following account of the boat, and ofhe stean-enpne
by which II is to be propelled.
Inc Boat has 60 feet keel, feet beam. and is feet

WIN IRON rivets; and the ribs, which foot apart
are STRIPS Oh Sheet iron; which by their peculiar form
are supposed tie possess thrice she strength of the
weight OF iron III the square flat form.
ihe whole weight of iron in the boat, when she shall

tons. Making the whole weight of the Boat and En-

inch IL will have eight horse power and the boiler
Is so formed that the anthrice coal will be used IN

constructed and ITS entire competency for burning the
ousquehanna coal, are entitled particular notice and
Inc inventors, If they succeed in this experiment. will
DC emitted TO The thanks of every PENNSYLVANIA
The boiler constructed as that every part of tIe
receptacle for the fire is surrounded by the water in
tendco 10 be converted into steam and thus the IRON is
preserved from injury by the excessive heat Produced
by the combustion of the coal Its form is cylindrical
IT'S length about six feet and it will be placed upright
m The boat occupying, with tie whole engine not more
than len feet by sic feet.
The engine is nearly completed. The whole cost of
the boat and engine will be three thousand dollars
Atthe place where this work is going on there is n
steam engine IN operation, which was made by NIessrs
webb q Co. and which intended to possess a four
morse power, working two cardipg machines and a
machine for cutting and heading nails and spikes
The boiler constructed for wood as the fuel and the
space occupied by the engine exclusive of the boiler
does not exceed four square feet The simplicity of IFS
,orn and the facility with which it is worked are high
ly gratifying.
In the present state of their operations NIessrs
Webo, Gardner Davis, cannot state with precision
me cost OF their steam engne but they are ds posed to
oeieve, that they can furnish an engine with fen
morse power and therefore sufficient for pair of burr
mil stones OF SIN feet in diameter for fifteen hundred
collars. Should they be able accomplish this steam
engines constructed by them will be in extensive de-
nand-aud the talents and industry OF those gentlemen
VIII be properly rewarded. We cordially wish them
success.
