The saving OF Fuel.

The cost of the fuel annually required in the
United States for mechanical and manufacturing
cannot fall short of fifty millions Of dollars Esti-
mating it at forty millions, inversion or dis
covery which would save one fourth Of this amount
would increase the national wealth by ten millions
of dollars per annum. The cost Of fuel for Gull
naryPurPoses, warming dwellings. &c, is of course
much greater, but we leave that out Of the present
computation.
The immediate saving of expense is but the be-
ginning Of the benefits which such economizing
OF fuel would secure. Many branches Of produc-
tive industry would be largely extended in conse.
quencc of such cheapening Of an important ele-
ment of production. A fabric which cannot be
are required to produce given amount of power
may be produced at living rate when the same
power is obtained from the combustion of thirty
tons. And this is but one of many illustrations OF
far-reaching principle. Hence every plan or in
vention for fuel-saving ia object Of individual
not merely, but Of national and universal concern.
We visited on Saturday the chemical works Of
Alderman d. +. Tiemann Son, Manhattanville,
to witness the operation Of Boxers improved fur
mace, in company with the trustees agent, j.
Amory, esq, OF Boston. Messrs Tiemann & Son
have applied this invention to several different
boilers, SO that it was burning anthracite, btu
mnous, (Liverpool,) and semi bituminous (Dau-
phin) coal in the same establishment at once. In
no case could particle of smoke be seen to issue
from the chimnoy-al was consumed-and only
transparent uncomfortable gases given off through
the chimney, whether high or low. By this con-
sumption Of the smoke it is calculated that saving
of six teen per cent is effected. and much more
bringing the great body Off moro directly in con.
tact herewith. This is effected by means of three
or four peculiarly constructed curved bridges or
arches erected ut certain intervas the spacc
beneath the common cylindrical Cor any other)
boiler, between the fire and the further end, each
bridge or arch reaching up to within three or four
inches Of the boiler and forcing all the heat into
immediate contact Herewith. By the intense heat
tko Re- <>l~ls
through these narrow apertures, consumed,
leaving nothing but incombusble gases to pass off
and up the chimney.
The chief recommendations of this invention are
Its simplicity and chcapnees. 1t may be applied
to any boiler, however odd or imperfect, and the
poorer the boiler ID the greater the margin for saw
ing. No resetting is needed, and the time required
for making the application is very short
number Of certificates were handed us by Mr.
Amory, showing saving of fuel under different
circumstances Of ten. fifteen, twenty five, thirty
seven and as high as SIXTY per cent. by the
was made at the Portsmouth IN H.) Cotton Mills;
sixteen at the Navy Yard Dry Dock. Cbarlestown,
Mass; sixty -one at Hayward & Carncs's works, in
the same town. Thomas Wicksteed, engineer OF
the East London England) Water Works, obtained
but twelve per cent under peculiarly favorable cir
cuinstances; fifteen was secured by Chief Engineer
Haswell at the Z. s. navy yard, Washington, D. C.,
while the careful tests TO which the invention
subjected by the New England Association of Engi-
necrs showed saving of over twenty five per
cent. Messrs Tiemann s. Co. speak warmly in
its favor, and estimate their saving by it at twenty
five to thirty per cent, though we do not remcm-
Der that any precise tests OF it's value have been
applied by them during the brief time they have
had il in operation. But we do not propose to de-
termine the exact amount Of saving effected by
this invention, nor to institute comparisons be-
tween it's merits and those of others with which it
may be brought in competition. Though the saw
ing were but ten per cent, it would be richly worth
effectng, especially since little trouble or cost
is involved in its application Messrs. Stillman,
Allen & Co., at the Novelty Works, arc the agents
for this city, and we advise those interested in
fuel saving to examine this furnace, compare it
with others, and judge whether they can afford to
do without it-Ntu York Tribune.
