As a result, in 1787, Congress passed “An Ordinance for the Government of the Territory of the United States, North-West of the River Ohio” which established the manner in which this area would be measured, divided and then distributed.
Hutchens devised a system where the government lands were to be divided into townships of six miles square. The townships were stacked in north-to-south columns called “ranges.” Each township was itself divided into thirty-six numbered sections of one square mile each, and those were in turn divided into half, quarter and quarter-quarter sections, the smallest units being 40 square acres.
This system was eventually extended throughout the Northwest Territory, and then later to most of the lands of the Louisiana Purchase, Mexican cession, and Oregon Territory, explaining why so many roads, towns, farms, and other properties west of the Ohio and Mississippi River are so regular and straight-sided.
The first area that Hutchens surveyed was called the “Seven Ranges,” that is, the first seven stacks of townships, each six miles wide and lying between the Geographer’s Line and the Ohio River, running from the Point of Beginning forty-two miles to the west. Hutchens set off on September 30, 1785, but the survey team did not make it very far before they heard of Indian troubles no too far west, and so decided to high-tail it back to Pittsburgh. Hutchens and the surveyors were later able to secure military protection and so returned to finish the job, completing the Seven Ranges in 1787.
“Plat of the Seven Ranges of Townships being Part of the Territory of the United Sates N.W. of the River Ohio Which by a late act of Congress are directed to be sold. That part which is divided into sections or tracts of a mile square will be sold in small tracts at public auction in Pitsburg [sic] the residue will be sold in quarters of Townships at the seat of Government.”Hutchens’ system, now known as the Public Land Survey System, is still in use today, all surveys working off of the initial Seven Ranges survey of the late eighteenth century. It is this national survey grid which allowed for the orderly division and distribution of land to farmers and settlers, railroad companies, prospectors and all the other Americans who emigrated from the east to the west as the country expanded. Thus Hutchens’ “Point of Beginning” for this first survey, was in fact the Point of Beginning for all the American West.W. Barker sculp.
