Pencil lines radiating from trigonometrical stations cover this drawing. They show the angles used for measuring distances and plotting topographical features. To the left of the map on Chestnut Common, the word 'flag' denotes the site of such a station. Hoddesden Park Wood and surrounding woodland are shown by individual trees with a line at the base, indicating shadow. This laborious technique was often replaced by a more generalised, stippled representation of treetops. The Lee River, running from Standstead at the top of this drawing, branches to form a canal leading down to the Powder Mills, which manufactured Gun Powder for shipping to London. Locks on the canal are shown in red
