NERBUDBA DISTRICT. 133 



approach to demonstration ; as far at least as the fact that beds are 

 repeated again and again at the surface, and thus exposed by the re- 

 moval of the upper portion of anticlinal bends, by denudation. In order, 

 however, that such evidence should be used to furnish measurements of 

 thickness, or even materials for a fair estimate of thickness, it would be 

 necessary carefully to record on an accurate map very carefully measured 

 sections, especially where the dip is so high that its deviation from the 

 vertical is often very difficult to observe, and thus little more can now 

 be stated than that after we have made allowance for flexures, there is 

 still ample evidence of very great thickness left. And this must have 

 amounted to many thousand feet: taking only the typical schists of 

 the Nerbudda valley itself, and excluding the sub-Kymores above and 

 all the more gneissose schists of the Betul and Chindwarra country : 

 rocks which belong to the same series and which may be themselves of 

 enormous thickness. 



Again, we find in these recurring beds evidence of the action of those

and disturbed the schists. The kind of evidence 



on this subject which is afforded by a flat country is never so striking, 

 as when the contorted beds can be seen on the face of escarpments, or 

 the steep sides of high hills, and the lines of flexure traced by the eye, 

 but it is not the less reliable on this account — indeed if the recurring 

 beds be complete and satisfactorily identified, then the flat ground not 

 only proves the existence of flexures on a great scale, but also the re- 

 moval by denudation of vast masses of rock. 



It was stated, when describing the granite that no direct connection 



could be traced between the presence of that rock

and the disturbances of the schists ; a case illus- 

 trating this occurs near Hinhotia hill (see map.) A considerable patch 

 of granite is here found, all round it the schists seem nearly vertical ; 

 on the north side of the hill however a constant though slight deviation
