When I have been indulging this thought I have, in imagination,
seen the Britons of some future century, walking by the banks of
the Thames, then overgrown with weeds and almost impassable with
rubbish. The father points to his son where stood St. Paul's,
the Monument, the Bank, the Mansion House, and other places of
the first distinction.
