Wireless Telegraphy.
w. B. Hinkle Of this city who
has been studying scientific sub
jects at ST. Mary's college in Oak
land, California, has written a num-
Der OF articles that r being
widely published and ~favorably
received. In a recent issue of
. San Francisco paper the follow
ing article on wireless telegraphy
appeared:
The present age is probably the
greatest in the history Of science
and invention. In fact, science
is advancing with such marvellous
strides that the ordinary reader
and student can only grasp the
more important discoveries and
wonder what will follow. Ever
since Benjamin Franklin discov-
cred that electricity and lightning
are identical, developments in
electricity have rapidly succeeded
n another until to-day the world
is almost run by the invisible, phe-
nomenal power.
The history OF the world is d.
vided into ages, according as the
advancement of some particular
branch of learning arose above the
others. Thus we have the age OF
art, when the wielder of the brush
worked marvels on canvas; the age
of literature, when writers rose to
great prominence, perhaps never
to be eQualled; when orators, such
as Demosthenes, thrilled the world
with their %eloquence and convinced
nations by their mastery reason
ing. So, now, we have reached an
age of science. The student of to-
day must know something of the
sciences if he expects to achieve
success when he enters the worlds
mad struggle for position ane
power. Such discoveries and in
ventions as radium, the X-rays
wireless telegraphy, ETC., are, II
all likelihood, but forerunners o
greater things.
Although scientists have beef
working on the subject for man.
years, wireless tefegraphy has onl.
in recent years been brough
to a state of efficiency.
In 1852, Calico wrote a dialOgu'
in which a character is made t.
saw: "You remind me Of one VIII
offered to sell me 9 secret art, b,
which through the attractions Of
certain magnet needle it would b
possible to converse across a spac
of two or three thousand miles.
In the bible we find this strikin
sentence: "Canst thou send light
nings, that may 60 and say unit
thee, Here we are ~
These things come to US to-da
as if they were prophecies, for "

We send them not only q lit
distance, but also across the gre'
Atlantic, and it is even possib
that hereafter they may be SCI
around the world.
In late years many renowne
scientists have been working {
wireless telegraphy. Among thes
Steinheil, Davy, Hertz, Mors
Edison and MarcoDi hold the fir
/. rank. 1t was the GROWING wol
OF Marconi, however, that broug
wireless telegraphy into practic
application.
Marconi was born at Bologn
Italy, on April %, 1874. d
father was an italian noblema
and his mother OF Irish rationale
He lie a graduate Of the Universe
of Bologna, and has been interest
in wireless telegraphy since he "
about 16 years OF age.
The principle Of wireless tele
raphy is the propagation of eli
trio waves through the air. II
theory was first advocated
Hertz, who experimental consid'
ably along this line, but failed
far as ~telegraphy was concerne
Marconi continued the work
Hertz, and after many experiment
concluded that a sharply defin

through a spark-gap OF suita'

vibrations. Such vibrations
