"I don't know. I'll have to wait till Aunt Sarah goes out or goes away. I hope I shall not forget it before then. I'll sing it over every day and then maybe I won't forget."
The lady looked at her thoughtfully for a minute. "Can you keep a secret?" she asked suddenly.
"Oh, yes. Why, nobody, not even Mary Lee, has an idea about this." She waved her hand to include her music-room retreat.
"Then promise not to tell a soul."
"I promise." Nan's eyes grew eager.
"I am your fairy godmother, and if you will meet me under the sunset tree to-morrow morning at ten o'clock, I will conduct you to a place where you can finish your song undisturbed, for I guarantee Aunt Sarah will not be caught napping within hearing of you and the melodeon."
"Oh, how perfectly delicious," cried Nan, her imagination all afire. "I'd love that. Where is the sunset tree? It is such a lovely name for it."
The lady pointed to a huge oak just across the brook. "It is called that because one can see the sunset so finely from there. Have you never been up to look at the sun go down behind the hills? There is one little notch between the mountains over there and at a certain season of the year the sun drops right down into it."
"I have never seen it," said Nan, regretfully. "I wonder why no one ever told me about it. I think sunset tree is such a lovely name and it is just the spot for a trysting place. It would be a lovely secret, but I never had a real important one from mother before. I shall have to tell her about going up there; not right away, but some day. It always comes out sooner or later and I would rather tell just mother, if you don't mind."
