In other words, break your problem down into a series of smaller
problems, working from all known corners to find or restore any
lost corners. At this point, we'll mention again that a thorough
search should be made for all intervening corners along the line
between control corners already located.
If nothing is found the first corners to be restored should be
the section corners. Then, the quarter corners using single-proportion
as stated in Section
5-38 of the manual.
Another important point, if you haven't retraced enough of an original
survey to indicate that there might be more then one search area,
you should do it.
The section corner thought to be lost could be found in the search
areas indicated, because the original surveyor chained short or
long on the north/south line.
