IMPORTANCE OF WIRELESS
TELEGRAPHY IN WAR TIMES
WRITTEN FOR THE SUNDAY REPUBLIC.

WRITTEN FOR THE SUNDAY REPUBLIC
In the next war wireless telegraphy will
| prove an important factor!
+, Whether the battle be waged on land or
| sea. between armies or navies, the wire
less Transmission Of intelligence will loom
| up. a gigantic specter. dreaded by the
enemy like a mirage in the desert By the
| traveller
Ever ance the advent Of this seeming
miracle. eoualing in every respect the teIe-
PATTY OF which We have SO long dreamed
| the Powers Of the world have been testing
| It's merits 50 that when the next war In on
and the crucial moment arrives, troops or
vessels may communicate with each other
even though distance OF fifty miles sepa-
rates them.
The military wireless telegraph hero H.
lustrated Is known as the Braun-Siemsns
q Holske system and Is the invention Of
Professor Ferdinand Braun, instructor IN
electrical engineering in the Physical IN
stitute. Strassburg, Germany, and the an
paratus is manufactured by the s!enens
& Holske Electric Company of Berlin.
Inc equipments were specially designed
Tor the recent German army maneuvers ana
We're placed In charge Of the Royal Military
Airship Battalion. During the trials OF
transmitting and receiving wireless mos
sages after hard runs and forced marches
the results were witnessed by tho Kaiser,
who evinced his approval Of the operations
CONDITIONS WEIRD SEVERE
The conditions under which tho battaliou
rendered its telegraphic service were sever,
In the extreme. as. for instance, in the
cross country runs. when the carriasss
were carried overland at terrific Fpeed.
limited only by the endurance and ability
of the horses.
When the command would Be suddenly
shouted to make ready the horses would
be drawn up. the engineers Of the battalion
would start the gasoline engine and dy.
namo. supplying electricity to the sending
instrument. while others of tho battalion
would send kite soaring through the air
heavenward several hundred feet and carry
Ing the aerial wire which Is ordinarily sus-
pended from n mast
simultaneously the receiving Aquarium
would be adjusted and II was found that IL
required just five minutes to get everythine
into working order to send and receive mos
sages.
hTe object of these manoeuvres was 70 d.
ternine whether or not tho delicate and
sensitive instruments employed in wireless
telegraphy would be able to Withstand the
hard usage. as well as the value from q
strategic point of view.
With these thoughts as the dominating
factors two experimental stations were
set up. one Of them being located on the
Rusen at Laprfntz. and the other on the
Pnmeranan Coast. at Gross Molten.
These stations were of the regulation
type. having masts seventy-fve feet in
height. from which the sending and re-
ceiving wires were suspended. These two
permanent stations constituted the base
from which the orders were issued
WIRELESS INSTRUMENTS
Three OF the portable wireless telegraph
systems for the field completed the military
Announcements for wireless signalling. which
was TO take place in a zone approximatins
thirty-fve miles. radius sufficiently great
to insure its usefulness in actual warfare.
The instruments of the portable military
outfits are similar to those of the permanent
station sets. and the general principles
the construction of the ap-
paratus are the same as those of the Mar
,oni system-that is to say. the transmitter,
carried on enc of the carriages consists of
a generator for sending out the invisible
electric waves by means of the aerial wire.
The generator is al induction coil. having
/ spark-gap connected to a copper cylinder,
'r artificial earth. as 1t Is termed, and the
Isrtal wire
