G.S.Callender has written short introductions to the various chapters of his "Selections from the Economic History of the United States" (1909), which are brilliant interpretations of great value.

P.J.Treat's "The National Land System, 1785-1820" (1910), gives the most satisfactory account of the subject indicated by the title.

Of entirely different character is Theodore Roosevelt's "Winning of the West," 4 vols.

(1889-96; published subsequently in various editions), which is both scholarly and of fascinating interest on the subject of the early expansion into the West.
On the most important subject of all, the formation of the Constitution, the material ordinarily wanted can be found in Max Farrand's "Records of the Federal Convention," 3 vols.

(1910), and the author has summarized the results of his studies in "The Framing of the Constitution" (1913).
C.A.Beard's "An Economic Interpretation of the Constitution of the United States" (1913) gives some interesting and valuable facts regarding economic aspects of the formation of the Constitution, and particularly on the subject of investments in government securities.
There is no satisfactory account of the adoption of the Constitution, but the debates in many of the State conventions are included in Jonathan Elliot's "Debates on the Federal Constitution," 5 vols.
(1836-1845, subsequently reprinted in many editions).
A few special works upon the adoption of the Constitution in the individual States may be mentioned: H.B.Grigsby's "History of the Virginia Federal Convention of 1788," Virginia Historical Society Collections, N.S., IX and X( 1890-91); McMaster and Stone's "Pennsylvania and the Federal Constitution, 1787-88" (1888); S.B.
Harding's "Contest over the Ratification of the Federal Constitution in the State of Massachusetts"(1896); O.G.Libby's "The Geographical Distribution of the Vote of the Thirteen States on the Federal Constitution, 1787-1788" (University of Wisconsin, "Bulletin, Economics, Political Science, and History Series," I, No.
