the period of the rock-laterite because that rock is now found capping' 

 outliers separated many miles from the escarpment, but such submer- 

 gence, if it ever occurred, has left no collateral evidences of its existence. 

 The escarpments exhibit the usual tendency to conform in direction 

 with the strike of the strata, when the latter are not strictly horizontal. 

 Amongst many fine examples of this, a good one occurs at Hoshungabad, 

 where the strike of the Rewah sandstone, after observing a steady east to 

 west direction for twenty miles, suddenly turns round to north-west — 

 south-east, and the same alteration immediately takes place in the direction 

 of the scarp. The form of the escarpments also depends much on the 

 bedding. When the latter is horizontal, and still more when it dips frona 

 the former, the escarpment is nearly always precipitous above, with a 

 steep talus-covered underslope ; but when, as rarely happens, the beds 

 dip towards it, it degenerates into an easy slope from top to bottom. 

 The form is also influenced by the relative proportion of shale and sand- 

 stone, of hard and soft beds. The Kymore and Rewah escarpments. are 

 bolder than the Bundair on account of the greater hardness and massivie- 

 ness of the strata.^
