"No danger of that, if I know Helen, and I think I do," remarked Frank.
"And as for Minnie, I think she would be apt to spy you a mile away, and wave," observed Paul, hastily, in order to hide his own confusion.
"Two men in a boat!" sang Frank, at which both laughed.
"Why, we've come over three miles already, and Bellport isn't much more than that below. Do you think they would venture this far?" asked the other, presently.
"Certainly not below the island around that bend. I've never known Helen to go beyond that in her exercise. She's unusually fond of a boat, as you understand, and particularly this boat," Frank went on.
"Oh! rats, any boat would answer just as well," but all the same Paul chuckled as if pleased at this suggestion of the brother of Helen.
But even Frank was getting a bit worried now, because they had discovered no signs of the girls.
"What's that over yonder near the shore?" asked Paul, suddenly.
"Where? Oh! yes, I see what you mean. Looks like a sunken boat of some kind. I suppose an old broken craft that's been cast loose, and gone under with the ice last winter," remarked Frank, carelessly.
