sandstone, resting at what may be an original inclination of deposi- 

 tion. From Nagode or any central position in the great flat valley, 

 the Rewah ridge seems as high as the scarp of the Bundairs, and I do 

 not think it can be much less. At whatever point one crosses this 

 ridge, the section of the scarp to the north is nearly the same; on 

 the road just noticed for instance — " the lower half is composed of light 

 green and red crumbling slaty shales with some flaggy sandstones ; the 

 overlying sandstone is principally white, fine, thick and thin, iron stained 

 and with very marked oblique lamination," — these shales, as those 

 of the Bundair scarp, leave prolongations, and remnants on the low 

 ground to north, and these are cut off as was described for the Bundair 

 shales, by a rising ridge of sandstone. Wherever one may cross this outer- 

 most ridge of the Kymore sandstone, the same feature strikes one as on 

 the Rewah ridge, the surface seems to rise along the natural slope of rough 

 strata, ending to the north in a vertical scarp : this cliff rests, as I have 

 shown, on very different rocks according to the point at which it 

 may be examined. Since the change of direction in the scarp, the 

 plateau of the Kymore rocks has become much contracted, the cliff of 

 the second table land rises very soon after the slope of the Kymore 

 sandstone has disappeared under the level. 



Having thus sketched the entire section of 

 the Vindhyans, before proceeding I would make 

 a few remarks about names as there are here evident facilities for 

 grouping.

1. — Bundair— sandstones, shales. 



2. — Rewah — limestones, shales and sandstones. 



3. — Kymore — sandstones, limestones and shales.
