The Story of the Atlantic Telegraph
·
Henry M. Field
58
It
was
to
the
honor
of
the
American
navy,
to
have
led
the
way
in
these
deep-sea
soundings.
But
after
this
second
voyage
of
exploration,
Mr.
Field
applied
to
the
British
Admiralty,
"to
make
what
further
soundings
might
be
necessary
between
Ireland
and
Newfoundland,
and
to
verify
those
made
by
Lieutenant
Berryman."
It
was
in
response
to
this
application
that
the
Government
sent
out
the
following
year
a
vessel
to
make
still
another
survey
of
the
same
ocean-path.
This
was
the
steamer
Cyclops,
which
was
placed
under
Lieutenant
Commander
Joseph
Dayman,
of
the
British
navy,
an
officer
who
had
been
with
Captain
Sir
James
Ross
when
he
made
his
deep-sea
soundings
in
the
South
Atlantic
in
1840,
where
he
attained
a
depth
of
twenty-six
hundred
and
sixty-seven
fathoms;
and
who
by
his
intelligence
and
zeal,
was
admirably
fitted
for
the
work.
To
speak
now
of
this
third
survey,
is
anticipating
in
time.
But
it
will
serve
the
purpose
of
unity
and
clearness
in
the
narrative,
to
include
all
these
deep-sea
soundings
in
one
chapter.
He
was
directed
to
proceed
to
the
harbor
of
Valentia
in
Ireland,
and
thence
to
follow,
as
nearly
as
possible,
along
the
arc
of
a
great
circle
to
Newfoundland.
"The
soundings
for
the
first
few
miles
from
the
coast
should
be
frequent,
decreasing
as
you
draw
off
shore."
These
orders
were
thoroughly
executed.
Every
pains
was
taken
to
make
the
information
obtained
precise
and
exact.
Whenever
a
sounding
was
to
be
taken,
the
ship
was
hove
to,
and
the
bow
kept
as
nearly
as
possible
in
the
same
spot,
so
that
the
line
might
descend
perpendicularly.
This
was
repeated
every
few
miles
until
they
had
got
far
out
into
the
Atlantic,
where
the
general
equality
of
the
depths
rendered
it
necessary
to
cast
the
line
only
every
twenty
or
thirty
miles.
Thus
the
survey
was
made
complete,
and
the
results
obtained
were
of
the
greatest
value
in
determining
the
physical
geography
of
the
sea.
