Elements of surveying and leveling
Elements of surveying and leveling is Charles Davies's American textbook for students of practical geometry and field survey, issued in this 1898 edition by the American Book Company in New York and Cincinnati. The 137 figures are line diagrams: closed traverse polygons lettered with compass points and offset dashed lines, plus leveling profiles showing hatched ground, sight lines from a tripod symbol, and numbered elevations "" a source of plain technical linework, surveyor's notation, and cross-section hatching.
