At the word, Jim pushed back the window and poking his head out took a good long look.

"Overhangs the water," exclaimed Jim as he pulled back.

"Let me have a peek," said the engineer, and looking down he saw the waves rushing in against the black rock of the cliff a hundred feet or more beneath. When the water withdrew there was a wet stretch of sandy cove, and then the waves came in with a foaming rush.

"It's pretty near high now," said Berwick, as he pulled his head in.

"I don't think it would be much of a trick to get around that projection of the cliff to the beach," remarked Jim.

"Maybe," replied Berwick noncommittally, with a slight shrug of his shoulders.

"You can swim like a fish," put in Jim who had noted the shrug of his comrade's shoulders.

"But I was thinking of you, my poor friend," replied the engineer. "What would become of you if the hungry ocean should seize upon you with its white and foaming teeth?"

"Oh, I'd wade out," remarked Jim nonchalantly.

"Humph," grunted Berwick; "by the way, Jim, I think I can find something of real interest here."
