The National Park Service is indebted to all those persons who made the production of this book possible. The text greatly benefited from suggestions by naval architect and historian John G. Arrison and historian Frederick R. Black. The primary source for the yard history was the National Park Service report, _The Charlestown Navy Yard 1800-1973_ (_1800-1842_ by Edwin C. Bearss; _1842-1890_ by Edwin C. Bearss and Frederick R. Black; _1890-1973_ by Frederick R. Black). Other important sources were Kenneth J. Hagan’s _This People’s Navy: The Making of American Sea Power_, 1991; Howard I. Chapelle’s _The History of the American Sailing Navy_, 1949; and Donald L. Canney’s _The Old Steam Navy_, 1990. The handbook was produced by the staff of the Division of Publications, National Park Service: Susan Barkus, designer; William Gordon, editor; Nancy Morbeck Haack, cartographer, assisted by the staff of Boston National Historical Park. _All photos not credited are from the files of Boston National Historical Park._ Mary Altier 84 (bottom left) John Batchelor 24-25, 26-27, 40-41, 42-43, 58-59, 60, 74-75 _Battles and Leaders of the Civil War_ 43 (top) Boston Athenaeum 4-5, 30, 32-33 The Bostonian Society/Old State House 10-11, 46 George Eastman House 23 Louis Glanzman 19 Greg Harlin 21 (right) James Higgins 66 (top), 78-79, 82-83, 84 (bottom right), 85, 86 (top, bottom) _The Kedge-Anchor_, by William N.

This includes fostering the wisest use of our land and water resources, protecting our fish and wildlife, preserving the environmental and cultural values of our national parks and historical places, and providing for the enjoyment of life through outdoor recreation. The Department assesses our energy and mineral resources to ensure that their development is in the best interest of all our people. The Department also has a major responsibility for American Indian reservation communities and for people who live in island territories under U.S. administration.
