"I hope nothing has happened—that the boat isn't on fire," said Mrs.
Bobbsey to her husband. "That would be terrible!"
"I hardly think that is it," he said. "There may be a small fire, somewhere on the boat, but, even if there is, they have a way of putting it out. I'll go and see what it is. You stay with the children."
But just then, after another clanging of the bell, some one was heard to laugh—the ringing, hearty laugh of a man.
"There!" exclaimed Mr. Bobbsey, "I guess everything is all right. They wouldn't be laughing if there was any danger."
"Let's go to the fire!" cried Bert. "I want to see it!"
"So do I!" chimed in his new chum, Billy, eagerly.
"Oh, can't we see it; whatever it is?" begged Nan.
"First I'll have to make sure there is a fire," replied Mr. Bobbsey. "I hope there isn't. But, if there should be a small one, and the firemen on the boat are putting it out, and if they let us get near enough to see, and if the smoke isn't too thick—"
"Oh, Daddy! Not so many 'ifs' please!" laughed Nan.
The Bobbseys all laughed at this, as did Nell and Billy.
