"An' they wanted to keep us," said Freddie.

"But they didn't," added Flossie.

"No. But Snap was there."

"And he growled at the gypsy man."

"And he came away with us."

"Snap was awful glad to see us, Nan."

"And here we are now," said Freddie, putting an end to this duet.

"Oh, dear!" exclaimed Nan. "This is dreadful! Gypsies on this island, and they almost kidnapped you! You must tell daddy right away. We've been looking everywhere for you. We thought you were lost again. And you're all dirty and sandy!" she cried.

"That's where we fell down a hole into the cave," said Freddie, and he told Nan and Bert what had happened. Mr. Bobbsey was much surprised when the twins came home with the long-missing Snap. So was Mrs. Bobbsey, as well as Sam and Dinah.

"Gypsies here, are there?" exclaimed Mr. Bobbsey. "Well, I'll have to see about that. We don't want them hiding in a cave and stealing our things. I guess I'll get some police officers and pay the tribe a visit."
