In the late 18th century, astronomer Charles Mason and surveyor Jeremiah Dixon established the border line between Pennsylvania and Maryland with astonishing accuracy in order to settle a boundary dispute. They placed stones (imported from England) every mile and crownstones every 5 miles.
On Wednesday, Oct. 20, Todd Babcock, chairman of the Mason and Dixon Line Preservation Partnership, will be discussing this remarkable feat in a lecture at Primitive Hall in West Marlborough. Tickets are $35 and include a reception before the talk. For more information visit the Hall's website, http://www.primitivehall.org/.
