Because of the light it throws up
on business revival in the United
! States during the latter half OF
1915, the development of the coast
! forecast telephone system, the extra
ordinary achievements in wireless
telephony, and the cooperation be-
tween its experts and representatives.
oil the ARMY and Navy departments
for providing the Government for
| use in national defense an unequall-
ed system of quick communication
between different sections of the
country, the disclosures of this years
report of the American Telephone
| ard Telegraph Company have un-
usual interest. Theodore N. Vail,
tpYesident of the company,speaksc con-
, fnently of the outlook and declares
/, that the company, and it's associated
companies, were never in a more sat
isfactory position-fnancially physi-
cally, and in their relation to the
public and their employes-than
they are today.
With the extension Of the Tex
treme distance transmission" into all
States of the Union, it is now pos
sible to talk from any State to some
points in any other State, while over
a vast territory covered by the Bell
System, it is possible for any SUBJ
scfiber to talk with any other sub
scriber regardless of distance. In
this way the effective talking range
of every subscribers station in the
Bell System has been extended with
in the year, and the usefulness of
the whole service increased.
The company added l,O29,951
mileage during the year, bringing
the total mileage up to 18,5O5,545
miles. Ninety-three per cent. of the
total mileage represents copper wire,
the company maintaining 10,536,837
miles of underground wire, the I'M
derground plants alone representing
a cost of 205,700,000.
Through the means of radio or
wireless telephony the company's en-
gineers have during the year materi-
ally extended the area upon the
earth's surface over which the tones
OF the human voice may be transmit
ted; In consequence of these ad-
vaHces, speech was transmitted on
April 4th from a radio station at
Montauk Point, Long Island, to Will
m1ngton, Del. On August 27 with
the company's instruments installed
with the permission of the Navy De-
paTtment at the Arlington, Virginia,
radio station, speech was transmitted
from Arlington, Va, to the Mare Is
land Navy Yard, California.
On September 29 speech was
transmitted by wire from the COM
pany's head Office at Is Dey street,
New York city, to the radio station
at Arlington, Va, and thence by ra-
dioI or wireless telephony across the
continent to the radio station at the
Mare Island Navy Yard, California.
The following day-September 30
wireless telephone communication
was established between Arlington,
Virginia, and Pearl Harbor in the
GElshiaa Islands, where the Com
pany's engineer in company with
United States naval officers, distinct
ly heard words spoken into the ap-
paratus at Arlington.
On October % speech was success
fully transmitted across the Atlantic
Ocean to the Eiffel Tower in Paris,
where the company's engineers in
company with French military Off
GERS heard the words spoken at Ar
hngton. While this conversation
was being carried on between Ar
ington and Paris, the company's
representatives at Pearl Harbor, Ha-
waii, together with an officer of the
United States Navy, heard the words
spoken from Arlington to Paris.
These experiments were extremely
valuable, but it was evident that the
true place of the wireless telephone,
when perfected, will be for use sup
Elementary to and in cooperation
with. the wire system and not antag-
onistic to 1t, or displacing it.
