230a. The Unit of land measure is the acre.
Measurements of land are commonly recorded in square miles, acres, and hundredths of an acre. The ordinary table of land measure with examples will be found on pp. 173 to 177.
230b. Government Lands are usually surveyed into rectangular tracts, bounded by lines conforming to the cardinal points of the compass.
A Base Line on a parallel of latitude, and a Principal Meridian intersecting it, are first established. Other lines are then run six miles apart, each way, as nearly as possible.
The tracts thus formed are called Townships, and contain nearly 23040 acres. A line of townships extending north and south is called a Range.
The ranges are designated by their number east or west of the principal meridian. The townships in each range are designated by their number north or south of the base line.
Since the earth's surface is convex, the principal meridians converge as they proceed northward. This tends to throw the townships and sections out of square, and necessitates occasional lines of offset, called "correction lines."
Townships are subdivided into Sections, and sections into Half-Sections, Quarter-Sections, Half-QuarterSections, Quarter-Quarter-Sections, and Lots.
