DID YOU KNOW ……?
That to correctly survey a 40 acre tract such as the NW ¼¼ of the SE ¼¼ (fig. 1) requires a survey of almost the entire section? Consider the steps that are necessary:
a. Recover original government corners 1, 2, 4, 6 & 8.
b. Establish the center of the section (point A) which is the intersection of a straight line between points 4 & 8 and 6 & 2.
c. Establish 1/16^{th} corners B, C, D & E (point B is exactly midway between points A & 2, etc.).
d. Establish SE 1/16^{th} corner (point F) which is the intersection of straight lines between points B & D and C & E.
e. Analyze the above against existing monuments found at or near computed locations.
The above steps are necessary to locate the four corners of (in this case) the NW ¼¼ of the SE ¼¼. Since most sections have dimensions such as in figure 2 (exaggerated to show that the lines are not straight or parallel, due to difficulties in the original surveys done in the 1850's) it follows that the distances around a 40 acre tract as shown will not always be 1320' or at right angles to each other.
