Topographic maps and sketch mapping
A 1920 instructional manual on topographic mapping and field sketching by James Kip Finch, issued in New York by John Wiley & Sons for surveying students and military engineers. The plates are stark pen-and-ink diagrams: dashed construction lines, numbered and lettered survey points, angle arcs, diagonal scale layouts, and hachured hill-and-valley sketches, useful as ready-made geometric line art, map shorthand, and technical marginal figures.
