We have now described how messages may
be sent from Washington 10 Baltimore. and
il may be asked, how is an answer returned!
lmmagine the same machinery as has now
been described, reversed, with the exception
tina. there is no battery in Baltimore, and the
whole is complete for sending and receiving
commu ncations, either way.
We have said that from one OF the poles OF
the battery in Washington, wire extends to
Baltimore, and there enclrcling the iron bar,
returns 10 Washington. The return wire Is
no, absolutely necessary.
From the first commencement OF the WORK
ing OF the Telegraph at Baltimore, bot one OF
the wires upon the poles has been useg. Inc
wire instead of going back TO Washington af-
ter it leaves the coils, descends to the ground,
and is soldered to a copper plate buried In the
earth at Baltimore. At Washington, cop
per plate of the same dimensions is buried in
the cellar Of the Capitol. from which wire is
taken and soldered to the key. So that the
fluid travels upon one wire from Washington
TO Baltimore, and returns TO Washington ihro'
the earth as its conductor.
Prof. Morse has his alphabet so arranged
upon square board, that by drawing slide,
one letter is substituted for another, thus chan
giDg throughout the common alphabet. BY
this means merchant in New York may write
to his correspondent in Philadelphia, without
the possibility Of its being Ineligible to any
one except the individual to whom il Is adj
dressed. Not even the writer upon the instru-
ment in New York, or the attendant IN Phlla.
delphia, can decipher it.
With perfect ease the key can be changed
every day, or at every ten words of the cores
pondence.
This mode Of secre, correspondence is more
sure and safe than that Of ordinary cyphers
used for that purpose. Our limits will not
permit US to 90 into a further description of
other plans which prof. M. has for condensing
much in a little, when long communications
are sent.
This beautiful and wonderful Invention was
made by Prof Morse 10 1882, five years before
any thing of the kind was known in Europe
The Electric Telegraph now used in England,
and invented by Prof. Weatstone, does not
record its communications. The attendant is
obliged TO watch the movement OF several mag
netic needles. upon which are tho letters Of The
alphabet, and as they appear in site TO note
them down. II one should escape his eye, it

superior advantages of Morse's American e.

one, can be easily appreciated.
The Government should possess itself al
once of this triumph of American genius. and
give to every city throughout the Union the
advantages which may be derived from il.

Professor Morse presides at the Electric
Register 10 the Capitol at Washington, and
by manipulating there, writes upon the Regis
ter 10 Baltimore, whilst Alfred Vail, Esq. pre-
sides at the same kind of instrument in this city,
and by similar manipulations, in like manner
writes on the Register at Washington.
The politeness and accommodating DISPOSE
ion of both these gentlemen, 10 giving expla.
nations and affording information to those who

ions, have been spoken of In the highest and
most complimentary terEs.
We find this instrument is now applied 10
hiding the longitude with great accuracy.
The mode is this:--'rhe time of the day will
,e Obtained by an altitude of the sun at two
different places, as Washington and Baltimore,
zach at the precise or same instant. (commu'
aicated by the teegraph). The difference OF
heir reckoning 10 point of time, will express
heir difference of longitude. reckoning de-
yree for every four minutes. To make this
,lainer, suppose two observants take the alt-
ude Of the sun at each extremity OF the wires
# the telegraph. with assistants to attend on
he latter. One observer cries out "Now"
md screws mp his quadrant; Instantly the as
sant touches a wire, and by that single touch
the fact TO the other, who screws

nla,es the time, or finds what is called the
Iour Angle, or what it wants OF noon at each
,lace; the difference of time is the difference of
