Fonds relates to Job Anderson and his blacksmith shop. Fonds contains one volume of early accounting records. This ledger appears to have been used by at least two different people, conducting two different types of business in and around Sackville, New Brunswick. The ledger dates to 1893 and is possibly the account book of Blacksmith Job Anderson because he wrote that the account had been paid in full on 7 January 1904. The second set of entries in the ledger began in 1908 and does not specify blacksmithing. The unidentified record keeper has entered, in daybook style, all expenditures and receipts for work he completed, items he purchased, and payments he received. The entries indicate a farm operation and continue until 1933. There are other accounting records, including some expenses and ledger entries from 1896 near the end of the ledger. (OS Shelf 2)
