This collection consists of a single ledger maintained by John Brown, a resident of Camden, Maine, in the mid-19th century. Identified as "Account Book No. 5," the ledger contains entries suggesting that Brown operated a lime kiln, with many documenting payments made for the hauling of lime and of wood for the kiln. Elsewhere, Brown lists rents paid for a kiln. Other entries relate to payments for carpentry, for farmwork, and for goods purchased. Inserted in the ledger are a number of bills and receipts.
