William Plumer’s Memorandum of Proceedings in the United States Senate, 1803-1807

William Plumer of New Hampshire merits the recognition of historical students along with those other pioneer diarists of the United States Senate because his Memorandum is an almost daily record of sessions in the Senate from October 17, 1803, when Congress convened in special session to consider the treaty and conventions with France respecting the purchase of Louisiana, until the close of his term in March 1807.
