The western boundary of Pennsylvania was established in William Penn's 1681 charter, and was dependent upon the longitude of the eastern bound… In August 1764, they ran a line from the New Castle Court House to determine the correct tangent point. Both sides agreed that Pennsylvania's grant made its western border a tracing of the course of the Delaware River, displaced five degrees (approximately 265 miles) to the west.

[19][29][30] Several years later Cavendish used a very sensitive torsion balance to carry out the Cavendish experiment and determine the average density of Earth. Negotiations ensued after the problem was discovered in 1681. [19] There was keen interest in their work and much communication between the surveyors, Maskelyne and other members of the British Scientific establishment in the Royal Society in Britain, notably Henry Cavendish. [citation needed], Later, the line was marked in places by additional benchmarks and survey markers. [citation needed], The line was established to end a boundary dispute between the British colonies of Maryland and Pennsylvania/Delaware. This usage especially came to prominence during the debate around the Missouri Compromise of 1820, when drawing boundaries between slave and free territory was an issue.

It also included the western border of present-day Delaware, as it was then a part of the Pennsylvania colony. The project took nearly 5 years, and the new border was marked by large blocks of limestone, some weighing as much as 600 pounds.
