Llanerfyl
1 : 31680 The formal title of the drawing states that Robert Dawson supervised the surveyor. Dawson, one of the best surveyors and draughtsmen, was employed on the Ordnance Survey for over forty years, working also as an instructor. The scale of the drawing is noted and the area of the land recorded as 165.4742 square miles. A triangulation diagram appears on the reverse. This enabled draughtsmen to plot the exact location of topographical features. Colour washes depicting relief are combined with numerical annotations ('spot heights') in black ink indicating the heights of hills. The draughtsman has also distinguished between the representation of coniferous and deciduous trees. Hall, Joseph

The author of the drawing, Robert Dawson, explains that these altitudes were trigonometrically ascertained, "except those distinguished by a note of interrogation, which are only a judgement." One of the best surveyors and draughtsmen, Dawson was employed on the Ordnance Survey for over forty years, also working as an instructor. Dawson, Robert
Llandrillo
1 : 31680 This,original protraction is formally titled. The traverse routes are noted with the relevant dates and Ordnance Survey field-book page numbers. The conventional sign of a dot within a triangle indicates a trigonometrical point. These appear around the edges of the drawing in red ink,,marking the points from which the surveyor took angular measurements to plot features of the landscape. , Collard, Thomas W.
Llangollen
1 : 31680 A triangulation diagram appears on the reverse of this drawing. This enabled draughtsmen to plot the exact location of topographical features. Mileage is indicated on major communication routes, accompanied by abbreviations of the town names from which distance has been measured. For example, the abbreviation 'MS L''2' indicates two miles from Llangollen. Archaeological sites are named in gothic script. A triangulation grid is faintly visible in the left hand portion of the drawing, and pencil lines radiate from trigonometrical stations, marked by dots within triangles. Durrant, William R
