Farmers and other rural folk are often pictured as distant from financial centres and invoked as the last groups to monetise their transactions during a long process of modernisation. By treating grain as money and by comparing barns to banks, Chapter 2 raises important questions about this accepted picture and about the boundaries of financial history as a discipline. This chapter explores how a community in the east of the Dutch Republic sowed, tended to, harvested, stored, and kept track of grain. People sustained the material integrity of grain, but more importantly, they also sustained grain’s ability to act as currency in social interaction. Volume measures, owned privately but calibrated by local authorities, were key for the monetisation of grain. Furthermore, the chapter introduces the notion of ink money, normally associated with urban merchants and bankers who made and unmade money by formal accounting, in order to make sense of farmers’ finance in the Dutch countryside. Unlike trade among merchants, where both parties could produce ledgers when challenged, farmers keeping accounts often dealt with illiterate people. These account books provide indirect evidence that day-labourers and smallholders could record and transact monetary value by way of mental accounting. This money was more precarious than its written counterparts, but could be validated by oral testimonial in local courts.
