Francis Scott Key Memorial at Fort
McHenry on June Ii than ever before

State.
President Harding's words and
those of the other speakers will be
carried to thousands. attending the
exercises through the BELL Loud
Speaker" or telephone amplifier. The
intricate machinery which will make
IL possible for all within an extensive
area to hear as distinctly as if they

by the Chesapeake and Potomac Tele-
phone Company at the personal re-
quest of Mayor Broening, of Balti-

First Time In State
II will be the first time that this
complete amplifying apparatus has
been used in MARYLAND at a big out
door gathering. II was last used in
washington at the dedication of the
Lincoln Memorial on May 80, when
about 10000 people heard President
Harding, Chief Justice Taft and other
distinguished men speak through the
medium of the amplfier. The ampli-
iler performed perfectly on that oc-
casion and called forth the praise of
thousands.
The huge figure representing the
spirit of song in memory of Key the
poet, has been placed on its pedestal
OF fawless Tennessee marble. The
total height OF the monument is forty
feet. Skilled workers in stone are
now putting the finishing touches on
the figures on the base. One of these
Is bas relief of Key. Every minute
of the day this work is under the
watchful eve of Charles III. Niehaus
the sculptor.
Placing speaker" In Position
Telephone engineers are now busily
engaged setting up the machinery of
the Loud Speaker" This will be
completed in several days. The three
or four days Immediately preceding
the unveiling are to be devoted to
testing the mechanism and adjusting
1t minutely so it will carry the
speakers words, music of the band,
and singing of the children's chorus.
to all who attend the exercises. The
amplifier was developed in the labora-
tories of the Bell System and is only
used on notable occasions when large
crowds gather, since it is not a COM
mercial device.
Those attending the unveiling who
are beyond the range of the natural
voice of the speakers will be unable
to detect any unnatural sound as it
comes to them through the Loud
Speaker" There will be no shouting
tones such as issue from a mega
phone. Every infection in the speak
er's voice and pause and emphasis of
his address will be faithfully pre-
served by the apparatus.
To Carry Voice Broadcast
The loud speaking projectors
through which the addresses and
music will be conveyed will be erect
ed on a tower and will send forth the
sounds in all directions. Before the
speakers will be a small box covered
with white cloth and this device will
catch the sounds like telephone re-
ceiver. Over wires leading from this
receiver. the sound waves will be car
ried to the amplifying apparatus in
side one of the buildings of the Fort
and there increased in volume many
millions of times. They reach the
audience greatly strengthened but
with the original tones preserved.
Memorial Tribute OF L. s.
The Key Memorial is the tribute of
the United States Government to the
man who wrote THE Star-Spangled
Banner" and it is erected near the
spot where Key stood when he wrote
the words of what is now the national
anthem. City officials, headed by
Mayor Broening. are cooperating
with government officials to make the
unveiling complete success and an
event long to be remembered in Mary
land.
