Talking By Telephone Between Chiese'
and New York.


The triumphs Of the speaking tele-
phone within the past seven years have
been q source OF wonder to the world.
For communication on short lines it has
come into general use, especially in this
country. Within the past year some ex-
periments have been made with view
to determine the practicability of the use
Of the telephone in long circuits, only
partial success being achieved where the
lines were more than $50 miles long.
Recently, a corporation known as the
Postal Telegraph Company erected
line between New York and Chicago,
using No. wire, which is made OF
copper, having steel core to stiffe it.
Prof. Elisha Gray, an electrician of New
York, was the protector of this line,
one of the principal objects of which
was experiment on the possibilities Of
long-distance telepboning and to fur
nish a line for the perfecting of the
same. 1t was apparent that com non
iron wires would not not attain tbs re-
suit aimed at. On Monday last the
lines were connected between the Offices
in New York and Chicago and a test
made OF the new copper wire, which
showed resistance of only 1922
"ohms" against 5000 "ohms'' op the
best iron wire and $1,000 Johns on
the average iron wire. A telephone
connection was made and an effort made
to communicate, but without sue, ess.
Sounds could be heard, but the indutt tive
troubles from wires hung on the tine
poles in the city, and in close proximity
to the copper line, made it impossible
to obtain satisfactory results, and it vas
at once determined to make telephone
connection at this end of the line at The
Stock Yards, the New York end be ng
in the company's general office on
broadway.
Yesterday morning Charles E. Scr b.
ner, electrician for the Western Electric
Company, William Hof.master, his u.s.
sistant; +. L. Warner, an employe; John
Young, foreman of the outside depart
ment, and reporter for the Times took
an early train for the Stock Yards,
equipped with all necessary appliances
for the contemplated talk owe. a thou-
sand miles of wire between the cities Of
New York and Chicago. Batteries were
arranged, wires strung and connected
with induction coils, transmitter, key
and receiver, and precisely eleven
o'clock by Chicago time Mr.. Scribner
sent his ''HellorF through the double
Edison transmitter over the thousand.
miles of wire. He promptly received
an answer, which came SO quickly and
so distinctly that he was induced to be-
lieve it could hardly be true that he was
in communication with New York, but

end of the wire Mr.. Hoffmaster played
on the mouth-organ, and E. t. Warner
sang, the report coming back that the
whole was heard distinctly. During
the greater part of the time the con-
versation was perfectly distinct, being
rs plain as through an ordinary tele.
phone in the city. Some difficult
ties were encountered several times
by some one cutting into the line at diff
ferent points, and from the evident
crossing of some telephone wires either
in New York or Cleveland with the
main wire, as other voices could be dis
tinguished at times, and the induction
became SO great that it was necessary
to suspend for the time. The expert
ments, however, were declared to be
entirely satisfactory, results being OBJ.
tanned which were thought to be scarcely
possible. The volume of voice at times
was sufficient to have traversed fully
five hundred miles more of wire, and
yet have been heard distinctly. The
instruments used were the same to both
ends of the wire, and were manufact-
ured in Chicago. The transmitting APP
paratus consisted.of ''double Edison
fl ansmitter," mounted on q single
mouthpiece connected with two induc-
ton coils and with the main line, giving
double the volume of sound of an ordi-
nary transmitter. Two receivers were
used, the ordinary one and the Scribner
head telephone, which is far superior to
the other. Ithas nopermanent magnet,
but simple electro-magnet mounted
in an iron case, with the ordinary dia-
phragm. This is placed in the circuit
with primary induction coil and a
battery, and with the main line. 1t
weighs but two ounces, while the ordi-
nary receiver weighs about pound.
In addition to them, ''key' was at
tached, which cut out the receivers and
cut into circuit the transmitter at will,
and vice versa, thus removing all I'M
necessary resistance in the line. While
talking the receivers were out of the
line, and while receiving the transmit
tiers were out. The experiments will be
