1 : 21120 This rough field sketch, or 'foul' copy, was produced on several pieces of irregularly cut paper joined together and laid on the verso of the triangulation map for southern England. Covering the north side of the Thames, East Ham and Ilford are to the left, and Rainham to the right. The drawing is dominated by a patchwork of field boundaries, with open dotting indicating unproductive enclosed land. The detail recorded here was incorporated in the 'fair' map OSD 132, titled 'Barking'.
1 : 21120 This plan of the north side of the Thames shows Barking and Ilford to the left, on the banks of the Roding, and Rainhham and Hornchurch to the right. A patchwork of field boundaries dominate the landscape, with open dotting depicting unproductive enclosed land. Pencil lines intersect across the plan, recording the angular measurements taken by the surveyor to calculate the distances between fixed points in the landscape.
Triangulation lines radiating from fixed points are clearly visible on this map. A pecked red line running adjacent to Lee River marks the boundary separating Essex from Hertforshire and Middlesex. Henhault Forest is shown by a stippled canopy of tree tops at the centre of the drawing. Perhaps the most interesting detail on this map is just south of the forest: a small drawing of a tree inside an enclosure marked 'Fairlop Oak'. This giant oak tree was something of a local landmark. In 1791, William Forsyth, gardener to George III, made unsuccessful attempts to halt the tree's decline. The year that this map was published, the tree was badly burnt by a fire started during a picnic. Its health steadily continued to wane until it was blown down in a gale in 1820. The inclusion of details such as the Fairlop Oak reveals the meticulous nature of the Survey, and the great attention paid to local detail. Budgen, Charles
MAP of the COUNTRY 15 MILES ROUND London SHEWING BY A YELLOW CIRCLE OF 3 MILEs, THE LIMITS OF THE TWOPENNY POST DELIVERY
This map was commissioned by the House of Commons for the ninth report of the Post Office Management. The map's title features at top right, with an explanatory note and scale bar at bottom right. It shows the boundaries of the London Two-Penny Post, and the old and current boundaries of the Country Three-Penny Post, with mail routes highlighted in red. Post stages on the edges of the post area allowed mail to be exchanged between the London and the General Post on all main roads out of London. Wyld, James
THE ENVIRONS OF LONDON
This map of London and part of the Home Counties was published in Pinnock's 'Guide to Knowledge'. Reduced from an original Ordnance Survey drawing, the map is printed in white on black, with the title in inset table at top centre. Though none of the sheets of the first edition of the Ordnance Survey covered London, part of the metropolitan area was contained in the maps of Middlesex, Essex, Surrey and Kent issued between 1805 and 1822.
