When she returned the three sat on the window seat and ate their long-delayed supper. At first Elsie said she wasn’t hungry and couldn’t possibly eat, but Jack laughed her out of that. Soon Rose came up to join them, carrying her ice, and stopping to take dainty tastes as she came.

“This is the nicest situation of all,” she exclaimed, settling down beside Elsie. “And what a view it offers. Why, it’s like being in a box at the theatre. We saw you and Kate, by the way, at ‘The Blue Bird.’ We thought it very grand of you to have a whole box to yourselves.”

Others followed Rose, some of them with plates of ice cream. And Kate noticed that the ices and the ice cream were in every case in a stage of melting. She suspected then that Jack had overheard the conversation about the missing Elsie and had collected this little band, encouraging them to eat slowly. The realization of his tact and consideration wiped out for ever any lurking indignation toward him left over from the morning, when he had squirmed at the idea of her calling Elsie down to play tennis.

A few minutes later, when Miss Frazier came out into the hall with old Mrs. Van Vorst-Smith who was leaving and seemed to require her escort, she saw to her great surprise and relief that the very merriest part of the party was on the stairs. There were eight or nine girls and boys crowded about Kate and Elsie talking eagerly and interrupting themselves with the lightest-hearted laughter. No need to worry any more now because her girls were not on the floor dancing. This was an even better way of getting acquainted. Mrs. Van Vorst-Smith, feeling for an instant that she had lost the full attention of her hostess, followed her gaze upward. Kate was looking down, and their eyes met. Then old Mrs. Van Vorst-Smith did an amazing thing. At least, the few people who observed it were amazed. She made the motion of “good-night” with her lips to Kate, and blew her a kiss.

Both her grandchildren stared round-eyed. “I say,” Jack whispered, “you have certainly charmed my grandmother. What did you ever do to her?”

He looked at Kate, wonderingly respectful, with frankest curiosity.

When Miss Frazier returned from seeing the old lady out of the door, she stood for a minute within hearing of the conversation on the stairs. They were discussing “The Blue Bird” now, but presently it changed to “The King of the Fairies,” a book they all had read, apparently. She smiled inwardly, well pleased. “Katherine over again,” she told herself. But she had to admit, too, that Elsie was doing her share in keeping the subject at a high-water-mark of intelligent conversation. “Kate is certainly having an influence,” she reflected, “an even finer influence than I could have hoped for.” Then she passed on into the drawing-room, trailing her black scarf more regally than ever since she was so honestly proud of both her nieces.

When the last guest had departed Miss Frazier took an arm of each niece and led them toward the stairs. “It was all a great success,” she affirmed. “And it was you girls, yourselves, who made it a success. Kate, you were what a new girl—at least, any new girl worth her salt—ought to be, the belle of the ball. And, Elsie, you did me more than credit. I am, oh, so very proud of both my girls. Old maiden aunt that I am, I felt that I had two lovely daughters. Now I advise you to dash to bed and save all discussion of the party until morning. Breakfast is ordered for half-past nine to-morrow, so that you may sleep.”

“But sha’n’t we help you close up?” Elsie offered. “I heard you tell Isadora to go to bed.”

“No, thank you, my dear. I am going to stay down here awhile, finishing ‘The King of the Fairies.’ I was almost at the last chapter when Mrs. Van Vorst-Smith led the procession of arrivals. It is an enchanting story, just as you said. Now, good-night.”
