down from the Slopes is thrown from
platforms down into the mine cars
which are drawn into the mines by
horses, When car is filled two
trammers step upon a step at the rear
of the car which is then started for
the breaker house. At the right of the
car is brake controlled by the foot
of the trammer upon the side, but
this is rarely used and the cars go
or a fast express train. Near the en-
trance to the tunnel an up grade is
struck and by the time the car reach
es the breaker house, a few rods be-
You'd, it is under control and is made
to stop at the emptying point where
the ore is shot down over big screens
to the floor below where the large
pieces are pushed into the breaker, is
broken into fine pieces and descends
on an endless belt beside which sit
boys who pick out the waste. The
ore, carried upon the belt, goes down
into cars upon a track running above
the roast beds and from the cars is
emptied upon the bed upon which it
is roasted until large part of the
sulphur it contains is roasted from it,
breaker house is run upon a side track
near the entrance to the mine and
as soon as the next ore-laden car pas
ses it a horse is attached and a lively
boy, who is the driver, trots the horse
up into the mine at lively gait.
Halfway in, he meets the horse and
driver which took in the car that has
just gone to the breaker house with
a load. There is plenty Of room in
the tunnel and he is soon past horse
and driver and has his car set upon a
track at one end or the other of the
drift, ready for it's load. A loaded
car is sent out and the driver, who
has just come in with the empty car,
starts back and loses no time in get
ting out of the tunnel and out of the
way of the car he took in, which will
soon be rushing past him.
Immense Stock on Hand.
On the roast beds q few days ago
there were $4,000 tons of ore roasted
and ready for the smelter. A strong
man might be able to lift and carry
to the smelter 100 pounds of ore. If
able to do this he would have to make
100000 trips before he could complete
the carrying of the ore upon the beds
to the smelter. A small railway
runs close beside the roast beds and
in getting the roasted ore from the
veyed to the smelter chutes the work
men have to do more lifting than in
any other part of the work. The cars
run into the upper part of the smell
ter where a side of each car is dropped |
and the ore slides down into great
chutes at the lower part of which are

steam power, keeps the fire very hot.
so hot in fact that were it not for the
water jacket surrounding the furnace
and through which cold water is
under heavy pressure the fur
mace itself would burn ont From the
furnace the copper runs into a large
'eservoir of brick in which the heavier
copper sinks to the bottom, leaving
the Stag at the top. Until recently
the removal of the Stag was one OF

ITO egg-shaped vessels and after cool

ntO a stream. Very often there would

he water and the metal would fly

lag runs into a large iron trough and,
is it falls into this it is struck by
wo-inch stream of water running
lnder heavy pressure and is immedi-
ltely converted into shot, which run
lown the trough to the stream, which
quickly carries the shot away. The

eservoir, or steep, into a series OF :
