But Esther was not paying her any special attention. Quietly she shook her head. "No, Polly, I am not going home. I am so sorry, for I wanted to dreadfully. But my music lessons are so expensive that father does not feel he can afford to let me come. I haven't yet had the courage to write and break the news to the Princess. She is fond of me, don't you think so, Polly? She will be sorry that I can't be with her for the holidays? Of course I know she does not care for me as she does for you. I shall never expect that. But it does mean so much to me to feel sure of her affection." Polly frowned in a slightly puzzled fashion. Esther's adoration even of her beloved Betty seemed a little unnatural. Why should one girl care so much about the attitude of another one? She loved Betty herself, of course, and Betty loved her. Yet she doubted very much if either one worried over the emotions of the other. "Oh, yes, Esther," Polly returned a trifle impatiently. "Of course Betty is devoted to you. Why shouldn't she be? Really, I do think you would let her almost trample upon you if she liked. Only Betty never would like to hurt any one, thank heaven! But I am glad to hear you are not going home for the Christmas holidays, because I am not going either." There was nothing so remarkable in this statement that it should make Polly turn white and then red again. But fortunately the three Camp Fire candles, "Work, Health and Love," were now flickering so that the elder girl could not get a clear vision of the other's face. But instead of appearing pleased over this news Esther seemed disappointed. "I am so sorry, for Betty's sake," she returned. "She wouldn't mind my not being with her so much if she only might have you." Polly shrugged her thin shoulders in a fashion she had when vexed. "O Esther, I think you might have been polite enough to say that you would be glad to have me in town if you were to be here--particularly when I came to ask you if I might spend the holidays with you." "Spend the holidays with me?" Esther repeated in rather a stupid fashion. Naturally she was puzzled as to just why a girl in Polly's position should elect to spend her Christmas vacation in a cheap New York boarding house with another girl for whom she had no special sentiment. "Why in the world do you want to remain in the city with me?" she asked again, too honest to pretend that pleasure was her first sentiment until she got a more definite understanding of the situation. But Polly was now making no effort to devote her attention either to eating or drinking. Instead she had rested both elbows on the table and was looking at her companion with the half-pleading, half-commanding expression that both Mollie and Betty knew so well. "Promise not to say anything until I have finished?" she began coaxingly. "For you see it is to explain why I want to stay with you that made me write to ask you to make this engagement with me for this afternoon."
