Land Magnetic Observations, 1914-20 



in October 1919, Cruise VI was begun. Observations at Dakar, West Africa, the first 

 port of call, were prevented by quarantine regulations then in force, and so the first 

 land observations of the cruise were made at Buenos Aires, January 19 to February 21, 

 1920. The track then lay to St. Helena; Cape Town, South Africa; Colombo, Ceylon, 

 and Fremantle, Western Australia. After a visit by the party to Watheroo Observatory 

 in September 1920 the Carnegie sailed to Port Lyttelton, New Zealand, and thence 

 to Papeete, Society Islands, where a brief stop was made, to Fanning Island, where 

 conditions prevented a landing for observations, and to San Francisco, California, where 

 she arrived in February 1921. The observers by whom the observations were made 

 are given in the list on page 21. 



The land stations occupied are listed in Table 42. In this connection, it should be 

 noted that auxiliary stations in vicinity of main stations were usually established for the 

 purpose of making instrument-comparisons, and in some cases to determine whether 

 local disturbance existed.

Observatory-Site Surveys. Many of the stations listed in the Table of Results (pp. 

 30-97) were occupied in connection with special studies of various localities with a 

 view to their possible availability as sites for the establishment of magnetic observatories. 

 These will be discussed in detail in a subsequent volume of these Researches. In 1916 

 Mr. Wilfred C. Parkinson, having completed his work in the Pacific Islands, proceeded 

 to Western Australia, where he was later joined by Mr. W. F. Wallis, who directed the 

 examination of several places. The geographic requirements specified for the location 

 were that it should be south of 28 south latitude, west of 118 east longitude, not less 

 than 50 miles from the sea, at an altitude of not more than 1,200 feet, and reasonably 

 accessible. The stations occupied in the course of the search for a suitable location are
