the Semri, its present stream flowing in the opposite direction to that of 

 the river by which it was formed. 



For the Kane too, we may ask, how does it come to cut a precipitous 



gorge some 15 miles long through two hi^h ridges

of massive sandstone, if the present open valley 



existed to the east ? It must have been done before this valley was there 

 when the Bundair plateau ran up level to the Rewah sandstone and its 

 drainage falling over the scarp produced this gorge. Or perhaps it was 

 effected when the trap and laterite had reproduced a tolerably even 

 surface over the incipient Vindhyan ledges : the other supposition would 

 involve the seniority of the present gorge of the Kane to the oldest trap 

 at Puturia, thus affording a certain outlet to the waters of the supposed 

 lake. In either case, we have in these gorges the evidence of a period when 

 the aspect of the country was different from what we now see, a period of 

 river action prior to the more recent submergence by which so great a 

 mass of matter had to be removed. 



A more minute survey with some accurately levelled sections would 

 enable one to carry these inferences and conjectures much farther — I 

 have only shown that the facts are favorable for such treatment. 



Note on the Iron deposits. 

 I have given in their respective places notices of the geological condi- 

 tions of the several worked iron deposits. I will here only add a few 

 general remarks. Until the question be settled as to the production of 

 iron on a large scale and without coal, it would be waste of time to collect 

 and work up the statistics of these iron districts, as they come under this 

 condition ; it would only be diverting attention from localities that have 

 been already prominently brought forward and to which these do 

 not offer any manifest superiority ; if the experiment does not succeed
