The circumstances I am about to relate to you have truth to recommend them. They happened to myself, and my recollection of them is as vivid as if they had taken place only yesterday. Twenty years, however, have gone by since that night. During those twenty years I have told the story to but one other person. I tell it now with a reluctance which I find it difficult to overcome. All I entreat, meanwhile, is that you will abstain from forcing your own conclusions upon me. I want nothing explained away. I desire no arguments. My mind on this subject is quite made up, and, having the testimony of my own senses to rely upon, I prefer to abide by it.
