shales, and the second ridge of the Rewah sandstones : these sandstones 

 attain on their respective ridges a thickness that they never have when 

 away from them — over the gorges of the Boghin and the Runj, the 

 Kymore sandstone must have a thickness of 1,000 feet; whereas on the 

 ridge of the Kymores proper over the Sone river, at the point where I 

 crossed near Burdhee, there did not appear to be more than from 200 to 

 300 feet of coarse strong-bedded sandstone, the greater part of the scarp 

 facing the Sone being of thin-bedded, fine, yellowish grits, that may be 

 the equivalents of the fine shales noticed at Keriani ; on that Sone section 

 I saw no limestone referable to the Kymore group — the limestone at 

 Burdhee is distinctly infra-Kymore and much resembles the lower 

 Pulkoa limestone. 



As regards the extension of the Vindhyans to the north-west, it 

 N , . becomes a question whether the ridge of crys- 



of the Vindhyans. tallines which has hitherto presented such a steady 



face to the south-east, continues to do so beyond the bend in the scarp 

 of stratified rocks, and under the high ground to the S. W. I can 

 partly answer this in the negative — the junction surface of the granitic 

 rocks shows to some extent this deviation ; along the outer edge of the 

 scarp by Nurat, Palee, Jackloun, the granite rocks reach from \ to | up the 

 cliff, just as under the Semri sandstone at Shahgurh, or the Bijawur 

 breccia at Kutola, or again under the Kymores at Adjeygurh ; but, as 

 at these places, in the deep gorges the bedded rock soon reaches the 

 lower level; in the Betwah the granite junction cuts the river at the 

 village of Baranow, a very short way in from the general run of the 

 escarpment. However, this does not last ; at Sirsaut, a village at base 

 of one of the many table mountains which are here detached from the 

 plateau, the granite reaches nearly to the top of the hill, and looking 

 westward from the summit along the valleys towards Chandairee, I 

 judged that this was the case for a long way in — as the working season 

 was passed I had not time to follow up the junction. This scarp of
