STEAM BOATS.

N Steam Boats. have caused deep and general
,mpressiou of the necessity Of guarding against
their repetition. The bursting Of the boilers is
one Of the most common and fatal causes The
attention OF Mechanics is turning more aud more
towards this subiect-and IN the course OF lew
,ays, notices have been taken Of severa schemes
which have been projected. One OF them Is 10
lower the fire from the boiler IN case oil danger
another proposes to give some signal oy the ma
chipery to warn against approaching INJURY
But new scheme has been starteu In baltimore
,lenoninated a Wonderful discovery IN Me-
cbooics. or the "Wonderful Lever" which is
intended to supersede steam, and to move boat
Inv the mere efficacy of a new Lever. A cores
5noodent OF the Baltimore American gives the iol-
iovino account of it-Our readers must Judge tor
themselves of its feasibility. -Richmond CON-

feet of space in the wheel.
The opinion of The best informed pei sons is that
this invention will BY It's r,eat advantages and its
great economy, prove a certain and rapid growth
in navigation. In fact vessel will cost three
times les. In building A vessel of any size can
sail ON the open seas or in rivers without any
other aid than this lever. One wheel placed with
in the vessel is enough. 4 power sufficient to
keep up the motion Of the wheel is enough. The
greatest power is in the wheel, and this force is
equal to one hundred horse power A voyage to
Europe will be completed in Is or Is days with
out anv risk except that Of coming in contact with
another vessel. rocks, or lightning, aud can navi-
gate in all seasons.
