ratus and other devices. Practically
when it comes to the rapid vibrations
necessary to carry the human voice,
the number is very limited. There is
no way of preventing anyone within
the zone of communication from TAX
ing any message his instrument is
tuned to. And if there were many
messages at once they would interfere
with each other"
1t would appear now that these diff
fculties were being overcome for, &C
cordlng to reports from the battle
fields of France, the wireless tele-
phone is proving mighty valuable as
set in the maneuvers of modern war
fare, despite all the gunfire and the
disturbed atmospheric conditions. Co
ing over the top in trench warfare, the
old reliable telephone was a handy
asset in communicating to the rear the
results of the advance. But lately the
troops have been going forward so fast
that as soon as one telephone line
would be set up another extension
would be necessary to keep pace with
the flying Yankees.
"HeIlos" From the Clouds.
It is in the air service that the wire
less telephone now is being employed
to such remarkable advantage. Voices
out of the air, messages filtering down
through the clouds, report the Obser
vstiOns made during a reconnaissance
flight and convey to headquarters the
valued information as to the move
ments of the enemy troops.
1t is said the airplanes now in flight
uncoil long strand of wire which
acts as the antennae for transmission
of the message. An observer in a
huge plane, noting the desertion Of
village by the retreating Huns, has
but to take up the telephone and
hello his chief with the important
message. Instanter the Yankees are
| away in pursuit.
The incandescent lamp plays an i'm
p0rtant part in the great game of wire
less telephony from air fleet to land
battlements. A tiny lamp that can
generate one horsepower of energy is
used to receive the faint currents, and
larger one boosts the currents so
that the ordinary telephone apparatus
can receive them.
According to report, it is a common
occurrence for young American or
| French aviator now to be talking to
base headquarters while flying high in
the heavens so to a 100 miles away.
With the receiving apparatus on the
earth attuned to take the contact Of
wave lengths from his sending appar-
atus aloft he is able to report instant
ly on the developments below.
The wireless telephone has been lit
| tie more than ten years on the way in
the matter of actual demonstration of
theories long held tenable. 1t began
with simple experiments in the New
York laboratories Of Professor Lee De-
Forest, who succeeded in transmitting
| a distance of a few feet across ia
BILE without wires.
Message of Peace.
It was first employed at sea on ship
board in July, 1907, in reporting yacht
races from the yacht Thelma in Putin
Bay, a distance of four miles. Next
experiments were made on the battle
ship Connecticut off Cape Cod. With
out wires messages were relayed to
the battleships Kentucky and Illinois,
distance of eight miles.
From this beginning radio-telephony
was developed until trans-oceanic
communication became possible. All
that has been done in a military way
cannot be revealed until the war is
over, but it is certain then to unveil
some startling disclosures. 1t seems
certain. for one thing, that the mes
sage of peace, proclaiming the over
throw of German militarism and the
| triumph of democracy, will be relayed
| completely around the world by the
wireless telephone-a voice out of the
clear sky proclaiming the dawn Of the
great day.
