New York.-President Harding,
who set record for long-distance or
atory on Armistice day by addressing
simultaneously three great throngs of
more than 100000 persons, gathered at
Arlington National cemetery, San
Francisco and New York, may easily
find himself talking to an audience
running high into the millions and
scattered through every state in the
Union, before he leaves the White
House.
Indeed, says r. w. King, one of the
American Telephone and Telegraph
company engineers, whose work on
the loud-speaking device made posi-
BILE the ushering In of a new epoch in
space humiliation at the ceremonies
over the bier of Americas unknown
soldier, 1t Is well within the range of
possibility that President Harding may
see the day when President can sit
ut ease In the White House and talk
at once to every city, town and ham,
let In the United States that is tapped
by telephone wires. An audience of
tO,0O0.OO0 perhaps! Or 1OO,OOO,OO0!

into the faces Of column Of ciphers.
marching In threes across great open
white spaces, is one of the prerequi-
sites even to thinking about that mar

plifier, of which the loud-speaking de-
vice is only one In long list of prac-
teal applications.

1t took 100000 600, 900, 900 amplih.
cations to convey the grafton and the
other ceremonies to San Francisco sc
that they could have been heard
through an ordinary telephone receiv'
err. Then they had to be amplified a
million million times by the loud
speaking device.
A mere ten-million billions-10, OOO,'
O00, OO0, 600, 000-of amplifications were
necessary to bring the ceremonies out
clear and strong in New York. Ter
thousand were used to bring the cere
MONIES here, and million million to
raise them to audibility for the New
York audience. The other million mil
lion amplifications were used to carry
the Presidents voice to the Arlington
crowd.
BY providing few more scores o,
thousands of miles of wire, some thou
sands Of loud-speaking devices and
few foolscap sheets filled with tiny
ciphers indicating more amplifications
the entire country might hear future
public ceremonies. Mr.. King said.
It would be relatively simple, he de
rclared, to set up equipment In the CAPT
tails Of the 4S states through which
10000 persons in each city-a total Of
1900 O0-could hear ceremony ir
Washington or elsewhere as distinctly
as IL they were seated within a few
yards Of the speaker.
A Rival Of "Canned" Music.
Scanned" music, too, faces poten
tial rival In the loud speaker. Tele
phone engineers say the Armistice day
experiment proved that music coult

on the best photograph records ant
that II will be a matter Of but a few
years when the last vestige OF metallic
ring will be eliminated.
Mr.. King believes 1t will be but
short time, too, until all the principa
public halls and large university audi
toriums are equipped at least with 10
cal loud speakers. These, he pointed
nut, could easily be switched on long
distance circuits carrying public ad
dresses and similar events from othel
gities.
