A treatise on surveying and navigation: uniting the theoretical, the practical, and the educational features of these subjects
Horatio Nelson Robinson's 1852 textbook on surveying and navigation, published in Cincinnati by J. Ernst for American students and working surveyors. The ninety wood engravings are white-line geometric diagrams printed as light strokes on solid black blocks: labelled triangles, sight lines, angles and lettered points, useful as stark high-contrast linework, technical ornament, or ready-made negative-space figures.
