MARVELLOUS
Invention
Will Be Used As Lookout
For Submarines.
Finder Was Devised By Marconi
Italian Patriot And Inven-
tive Wizard.

Marconi's wireless "eye," by which
war ships may locate their prey or
startled merchant vessels may be
apprised of danger. gives new sig
nificance to Italy's attitude during
the war.
Marconi is an Italian patriot as
we'll as a wizard inventor.
Since the tryout of the wireless
Mariners" on the Royal Line steam
ship Royal George during June, the
full significance of the invention has
been revealed by the sudden Euro
pean war.
Should the device be available to
all warning nations on equal terms
it may hasten the end of the con-
flict. But should Italy's attitude to-
titude toward the nations at war
give one side the benefit, this wire
less marvel may decide the fate of
nations.
Already the control of Marconi's
wireless tongue" the telegraph is
matter of grave international mo-
ment The means to "see" wirelessly
fifty miles over the ocean, war
cruisers or other craft. has in it a
potential power for the rival navies
which can not be foreseen.
1t was in June that David Sarn-
hoff. contract manager of the Mar
conf Wireless Telegraph Company,
of America. explained in his offices
in New York the possibilities of the
wireless direction finder with which
the Canadian Northern's liner Roy
al George has been euipped. This
apparatus, he said, will enable the
ships navigating officers to find the
position of the ship in relation to
any fixed or moving wireless tele-
graph station within a radius of
fifty miles, regardless of weather
conditions. ...'
The new device is classified as a
direction finder" Its duty is to seek
out all wireless stations, whether
stationary or in motion-or in other
words, on coast line or high seas.
within a radius Of fifty miles and
to indicate for the guidance of the
navigating officers the exact rela-
ton Of the ship to these in terms
latitude and longitude. It's sphere
of usefulness. even in the present
experimental stage. is to assist the
captain during thick weather. in
maintaining a clear course in the
travelled ocean Flames" in passing
points and making ports.
What such device can do in
warning ships officers of approach
ing enemies or fleeing prizes is evil
dent.
Like many inventions useful to
mankind this wireless finder is re-
markable for it's simplicity. Altho
one of Marconi's engineers, Signor
Emilio Ichino. was on the Royal
George to make the tests, it's opera
tion does not require an expert and
any of the bridge officers can obtain
bearing as easily as with a COM
pass and ust as conveniently, the
instrument being set up in the chart
room.
The device is not bulky. The "di-
rector" box. which is the medium for
locating the wireless stations, is but
large enough to hold two small
switches and a graduated dial fitted
with a movable indicator. Connected
with this cabinet is the telephone
box differing from others in that it
is equipped with a crystal of car
borundum which translates the wire
less into a signal Ineligible to the
ear of the operator. There are two
receivers fastened to the ears Of the
operator by metal straps going over
the head. Then. too, the device diff
fers from the ordinary wireless APP
apparatus in the serials, according to
Sarnhoff.
By the finder a wireless operator
on shipboard determines the direc-
tion of message to him. This d.
rection is found in relation to the
course OF the ship; or. In other
words. the finder indicates the angle
which Q strsight line between the
station on the ship and the station
