The rocks exposed on the banks of the Sher Nuddi between the 



villages of Berkera and Sehora furnish an exam-

pie of such a section. It is difficult to escape the 



conviction that here the upper portion of a great anticlinal bend has 



been removed by denudation. Ascending the stream from Loreta 



village we find the schist-limestone succeeded by hornblendic and other 



gneissose rocks, above which again the limestone re-appears and is seen 



faulted against the upper Damuda beds at Sehora: little can fairly be 



argued from the dip of the rocks in this section, the beds are nearly 



vertical all along, and when perceptibly inclined, do not long continue 



constant to any one direction, still no one could walk over the rocks 



exposed without being impressed with the conviction that the crystalline 



limestone seen faulted against the conglomerate under Sehora Village 



must be a continuation of the lithologically similar limestone bed seen 



lower down the stream— See section No. IV, pi. II. 



Another pretty clear instance of the probable repetition of a long 



series of recognizable beds occurs in the north

east portion of our map. 



In passing from Bursa village in the Mahanuddi valley, to Piprod on 

 the great Deccan road (see map) the strike of the metamorphic rocks 

 is crossed nearly at right angles. 



The low hills among which the road lies, expose the rocks almost con- 

 tinuously, crystalline limestone is frequently seen at the surface, and the 

 observer cannot fail to be struck by the regularity of the intervals at 

 which its outcrops recur ; near the villages of Magaruth and Dongurgaon 

 a long series of beds of the schists, besides these remarkable limestones, 

 may be very clearly traced, and are seen to be very exactly repeated, 

 some of the best marked beds of the set following each other in regular 

 order, and recurring in the same order very exactly. 



The evidence furnished by such cases as these does not, as above 

 stated, amount to proof, though it may be accepted as a sufficiently near
