The Fate of a Crown by L. Frank Baum

Leaning back in my chair, I smoked my morning cigar and watched Uncle Nelson open his mail. He had an old-fashioned way of doing this: holding the envelope in his left hand, clipping its right edge with his desk shears, and then removing the inclosure and carefully reading it before he returned it to its original envelope. Across one end he would make a memorandum of the contents, after which the letters were placed in a neat pile.

As I watched him methodically working, Uncle Nelson raised a large blue envelope, clipped its end, and read the inclosure with an appearance of unusual interest. Then, instead of adding it to the letters before him, he laid it aside; and a few minutes later reverted to it again, giving the letter a second careful perusal. Deeply musing, for a time he sat motionless in his chair. Then, arousing himself from his deep abstraction, he cast a fleeting glance in my direction and composedly resumed his task.
