flames. Outside the braces, thrust bars,
backstays and lie rods hold every part
firmly together, while the fire doors are
carried on heavy iron panels similar to
boiler fronts. Where natural gas is used
as fuel, or where there is but little wet
refuse to be treated, the construc-
ton of the furnace is changed somewhat,
although the principle of two fires is the
same. Experiments with such furnace
at Lowell, Mass, fitted with burners for
using crude petroleum, are now in pro-
gress, and it is believed that they will
prove very valuable, since liquid fuel has
many advantages over coal for the pur-
pose of garbage cremation, the chief ad-
vantage being the readiness with which
the fires can be started and stopped
PLACES THAT HAVE FURNACES.
In addition to the Engel furnace at Des
Moines, Ia, similar garbage cremators
are now in use at Butte City, Mont;
Findlay, o.; Birmingham, Ala; Jackson
vile, Tampa and st. Augustine, Fla;
Brunswick and Savannah, Ga; Rich
mond and Norfolk, Va; Lowell, Mass;
Salt Lake City and Ogden, Utah; Coney
Island, \. Y, and many other cities
where small furnaces are used. The per-
lormance of the two large cremators ut
Savannah shows what can be accom-
plished by a reliable manager with such
apparatus.
A JOLLY LOT BURNED.
From January to November so, 1882,
the list of articles destroyed is as follows:
LII cubic yards of garbage, GIL loads of
nightsOil, - barrels OF fish, II barrels of
onions. 80 barrels of apples, 49 COWS, 45
horses, 43 goats, 623 dogs, LOO cats,
snake, l monkey, l rabbit, sheep, 1867
pounds OF meat, 6,742 head of poultry, 8
loads OF oranges, Is loads of bananas, 13
loads of cocoanuts, loads of apples and
peaches, Is loads of peanuts, IS loads of
potatoes, l load of tongues, 1870 dozen
eggs and 305 pieces of infected goods.
The average amount burned daily was
l35 cubic yards of material at total cost
of Is cents per yard. The ashes are used
as fertilizer and for making roads about
the furnaces. The fuel employed at this
place is pine wood.
THE PLANT AT PANAMA.
Another interesting plant is at Panama,
in the United States of Colombia. Here
the garbage putrities so quickly that its
disposal is serious matter, which is en-
HANGED by the scarcity of fuel. Charcoal
is used for domestic purposes and coal is
imported for mechanical power. The
fuel used in the cremator is a peculiar
kind of wood cut on the coast, brought
by water to the city and split into
quarters before use. In order to keep
the quantity necessary for the fires to the
lowest possible amount, all the COM
bustible wastes in the city are collected
and used in the furnaces.
ANOTHER ODD LIST.
From January, 1891, to April, 1892, in
elusive, S,SS4 carloads of garbage and 769
dead animals were burned at a cost of
S2,264, or about 10 cents a yard. At
Coney Island, where anthracite coal is
used as fuel, it costs about IA cents a
pt1n nd tO rI,,o bo fr1rn
lay, Ohio, natural gas Is used very sue
cessfully. Reports for last year have not
yet been published, but during 1891 this
furnace consumed 3, 422 loads of garbage
3,7l9 barrels OF nightsoil, 100 horses, a
cows, 1l9 dogs and "A hogs, at a cost of
about IS cents a cubic yard. In places
where there is a large amount Of animal
matter burned. it has been found that the
ashes from such cremator have con-
siderable fertiliZing value.
STILL ANOTHER SUCCESSFUL STYLE.
Another successful type of garbage Gre
mator was erected by the Rider Garbage
Furnace Company in Pittsburg in 1887
and in Allegheny year later. The Pitts
burg furnace is rectangular mass of
brick masonry containing two chambers,
separated by a bridge wall of friedrich
three feet thick and having semi-circu-
lar opening in its upper part through
W
Der is about twelve feet long and six and
half feet wide, and the rear chamber
ten feet long and six and a half feet
wide. There are eight circular openings
in the top of the front, and six in the top
of the rear chamber, through which the
garbage is dumped. These openings are
Is inches in diameter and are reached by
an inclined platform up which the gar
bage carts are driven.
PLENTY OF DRAUGHT.
The smokestack, which rises to a
hight of eighty feet. back of the
rear chamber. is four feet in diam
eter and made of sheetiron lined with
tire-brick. The base of the furnace in
the front chamber is made of iron
CRATE bars, but in the second or rear
chamber it is of solid brick. Natural gas
was used as a fuel for some time, but
proved so expensive that coal and wood
have been employed. The furnace is
first brought to high heat by means of a
fire on the CRATE of the front chamber and
little wood in the rear chamber. When
the walls are thoroughly heated the gar
bage is dumped i'll through the holes in
the top and is quickly consumed. With
natural gas as fuel, this furnace has a
capacity OF seventy-tive yards or thirty
tons of garbage day, which is DESTROYED
for about 80 cents yard, or 80 cents ton.
\ furnace of the same type was erected
shortly after that of Pittsburg in Alle-
gheny.
THE COST TWENTY-FIVE CENTS PER
CAPITA ANNUALLY.
1t cost 50, 700, including sheds and plat
forms, and has capacity of thirty tons a
day. The operation in the past has been
so successful that Mayor Kennedy and
Health Superintendent Mclaughlin are
now preparing bill which is intended to
place the collection as well as cremation
of the garbage in the hands of the city
authorities, and these officers have calcu-
lated the probable cost at % cents per
capita annually.
THE BROWN FURNACE.
What is known as the Brown furnace is
now receiving an exhaustive trial in the
yards of the sanitary department of Bos-
ton, Mass. The operation of the furnace
is under the control of the city autEori-
ties, and no definite information has vet
been given out by them, but the follow
ing description, which recently appeared
in the Engineering Record, is known to
be reliable as far as it goes. The furnace
is % feet long, 10 feet wide and about 10
feet high, the interior being divided into
three compartments. The walls and top
are of firebrick Is inches thick, covered
with steel boiler plate. The upper cham
Der is about 20 by by + feet in size, and
has bottom of steel CRATE bars through
which the ashes of the garbage burned in
this chamber fall into the ashpit below.
which is divided into two parts by a
longitudinal wall. The garbage is dumped
on the CRATE through three large circular
holes in the top of the furnace, and is
burned by the flames from a mixture of
steam and oil, as in this city.
POWER.
4 fifteen horsepower boiler is en-
ployed to furnish steam for this purpose
