Elements of surveying and levelling; with descriptions of the instruments and the necessary tables
A surveying and levelling textbook by Charles Davies, published by A. S. Barnes in New York and Chicago in 1870 for students and field practitioners. Line diagrams show traverse polygons lettered A–E with compass points, dotted offset and coordinate lines, and hatched cross-sections of cut and fill with spot elevations; useful as technical linework, measured notation, and ground-profile motifs.
