Just at this moment came a peal of ringing laughter from the garden. It was Lucy's voice; it sounded as if she were standing just on one side of the open casement--and as though she were suddenly stirred to merriment--merriment verging on boisterousness, by the doings or sayings of some other person. I can scarcely say why, but the sound jarred on me inexpressibly. She knew the subject of our conversation, and must have been at least aware of the state of agitation her friend was in: she herself usually so gentle and quiet. I half rose to go to the window, and satisfy my instinctive curiosity as to what had provoked this burst of ill-timed laughter; but Mrs. Clarke threw her whole weight and power upon the hand with which she pressed and kept me down. 'For God's sake!' she said, white and trembling all over, 'sit still; be quiet. Oh! be patient. To-morrow you will know all. Leave us, for we are all sorely afflicted.

I turned away; having my own suspicions, I confess, as to Mistress Clarke's sanity. Conjectures as to the meaning of her hints, and uncomfortable thoughts connected with that strange laughter, filled my mind. I could hardly sleep. I rose early; and long before the hour I had appointed, I was on the path over the common that led to the old farm-house where they lodged. I suppose that Lucy had passed no better a night than I; for there she was also, slowly pacing with her even step, her eyes bent down, her whole look most saintly and pure. She started when I came close to her, and grew paler as I reminded her of my appointment, and spoke with something of the impatience of obstacles that, seeing her once more, had called up afresh in my mind. All strange and terrible hints, and giddy merriment were forgotten. My heart gave forth words of fire, and my tongue uttered them. Her colour went and came, as she listened; but, when I had ended my passionate speeches, she lifted her soft eyes to me, and said:
