the theme that I could gleam from this excerpt is a theme of humility in the very end of the story a man came to see Jefferson but the landlord thought that the vice president was just some farmer covered in dirt and mud.

Rewrote in another words

The prevailing theme conveyed in this excerpt is that of humility. At the conclusion of the story, when a man arrives to visit Jefferson, the landlord mistakenly assumes that the vice president is a mere farmer, due to his appearance being covered in dirt and mud.
