Mason-Dixon Survey

The northern boundary of Delaware (originally the Three Lower Counties), the celebrated Arc, related to William Penn's original land grant from Charles II. It reflected the land holdings of Charles's brother James, the Duke of York, in the region. Penn soon acquired the Three Lower Counties from James. The Three Lower Counties’ separate identity eventually resulted in the State of Delaware.

Pennsylvania (the Penns) and Maryland (the Calverts) contended over the location of the boundary they shared. The Crown intervened and demanded a survey that Mason and Dixon undertook.

A complex history of the boundaries shared by Delaware, Pennsylvania, and Maryland is simplified “In a Brief History of the Mason-Dixon Line”  by John Mackenzie. The saga of the famous survey that came to personify the division of Northern and Southern interests began and passed through the region. [“The Delaware Arc” pp. 17-18]

The Tour: Mason-Dixon Survey

I. Stargazer Stone
Mason and Dixon spent the winter of 1763 in Embreeville Pennsylvania, making astronomical observations at the John Harland farm, where they sighted on a firmly planted stone that became the Stargazer’s Stone. Nearby, the still-standing (private) Harland House sits where Embreeville and Stargazer Roads intersect.

II. Post Mark’d West
In the midst of White Clay Creek Park is an engraved granite shaft commemorating the original wooden marker that signified the beginning of the Mason-Dixon Line survey. The original marker read “Post Mark’d West,” [“Post Mark’d West” pp. 26-27]

III. The Wedge
Where Delaware, Pennsylvania, and Maryland converge is the once-curious Wedge. This disputed plot, throughout the nineteenth century, was relatively lawless, since no state exercised jurisdsiction, Wikipedia has a helpful article. [“The Wedge” pp. 20-21]

IV. The Horn
Another disputed area around the Arc, known as the Horn, lies just west of Centerville Delaware. [“The Horn” p. 23]

V. The Ticking Tomb
In Landenberg PA graveyard is a bit of folklore regarding the Mason-Dixon survey known as the Ticking Tomb. You can read about the colorful legend of an obese toddler who swallowed Mason’s special watch in Tales of the Chesepeake, “Ticking Stone” p.31. [“Ticking Tomb” pp.28-29]
