"Like Tommy Todd's father," added Freddie.

"Yep. Just like him," said Flossie, "only make-believe, of course."

"And I'll be captain of the ship, and you can be a sailor," went on Freddie. "It'll be lots of fun!"

Bert and Nan had gone riding in the goat wagon to the other end of the island, Mr. Bobbsey was at his office and Mrs. Bobbsey, with Dinah, was working about Twin Camp, so there was no one to watch Flossie and Freddie. Mrs. Bobbsey supposed they were playing safely at the lake shore, and, as a matter of fact, they were on shore, though in the boat.

"I wonder whose it is?" said Freddie, when they had made a make-believe voyage safely to New York, after having been shipwrecked at Philadelphia—a place the little twins remembered, as one of their aunts lived in that city.

"Maybe it's a gypsy boat," said Freddie.

"Or else it's the one the blueberry boy had," added his sister.

"Oh, yes, maybe it is his!" cried Freddie. "And if it is, didn't we better ought to take it to him?"

"How?" asked Flossie.

"Why, we can push it along the shore with sticks, 'cause there's no oars in it, and when we see him picking blueberries we can holler to him to come an' get his boat."
