There I lay, piling conjecture and supposition high upon each other; but not at all could I conjecture how it was that the face which I had last seen in my own home, under the gray bonnet of a sister of Martha, should flash upon my vision in this far-away spot, and from the surface of a woodland stream.

It was growing dusky, when I heard a loud whistle, and my name was called. I whistled in return, and in a few moments Walkirk came running to me.

"I was beginning to get frightened," he said. "I have been looking everywhere for you. We have had supper, and the party is breaking up. There is no moon to-night, and the people must start early for their homes."

"Let them all get away," I replied; "and when they are entirely out of sight and hearing let me know, and I'll go in to supper."

"I am afraid," said Walkirk, hesitating, "that they will not like that. You know these country people are very particular about leave-taking, and all that sort of thing."

"I can't help it," I answered. "I don't feel at all like seeing people at present. You can go and bid them good-by in my name."

"As an under-study?" said he, smiling. "Well, if I can tell them you are out of condition and not feeling like yourself, that will make it all right, and will also explain why you kept yourself away all the afternoon." With this he left me, promising to return when the guests had departed. It was a long time before he came back, and it was then really dark.

"Your supper is awaiting you," he announced, "and I am afraid that Mrs. Jabe is contemplating a hot footbath and some sort of herb tea; and we ought to turn in pretty early to-night, for Captain Jabe has announced that he will sail between four and five o'clock in the morning."

"Walkirk," said I, sitting up in the hammock, "I have no intention of sailing to-morrow. I prefer to stay here for a time; I don't know for how long."

"Stay here!" exclaimed Walkirk. "What on earth can you do here? What possible attraction can this place have?"
