! W Washington, Sept. 29.-Long distance
! wireless telephone communication was
/ accomplished for the first time today,
! when experiments extending over sew
eral months eliminated in successful
/ TRANSMISSION OF the human voice by
radio from the great naval plant at
( Arlington, Va, across the continent TO
| the station at Mare Island Cal $500
miles away
The experiments were conducted IN
! der direction Of Capt. Bullard chief Of
! the navy's radio service. in co-opera-
ton with the American Telephone d
/ Telegraph Co, and the Western Elec-
trlC Co. Secretary Daniels. announcing
+ The result tonight. predicted that fur
! ther development Of wireless telephony
would make great changes il long dis
tance communication both for military
and naval service in commercial usage.
| Successful operation Of a device for
! automatically transferring to the ra-
! dio telephone conversations original
! ing on metallic circuits also was ac-
comphshed il today's tests. President
| Theodore n. Vail and other officials of
| the American Telephone & Telegraph
! Co. at New York talked easily with
/ the Mare Island station. the converse
ton travelling over an ordinary metal
( lie line from New York 10 Arlington
and thence by radio across the CONT
nan;
THE fact that the voices can be
started on land wire and automatic
ally transmitted TO voice radio
transmitter said Secretary Daniels.
holds out hope that persons on land
should readily he pat in touch with
others at sea through some central
transmitting station"
Navy Dept Announcement
/ The navy department formal
nouncement follows
/ Secretary Daniels is pleased to
nounce the successful outcome Of expert
ments which have been carried OF for
/ the last few months by the American Tel
/ ephone & Telegraph Co. and Western
/ Electric Co.. in cooperation with radio
/ stations under jurisdiction OF the navy
department. by which long distance
wireless telephony has been made pos
! sible.
To-day. Sept. 18th, speech was sue
cessfully transmitted from the Arlington
radio station TO the radio station at Mare
Island, California, and there successfully
received, thus making possible converse
ton without wires over distance of ap-
proximately $500 miles, the first time this
great distance has been covered by wire
less telephony. In the first experiment
today the voice was successfully trans
mitted by radio TO Mare Island from Ar
lington, the return answers and commu-
nications being made over the trans
continental land telephone line This
was successfully accomplished III the
presence of officials and engineers OF the1
Western Electric Co., representative OF
the signal corps of the army, representa-
tives Of the technical and operating de-
partments of the navy department and
few other interested parties.
After this successful demonstration
conversation originating in New York
was transmitted over the land line to
Arlington there automatically connected
to the radio transmitter which carried
the voice to Mare Island. where it was
clearly and distinctly received and an
swers and other conversations were from
there transmitted over the trans-contl-
mental line to the orig1na ting ofilce In
New York.
1.-THE conversation was carried on by
the president of the A T. & T. Co, Mr..
vail. the vice president. Mr. Bethel. and
Mr. Walter Bury, one Of the directors.
while at Mare Island were officials OF the
navy department, Mr.. John j. Carly,
chief engineer of the A. T. & T. Co., and
representatives of the Western Electric
Co. Every official taking part in this
demonstration is enthusiastic about the
results and the possibility OF developing
this system as an extension Of the tele-
phone system to ships at sea.
THE use of such long distance wireless
telephone communication in naval or mil |
itary operations is still in an undevel-
oped state, but it is expected valuable
use can be made of this wonderful dem
onsrration. but aside from such consid- |
Grafton the department and its officials |
may well feel proud that they have been
interested co-operators in the first practi- |
cal developments of this latest march I
in the wonderful science of radio COM /
munication"
