66 BUNDELCUND. 



few remarks I have to make are more of the nature of additions than of 

 corrections to that memoir. Though supposed to be geological, it scarce- 

 ly hints at the most simple but necessary elements of a geological opinion: 

 the author says vaguely that the Vindhyan sandstone is " the depositary 

 of the diamond at Punna" — he speaks of the associated " slaty marls" as 

 " differing in no respect from those of Piperiya ghat," on the scarp of the 

 Bundairs ; but these remarks are more accidental than intentional ; for 

 he does not corroborate them by any direct evidence, or make a clear 

 statement of the case; so much so that Mr. Carter, in his summary of the 

 geology of India, published in the Journal of the Bombay branch of the 

 As. Soc. No. 19, 1854, deliberately superimposes the diamond deposit on 

 these Yindhyans and even derives the diamond conglomerate from their 

 debris, Franklin being his authority : but this license is excusable ; for, 

 from his written description alone and without visiting the locality, it is 

 evident that Franklin places together, without any comment, classes of 

 diggings that could not be in the same geological field ; he makes the 

 distinctions of "superficial deposits," "mines of transported diamonds" 

 and of " native beds," but with the latter he places the mines of Sakeriya 

 and Uclesna which the veriest tyro in geology could see to be diluvial. 



Franklin's description of the varieties of diamond and of the methods 

 of treating the ores seems very correct ; it is enough to say that the 

 work is carried on by natives, to make it probable that nothing has 

 been changed since the time of Chitrasal ; his lithological detail, of the. 

 matrix and of the associated rocks, are also accurate, so that I have not 

 much to add. 



It seemed to me an inevitable and most evident conclusion that the
