Lastly, and in quite another direction, the
ph0nograph will perfect the telephone and
reVOlutlOnlZe present systems of telegraphy.
Thai useful invention is now restricted in its
field of operation by reason of the fact that it
is means OF communication which leaves no
record OF its transactions, thus restricting it's
use to simple conversational chit-chat, and
such unimpOrtant details of business as are
not considered of sufficient Importance to re-
cord. Were this different, and our telephone
conversation, automatically recorded, we
should find the reverse of the present status
OF the telephone. 1t would be expressly re-
sorted to as a means of perfect record. 10
writing our agreements we incorporate in the
writing the summing up of our understand
1ng-uslng entirely new and different phrase
OlOgy which we used to express our under
standing of the transaction in it's discussion,
and not infrequently thus begetting perfectly
innocent causes of misunderstanding. Now,
ii the telephone, with the monograph to re-
discussion, we would not only have the full
ard correct text but every word of the whole
matter capable of throwing light upon the
subject. Thus it would seem clear that the
men would find it more advantageous to actu,
ally separate half mile or so in order to dis
cuSS important matters than to discuss them
verbally and then make an awkward attempt
to clothe their understanding in a new Lam
guage: The logic which applies to tranSac-
tons between two individuals in the same
office applies with greater force to two at a
tween them by the telegraph or mail. And
this latter case, in turn, is reinforced by the
demands OF an economy OF time and money
at every mile of increase of distance between
them.
How can this application be made?" will
probably be asked by those unfamiliar with
either the telephone or photograph.
Both these inventions cause a plate or disk
TO vlbrate. and thus produce sound waves in
harmony with those OF the voice of the speak.
er: very simple device may be made by
which the one vibrating disk may be made to
do duty for both the telephone and the phono-
graph, thus enabling the speaker to simultane-
ously transmit and record his message. What
system OF telegraphy can approach that? A
wire, enables the correspondent, if he is pres
ent, to hear it while it is being recorded. Thus
we have mere passage of words for the ac'
ton, but a complete and durable record of
those words as the result of that action. Can
economy OF time or money go further than to
annlhilae time and space, and bottle I'D for
pOSterity the mere utterance of man, without
other effort on his part than to speak the
words?
In order to make this adaptation, it is only
requisite that the monograph shall be made
slightly more sensitive to record, and the tele-
phone very slightly increased in the vibrating
force OF the receiver, and it is accomplished.
Indeed, the Carbon Telephone" Invented
and perfected by the writer, will already wei
nigh effect the record on the monograph: and
as he is constantly improving upon it, to eau e
a more decided vibration of the plate of the
looked for cOincident with the other pract Il
applications of the monograph, and with al
most equal certainty.
The telegraph company of the future-and
that no distant One-Will be simply an Organi-
cation having huge system of wires, central
and sui central stations, managed by skilled
attendants, whose sole duty it will be to keep

tails which seem to arise as obstacles in the
eyes of the groove travelling telegraph man,
welded to existing methods, will wholly dis.

ties of man surmOunt trit1es in order to reap
