“I know you have,” smiled Billy; “but you were very late to bed last night, and you've got a hard day before you. I insist upon your resting. You will be absolutely undisturbed there, and you must shut the door and not come down-stairs till I send for you. Mr. Johnson isn't due till quarter of eleven, is he?”

“N-no.”

“Then come with me,” directed Billy, leading the way up-stairs. “There, now, don't come down till I call you,” she went on, when they had reached the little room at the end of the hall. “I'm going to leave Aunt Hannah's door open, so you'll have good air—she isn't in there. She's writing letters in my room, Now here's a book, and you may read, but I should prefer you to sleep,” she nodded brightly as she went out and shut the door quietly. Then, like the guilty conspirator she was, she went down-stairs to wait for Arkwright.

It was a fine plan. Arkwright was due at ten o'clock—Billy had specially asked him to come at that hour. He would not know, of course, that Alice Greggory was in the house; but soon after his arrival Billy meant to excuse herself for a moment, slip up-stairs and send Alice Greggory down for a book, a pair of scissors, a shawl for Aunt Hannah—anything would do for a pretext, anything so that the girl might walk into the living-room and find Arkwright waiting for her alone. And then—What happened next was, in Billy's mind, very vague, but very attractive as a nucleus for one's thoughts, nevertheless.

All this was, indeed, a fine plan; but—(If only fine plans would not so often have a “but”!) In Billy's case the “but” had to do with things so apparently unrelated as were Aunt Hannah's clock and a negro's coal wagon. The clock struck eleven at half-past ten, and the wagon dumped itself to destruction directly in front of a trolley car in which sat Mr. M. J. Arkwright, hurrying to keep his appointment with Miss Billy Neilson. It was almost half-past ten when Arkwright finally rang the bell at Hillside. Billy greeted him so eagerly, and at the same time with such evident disappointment at his late arrival, that Arkwright's heart sang with joy.

“But there's a rehearsal at quarter of eleven,” exclaimed Billy, in answer to his hurried explanation of the delay; “and this gives so little time for—for—so little time, you know,” she finished in confusion, casting frantically about in her mind for an excuse to hurry up-stairs and send Alice Greggory down before it should be quite too late.

No wonder that Arkwright, noting the sparkle in her eye, the agitation in her manner, and the embarrassed red in her cheek, took new courage. For so long had this girl held him at the end of a major third or a diminished seventh; for so long had she blithely accepted his every word and act as devotion to music, not herself—for so long had she done all this that he had come to fear that never would she do anything else. No wonder then, that now, in the soft radiance of the strange, new light on her face, his own face glowed ardently, and that he leaned forward with an impetuous rush of eager words.

“But there is time, Miss Billy—if you'd give me leave—to say—”

“I'm afraid I kept you waiting,” interrupted the hurried voice of Alice Greggory from the hall doorway. “I was asleep, I think, when a clock somewhere, striking eleven—Why, Mr.—Arkwright!”

Not until Alice Greggory had nearly crossed the room did she see that the man standing by her hostess was—not the tenor she had expected to find—but an old acquaintance. Then it was that the tremulous “Mr.-Arkwright!” fell from her lips.
