"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."
