(a). Mr. Wynne obtained marine fossils from Bhorla, but it is not quite certain fi-om what 

 portion of the limestone. It was before the beds of this part of the country were well known. 

 It is clear that both intertrappeans and cretaceous beds occur at this spot.
