This says he only laid the 1st stone..................


Ellicott's team, minus Banneker, who left after the placement of the south stone, then began the formal survey by clearing twenty feet of land on both sides of each boundary and placing other stones, made of Aquia Creek sandstone, at one-mile intervals. On each stone, the side facing the District of Columbia displayed the inscription "Jurisdiction of the United States" and a mile number. The opposite side said either "Virginia" or "Maryland," as appropriate. The third and fourth sides displayed the year in which the stone was placed (1791 for the 14 Virginia stones and 1792 for the 26 Maryland stones) and the magnetic compass variance at that place. Stones along the northwest Maryland boundary also displayed the number of miles they fell from NW4, the first stone placed in Maryland. Stones placed at intervals of more than a mile included that extra distance measured in poles.

The boundary stones are the oldest federal monuments. Although several boundary stones have been moved or severely damaged, thirty-six stones from the 1790s and one substitute stone (SW2) are in or near their original locations, including all fourteen in the land that was returned to Virginia in the 1846-1847 retrocession. Two (SE4 and substitute SE8) are in storage and another (NE1) is marked by a plaque. This site describes the locations of the stones as of 2015, updating the information provided by the Daughters of the American Revolution (1976) and the National Register of Historic Places (1996).
