to San Francisco, Cal.

New York.-Theodore \. 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 ike 5000 miles from here.
John J. 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 Walls 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 wire. to the top of the United
States naval radio tower at Arlington.
Va, which is $50 feet high. From
tina. point, without interruption. they
leaped into the air and sped to the
top OF the naval radio station al Mare
Island. which is $50 feet above sea
level There Carly heard them
II was more than a wireless tele-
phone test. 1t was test OF wire, then
wireless communication.
Had there been radio tower of
sufficient height in New York City,
the message ght 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 a tower here,
the entire conversation would have
peeH through Tue air.
But-as If TO make the thing more
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.

voice. Il want 10 congratulate yoa

What next" answered the engi-
neer. 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

words, repeated exactly

months Of tests at lesser distances II
became known at the New York Of
fees Of the telephone and telegraph
company that in August Carly had
talked with Lieut.. Cranahaw, an army
officer stationed at Panama. which IS
$500 miles away.
The discovery is Of tremendous sig-
nificance in the work of long distance
communication. For instance. il
