major.

"That would be superb, however! said J.T. Maston.

"But impracticable," answered Barbicane. "No, I think of casting this
engine in the ground itself, binding it up with wrought-iron hoops, and
then surrounding it with a thick mass of stone and cement masonry. When
it is cast it must be bored with great precision so as to prevent
windage, so there will be no loss of gas, and all the expansive force of
the powder will be employed in the propulsion."

"Hurrah! hurrah!" said Maston, "we have our cannon."

"Not yet," answered Barbicane, calming his impatient friend with his
hand.

"Why not?"

"Because we have not discussed its form. Shall it be a cannon, howitzer,
or a mortar?"

"A cannon," replied Morgan.

"A howitzer," said the major.

"A mortar," exclaimed J.T. Maston.

A fresh discussion was pending, each taking the part of his favourite
weapon, when the president stopped it short.
