HOW CABLE MESSAGES ARE RE-
CElVED.

CElVED.
Until the fore part Of November the
French cable, having its terminus at
North Eastman, Mass, employed the
flash system of signaling. Now the
cable is worked duplex on the Sterns
system, saws the Journal of the Tele-
graph, using an automatic recorder, by
which the messages are received IN INK
on narrow strip of paper. :.
Bv tho system which has been dis
placed the messages were spelled OUT
bv flashing ray of light back ana
forth across standard line, the right
and left flashes corresponding with the
dots and dashes OF the ordinary tele-
graphic alphabet.
In this system the light Is flashed BY
reflection from an extremely light mir
ror, which is turned to right and lett
by the opposing influences OF POSITIVE
land negative impulses. This system
has the advantage of being operated
with very slight electric Impulses, nut
also the disadvantage of leaving no
permanent record.
, To secure the latter very important
end the recording instrument has been
: adopted. The press dispatch announc-
: ing the change states that in the new
r recorder the ink is discharged by the
/. agency of electricity and "not by capii-
t lary attraction as in other cable recor'
