The Story of the Atlantic Telegraph
·
Henry M. Field
148
But
it
was
no
time
for
useless
regrets.
Once
more
the
cable
was
joined
in
mid-ocean,
and
dropped
to
its
silent
bed,
and
the
Niagara
and
the
Agamemnon
began
to
steam
away
toward
opposite
shores
of
the
Atlantic.
This
time
the
experiment
succeeded
better
than
before.
The
progress
of
the
English
ship
is
thus
reported:
"At
first,
the
ship's
speed
was
only
two
knots,
the
cable
going
three
and
three
and
a
half,
with
a
strain
of
fifteen
hundred
pounds.
By
and
by,
however,
the
speed
was
increased
to
four
knots,
the
cable
going
five,
at
a
strain
of
two
thousand
pounds.
At
this
rate
it
was
kept,
with
trifling
variations,
throughout
almost
the
whole
of
Monday
night,
and
neither
Mr.
Bright,
Mr.
Canning,
nor
Mr.
Clifford
ever
quitted
the
machines
for
an
instant.
Toward
the
middle
of
the
night,
while
the
rate
of
the
ship
continued
the
same,
the
speed
at
which
the
cable
paid
out
slackened
nearly
a
knot
an
hour,
while
the
dynamometer
indicated
as
low
as
thirteen
hundred
pounds.
This
change
could
only
be
accounted
for
on
the
supposition
that
the
water
had
shallowed
to
a
considerable
extent,
and
that
the
vessel
was,
in
fact,
passing
over
some
submarine
Ben
Nevis
or
Skiddaw.
After
an
interval
of
about
an
hour,
the
strain
and
rate
of
progress
of
the
cable
again
increased,
while
the
increase
of
the
vertical
angle
seemed
to
indicate
that
the
wire
was
sinking
down
the
side
of
a
declivity.
Beyond
this,
there
was
no
variation
throughout
Monday
night,
or,
indeed,
through
Tuesday."
