Adam Hoops was hired to lead a team of new surveyors, who discovered that Maxwell erred on both the eastern preemption line and the western boundary. Maxwell had located the westernmost boundary of the Millyard Tract in the belief that the Genesee River ran due north. Hoops' team found that Maxwell had made a serious error when he ignored the variance between magnetic north and true north. A survey team that Benjamin Ellicott headed found in November–December 1792 that the preemption line ran through Seneca Lake and north along a line to Lake Ontario near the center of Sodus Bay, about four miles west of the line surveyed by Maxwell. The line now divides the city of Geneva and the Town of Waterloo in Border City. The old preemption line reached Lake Ontario, three miles west of Sodus Bay. The new line terminated near the center of the head of the bay. The new preemption line traveled in a northeasterly direction from the west end of the southern boundary.
