The rectangular survey system ... sets up what is known as "initial points," a position which is determined by accurate field astronomical methods. From these ... points, lines known as principal meridians and base lines are extended. The principal meridian line runs north and south conforming to the true meridian and extending from the initial point or monument. Regular township corners are established at intervals of 480 chains ([[distance::6 miles]]) along this line.

Due to the curvature of the earth, it is necessary to make corrections in the parallels and meridians... This is accomplished ... usually at intervals [of] 24 miles east and west of the principal meridians. This method produces the rectangular sections of [[area::640 acres]] each, with the sections along the north and west boundaries of the township absorbing the deficiency or excess in the measurements and convergence.

Using a 360 degree compass, shown in Figure 3,... the plot of the above metes and bounds property description use[s] the following procedure:

# Place the center of the compass at the point of beginning of the line of course, designated as Point A in Figure 4a, with the north and south line of the compass coinciding with the line selected to be the north and south line of the map. [Editor's note: A ''course'' is the combination of the direction and length of any particular line, such as "north 40° east, 200 ft."]
