"
No
,
certainly
not
,
"
replied
Barbicane
;
"
we
require
an
enormous
initial
velocity
;
and
you
are
well
aware
that
a
shot
quits
a
rifled
gun
less
rapidly
than
it
does
a
smooth-bore
.
"
"
True
,
"
rejoined
the
major
.
The
committee
here
adjourned
for
a
few
minutes
to
tea
and
sandwiches
.
On
the
discussion
being
renewed
,
"
Gentlemen
,
"
said
Barbicane
,
"
we
must
now
take
into
consideration
the
metal
to
be
employed
.
Our
cannon
must
be
possessed
of
great
tenacity
,
great
hardness
,
be
infusible
by
heat
,
indissoluble
,
and
inoxidable
by
the
corrosive
action
of
acids
.
"
"
There
is
no
doubt
about
that
,
"
replied
the
major
;
"
and
as
we
shall
have
to
employ
an
immense
quantity
of
metal
,
we
shall
not
be
at
a
loss
for
choice
.
"
"
Well
,
then
,
"
said
Morgan
,
"
I
propose
the
best
alloy
hitherto
known
,
which
consists
of
one
hundred
parts
of
copper
,
twelve
of
tin
,
and
six
of
brass
.
"
"
I
admit
,
"
replied
the
president
,
"
that
this
composition
has
yielded
excellent
results
,
but
in
the
present
case
it
would
be
too
expensive
,
and
very
difficult
to
work
.
I
think
,
then
,
that
we
ought
to
adopt
a
material
excellent
in
its
way
and
of
low
price
,
such
as
cast
iron
.
What
is
your
advice
,
major
?
"
"
I
quite
agree
with
you
,
"
replied
Elphinstone
.
"
In
fact
,
"
continued
Barbicane
,
"
cast
iron
costs
ten
times
less
than
bronze
;
it
is
easy
to
cast
,
it
runs
readily
from
the
moulds
of
sand
,
it
is
easy
of
manipulation
,
it
is
at
once
economical
of
money
and
of
time
In
addition
,
it
is
excellent
as
a
material
,
and
I
well
remember
that
during
the
war
,
at
the
siege
of
Atlanta
,
some
iron
guns
fired
one
thousand
rounds
at
intervals
of
twenty
minutes
without
injury
.
