With the assistance of loving arms, Joy returned to the school and was soon made comfortable in her padded blue silk kimono. Muriel and Gladys brought wood and made a fire on the hearth, while Catherine went kitchenward to fill the copper teakettle with boiling water.

The next day Joy felt as well as she had before, but the girls were unanimous in declaring that she must not play tennis again until spring. Then it was that Joy made a resolution.

CHAPTER XXX.
JOY’S SECRET.

When Joy realized that she would be unable to play in the tournament, which was the formal closing of the tennis season at High Cliffs, she resolved to teach Muriel the trick which her brother had taught her which would send a ball over the net with a smash and kill it before it bounced. The island girl knew the rules of the game, it would seem, and how light she was on her feet and how swift! If she could master that trick in one week, there still might be hope of winning. Muriel was sitting at her desk studying spelling early the next morning when there came a tap on her door. She thought it was the maid of that corridor and called, “Come in.” But when she saw the blue and gold apparition standing in the open doorway she sprang to her feet and held out both hands. “Oh, Joy!” she exclaimed. “It is good of you to come to see me. Do you think you’re strong enough to be walkin’ that far?”

The visitor sank down in the big, comfortably upholstered wicker chair near the hearth, where a bed of coals glowed. “I feel all right this morning,” she said, “but after yesterday’s experience I am convinced that I am not strong enough as yet to play in the tournament; and, Muriel, if you will promise not to share the knowledge without my permission, I will teach you the trick that my brother taught me.”

Muriel’s hazel eyes were wide. “But, Joy,” she ejaculated, “why is it me you would be teachin’ when Faith, Catherine and Gladys all play so much better?”

Joy smiled as she replied: “I have two excellent reasons. One is that the other girls are busy with their classes nearly all of each day, while you and I are not. As yet I have not started the regular work. And so you and I could go down to the court at an hour when it would be unoccupied. My other reason is that you are the only one on our side who can run as does our rival, Marianne Carnot.”

Muriel flushed with pleasure. “I’d be that pleased if I could help win the game,” she said. “I’ll gladly try, though I’m not expectin’ to be able to learn the trick.”

“Try is all that any of us can do in this world, it would seem,” Joy said as she arose. “I see that you are studying, and I, too, must get at my French. Madame Van de Heuton is helping me keep up with the class, as Mother plans a visit to the continent next summer if I am strong enough.” Joy hesitated, then continued: “Muriel, would you like to study French with me? The review from the very beginning would do me just worlds of good.” There were sudden tears in the eyes of the island girl. “How kind you all are to be helpin’ me,” she said, adding: “If you think I’ll be needin’ the French, I’ll try.”

“Indeed you will need it, some time.” Then Joy suggested that they go to the court at two, when every other pupil would be occupied indoors. Muriel said that she would. At the door Joy turned, and lifting a finger, slender as a fairy-wand, she whispered, “Mums the word! Don’t even tell Faith, will you?”
