Surveying field notes / 1899
This is a manuscript surveying field notebook from 1899, compiled by D. Th. Macdougall and later owned by L. Leland Locke, held by the Smithsonian Libraries after donation by Grove City College. The notebook is aimed at working surveyors recording measurements in the field. The one picture is a hand-ruled plan in brown ink on cream paper, with dimensioned lines, angled boundaries and a red vertical margin rule, labelled 'Mechanical lab' at the foot. A designer could take its sparse, technical linework and handwritten dimension figures as a model for diagrammatic annotation and architectural layout.
