Information engraved on the stones includes the number (1 through 10) of the stone within the sequence on that side of the District, the date of placement, and the words "Jurisdiction of the United States." In the twentieth century, the Daughters of the American Revolution voluntarily took responsibility for preserving the stones, which had fallen victim to vandalization and urban development. In the late 1990s renewed interest in the boundary stones led to increased preservation efforts by the DAR and other organizations.
