"I think you did," he laughed. "I happened to put my head out of a ventilating hole just as you looked. I pulled it in again, soon enough, though. I hope I didn't scare you."

"Not very much," Flossie said. "I was sure I saw you, but nobody else would believe me."

Snap soon made friends with the new boy. It was Will, hiding behind the closet wall, that had made the dog act as though a rat were there.

I must bring my story to a close, now that the mystery is explained. And, really, there is little else to tell. Will had, in the little bundle of things he had brought away from Mr. Hardee's with him, the address of a man he thought knew where the miner uncle was. Mr. Bobbsey wrote several letters, and, in due time, word came back that Will's uncle was well off now, and would look after him. His name was Mr. Jackson. He had lost track of Will for some years and had just begun a search for him, when Mr. Bobbsey's letter came. Enough money was sent on to enable Will to make the trip out west, where he would be well cared for. He could not thank the Bobbsey family enough for what they had done for him.

Mr. Hardee heard where his runaway boy had been found, and tried to get him back, but Mr. Bobbsey would not permit this. So Will's life began to be a pleasant one. The time he had spent on the houseboat, after coming from his hiding place, was the happiest he had ever known.

"Well, what shall we do now?" asked Bert one day, after Will had gone. "It seems queer not to have to be on the lookout for a mystery or something like that."

"Doesn't it," agreed Harry.

"And so that was your secret?" asked Nan.

"Yes, that was it," her brother answered. "But I wish we had something to do now."

"Whatever you do, you want to do in the next two weeks," said Mr.
Bobbsey, coming up on deck.
