VINDHYAN FORMATION. 



I now return to the Vindhyan rocks : — " at Dooreha, south-west of 

 Nagode, the scarp of the Bundairs is formed at top 

 by about 100 feet of fine red sandstone ; the change 

 is rather abrupt from massive beds of this to thin red shales and grits ; 

 in both, ripple-mark and a pitted surface, as if formed by clay galls, are 

 common; these red rocks are underlaid by yellowish gray, concretionary, 

 micaceous shales — in the sandy layers are some markings which might 

 be mistaken for crushed stems." 



From this point to Punnah is directly across the ledge of the Rewah 

 table-land. On this plain one can always get sections after a little 

 search: — for some way from the base of the Bundairs any rock one 

 meets with is of the same type as those forming the lower two thirds of 

 that range, thin variegated shales, both pure and sandy; at a greater or 

 less distance out according to the slope of the ground, these are found 

 to be interstratified by some 20 or 30 feet of limestone, and are generally 

 impregnated with calcareous matter. These strong beds determine a de- 

 cided rise about half way between the scarps, this being the average 

 position of their outcrop; as at Nagode, Lohargaon, Nursingurh, Puthuria. 

 The constancy of the aspect of these beds is as remarkable as that of the 

 rocks of the scarp ; from Rewah, to Nagode and Puthuria, where they 

 become covered by the superficial traps, their lithological and stratigra- 

 phical characters are the same. 



" The rocks in the river above Nagode are very thinly but regularly 



bedded flagstones and shales, the former yellowish

gray, the latter greenish yellow and purple, the 



ingredients mix variously, some shales being gritty, and some sandy 



layers earthy ; the calcareous element shows, by its presence in thin 



irregular sparry strings, or by its removal leaving crumbling ochreous 



bands. All these have so gentle an inclination to the south that it could
