Early ia 1890 Ia,Oi Kelley, John Christie,

other Escanaba gentlemen purchased an

still remained ia charge. A shaft was

iect Mr.. Sheridnn's management not
lring satisfactory 90 his Escannba sissu-
ciates, they purchased what remaining
interest he had and employed Captain
A. Giilgren, then uf the Gogcbie range, as
superintendent. Upon taking charge
Capt. Gulgicn made a careful exntnina-
ton 81 the premises and decided from
the nature al the formation, that the
ore must lay TO the north Of the shalt
and commenced To drift in that direction.
4 hey drifted through about twenty-five
feet Of mixed ore and there encountered
about fifty feet oI rock after which they
struck good, clean ore, into which they
dIifted about forty ieet and cross-cut
about twenty-five feet without eucount-
ering the rock walls. Alter thus proving
the existence ~ a considerable body 81
ore, they sunk the shalt down about
ninety feet deeper and again driied to-
ward the ore, running about 100 beet
btfurc clean ore. They then
passed through ten feet ~ u fine qumliiy
III clean ore, passing through this They
continued ON through al,niit fifteen fes't
OF rock aud mixed ore when they again
encountered the ore but havenot driftcd
into IT, They then went hack Ia within
nbnnt forty feet 81 the shaft and started
n drift to the west. going about Thirty
feet through rack when they encountered
thirteen foot vein ~ good clean ore.
They then started n diift 10 the north
west about eighty feet from the shnft
and ut distance 81 about twenty feci
encountered clean ore into which They
diiftcd ten i,rt and stopncd. Having
thus tested and fully established the fact
that they had Lirge quantity of ore
they took n lense al the property and
ceased further exploratory work until
they could make n sale oi some ore
The owners who had hitherto been only
u copnrtnerShip then incorporated
under the name 81 the Sheridan Mining
Company. They recently made u sale .uf
all the ore they could mime and ship this
season, and commenced mining oper-
niiuns. Tiny commenced 10 work in
