Since orr last Publication NO have becntw zee
into the Minnesota Mine To lock Al his wonderful
piece Of copper \ few tons have Hrendy been
taken from II, aud there are some thirty men at
work cutting il up; more parties will be put on
soon. The lower end of the copper wa raised
by the powder from the rock IN which ii was in
closcd-thc upper end being very little d ,turbed.
This leaves il incinng but little from the hori

Large masses from this uue have generally

is no ground for such an apprehension. Ga the
contrary it. suli0ity is indicated not only hy its
external purity, but also by the manner in which
it resisted the action of the powder and rose from
