It was the "Rev." Mr. Buffington, as he called himself.

His eye lighted up as he saw to whom the letter was addressed.

"So this boy is traveling for a New York jeweler," he said to himself. "I am glad to know this. He probably carries a stock of jewelry with him, and if so, I shall cultivate his acquaintance."

He passed out of the reading room without Mark observing him. Mr. Buffington took care to keep out of the way, and Mark supposed he had left the hotel.


CHAPTER XVIII.

A MIDNIGHT VISIT.

Mark was confirmed in his belief that Mr. Buffington had left the hotel, because on looking over the book he found no such name. It did not occur to him that Lawrence Perkins was his railroad friend under another alias. Mr. Buffington was rich in names, and had masqueraded under at least a dozen. He, however, had seen Mark's name in the register, and noted carefully the number of his room. The information seemed to him important, especially after he had looked over Mark's shoulder and found that he represented a prominent jeweler in New York.

Mark did not fail to keep his appointment at the theater. He arrived first, but five minutes later Mrs. Loring, Florence and a young man, cousin to the latter, made their appearance.

Florence smiled pleasantly, and arranged the party so that Mark should sit beside her.
