Near Wilmington in New Castle County, Delaware — The American Northeast (Mid-Atlantic)
Farm Equipment
Built 1910-1940s
With the opening of Alfred I. duPont Institute in 1941, much of the food raised at Nemours Estate now went to the hospital. "We grew a lot of vegetables for the hospital during the war," recalled Thomas A. Newman, who oversaw the estate's farming operations. "In the fall when there were plenty of apples, every Friday we made 20 gallons of cider for the hospital, and there were gallons and gallons of applesauce made."
By the 1940s, as package stores and grocers were built along Concord Pike, Nemours Estate's needs for food production greatly diminished. Local dairy farmers leased Blue Ball Farm until the 1970s; in 1999, the State of Delaware purchased it. Blue Ball Barn has been restored and now houses a display of Delaware folk arts.
