History: Abbott's Grist Mill

In 1802, Nathan Willey built and operated a grist mill near Milford, DE. Upon his death in 1812, the mill was sold to James Owens and then to Isaac Riggs. From 1821 to 1874, it was owned by Johnson family members and others. The core of the present building is believed to be have been constructed on the foundation of the original structure during the later portion of the 19th century.

In 1919, the site became Abbott's Mill when it was purchased by Ainsworth Abbott, a miller. Mr. Abbott operated the mill until 1960, delivering flour weekly throughout the region. He was the sole operator. Abbott's Mill could produce 10-12 barrels of flour per day (a barrel of flour weighed 195 pounds). The mill also shelled, cracked and graded corn and produced ground feed for livestock. Abbott used the "3-break method" of milling, a "break" being one stage in the reduction of grain to flour.

In 1963, Abbott's Mill was acquired by the State of Delaware, placed on the National Register of Historic Places in 1973, and renovated by the State Division of Historical and Cultural Affairs. Adjoining property was added to the Register in 1979.

In 1981, the State leased the site to Delaware Nature Society to become part of the organization's Abbott's Mill Nature Center. A non-profit membership organization, the Nature Society fosters understanding, appreciation and enjoyment of the natural world through education, preserves ecologically significant areas and advocates the stewardship and conservation of natural resources.

Today, the preserved grain mill, 1905 house, stable and outbuilding stand at the northern end of Abbotts Pond, a public fishing pond. The machinery dates back to the 19th century and includes both mill stones and roller mills. Originally the mill was powered by a wooden water wheel, probably of the over-shot type. This was later replaced by a water turbine made of iron.

Though the mill is not open to the public except during Autumn at Abbott's Mill Festival (the 3rd Saturday in October) and other special occasions, tours to see the non-operating machinery may be arranged by calling Abbott's Mill Nature Center, (302) 422-0847. The fully operational machinery is in excellent condition and efforts are underway to provide "living history" experiences.
