mo we're not Uncle Harry" said
Joe. But Jimmy says there is such a
hing as a wireless telephone, is
here o.
Indeed. there is" replied Uncle
Harry. And the other day when the
ship carrying President Wilson back TO
The United states. was about 500 miles
on the Atlantic Coast, Secretary OF the
Navy Daniels, picked up the telephone
In his Office at Washington and spoke
into the transmltler a message thas
was carried out over The ocean and re-
ceived aboard the Presidents ship, just
ihe same as I could send a message to
you here at the house II / called you
1n my oillce telephone tomorrow morn
lng except that my voice would be
carried over regular telephone wires,
Hhereas Secretary Daniels voice was
carried through he cir out over the
ocean on electric waves
success After Many Years Work.
Did the ship send a message back 2'
asked Joe.
10 sent back 90 Washington a mos
sage by wireless teleg-aphy saying That
Secretary Daniels telephone messag~
lad ben received but that it could not
send q wireless telephone message be
,ause lhe. ships wireless Outft was not
luipped with a powerful enough ap-
gar8tus But Secretary Daniels message
proved that a telephone message-that
S. the sound OF the voice, just as 10
s transmitted over the wires, can be
sent bv wireless, and / am sure that It
won't be many years before wireless
telephone service will be quite COM
mOn.'
"Was this method just inventedT'
sked Helen.
'N0t exactly" replied Uncle Harry.
rEyer since wireless tclegraphy was in
vented by Marconi. the great Italian,
scientists have been working on the
Idea of adapting The principle Of the
wireless GO the telephone. They have
leen making steady progress during all
'hese years and from time to time an
n0uncement has been made that the
problem was getting nearer and nearer
solution. on several occasions 10 has
been reported that wireless telephone
messages were sent over short dis
fances. But % was not until this recent
experiment was made between Wash
incton and The Presidents ship that il
was definitely proven that the wireless
telephone had been perfected and could
be used over any considerable dis
lance"
Wireless Did Great War Work.
Il think the wireless Is one OF the
most wonderful inventions that has
ever been madew exclaimed Helen.
"It is.' replied Uncle Harry. 'lt rem

that since the war started in 1911. ana
PARTICULARLY since our country entered
The conflict. The wireless experts OF the
world have made many important dis
coveries in connection with this method
0f Transmitting messages and have
made many important Improvements In
the wireless. These Improvements have.
of course. been kept secret because the
Allied Governments and our own Gov
e-nment id not want the new discov-
cries TO become known 10 Germany and
her allies. But before very long these
new inventions. which have improved
wireless telegraphy 80 much, VIII be
made public.
ayes. in this war rs in every other
phase OF modern life, electricity has
played an important part It is the
greatest and most wonderful power in
The world today, and the most surpris-
ing thing Is that electrical experts say
that the world has only made a be
sinnng-that it has merely learned the
