smokeless steam-G Generating Furnaces

A long account was given in the New
York Herald the other day Of a new
process for the complete combustion Of
fuel, whether wood or coal, for gener-
ating steam This process, the discov-
cry Of Mr. Il, j Mallctt. Jr, the sou

States Consul at Florence, Italy, does
away altogether with the use Of chim-
neys and smoke-stacks, either for draught
or for the voiding of smoke, and is said
to economize the fuel burned to the ex-
tent Of forty per cent. ms compared with,

was taken to keep Oft prying eyes. Sat-
isfed at length that bis discovery was
complete in all its parts and ready to be
brought into public use, number Of en-
gincering experts were invited to witness
the practical workings Of the new fur
mace, which, according TO the Herald,
"promises to work revolution in the
furnishing of power by steam" The
experts, we are told, "came there criti-
cal and doubling, but went away con-

Among tho experts who were present on
the occasion, and to whom the furnace

experimental tests, were Mr.. Blanchard,

fuel is imperfectly consumed and parts
with its residue in smoke and the car
bonic acid gas that is generated in the
process Of combustion. In the new pro-
cess the fuel from the time Of lighting il
until it is reduced to ashes is entirely
smokeless, no mir being admitted into
the ash pit when fresh coal is supplied,
or until the fuel really begins to burn.

readers to give even in q condensed

mace. It is sufficient to say that the first
practical use to which it is to DO put will
be by the Erie Railroad Company. Il
