the reverse operation--that is TO say,
the reeonversion OF electricity into me-
chanical power. The tolemachon con.

armatur0. This field OF force consists
of twelve large electro-magnets in two
sets of six each, the poles Of each sot
facing each other and connected 10.

parallel with them, in the armaiure AK
Is supporting an armature consisting OF
ring OF iron wire serving as n core,
around which ia wound an insulated
copper wire in two series bf 90 coils.
The end Of these wires como out al
ternately to the right and left Of the ar.
mature, and are connected with two
break pieces upon their axis. Six
springs, or brushes of copper wire,
press upon theee break pieces, each
pair OF brushes facing each other aud
opposite pair of magnets in tho field
OF force. The electric current enter.
ing tho machine presses round the field
and magetizes tho magnets. At the
same time il passes through the arma-
ture, magnetizing that, so that tho poles
OF the armature nearest 10 the poles OF
the field magnets are of tho opposite
name. In consequence OF this the field Of
force magnets attract the poles OF the
armature and cause the armature TO 70.
yolye. Bat the motion in It's new posi-
ton brings other portions Of the break
pieces in contact with the spring and
causes n redistribution of the magnet
ism. Again, attraction takes place as
before. and again the direction OF the
current is changed by the break pieces.
The magnetic effect being continuous,
the rotation is continuous, increasing
constantly in speed until tho fric.
ton and the magnetic power balance
each other.
In Sundays experiment the hodeme-
ter showed that tho machine male 900
revolutions minute.
The electricity from the wonderful
telemachon may be applied 20 illumin
alton. II solves the problem OF the
subdivision of electric lights. Both
the Wallace foundry and the Farrell
foundry, near by. are lighted by these
lights, the army Of mon being formed
in two divisions, one working during
the day and tho other up TO midnight.
Thickly stnddied as these foundries are
with heavy machinery, and obstrueted
as tho light must necessarily be by the
ponderons cranes, drills, supporting
columns, and projections, a clear light
is thrown upon the machinery, perfect
ly Illuminating it. Adjustments 10 the
thirty-second Of an inch may be made
without the least strain upon the eyes.
A beautiful effect OF this light Is its
polarization-that mottled appearance
which il assumes when falling
through glass This is tho only artifi-
eial light, il is said, that is capable of
producing it.
The following is an estimate made
by an expert of what it would cost to
light the streets OF New York with
these lights: Tho average street burn
eF gives light equal TO ten candles.
Assuming that one of the eight
electric lights produced by the power
Of one machine Is equal to 4 900 candles,
and assuming that there are 5000
lamps, each burning 20 cubic feet OF
gas an hour, ut q cost Of 81 thousand
feet, it would require I2% OF these
machines 10 furnish all the light requir-
ed. The cost Of the gas Mt this rough
estimate would be 800 an hour. To
produce the same light by electricity
would require. say, thirteen machines
placed upon towers. The cost Of a
single light equal TO that of 900 can
dies would be three cents an hour.
Each machine giving 1000 candle lights
would cost, therefore, twelve cents an
hour, and thirteen would cost 81 SO an
hour.
The things that he had seen in the
foundry had curious effect upon Mr..
Edison. He seemed wrapped in
thought. Owing to his deafness the
many jokes made by his friends, Profs.
Barker and Chandler. were lost upon
him. Occasionally they were repeated
to him by Mr. Bachelor. When Edison
hears good joke he seems to stop the
great thinking machine constantly
working within him. He laughs heart
lily, and then forgets his surroundings,
and relapses again into deep medita-
ton. hr. Wallace was explaining an
instrument he has invented that will
throw small stream OF wafer
with such force as TO tear the flesh from
the hand. "Barky," said Edison sud-
denly, eff person should cut a
mans throat with such stream
of water, I don't believe jury could
be found that would convict him OF
murder.
While going from the works, Mr..
Edison saw a large iron caldron.
He stopped, looked at it meditative-
ly, and then said: "rhat reminds
me of what the Jersey mosquitoes can
dor
"Oh, yes' said Prof. Barker, ''tell
us those mosquito stories of yours, Ed
ison."
II know two OF them, returned Edi
son. "a Jerseyman was so troubled
with mosquitoes one night that he went
down into the yard and crawled into q
huge iron caldron. Well, pretty soor
he heard noise as If boaring was
going on. He found they were boar
ing through the caldron with their
bills. When they had accomplished this
the man got big stone and clinched
their bills"
"Well. said one of the party. what
then ?"
"Why," answered Edison, sthe
mosquitoes flew away with the cal
drcn."
''The next story he went on, '.it
about drunken man in Paterson, who
lay down BY the roadside one Sunday
and went to sleep. While in this posi-
tion Jersey mosquito alighted upo1
him, and q Jersey policeman coming
along arrested the mosquito for open.
