A treatise on surveying and navigation: uniting the theoretical, practical, and educational features of these subjects
Horatio N. Robinson's 1857 textbook on surveying and navigation, issued in Cincinnati and Toledo for American schoolrooms and working surveyors. The 103 figures are geometric diagrams printed as white lines and italic letter labels on solid inked grounds, giving reversed-out triangles, quadrilaterals, arcs and dashed sight lines that can be lifted as high-contrast line motifs or overlaid on dark fields.
