Preemption Line
From Wikipedia, the free encyclopedia
The Preemption Line (also spelled Pre-Emption) divides the Indian lands of western New York State awarded to New York from those awarded to Commonwealth of Massachusetts by the Treaty of Hartford of 1786. It was defined as the meridian (north-south) line from the eighty-second milestone of the Pennsylvania - New York survey line at 76° 57' 58" W northward to Lake Ontario.

[edit] Origin and Definition
By coincidence, The Preemption Line is near the meridian of the Capitol at Washington (77° 00' 33" W of Greenwich), but the popular assumption that the Preemption Line was intended to be on that meridian seems to be a myth, since the District of Columbia had not been surveyed at the time of the 1786 treaty; in fact Andrew Ellicott surveyed the District of Columbia in 1791-1792 and then re-surveyed the Preemption line in 1792 (see below).
The word "preemption" refers to the pre-emptive right that Massachusetts received to negotiate with the Indians -- pre-empting New York State, and also to the pre-emptive rights of the two state governments with respect to individuals, who were forbidden to negotiate directly with the Indians without first securing a patent from the respective legislature.
It is bounded on the east (New York portion) by:
- the townships of Galen and Julius of the Central New York Military Tract north of Seneca Lake;
- the Watkins and Flint Purchase south of the township of Reading in Schuyler County;
- In between a narrow strip of land eastward to Seneca Lake purchased by James Watson.
It is bounded on the west (Massachusetts portion) by the Phelps and Gorham Purchase.
[edit] The Old and New Preemption Lines
An interesting point is that there are two pre-emption lines: the Old and New (to the east of the Old); the area between is called the Gore (referring to a dressmaker's term for a wedge-shaped piece). This is because very soon after the original survey of 1788 it was suspected that this survey was in error, so a resurvey was commissioned in 1792. It showed that the first surveyors had used defective methods (or as some allege but has never been proven, fraudulent methods) so that the line, although beginning at the correct Pennsylvania boundary stone, was deflected about 2° west of north, hence the wedge shape (increasing in width to the north). It is not a simple error, however; once the survey was about two miles west of the correct line it then ran closer to true north. The original error was in favour of New York, which issued titles in the Gore; most notably, the current city of Geneva was incorrectly assigned. The new survey was accepted, as it was performed with a high-precision German transit by Andrew Ellicott, considered the best surveyor in the USA, who had just surveyed the District of Columbia.
The magnitude of the error can be appreciated at Geneva: the true (new) line is at about the midpoint of Seneca Lake at the Seneca - Ontario County boundary, whereas the false (old) line is the present-day Pre-emption Road, which forms the western limits of the City of Geneva, about two miles west.

Both begin at the same point: the eighty-second milestone of the Pennsylvania - New York survey line, located on Widget Hill Road near Millerton, PA at 76° 57' 58" W 42° 00' 03" N.
[edit] Old Preemption Line
There is no trace of this line south of Schuyler County, probably because no settlement took place in this area prior to the resurvey. In Schuyler County it forms the west line of the town of Reading, for most of this length along Pre-emption Road. It continues as the short north-south portion of the boundary between Schuyler (west) and Yates Counties along this road, and then divides the Yates County towns of Barrington (west) and Starkey (east) to their tri-point with the town of Milo, where the road also ends. A portion of road through Milo Center to the Keuka Lake outlet is on the line. It is marked again in Ontario County by the Pre-emption Road through the towns of Geneva and Phelps; this road makes some local deviations from the line. The Pre-emption Road continues a short distance into Wayne County as far as the new Erie Canal; it is not marked farther north.
[edit] New Preemption Line
This line forms the boundary between Chemung (east) and Steuben (west) Counties as well as a small north-south portion of the border between Chemung (east) and Schuyler (west) Counties at the former's northwest corner near Beaver Dams. It then forms the line between the towns of Orange (west) and Montour (east) in Schuyler County; the only roads that follows the line in this section are at the very beginning north a few miles on Widget Hill Road, and a mile of Locust Lane in Sugar Hill State Forest.
The line has no trace in Yates County; it runs north-south through Seneca Lake from a point north of Dresden.
It next appears at the north end of Seneca Lake and forms the boundary between Seneca (east) and Ontario (west) Counties to the tri-point with Wayne County; in this section it forms Pre-emption Road and most of West Town Line Road.
In Wayne County it continues north as the line between the towns of Lyons and Sodus (west) and Galen, Rose and Huron (east); by happy co-incidence it runs directly through the centre of Sodus Bay. Small sections of roads follow this line.
