This slide show displays pages from a recently discovered financial ledger detailing nearly a century of salary and mileage payments to senators, from 1790 to 1881. The ledger begins with an introductory page, written by Secretary of the Senate Anson McCook in 1884. Samuel Otis, the first Secretary of the Senate, began the ledger in 1791. McCook had the volume restored and rebound in 1884. Rediscovered late in 2002, the volume has now been digitized and transferred to the National Archives for preservation. Blank pages of the volume have not been reproduced here.
