Manual training--play problems; constructive work for boys and girls based on the play interest
A 1917 Macmillan manual-training textbook by William Samuel Marten, written for American schoolteachers guiding boys and girls in building toys, games and playground equipment from wood. The 165 plates are line-drawn working plans on tinted paper: top, side and end views with dimension arrows, scale bars, hatched joints and dashed hidden edges, useful for technical-drawing motifs and measured diagram conventions.
