Second, the 1901 surveyor ran west between Sections 20 and 29 and
established the quarter corner at 40, but did not complete that
In 1912, the east half mile was retraced. The original quarter
corner was found in good condition and the west half mile was surveyed.
Then, a 1960 retracement of the 1912 work finds no remaining evidence
of the quarter corner of Sections 20 and 29. That quarter corner
should be reestablished using irregular exterior adjustments.
When making this adjustment we must assume that the retracement
was made using record courses and distances.
If the present retracement is not run according to record courses,
the record courses must still be computed on paper and the amounts
of correction must still be applied to the record courses.
