Although Across the River and into the Trees takes place entirely in Venice and the surrounding region, Long argues that the presence of America is often evoked, emphasizing the difference of new world and old world, Europe and America, and present and past. The protagonist, Colonel Cantwell, has a foil in his chauffeur, the American Jackson, who does not appreciate the subtle values of the Italians. Jackson, to Long, represents the unenlightened mainstream American mindset. On the other hand, Long also points to moments where Cantwell idealizes America, looking toward a wonderful future upon his return with his Italian girlfriend, Renata.
