Judging from the section (tig. 45), most of the faults are apparently reversed

as to the identity of the fragments of vein in the east drift and those in the northern 



half of the south drift, for the connection is nearly continuous. 



The fragment shown in the south end of the south drift is 30 or 40 



feet distant from the fragments farther north, and may represent a || 



closely parallel vein; on the other hand, it is identical with the

other vein blocks in size, strike, dip, and appearance, and there is no necessary 

 reason for separating it from them. The short drift running east on this southern- 

 most vein fragment shows conditions identical with those in the main east drift 

 (fig. 47), the vein being upfaulted to the east by close-set, apparentlv reversed 

 faults.
