"When I went back into the car, that girl passed me on the way to her stateroom, and I concluded that she was the only woman on board, and her friends had taken the stateroom for her, so that she needn't feel strange. I usually go to bed in a sleeper as I do in my own house, but that night I somehow couldn't. I got to thinking of accidents, and I thought how disagreeable it would be to turn out into the snow in my nighty. I ended by turning in with my clothes on, all except my coat; and, in spite of the red-hot stoves, I wasn't any too warm. I had a berth in the middle of the car, and just as I was parting my curtains to lie down, old Melford came to take the lower berth opposite. It made me laugh a little, and I was glad of the relief. 'Why, hello, Melford,' said I. 'This is like the old Holworthy times.' 'Yes, isn't it?' said he, and then I asked something that I had kept myself from asking all through our talk in the smoking-room, because I knew he was rather sensitive about it, or used to be. 'Do you ever have that regulation nightmare of yours nowadays, Melford? He gave a laugh, and said: 'I haven't had it, I suppose, once in ten years. What made you think of it?' I said: 'Oh, I don't know. It just came into my mind. Well, good-night, old fellow. I hope you'll rest well,' and suddenly I began to feel light-hearted again, and I went to sleep as gayly as ever I did in my life." The stranger paused again, and Wanhope said: "Those swift transitions of mood are very interesting. Of course they occur in that remote region of the mind where all incidents and sensations are of one quality, and things of the most opposite character unite in a common origin. No one that I remember has attempted to trace such effects to their causes, and then back again from their causes, which would be much more important." "Yes, I dare say," Minver put in. "But if they all amount to the same thing in the end, what difference would it make?" "It would perhaps establish the identity of good and evil," Wanhope suggested. "Oh, the sinners are convinced of that already," Minver said, while Rulledge glanced quickly from one to the other. The stranger looked rather dazed, and Rulledge said: "Well, I don't suppose that was the conclusion of the whole matter?"
