The Story of the Atlantic Telegraph
·
Henry M. Field
325
These
different
experiments
revealed
some
secrets
of
the
ocean.
Its
bottom
proved
to
be
generally
ooze,
a
soft
slime.
When
the
rope
went
down,
one
or
two
hundred
fathoms
at
the
end
would
trail
on
the
sea
floor;
and
when
it
came
up,
this
was
found
coated
with
mud,
"very
fine
and
soft
like
putty,
and
full
of
minute
shells."
But
it
was
not
all
ooze
at
the
bottom
of
the
sea,
even
on
this
telegraphic
plateau.
There
were
hidden
rocks--perhaps
not
cliffs
and
ledges,
but
at
least
scattered
boulders,
lying
on
that
mighty
plain.
Sometimes
the
strain
on
the
dynamometer
would
suddenly
go
up
three
or
four
tons,
and
then
back
again,
as
if
the
grapnel
had
been
caught
and
broken
away.
Once
it
came
up
with
two
of
its
hooks
bent,
as
if
it
had
come
in
contact
with
a
huge
rock.
At
one
time
it
brought
up
in
the
mud
a
small
stone
half
the
size
of
an
almond;
and
at
another
a
fragment
as
large
as
a
brick.
This
was
a
piece
of
granite.
