"But what about your company's
other Instruments, without which it
is claimed, the new fac-simile system
was unavailable for the cable?" inquired
the interviewer.
sOh, that instrument enables usto use
a good printer on a long deep-sea cable;
our ability to do that facilitates the
use of the new fac-simile apparatus.
Let me explain that on the Atlantic
cables. as now worked, the receiving
instrument is Thompson's siphon-re-
corder. In his system, which is a COM
bination of the inventions Of
Jenkin, Varley and Thompson, the
Morse code Of signals is used, and that
you know is composed of long and short
dashes, and requires three Of such signs
to express the average letter. The
siphon-recorder has to receive from the
cable that number of electrical impulses
and make that number of movements
to represent a single letter. 1t moves
in one direction to indicate a dash, and
whensit swings to the opposite side it
means a dot. 1t leaves upon a moving
paper tape a wavy trail of ink, and as
the sinuosities Of that mark are to the
one side or the other of the middle line
of the paper, so the operator i%nterprets
them as dots or dashes. The addition
of the new duplex system adds about
twenty per cent. only to the sending
capacity Of the cable, and the conditions
essential to that acceleration are so
very delicate, and the electrical
''balancen is so easily disturbed that
the employment Of the duplex appar-
atus has not justified the slightest re-
duction in the tariff of the Anglo
American combination. Now rem
ember that on the average three electri-
cal impulses traverse the cable, and
the siphon-recorder makes three move
ments to signify a single letter at the
receiving end. Substitute our printer
for the siphon-recorder and then each
electrical wave flowing through the
cable will print a letter of the alphabet.
The existing cables charge to-day rs
cents per word. You can easily
reckon that by the use of our printer
alone we will be able to take four times
as many words at one quarter of the
tariff. That is, at 49, cents per word,
using nc heavier battery and trans
hitting the same number of signals, we
can receive four times as many words
and carr the same quantity of dollars
per day as they can. And all this indie
pendent of the much-abused fac-simile
process"
"But is not the use of a printer on an
Atlantic cable of itself wildly absurd?"
"Oh, 1 suppose it is. ! apprehended
the gentlemen whose opinions are given
in the papers would judge the use of a
'%'sounder" on q long deep-sea cable
quite impossible, and as constituting by
ieocli thC biSSCi haiA thO PAopiOh VI
practicable fac-simile cabling, which
the Post told them had been solved.
With regard to what 1 have stated,
here is an opinion from which from you
may quote briefly IL you choose"
The World reporter recognized in
the signature Of the document handed
him the autograph of an electrician of
world wide reputation whose opinion
on such matters ranks second to none
and he copied therefrom the following
startling paragraph:
81 have worked q sounder with your
instruments on n circuit representing
over three thousand miles Of the French
Atlantic cable with seven cells of
Daniels battery.

printer would give a printed Roman
letter for each impulse. y = 1t
