Doris thought she had never tasted anything more delightful than that impromptu little repast. And when it was over, she asked Miss Camilla a question, for she had been chatting with her all along, in decided contrast to the rather embarrassed silence of Sally.

“What is that beautiful little vase you have there, Miss Roundtree, may I ask? I’ve been admiring it a lot.” A wonderful light shone suddenly in Miss Camilla’s eyes. Here, it was plain, was her hobby.

“That’s a Louis XV Sèvres,” she explained, patting it lovingly. “It is marvelous, isn’t it, and all I have left of a very pretty collection. It was my passion once, this pottery, and I had the means to indulge it. But they are all gone now, all but this one. I shall never part with this.” The light died out of her eyes as she placed the precious piece back on the mantel.

“Good-bye. Come again!” she called after them, as they took their departure. “I always enjoy talking to you children.”

When they had retraced their way to the boat and pushed off and were making all speed for the hotel, Sally suddenly turned to Doris and demanded:

“Why in the world are you so interested in Miss Camilla? I’ve known her all my life, and I never talked so much to her in all that time as you did this morning.”

“Well, to begin with,” replied Doris, shipping her oars and facing her friend for a moment, “I think she’s a lovely and interesting person. But there’s something else besides.” She stopped abruptly, and Sally, filled with curiosity, demanded impatiently,

“Well?”

Doris’s reply almost caused her to lose her oars in her astonishment.

I think she knows all about that cave!
