"One night, some weeks ago--I can, if necessary, make myself certain of the date,--I was--no uncommon thing with me--unable to sleep. Sometimes, when such is my case, I lie as still and happy as any bird under the wing of its mother; at other times I must get up and go out, for I take longings for air almost as a drunkard for wine, and that night nothing would serve my poor prisoned soul but more air through the bars of its lungs. I rose, dressed, and went out. "It was a still, warm night, no moon, but plenty of star-light, the wind blowing as now, gentle and sweet and cool--just the wind my lungs sighed for. I got into the open park, avoiding the trees, and wandered on and on, without thinking where I was going. The turf was soft under my feet, the dusk soft to my eyes, and the wind to my soul; I had breath and room and leisure and silence and loneliness, and everything to make me more than usually happy; and so I wandered on and on, neither caring nor looking whither I went: so long as the stars remained unclouded, I could find my way back when I pleased. "I had been out perhaps an hour, when through the soft air came a cry, apparently from far off. There was something in the tone that seemed to me unusually frightful. The bare sound made me shudder before I had time to say to myself it was a cry. I turned my face in the direction of it, so far as I could judge, and went on. I cannot run, for, if I attempt it, I am in a moment unable even to walk--from palpitation and choking. "I had not gone very far before I found myself approaching the hollow where stands the old house of Glaston, uninhabited for twenty years. Was it possible, I thought, that the cry came from the house, and had therefore sounded farther off than it was? I stood and listened for a moment, but all seemed still as the grave. I must go in, and see whether anyone was there in want of help. You may well smile at the idea of my helping anyone, for what could I do if it came to a struggle?" "On the contrary," interrupted Wingfold, "I was smiling with admiration of your pluck." "At least," resumed Polwarth, "I have this advantage over some, that I cannot be fooled with the fancy that this poor miserable body of mine is worth thinking of beside the smallest suspicion of duty. What is it but a cracked jug? So down the slope I went, got into the garden, and made my way through the tangled bushes to the house. I knew the place perfectly, for I had often wandered all over it, sometimes spending hours there.
