The notes of Yates, King, and Pierce are the only unofficial record of the convention extant, besides Madison's, and their chief value is in connection with the Madison record, which in the main they support, and which occasionally they elucidate. December 30, 1818, Charles Pinckney wrote to John Quincy Adams that he had made more notes of the convention than any other member except Madison, but they were never published and have been lost or destroyed.[5] [5] See p. 22, n. In 1819 (Boston) was published the _Journal, Acts and Proceedings of the Convention_, etc., under the supervision of John Quincy Adams, Secretary of State, by authority of a joint resolution of Congress of March 27, 1818. This was the official journal of the convention, which the Secretary, William Jackson, had turned over to the President, George Washington, when the convention adjourned, Jackson having previously burned all other papers of the convention in his possession. March 16, 1796, Washington deposited the papers Jackson had given him with the Secretary of State, Timothy Pickering. They consisted of three volumes,--the journal of the convention, the journal of the proceedings of the Committee of the Whole of the convention, and a list of yeas and nays, beside a printed draft of the Constitution as reported August 6th, showing erasures and amendments afterwards adopted, and the Virginia plan in different stages of development. In preparing the matter for publication Secretary Adams found that for Friday, September 14, and Saturday, September 15, the journal was a mere fragment, and Madison was applied to and completed it from his minutes. From General B. Bloomfield, executor of the estate of David Brearley, a delegate in the convention from New Jersey, Adams obtained a few additional papers, and from Charles Pinckney a copy of what purported to be the plan of a constitution submitted by him to the convention. All of these papers, with some others, appeared in the edition of 1819, which was a singularly accurate publication, as comparison by the present editor of the printed page with the original papers has shown. The Pinckney plan, as it appeared in this edition of the journal, was incorporated by Madison into his record, as he had not secured a copy of it when the convention was sitting. But the draft furnished to Secretary Adams in 1818, and the plan presented by Pinckney to the convention in 1787 were not identical, as Madison conclusively proved in his note to his journal, in his letter to Jared Sparks of November 25, 1831, and in several other letters, in all of which he showed that the draft did not agree in several important respects with Pinckney's own votes and motions in the convention, and that there were important discrepancies between it and Pinckney's _Observations on the Plan of Government_, a pamphlet printed shortly after the convention adjourned.[6] [6] See P. L. Ford's _Pamphlets on the Constitution_, 419.
