House - things or city courts. London has still its court of Hustings in Guildhall, in which are elected the lord mayor, the aldermen, and city members. The hustings of elections are so called because, like the court of Hustings, they are the places of elective assemblies. (Anglo-Saxon, husting, a place of council.)
