Book Overview

"Terrestrial Magnetism: Magnetic Declination In The United States For January 1, 1920" offers a detailed snapshot of the Earth's magnetic field across the United States at the beginning of the 1920s. Compiled by the U.S. Coast and Geodetic Survey under the direction of Daniel Lyman Hazard, this work provides precise measurements of magnetic declination, a crucial factor for navigation, surveying, and various scientific applications.

This report serves as an essential resource for historians of science, geophysicists, and anyone interested in the historical study of geomagnetism and its applications during a transformative period in American history. The meticulous data presented reflects the state of scientific knowledge and surveying techniques of the time, offering valuable insights into early 20th-century scientific practices. Its enduring value lies in its contribution to understanding long-term changes in Earth's magnetic field and its relevance to contemporary geophysical research.
