A travel-writer recounts his time with two well-known American humorists while they lived and circulated in European cities, presenting a series of anecdotal sketches and recollections. The pieces capture their conversation, mannerisms, and responses to social customs, language, royalty, art, and contemporary personalities; they mix light-hearted episodes, reflections on fame and temperament, and brief critical remarks about literary and political topics. The arrangement is episodic rather than continuous, offering vivid vignettes that illuminate public and private behavior abroad.
