"How do you know there isn't?"

"How could there be? You see, I'm not sure whether he really turned in or not, and if he should see you up he'd know something was in the wind. I honestly think you ought to go."

"Well, all right if you feel that way about it," Jack said after a moment's thought. "But you have to promise that you won't get into trouble or I won't go a step."

"Of course I won't," Bob laughed. "Now run along like a good little boy."

He accompanied him as far as the door of the cabin and then went back to the bridge. During the remainder of the night he made frequent rounds of the boat, half expecting to meet the mate again. But in this he was agreeably disappointed. Nor, although he watched carefully, did he see anything which could be taken for a signal.

CHAPTER X.
WHERE IS JOSH?

They weighed anchor shortly after six o'clock. The wind, which had been increasing in strength since four o'clock, was blowing hard from the north-west and the sky looked threatening but Captain Ole assured them that there would be no great storm as the glass had fallen only a couple of points. He proved to be a good weather prophet for, although it began to rain shortly after they had gotten under way, at the same time, the wind began to fall and by noon there was only a light breeze although it was still raining.

At the first opportunity, which did not come until after dinner as Mr. Lakewood, complaining of a severe headache, remained in his bunk until nearly noon, they told their uncle of the mate's actions.

"I get these headaches once in a while," he told the boys as he joined them just as they were sitting down to dinner.
