A series of candid letters from an experienced salesman to his son traces practical instruction and personal encouragement as the son advances from a novice cub to branch and district responsibilities. The father combines trade anecdotes, concrete techniques—calling on all merchants, teamwork, advertising, contest strategy—with moral counsel about appearance, temperance, handling promotions, and marriage decisions, illustrating lessons through promotions, setbacks, and managerial challenges. The collection mixes humorous verse and real-world examples to teach salesmanship, leadership, and professional conduct.
