WIRELESS TELEPHONE.
In tho "Noisy NoiseIess Court" q
Worlds Fair Marvel.


For some inexplicable reason an
epoch-making novelty at the ST. Louis
exposition that promises to rival the
much -heralded air-ship competition has
been almost entirely overlooked. Prof.
Goldsborough, chief Of the department
Of electricity, has quietly prepared
wireless telephone exhibition that will
give the blase wonder-ignoring Amer
ican sight-seer a very agreeable shock
of surprise. The telephone, then in its
first stage of development, made men,
orable the Centennial exhibition in 1876.
If the air-ship competition material
ICES it will have to share with the
NOISY Noiseless Court" the historic
honors at st. Louis. In the quadrangle
or court formed by the four walls Of
the Palace Of Electricity, the visitor
may experience the sensation Of hear
ing sounds at distance, without any
visible medium Of communication. Co
ing into the court one hears, no other
sounds than the nearby buzz Of the
throng and hum Of moving machinery.
To all intents and purposes the court
is literally noiseIess, yet the air Is
fairly ringing with the music Of the
bands in the faraway bandstands, the
music Of monographs in distant booths.
The visitor is simply mystified on put
ting to his ear pair Of ear-pieces re-
sembling the watch-case receivers that
are worn by the telephone girl during
her switchboard duties. The weird
sounds that become audible are as
disconcerting to the twentieth century
man accustomed to talking machines
and long distance telephones as were
Stanley's electric shocks to the abo-
rhymes Of Africa.
Mr. H. R. Hutchison, who has been
experimenting for several years along
the line of wireless telephony, has now
perfected his apparatus to such an ex-
tent as to make 1t serviceable over
considerable distances, though yet at
considerably less than a mile. When 1t
is remembered that the first telephone
circuit was only few yards long, and
the radius Of the first wireless telegra-
ply transmission was circumscribed
by the walls Of laboratory, the pres
ent limitations of wireless telephony
are really not significant.
The Worlds Fair transmitting or
sending station is located at Block %,
Palace Of Electricity. 1t consists OF
large graphophone and one Of Mr..
Hutchison's heavy current transmit
ters. This transmitter is in itself
marvel, as it operates with current
of fifteen amperes, which would OF
course destroy an ordinary carbon
transmitter. Such a heavy current
necessarily generates considerable heat,
so that provisions for water-cooling
the apparatus are necessary. Connect
ed to the transmitter is a large coil
buried in the ground Of the court. The
receivers consist of two ordinary watch
case telephone receivers, attached to
conducting spring supports, which pass
through handles, terminating in an
attuned receiving coil, about foot IN
diameter, but about two inches In
width and very light, so that 1t can be
held with ease by means Of the ham
die provided. This coil responds to the
invisible electric radiations emanating
from the transmitting apparatus, in
ducing similar electric pulses In the
ear receivers, thus reproducing the ex-
act sounds.-Philadelph Record.
