Almost as soon as the Deed was signed, disputes arose over the exact dividing point of the two provinces. The first attempt at resolving the issue, the Keith line, was created by Surveyor-General George Keith in 1686, and runs North-Northwest from the southern part of Little Egg Harbor, passing just north of Tuckerton, and reaching upward to a point on the Delaware River which is just north of the Delaware Water Gap. More accurate surveys and maps were made to further resolve property disputes. This resulted in the Thornton line, drawn around 1696, and the Lawrence line, drawn around 1743, which was adopted as the final line for legal purposes.
