FROM THE BIGGEST
ORCHESTRION
MAY PHOTOGRAPH TALKS
AT NEXT CONVENTION
Instead of Pounding a Typewriter, Secretary
Kennedy May Turn a Crank—Other
Possibilities of Newest Invention.
Photographing the human voice and the production
of a negative which can be projected by radio at any
time and preserved indefinitely are facts proved last
week "by Charles A. Hoxie of the General Electric
Company at a meeting of the American Institute of
Electrical Engineers in New York. The Pallophoto-
phone, a device which photographs sound on motion
picture films will revolutionize commercial methods
to a considerable extent.
Perhaps at the Drake Hotel next June Secretary
Matt Kennedy may forgo the ancient method of fil-
ing the minutes of the meetings of the National As-
sociation of Music Merchants, and instead procure* a
photograph record of all the sights and sounds occur-
ring at the various sessions. The Pallophotophone
used in conjunction with a moving picture camera
gets the indisputable record of the attendance and
what everybody says. By this method the minutes
arc given rare historic value.
When the manager of active sales department in
the New York or Chicago piano factory, for instance,
has an important new feature in one of the instru-
ments to point out to the road force it may not be
necessary in future to summon the travelers to come
long distances to see and hear it. The Pallophoto-
phone and photograph combination record could tell
the facts and show the operations of the new part if
such were necessary to convey the increased ad-
vantages to the salesmen gathered by appointment at
some central sectional point. What is said and seen
at a gathering of Baldwin travelers in Cincinnati or
of Packard road hustlers in Fort Wayne, Ind., could
be and possibly will be provided for assemblages of
the sales force in distant sections.
The test of the Pallophotophone given by Mr.
Hoxie to the engineers in New York was conclusive.
The Pallophotophone was first used in December,
he explained, to photograph the voice of Vice-Presi-
dent Coolidge and other national figures. These rec-
ords were broadcast later by radio from Schenectady.
When the Pallophotophone is used to photograph
speech on a sensitized film, the voice or sound actu-
ates a diaphragm, Mr. Hoxie explained. This in turn
causes a corresponding vibration of a tiny mirror
fastened firmly on a steel shaft between two sets of
jewels.
A beam of light from a special incandescent lamp
is focused on the mirror by means of a spherical lens
and the vibrating mirror reflects the light through an
aperture past which the sensitized film is moving at
the rate of a foot per second.
The voice vibrations are thus recorded in a series
of up and down markings of varying frequency and
amplified. After the film has been developed and
dried it can be made to reproduce the speech which
was used in making it.

MANUFACTURERS BEFORE SENATE.
Fourteen representatives of as many industries ap-
peared before the senate immigration committee this
week and demonstrated specifically a shortage of la-.
bor in many of the great producing states. This
action was in support of the Colt immigration bill,
which provides mainly that the immigration quota
be figured on the net instead of on the inflexible 3
per cent, and also that the Secretary of Labor be
given power to permit the admission of immigrants
in excess of the quota when such necessity is made
clear to him, to meet certain industrial requirements.
FRENCH RADIO SERVICE. •
Installation of radio sets is made by French manu-
facturers under contracts which provide for rental of
375 francs a month, plus installation costs. In case
vessels which become idle for any reason, after hav-
ing used the service two months, the rate is reduced
to 300 francs a month. If the shipowner decides to
lay up the vessel or to discontinue permanently the
use of the radio apparatus, he makes a lump sum pay-
ment of 4,000 francs to the manufacturers and returns
the apparatus.
ACTIVE CALIFORNIA FIRM.
The Shuck Music Co., Glendale, Calif., in addition.
to a fine piano and playerpiano line, also carries two
makes of talking machines, a full line of records, and
a well-assorted stock of musical merchandise, includ-'
ing baud instruments.
CHICAGO'S SILENT NIGHT.
Monday has been designated as "silent night" for
Chicago radio fans. At 7 o'clock every Monday
night the broadcasting stations of the city will close,'
and for five hours the fans of the-city will have an
opportunity to "fish" for out of town stations with-
out being interrupted.
Talking machines have been added by Lansburgh
& Bro., a Washington, D. C, department store.

Knowing the Relation of Portraits on Bills to
Denomination Is Safeguard.
The raising of bills has superseded counterfeiting,
especially with Federal Reserve bank notes, accord-
ing to officials of the bank. Although there are
only about two dozen different notes ni common use,
HI denominations of $100 or less, only experienced
bank tellers can name the pictures on them.
If you know the picture that should be on a bill
of certain denomination you can readily tell if it has
been "raised." There are five kinds of paper money
now in ordinary circulation, of which Federal Re-
serve notes and bank notes are the most common.
Here they are, with the portrait on each bill:
