"Oh, no, he can't," said Flossie.

"Why?" asked her brother.

"'Cause he's never been in our tent-camp. He doesn't know where it is.

But maybe you know, Freddie."

"Yes, I know the way--if--if we can get out of this cave," and he looked at the gypsies. They were talking among themselves. One of them walked toward Snap and held out his hand toward a broken rope around the dog's neck. But the animal growled in such a fierce way that the gypsy drew back in fear.

Then there was more talk among the dark-faced men about the children and the dog. The men seemed to be worried. Snap barked and ran a little way ahead, as though to lead the way out of the cave. Again a man tried to catch him, but the dog's savage growl made him draw back.

"I guess Snap wants us to come with him," said Flossie. "Let's go, Freddie."

"All right--come on;" and Freddie, taking Flossie's hand, started out of the cave. They were afraid, the children were, that the gypsies might stop them, but the man who had had the lantern said:

"Come on. I'll show you two the way out and you can go to your camp. No use keeping you, now that your dog is loose. He'd make trouble for us.

Hurry up, you fellows, get things out of the way!" he called to the other gypsies, and they began taking things off the table as though they were going to leave.

But Flossie and Freddie did not care about that. All they knew was that they had found Snap, and that they were going home with him to Twin Camp. And Snap was as glad as were they.

"There you are!" said the gypsy in rather a growling voice, as he led the children to where a big patch of sunlight shone into the cave. "I guess you can find your way home from here."

Flossie and Freddie ran on, Snap going ahead, and, to the surprise of the twins they found themselves at the mouth of the cave--the same place where they had taken shelter from the rain the day they were in the drifting boat.

"Why, look here!" cried Freddie. "Isn't this funny, Flossie? We've come out of the same cave we were in before. How did we get in?"

"I don't know," answered the little girl, "'cept maybe it's a fairy cave an' changes."

But it was not that kind at all. The children had only fallen down a hole at one end of the cave, and when the gypsy man led them through they came out at the other end, where they had first gone in. Snap barked and ran down to the edge of the lake to get a drink of water.

"He's glad to come out," said Flossie.

"Awful glad," agreed Freddie. "So'm I."

"Me, too," added the little girl. "I wonder how he got in there?"

"I guess the gypsies took him," said Freddie. "They liked him 'cause he is such a good dog. I'm so glad we've got him back. Now if we could get Snoop back we'd be all right, wouldn't we, Snap?" and he put his arms around the dog's s.h.a.ggy neck, while Flossie patted his back.

Happy because they had found their dog, and not worrying at all about having been so nearly kept prisoners by the gypsies in the cave, the two little Bobbsey twins hurried away from the cavern. They were anxious to get back to camp to tell the others how they had found Snap. And the dog seemed just as anxious to get away from the cave as were the little boy and girl.

Every once in a while Freddie would turn and look back, and when his sister asked him why he did this he told her he was looking to see if he could see the black cat.

"She ought to be easier to find than Snap," he said, "'cause she was with us here on Blueberry Island, and Snap must have been taken by the gypsies in Lakeport." Afterward they found that this was so.

As the children, with their dog, walked along through the woods, keeping close to the lake sh.o.r.e, as they knew that path led to their camp, Flossie and Freddie heard a shout among the trees.

"There's Nan!" Freddie said.

"Yes, and Bert," added his sister. "I guess they're looking for us."

They were sure of this a little later, for they heard the cry:

"Flossie! Freddie! Where are you?"

"Here we are!" they answered, and then sounded a noise of some one coming toward them. The next moment Nan and Bert came into view. Both stopped in surprise at the sight of the dog.

"Where'd you get him?" asked Nan.

"Is he really Snap?" cried Bert.

"Yep! He really is," answered Freddie. "We found him!"

"In a cave," added Flossie.

"In a cave?"

"And there were gypsies there," went on the little girl.

"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."

But when Mr. Bobbsey got to the cave with the officers the gypsies were not there. They must have known that when the children went out they would tell what had happened and that the police would come. So there was nothing for the police to do. The gypsies had run away. They went to the mainland in boats, some of the blueberry pickers said who had seen them.

"And now that the island is free from the gypsies we'll have lots more fun," said Mrs. Bobbsey. "The thought of them made me nervous."

"Hark!" suddenly exclaimed Nan. She, as well as all the other members of the Bobbsey family, had followed the police to the cave, even Flossie and Freddie going along, riding to the place in the goat wagon drawn by Whisker.

"Hark to what?" asked Bert.

"I thought I heard a noise," said the little girl. "Yes, there it goes again, a sort of squeaky noise."

"It's a--it's a cat!" cried Flossie. "Oh, if it should be----"
