Two anthropomorphic bear companions leave their mountain home to tour the eastern United States, encountering a series of comic, episodic adventures. They ride trains and Pullman cars, cause mischief on a Kansas farm, visit schools, fairs, circuses and vaudeville shows, sail near Niagara Falls and Chicago, take a balloon flight, and explore Boston, Harvard and other city sights. Along the way their playful antics encourage sympathy for animals and amuse young readers, presented in jaunty verse and illustrated scenes that alternate travelogue episodes with slapstick and gentle lessons about curiosity and kindness.
