Memphis daily appeal. [volume] (Memphis, Tenn.) 1847-1886, 1862-05-29

This is made up of the following letters: - P-----
e --.. -- a. - d il S. p----.
- - h h---- t. o. t. Gee.
A. p----- P----- a - - Special dis
patch tF pDsaL Il will be observed that two dots rep
resent well l, but the space between them is
larger the space between words is much larger than
that between letters 1t not little remarkable that
the simple characters of dot the DASH (Which only
prolonged do) the spaces between are capable OF
so many combinations form all the letters all the
figures and the punctuation marks without the employ
of than five characters for any letter, OF
more than six for any numera This way OF repre-
entug letters and numerals will appear complex to the
reader but is really simple that good operator can
-yiteas it ermed-a message more rapidly than the
most expert penmau &C toe other end of tIe line can
| copy 1t oil,
While the instrument the other end where q dis
patch received, making such the above
upon paper. it makes clcSng noise. The sound, of
urse longer aud shorter intervals the dot
the DASH the space succeed each other. In other
words, there il an exact coincidence between the
| Lagtb Of a mark and the time of souud ugu.ar
and unexpected consequence flowed from this fact The
operators became accustomed 10 the sound made by
the instruments that they could distinguish readily
letter from another, nc, tis, closely following the
other was as clearly the letter dots paper
were the letter Operators, therefore be pres
ent time entirely dispense with the paper and the MARKS
a second instrument called sounder, added TO the
first this has the effect of Increasing the volume OF
sound and making the ,ictics 10. der The operator
merely listens the sounds given by the instrument and
he takes them down he hears them In fact, the in
strument talks and he reports words reporter does
the words Of a speech in Congress- There nothing in
all the range Of art thar gOes beyond this
The reader is now in possession of the prncple facts
respecting the practical working OF the telegraph but
there are one or two other which he will feel in
terested in knowing. The telegraph, We have ez'
planned is talking instrument and unucky, like some
other talking instruments, It talks 700 much. Suppose
we wish to send a message Canton, Mississippi, not
only will the instrument at Canton repeat what the
operator at Memphis signals but the Grenada, and
all other instruments between Memphis and Canton will
do the same This il telling much, but means are
known by which the signals be confined to partcu
lar instrument Like old ladies at tea drinking when
one tongue runs all run. The message would keep go
ing to stations beyond Canton but at that place or any
other can be stopped by placing the instrument IN
connection with a wire that communicates with the
ground the gavanc fluid passes into the earth and TIE
instruments at stations beyond that point do not get the
particuar message thus stopped The reader will un
derstand from this how the vulgar saying originated o.
running the thing into the ground" 1t follows from
what we have Just explained that telegraph operators
like doctors lawyers and clergymen, come to the knowl
edge Of many private matters All operators therefore
are taught that messages passing over the line are sa
credy private and every OF them would be covere
with shame if detected in betraying the confidence r'
