I have three or four curious incidents to tell about. They seem to come under the head of what I named “Mental Telegraphy” in a paper written seventeen years ago, and published long afterwards.--[The paper entitled “Mental Telegraphy,” which originally appeared in Harper's Magazine for December, 1893, is included in the volume entitled The American Claimant and Other Stories and Sketches.] Several years ago I made a campaign on the platform with Mr. George W. Cable. In Montreal we were honored with a reception. It began at two in the afternoon in a long drawing-room in the Windsor Hotel. Mr. Cable and I stood at one end of this room, and the ladies and gentlemen entered it at the other end, crossed it at that end, then came up the long left-hand side, shook hands with us, said a word or two, and passed on, in the usual way. My sight is of the telescopic sort, and I presently recognized a familiar face among the throng of strangers drifting in at the distant door, and I said to myself, with surprise and high gratification, “That is Mrs. R.; I had forgotten that she was a Canadian.” She had been a great friend of mine in Carson City, Nevada, in the early days. I had not seen her or heard of her for twenty years; I had not been thinking about her; there was nothing to suggest her to me, nothing to bring her to my mind; in fact, to me she had long ago ceased to exist, and had disappeared from my consciousness. But I knew her instantly; and I saw her so clearly that I was able to note some of the particulars of her dress, and did note them, and they remained in my mind. I was impatient for her to come. In the midst of the hand-shakings I snatched glimpses of her and noted her progress with the slow-moving file across the end of the room; then I saw her start up the side, and this gave me a full front view of her face. I saw her last when she was within twenty-five feet of me. For an hour I kept thinking she must still be in the room somewhere and would come at last, but I was disappointed. When I arrived in the lecture-hall that evening some one said: “Come into the waiting-room; there's a friend of yours there who wants to see you. You'll not be introduced--you are to do the recognizing without help if you can.” I said to myself: “It is Mrs. R.; I shan't have any trouble.” There were perhaps ten ladies present, all seated. In the midst of them was Mrs. R., as I had expected. She was dressed exactly as she was when I had seen her in the afternoon. I went forward and shook hands with her and called her by name, and said: “I knew you the moment you appeared at the reception this afternoon.” She looked surprised, and said: “But I was not at the reception. I have just arrived from Quebec, and have not been in town an hour.”
