IEr&L.RsEps STEAM FIRE ESGISE.--A new steam
fire engine, differing in almost every point from all
others within our knowledge, has been lately con-
structed in this city, and been made-the subject OF
several exhibitions in the Park, the last series OF
which have appeared perfectly successful, exhibiting
finely the greatest valuable quality Of such an appa-
ratus-ts untiring perseverance. As originally con-
sructed the steam could be kept up TO the proper
point but rapidly declined whenever tho full power
was applied that It's performance resembed that OF
the usual man.power machines requiring intervals OF
rest. This difficulty has now been overcoe by hKng
CRATE in the furnace addition not previously sup
posed necessary with wood fuel, aud 1t u now able
without any artificial draught, to generate steam as
fast as it consumed, while throwing TO great hight

j. c. f. Larned of this city the inventors OF this
combination the whole of which weighed, before the
crate was added but 500 bs and il designed to be
easily and rapidly hauled in any ordinary condition Of
the streets by horses. without assistance from the
fremen.
The boiler is of course the most important element IN

and when as in the barrel of locomotive boiler the
