tenor of Southern opinion was changed, and the Democracy of that section received a new inspiration. Mr. Van Buren, aspiring again to the Presidency, desired to avoid the Texas issue. Mr. Calhoun determined that he should meet it. He had every motive for distrusting, opposing, even hating, Van Buren. The contest between them had been long and unrelenting. When Van Buren, as secretary of State, was seized with the ambition to succeed Jackson, he saw Calhoun in the Vice-Presidency, strongly intrenched as heir-apparent; and he set to work to destroy the friendship and confidence that existed between him and the President. The rash course of Jackson in the Seminole campaign of 1818 had been severely criticised in the cabinet of Monroe, and Mr. Calhoun, as secretary of War, had talked of a court of inquiry. Nothing, however, was done and the mere suggestion had been ten years forgotten, when Jackson entered upon the Presidency, entertaining the strongest friendship, both personal and political, for Calhoun. But the damaging fact was unearthed and the jealousy of Jackson was aroused. Calhoun was driven into a deadly quarrel, resigned the Vice-Presidency, and went back to South Carolina to engage in the nullification contest. Van Buren quickly usurped his place in the regard and confidence of Jackson, and succeeded to the Presidency. Calhoun, denounced in every paper under the control of the administration, was threatened with prosecution, and robbed for a time of the confidence of the Democratic party. By the strangely and rapidly changing fortunes of politics, it was now in his power to inflict a just retribution upon Van Bren. He did not neglect the opportunity. SECRETARY CALHOUN'S DIPLOMACY.
