maze some very lmpOltdll CpIlI lDu-
tions 10 the development Of wireless
telephony. Among these is the pres
ent system he is working on, IN con
junction with c. s. Franklin OF his
English company.
Reflected Waves for Telephony
These experiments involve the use of
reflected waves of very small length.
When finally successful the system will
be one Of the most revolutionary in me
history Of radio development
In order 20 understand this expert
mentation. it IS well to 70 back 10 tho
early days OF wireless telegraphy. when
Marconi succeeded in communi eating
over a distance Of mile. Al that time
he was using refec.ors IN order "a
shoot a beam Of electro magnetic
waves straight toward the place he
wished 10 Communicate with. Later
when wireless was applied 20 ships
this system was utterly impracticablC
because Of the fact that ships were
constantly moving and thereby chang
ING their relative position 40 regards
other ships and the land.
II is not generally known that We
can do with electromagnetic waves
just the same things We can with ligh;
waves. and among these things is our
ability 20 reflect them. IN exactly the
same manner as we reflect light waves
with a mirror OF course. in wireless
entirely different apparatus is neces.
ssry TO reflect the waves
System Gives Great Secrecy
With this system working with wave
lengths Of two meters. Franklin and
Marconi have been successful in tele.
phoning over a distance Of 100 miles
with a degree Of secrecy never before
dreamed Of. As matter Of fact, no
one but those In a direct line with the
beam Of waves can receive the conyer.
sation. Tho remarkable thing abou,
these experiments IS that they involve
electric currents alternating at the
stupondous rate OF 15O.OOOO00 cycles
a second
These are some Of the things that
are being undertaken aboard the re-
msrkable yacht There is no doubt
however. that the public will always
associate ahe yacht with attempts %
communicate with the planet Mars
This IS due 20 the remark which Mar
conf iokingly made while discussing
the subject with a newspaper man in
Europe who was not acquainted with
radio
II arose ~ tho time when Marconi
announced that he had succeeded in
recording electromagnetic waves i50,
600 meters in length while his
yacht was in Mediterranean waters
Waves OF this length have never be-
fore been recorded, and special ap-
paratus was necessary 70 get them.
Talk With Mars a Joke
In discussing them with me during
his stay in New York this time. Mr.
Marconi said: Il was only joking when
said that they were signals from
Mars. Ny little joke was taken seri-
ously. What 7 said IN amplifca.ion
Of this was: These very long waves
are entirely different in their charac-
tcristics TO sny that are produced on
the earth. was quite convinced that
they came from outside the world. Just
what they were ! had no idea. They
might be the result Of some vast cleo
trical disturbance in the planets or
from the sun"
Although he has listened az different
times since then. Marconi has never
again heard the mysterious waves
