| WHAT MAY BE DONE WITH 4 HORSESHOE
MAGNET AND A sHINGLE NAIL.
From the Rochester Democrat and Chronicle.
Gary has shown that magnetism Is
| dynamic rather than static. lie demon
strates this by the use of Il common horse
| shoe magnet and a shingle nail. His
statement of the discovery is this: Il


have discovered that 4 straight piece OF


iron placed across the poles OF 4 magnet,
and near to their end, changes its polar
ity while in the magnetic field. and before


it comes in contact with the magnet,
the tact being, however, that actual con-
tact is guarded against. The conditions
are that the thickness of the iron must


be proportioned to the power OF the


magnet, and that the neutral line or lines


OF change in the polarity of the iron is
nearer or more distant from the magnet
according to the power of the latter and
the thickness OF the former. My whole
discovery is based upon this change in
the polarity of the iron, with or without a
battery" This paper has commented
on this wonderful discovery from time 10
time. A descriptive article in the March
Hdrper'S attracts us again to the subject.


The importance of this discovery can


not be overestmated. 1t introduces mo-
tive power in all the arts and industries.
The man of the future may own his loco
motive and journey from place to place
without paying hostlers or railway cor
porations. Watches, sewing machines.
Illuminating machines, tramps, news
papers, dispatches, mails. ct cetera, ct
ceterorum, will all pay Difference to the
motor OF the future. Hitherto the chief
difficulty has been that in order to secure
the revolution OF the armature, or piece


oil soft iron connecting the poles OF a
horseshoe magnet, steam engines were
employed TO set the armature in motion.
The principle of the neutral line within
which tie armature changes its polarity,
and with the charge of polarity sets up
a limited motion, does away with the
necessity of a motor, since, gwen mag
net and armature and electricity and
motion are generated. The simple state
ment of this discovery suggests its infinite
dynamic possibilities. Every time Gary's
aimature-which is coiled with wire
crosses the line of polaric change. it pro-
duces a spark of electricity. and as the
armature is wholly under the influence of
the magnet, it can readily be seen that
electricity Tor Illuminating power can be
secured by the automatic action of the
forces of nature. This simplifies the
problem OF cheap Illuminating. Given
the selfregulating, seli-generating motor,
the division of the electricity, and you
have the cheapest kind of light fer the
millions.


1t is fortunate at this time when the
vast west is beckoning the millions to
her fertile bosom, and provoking capital
TO the construction OF railways that this
simple principle has been discovered.
In the present methods of locomotion a
great amount OF energy is expended in
carrying fuel, engines must be construct
ed in the heaviest fashion, steamers are
handicapped by the weight of coal here
alter what is more important, our fuel
supply can be devoted 10 pure domestic
purposes and must be cheaper than it
now holds. The dream OF perpetual
motion, under the given circumstances,
is realized, and with it train of conse-
quences, which has hitherto visited only the
enthusiast in his midnight toiling over
the ever-illusive problem, consequences
which, though never so desirable, have
been regarded by the world as utterly
unattainable and fit only for derision.
Mr.. Gary's working model is said TO de
monstrate all these possibilities. In order
10 accomplish the heaviest work, one has
only to add TO the size of his magnet and
armature.
