Jules Prown, a professor of art history at Yale University, and has done much of his scholarly writing on a property in Ryegate he has owned since 1972. The land was once a small hill farm used as a dairy, and Jules has continued to lease the meadow to farmers for hay. And, for more than 30 years, he has managed a 1,200-tap sugaring operation with Frank Page, whose grandfather had owned the farm before Jules. This year, Jules decided to donate a conservation easement on 148 acres of the property to ensure it would remain undeveloped. In addition to 42 acres of excellent farm soils, the land has 110 acres of managed forest, the headwaters of Tannery Brook (a Wells River tributary), and a number of open and forested wetlands.
