By System Of Wireless TsIsgra-
ply Just Put In Operation.
APPARATUS SMALL AND CHEAP
Ground Is Used for Transmission Tones
Divided Into 4],000 Pitches Pass Each
Other without Interference

London. Oct 2i.-Scientihe London
stands astognded but deeply gratined at
the results of experiments with the new
system of wireless telegraphy. as II may
be called, although IL Is really much more
than a mere transmission OF telegraphic
signals
Sounds, as they are conveyed over the
telephone circuits. are sent by this won
derful system and, Of great further i'm
portance,eleciricsl power OF high strength
speeds to distant points aud does It's work
Just as well as II n were carried by tho
ordinary metallic circuits
Indeed, the new system known az the
ArmoHi system. bears many points Of SUI
periority over that Of Marconi. whom all
honor as the pioneer. the Columbus of
wireless communication
The invention Is the Joint work of Ariel
orling. swede, and J. r. Armstrong. an
Engiishman. who have been working With

markshle ideas, making actual facts OF

GROUND FOR TRANSMISSION.
The new invention docs not use the air
for transmission as does that OF Marconi
The electric waves are sent through the
ground. and one charm IS tho simplicity
and cheapness of the electrical installa-
alton.
al present. 10 hoist the sending and re-
oeiving points far into the air, out OF the
reach OF interference
There can be no interference by the
Armorii system. Mr. Armstrong has dis
covered that he can vary the pitch or
tone in which the radiations arc sent
much after the fashion OF the auadru-
pick and duplex systems In telcgraphy,
hy which the electric currents arc divid-
ed and pass each other on one wire with
out interference
There are i0,o00 different tones. no one
or which win conflict with another. so
the chance of two tones of the same na-
ture meeting and destroying one or both
Is reduced TO one I'm 10000
Yesterdays experiments were made AT
the home OF Mr. Armstrong In Bucking-
hamshire. The conditions were OF the
worst, since q heavy rain had fallen for
% hours and there was a thick fog en-
veloping everything. Nevertheless the ex-
periments were absolutely satisfactory TO
the experts invited to witness them.
