And all allegations, intimations, and inuendoes, that my vote on that occasion was offered to be given, or was in fact given, in consideration of any stipulation or understanding, express or implied, direct or indirect, written or verbal,--that I was, or that any other person was not, to be appointed Secretary of State; or that I was, or in any other manner to be, personally benefitted,--are devoid of all truth, and destitute of any foundation whatever." Here was a direct collision between Gen.

Jackson and Mr.Clay.All now rested with Mr.Buchanan.His testimony would either prostrate Mr.Clay, or place him, in regard to this matter, beyond the reach of the foulest tongue of calumny.

In due time Mr.Buchanan made his statement, in which he denied, in unequivocal language, having made any such proposition to Gen.Jackson.In his explanation he says:-- "I called upon General Jackson solely as his friend, upon my individual responsibility, and not as the agent of Mr.Clay, or any other person.

I never have been the political friend of Mr.Clay, since he became a candidate for the office of President.

Until I saw General Jackson's letter to Mr.Beverly, of the 6th ult., and at the same time was informed, by a letter from the editor of the United States Telegraph, that I was the person to whom he alluded, the conception never once entered my head, that he believed me to be the agent of Mr.Clay, or of his friends, or that I had intended to propose to him terms of any kind from them, or that he could have supposed me to be capable of expressing the opinion that 'it was right to fight such intriguers with their own weapons.' Such a supposition, had I entertained it, would have rendered me exceedingly unhappy, as there is no man on earth whose good opinion I more valued than that of General Jackson.
