Ca. 190 surveys, 1846-1860, primarily of land and property in Concord, Mass. (including three of Walden Pond). Collection also includes surveys of land in Acton, Bedford, Boxborough, Carlisle, Framingham, Haverhill, Lincoln, Littleton, and Stow, one well-known survey of the Concord River "from East Sudbury to Billerica Mills," and one of Eagleswood in Perth Amboy, N.J. (done for Marcus Spring). (Cont.) Surveys include properties belonging to A. Bronson Alcott, Edward Carver Damon, Ralph Waldo Emerson, Francis R. Gourgas, Nathaniel Hawthorne, Edward S. Hoar, Samuel Hoar, Edmund Hosmer, John Hosmer, David Loring, the Concord Mill Dam Company, Abel Moore and John Brooks Moore, William Munroe, Daniel Shattuck, Samuel Staples, Cyrus Stow, the Town of Concord, and others. The sizes and dimensions of the surveys vary considerably, the largest being the rolled river survey (38 x 233 cm.). Some of the surveys in the collection are pencil drafts, some finished products in ink. Thoreau's volume of field notes and other ms. calculations and notes he made in preparing the surveys (also included in the Library's Henry David Thoreau Papers) shed additional light on individual items in the survey collection. Although not strictly a survey, Thoreau's "Statistics of the Bridges Over Concord River, Between Heard's Bridge and Billerica Dam ..." is included in the collection, as are several traced or copied maps.
