"After two terms with him, I know exactly what he wants," reflected Rosemary. "I could teach someone else, though I could not do it myself. There are all my books of exercises and studies packed away at home; I'd made up my mind never to look at them again. Oh, dear! It will be like opening a wound to get them out. Shall I, or shall I not? The girl seems contented enough as she is."

It takes some qualifications for sainthood to hold open for another the door of a paradise you may not enter yourself. As Rosemary's mind see-sawed up and down, her eyes fell on a quotation printed on a calendar which hung in her room.

"Four things come not back to man or woman—the sped arrow, the spoken word, the past life, and the neglected opportunity."

"It is an opportunity," she mused; "an opportunity of helping such as probably I shall never find again in the whole of my life. Rosemary Doris Forrester, you've got to buck up and not be an envious beast. You're going to unpack that music, and teach that girl all you know. I say so, the real I—not the horrid, mean, jealous, selfish, contemptible part of me. Here goes! I'll write and propose it, and send the letter up at once by Lorraine, so as to burn my boats. I hope to goodness Claudia will have the sense to snatch at such a good offer. I shan't tell anybody a word about it beforehand."

Lorraine, who always went willingly on any errand to Windy Howe, handed over her sister's impulsive letter, quite unwitting of its contents. Claudia read it, flushed, and caught her breath with a sharp little cry. She turned to her friend with eyes like two stars.

"Do you know what Rosemary proposes?" she asked.

"No."

"Why, she actually offers to teach me to sing! And oh, Lorraine! She hints that, if I try hard, she would write to Signor Arezzo and ask him to hear me, and perhaps he would be able to give me a scholarship for the college, and I could go and study."

It was Lorraine's turn to assimilate the surprise.

"Good old Rosemary! She's a trump card! But I thought you didn't care about winning scholarships, Claudia. I believe you missed sending in that application on purpose."
