   Every now and then, young readers would write to ask how I could, as I put it, "make improvements" on "a good many things in this history" that had been told me "by fine honest Americans," and how I could "truthen up" facts. I gave them elaborate metaphysical explanations which I'm not sure that they — or even I — completely understood. If my claims made sense, I suppose that those technical facts about heroes' occupations and background historical facts deserve some credit. Also, I like to believe that I truthened up my history by satirizing some vulnerable aspects of American life; for example, the way some entrepreneurs interlace smug piety and sharp practices; the crassness and cruelty of some hair-trigger toughs; Johnny Appleseed's self-righteousness and sentimentality; undemocratic practices; super efficiency combined with inhumanity and pretentiousness.
