| If you want to see what the world is
| really doing, come to the st. Louis expo
| sition. The latest inventions along every
| line are shown here. This is twentieth
| century fair. and it has all sorts of new
twentieth century machinery. 1 have spent
| today in the great palace of electricity,
| talking with Prof. Goldsborough, who has
charge of the electrical department l have
watched girls cooking with lightning and
smoothing boiled shirts with electric irons.
L have seen men healing diseases with
electric sparks, telegraphing a thousand
words a minute, telephoning without wires
and even without the aid Of the hello
girl"
Yes! Actually telephoning without the
intervention of her nasal twang and with
out the danger of her pink ears hearing the
secrets they transmit. They make their
own connections and talk as long as they
please, Embossed by her majesty.
In my talk with Prof Goldsborough 1
asked him about these automatic tele-
phones. Said he:
we have three different stystems ex
hfbited here. The Stronger system has
Deen IN process of development for num-
Der of years, but it has only recently he
come thoroughly commercial, and it is now
extensively used in the factory towns about
Boston and Chicago. We have it here in
the electricity building and use it in our
business. The exchange is so arranged as
to show the working of about ten thou
sand telephones. We have telephones at
each of the various entrances of this build
ing, IN our offices, in the laboratory Of the
national bureau of standards and other
where's. The system gives us a means of
secret communication with one another the
central operator being eliminated. We can

cally impossible for any one else to know
what goes on.
The Automatic Telephone.
"In addition to this" continued Prof
Goldsborough, eve have the Faller auto
matte telephone system, which has been so
developed that it is now ready for CONNER
cial application on a large scale, and also
the automatic telephone of the Bell COM
pany. The Belle Telephone Company has
been quietly perfecting such machines for
several years, and they have their apparatus
now on view in section II of this building
This is practically the first announcement
that has been made of it and 1t is one of
our most important novelties.
will such telephones come into general
use?"
'I believe that they will be used at first
in small installations said Professor
Goldsborough. 1T may take some time to
adapt them to the cities or to make 1t pos
sible that they should take care of the enor-
nous traffic of large city without the use
OF operators That is matter of gradual
development, and 1T involves serious ensl-
neering problems"
"Then we shall have operators for some
time YETI"
ct think So" was the reply. 1--WE still use
tallow candles, gas lamps and coai OH; az
though we have the electric light which
excels them as an illuminant. 1t is not pos
sible to say as yet that the automatic teie-
phone will do away. completely with the
central station telephone.
Talking Without Wires.
GLOW about the wireless telephone?"
"That Is a new invention which is shown
In a comprehensive way and on a sound
engineering basis for the first time at this
exposition. You can see 1t In the Palace
OF Electricity and listen to the TRANSMISSION
of articulate speech without wires Prior
to this demonstra tons have been enectsd
where the ground or currents of water
have been used as means or per1ectlns
the circuit between the instruments: mere
at the exposition we have an absolute oi-
vorcement of the transmitting ana recelv
ing Instruments one from the other, with
cut any physical connection whatsoever
A person, equipped with one or these teie
phone transmitters and the coll attached
thereto can pass freely through the court
and central aisles Of this great building
and distinctly hear the words spoken AT
the transmitting station, which is entirely
out of view and far beyond ear range.
The intent of this demonstration is TO con-
clrsiyeIy prove that the connection is ap-
solutely wireless We can easily show the
general public that wireless telephone sta
tions are installed and in operation, but 1t
IS difficult to make many believe that there
Is not some means of TRANSMISSION petWeen
the stations. You can easily see that Tn s
could not be the case with the wireless
telephone system exhibited here, as the per
son having the receiving apparatus In
hand knows that 1t Is entirely free from
any outside connection.
ssrThen the only use of this Invention Is 10
listen to some central speaker or 10 talh
between man and man?'
$50 far the system Is used here only as a
means of enabling one speaker to tax 10 a
large number of listeners. Whether IL VIII
ever have a commercial value remains 10 De

address through one of these machines ana

ough?" asked.

be perfectly feasible to install such an APP

ments which would be valueless In connec-

ton"
