BUNDELCUND. O 



Sone, the rocks on the south of the Vindhyan table land. The 

 coal-bearing series was then the special object of examination, so 



that remarks on the totally distinct beds to the

North or it were only very cursory; how- 

 ever in the many sections I then saw there was nothing to con- 

 tradict the possibility of all these beds belonging to one formation, 

 under different states of modification. The Vindhyans proper, which 

 to the N. W. of this line are so markedly undisturbed, here show 

 signs of having partaken in some great phenomenon of upheaval, — there 

 is the wonderfully continuous direction of the scarp, such as no denuda- 

 tion could work out unguided, the Section too is not the same as on the 

 North edge, its type may be taken from the Kymores (see Fig. I.)

On approaching across the Table Land, the beds themselves are seen 

 to partake in the rise of the ridge. This is most evident in the sections of 

 the South face : the undercliff is always very much covered and cases 

 of actual superposition are very difficult to be found. The next rocks 

 seen, about the river, show what might be an intermediate condition of 

 disturbance, while the rocks in the hills to the South are vertical and 

 contorted in the highest degree, being also abundantly associated with 

 igneous ( trap) rocks. Until then some fact should deny it, it seemed 

 safest to adopt the simplest case and to suppose the series one, and in 

 my notice of the season's work, I gave them the vague designation of 

 Sub-Kymore, under which name Mr. Oldham still left them in his 

 sketch of progress, read to the Asiatic Society of Bengal, in May 1856, 

 describing them however all as crystalline schists, &c., as the lower rocks 

 are in the Nerbudda valley, whereas in the Sone vallev, the strata
