168 Ocean Magnetic Observations, 1905-16 



from Suva was delayed by contrary winds blowing through the narrow entrance. A course 

 was steered along the parallel 30° south, passing between the outward and homeward- 

 bound passages of the Galilee's last cruise. From near Easter Island a northerly course 

 was followed to the equator; thence the course was westerly, and then southwest to Tahiti. 

 On crossing the equator, the ship was swung under favorable conditions for magnetic incli- 

 nation and intensity. The observations, made on the various headings in the two observing 

 domes, again showed smaller differences among themselves than the general accuracy of 

 sea observations. 



Papeete, the port of Tahiti, was reached September 11, 1912; here the actmg governor 

 and other officials took great interest in the Carnegie and her work. On October 15, 

 after completion of the land work, the vessel sailed for Coronel, Chile, where she arrived on 

 November 25. The magnetic station estabhshed at this place in 1907 by the Explorer, of 

 the United States Coast and Geodetic Survey, was reoccupied. After the necessary land 

 observations had been made for the determination of constants and intercomparisons of 

 instruments, the Carnegie proceeded to Talcahuano on December 4. At this port, through 

 the courtesy of the Chilean naval officials, particularly Admiral Francisco Neff , the govern- 

 ment dry-dock was used for dry-docking the vessel and carrying out necessary repairs. 

 While at Talcahuano opportunity was given Observers Hewlett and Johnston to visit Dr. 

 Walter Knoche, in charge of the meteorological work for the Chilean Government at 

 Santiago, and to discuss with him methods of work in atmospheric electricity at sea. 

 Subsequently Dr. Knoche visited the Carnegie at Talcahuano and kindly made some 

 further suggestions. 



Leaving Talcahuano December 19, 1912, the Carnegie proceeded next to Stanley, 

 Falkland Islands, arriving there January 27, 1913. A northwest course was foUowed to 

 about 26° south latitude and 95° west longitude, thence southwest to about 40° south 

 latitude and 107° west longitude, and thence around Cape Horn to Stanley. Winds of 

 great strength prevailing for days at this port, considerable delay was experienced in the 

 completion of the work, which included a reoccupation of the magnetic station given in the 

 "British Admkalty List." Dr. Edmonds was relieved of ocean duty at Stanley in order 

 to take charge of a land expedition to Hudson Bay, and Dr. C. C. Craft was assigned as 

 surgeon and magnetic observer in his place. Acknowledgments are due the Governor of 

 the Falklands, Honorable W. L. AUerdyce, and other officials and persons at Stanley for 

 numerous kindnesses shown. -, tt i r n • 



The Carnegie sailed from Stanley on February 22, 1913, bound for St. Helena, following 

 a great-circle route to 46?5 south latitude and 1° east longitude. Along this portion of the 

 passage a number of large icebergs were seen. The 191 1 track of the Carnegie was crossed, 

 as well as that of the Gauss while on her Antarctic cruise. The Carnegie was swung at sea 

 on March 21, and it was once more found that the magnetic observations (magnetic inclina- 

 tion and intensity), made on the various headings, agreed with each other within the 

 observational errors. Arriving at Jamestown, St. Helena, on April 3, the stop made this 

 time was only long enough to provision the vessel, attend to the accumulated correspondence, 

 and dispatch the observation records to Washington. In order to make the more southerly 

 return passage from Bahia to St. Helena before the Sun reached the summer solstice as 

 had been planned, the usual shore work was postponed, and St. Helena was left on April 9, 

 the course being set direct for BaWa. En route, observations of the magnetic declination 

 were made during a complete swing of the vessel, confirming the absence of possible devia- 

 tions greater than the error of observation. 



Bahia was reached on April 24. As the Brazilian station at Bahia was no longer 

 suitable for secular- variation purposes, a new magnetic station was established on Jaburu 

 Point (PI. 19, Fig. 2) where intercomparisons were made ashore of all instruments used
