"We will do all we can," promised Mollie.

They entered the old mansion. Truly it had been a magnificent place in its day, and even now the hand of decay had touched it but lightly. With a few repairs, some decorating, a cutting down of the trees that were too thick about the place, it could be made into a most cheerful sanitarium.

"And it's so big!" cried Grace, as she wandered about the spacious rooms. But she had hold of Amy's arm, it might be noticed, and both girls kept rather near to Mr. Blackford. He had come back unsuccessful in his search for his sister.

"Yes, it must have been fine here when the place was new," agreed Mollie. "Well, let's go at this search systematically."

"That is the only way," spoke Mr. Blackford. "We might start in at the top and work downward."

They did this, ascending by means of the grand staircase to the second floor, and thence to the third and fourth. The latter contained but few rooms, mostly for storage, it seemed, and it was soon evident that no ghost—of the human kind at least—had been at work here. The dust and grime of years had accumulated in the apartments.

The third floor offered no solution. This was rather larger in extent, and contained many guest-rooms. Some showed evidence of having been beautifully decorated, being paneled in tapestry that now hung in shabby strips—a relic of former beauty.

It was not until the second floor was reached that anything like a promising clue was found. Meanwhile many queer nooks and corners had been explored. Mr. Kenyon had evidently built the house after his own eccentric ideas, for it contained strange rooms, connecting with one another by little, unexpected passages, short flights of stairs, and many winding ways. Some of the rooms might well have been secret ones, so strangely were they tucked away.

But in two apartments on the second floor—two rooms that had evidently been choice guest chambers—the searchers came upon signs which indicated clearly that some one had been in them recently. There was less dust, and in one corner was a pile of bags and rags that seemed to indicate a bed. On the hearth—there were big fireplaces in each room—were ashes that had been hot not many days gone by.

"Tramps!" exclaimed Mr. Blackford. "To my way of thinking tramps have been sleeping here."
