Cast
iron
is
very
brittle
,
though
,
"
replied
Morgan
.
272
"
Yes
,
but
it
possesses
great
resistance
.
I
will
now
ask
our
worthy
secretary
to
calculate
the
weight
of
a
cast-iron
gun
with
a
bore
of
nine
feet
and
a
thickness
of
six
feet
of
metal
.

In
a
moment
,

replied
Maston
.
Then
,
dashing
off
some
algebraical
formulae
with
marvelous
facility
,
in
a
minute
or
two
he
declared
the
following
result
:

"
The
cannon
will
weigh
68,040
tons
.
And
,
at
two
cents
a
pound
,
it
will
cost
--

"
Two
million

hundred
and

Maston
,
the
major
,
and
the
general
regarded
Barbicane
with
uneasy
looks
.

"
Well
,
gentlemen
,
"
replied
the
president
,
"
I
repeat
what
I
said
yesterday
.
Make
yourselves
easy
;
the
millions
will
not
be
wanting
.

With
this
assurance
of
their
president
the
committee
separated
,
after
having
fixed
their
third
meeting
for
the
following
evening
.

There
remained
for
consideration
merely
the
question
of
powders
.
The
public
awaited
with
interest
its
final
decision
.
The
size
of
the
projectile
,
the
length
of
the
cannon
being
settled
,
what
would
be
the
quantity
of
powder
necessary
to
produce
impulsion
?

It
is
generally
asserted
that
gunpowder
was
invented
in
the
fourteenth
century
by
the
monk
Schwartz
,
who
paid
for
his
grand
discovery
with
his
life
.
It
is
,
however
,
pretty
well
proved
that
this
story
ought
to
be
ranked
among
the
legends
of
the
middle
ages
.
Gunpowder
was
not
invented
by
any
one
;
it
was
the
lineal
successor
of
the
Greek
fire
,
which
,
like
itself
,
was
composed
of
sulfur
and
saltpeter
.
Few
persons
are
acquainted
with
the
mechanical
power
of
gunpowder
.
Now
this
is
precisely
what
is
necessary
to
be
understood
in
order
to
comprehend
the
importance
of
the
question
submitted
to
the
committee
.
