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 have just arrived from Quebec, and have not been in town an hour.” It was my turn to be surprised now. I said: “I can’t help it. I give you my word of honor that it is as I say. I saw you at the reception, and you were dressed precisely as you are now. When they told me a moment ago that I should find a friend in this room, your image rose before me, dress and all, just as I had seen you at the reception.” Those are the facts. She was not at the reception at all, or anywhere near
