TELEGRAPHING WITHOUT WIRES.

\ | -" INV OF SOLUTION OF TN
. Great Electrical Problem?
, The promise of coming electrical
, achievements more marvellous than al
that has preceded it is in the air
Electricians who have been admitted e
witness recent experiments in the labor
atory OF Nikola Tesla have come away full,
impressed with the belief that the new
wizard has within his grasp the solution oi
the problem of transmitting intelligence
ana power without the use of wires. Tesla
mas long maintained that this could he
uone. lie declared in public address
Two years ago that his conviction had
grown so strong on that point that he no
longer looked on this plan of energy or
| intelligence transmission as a mere
theoretical possibility, but as a serious
problem in electrical engineering which
must be carried out some day. He has been
working at the problem ever since, and
the invention of his Observation-Disclosures
to be an epoch making machine in the
production of power has been merely an
incident in his patient scientific search for
the period" of the electrical charge of the
| earth.
1t is on the existence of this charge that
the possibility depends of conveying
intelligence without the all of wires and
without respect to distance. Mr.. Tesla
demonstrated some ten years ago that the
edrth could be used as a conductor of
eiectrlc vibration instead of the return
wire long held to be Indispensable. His
slhg'e wire motors gave n convincing
practical demonstration of that fact, and
lei 10 the further conclusion that il is not
necessary to have even a single connection
between the motor and generator, except,
perhaps, through the ground. But to
ulilize electric energy given off into space
or transmitted through tho ground is a
problem somewhat different from that of
procuring at any point of the earth a re-
Spouse TO the disturbance of its electrical
charge at some other point. The one turns
on the question of how good an electrical
conductor the earth may be shown to be.
the other on how nearly 1T is possible 10
ascertain at what period the earth's charge
OF electricity oscillates with respect to an
oppositely electrified system or known
circuit.
Inc scientific basis of the theory that
the earth rs an electrically charged body
insulated in space is to be found in the
accepted Wow of its orgin-that, namely.
OF mechanical separation from other
podes. But the important question was
TO discover what quantity of electricity the |
earth contans-what, in scientific |
language, is its capacity and what is |
the period of vibration. On the answer TO |
thlt depended the possibility of disturbing |
the electrostatic condition of the earth it, |
self or its envroning medium. Mr. Tesla |
has succeeded in raising that pos sibility to /
the rank of n probability. if not of a |
certainty. He has pumped electricity into
the earth, and has secured ''resonance" so
powerful as TO manifest itself in lightning
tl.'shes of considerable length and will
ness. In other words, nc has been able TO
get response through the electrical
vibration which he has impressed on the
eartn from the electric charge which n
disturbed there. The two must, therefore.
have something in common must have
certain degree of raythmical correspond
ence however wide of complete accord.
They my not touch more closely than
would the units which go TO make uD > 600
and 2.O)OOO) If the former'were distributed
over line formed b. the units which 90 TO
make up the latter. But as in this case
one in a hundred would touch. and the
whole be covered at certain fixed intervals.
SO Mr.. Iesla's experiments have led him
far enough to show that he has hit upon
some harmonic correspondence between
The known and the unknown circuit.
When he has succeeded in bringing them
INTO anything like perfect accord lie will |
De able by gentle electric tap TO SEMI a
note vibrating over the whole face of the
Earth, as 1t lay before him like the tight
sned skin of n drum.-BJst9n Herald.
