About Fork Factory Brook

Follow a network of trails through wetland, hayfields, and wooded upland to discover views and the foundations of an historic mill.

What makes Fork Factory Brook a special place?
The trails here run over an unexpected diversity of landscapes: wetland, hay fields of the former Long Acre Farm, and wooded hillsides offering views of the surrounding area, and the remains of a 19th-century pitchfork mill. Part of a much larger original farm holding, the fields of Long Acre Farm have been in agriculture for at least 300 years. Throughout the 18th century, it was a classic New England self-sufficient farming operation that pastured livestock, grew crops, and harvested hay.

1.5 miles of trails. Easy hiking.

Year-round, daily, sunrise to sunset. Allow a minimum of 1 hour, 3 hours if also visiting Rocky Woods.

Property History

Throughout the 18th century, Long Acre Farm was a classic New England self-sufficient farming operation that pastured livestock, grew crops, and harvested hay. It also produced rope from hemp, processed flax and wool, made butter and cheese, and used animal byproducts to make candles and boots.

Next to Long Acre Farm, Joshua Morse operated a grist mill along the Mill Brook at least as early as 1771. In 1838–39, Henry Partridge purchased two mills, one on the south side of Main Street (Rte 109) – a cut-nail mill – and one on the north side – Morse’s grist mill. He modified both to create a factory that gives the reservation its name. Partridge and his brother-in-law Malachi Babcock, a blacksmith, had apparently developed a high-quality steel that they used in a Sherborn factory to produce edge tools such as cranberry rakes, adzes, knives, broadaxes, and possibly plows. They saw the Medfield mills as an opportunity to expand their business into hay and manure pitchforks, shovels, spades, and hoes for area farmers who, at the time, produced more than 1,000 tons of hay annually and looked after hundreds of head of livestock. Partridge's operation prospered for twenty years during which time he built a large cut-granite mill building.

For a brief time after the Civil War, new owners used this mill building for a paper cutting enterprise, but it quickly fell into disuse with the advent of coal-powered industry. When the town decided to widen Main Street in 1927, the mill building was dismantled and the granite reused in the construction of a house on Foundry Street. Much of the mill site now sits under Route 109. All that remains is its broad earthen dam and stone raceway at the southern end of the Reservation.

Conservation and Stewardship

Management Planning for Our Properties

Since 1891, The Trustees of Reservations have worked to protect special places in Massachusetts and maintain them to the highest standards. To ensure these standards are met, a program of careful planning and sound management is essential. Comprehensive property management plans are created for each reservation and are completely updated approximately every ten years. We often work with volunteers, property users, and members of the community to carry out this planning, which typically involves several steps:

  • Describing in detail the site’s natural, scenic, and historical resources; identifying management issues related to the protection of those resources. 

  • Describing how visitors use the property; outlining the opportunities that the property provides for people to become involved in the work of conservation and caring for their community.

  • Developing a detailed list of management recommendations, a work plan, and a description of financial needs for implementing the actions.

  • Developing a prescribed routine management program for the reservation that will guide staff work plans, volunteer involvement, and the allocation of human and financial resources.

Maps and Resources

Printed trail maps are distributed free from bulletin boards in Rocky Woods parking area. Please understand that supplies periodically run out. We recommend that you download a trail map before your visit.
