TBE NTw PERPETUAL MoTIoS-There stands on
n table at No sos Broadway, an innocent-lookiag
machine consisting mainly Of two brass wheels geared
together moderately but continuously revolving with
oct the visible expenditure OF any power The smaer
gear wheel between one and two inches in diameter,
j. mounted on vertical axis and IL stesdied by
small Ay.wheel. This makes some 50 revolutions per
minute and gears into another some ten times larger,
which latter is fixed shaft inclined toward the
first some ftcen degrees from the perpendicular.
This wheel carries delicstely mounted on it, upper
surface two heavy bars of brass, extending dsmet-
really across at right angles TO each other. a small
wheel on the quick shaft in contact with the
ends these bars they pass and continually thrusts
them over toward the highest SIDE What We have
termed bars much larger at the ends than st the
middle and in fact weights connected bya wire;
bu, the effect is the same, and the increased weight
on the side which is descending apparently causes aud
maintains the motion Of the whole. The glass cover
ing was partially removed and the machine was
stoned in our prcsencc-the second time only,
We are assured, for several weeks-blt it slowly
started again when released in suitable position for
gravity to act fayorably on the bars and attained
its ordinary speed.
A perpetual motion of the character which this
q,pcars TO be is simply impossible. The difficulty of
solving the riddle however, renders it most interest,
ing object for study, and we recommend 1t to the atten
ton of the curious The machine is an importation

les and sarans of various grades in that favored city,
certify strongly to their belief in its genuine character.

the existence Of secret band, which, mpeled by
suitable means outside the room, might be connected
to one of the shafts of the machine at point con-
ceaed within bearing. Backed up by the audience,

other In the machine now under notice both shaft,
are dclicatey supported both at top and bottom on
thin discs of transparent glass thus eectuay cutting
off any mechanical assistance through these avenues
and the nonconductng property of this material
tends to shut the months of those superficial phoso
pliers who are always ready to explain everything UNI
usual by simply pronounsing the words "snrna mag
netsm" or electricity
Our solution Of the phenomenon consists in suppos-
ing the large wheel, likely the crossed bars
supported thereon, to contain iron at one or more
points This wheel in very close proximity
to two wooden posts in the framing, one or both
Of which posts we conceive TO conceal iron bars,
which Inter become magnets at regular In
tervals The magnetism Is induced either directly
or inductivey, by the aid OF a battery or re-
volvDg armature, located outside the room, and
connected through the legs of the table. The fluid
operates in the ordinary manner, by heca coil, the
period of the current being regulated by clock work
As the iron in the wheel approaches the post the iron
therein becomes magnet and attracts it, but as it
reaches the nearest point the current is suspended,
and the magnetism disappears. Should the wheel
turn too fast the magnetism does not cease in time,
and by operating slight retard after the point is
passed soon brings it back to its favorte velocity
This theory explains both the existence and the regH
lariy Gifts notion and correct leaves che apparatus
possessing a very moderate degree Of interest az
feeble magnetic engine.
The BOYS IN HCRRY-TnE KITE SEAsoS.-
These warm, pleasant days which produce results
boys with great gee the sunny prophets of the com
ing Summer Anxious to begin their warm-weather
udoor sports the youngsters watch oyfuy the dsap
pearance of the pis from the play grounds and
thank their lucky stars that no uolucky chance has
given Commissioner Eblng dominion also over the
fields. and that they will not have to wait for July
sun to dsspate into muddy nastness any mountainous
ice monuments of his ingenious miscalouation.

But some of the ambitious ones, hoping more than
adult mortas dare and putting more trust in the sun

acs OF wisdom, have already brought out their mid
summer sportive implements and are forestallng the
season by flying kites and playing ball A couple of
brave little cold.fngered fellows were last evening
INDUCING in an ofssason game Of marbles under
shelter of the Brick Church fence. Although the
water effaced the ring about in two minutes and
they had to "knuckle down 4" with their fingers on
the lee they persevered notwithstanding to cheat
Themselves into the idea than il was fan.
The ballplayers are few. There Is occasionally
little game Of "catch," or a frozen two-hsnded at
tempt at "barnbal," but they generally end in the
thorough soaking Of the ball and the total disoom
future of the juveniles; and not until the Summer sun
has thGwed the atmosphere and dried the meadows
will there be any hearty, old-fashioned games Of
"base" and "two-old-cat.'
But these light winds are just the thing for the
kites and the young gentlemen Of the second class in
spelling, know that quite well as the wise editors
