The Story of the Atlantic Telegraph
·
Henry M. Field
280
The
process
of
detecting
faults
is
too
scientific
to
be
detailed
in
these
pages.
We
can
only
stand
in
silent
wonder
at
the
result,
when
we
hear
it
stated
by
Mr.
Varley,
that
the
system
of
testing
is
brought
to
such
a
degree
of
perfection,
that
skilful
electricians
can
point
out
minute
faults
with
an
unerring
accuracy
"even
when
they
are
so
small
that
they
would
not
weaken
the
signals
through
the
Atlantic
cable
one
millionth
part!"
Another
marvellous
result
of
science
was
the
exact
report
obtained
of
the
state
of
that
portion
of
the
cable
now
lying
in
the
sea.
The
electricians
at
Valentia
were
daily
experimenting
on
the
line
which
lay
stretched
twelve
hundred
and
thirteen
miles
on
the
bottom
of
the
deep,
and
pronounced
it
intact.
Not
a
fault
could
be
found
from
one
end
to
the
other.
As
when
a
master
of
the
organ
runs
his
hands
over
the
keys,
and
tells
in
an
instant
if
it
be
in
perfect
tune,
so
did
these
skilful
manipulators,
fingering
at
the
end
of
this
mightier
instrument,
declare
it
to
be
in
perfect
tone,
ready
to
whisper
its
harmonies
through
the
seas.
At
the
same
time,
the
ten
hundred
and
seventy
miles
of
cable
left
on
board
the
Great
Eastern
were
pronounced
as
faultless
as
the
day
they
had
been
shipped
on
board.
With
such
conclusions
of
science
to
animate
and
inspire
them,
the
great
task
of
manufacturing
nearly
seventeen
hundred
miles
of
cable
once
more
began.
And
while
this
work
went
on,
the
Great
Eastern,
that
had
done
her
part
so
well
before,
again
opened
her
sides,
and
the
mysterious
cord
was
drawn
into
her
vast,
dark,
silent
womb,
from
which
it
was
to
issue
only
into
the
darker
and
more
silent
bosom
of
the
deep.
