Some boundary lines follow permanent and obvious markings such as stone walls. Often, however there is little or no clear evidence of a boundary line. Don't automatically assume, however, that a barbed wire fence is right on the line, because that's not always the case. And never mark a line permanently until you are sure it is correctly located. To find a boundary line, the following technique is sometimes successful.
Boundary work is done more easily when leaves are off the trees.
Start at a corner that you are sure is accurate. Run a test line by taping along the appropriate bearing for the distance indicated. Temporarily mark the line as you go with plastic flagging or strips of cloth. When you reach the end of the measured distance, you should be in the vicinity of the corner you are seeking. At the end of the test line, search for evidence of the old corner.
