The volume from Dixon's pen which has had most influence is "The Leopard's Spots," the accuracy of which is marked by such assertions as that Congress made a law which gave "to India and Egypt the mastery of the cotton markets of the world"; and that it cost $200,000,000 to pay the United States troops in the South in the year 1867. The book has been traversed with great skill by a negro writer. When Dixon asks: "Can you change the color of the Negro's skin, the kink of his hair, the bulge of his lip or the beat of his heart with a spelling-book or a machine?" Kelly Miller replies: "You need not be so frantic about the superiority of your race. Whatever superiority it may possess, inherent or acquired, will take care of itself without such rabid support.... Your loud protestations, backed up by such exclamatory outbursts of passion, make upon the reflecting mind the impression that you entertain a sneaking suspicion of their validity." Many Southern writers are disposed to put their problems into the form of novels, and there are half a dozen other stories nearly all having for their stock in trade the statutes of Reconstruction, the negro politician who wants to marry a white woman, and the vengeance inflicted on him by the Ku Klux. In the latest of these novels the President of the United States is pictured as dying of a broken heart because his daughter has married a man who is discovered to be a Negro. A book very widely read and quoted in the South is Frederick L. Hoffman, "Race Traits and Tendencies" ("Am. Economic Association Publications," xi, Nos. 1, 2, and 3, 1896). "Race Traits" is written by a man of foreign extraction who therefore feels that he is outside the currents of prejudice; it is well studied, scientifically arranged, and rests chiefly on statistical summaries carefully compiled. The thesis of the book is that the Africans in America are a dying race, but many of the generalizations are based upon statistics of too narrow a range to permit safe deductions, or upon the confessedly imperfect data of the Federal censuses.
