Today I was loaned all three volumes of /The Boy Mechanic/. They were published in 1913, 1915, and 1919. In Book 2 the first article is "Plane Table Surveying," by Harold G. McGee. This one is the only thing I have found so far about maps, but from a two-minute glance at each of them, drafting and drafting tools are a part of being a boy a century ago. Might there be any interest in republishing articles like this, about how to make maps at home? I can imagine it being done in some high schools. I'll try to have the pages copied (my scanner is dead), but I will have these books for only a few days.
