# Old public-land surveying: instructions, field tables, and instrument references

A three-document historical research trail for interpreting how U.S. public-land surveys were performed and recorded. Combines official instructions and field calculation tables with an early instrument-maker reference. Useful for map historians, genealogy researchers, and collectors of surveying equipment.

Not a substitute for a licensed survey. #Surveying #PublicLands #HistoricMaps #LandRecords
