"Don't," said Grace. "What I don't know won't hurt me."

"Let's all agree that you both look as bad as you can," said Betty crossly, for the strain of a sleepless night was beginning to tell. "It would be a relief to know the worst, anyway."

"Oh, for goodness' sake, Betty, don't you begin to disturb the peace, too," Amy broke in sleepily. "It was bad enough before with Grace and Mollie always at swords' points, but if you begin it, I don't know what I shall do."

Amy's despair was so comical that the girls had to laugh in spite of themselves. As if at a signal, the sun broke through the heavy mist that had risen over night and flooded the room with golden beams. Somehow the world suddenly seemed a better and a happier place to live in, and the girls' spirits rose like mercury.

"Do you suppose Mrs. Irving will really want to go?" Amy asked, as they finished dressing. "She seemed eager enough last night, but she may have changed her mind by this time."

"I don't think so," said Betty. "She is as game as we are for things like that."

"Yes, and she is feeling better now," said gentle little Amy.

The boys called for them bright and early. It seemed that they, also, had spent a rather restless night, and were glad of the sunshine and warmth of the morning.

The party started off in high spirits to find the cave and solve its mysteries. Mrs. Irving was with them, for, as Betty had said, she was a game little person and in for a good time whenever one could be found.

"Suppose we can't find the place?" it was Grace who voiced the thought that had been secretly troubling them all. "Betty just found it by accident yesterday."
