They parted with the understanding that, when he came next, she should give him his first lesson in reading music. With herself Mary made merry at the idea of teaching the man of genius his letters.

But, when once, through trying to play with her one of his own pieces which she had learned from hearing him play it, he had discovered how imperative it was to keep good time, he set himself to the task with a determination that would have made anything of him that he was only half as fit to become as a musician.

When, however, in a short time, he was able to learn from notes, he grew so delighted with some of the music Mary got for him, entering into every nicety of severest law, and finding therein a better liberty than that of improvisation, that he ceased for long to play anything of his own, and Mary became mortally afraid lest, in developing the performer, she had ruined the composer.

"How can I go playing such loose, skinny things," he would say, "when here are such perfect shapes all ready to my hand!"

But Mary said to herself that, if these were shapes, his were odors.

CHAPTER XLV.
THE SAPPHIRE.

One morning, as Mary sat at her piano, Mewks was shown into the room. He brought the request from his master that she would go to him; he wanted particularly to see her. She did not much like it, neither did she hesitate.

She was shown into the room Mr. Redmain called his study, which communicated by a dressing-room with his bedroom. He was seated, evidently waiting for her.

"Ah, Miss Marston!" he said; "I have a piece of good news for you—so good that I thought I should like to give it you myself."

"You are very kind, sir," Mary answered.
