Procedure at the magnetic observatories of the Carnegie Institution of Washington

Abstract

The magnetic observatory established by the Department of Terrestrial Magnetism of the Carnegie Institution of Washington, near Watheroo, Western Australia, to be known as the “Watheroo Magnetic Observatory,” has been in operation since January 1, 1919. The observatory buildings were constructed and the instruments were installed under the direction of an experienced magnetician, Mr. W. F. Wallis, for many years in charge of various magnetic observatories of the United States Coast and Geodetic Survey. After three years' strenuous work, Mr. Wallis returns to Washington to assume duties at the laboratory of the Department of Terrestrial Magnetism. In November, 1919, Mr. Edward Kidson, at one time an assistant at the Christchurch Magnetic Observatory and for many years observer in the Department of Terrestrial Magnetism, both on land and sea duty, assumed charge of the Watheroo Magnetic Observatory.
