Magnetic Work of the Galilee, 1905-08 11 



CRUISE II, MARCH TO OCTOBER 1906. 



To settle the various matters pertaining to the continuation of the work and the pro- 

 posed additional alterations in the ship and in the instruments, which were shown desirable 

 by the experience of the first cruise, the Du-ector made an inspection trip to the Galilee at 

 San Diego, December 15-18, 1905. As all the members of the scientific personnel of the 

 first cruise, excepting Observer J. P. Ault, were obhged to return to their duties with the 

 United States Coast and Geodetic Survey at the expu-ation of their furloughs, it was neces- 

 sary to reorganize the staff. W. J. Peters, who had been in charge of scientific exploring 

 parties of the United States Geological Survey in Alaska, and had been second in command 

 and m charge of the scientific work of the second Ziegler Polar Expedition (1903-1905), was 

 intrusted with the command of the Galilee for the balance of her work (1906-1908). To 

 him were assigned as assistants on the second cruise, Observers J. P. Ault and J. C. Pearson 

 (formerly instructor in physics at Bowdoin College), and Dr. H. E. Martyn, surgeon and 

 recorder. Alterations in the vessel, decided on by the Director, were made chiefly under 

 the direction of J. F. Pratt, in command of first cruise, who also rendered the new commander 

 the requisite assistance in the preparations for the second cruise. (See Plate 1, Fig. 3.) 



The alterations, harbor swings, and shore observations having been completed, the 

 Galilee left San Diego on March 2, 1906, and took a direct course for Fanning Island. A 

 stay of 10 days from March 31 to April 10 was made at this port, during which time all 

 necessary shore and swing observations were made at the stations occupied on the first 

 cruise. The next stop was made at Pago Pago, Samoan Islands, from April 26 to May 1. 

 On account of great local attraction, and from lack of tug facilities, no harbor swmgs or 

 shore observations were made at this point. At Apia, Samoan Islands, May 3 to 9, 

 comparisons were made between the Galilee instruments and those of the German Geophys- 

 ical Observatory, then in charge of Dr. Franz Linke, to whose kindness and cooperation 

 appreciative reference is made. The Apia Geophysical Observatory was originally estab- 

 lished under the auspices of the Gottingen " Konigliche Akademie der Wissenschaften" for 

 the purpose of participating in the scientific program of the British and German Antarctic 

 Expeditions of 1902-03. Later it was continued, at the solicitation of the Carnegie Insti- 

 tution of Washington, in order to furnish magnetic data desired in connection with the mag- 

 netic survey of the Pacific Ocean. Harbor swings were not made at Apia, owing to the lack 

 of sufficient tug facilities and to the strong harbor currents. 



At the next port, Suva, Fiji Islands, comparisons were made between the instruments 

 of the ship and those used by G. Heunbrod, then in the employ of the Department as a 

 temporary magnetic observer for the work on the islands of the South Pacific. Harbor 

 swings were also made at Suva on May 18 and 20. Jaluit, of the Marshall Islands, was 

 reached on June 21 and shore and harbor observations were made, inclusive of a vessel 

 swing, after which a course was made for Guam on June 30. Between July 1 1 and 24, harbor 

 swings and shore observations were made at San Luis d'Apra, Guam. Thence sail was set 

 for Yokohama, Japan, where the expedition arrived on August 13. 



At Yokohama numerous shore observations as well as harbor swings were made and, 

 through the courtesy of Dr. K. Nakamura, in charge of the Central Meteorological Observa- 

 tory of Tokio, and of Dr. A. Tanakadate, of the University of Tokio, comparisons with the 

 observatory standards of Japan were secured. To both of these gentlemen, and to their 

 assistants, grateful acknowledgment should be made. 



On August 24 the Galilee dragged her anchors in a typhoon and was blown on the break- 

 water at Yokohama, and sank in 14 feet of water; as soon as possible she was dry-docked 

 and the necessary repairs were made. Fortunately the damage was not very serious, and 

 she was enabled to take up her work again on September 6, on which date the expedition 

 left Yokohama for San Diego. Arriving at San Diego on October 19, she had thus ter- 

 minated her second cruise in the Pacific Ocean and had covered on this cruise approximately
