respect very well with the results obtained by
Mahajan, and by him described with illustra-
tions in a most interesting paper on the vibra-
tions of the pianoforte soundboard, published
in the Indian Journal of Physics, volume 4, part
6, published at Calcutta by the Indian Associa-
tion for the Cultivation of Science. Mahajan's
results, were obtained mechanically, by photo-
graphing the movements of an illuminated mir-
ror attached to a light steel pin, which was
caused to move by the vibratory motion of the
rib of a pianoforte soundboard, against which
the pin was arranged to roll. This mechanism
might have been expected to display the effects
of mechanical friction to a greater extent than
ours, but the agreement, so far as our work has
gone, is quite remarkable. On the other hand,
improved pick-up on our part may give us
more complex wave-forms from the sound-
board, more closely corresponding with the
wave forms given out from the complete sound
as microphonically received. The question
meanwhile arises: if our pick-up is doing its
duty effectively, how is it that the sounds of
the piano as heard are so much more complex
than the motions of the soundboard?
2. There is a remarkable falling off in reso-
nating power from the central region of the
board toward the rim, in all directions. The
region of effective resonance for the whole
3. The maximum resonance point for each
note is individually and separately placed,
although most of them are grouped together
within the small space mentioned above.
4. The effectiveness of the board as resona-
tor appears to be nearly proportionate inversely
to the stiffness. The small area of maximum
resonance is very close to the physical center
of the board, where the stiffness is smallest.
These are all the statements which I feel
justified at the moment in making but I will
have more positive data within a month or two.

scale appears to lie diagonally and roughly in
the shape of a very flat ellipse starting some-
where in the region of the C 52 strings and fol-
lowing roughly the direction of the treble bridge,
towards the bass bridge. The region is from
15 to 20 inches wide, and occupies a large part
of the space between the front or head-block
edge of the board and the treble bridge. Out-
side of this region towards the rim, the drop
in resonating power is sudden and precipitous.
Inside the region, the area of maximum reso-
nance for all notes is very small, being only a
few inches square, and from it towards the
boundaries there is an abrupt descent in effec-
tiveness beginning within six inches of the cen-
tral point as determined for each note.

Waters & Ross Open New "Uncle Jack" Plays the
Sheet Music Department
Rolmonica Over Radio
SAN
FRANCISCO, CAL.—Waters & Ross, of San
Francisco, have recently made a number of
changes in their store, in order to install a
large department for sheet music.
All the
phonograph booths have been removed and the
space devoted to the firm's latest activity,
which is in charge of K. Fuhrman, one of the
best-known merchants of printed music in San
Francisco. Speaking for The Music Trade Re-
view, Mr. Fuhrman said that they will carry
a little popular music, a wide selection of band
and orchestra music, and will also specialize on
educational music and music for school bands
and orchestras, in addition to educational music
for piano and vocal students.
"Uncle Jack," of WCAO Safety Club, Balti-
more, Md., has endeared himself to the chil-
dren of Baltimore by the program which he
puts on daily and in which he has made the
Rolmonica an important feature. "Uncle Jack"
gives complete and readily understood instruc-
tion for the proper playing of the harmonica.
Illustrations help to make the text more com-
prehensive. The other publication is a har-
monica transposing chart, which makes possi-
ble harmonica arrangements for musical se-
lections written in eleven different keys. Both
publications are modestly priced, and are al-
ready available for distribution to jobbers and
dealers.

The Robbins Music Corp. recently held the
formal opening of an elaborate new professional

the modern manner representing a particularly
interesting example of what can be done in the
modernistic art.

is none other than Don Hicks, who was born in
a small town near Columbus, O., and showed
a marked liking for the stage at an early age,
at that time joining a vaudeville troupe playing
in Chicago. He has been a newspaper car-
toonist, in motion pictures, a publicity manager,
and played one year in stock with Charlie
Chaplin. After serving with the California
Coast Artillery throughout the war, he became
interested in radio announcing, and one of his
first programs from WCAO was the "Movie
Answer Man."
His creation of the Safety Club in Baltimore
won a quick response from the children in that
city, to whom he is known as "Uncle Jack."
The accompanying illustration shows him play-
ing the Rolmonica during one of his programs.
New Ensemble for Radio
A new name entrant in the radio field
shortly will be the Grofe-Wiedoeft Ensemble,
consisting of Ferde Grofe, musical arranger and
composer; Rudy Wiedoeft, saxophone virtuoso,
and H. Emerson Yorke, former Eastern casting
director for Paramount pictures.
With an orchestra of thirty-one picked mu-
sicians under the Grofe baton, this ensemble
gave an impressive radio audition recently, both
in New York City and Chicago, for a repre-
sentative group of national advertisers.
Ashley Music Supply Co.
Organized in New York
Abe Schlager, for the past fifteen years ac-
tively identified with the wholesale sheet music
industry, the last eight years of which were
spent with the Richmond-Mayer Music Corp.,
as service manager, has formed the Ashley
Music Supply Co., with headquarters in the
Gaiety Theatre Building, 1547 Broadway, New
York. The Ashley company will distribute
everything in music. Associated with Mr.
Schlager, as sales manager, is Phil Moore, who
also has had long experience in the trade.
Two Valuable Books for
. Harmonica Students
There has recently been published by Irving
& Davis, Philadelphia, two valuable helps for
the harmonica player, prepared by Fred Son-
nen, widely recognized as a harmonica teacher
and soloist. The first is a booklet entitled "The
Harmonica Student," in which Mr. Sonnen
