WAS it a specter? For days I could not answer this question. I am no believer in spiritual manifestations, yet-But let me tell my story. I was lodging with my wife on the first floor of a house in Twenty-seventh street. I had taken the apartments for three months, and we had already lived in them two and found them sufficiently comfortable. The back room we used as a bedroom, and while it communicated with the hall, we invariably made use of the front parlor-door to go in and out of. Two great leaves of old mahogany connected the two rooms, and as we received but few friends, these doors usually stood half open.
