I know of no abler and more candid life of Calhoun than that of Von Holst. Although deficient in incidents, it is no small contribution to American literature, apparently drawn from a careful study of the speeches of the great Nullifier. If the author had had more material to work upon, he would probably have made a more popular work, such as Carl Schurz has written of Henry Clay, and Henry Cabot Lodge of Daniel Webster and Alexander Hamilton. In connection read the biographies of Clay, Webster, and Jackson; see Wilson’s History of the Rise and Fall of the Slave Power, also Benton’s Thirty Years of Congressional History, and Calhoun’s Speeches.
