made after the monuments of the original survey have 

 disappeared. When disputes occur as to land lines, it is 

 advisable to attempt to adjust them by considering all of 

 the local conditions and finding actual evidence of the line 

 rather than to go into court. It is impossible to determine 

 even reasonably correctly the point of the original corner 

 after it has once been destroyed. The idea that a surveyor 

 can set up an instrument and locate a line or corner is true 

 only when he has sufficient original corners to work from.

Fig. 106. Showing the methods of setting reference stakes for relocating a 

 section corner which will be destroyed by grading. Either method can be used 

 and the stakes set at any angle. The only instrument required is a tape line. 

 Reference stakes should be driven to the surface of the the ground and located 

 at sufficient distance from the corner so that they will not be disturbed. As 

 soon as the work is completed the corner should be replaced. If the stakes are 

 carefully set, measurements are not necessary, but a measurement is a check in 

 case one of the reference stakes is lost 



Then he will probably fail to make a proper location, as 

 there may have been an error in the original survey and the 

 corner may not have been placed properly. Land boundaries 

 are located properly only when the original corners are in 

 position. Any boundary determined under any other con- 

 ditions is probably inaccurate, and it may be entirely out 

 of the question to reestablish it in its correct location. 



Preservation of corners. Landowners should take a 

 greater interest in the preservation of survey monuments 

 marking their boundaries. When grading or excavation work 

 is done, survey monuments are frequently in the way and 

 i aust be removed, but by a system of reference points a monu- 

 ment can easily be replaced on the completion of the work.
