Sheard, Levi, Mill
Also known as: Clymer, John S., Mill
Why it's listed
Beside the Tohickon Creek on Covered Bridge Road in East Rockhill Township, Bucks County, stands a three-story stone mill whose first section dates to about 1825. Built of randomly laid fieldstone with a milled timber frame, it grew through additions around 1850, about 1870 and about 1905, the last housing a cider press. A millrace and stone-lined forebay feed water to the building, and its interior still holds much of its historic machinery, including a flour dresser, scourers, a hammermill and drive belts. The mill is regarded as an excellent example of mill architecture and has an important role in local milling history. It ground grain and produced feed until the late 1960s, and in 1917 new Robinson Manufacturing equipment was installed. Its records also show a later contract to sell Purina feed. Its surviving machinery and building fabric document the shift from water-powered milling to commercial feed production.
Significance in brief: The nomination argues the mill is significant for its role in the local milling industry, operating as a gristmill from about 1825 until the late 1960s and later as a feed mill. It is also presented as an excellent example of mill architecture, with its original machinery largely intact and its plain Georgian-style features reflecting its function.

What listing means for this property
For an income-producing building, listing (individually or as a contributing building in a district) is the gateway to the 20% federal rehabilitation tax credit on qualified rehabilitation costs, often stackable with state credits. Work claiming the credit must follow the Secretary of the Interior's Standards and be approved in advance.
Listing does not restrict a private owner acting without federal money or permits; where federal funding or licensing is involved, Section 106 review applies.
