George Eighinger received this ledger from Nash G. Camp (b. 1838) on March 4, 1850, and used its empty pages as a copybook for math problems and other material. The book previously belonged to a shipping merchant from Baltimore, Maryland, who imported linen and other goods from Germany and exported coffee, tobacco, and sugar, among other goods, from the Caribbean to Germany, particularly to Bremen.
