New Military Invention Prevents
Leaking of War Secrets.

Leaking of War Secrets.
New York: Through an ingenious
Invention of Patrick b. Delany, the
New England inventor, Uncle san
has found the means he has peel
long seeking of preventing foreign
spies from tapping government wires
and learning the secrets OF the army
navy and state departments in time
of peace or war. In the presence Oh
prominent representatives of the army
and navy and distinguished scientists
on Sunday last a demonstration OF
the invention, which possessed an
added interest because of the frequent
re-iteration of future trouble with
japan and the uncertain conditions
prevailing along the Mexican border,
was made under the joint auspices OF
the New York World and the st.
Louis Post-I dispatch.
For half an hour messages were
exchanged by the military men ana
scientists present in the two news
papers Offices 1860 miles apart. In
their Judgement, the inven tion solves
one OF the most important military
problem with which an army has had
TO contend ever since the introduction
of the telegraph as an auxiliary OF
modern warfare. The invention, Is
the latest work of Delany, who is n
Inventor of the Telepost automatic
telegraph system, and multiplex, the
antipage relay and other improve
ments to the telegraph and cable. 1t
breaks up the dots and dashes form
ing the letters Of the telegraph code
and required the use of W circuits,
~traversing widely separated territory.
One went to ST. Louis by way OF
Philadelphia, Pittsburg. Columbus,
indianapolis and Terre Haute and
the other by way of Albany, Buffalo,
Cleveland, Toledo. and Chicago.
The two wires were controlled and
operated from an ordinary single
Morse key and the message was re-
ceived over a single receiver at the
end of It's journey In the same way as
a regular communication. Each alter
nate dote or dash travelled over one
wire and the other dots and dashes
over the other. Though the distance
by way of one route was hundreds OF
miles longer than that of the other;
each impulse reached the receiving
instrument In its proper sequence. BY
tapping either wire all that the secret
agent OF an enemy would
have gotten from it would have been
a series of meaningless cabalistics OF
no value to him. Parting company at
the sending key the " parts OF the
message, separated by many miles
throughout their flight across country
we're only reunited at the receiver
the tapping of either wire
the transit of the message of
no use whatsoever.
The mechanical device that &C
complishes this is very simple, requir-
es no special skill to operate, and can
be used in any combination of two
circuits OF which the telegraph is
susceptible. 1t makes the coding of
government messages un-
necessary, thus saving hours Of valu-
able time In periods OF urgency when
minutes are vital to the success OF a
and will defy the ingenuity
Of a foe to extract from the wires any
thing that can be made of service or
profit to it. Delany presided at the
demonstration in the World office on
this end, where 1t was witnessed by
Hudson Maxim, General A. r. Buff
U. S. A. former Chief of
Commander J. w. Oman,
u. S. N. representing Admiral Leutzs,
commandment of the Brooklyn Navy
Yard; Midshipman w. A. Richardson,
U. S. N. representing Admiral Seton
Schroeder, Of the Atlantic fleet now
In port and other officers of the army
and navy.
In the Post Dispatch office were
Colonel W. A. Mann, q. S. A. and
Captain H. S. H. Ford, U. S. A. Of
Jefferson Barracks, st. Louis.
We've got the enemy bottled up
this time said General Burlington,
when the demonstration was over
''The day of stealing our dispatches is
now over, thank Cod
