NERBUDDA DISTRICT. 263 



savant himself furnishes us with examples among those systems of pairs 

 of range lines, of different supposed age, which if produced into a juxta- 

 position such as we here have, would exhibit a parallelism perhaps 

 even more complete than that which we attribute to the Vindhyan and 

 the Mahadeva faults. Again, we may have neglected the modifying 

 action of a more recent and nearly parallel movement on the physical fea- 

 tures from which we have estimated the direction of the Vindhyan fault. 

 Aware of all these sources of error, and fully alive to the fact that 

 neither the closeness of our acquaintance with the structure of the 

 district, nor the exactness of our observations, even within that portion 

 of it which we have more carefully examined, will warrant us in believ- 

 ing that the application of this theory can here be satisfactorily made, 

 we still think that the objections we have felt justified in raising, and 

 our reasons for such, may prove useful to the geologist who may at some 

 future time more fully investigate this most important subject, as well 

 as of some interest to the general reader.
