The relations of the United States and Spanish Florida are set forth in many works, of which three only need be mentioned: H. B. Fuller, "The Purchase of Florida" (1906), has devoted several chapters to the early history of the Floridas, but so far as West Florida is concerned his work is superseded by I. J. Cox's "The West Florida Controversy, 1789-1813" (1918). The first volume, "Diplomacy," of F. E. Chadwick's "Relations of the United States and Spain," 3 vols. (1909-11), gives an account of the several Florida controversies. Several books contribute to an understanding of the temper of the young insurgents in the Republican Party: Carl Schurz's "Henry Clay," 2 vols. (1887), W. M. Meigs's "Life of John Caldwell Calhoun," 2 vols. (1917), M. P. Follett's "The Speaker of the House of Representatives" (1896), and Henry Adams's "John Randolph" (1882).
