On board the Porpoise there was great excitement. Washington, with Andy, Tom, Bill and Jack came running from the engine room.

"What is it?" cried Jack.

"I don't know," answered the professor as calmly as he could. "We'll soon see, however."

He switched on the searchlight and peered from the conning tower.

"Can you see anything?" asked Andy, anxiously.

"I can," announced the inventor.

"What?"

"Land," replied Mr. Henderson. "We've hit the coast."

"I hope we ain't done no damage," put in Washington.

"Do you mean to the coast or to us?" asked the professor, with a smile. "I guess there isn't much danger in ramming the shore excepting to the Porpoise. However, we do not seem to be in any immediate trouble."
