case Of any failure of gas from the fur
naces, the steam conld be kept up without
it. The argand burner is used in connec-
ton with the boiler, thus giving the engin-
Ger full control over the gases, as they are
used to fire the boilers. Every boiler has
cast iron fronts and are made to present a
solid, and to the sight a pleasing appear
ance.
These boilers also supply the steam hoist,
and the steam pumps. For the purpose of
draft, the boilers are provided with two
large chimneys of brick. each one being
the shape of Il star, 80 feet high, and COW
cred with heavy cast iron cap.
The engine house is a building 74x4S feet
and central to the boiler houses. 1t CON
tains two large lever beam engines of an
entirely new construction and arrangement,
each engine being of 400 horse power.
The main features of them being the diff
ference in the length of the steam cylinder
and the blast cylinders. The connecting
rod attached to the crank shaft, being equi
distant from the centre with the blowing
cylinder attachment. The steam cylin-
tier attachment being placed at the
extremity of the beam, beyond the crank,
connection, traverse through an area of
greater length, giving the steam piston more
travel, thus allowing the large fly wheel,
which is of32 tons weight, the possibility of
extending the force of its momentum, to
greater advantage than in other engines.
These engines are placed on massive
foundations of cut stone, under which anoth-
or forest of piles were driven ever which
are placed bed plates of enormous weight
-Four massive iron columns support the
superstructurc, the heavy beam of east iron
and all its attachments. These engines
have been designed with the intention of
making them the engine, spar excellence"
economical, simple ard accessible in all
parts and durable.
Great economy is expected from expan-
sion of steam. They are also arranged so
rs to work as condcnsing ard high pressure
engines. such one beng provided with
valves, to effect the change from one to the
other in Il moment. As condcnsing engines
they are not intended to carry over 20" to
the square inch.
When working high pressure about 80
twill be required. The boilers being tested
at So are of ample strength and capacity to
provide all the steam required. The dmen-
sions of the engines are as follows: steam
cylinder 80 in diameter by Is - feet stroke.
Blowing cylinder 81 in diameter by 10 feet
stroke. The speed of the engine will depend
on the requirements of the furnace but will
probably average ~ revolutions per minute.
In tine engine room are located the steam
pumps in number. They are of the Blake
type, especially made to work with low
pressure steam, and will supply all the wa
ter wau;cd around the furnaces for the
twyrc or other purposes. These pumps re.
cicyc their supply of water through two 10
ineh cast iron mains, placed in tunnel built
out into the lake, a distance of30O feet from
the pumps, either of these mains being sut-
iicirnt to supply the pumps In case the ether
one should fail from any cause.
\ complete system of fire apparatus is
connected with the pumps. for the purpose
of cXtinguisling any fires of ilcgtimatc
character around the premises
One feature of these furnaces will cspc-
cially strike the practical man, VIZ, its nc-
feasibility. carriage can be driven around
every building forming the plant, thus af-
fording facilities for operating not found
everywhere.
The day has gone by when furnaces. it
was thought. could not be built except
against side hill. Railroad and water
transportation has allowed furnaces to come
down from the hills and locate upon the
plains, where ample room. ventilation and
light take the place of darkness and
mysterious passages. where none but men

nancCs were built under the personal super-
vision Of General John Hammond, president
of the company, from plans furnished ~

The amount of iron daily produced will |

used, and $4,000 tons of anthracite coal |
will be yearly consumed in the furnaces.
One year from the day that ground was
first broken the furnaces were ready to go |
in blast, nothing preventing but some
finishing touches that had been delayed last |
fall at the time of the panic. il being
thought then that there was no hurry to
begin making iron. This instance of
building two furnaces in the space of one
year is unprecedented in this country. and
the fact tina, Crown Point is in
n measure isolated from the centres of sup
ply. is rare instance of rapid building in
fact experienced iron masters of Pcnnsyl-
Yania pronounce il an impossibiity and
ridcule the attempt However the Crown
Point furnaces would he in blast this day
had it not been that the building operations
were in part suspended during the darkest
lays of the panic
1t is intended to manufacture Bcsscmcr
pig iron at these furnaces from the ores
taken from the company's mines, their
purity beng such as to permit this. lIcs-
5cmcr pig iron manufactured in the United
States is Il necessity of the day. Our steel
works have been tributary to England
almost exclusively for that article, its price
having more than doubled in the English
market within five years, and in consequence
Dt the limited supply of suitable ores to
make sufficiently pure pig metal becoming
'mallerevery year, it is absolutely necessary,
IN order to supply the growing demand for
steel rails, that metal of n good quality and
n lair prices should be manufactured here
This. 1t is confidently expected. these
furnaces will he able to do with the Crown
Point ores, in fact, il has already been ac-
Il, the old charcoal furnaces of
Ncssrs. Hammond, where iron was made
hat largely entered into use in the BESSIE
ner steel works At Troy and elsewhere.
To give an idea of the purity required in
ne bcsselncr metal, the simple element of
that great enemy to steel
makers, must not enter into the chemical
of pig iron to the extent of
more than eight or nine one hundrelhs of
)nc per cent, and as much less than that as
possible. Ores of sufficient purity have
leen rarely found in the eastern states, to
Enable makers to obtain these results. A

Iron Mountain ores of Missouri

character alone.
The means Of transportation of the iron
Produced at the furnaces is sufficient to
transport away daily their entire products.
