Joint use of the telephone and radio
will offer:
1. Our ship to shore" system
whereby passenger aboard vessel
in midoccan may get into actual
;, speaking communication with any
person on either of the two great con-
tinents, and
2. A linking of the telephone sys-
tenn and the radio, making possible
the simultaneous broadcasting to the
entire public events of national in
terest and Importance.
Exhaustive research has been con-
Quoted in these fields during the past
wear with marked success and the
practicability of both projects has
been demonstrated.
Many obstacles-principally exist
: ing rules and regulations governing
radio. coupled with certain selfish in
,rests" in the radio broadcasting field
! : sand in the way Of completion CT
| shy large scale of these projects,
| but The passage OF legislation now
pending before congress, designed 10
nevolutionize present conditions IN
radio work, would do away with such
interference, it is stated.
Development of ship to shore
telephone service has beer placed N
the hands Of 4. II. Criswold, vice
president of the American Telephone
and Telegraph Company. who as q
| colonel in the A. +. f., laid the enor-
nous communication system used by
the American forces in their major
( engagements in the late war. Last
wear Griswold demonstrated the rrac
ticability CT the ide: when he erected
/ ;, tnicphoue station at Deal Beach, =.
IT, and, with the cooperation II the
FU. S. Shipping Board Installed m
strument ard apparatus aboard the
liner America. Communication has
hoen established with the America a.
far as sixteen hundred mics out At
sea while the coastal station, com
pletely equipped as telephone c%-
change. has set up connection WIN
all parts of the country, thereby al
lowing the vessel 20 talk even 20 the
Pacific coast.
Shipping Board officials, aside from
the benefits afforded passengers de
clare such . systom would save the NJ
literally "days Of time and thousands
of dollars" in their operations. me

Negotiations are now undcr way

The communication companies OF E1N-

IT is now impossible to broadcast,
for instance, such things OF national
Importance as a presidential address
20 Congress because its delivery IS
made in the Capitol where no broad
casting equipment is set up. me
project now in process OF compile
ton would convey such . message
! from the Capitol by telephone wire to
the nearest broadcasting station.
This station, in turn, would be link
ed with others by the same type OF
| wire thus allowing Il simultaneous
broadcasting throughout the coun-
/ try.
Experiments along this line have
prcven most difficult and perplcxlne
because the ordinary telephone wire,
while fully capable OF transmitting
the sound Of the human voice over
the regular system, if tuned up 70

make audible sounds not heard IN ar
ordinary telephone conversation
which would seriously hamper, Il not
ruin, the attempted broadcasting. A,
an example is cited the fact that OF

I Telephone engineers, however, have
perfected new type of wire with a
higher frequency of oscillation, whicf
