Automatic Devices for Gables and
Land Lines.
The changes made in the ocean ca
bic equipment consist principally in
the substitution of automatic trans
mission for the ordinary method Of
hand signalling previously in vogue.
The precise and uniform character Of
the currents transmitted by these au-
tomato machines not only makes the
work OF transcription less difficult, but
enables the cables to be operated at
a higher rate of speed. An innovation
of considerable practical Importance
has been recently made in connection
with this particular branch Of the
Western Union service by the employ
nent Of an exceedingly simple and eff
ticient electrical perforating machine
which admits Of the slip being
punched" with a degree of ease not
heretofore attained, and at a rate OF
speed greatly in excess Of that posi-.
BILE with the ordinary style of punch
ing apparatus.
Direct communication between the
most distant points on land lines is one
of the highly important practical re-
suits of the use of a repeating relay
which the writer had the honor of first
introducing upon the Western Union
lines some two years ago. 1t Is de-
vice that admits of the direct recep-
ton and transmission Of currents from
one line to another, differing in this
respect from the ordinary repeater ar
rangement, which can only effect the
necessary work through the interposi-
ton at each repeating station OF GER
tain local apparatus having a pen
chant for getting out Of order" 1t is
now possible to work direct over prac-
tically unlimited distances at increased
speed, the received signals being much
more clear than any heretofore OBJ
tanned under such conditions, and cir
cults from, New York to. San Francis
co, Cuba, Galveston, Tex; Hearts
Content, Newfoundland, and host Of
other places far and near are already
equipped with the new repeating de-
vice.
Perhaps the greatest achievement In
the way of Geographic development,
and one calculated to bring about rad
zeal changes in existing methods of
working Is that connected with the
printing telegraph art, which for years
past has been struggling hard to find
favor with the telegraphing public,
and to firmly establish itself among
the various systems employed in ordi-
nary commercial telegraphy.
A great number of printing tele-
graph systems have been tried and
found wanting. Two or three have
gained a foothold by proving more or
less successful in experimental work
or under actual working conditions,
but all have grave defects that seri-
ously impair their usefulness, and I'M
der such circumstances nothing in the
way of rapid extension of such sys-
TENS could be looked for. A system
involving essentially the use of type
writer for transmitting, and another
for receiving the messages, was found
to be highly desirable, not only be-
cause such an arrangement would
DEdCIjCdlly uOuUlG tllC Cell1 ydllS3 ShpctSA-
ty of wires over which the system was
operated, but the use of high skilled
labor and complicated machinery could
be more or less dispensed with, Incl
dental advantages being gained in the
way of securing perfect record of all
desirable characters, and in less time
withal than that possible through the
medium of any system in which per-
forated tape forms part Of the trans
hitting arrangement.
Such a system as that above out
lined has been developed by the au
thor, and now, in practical operation
over the Western Union lines between
New York and Buffalo, with results SC
entirely satisfactory that as soon as
the necessary arrangements can be
made circuits in various otheas direc
lions win be equipped with the new
printing rnechaf1ism.-J. c. Barclay in
