"And," Jean went on still intent upon her tale, "there was a great big Christmas tree at the last and the king and the king's brother—he was the prince who loved the princess—and a lot of the court were all there, then afterward the prince found the princess and she had served her time as a servant so she could free her brother, so she did, and oh, it was fine. There were so many lovely things. There was a fairy who appeared and disappeared like magic, and—oh, yes, I forgot, there was such a funny dance——"

"I—don't care," said Jack in a broken voice and rushing from the room. After all, her sacrifice had not seemed to mean much. Every one had been entertained and had not missed her greatly. Even Jean, her own twin, had not said she was sorry that her little sister was not there, but seemed, on the contrary, rather to triumph over her. They had not said much about Bertha, and—well the tears began to run down her cheeks as she stood alone in the dark by the window of the room where she and Jean slept.

Presently the door opened softly and some one came in. "Is that you here in the dark, Jacksie?" It was Nan who spoke. "I am so sorry you missed the play. I couldn't half enjoy it for thinking about you. But, honey, you did the loveliest thing for little Bertha, and you are a real little Princess Herzlieb yourself, because poor Bertha is shut out from everything, from all the lovely things and the comforts you have and you broke the spell by making a sacrifice, just as the Princess Herzlieb did in the play."

"Oh, Nan, did I?"

"Of course, for you gave her such a wonderful pleasure. I wish you could have seen her great eyes and her happy little face. She will remember this afternoon all her life, I am sure. Aunt Helen and I talked to her as we were coming out, and we are going to find out more about her. Her mother is dead and she doesn't know where her father is. She lives with an aunt who has a great many children and I think must be very poor."

"Maybe she is the switch woman."

"Very likely. At any rate we shall find out soon, and we are going to see about a jolly good Christmas for them all. Do you remember last year and little Christine? You did that, too, little Princess Heartlove. Your old Nan understands, doesn't she? I know you can't help being half sorry, but when you see how it will all turn out for Bertha, you will be glad you served without speaking."

"You are so nice, Nan," said Jack, giving her sister a close hug. "You always do understand, and you never think I am half as bad as other people think."

"You are anything but bad. Sometimes you do thoughtless things, but you don't really mean to be naughty."
