THE BLAST FURNACE BUILDING.
a Structure 1OOx165 Feet of Corrugated
Iron.
This building contains four blast fur
naces completed and a fifth one COM
uenced. The ores, ~tiuxes, and fuel are
wheeled from the bins to the upper or
feed floor, the ores and huxes being
weighed before being placed in the fur
mace. The furnaces are about l6 feet
high and in the crucible measure 42x92
inches. These furnaces are built close
to and facing the river, where TIE banks
are high and afford ample room for the
elag dump. They are provided with
steel water jackets made Of five.slxteenths

Ventilation of the Furnaces
This has in the past been one Of the
serious drawbacks to the health Of the
workmen attending furnaces, cases
of lead poisoning being extremely fire.
quent and the work extremely deleteri-
GUS to the health. This has been duly
provided for and due provision made for
the escape of the poisonous gases. The
furnaces are of Mr.. Eiler's patent, with
closed tops, being fred from the side.
The feed floor extends only to the front
of the furnaces and is shut off from the
entire front of the building by a wooden
partition slanting backward to the ridge
pole Of the roof. Thus a hood as long as
the furnace building and twelve feet
wide reaches from the level of the feed
floor to the v~entilator and draws off all
fumes and smoke from the tap hole,
Stag pot, and lead we'll.
A down pipe four feet in diameter
takes the gases and 1ue dust into a large
flue which is of section sufficient
for ten furnaces, and the fiue dust cham
Der is 500 feet long. This connects with
a huge smoke stack twelve feet in diam
eter and $50 feet high.

of accident.
This power drives three blowers
Baker rotary No. TX, the largest size
made, forcing the compressed air into
the large blast pipes, which extends from
this engine room to the back Of the fur
naces, each furnace being provided with
connections with this pipe.
A so horsepower engine run a large
Thomson Houston dynamo, which sup
plies the electricity required by the arc
and ~incandescent lamps around the
works.
A neat machine shop connected with
the engine room has a 10 horsepower
engine, with bolt cutter, drill and lathe.

The steam in the sampling works ia also
taken from these boilers, being led a

Provision has been made in the DISPOSE
