"You sure?"

"I think so. I swung around her bow, and unless I've turned again, we must be right."

"Well, I hope so, but I guess it'll be safe to take the oars now," Bob said as he picked them up from the bottom of the boat and slipped them into the locks.

The fog was now almost as thick as before and they could see only a very short distance, but Bob rowed with all his might while Jack helped with the paddle.

"Ought to be about there, don't you think?" the latter asked after a few minutes had passed.

"If we're going in the right direction," Bob replied.

"Don't you think we are?"

"Frankly I haven't the least idea."

"You haven't?" There was a note of alarm in the question.

"No, I'm completely turned around," Bob confessed.
