Because of the fact that the surveying of public lands over the years has 

 not been carried out in a continuously systematic manner, there are many 

 duplications in the numbering of townships and ranges. Therefore, in addition 

 to the township and range, the state and, in some instances, the county, must 

 also be known before a location on the map can be made. For this reason, the 

 state and county should be given in the location of a well.
