d. A surveyor's field tent

In a surveyor’s field tent, the table is laid out to complete several surveys in progress. A selection of drafting tools stand ready to produce the line drawings: a graphite crayon to serve as a pencil, ruling pens to ink the final lines, parallel rules for drawing straight lines, compasses (dividers) for transferring equal distances exactly on a drawing, parallel rules, a scale to transfer proportions from one scale to another, and watercolors to create a more readable and usable final product. All this is needed to render field notes of distances and direction measured into usable surveys and maps.
