MALLET, VINDHYAN SERIES. 67 



At their eastern end the lower Rewahs have a thickness of about 

 500 feet, but if we follow them along the Kymore hills, they are 

 found gradually to decrease, and finally to die out altogether. 

 Thus, south-west of Rewah they are reduced to 400, at Badanpur 

 to probably not more than 100, and not a trace of them remains 

 north-west of Kuttungee, where lower Vindhyans and upper Rewahs 

 are in contact. The possibility of this not being a final overlap and 

 the shales of Jamghur and Mehalpur representing the lower Rewahs 

 has already been discussed. To the north we find —

sub-group, except perhaps the sandstone, gra- 

 dually diminishes in thickness, until near Buxwaho the last traces of shale 

 disappear, and the great Kymore and Rewah sandstones are in contact. 

 This overlap is, however, not final, for as we shaU presently see, they re- 

 appear in the Gwalior country. A very clear case of overlap of the Pun- 

 na shales to the north is observable at Kissengurh. The town is built 

 on the lower sandstone which terraces out about a quarter of a mile from 

 the scarp. At Kissengurh there is about 20 feet of shale beneath, but to 

 the east of the town, on account of less denudation, the sandstone stretches 

 stiU further north, and is then found to rest directly on the Kymores. 

 Further east at Babupur, near Adjigurh Fort, another case occurs, where, 

 in the main scarp, the lower Rewah sandstone is underlaid by the Punna 

 shales, while to the north it reposes directly on the Kymore group. It 

 is clear that the overlap is due to the Rewahs having been deposited on 

 I ( G7 ) .
