Somerset Roller Mills

Tradition holds that Isaac Smith received a 1,000 acres (400 ha) land grant in 1726 from the English Crown. It is thought that shortly thereafter he built the first house and mill on the site, shipping processed grain down the river to Philadelphia. It is probable that the mill provided flour to the Continental Army during the American Revolution. The opening of the Delaware and Raritan Canal next to the mill in 1834 greatly improved its business, leading to its expansion in the 1840s. The mill continued in operation until the early Depression by which point modern automated mill technology rendered its manual operations obsolete. The mill documents the beginnings, development, and decline of a pre-20th century rural manufacturing process.^[3]
