OVER TEN FOLD
New Method Now Being
Perfected, Says Gen
eral Saltzman

WASHINGTON, Nov. 22.-The asso-
citation of photography with RADIO
points to a revolutionary change in the
fundamental methods of communication
transmission.
Military experts are watching the ad-
vance of communication sciences and
authorize the statement, made public
today in the annual report of Major
General c. Mex. Saltzman, chief of
the Army Signal Corps, that messages
of the future, whether written, printed
or mixed with diagrams and photo
graphs will, ut seems certain, soon be
transmitted photographically by radio
frequency at rate tens of times faster
than was ever possible by the dot and
dash methods of hand transmission"
Old Method Doomed
Looking into the future of signal
communication for a moment" General
Saltzman says, lit appears that the
basic method Of breaking messages in
to words, into letters, letters into dots
and dashes, and then passing these
through the wrist of an operator, as has
been the practice since fMorse's funda-
mental invention of the electric tele-
graph, seems to be nearing the end
of a cycle. Mechanical transmitters,
with higher speed qualities, are becom-
ing stabilized and American invention
seems to be making further and rapid
progress in associating photography
with RADIO, which bids fair to revolu-
tionize fundamental methods of trans
mission.
The message Of the future, whether
it be written, printed or mixed with
diagrams and photographs, including
the signature of the sender, will, it
seems certain, soon be transmitted photo
graphically by radio frequency at a rate
tens of times faster than5was ever pos
sible by the dot and dash methods of
hand transmission.
Contain Sketches
Military messages of the future,
particularly in active operations, may
contain diagrams and sketches or even
entire sheets of maps, all transmitted
as part of the same message and by
means Of which detection or listening
in will be reduced to very low
minimum.
The signal corps is keeping abreast
of this progress and will undertake ex-
perimtnts to establish tie military
value of this invention"
General Saltzman points out that the
army deserves considerable credit for
the work of procuring and laying down
cable requirements on the Washington
Alaska; cable and Telegraph system.
During the year ended June 80, the re-
port shows, the cable ship Dellwood
laid 955 miles of submarine cable from
Seattle to Ketchikan, Alaska, and soon
would complete the project at a figure
far less than would have cost the gov
eminent had the job been given to com
mercial enterprise.
First Cableship
The Dellwood was obtained from the
United States Shipping Board and
equipped for its task in Alaska waters.
The main point in the acquisition of
the vessel and the laying of the cable
replacement, the report adds: sis that
the Dellwood ushers in for the first
time cableship under the American
flag, capable of carrying on deep sea
submarine cable operations in any
ocean, and capable also of CARRYING in
her tanks thounsand miles or more
of cable, fact which may prove of
lnestlmable value to the country"
