BUNDELCUND. 51 



20° and 70° east of north but I noted some going east-west and also some 

 west of north — the east-west tendency prevails in the north of the 

 district. The ridges themselves do not appear every where; there is a 

 large area in the south-west of the region quite free from them. I re- 

 marked of a ridge south of Shergurh near Nurwar, that it seemed made 

 of several ribs of quartz which cut each other both in dip and strike. 



In the bed of the Betwa at Bussour ghat, I crossed what appeared 

 to be a worn down quartz ridge, striking east-north-east, cutting through 

 red granite and trap ; intimately associated with the pure quartz mass, 

 was a quartziferous petrosilex : they appear to have had an influence 

 on the rock in contact, being rather an abstraction of silex than an 

 impregnation with that mineral. These quartz dykes and the several 

 varieties of trap which abound so throughout the crystallines, would 

 afford most interesting study to any one resident among them, and no 

 one else can take them up with the same advantage. 



While on the subject of quartz I would notice a remarkable accu- 

 mulation of this mineral that occurs in the granite, between two hills 

 above Kareia — there are two isolated oval masses of pure quartz of 

 about 20 yards by 10 in the midst of the granite ; with the quartz are 

 some nests of felspar in large rhomboidal crystals : the masses being 

 in fact, of very coarse pegmatite. 



The scarcity of accidental minerals among these 



Minerals rare. „ . , 



rocks is remarkable, even ol those that are so 

 common in the crystalline rocks throughout India, as magnetic iron^ 

 schorl, garnet.
