TElEGRAPHY BY INDUCTION
SUCCESS IN SENDING MESSAGES
THROUGH SPACE.

The continued success which has at
tended experiments in sending tele-
graphic messages through space prom
ises TO lead to remarkable Developments.
An English electrician says II is difficult
TO forecast the future of this new teleg-
raphy. So far. signaling has been
carried on by this means In one direc-
ton only. but there is no reason why
messages should not be duplicated.
and even quadruplicated. Further
details are now AT hand OF the
establishment Of communication between
the Island Of Null and the mainland,
near Obau, few weeks ago, when the
connecting cable broke down. IL viii
be remembered that an insulated wire
was laid along the shore OF the island
and messages through Il were sent
to the mainland across two miles OF
intervening space. The Official report
states, "An ordinary Morse circuit could
not have given better results. The chiei
difficulty wa. the incessant screaming OF
the wild fowl" W. III. Prcece, In COM
menting on the achievement, finds u
very different explanation OF this sup

sounds are frequently heard on long
lines of telegraph In the calm stiffness

An electrician has expressed his belief
that telcphoning 70 the moon is within
the bounds of possibility. He argues
that the ether which binds the planets
together with an iron hand is, while
firm and solid, infinitely elastic, and an
ideal medium for the transmission OF

waves produced by ether disturbance
spread out into space, radisting farther
and farther in gigantic circles until swa!-
lowed up in its immensity, like ripples
on the ocean. IL an iron mass be in the
vicinity of these pulsations, il will give
out buzz or hum, as shown in the pass
age Of current through some systems OF
street lighting apparatus for the trans
formation OF high 10 low pressure. The
moon undoubtedly contains its propor-
tiOnate amount of iron, and therefore
the theory is advanced, If We can send
electrical pulsations to the moon, We
can make things hum on its rugged sur
face. Such an experiment would involve

Telegraphv bv induction between
parallel wires about two miles apart
was successfully accomplished recently
in Scotland. The cable connecting the
Isle of Null with Oban broke, and ex-
periments were made before IL was re-
paired. The channel at this point Is
from one and one-quarter 10 two miles
wide, and the distance between the over
head wire on the Isle of Null and the
mainland is almost uniformly two
miles. A gutta-percha insulated wire
was laid along the shore of the mainland
and grounded at each end. \ long in
ductive circuit WAS then arranged, and
messages sent through either wire could
be read on the parallel wire. During
four days 10 regular messages were
sent. besides press message OF l2o
words. The cable repairs were then
completed.
