So the five set off for the lonely cabin.

"I can't understand how the dog came to be there, though," mused Russ, as they walked on through the woods. "That fellow wasn't at the cabin the last time we looked."

"But that was several days ago," Paul reminded him. "He may have been staying there ever since, thinking we had given up going there. That's very likely it."

And this proved to be the case. The man had apparently moved back into the cabin. The room was arranged about as it had been the day the girls took shelter in the place, but there was this change—that a fine collie dog was chained near the big fireplace.

And if ever a dog was glad to see anyone it was that same collie. He jumped about, barking joyfully, but was held back by a strong chain, fastened to his collar.

"Poor fellow!" exclaimed Sandy kindly, and the dog wagged his tail in friendly greeting.

"Oh, I wish we could keep him!" exclaimed Alice, who loved animals.

"I guess we'll have to—until that feller gits out of jail," spoke the young farmer. "They won't allow no animals in the lockup. We'll take him to the farm."

The dog made friends at once, and seemed particularly fond of Alice. She was patting him, when she happened to turn his collar around. A brass plate came into view and as the girl read something on it she uttered a cry of surprise.

"Look!" she exclaimed. "This is the lost dog!"
