George Washington called this small, leather-bound book a "pocket day book." He used it to record small personal expenditures and receipts of cash. It also includes some entries documenting the larger business of his plantation, such as hiring. Washington later transferred most of the entries in these volumes to his ledger and account books. The blank pages that appear are blotter pages.
There are 72 pages.
