The manor house dates from c.1855 and was remodeled in 1871 by George R. Dykeman.","why_significant":"The nomination argues the property is significant for its role in local agricultural history, as a trout hatchery and later a creamery that helped shift the Cumberland Valley toward dairy farming. It also cites Dykeman's association with the founding of the Cumberland Valley State Normal School, the Italianate remodeling of the manor house, and the potential for archeological information.","narrative":"Dykeman's Spring is a group of springs near Shippensburg, Cumberland County, with a brick manor house, a stone hatch house and two spring-fed ponds. A brick farmhouse was built on the site by Edward Scull in 1855. George R. Dykeman bought the property in 1870 with Stephenson and converted it into a trout hatchery, enlarging the pond and building the hatch house in 1871. In that year he doubled the farmhouse and remodeled it in the Italianate style, adding a hip roof with a cupola, arched porch, cast iron window hoods and paired brackets. The hatch house later served as a creamery into the 1940s. Dykeman's operations are credited with encouraging dairy farming across the valley. He also helped found the Cumberland Valley State Normal School and engineered the early water system for the town. The property is also significant for two recorded prehistoric sites and its potential for historic archeology.","period_of_significance":"c. 1855 - 1948","architect_builder":"George R.
