The sisters rose and went to a very old-fashioned grand piano, opened it, and Gertrude's fingers swept the wiry jangling chords which sounded quite in keeping with the room; then, subduing the music as much as possible, so that their fresh young voices dominated, rising and falling in a rich harmony that floated through the room, they sang the old, old duet, "Flow on, thou shining river." Every note seemed to have in it the sadness of age, the mournful blending of the bygone when hope was young and disappointment and care had not crushed with a load of misery a heart once fresh as those of the singers. A deep sigh came from the little panel, unheard, though, by the two girls, and the hand appeared once more for the thin white fingers to tap the wood gently in unison with the music, which was inexpressibly sweet, though sad. For how is it that those melodies of the past, even though major, seemed to acquire a mournful tone that is not minor, but has all its sad sweetness? Take what pathetic air you will of a generation or two back, and see if it has not acquired within your knowledge a power of drawing tears that it had not in the days of old. From the simple duet, first one and then the other glided to the old-fashioned ditties popular thirty or forty years before. "Those evening bells," "Waters of Elle," and the like, till, without thinking, Gertrude began "Love not," her sweet young voice sounding intensely pathetic as she went on, gradually gathering inspiration from the words, till in the midst of the sweetest, most appealing strain, she uttered a cry of misery, and threw herself sobbing into her sister's arms. "Oh, Gerty, darling, why did you sing that?" whispered Renee, trying to soothe her, as her own tears fell fast, but for a few minutes in vain, till by a brave effort Gertrude got the better of her hysterical feelings, and, hastily wiping her eyes, glanced towards the panel, where the bowl of water stood upon the bracket, but the opening was closed. The sisters looked piteously at one another, and Renee whispered: "Speak to him. Tell him you did not wish to make him angry." Gertrude glided to the panel, and, stifling a sob, she said softly: "Uncle, dear uncle, do not be cross with me--I am very sorry. I was so miserable." There was no reply--no sound to indicate that the words had been heard; and after waiting for about a quarter of an hour the two girls crossed to the door, went slowly out, and found that they had had an audience in the shape of Valentine Vidler and his wife, who had been seated upon the stairs. "Thank you, my dears," said Salome, nodding and smiling. "We like to hear you sing. You have made a very long stay to-day, and his lunch is quite ready." The sisters were too heartsore to trust themselves to say much, and Vidler opened the door for them, admitting as little light as he could by closing it directly and going to assist his wife.
