A collection of account, cash, inventory, and letter books belonging to merchant Peter Verstille of Wethersfield and Hartford, Connecticut. Invoices in the first volume list goods, consigned to Peter Verstille, that are being shipped to Boston. Items include clothing, books, a barrel of indigo, yellow china, and beaver coating. Verstille has also recorded items purchased in Boston. A later portion of the first volume contains tables of measure. William Verstille would later use the book for handwriting practice. Recorded in Volume 2 are trades with shopkeepers, merchants, tavernkeepers, a silversmith, and others, in Portsmouth, New Hampshire. Volume 3 is primarily an inventory of Verstille's goods. Later volumes contain records of cash transactions, and one pertains to Delftware. One volume is partly a commonplace book. The style of bookkeeping changes in the later volumes, indicating a possible shifting of responsibility to the next generation.
