for few minutes neigenty the in its pro-
duction
"And first will take the megaphone light and pretty
instrument that be of metal or of other material
Inc shape IS cone One end that in which you speak is
large The one which Ellen has about foot diameter
at the larger end and three onehalf in LENGTH This n
entirely composed of brass The smaller end HAVING an omen
ing OF about hveeghts of nch connected by rubber
tube with the recorder composed of metal an opening
leading to that of the recorder which called the daam
about one and onequarter inches in diameter composed of
glass; thin and elastic.
{" To the of this daram is attached charm ooss :,
strument by which sound is enabled to make a record
Inc record is made on cylinder about two and
hches diameter and four inches in length composed of parane
and wax This cylinder placed upon and caused to
rotate Immediately beneath the recorder AS the cylinder
rotaes the recorder moved by endless in line par
allel to the axis of the cylinder
"1n Eens graphophone the power is obtained from
long steel spring like the main spring watch but much
larger And, like watch or clock has to be wound up if
used, from time to time
In order to form record wax cylinder the GLASS
instrument which joined to the of the dafram is per-
mited to rest the cylinder which caused to rotate at
uniform speed
The Sound produced outside of the Meoanbore br+ r
by uttered into it.
All the graphophone records be uttered into the
megaphone.
Every sound is endowed with the principle of motion If
it was not it wouldn't be of any use But now it moves in all
directions unless restrained From the meqaphone
is conducted through short the diafram to which
the stylus attached which makes the upon the paa
fine and wax This tube is supplied with Joint SO that the
recorder cylinder with uniform, nrecsr
from its weight.
The machine being this cylinder revolves somewhat
swiftly at the time the recorder including the daram
with stylus carried along parallel to the axis of the
cylinder The result OF this spiral groove form upon
the cylinder which the are constantly dronDno
thus forming these ndentures musical instruments which
can be seen in the groove
The CYLINDER said, pass under the stylus at
each rotation"
Yes she replied The indentures of the granhonbone
record not sound but made the sound which is
uttered into the megaphon way to the recorder
But how do sounds manufacture the ndentures of graph
ophone record2" asked.
By movement" she answered Has not the old Pine
watched the of the various machinery of the
world, and noticed that only by movement is anything
accomplished? There is other way If everything re-
NAMED stationary there would be nothing done 1t is the
movement of sounds Something they always and always
exer that creates these ndenure the parane wax
which, thrown into action throw off precisely the sound
sounds which created them
But can Ellen tell how they do ths?"
She thinks she can AS she has said, they do it by move
ment and this that of the which enter the
megphone and thence conducted cylinder of parane
and wax And these sounds be of any character is
any sound might enter the megaphone But however made
(whatevr is their character and that will be decided what
they representa- they all sounds, all in notion all
representing particular KIND OF sound and therefore have
particular movement and particular shape both of which
accordance with the laws of will or may be shaped
INTO certain FORM which then becomes instrument as
much piano, and if struck by appropriate instrument
will utter its sound the piano any other similar
instrument when struck the sound made to utter
And in the of the indenure that of the piano
the particular result obtained due the particular shape of
the instruments"
But why does particular shape produce particular
in either of these nstruments?"
has befor che
she has proved it, so that it explains itself"
Again has the Pine noticed that the principle of
Like producing Like very throughout universe
