the old State rights ground. His change of personal relation, which gave so much concern to the senator, so far from involving any change in his principles or doctrines, grew out of them." The latter part of this reply of Mr. Calhoun is worthy of universal acceptance, and perpetual remembrance. The real source of all the disorders to which the country was, or had been subject, was in the system of legislation which encouraged the industry of one part of the Union at the expense of the other--which gave rise to extravagant expenditures, to be expended unequally in the two sections of the Union--and which left the Southern section to pay the expenses of a system which exhausted her. This remarkable declaration of Mr. Calhoun was made in 1839--being four years after the slavery agitation had superseded the tariff agitation,--and which went back to that system of measures, of which protective tariff was the main-spring, to find, and truly find, the real source of all the dangers and disorders of the country--past and present. Mr. Clay replied: "He had understood the senator as felicitating himself on the opportunity which had been now afforded him by Mr. C. of defining once more his political position; and Mr. C. must say that he had now defined it very clearly, and had apparently given it a new definition. The senator now declared that all the leading measures of the present administration had met his approbation, and should receive his support. It turned out, then, that the rumor to which Mr. C. had alluded was true, and that the senator from South Carolina might be hereafter regarded as a supporter of this administration, since he had declared that all its leading measures were approved by him, and should have his support. As to the allusion which the senator from South Carolina had made in regard to Mr. C.'s support of the head of another administration [Mr. ADAMS], it occasioned Mr. C. no pain whatever. It was an old story, which had long been sunk in oblivion, except when the senator and a few others thought proper to bring it up. But what were the facts of that case? Mr. C. was then a member of the House of Representatives, to whom three persons had been returned, from whom it was the duty of the House to make a selection for the presidency. As to one of those three candidates, he was known to be in an unfortunate condition, in which no one sympathized with him more than did Mr. C. Certainly the senator from South Carolina did not. That gentleman was therefore out of the question as a candidate for the chief magistracy; and Mr. C. had consequently the only alternative of the illustrious individual at the Hermitage, or of the man who was now distinguished in the House of Representatives, and who had held so many public places with honor to himself, and benefit to the country.
