method is by the direct focusing Of
the actual scenery. Illuminated by sun
light or artificial means, ont" the cell.
+ Possibilities of this latter phase
appear to be numberless. For eX-
ample, a person may stand with his
face in = strong light. much as he
would do to be photographed. and
have his portrait Immediately broad
cast to a friend hundreds of miles
away. Instant identification of cap
tured criminal suspects in distant
cities could be accomplished by fore
ing them thus to have their facial
features and other distinguishing
characteristics sent by radio to de-
tectives engaged in 4 man-hunt. Artf-
clss which have been stolen and car
ried away to out-of-town points also
could be identified quickly. Thumb
prints of escaped criminals, spies. etc.
could be easily broadcast throughout
the country before the fleeing men
had had time to get many miles away
from places of captivity. Reward
notices, police "lookouts' and sim
liar information placards may thus be
distributed over a wide territory in
the course Of few minutes.
In connection with the phase just
mentioned. il is predicted by those
who have seen Mr.. Jenkins invention
that complete typewriter or printed
pages. illustrated with pictures. cor
tanning bulletin news of national I'M
portance, before long will be broad
cast to publica ations scattered in va
r;ous sections Of the country, which.
in turn. could make etchings direct
from the developed print Of a bulletin
and run Off copies of it without the
necessity of setting UP type or MAX
ing several engravinss.
Banks and financial institutions
should find the process invaluable for
sending signatures to other cities to
compare with original handwriting
and thus verify the worth or worth
lessness Of a suspected check. In de-
tective work. this method of identify
ing handwriting should also find a
wide field.
In the world of motion pictures the
device may be used to project through
the ether news pictures to the large
theaters and thus put news events
before the public almost before the
newspapers can print telegraphic
news. Nj. jenkins asserts that no
newspaper can possibly put a distant
news event into print as quickly as
the theater could with radio pictures.

AIOTION pictures by radio, Mr.. Jen-
lNl, kins told The Star representa-
tive, differ from still pictures only in
speed" 1t is a matter of few
months when apparatus capable of
producing this speed Of projection
can be built. Development of radio
motion pictures, he added, will not
be actively pushed until news pictures
by radio have been permanently es-
tablished in useful service.
AS lights which make up radio pic
lures and the radio which carries
them are both practically limitless.
the solution of the only remaining
problem seems we'll within reasonable
expectation of early accomplishment.
From the very nature Of the inven-
tion 1t would seem that in the home
motion pictures by radio would ultf-
mately find greatest usefulness, ac-
cording to Mr.. jenkins.
Radio movies might also be found
useful in schools, churches. oranges
and clubs Perhaps even the theater
may ultimately be changed from cell
luloid to radio.
To transmit a still" picture by
radio in Mr.. Jenkins laboratory re-
ouires from three to six minutes at
the present time. that period being
required for the whole image to travel
across the cell of the sending outfit.
A specially designed prismatic ring
which the inventor has devised will
enable each picture to be projected
almost instantly. SO that a rapid sue
cession Of pictures, such as the ex-
posures on a motion picture film. can
be sent out and received on screen
again from the air In the form Of
movies. In the course Of the next year
