They include royal correspondence, household accounts and portraits of previous Princes of Wales.<\/p>\n\n\n\n<p>Our historians were searching for a different kind of treasure, however. To reconstruct past land-use and agricultural practice on Duchy landholdings, we examined maps, surveys, farm accounts, rentals and the famous Duchy Assession Rolls.<\/p>\n\n\n\n<p>The latter record the size (in English <em>and<\/em> Cornish acres), tenants and rents of properties in the Duchy\u2019s Assessionable manors, typically every seven years. In practice, this meant photographing and deciphering long, multi-sided vellum rolls written in Latin until around 1735.<\/p>\n\n\n\n<p>A Cornish acre was a customary rather than statute acre. It is therefore varied by location, but was as large as 120 or as small as 64 statute (or modern) acres.<\/p>\n\n\n\n<p>We have now completed the \u2018backbone\u2019 of this initial data gathering and have begun digging deeper into our chosen case studies. This will involve locating sources, such as leases and accounts, which are particular to the farms we have chosen to study.<\/p>\n\n\n\n<p>Our work has benefitted immensely from the insights and expertise of the Duchy of Cornwall\u2019s archive staff.
