Mr. Calhoun's published works show the extent of his participation in the national councils. They exhibit his zeal, the intensity of his convictions, and at the same time the clearness and strength of his logic. His premises once admitted, it is difficult to resist the force of his conclusions. Mr. Webster assailed his premises, and in their debate of February 16, 1833, defeated him, as another senator remarked, "by the acuteness of his definitions,"--thus meeting Mr. Calhoun on his own ground. The war and its results have in large degree remanded the theories of Mr. Calhoun to the past, but no intelligent student of the institutions of the United States can afford to neglect his elaborate, conscientious, able discussions. Taken with Mr. Webster's works they exhibit the most complete examination, the most comprehensive analysis of the often tortuous and ill-defined line which separates the powers of the National Government from the functions which properly belong to the States. Mr. Calhoun's public service may be regarded as continuous from 1810, when he was elected to Congress at twenty- eight years of age, till his death,--a period of forty years. He took his seat in the House in December, 1811, and was placed by the speaker, Mr. Clay (with whom he was then in accord), on the Committee of Foreign Affairs. He was earnest and influential in supporting the war policy of the Madison administration, and gained so rapidly in public estimation that six years later he was appointed secretary of War by President Monroe. Thenceforward his career was illustrious. As Vice-President, as secretary of State, above all as senator from South Carolina, he gained lasting renown. His life was eminently pure, his career exceptional, his fame established beyond the reach of calumny, beyond the power of detraction. MR. WEBSTER'S 7TH OF MARCH SPEECH.
