And Lolla, without further hesitation, sprang into the branches of the tree and began to climb.

As she did so the mysterious voice sounded again.

"You cannot see me, yet," it said. "You can only hear me. See, my voice is in your ears, but you cannot see as much as my little finger. Beware; go before you do see me. For when you do, you will regret it; regret it as long as you live!"

When Lolla, a moment later, reached firm ground again, she was trembling, and Bessie saw that her courage was beginning to fail. She looked about her nervously, as Peter was doing. And suddenly the voice spoke again, but this time it shouted, and it was in a stronger, more vigorous tone, and one of great anger.

"Must I show myself! Must I punish you?" it said, furiously. "Fear me; you will do well! Go—GO!"

With a yell of terror Peter turned suddenly, and ran through the thick bushes toward the trail, crying out as he went, and stumbling.

"Come; it is the devil! I saw his horns and his tail then," he screamed. "Come, Lolla, this is an accursed place. I told John it was wrong to try to do this; that he would get into trouble."

"He is wise; he is safe!" said the mysterious voice. "Go too, Lolla; I am growing impatient. Go, if you want to see John, your lover, and the brothers that you love, again. The time is growing short. I come; I come; and when I come—"

And then at last Lolla's nerves, too, gave way, and she followed Peter, screaming, as he had done, while she ran. Bessie, as astonished and almost as frightened as the two gypsies had been, turned then to see how Dolly was bearing this extraordinary affair, to see her chum rolling about on the ground, with tears in her eyes.

"Oh, that was funny!" Dolly exclaimed. "They were easy, after all, Bessie."
