"Yes," answered Daley. "Now then, when we top a wave, look sharp--there!"

Daley pointed, and Dave fixed his glance steadily in the direction indicated.

"I see nothing," he said as they went up, down, and up again. "What did you mean?"

"A light--there it is."

"I see it," cried Dave.

"It must be a fire alongshore somewhere, probably the Windjammers' Island," declared Daley.

Dave continued to look. He studied the light each time he was afforded an opportunity. This was only when they climbed some mighty wave, and only for a few seconds.

"You are wrong, Mr. Daley," said Dave finally.

"Wrong about what? It's a light, I tell you."

"Yes, but not a shore light."
