hundrod-ioot Icvel--the thi,sl--a drift IL
driving south and will be caused to con-
meet with n lenze Of ore lying south ofth
shalt. In a few days a eross-cut u also
TO he commenced, which will cut the ore
on the east. the distance il estimated AT
about twenty feet. This lenzc OF ore also
exists in the second level.
Shaft No. 3.-This shaft at present Inns
a depth Of two hundred feet ana is being
lowered to the third level, fifty feet Of
which yet remains before the shaft rests
in the 800 footlevel The shaft is located
in rock, which in the first level was
crossed 40 feet, where a lenze Of ore 45O
long 10y forty Teet wide was penetrated.
In prosecuting To the vein in the second
level arich discovery was made and devel-
oped nothing less than an entirely new
leDze Of ore showing width Of ninety
feet, lying parallel and west Of what, by
way Of distinction, will be called the
old vein the top Of the ninety foot lcnze
did not extend into the first level, but
developedin length 60Oieet IN the second
level The old vein has in the second APP
proximately the same length and breadth
AZ in the first level. From the second a
Wine is being put down TO the third
where y connection for vintilating pur-
poses, will bc made with the shaft, which
is to be bottomed at about the same
time. What remains Of the first level OF
the old vein Is TO he stopped 20 the surface
and the ore milled to the bottom Of the
mine from whence it will be hoisted. The
north end Of the new vein extends up to
and under No. shaft
Shaft No. 5.--This shaft * in. the foot
wall, which occupies the east side Of the
mine; the shaft is in course of sinking, the
depth now being ninety-iiye feet. When
200 feet deep stopping will be commenced
in the second level while the shaft will con-
tinue con- down 60 300 feet. All possible
speed is being employed in the sinking
In the second level the vein will be cross
cut east and raise made under the shaft
The shaft is 6xl6 feet, three compart-
ments, which admits Of double skip
road. No. > shaft is located $50 feet
south Of the north line OF the property
but beyond the shaft nothing is known
OF che ground further than what can be
seen ON the surface.
Shaft No. 4.-Thc shaft SO designated
is located 500 feet south OF No. /, and
has just reached a depth OF 40 feet where
il will rest for time The shaft is re-
moved 500 feet from any Of the other
workings, the nearest approach being the
south extension from No. L. The shaft
is in rock and on all sides is virgin
ground, which il IN the duty Of this shaft
TO assist in exploring. Near the bot
tom n cross-cut il soon 90 he started
wost, in the direction Of the river
in hopes OF cutting lenze OF ore
supposed TO be located in that locality
and from indications presented at other
parts Of the property, there is no reason
why the calculation should miss fire, the
formation is identical. Owing to the ma
ture of the ground il was necessary TO
put the shaft down TO SO great a depth
before exploratory operations could Toe
out. IL will undoubtedly be-
come necessary 60 work up 20 or even
under the river and that could not be
successfully accomplished without first
lcavinga heavy back. Considera bile water
makes in but the machinery in use takes
care Of il so fast as il comes in and no
time is lost from that source.
Isabella Pit.-From the name the read-
or may be led 60 believe that tins part 81
the mine is 81 little consequences, but
il the Iron Rivers output would
be decreased at least one-third. Whileit
IL not the largest il Is certainly the most
part Of the mine. Previous
60 last year the Isabella mine was worked
open cut, produced large output and
a large cash in the earth left opcn There
il one shaft located in the west, having
n depth OF 225 feet and the work DIGGING
down an additional fifty feet Co the
fourth level is now in progress, thirty feet
Of which yet remains Co belowercd before
the work will be completed. In the first
level which includes the open pit, the
pillars OF ore left for support during min
ing, are now being taken out, and all OF
the ore on the sides il being removed
this work done away with the pit win be
filed with rock. In the second level a
Stope thirty feet wide is being cut out at
the south. Not long since IL was thought
the ore had played out, but in sinking
