RULES AND PRACTICES 39 



A copy of the Chart Specifications form should accompany all "Histories" of new and 

 reconstructed charts. 



Histories of canceled charts and histories prior to reconstruction of a chart are stored in 

 the Federal Records Center, Alexandria, Va. Requests for these histories should be referred to 

 the Standards Section. 



FUTURE HISTORY RECORD 



Form C&GS-8325 entitled "Information of Value in Future Corrections to Charts" 

 should be fiUed out and filed in front of the History for the chart concerned. 



This form was designed to record information which the cartographer discovers while com- 

 piling a chart and which he wishes to pass on as a help at the time of futiu-e corrections to the 

 chart. Some of the items which should be recorded are noted on the form as a guide. The 

 cartographer should also add any information regarding a particular chart which, in his opinion, 

 should be preserved for future reference. For example, notes regarding the need for future 

 surveys, the location of certain fixed aids, or the mention of discrepancies in source material 

 which cannot be reconciled, would be very useful. Areas in which information is needed should 

 also be indicated on a set of standards in the Standards Section. 



The form should be consulted for possible assistance to the Cartographer when experiencing 

 difiBculty in applying source material.
