It was night, but not late, not more than ten o’clock, the household still astir. Everything was quiet,--not the solemnity of midnight silence, in which there is always something of mystery, but the soft-breathing quiet of the evening, full of the faint habitual sounds of a human dwelling, a consciousness of life about. And I was very busy with my figures, interested, feeling no room in my mind for any other thought. The singular experience which had startled me so much had passed over very quickly, and there had been no return. I had ceased to think of it; indeed, I had never thought of it save for the moment, setting it down after it was over to a physical cause without much difficulty. At this time I was far too busy to have thoughts to spare for anything, or room for imagination; and when suddenly in a moment, without any warning, the first symptom returned, I started with it into determined resistance, resolute not to be fooled by any mock influence which could resolve itself into the action of nerves or ganglions. The first symptom; as before, was that my heart sprang up with a bound, as if a cannon had been fired at my ear. My whole being responded with a start. The pen fell out of my fingers, the figures went out of my head as if all faculty had departed; and yet I was conscious for a time at least of keeping my self-control. I was like the rider of a frightened horse, rendered almost wild by something which in the mystery of its voiceless being it has seen, something on the road which it will not pass, but wildly plunging, resisting every persuasion, turns from, with ever-increasing passion. The rider himself after a time becomes infected with this inexplainable desperation of terror, and I suppose I must have done so; but for a time I kept the upper hand. I would not allow myself to spring up as I wished, as my impulse was, but sat there doggedly, clinging to my books, to my table, fixing myself on I did not mind what, to resist the flood of sensation, of emotion, which was sweeping through me, carrying me away. I tried to continue my calculations. I tried to stir myself up with recollections of the miserable sights I had seen, the poverty, the helplessness. I tried to work myself into indignation; but all through these efforts I felt the contagion growing upon me, my mind falling into sympathy with all those straining faculties of the body, startled, excited, driven wild by something, I knew not what. It was not fear. I was like a ship at sea straining and plunging against wind and tide, but I was not afraid. I am obliged to use these metaphors, otherwise I could give no explanation of my condition, seized upon against my will, and torn from all those moorings of reason to which I clung with desperation, as long as I had the strength.
