The Isle Royale developments OF re-
cent period have awakened an inter-
est never heretofore exhibited IN the
AFFAIRS of this property, which may
wei 0e cited as an instance OF the
uncertainty of mining. considering the
fact that its initial operations date
back sixty years.
Interest al the moment centers
largely in the plans OF the manage
ment Co the end OF additional stamp
ing facilities. as al present this is the
barrier 10 greater production and
earnings The solving Of this prob
lem. however. Is believed 20 be a mat
ter of but a brief period. following
which for the drst time in its career
the isle Royale will De in position To-
90 itself justice.
There has recently been Witnessed a
broader scale OF activity, both under
ground and an surface New opening
work is being pushed and provision
made for the advantageous handling
of q iroatly Increased tonnage.

twenty feet OF the 80th level where
sinking was discontinued some time
since. The elst level has been ex-
tended under the Huron workings
Tho Huron openings are unwaterej
practically TO the 9th level. and viii
