bars falls upon level screen made of
heavy iron bars, and here a man pounds
it until it all passes through. Then it
passes between or under great iron cylin-
ders driven by steam power, and is crush
ed until it will all pass through inch
screen. This crushed coal is elevated
precisely like -four in a Touring mill,
with small buckets or scoops on an end
less belt. AT the top, where the belt
passes over a roller the fine coal is pour
ed from the little buckets into great
boult, which revolves precisely like
boult in Touring mill Extending the
whole length of this boult, and directly
over it. is small water pipe, perforated
with numerous small holes, through
which streams of water fall upon the
boult. We cannot describe the compli-
Gated process in all its details. but the
crushed coal is sifted, and pounded, and
washed, and shaken, until it comes out
with all the slate, dirt, sand, and other
impurities taken out as completely as
modern separator will take the straw,
chaff, cheat, cookie, dirt, etc, from the
wheat. This purified coal is now lain in
heaps to drain, and we will leave it there
until we describe the great Belgian Coke
Oven.
At first sight, person would take this
coke oven for a huge hot blast at fur
mace 1t is made of brick and stone, is
% feet wide, and long enough to contain
"a ovens, 8 feet wide, with the interven-
ing walls The ovens run clear through,
and have heavy iron doors at each end.
Each oven is % feet long feet wide, 81
feet high, and $50 bushels of crushed
coal is a charge. This coal remains at
high red heat for As hours, when the
coke is ready to be showed out. Mr..
McLanahan handed US card with some
figures, among which it is stated that
each oven contains 10000 brick, and p
tons castings This establishment was
commenced in July, and cost $4,000.
The ovens are all lined with the cele-
brated Webster fire brick, and Mr.. Nc
Lanahan, who has been engaged in the
business, and examined various qualities
of fire brick, speaks very highly of their
quality. These bricks last for months,
some of them for years, as inwalls at fur
naces, where they are all the time sub
iected to intense white heat. Mr.. Miles
thinks there will be no wear out to them
in these ovens, where they are only sub
ljected to a red heat Mr.. Miles says
they are very complicated in their struc-
ture, fitting and growing into each 9th
er, and making perfectly solid walls. He
says that now, when their patterns are all
ready, and fully tested, the company can
manufacture them for other ovens much
more readily than they could for this
the first one.
The bottom and sides of each oven are
solidly lined with these celebrated fire
bricks. as we'll as the tops, which are only
arches made by continuation of the
sides. All along near the top Of each
oven are small apertures through which
the gas from the heated coal passes, and
is carried down one side, and under the
oven, and up the other side, and is burn
ed in its passage thus creating the heat
which keeps the fire bricks of the oven a
bright red in all its parts. This process
of making gas by heat produced by the
gas thus made, comes the nearest perpet-
ual motion of any thing we ever saw.
There are very small mica windows in
the doors of the ovens, through which
we could see the operation going on in
each oven, as the process of coking pro
ceeded, in its various stages. In the
ovens where the process was about com
pleted, the scene was grand and beauti-
full The wavy red heat reminded US oi
pictures of the corona surrounding the
sun at the time of total eclipse. The
wavy red heat was not fame, it was fer
vent heat
Mr.. RAIDER had notice that we were
coming, and he held back six ovens oil
coke to have taken out while we were
present. The doors on each side of the
oven were closed, and the interstices
closed with mortar On the east side OF
the oven, extending its whole length, is
a wide railway, with three rails. On this
railway is an odd looking engine, of 80
horse power. 1t can be thrown into gear
in one way so as to be moved along the
track, and thus brought opposite to the
door of any of the ovens. Then it can be
thrown into gear by lever so as to push
the coke from the oven There is a
square plate of iron, the width of the
oven, and some FIVE feet high. ION the end
of huge bar of iron. This bar is the
length of the oven, and passes under the
wheels of the engine, across the length OF
the platform of the engine. On the top
of this bar are notches. in which a small
wheel works. Now the doors on each
end of an oven are thrown open, the en-
CINE is moved until the plunger is exact
ly at the door. The lever is pulled, the
wheels begin to whirl, the little wheel
works in the notches on top of the bar to
the end of which the plunger is attached,
when it enters the door of the oven, goes
against the end of the mass of coke, and
the entire mass begins to move through
the oven Then we run around the end
of the oven to the other side On this
side, the entire length of the ovens, is a
brick pavement, gradually slanting from
the ovens. On this pavement gradually
comes the huge plug of coke. 1t had
about half filed the oven, and conse-
quently was some 81 feet high. and the
