Sawyer is something of a rowdy version of Alfred Jingle; a young man completely without parental guidance. He would like to marry Arabella Allen and have her money, but he also genuinely likes her. He is inventive, coming up with several ingenious, hapless tricks to increase his medical practice. Like Jingle, he is always hoping for easy money, enjoys practical jokes, and is quick to strike up acquaintances. Sawyer maybe a failure — improvident, hard drinking, slovenly, boisterous, impulsive — but he enjoys life and the reader responds to his uncouth charm.
