General
In 1794 cartographer John Cary was commissioned by the Postmaster General to survey England's roads, resulting in successive editions of Cary's New Itinerary giving the mileages of the main roads, very helpful for working out pre-1840 mileage-based rates. The 1802 volume was used by Alan Robertson in working out his list of mileages.
The volumes by Army officer and cartographer Daniel Paterson also list roads and distances, with a table of postage rates to places from London, and may or may not have involved some plagiarism from Cary!
