Radio waves are the speediest
things that are, for they always
travel at the rate of $4,000 miles
second, points out Ward Seely in the
Wireless Age.
When radio operator presses
key in New York, the signal is re-
ceived in Europe about one-sixty
second Of a second afterward. Any
body who has kodak knows what
fftieth of SECOND is on the shutter
"a wink that is barely visible. If
a kodak shutter controlled radio
waves, they would reach Paris before
the shutter in New York had closed.
Have you split-second stop
watch? 1t will divide the seconds into
fftl1s. Take it out and practise start
ing and stopping the hand in a fifth
Of second. You will find that it is
quite a job to move your thumb over
a fraction of an inch in that time
but in fifth of a second radio waves
travel $4,000 miles, equal to one and
a half times around the earth.
These are not abstract scientific
facts. They are practical realities
used constantly by the Radio Cor
poraticn of America, which turns
them daily to the advantage, of bust
ness houses, private individuals, any
body and everybody who needs quick
communication across the Allan
tic.
Because radio waves are so SWIFT
is natural that the methods of con-
trolling them should be conducted at
high speed. People tend to assume
the qualities of that with which they
deal. While things do not move at
the rate of 10000 miles second in
the various RCA offices, still the few
visitors who have been privileged to
observe the methods of transmitting
and receiving have been amazed at
the speed with which messages are
handled.
1t is not at all unusual, for in
stance, radiogram to come to the
central control room at GA Broad
street, New York city, over a private
wire from any one of a number Of
bankers, brokers and others, and to
be received in Paris in less than q
minute. The telegraph operator at the
end of the private wire may tick off
the message at 1915 a. M, it is
copied on a radiogram blank by an
other telegraph operator at GA Broad
street handed to a radio operator
and he later, after having trans
mitted it to it's destination, places a
| time stamp on the blank which may
show that transmission was conn lete
at 1916. Inasmuch as the radio
waves travel practically instantan-
eously across the Atlantic, completion
of transmission means completion of
reception.

On the other side of the sea, those
who have direct wires into the Paris
radio central are able to receive their
messages with the same speed with
which they were transmitted. In the
case Of such direct-wire arrange
ments ON both sides of the Atlantic
it is a daily occurrence to get mes
sages from companies in New York
city to firms in Paris in two or three
minutes-faster than it is possible to
Telephone a message across the street
in New York city. 49, -
Of course, it is necessary for spe-
cial arrangements to be made in order
to realize speed such as this. The
most important provision is special
wire from the office of the sender
into radio central, in order. to cut to
the minimum the time consumed in
delivering the message to the radio
operator. AT the time this is written,
there are seventeen such wires, fif-
teen telegraph and two telephone, Civ
ing instant touch with banks, broker
age houses, newspapers and news as
sociatio1ls. 1nasmuch as any Of the
users Of these wires also maintain
private telegraph lines to their Of
fees in other important cities. such
/ as Philadel phia, Boston, Chicago and

St. Louis, It can be said that it IS
possible for q man in, say, Chicago.
to put message on 4 desk II Paris
in two or three minutes.
