The
two
ends
of
the
wire
were
connected
with
an
electro-magnet
fastened
to
a
vertical
wooden
frame.
In
front
of
the
magnet
was
its
armature,
and
also
a
wooden
lever
or
arm
fitted
at
its
extremity
to
hold
a
lead-pencil....
I
saw
this
instrument
work,
and
became
thoroughly
acquainted
with
the
principle
of
its
operation,
and,
I
may
say,
struck
with
the
rude
machine,
containing,
as
I
believed,
the
germ
of
what
was
destined
to
produce
great
changes
in
the
conditions
and
relations
of
mankind.
I
well
recollect
the
impression
which
was
then
made
upon
my
mind.
I
rejoiced
to
think
that
I
lived
in
such
a
day,
and
my
mind
contemplated
the
future
in
which
so
grand
and
mighty
an
agent
was
about
to
be
introduced
for
the
benefit
of
the
world.
Before
leaving
the
room
in
which
I
beheld
for
the
first
time
this
magnificent
invention,
I
asked
Professor
Morse
if
he
intended
to
make
an
experiment
on
a
more
extended
line
of
conductors.
He
replied
that
he
did,
but
that
he
desired
pecuniary
assistance
to
carry
out
his
plans.
I
promised
him
assistance
provided
he
would
admit
me
into
a
share
of
the
invention,
to
which
proposition
he
assented.
I
then
returned
to
my
boarding-house,
locked
the
door
of
my
room,
threw
myself
upon
the
bed,
and
gave
myself
up
to
reflection
upon
the
mighty
results
which
were
certain
to
follow
the
introduction
of
this
new
agent
in
meeting
and
serving
the
wants
of
the
world.
With
the
atlas
in
my
hand
I
traced
the
most
important
lines
which
would
most
certainly
be
erected
in
the
United
States,
and
calculated
their
length.
The
question
then
rose
in
my
mind,
whether
the
electro-magnet
could
be
made
to
work
through
the
necessary
lengths
of
line,
and
after
much
reflection
I
came
to
the
conclusion
that,
provided
the
magnet
would
work
even
at
a
distance
of
eight
or
ten
miles,
there
could
be
no
risk
in
embarking
in
the
enterprise.
And
upon
this
I
decided
in
my
own
mind
to
SINK
OR
SWIM
WITH
IT.'
