Telephone President Talks
to San Francisco, Cal.

New York.-Theodore N. Vail, pres
ident OF the American Telephone &
Telegraph company, picked up an in
strument from his desk in his office
at 10 Dey street Wednesday afternoon
and said in quite an ordinary tone:
Hello, Carly. This is Vail talking.
Can you hear me?"
In the wireless tower of the United
States navy yard at Mare Island, Cal,
which is in San Francisco bay, and
something like 5000 miles from here,
John ]. Carly, chief engineer of the
corporation and leading scientist in
the business of communication,
caught the voice of his friend
Yes, hear you! This is fine! This
Is wonderful" he said.
Another feat of distance oblitera-
ton had been accomplished. The
sound of Wallis voice had crossed the
continent, had spanned the thousand
leagues of farm land, prairie and
mountain, almost entirely through the
air, almost entirely without the use
Of wires. The wireless telephone, long
sought, had been proved a complete
success.
Wallis words went from his office
over a wire, to the top of the United
States naval radio tower at Arlington,
Va, which is $50 feet high. From
that point, without interruption, they
leaped into the air and sped to the
top Of the naval radio station at Mare
Island, which is $50 feet above sea
level. There Carly heard them.
It was more than a wireless tele-
phone test. 1t was a test of wire, then
wireless communication.
Had there been a radio tower of
sufficient height in New York City,
the message might have been sent en-
tirely through the air. But that would
have been easier to do than what &C.
tually was done.
Carty's reply to the president of the
company was made over a wire tele-
phone, because there was no wireless
sending apparatus at Mare Island. II
there had been one, and tower here,
the entire conversation would have
been through the air.
amazing than it really was-here was
Vail in New York talking to his en-
gineer across 5000 miles of space,
and the receiving end of the home in
strument hearing his reply over 5000
miles of wire. ....
What a glorious SUGGEST" ex-
claimed Vail as he listened to Carty's
voice. Il want to congratulate 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.
Vail spoke certain sentences
through the air and asked Carly to
repeat them to show he was actually
hearing. To the president of the com
pany and to a score or so of others
who sat close to him, each with a re.
ceiver 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
AuOiIHo vi lSSbS dJ ISSSer Instances. 1t
became known at the New York Of
fices Of the telephone and telegraph
company that in August Carly had
talked with Lieut. Cranshaw, an army
officer stationed at Panama, which is
1900 miles away.
The discovery is of tremendous sig
nificance in the work of long-distance
communication. For instance, it
would have been much easier, it was
declared by Carly from San Fan
cisco, to have talked to London, Paris
or Berlin than to talk to San Fran.
cisco. Were it not for the war that
very thing might have been done.
1t will eventually be very simple
matter, Carly said, to cali up a friend
who is on ship in midocean and
have a conversation with him. And,
eventually, again, there will be no
place-desert, mountain top, Jungle
which will not have it's telephone sta.
ton, because the stringing Of wires,
Carly explained, will not be neces.
sary. The remotest hamlet will sim.
ply have its wireless telephone.
