"Make a smudge of smoke on board here. Smoke can be seen a long way, and maybe it will bring us help."
"We'll try it," decided Bob.
They went to bed, but they did not sleep as well as the night before. Morning came, and with it a dense fog.
"That's too bad!" exclaimed Frank. "No one will see us now, and we may be in danger of a collision."
"Can't we do anything?" asked Sammy.
"Yes, we can blow a horn every once in a while, if we can find one, and ring the ship's bell. That's what they always do in a fog."
"Then let's do it!" suggested Sammy.
So while the fog hung about them—a damp, white blanket—the boys tooted the horn, and clanged the bell. This was to warn other vessels not to run into them.
But, though they listened sharply, they heard no sounds that would indicate another vessel to be near them. They seemed all alone on the ocean, and they were more discouraged than before.
True they were not cold, for the day was warm, and they had plenty to eat. They were in a good, stout vessel, too, and in no great danger, unless another storm should come up.
