He drew over the picture the sheet of thin paper on which I was accustomed to rest my hand in painting, to prevent the cardboard from being sullied. What he suddenly saw on this blank paper, it was impossible for me to tell; but something had caught his eye. He took it up with a snatch; he looked at the edge; then shot a glance at me, inexpressibly peculiar, and quite incomprehensible: a glance that seemed to take and make note of every point in my shape, face, and dress; for it traversed all, quick, keen as lightning. His lips parted, as if to speak: but he checked the coming sentence, whatever it was.

     "What is the matter?" I asked.

     "Nothing in the world," was the reply; and, replacing the paper, I saw him dexterously tear a narrow slip from the margin. It disappeared in his glove; and, with one hasty nod and "good-afternoon," he vanished.

     "Well!" I exclaimed, using an expression of the district, "that caps the globe, however!"

     I, in my turn, scrutinised the paper; but saw nothing on it save a few dingy stains of paint where I had tried the tint in my pencil. I pondered the mystery a minute or two; but finding it insolvable, and being certain it could not be of much moment, I dismissed, and soon forgot it.
