I have always maintained, my dear Currier, that if a man wishes to be considered sane, and has any particular regard for his reputation as a truth-teller, he would better keep silent as to the singular experiences that enter into his life. I have had many such experiences myself; but I have rarely confided them in detail, or otherwise, to those about me, because I know that even the most trustful of my friends would regard them merely as the outcome of an imagination unrestrained by conscience, or of a gradually weakening mind subject to hallucinations. I know them to be true, but until Mr. Edison or some other modern wizard has invented a search-light strong enough to lay bare the secrets of the mind and conscience of man, I cannot prove to others that they are not pure fabrications, or at least the conjurings of a diseased fancy. For instance, no man would believe me if I were to state to him the plain and indisputable fact that one night last month, on my way up to bed shortly after midnight, having been neither smoking nor drinking, I saw confronting me upon the stairs, with the moonlight streaming through the windows back of me, lighting up its face, a figure in which I recognized my very self in every form and feature. I might describe the chill of terror that struck to the very marrow of my bones, and wellnigh forced me to stagger backward down the stairs, as I noticed in the face of this confronting figure every indication of all the bad qualities which I know myself to possess, of every evil instinct which by no easy effort I have repressed heretofore, and realized that that _thing_ was, as far as I knew, entirely independent of my true self, in which I hope at least the moral has made an honest fight against the immoral always. I might describe this chill, I say, as vividly as I felt it at that moment, but it would be of no use to do so, because, however realistic it might prove as a bit of description, no man would believe that the incident really happened; and yet it did happen as truly as I write, and it has happened a dozen times since, and I am certain that it will happen many times again, though I would give all that I possess to be assured that never again should that disquieting creation of mind or matter, whichever it may be, cross my path. The experience has made me afraid almost to be alone, and I have found myself unconsciously and uneasily glancing at my face in mirrors, in the plate-glass of show-windows on the shopping streets of the city, fearful lest I should find some of those evil traits which I have struggled to keep under, and have kept under so far, cropping out there where all the world, all _my_ world, can see and wonder at, having known me always as a man of right doing and right feeling. Many a time in the night the thought has come to me with prostrating force, what if that thing were to be seen and recognized by others, myself and yet not my whole self, my unworthy self unrestrained and
