As I look back upon my frame of mind at that moment and consider the impulse which sent me forth from my room at that hour of the night, I realise how overwrought I was. At a distance, in cold blood, it seems an absurd thing to have done; yet, under the same conditions, I should no doubt behave again in much the same way. And even admitting its absurdity, I am not prepared to say, in view of the event, that there was not back of it some instinct worth following. There are forces in nature not yet explained or recognised, and I am still inclined to think that it was one of these which drew me forth upon that midnight errand. In a very fever of impatience, I hurried along the street, under the trees, meeting no one except a patrolman. I heard him stop, as I passed him, and knew that he was looking back after me, but I kept on without pausing, and heard him finally start on again. In a minute more I reached the Lawrence place, and stopped in the shadow of a tree for a look around. The house loomed through the darkness grim and gloomy, with no light showing anywhere. I leaped the fence, assured that I was unseen, and pushed my way forward through the grove toward the path which led to the cottage. Beneath the trees, the darkness was absolute and I could go forward but slowly; yet, starting from the library steps, I found the path without difficulty, and felt my way cautiously along it, until I came to the hedge which marked the limits of the Kingdon place. I examined the house with care, but there was fronting me no lighted window upon which a tragedy could be pictured. Indeed, I saw no vestige of a light and was about to conclude that my midnight pilgrimage had been in vain, when my eye was caught by a faint glimmer near the ground. At first, I was not sure it was a light at all; then I decided that it was a reflection of some sort, or perhaps a phosphorescent glow. But as I stared at it, with eyes contracted, it suddenly took shape in the darkness, and I saw that the light proceeded from a small ventilator set in the foundation of the house. Trembling with excitement, I softly opened the gate and entered the grounds. Here, with nothing between me and the stars, I suddenly found myself in what seemed a veritable blaze of light. I was seized with panic lest I be seen and scurried into the shadow of the house, then dropped beside the ventilator and examined it. It was of the ordinary type--a plate of iron some six or eight inches square, perforated with holes perhaps half an inch in diameter, and set in the foundation about six inches from the ground.
