DEAR SIR,--Your letter of December the 19th places me under a dilemma, which I cannot solve but by an exposition of the naked truth. I would have wished this rather to have remained as hitherto, without inquiry; but your inquiries have a right to be answered. I will do it as exactly as the great lapse of time and a waning memory will enable me. I may misremember indifferent circumstances, but can be right in substance. At the time when the republicans of our country were so much alarmed at the proceedings of the federal ascendency in Congress, in the executive and the judiciary departments, it became a matter of serious consideration how head could be made against their enterprises on the constitution. The leading republicans in Congress found themselves of no use there, brow-beaten, as they were, by a bold and overwhelming majority. They concluded to retire from that field, take a stand in the State legislatures, and endeavor there to arrest their progress. The alien and sedition laws furnished the particular occasion. The sympathy between Virginia and Kentucky was more cordial, and more intimately confidential, than between any other two States of republican policy. Mr. Madison came into the Virginia legislature. I was then in the Vice-Presidency, and could not leave my station. But your father, Colonel W. C. Nicholas, and myself happening to be together, the engaging the co-operation of Kentucky in an energetic protestation against the constitutionality of those laws, became a subject of consultation. Those gentlemen pressed me strongly to sketch resolutions for that purpose, your father undertaking to introduce them to that legislature, with a solemn assurance, which I strictly required, that it should not be known from what quarter they came. I drew and delivered them to him, and in keeping their origin secret, he fulfilled his pledge of honor. Some years after this, Colonel Nicholas asked me if I would have any objection to its being known that I had drawn them. I pointedly enjoined that it should not. Whether he had unguardedly intimated it before to any one, I know not; but I afterwards observed in the papers repeated imputations of them to me; on which, as has been my practice on all occasions of imputation, I have observed entire silence. The question, indeed, has never before been put to me, nor should I answer it to any other than yourself; seeing no good end to be proposed by it, and the desire of tranquillity inducing with me a wish to be withdrawn from public notice. Your father's zeal and talents were too well known, to derive any additional distinction from the penning these resolutions. That circumstance, surely, was of far less merit than the proposing and carrying them through the legislature of his State. The only fact in this statement, on which my memory is not distinct, is the time and occasion of the consultation with your father and Colonel Nicholas. It took place here I know; but whether any other person was
