This 1916 book extols the wisdom of teaching girls to use their hands for more than cooking and sewing. Of course there are always some people bucking the status quo, but I wonder about the timing here. WW I was rearing it's ugly head at us. If we got in deep, who would produce the materiel and tend the home front? I don't think that came about until WW II, but manual arts training might be good for the industrial boom coming post war. A bigger potential labor force helps keep wages down.
Or it could be some do-gooder trying to help the oppressed, although the money in that is mostly in selling the book. Cynical? Moi?
