the size of a township and section in the land ordinance
Land Ordinance of 1785 The 1785 ordinance laid the foundations of land policy until passage of the Homestead Act in 1862. The Land Ordinance established the basis for the Public Land Survey System. The initial surveying was performed by Thomas Hutchins. After he died in 1789, responsibility for surveying was transferred to the Surveyor General. Land was to be systematically surveyed into square townships, six miles (9.656 km) on a side. Each of these townships were sub-divided into thirty-six sections of one square mile (2.59 km²) or 640 acres. These sections could then be further subdivided for re-sale by settlers and land speculators.[4]
