Young Englishman John Pomfret is making his way through Spain in order to propose to Marie Daguilar, the daughter of his father's partner. En route, he encounters an elaborately dressed Spanish gentleman who he takes to be a bullfighter and assumes can speak no English. John's rudeness and arrogance toward the Spaniard will come back to shame him during a later encounter. 'John Bull on the Guadalquivir' is an entertaining short story from much-loved author Anthony Trollope.-
