When she awoke there were still in her ears the sounds which had mingled in her dream. They were the notes of a deep, ringing, bass voice rising from the glen beneath the castle walls--something between humming and singing--listlessly unequal and intermittent, like the melody of a man whiling away the hours over his work. While she was wondering at this unwonted minstrelsy, there came a silence, and--could she believe her ears?--it certainly was Una's clear low contralto--softly singing a bar or two from the window. Then once more silence--and then again the strange manly voice, faintly chaunting from the leafy abyss. With a strange wild feeling of suspicion and terror, Alice glided to the window. The moon who sees so many things, and keeps all secrets, with her cold impenetrable smile, was high in the sky. But Alice saw the red flicker of a candle from Una's window, and, she thought, the shadow of her head against the deep side wall of its recess. Then this was gone, and there were no more sights or sounds that night. As they sate at breakfast, the small birds were singing merrily from among the sun-tipped foliage. "I love this music," said Alice, unusually pale and sad; "it comes with the pleasant light of morning. I remember, Una, when you used to sing, like those gay birds, in the fresh beams of the morning; that was in the old time, when Una kept no secret from poor Alice." "And Una knows what her sage Alice means; but there are other birds, silent all day long, and, they say, the sweetest too, that love to sing by _night_ alone." So things went on--the elder girl pained and melancholy--the younger silent, changed, and unaccountable. A little while after this, very late one night, on awaking, Alice heard a conversation being carried on in her sister's room. There seemed to be no disguise about it. She could not distinguish the words, indeed, the walls being some six feet thick, and two great oak doors intercepting. But Una's clear voice, and the deep bell-like tones of the unknown, made up the dialogue. Alice sprung from her bed, threw her clothes about her, and tried to enter her sister's room; but the inner door was bolted. The voices ceased to speak as she knocked, and Una opened it, and stood before her in her nightdress, candle in hand. "Una--Una, darling, as you hope for peace, tell me who is here?" cried frightened Alice, with her trembling arms about her neck. Una drew back, with her large innocent blue eyes fixed full upon her. "Come in, Alice," she said, coldly. And in came Alice, with a fearful glance around. There was no hiding place there; a chair, a table, a little bedstead, and two or three pegs in the wall to hang clothes on; a narrow window, with two iron bars across; no hearth or chimney--nothing but bare walls. Alice looked round in amazement, and her eyes glanced with painful inquiry into those of her sister. Una smiled one of her peculiar sidelong smiles, and said----
