That line is not present on this map. Large uncolored cartouche in lower right depicting Indians and White traders. The boundaries of Virginia and Carolina do not resemble today's, but those of Maryland and New Jersey are recognizable. Philadelphia is neatly laid out north of the 40th parallel and several miles inland from the Delaware River. That supposed location north of the 40th parallel became a source of considerable friction when it became obvious Philadelphia was inside Maryland's original 40th parallel grant.
New Jersey appears as two parts, East New Jersey and West New Jersey.
In the southwest is a giant Apalache Lake draining into the May River. Florida extends to the Great Lakes.
