The picture was very vivid for a while, but gradually gave way to a more horrible conception; that of utter, absolute solitude in infinite, sightless, soundless space. There seemed to be a void, and nothing more, and I felt a childish fear which prompted me to draw from my hip pocket the revolver I always carried after dark since the night I was held up in East Providence. Then, from the farthermost regions of remoteness, the sound softly glided into existence. It was infinitely faint, subtly vibrant, and unmistakably musical, but held a quality of surpassing wildness which made its impact feel like a delicate torture of my whole body. I felt sensations like those one feels when accidentally scratching ground glass. Simultaneously there developed something like a cold draft, which apparently swept past me from the direction of the distant sound. As I waited breathlessly I perceived that both sound and wind were increasing; the effect being to give me an odd notion of myself as tied to a pair of rails in the path of a gigantic approaching locomotive.
