Jerome of a boating holiday on the Thames between Kingston and Oxford. The book was initially intended to be a serious travel guide, with accounts of local history along the route, but the humorous elements took over to the point where the serious and somewhat sentimental passages seem a distraction to the comic novel. One of the most praised things about Three Men in a Boat is how undated it appears to modern readers, the jokes seem fresh and witty even today.</dc:description>"
