A WONDERFUL INVENTION.
It May RevOIutiOnize TeIegrnphy by
It's Rapfdity and Chenpncss.

From the Baltimore Sun.
Persons interested in electrical devices
were given an exhibition yesterday OF
the working of an invention of Mr.. J. Har-
ris Rogers, of Hyattsville. by which, il
is claimed. 200 words minute can be
transmitted from one point to another
and delivered in printed form at the re-
ceiving office. The invention may revolu-
tionize methods of correspondence.
The device is controlled by the United
States Postal Printing Telegraph Com
pany, which is now operating a line be-
tween Baltimore and Washington, and
which expects to extend it's lines to Phil
adelphia, New York, Boston, and ulti-
mately to all the large cities of the coun-
try.
The apparatus used by this new method
of telegraphy is remarkably interesting.
although it is as yet crude. The two orig
inal machines made by the inventor are
in use, and the type characters by which
the messages are printed were shaped
out with file and set with the aid of a
glass. Negotiations are in progress for
the manufacture of new machines in
which the crudities of those in use at
present will be eliminated.
Visual synchronism and the reduction
OF the Roman alphabet into eight ele>
mentary characters are the two princi-
pal features of Mr.. Rogers invention
BY this method of visual synchronism the
motors att the sending and receiving
points can be controlled and regulated TO
an exact speed. The motors run with a
speed of a thousand revolutions min
ute, and with each revolution a letter
can be made. Averaging words at five
letters each, this gives a speed of two
hundred words minute. The elementary
int tryAF nk n
reduced the alphabet are all straight
lines from which letters are formed and
which makes possible great speed in re-
producing messages.
A message to be sent is first written
on typewriter, which is connected cleo
trically with a punching apparatus
Through the punching apparatus runs a
strip of paper an inch wide As each
letter is struck on the typewriter a hole
or series of holes are punched in the ma
per- the holes running in straight lines
across it, Each hole or series of holes
represents a letter. For instance "T,
is represented by one hole, because If
takes but one of the elementary charac-
tiers to make it, "B' which Is made by
six OF the elementary characters, the lar
gest number required for any one let
ter. is represented on the paper by six
holes. When a letter is finished the
strip is also finished, and the strip is
then put in the transmitting apparatus
and runs over a small metal roller above
which is a series Of small metallic fin
gers which presses upon the strip As
the different holes in the strip of paper
pass under the fingers electrical conneo-
ton is made with the roller and the char
acters represented by the holes are struck
at the other end of the line The move
ment of the apparatus is wonderfully
rapid. That part or which the message
Is printed resembles in some ways the
upper part Of a typewriter.
II is claimed that as much work can ba
done on one line of wire by the Rogers
system as can be done on ten or eve,
twenty wires operated under the Morse
system, and that a letter of POO words
can be sent as cheapy as ten words can
be sent by the old system
