RESURVEYS 



Object of resurveys. Owing to poor 

 marking of lines and the rapid oblitera- 

 tion of corners, numerous surveys are 

 required to determine the location of 

 original corners. Such work comes 

 under the head of resurveys. The sole 

 object of a resurvey is to locate and find 

 the original corner. The law and the 

 supreme court decisions are explicit on 

 Post which tk* s P om t> "that in a resurvey the origi- 

 served as n al corner must be located if possible. 

 ner thirty- It is not a question of where the corner 

 should be, but of where it actually was 

 placed. Even though gross errors may have 

 occurred in the original work, the old corner, if 

 found, must be accepted as correct. In a resur- 

 vey the complete record of the original survey 

 should be obtained, and the regulations govern- 



the scctiott COY- 



ing at that time should be taken into considera- ner shown in 

 tion. Then as many corners as practicable Flg ' I04 

 should be found, and, with these to work from, the original 

 survey should oe duplicated. After the approximate location 

 of the corner has been determined by careful measurement,
