Here we learn where a ghost's true reception chamber is, where a ghost draws its nectar, as well as why a sanitary engineer is your only exorcist: "There are many houses in Great Britain which have inherited evil reputations; there is a 'ghost's room,' or 'a ghost's corridor,' or 'a ghost's tower,' or 'a ghost's terrace.'  The true ghost's walk is, however, in the basement; amongst and through foetid drains and foul sewers, the ghost's reception-chambers are ancient cesspools, and the ghost's nectar is drawn from tainted wells and neglected water cicterns.  There are British ghosts; but there are also continental ghosts, if possible, more terrible: the chilling palaces of Italy, the gilded splendours of Paris, are alike ghost-haunted.  Your only exorcist is the sanitary engineer."  From All the Year Round, 1861.
