Thomas A. Edison, Jr., expects soon

special inventions of his own. teie.
phone communication between Europe
and America is commercially feasible
The experiments thus far con.
Quoted" said Mr.. Edison, have been
so satisfactory that we are negotiatine

must meet. What cable we have in

be no further reason for secrecy.
OF course, to lay cable simply foI
experimental purposes would be toe
expensive. There is no doubt that oul
present efforts will result in placins
at our disposal a cable adapted to oul
requirements.
THE special transmitters and re-
ceivers for submarine telephoning will
be completed in six weeks. By the
use of these transmitters and receivers
and of other devices, we feel confident
that we can overcome the many OBJ.
.stacles that have hitherto made inter
national communication by telephone
seem impracticable.
MY father, you will remember, stat
ed that, by erecting stations every
hundred miles, the thing could be
done; but as he explained, this sys-
TEN would be so expensive that it was
out of the question. BY our sys-
TEN, however, probably not more
than one station would be necessary.
and could it be arranged to carry the
wire far up the American coast, this
station could be built on land.
eff necessary to have the station at
sea- it would be simply great caisson
sunk deep in the water. At the sta
tion the sound could be transferred
and augmented by a mechanical de-
vice.
the general principle of the trans
mitters and receivers can, think, be
understood readily, though shall not
attempt to explain their mechanism.
One of the chief obstacles to be over
come is what is known as static induc-
ton. 1t is, so to speak, a sort of pull
exerted by the magnetic pole, and it
impedes and interferes with the cur
rent on the cable.
Elm telephoning, it's effect is to pro-
duce an elongation of syllables, and
finally, where the distance is great, the
sound 0f conversation ic oop, NH; N o
like prolonged groan; the words are
blended and indistinguishable.
THE old machines fail to perform
the required work quickly enough.
This difficulty we overcome by adding
to the transmitter device which null
tiplies the vibrations. Suppose, for
example, the word and should be re-
peated into the transmitter at the rate
of 100 times a minute. The device
would increase the number of ands to
200 minute, and in spite of the static
induction the word and would still be
repeated too many times in a minute
by the receiver across the ocean.
Therefore, in order to make the
sound ineligible, the nu nber of vibra-
lions recorded by the receiver must be
reduced, and this is done by mechan-
icaI device attached to the receiver
which diminishes the vibrations to the
proper number. The result is that the
word comes to the ear clear and sharp
The elongation is entirely overcome.
1--WE are also able to oppose the sta
tic induction by a device through
which it is counterbalanced by the en-
ployment of an opposing force.
at is our purpose to make our neXi
tests as severe as possible in order
that we may be sure of our ground

Mr.. Edison explained that the length
of cable required between America and
Europe could be greatly shortened b!
anchoring it to the submits of the
ridges of the ocean bottom instead o.
letting it fall into all the deep depres
sions.
"gSfhaps, as 4 am an inventor" Mr.
F0igun continued, II may seem to b
.oyer-enthusiastic, but sincerely be
,lieve that submarine telephoning i
bound to take the place of the subma
.rine telegraph in a great measure, be
