ton was accomplished TOT the hiS'
time Yesterday when experiments
extending over several months' cur
minated in successful TRANSMISSION
of the human voice by radio frori
the great naval Plant at Arlington
pa across the continent to the sta
ton of Mare Island, Cal, z'ooV
miles away.
The experiments were conductcu
under direction of Captain Bullard'
Chief of the navy's radio service, IN
co-operation with the American Tel
ephone and Telegraph Company ana
the Western Electric Company. sec
rotary Daniels. announcing the result
tonight, predicted that further ue-
xaIopment of wireless telephone
r would make great changes In long
distance communication both lor
military and for naval service ana
commercial usage.
Successful operation of a device
Y for automatically transferring TO the
radio telephone conversations origi-
mating on metallic circuits also was
accomplished in to-day's tests. Pres
ident Theodore N. Vail and other Of
q ficials of the American Telephone
' and Telegraph Company at New
York. talked easily with the Mare
Island Station, the conversation
travelling over an ordinary metaihe
line from New York to Arlington
X and thence by radio across the con-
tinent.
''The fact that the voices can be
started on a land wire and automat-
ically transmitted to wireless
transmitter," said Secretary Daniels,
holds out hope that persons inland
should readily be put in touch by
telephone with others at sea through
some central transmitting station"
The Navy Departments formal
announcement follows:
Secretary Daniels is pleased to
announce the successful outcome OF
experiments which have been carried
ON for the last few months by the
American Telephone and Telegraph
Company and Western Electric Com
pany in cooperation with radio sta
lions under jurisdiction of the Navy
Department by which long-distance
wireless telephony has been made
possible.
Yesterday, September 30, speech
was successfully transmitted from
the Arlington radio station to the
radio station at Mare Island. Califor-
mia, and there successfully received,
thus making possible conversation
without wires over distance of ap-
proximately $500 miles, the first
time this great distance has been
covered by wireless telephony.
y "In the first experiments to-day
the voice was successfully transmit
ted by radio to Mare Iseland from
Arlington, the return answers and
communications being made over the
transcontinental land telephone line
This was successfully accomplished
in the presence of oricials and en-
gineers of the Western Electric Com
pany, a representative of the Signal
Corps of the army, representatives
of the technical and operating
departments of the Navy Depart
ment and few other interested
parties.
after this successful demonstra-
ton conversation originating in New
York was transmitted over the land
line to Arlington, there automatical-
ly connected to the radio transmit
ter, which carried the voice to Mare
Island. where 1t was clearly and dis
tinctly received and answers and
other conversation were from there
transmitted over the transcontinen-
tai line to the originating Office in
New York.
The conversation was carried on
by the President of the American
Telephone and Telegraph Company,
Mr.. Vail the Vice President, Mr.
F.. Bethel. and Mr.. Waterbury, one of
the Directors, while at Mare Island
were officers of the Navy Depart
ment. Mr. John j. Carly. Chief En-
gineer OF the A. T. and T. Company
and representatives of the Western
Electric Company. Every Official Ia
king part in this demonstration is
enthusiastic about the results and
TIE possibility Of developing this sys-
tenn as an extension OF the telephone
system to ships at sea.
1.-THE use of such long-distancc
wireless telephone communication Ia
naval or military operations is still
in an undeveloped state, but It is ex-
