"What has happened to the ship?" cried the professor. "Is it a tidal wave?"
"I was on deck," panted Jack. "I saw the white thing! I crept up on it! All at once the ship rose in the air!"

"Shut off the engine!" Mr. Henderson called down to Washington, who hurried to obey.
"What has happened?" asked Andy, rushing towards him.
"We have run upon an island," answered the professor. "This is the worst thing that has yet happened to us."
"What sort of an island is it that shoots you up in the air?" asked the old hunter.
"It's hard to say," replied Mr. Henderson. "We will have to wait until morning to find out."
