Tns discovery OF Autobiography,
RaneraIly known as wireless telegTaphy,
Vis accomplished by the brains of the
Present age. II is without a doubt the
most important discovery Of the last
400 years. and its growth in the past
ten years has been marvellous, having
made such rapid strides that the aver
age person has not the faintest concep-
don Of the many uses to which 1t is

The wireleaS branch Of the service IN
the present war Is by far one Of Ehe
most important, and IL a very highly
specialized department OF the royal air
ferces Of Great Britain, one Of its func-
lions on land being concerned with

soecessful as partially submerged sub

Need OF Device.
Nan has always feI the need of some

VeRy recent years was dependent on
the dow work OF couriers. The school
boy knows how at the fall OF Troy, the
nSWs was communicated to Greece by
the Endling OF IRE after IRE along the
route. How different in this great age
in which we are privileged to live,
when the news Of great battles IL i'm
meeiately transmitted thousands of
miles by the modern wireless opera
tor.
This great discovery came into &C
tuAi and practical commercial use. in
1900, there being about ten years ago
only . half dozen wireless stations
in the world. while today they num-
Der IN the thousands. and were IL not
for the war, on account Of which this
Government has forbidden the erec:
ton Of private stations, there would
now be In use hundreds and hundreds
more stations throughout our broad
land In fact, many commercial
houses, railroad SYSTEMS, and steam
ship lines have commenced to adopt
this system of communication as
much cheaper and more satisfactory
than the telephone or telegraph. It
Is quite probable that all the railway
systems OF this country will shortly
equip with wireless, as among
other roads, the Delaware, Lacka-
wanna and Western railroad has
found wireless fills the bill for dis
patching trains in addition to equip
ping several OF its fast limited trains
with apparatus.
TrowbridEe ExpeF1mentn.
With all the great possibilities Of
the telegraph and telephone, they
must operate over wires, but thanks
TO Prof. John Trowbridge, of Har-
ward University, whose experiments
end discoveries on wireless messages
inspired those who followed in this
great work communication without
the aid OF connecting wires now
is possible. Trowbridge has been
called the grandfather of wireless
telegraphy. His experiments were
followed BY others, among whom
were Bell Dolbear. and Edison, but
Europe's men of science began later
to shoY great activity in their In
vestigation of wireless until an
English scientist attained consid-
cradle public notice by putting to
practical use this method OF tele-
graphing without wires But with all
the experiments and partial successes
