“A letter for me?” and Bonnie Belle looked out of the coach-window with surprise at the man, who was dressed as an army courier, and was well mounted.

“Are you Bonnie Belle, miss?”

“Yes, I am so called.”

“Of Yellow Dust Valley?”

“Yes, of Pocket City.”

“I have a letter, then, for you, miss.”

“Who has sent me a letter?”

“Its reading will tell you, miss.”

“You are not from the Yellow Dust country?”

“No, miss, I am from the fort at Pioneer Post.”
