Conductor

Conductor (a leader) generally signifies the leader of the music in the opera or in concerts. Their practice of conducting music by the wielding of a baton is of comparatively late introduction. The name is also applied to the person in charge of a public vehicle, whose duty it is to collect fares and to signify to the driver when to go on and when to stop. On some English railways a kind of superior guard upon certain important trains is sometimes called a conductor; and of late years Messrs. Cook have made us acquainted with personally-conducted travelling parties.
