These two companion plans exhibit a great deal of detailed information. Jefferys' boast that much of the information was "Not extant on any other Plan" is in many ways borne out by the numerous tables, which contain information on the Great Offices of State, such as the master of the horse and the Board of Green Cloth; the Chief Magistrates of Westminster; and, most interestingly, the Parishes in Surrey and Middlesex which were in and outside the boundaries of the Bills of Mortality. The Bills of Mortality were set up at the end of the sixteenth century, in response to an outbreak of the plague. They initially recorded the number of deaths upon a weekly basis, however by the time of the publication of the map the bills included baptisms, cause of death and age of the deceased. The plan also shows the newly built Westminster and Blackfriars Bridges, together with the new roads. The Savoy is marked (later the site of the hotel) as belonging to the Duchy of Lancaster. The Duchy then, as now, is used to provide income for the British monarch.
