BUNDELCUND, 87 



Leaving out of sight these tvvo cases, of which more certain knowledge 



is required, we get from the remaining hills of 

 Denudation. t „ 



the laterite group some very plain facts. From 



the manner in which the lower trap fills in existing valleys in the sand- 

 stone ridges, as on the south of Buxwaho, we see how approximately the 

 denudation of the Vindhyans had assumed its present shape and dimen- 

 sions, before this outpouring ; this remark of course extends itself by pro- 

 bability to the area of lower Bundelkhund and thereby smooths down 

 the objections to considering the Tingunnah trap as belonging to the 

 older series, it bearing the same relation to the rock on the plateau 

 over it, as that at Saleia does to the basalt on the Rewah ridge 

 at Sasa. 



The laterite outliers give a different account of the east end of the dis- 

 rict. Previous to its deposition denudation had made some progress, as 

 is attested by the hill at Simereah where the group rests on the Bundair 

 shales, but it is only at their outer limit, not as at Puturia where the 

 basalt stands well out in the valley. This is however of the nature of 

 negative evidence, we have the fact direct in the lofty outlier near 

 Manikpore, how extensive denudation must have been here in late times. 

 This hill with its lateritic peak stands several miles out from the plateau to 

 which it belongs : the distant outliers of the Bundairs show the same, 

 the blocks of rock laterite on them could only have got there before 

 their isolation from their plateau.

the extinction theory. which they are most commonly seen, is in favor 

 of the notion I started regarding the original partial extinction of the 

 Vindhyan series : if these rocks had ever risen, even at a much reduced 

 thickness over their present north-west limit, it is almost within cer- 

 tainty that along so extended an area some more prominent vestige of 

 them would have remained, but there is none, and these laterite masses
