“Humph!” said Michel Ardan, “it is not easy; we are in the train, and the guard’s whistle will sound before twenty-four minutes are over.”

“Twenty,” said Nicholl.

“Everything is in its place,” said Barbicane. “We have now to decide how we can best place ourselves to resist the shock. Position cannot be an indifferent matter; and we must, as much as possible, prevent the rush of blood to the head.”

“Just so,” said Nicholl.

“Then,” replied Michel Ardan, ready to suit the action to the word, “let us put our heads down and our feet in the air, like the clowns in the grand circus.”

“No,” said Barbicane, “let us stretch ourselves on our sides; we shall resist the shock better that way. Remember that, when the projectile starts, it matters little whether we are in it or before it; it amounts to much the same thing.”

“Do you approve of my idea, Nicholl?” asked Barbicane.
