EXPERIMENT OF interest

Speaker Talks in Telephone Which
Takes His Voice to the Top Of the
Arlington Wireless and Transmits
1t Through the Air to San Fran
cisco-Another Talks to Honolulu.
Theodore n. Vail, President of the
| American Telephone and Telegraph
company, picked up an instrument
from his desk in his office at New
| York Friday afternoon and said in
quite an ordinary tone:
Hello, Carty. This is Vail talk
ing. Can you hear me?"
In the wireless tower of the United
States navy yard at Mare Island.
California, which is in San Francisco
| Bay and something like $500 miles
from New York City, John J. Carty,
| chief engineer of the corporation and
leading scientist in the business Of
communication, caught the voice Of
his friend.
eyes, hear you! This is fine!
This is wonderful" he said.
| Another feat of distance-oblitera-
tion had been accomplished. The
sound of Mr.. Wallis voice had crossed
| the continent, had spanned the thou
sand leagues of farmland. prairie and
1 mountain, almost entirely through
| the air, almost entirely without the
use of wires. The wireless telephone,
Hong sought, had been proved COM
plete success.
Secretary Daniels announced the
successful transmission Of wireless
telephone messages from the United
| States naval radio station at Arling-
ton to the naval radio station ct
Mare Island, Cal, a distance Of about
t2,500 miles. All that was necessary
to carry on this trans-contineutal
! wireless telephone conversation was
to connect the receiver and trans
mitter apparatus of the special tele-
phone outfit with the radio appar-
atus and send the message.
| Captain W. H. G. Bullard, U. S. n,
who is in charge of the Arlington
station, and other officers of the
navy conversed with officers Of the
navy on duty at the Mare Island
yard.
The demonstration was the result
of experiments that have been in pro-
gress for some time, and their success
is expected to have revolutionary
influence on communication between
American naval vessels and shore
stations. By means of this appar-
Iatus, which probably will be install
ed at all naval radio stations, it is
expected that officers Of the navy, on
land, will be able to carry on wire
less telephone conversations with Of
fcers at sea.
Captain Bullard said that the ap-
paratus had been perfected to point
where a person on shore might carry
on a long distance wireless tee
phone conversation with friend on
a transatlantic liner in mid-ocean
whenever shore station and liner
were equipped with the apparatus.
Mr.. Walls words went from his Of
fee o"er a wire to the top of the
United States naval radio tower at
Arlington, Va, which is $50 feet
high. From that point, without in
Eterruption, they leaped into the ether
and sped to the top of the naval
radio station at Mare Island, which
is $50 feet above sea level. There
Mr.. Carty heard them.
1t was more than wireless-tele-
phony test. 1t was test Of wire
then wireless communication.
Had there been a radio tower of
sufficient height in New York City,
the message might have been seat
entirely through the air. But that
would have been easier to do than
what was actually done!
Mr.. Carty's reply to the president
of the company was made over a
Observation-Disclosures there was
no wireless sending apparatus at
Mare Island. If there had been one,
and tower in New York City, the
entire conversation would have been
through the air.
| But-as if TO make the thing more
amazing than it really was-here was
Mr. Vail in New York talking to his
engineer across $500 miles of space
and, the receiving end Of the same
instrument, hearing his reply over
$500 miles of wire.
What a glorious success" ex-
claimed Mr.. Vail, as he listened to
Mr.. Carty's voice II want to con-
graduate you and the others who
have brought it about!" This went
| by wire-and-air.
What next?" answered the engi-
neer. 1--WE can't tell, eh?" This
came by wire.
Mr.. Vail spoke certain sentences
through the air and asked Mr.. Carly
to repeat them, to show he was ac-
tually hearing. To the president Of
! the company, and to a score or so Of
| others who sat close to him, each
with a receiver at his ear, came back
the words. repeated exactly.
There was no doubt that the new
marvel had been wrought success
fully. 1t was the elimination of
| many months Of tests at lesser dis
tances. 1t. became known at the New
York offices of the telephone and tel
egraph company that in August Mr..
Carly had talked with Lieut.. Gran
shaw, an army officer stationed at
Panama, which is 1900 miles away.
The discovery is. of course, Of tre-
mendous significance in the work of
long distance communication. For
instance, it would have been much
easier, it was declared by Mr.. Carty
from San Francisco to have talked
to London, Paris or Berlin than to
talk to San Francisco. Were it not
for the war that very thing would
have been done.
1t will eventually be a very simple
matter. Mr.. Carty said, to call up
friend who is On a ship in mid-ocean
and have conversation with him. =.
And, eventually again, there will
be no place-desert, mountain top,
jungle-which will not have its tele-
phone station. Because the string
ing of wires, Mr. Carty explained, will
not be necessary. The remote ham,
