Their call, however, was unanswered and at last both boys were convinced that they had lost the location of the motor-boat.

“There isn’t anything for us to do except to wait until morning,” said Fred at last.

“Yes, there is, too,” said John. “You let me take those oars. I’m not going to stay here. I’m sure we’ll find the Gadabout or something just as good.”

“That doesn’t trouble me as much as somebody finding us.”

“What do you mean?”

“Why, suppose some boat runs us down in the dark?”

“We can hear a boat two miles away.”

“If we are awake,” suggested Fred.

“We’ll be awake all right, at least I shall, for I’m going to keep rowing.”

“That wouldn’t be my plan,” said Fred, nevertheless relinquishing his position to his friend. “I think we are just as well off to wait where we are and when the sun rises we’ll know better what to do.”
