Funded by the Neighborhood Friends
Fortunately, donations from the Neighborhood Friends of Mount Vernon covered the entire cost of this project.
Washington spent most of his adult life searching for a fertilizer that would invigorate his lackluster soil at Mount Vernon.
Nothing seemed to work as well as a mixture of manure and plant material that he allowed to brew together in a simple structure strategically located next to his stables.
When constructed around 1787, Washington's stercorary, more commonly known as his dung repository, was in all likelihood the first building in America devoted to composting.
Zealous gardeners across America today are incredibly devoted to their compost piles, and often prefer this rich and fragrant fertilizer to the chemical-based solutions sold in most stores.
In Washington's day, when all the choices were natural ones, the value of compost was still being questioned and evaluated. Like a scientist in a laboratory, Washington experimented with a wide range of formulas, at one point even emptying his privies to collect human waste. In an effort to include every form of natural waste, the design for the stercorary includes perches for birds inside the building so that their waste will be added to the mixture below.
Although the repository structure Washington designed and built was a simple one, the process of recreating the building was a tedious, four-year project.
Archaeologists uncovered the original cobblestone floor and identified the location of the foundation walls. Washington's original drawings for the building, if he bothered to make them, have not survived. However, it is likely that he adopted the basic form outlined in a popular Philadelphia design book of the period.
Mount Vernon craftsmen used handmade brick similar to Washington's in size and color to rebuild the foundation, and old-growth oak and locust logs were hand-sawn with period style tools to create the wood frame. The shingles, just like Washington's were cut from two centuries-old cypress.
The last ingredients--donations to the project from Mount Vernon's farm animals--are still being collected, to be joined with grass clippings collected from the estate's lawns.
