Mr.. Bartlett has in charge the con-
struction of the lines of the new Postal
Telegraph, of which some account was
given in the Times few days ago. He
came to this city the other day and gave
an interesting account of TIE progress the
company is making and the way in which
it purposes to transact business. 1t is
now building line between New York
and Chicago and poles are up along the
whole distance, with the exception OF
few gaps aggregating about fifty miles,
which the contractors are rapidly filling.
The wires are being strung as rapidly rs
they can be manufactured at the compa
ny's works, for one of the peculiarities of
the Postal Telegraph Company is that it
makes its own wire-a steel core the size
Of large knitting-needle clectro-plated
with copper till it is nearly as thick as a
lead pencil When the New York-Chica-
90 line is finished, which will be some
time next month, a second line will be
started to run to Philadelphia, Baltimore
and Washington, and third TO 60 TO
Boston. In the course of next year it is
proposed TO reach all the principal cities
east Of the Mississippi, and the company's
contract with the new French Cable
Company obliges it have it wires in New
Orleans in fifteen months from Septcm-
Der, 1882. The cable company, which is
organized in France, with a capital of
$ll 100000, is laying a cable across the
Atlantic, by way of the coast of Portugal
and the Azores Islands. From the
Azores two cables will be laid; one to IIa-
vana and Aspinwall, where it viii con-
meet with the South American system Of
lines, and thc other to point on the
shore OF Long Island Sound, where it will
connect with the lines of the Postal Tel
egraph Company. The poles for the land
line to this point arc already in place.

1t is promised that some marvellous re-
suits will be shown when these lines are
finished. Not only will the wires be
worked" through from New York to
Chicago without repeating, feat practi-
cally impossible with iron wires worked
by the Morse or any other system, but
the rapidity of Transmission will be great
ly increased. The average time required
for sending a message between the two
cities now is fifteen nutes, but with
the copper wires 1t will be only few
seconds. why" said Mr.. Bartlett, with
enthusiasm, "if could get that far ahead

1t is claimed that the application of
the duplex and quadruplex patents to the
Morse system is practicable only on short
circuits; that, in fact, the latter will work
properly but little farther than the dis
tance between New York and Philadel-
phia, while the Gray system, which is
owned blythe Postal Telegraph Company,
multipliee an iron wire nine times over
a three hundred mile circuit, and cop
per wire 10 any extent and over any dis
tance. Practically, however, it has only
been made TO work up to nine messages
at once on a single copper wire. The
base of the system is that difference in
vibrations which makes musical tones.
1t is well known that if two strings on
different violins are tuned in exactly the
same key bow drawn across one will
cause both to sound, and something of
the same kind sapplied 10 the telegraph.
4 little instrument toned in a certain
key is attached to ore end of the wire
and the message sent through it is re-
ceived b. another instrument similarly
toned, at the other end. These two in
struments work in harmony and are not
interfered with at all by the working of
another, or, theoretically, of any number
of other gets, over The same wire at the
same time. There is something in the
electrical vibrations that keeps their
notes distinct
