For the Fourteenth Amendment: C.G. Haines, _American Doctrine of Judicial Supremacy_ (1914); C.W. Collins, _The Fourteenth Amendment and the States_ (1912), is a careful study, which is critical of the prevailing later interpretation of the Amendment. The Slaughter House case, giving the earlier interpretation is in J.W. Wallace, _Cases argued and adjudged in the Supreme Court_ (Supreme Court Reports), XVI, 36. L.H. Haney, _History of Economic Thought_ (1911), on _laissez faire_; J.L. Laughlin, _Principles of Money_ (1903); and Irving Fisher, _Why is the Dollar Shrinking_ (1914), present two sides of the quantity theory of money. Most useful on the development of education are F.P. Graves, _A History of Education in Modern Times_ (1913); and E.G. Dexter, _History of Education in the United States_ (1904). The growth of newspapers is described in _The Bookman_, XIV, 567-584, XV, 26-44; see also Rollo Ogden, _Life and Letters of Godkin_, already mentioned; G.H. Payne, _History of Journalism in the United States_ (1920); J.M. Lee, _History of American Journalism_ (1917). The effects of education and the press on American social, economic and political life have not been subjected to thorough study. * * * * * [1] _Addresses on Government and Citizenship_, 202.

CHAPTER V THE NEW ISSUES Out of the economic and political circumstances which have just been described, there were emerging between 1865 and 1875 a wide variety of national problems. Such questions were those concerning the proper relation between the government and the railroads and industrial enterprises; the welfare of the agricultural and wage-earning classes; the assimilation of the hordes of immigrants; the conservation of the resources of the nation in lumber, minerals and oil; the tariff, the financial obligations of the government, the reform of the civil service, and a host of lesser matters. The animosities aroused by the war, however, and the insistent nature of the reconstruction question almost completely distracted attention from most of these problems. Only upon the tariff, finance and the civil service did the public interest focus long enough to effect results.
