New Plant Works Like a Charm
First Eoonomizer In These Parts.

Corrigan, Mckinney & Co have the
most complete and modern plant at
the Tobin mine that is 10 be found
anywhere in the peninsula outside Of
the copper country and there are but
few in that boasted locality that equal,
not to speak Of aurpassing. the Tobin
equipment in point Of effectiveness aud
modern ideas For nearly p
year program Of improve
ment in the machinery end Of this
property has been carried On and, In
conjunction with the surface improve
ments. the underground workings and
the shafts were being put IN shape
commensurate with what was 20 be-
on top The WORK is completed, botn
underground and on surface.
Beginning at the power end Of the
new engine house the visitor meets
with four i25 h. p. boilers Of high
pressure type carrying as high as $50
lbs pressure These boilers are
horizontal type and every improve
ment known has been taken advantage
Of in the setting.
An interesting part Of the equipment
is the economizer connecting the boil
ers with .he big stack In this econ
omizer all OF the gases and combustable
material in the smoke are gathered
and turned TO the heating Of the feed
water. IL il the first OF its kind in use
in these parts and is proving wonder
fully saving upon fuel. Under the old
sytsem Of using exhaut steam etc, the
feed water was heat 10 temperature
of POO degrees but with the new device
il il heated TO 300 degrees.
! The engine is OF the Nordberg manu-
fracture. is first motion with drums ten
feet In diameter The installment Of
this hoisting plant followed 80 shortly
after that at the Great Western that
the operators were able 10 avoid any
short comming found in the Western
plant and thus the Tobm plant is as
prefect as 10 could possibly be got.
Standing beside this mammoth hoist
is the big Imperial Type Rand com
pressor. capable of handling thirty
drills, II is the very latest machi ne
put ont by the Rand people and con
tains all OF the latest improvements
The shafts, which We're des-
cribes at length short time ago are
equipped with double decked cage
fitted with saftey appliances for the
handling of men. timber etc This
cage is pulled by separate engine
and hoist used only for that purpose.
The new electric haulage has been
ordered and Is expected at the mine
shortly. 1t il manufactured 10y the
Jeffry Manufacturing company. The
motor Is Of five ton capacity ana IL the
very latest that can be mad. The work
81 installing this haulage will com.
mence as soon as the machinery ar
rives and when IL IL in the Tobin will
begin TO put out ore at rate never
dreamed OF before for q Crystal Falls
property. II Is expected that at least
20OO tons per day will be put out from
the property.
The Tobin sets at rest, once for all.
the theory that has been held 70 In the
past, namely that there are no large
ore bodies in the Crystal Falls district
The Tobin is entitled 10 take its place
With the very large mines Of the
Michigan ranges, for its size and the
continuance Of the ore body 10 very
great depth has neen amply proven
