ELECTRO MAGNETISM AS A MOTIVE
PowER4THE QUESTION SETTLED
Professor Psge, in lhc Lectures which b.
is now delivering before the Smilhsonior
Institution, states that here is no, long e
any doubt Of the application Of this power a.
Ia substitute for sleam, He exhibited lb,
most imposing experiments ever witnessed
lin this tranch Of science. An immense bal
LOT Iron, weighing one hundred and sixiJ
pounds, was made 10 spring up BY magnetic
action, and 70 move rapidly up and down
dancing like a feather in the air, without any
Visabie support, Tie force operating upor
lhe bar, be slated % average three kandrsl
pounds through ten inches Of its notion
| He said he could taise ibis bar one hundred
feet rs readily as through ten inches, apd be
expected no difficulty in doing the same with
bar weighing nston, or a hundred tons =
lie could make pile driver, or a forge
ha"mer, with gruat simplicity, and conk.
make an engine with stroke ofsix, tyselY e
twenty, or any number of feet.H sagi ia7.r
The most beaalful experiment we ever
Witnessed was the loud sound and brilliant
fash from The galsanic spark, when produced
near certain point in his great magnet.--
Each snap was as loud as o pistol; aud when
he produced the same spark al little diss
tnnce from this point, il made no noise at all.
This ,,ecent discovery is said 10 have .prac,
tical bearing upon the construction ofan elec.
tro-magnetic engine. Truly great power
is heIe; and where is the limit 10 il?
He then exhibited his engine of between
four and five horse power, operated BY bat.
terry contained within a space ofthree cubic
feet. 1t looked very unlike magnetic mas
chine. II was a reciproca,ing engine Of
TWO feet stroke, and the whole engine and
battery weighed about one ton. When the
power was thrown on by the moliOn of q
lever, tho engine started off magnIficcnily,
making one hundred and fourteen strokes
per minute; though, when il drove circular
saw ten inches in diameter, saving up boards
an inch and quarter thick into Iaths, The
engine made but about eighty strokes per
minute rs.jl1s,4# ez E4ttE 3tlsIrE ,tH

mechanical triumph. The force operating
aponl This great cylinder throughout the whole
motion of Two fee', was stated to be six hnn
died poun Is when the engine was moving
slowly; but he bad not been able to ascertain
what the force was when the engine was
running at working speed, though i, was
considerably less. The mpst mportan, and
interesting point, however, is The expense o!
the powef. Professor Page stated that he
had reduced the cost so far, that ii was less
than steam under many and most conditions
though not so low as the cheapest steam en-.
gines. With all the impcrfections Of the
engines, the consumption of three pounds
OF zinc per day would produce one horse
power. The larger CONTRARY to what has
been known before the greatef the ecano.
my. Professor Page was himself surprised
at the result. They we're yet practical diff
culies to be overcome; The battery had ye
TO be improved, and it remained ye, 10 II,
the experiment on agrander scale, to max,
a power Of one hundred horse, or more.
Truly the age is fraught with wonders, an
we can nov look forward with certainty /
the time when coal will be put to better us
I than 10 burn, scald and DESTROY. ,i'a' y
