Lines in pencil and red ink radiate from trigonometrical stations within the drawing and from the margins. Chelmsford is the largest settlement in the area. A straight, unmarked Roman road leads out from the city. The fact that the road is coloured yellow suggests it was still considered a major communication route. Three mills are marked on the River Chelmer. Marshland along the riverbanks is indicated by rows of dashes, differentiating it from the surrounding cultivated land. A lake and individual trees in the grounds of Moulsham Hall are recorded, towards the bottom of the landmass, a reminder of the meticulous nature of the Survey.
