When the handkerchief came out a sheet of paper, folded and crumpled, fluttered toward the floor, describing an eccentric circle and landing within a foot of Mary's feet.
The girl saw that Sanderson had not noticed the loss of the paper, and she stooped and recovered it.

She held it in a hand while Sanderson continued to wipe the perspiration from his face, and noting that he was busily engaged she smoothed the paper on the table in front of her and peered mischievously at it.

And then, her curiosity conquering her, she read, for the writing on the paper was strangely familiar.
Sanderson having restored the handkerchief to its pocket, noticed Mary's start, and saw her look at him, her eyes wide and perplexed.
"Why, Will, where did you get this ?" she inquired, sitting very erect.
"Mebbe if you'd tell me what it is I could help you out," he grinned.
"Why, it's a letter father wrote to a man in Tombstone, Arizona.

See here! Father's name is signed to it! I saw father write it.

Why, I rode over to Dry Bottom and mailed it! This man had written to father a long time before, asking for a job.
