The sailors began leaping from the ship to a large rock that rose out of the water about half a mile off. Their agility was marvellous, and Flathootly covered himself with glory in leaping over the ship hundreds of feet in the air and alighting on the same spot on deck again.
Their officers and scientific staff remained on deck as became their dignity, although tempted to try their agility like the sailors.

How could I turn fifteen summersaults at wance if I was any weight? That shows yer weighing machine is all wrang again."
"How can you stand on the deck if you are no weight?" inquired the professor.
"Why, I'm only pressing me feet on the boards," said the Irishman; "look here!" So saying, he leaped from the yard and revolved in the air at least twenty times before alighting on the deck.
