276 CARNEGIE INSTITUTION OF WASHINGTON. 



The cooperation of the Department with the Government astronomer of South Australia 

 was continued during the year. Mr. A. L. Kennedy, chief assistant at the observatory, 

 made special magnetic observations during the total solar eclipse of September 21 at the 

 C. I. W. station Cordillo Downs in South Australia, and while en route to and from the 

 eclipse station, obtained secular-variation observations at ten C. I. W. stations northeast of 

 Lake Eyre. 



Absolute observations, as well as continuous photographic registrations, were made 

 throughout the year at the Watheroo Magnetic Observatory (see p. 277). 



4. Europe. — Dr. Dike in June made a series of observations at the C. I. W. station 

 Rumeli Hissar near Robert College, Constantinople, and reoccupied early in July C. I. W. 

 stations in Greece and on the island of Crete. Returning to Constantinople the first part 

 of September, he completed his field work by observations at Rumeli Hissar. 



Magnetician W. C. Parkinson, while en route to Washington from the Watheroo Magnetic 

 Observatory, from March 30 to the latter part of September, secured an extensive series 

 of observatory intercomparisons of standards at the following observatories: Ebro, near 

 Tortosa, Spain; San Fernando, near Cadiz, Spain; Coimbra Observatory, Portugal; com- 

 parison of standard instruments of the Italian Survey at Terracina, Italy; Val Joyeux, near 

 Paris, France, Potsdam, Germany; De Bilt, Holland; Rude Skov, Denmark; Sodankyla, 

 Finland; Greenwich, England; Uccle, Belgium; Eskdalemuir, Scotland; and Kew, England. 

 (The expenses on account of the work at Uccle were paid by the Section of Terrestrial 

 Magnetism and Electricity of the International Union of Geodesy and Geophysics.) During 

 September Mr. Parkinson also obtained comparisons at Teddington between his magneto- 

 meter and the Schuster-Smith magnetometer. Between April 30 and May 11, 1922, Mr. 

 Parkinson assisted the Director at the Meeting of the International Union of Geodesy and 

 Geophysics at Rome. 



5. North America. — Observers J. W. Green and W. A. Love reoccupied during June 

 magnetic stations at Waycross, Georgia, and Miami, Florida, while en route to the Bahamas 

 and West Indies. 



The MacMillan Baffin Land Expedition, with which the Department cooperated (see p. 327 

 of last annual report), returned to Wiscasset, Maine, on September 12 after an absence of 

 almost 14 months. In addition to the successful observatory work done at the winter- 

 quarters at Bowdoin Harbor (see p. 278), 28 magnetic field-stations were established, as follows 

 by Messrs. G. D. Howell, of the Expedition staff, and R. H. Goddard, of the Department 

 staff: Baffin Land, 21 (chiefly along the southern and southwestern coasts and at 2 points 

 on the northern coast) ; Labrador, 5 ; Newfoundland and Nova Scotia, one each. Four 

 of these stations were occupied also a second time during the course of the Expedition. 



Plans for further cooperation with Captain Amundsen's "Maud Expedition" were made, 

 and instrumental equipment and miscellaneous appurtenances were provided. The 

 expedition left Seattle on June 3 and Nome on June 29, for the expected drift across the 

 Polar Sea. Magnetic observations were made in July at Deering, Alaska. 



6. South America. — Upon the conclusion of his work in the West Indies, Mr. J. W. Green 

 reoccupied the C. I. W. station at Caracas, Venezuela, and then proceeded upon an expe- 

 dition westward to the Colombian boundary and eastward along the Caribbean coast, 

 occupying stations at intervals, before taking up a more extended program of work in Brazil, 

 Argentina, and other South American countries. 



Mr. W. A. Love proceeded from the West Indies to South America, where he reoccupied 

 stations chiefly in Colombia, Ecuador, and Peru. Upon the completion of this work it is 

 expected that he will take up the reoccupation of C. I. W. stations in Central America. 



Absolute magnetic observations, as well as continuous photographic registrations, have 

 been obtained since March 1, 1922, at the Huancayo Magnetic Observatory (see p. 277). 



7. Islands, Atlantic Ocean. — Observer H. R. Grummann made observations at 9 

 stations on the island of St. Thomas, St. Croix, St. Kitts, Antigua, Guadeloupe, Dominica, 

 St. Lucia, and Martinique. 



Observer J. W. Green, accompanied by Observer W. A. Love, reoccupied old stations 

 and established new ones at 12 points on the Bahama Islands. On August 9 the party left 

 Nassau and arrived at Havana, August 12, where they reoccupied C. I. W. stations Havana 

 and Pinar del Rio. Mr. Green then proceeded to Haiti and Dominican Republic, where he 

 established about 11 stations at the principal ports and accessible inland points; en route 

 he reoccupied the C. I. W. station at Kingston, Jamaica. During late August to October, 

 Mr. Love worked independently in Cuba and Jamaica, occupying 12 stations, most of 

 which had been previously occupied by observers of the Department.
