Heroes of the Telegraph

His
researches
on
the
dynamo
caused
him
to
devise
what
he
calls
an
'harmonic
engine.'
It
consists
of
a
tuning-fork,
kept
in
vibration
by
two
small
electro-magnets,
excited
with
three
or
four
battery
cells.
It
is
capable
of
working
a
small
pump,
but
is
little
more
than
a
scientific
curiosity.
With
the
object
of
transforming
heat
direct
from
the
furnace
into
electricity,
he
also
devised
a
'pyro-electric
generator,'
but
it
never
passed
beyond
the
experimental
stage.
The
same
may
be
said
for
his
pyro-electric
motor.
His
dynamo-electric
motors
and
system
of
electric
railways
are,
however,
a
more
promising
invention.
His
method
of
telegraphing
to
and
from
a
railway
train
in
motion,
by
induction
through
the
air
to
a
telegraph
wire
running
along
the
line,
is
very
ingenious,
and
has
been
tried
with
a
fair
amount
of
success.
At
present
he
is
working
at
the
'Kinetograph,'
a
combination
of
the
phonograph
and
the
instantaneous
photograph
as
exhibited
in
the
zoetrope,
by
which
he
expects
to
produce
an
animated
picture
or
simulacrum
of
a
scene
in
real
life
or
the
drama,
with
its
appropriate
words
and
sounds.
Edison
now
resides
at
Llewellyn
Park,
Orange,
a
picturesque
suburb
of
New
York.
His
laboratory
there
is
a
glorified
edition
of
Menlo
Park,
and
realises
the
inventor's
dream.
The
main
building
is
of
brick,
in
three
stories;
but
there
are
several
annexes.
Each
workshop
and
testing
room
is
devoted
to
a
particular
purpose.
The
machine
shops
and
dynamo
rooms
are
equipped
with
the
best
engines
and
tools,
the
laboratories
with
the
finest
instruments
that
money
can
procure.
There
are
drawing,
photographic,
and
photometric
chambers,
physical,
chemical,
and
metallurgical
laboratories.
There
is
a
fine
lecture-hall,
and
a
splendid
library
and
reading-room.
He
employs
several
hundred
workmen
and
assistants,
all
chosen
for
their
intelligence
and
skill.
In
this
retreat
Edison
is
surrounded
with
everything
that
his
heart
desires.
In
the
words
of
a
reporter,
the
place
is
equally
capable
of
turning
out
a
'chronometer
or
a
Cunard
steamer.'
It
is
probably
the
finest
laboratory
in
the
world.
