So Helen, watching the business of the stage with eyes from which the tears would _not_ keep back, while those thrilling strains rose and fell in the outcry of remorseful passion, or the wail of hopeless, yet undying love, wondered vaguely why there should be all this sorrow upon earth, springing, apparently, from the purest and most elevated instincts of the human heart. She forgot that a time would come hereafter, perhaps on this side the grave, when the misery that was eating into her own young life must seem no less unreasonable, no less unreal, than that of the harmonious lady yonder, in pearls and white satin, who would take her place at supper in an hour, with spirits and appetite unimpaired by the breaking heart that, flying mellifluously to her lips in this intricate _cavatina_, brought down on her a rainbow shower of bouquets, followed by a thunderstorm of applause. "That _is_ singing!" said Miss Ross, from the back of the box, drawing a long breath of intense enjoyment, the enjoyment of the artist who appreciates as well as admires. "Rose, why didn't I bring a bouquet? I'd throw my head at her if it would take off!" Mrs. Lascelles laughed, and made a sign signifying "Hush!" while Miss Ross whispered over Helen's shoulder--"Isn't it _too_ delightful, dear? In my opinion music's the only thing worth living for!" Helen, who esteemed nothing much worth living for at that moment, responded with modified enthusiasm, and turned languidly to the stage. Just then the box-door opened; and she knew, though he was behind her, and had not spoken a syllable, that it admitted Frank Vanguard! He couldn't keep away! Of course he would not have allowed that any part of this crowded house held for him the slightest attraction. Fidgetting in the stalls, and getting Helen's well-remembered profile within range of his opera-glasses, it was only natural he should tell himself she could never be more to him than a humiliating memory, a cause of gratitude for his narrow escape. It was also natural that he should take his good manners severely to task for negligence, in not having called lately on Mrs. Lascelles, and should scout the notion of being kept out of her box by anybody in the world, man or woman! So, looking paler than usual, and, for once in his life, almost pompous in his embarrassment, he tapped at the door, and found himself stumbling over a delicate little satin-shod foot, belonging to Miss Ross, of whose presence, to do him justice, till he made this ungainly entrance, he had not the slightest suspicion! "It's a good omen!" thought that quaint and speculative young person, while _her_ heart too was beating faster than common. "I shall trip you up at last, sir; and what a fall I'll give you!" But she reflected also that they would probably go down together; and there was something not unpleasant in the apprehension.
