This article examines the value added to the United States Lighthouse Service by the operator's manuals, which were issued to the lighthouse keepers by the Light-House Board in 1852. Subsequent reports of the board to Congress conclusively show that the manuals resulted in a significant savings in the operating costs of the service. In addition, annual reports of district superintendents show that the instructional information improved the appearance and reliability of the lights. Furthermore, the manuals helped to reduce significantly the number of marine disasters along America's shores in the years following the board's decision.
