Practical draughtsmen's work, with numerous engravings and diagrams
A practical manual on mechanical drawing edited by Paul N. Hasluck, published by D. McKay in Philadelphia in 1903 for tradesmen, apprentices and drawing-office draughtsmen. The line engravings show geometric constructions, plotted site plans with dimension figures, hatched sections, wood-grain shading and set-square shapes, offering designers ready-made hatch fills, dotted measuring lines, degree annotations and letter-labelled diagram keys.
