Magnetic Inspection Trip 207 



a photographer, for development and taking prints. On the 4th the steamer Tofua arrived 

 from the Tongas, having aboard the various eclipse parties, among others the Australian 

 astronomers, who reported having had more or less unfavorable conditions during the eclipse. 

 As far as could be ascertained, my own party at Manua Island had been favored with the 

 best weather. 



I left Apia, May 8, on the steamer Alua, bound for Auckland. On the 10th we arrived 

 at Vavau, of the Tongas, the scene of great activity just a few days previous, owing to the 

 advent of the many astronomers who had selected this station as the most favorable and 

 most accessible point. The next morning (May 11) we arrived at Hapaii, where we took 

 aboard Mr. and Mrs. Clement Wragge, who had observed the eclipse in this vicinity. They 

 reported having had more favorable conditions than had been experienced by the English 

 and the Australian parties at "S'avau. Mrs. Wragge had made a drawing of the corona 

 which agreed well with a similar sketch made by Captain Holford, of the Tofua, which I 

 had seen at Apia. 



I must not fail at this point to express my obligation to Commander (now Captain) 

 Crose, U. S. N., at the time Governor of Tutuila, Samoa, for the very substantial aid 

 rendered in promptly putting at my disposal the Annapolis and her personnel. Not only 

 was I conveyed on the Annapolis, with my entire instrumental outfit, to the observation 

 station on Manua Island, but there was also put at my disposal services without which the 

 desired end could not have been attained. Particular mention should be made of the 

 zealous and effective cooperation received from Commanding Officer Lieutenant McDowell, 

 Executive Officer Lieutenant Baker, Captain Steffany of the Altair, Mr. Reed, as assistant 

 photographer, and Quartermaster Urle, as magnetic recorder. Chaplain Pierce and Doctor 

 Connor also assisted in various ways. 



It is likewise a pleasant duty to speak of the cordial assistance rendered by the Samoans 

 of Manua; reference has already been made to the whole-hearted hospitality and uniform 

 courtesy shown by them, especially by Queen Vaitupu, in whose house the party had the 

 pri\ilege of living, and by the various chiefs, who arranged for our entertainment. The 

 remembrance of the happy days spent amidst these very friendly people will be a never- 

 ending source of pleasure. 



So, likewise, the numerous courtesies shown me at Apia by the German Governor, Dr. 

 Erich Schultz, and his various officials, as also by Dr. Hammer, of the Geophysical Observa- 

 tory, and by the .American consul, Mr. Mason Mitchell, deserve grateful acknowledgment. 

 And last, but not least, must be mentioned the effective aid rendered by Mr. Abbot in 

 supplying the apparatus and the requisite instructions for the photographic work. 



MAGNETIC OBSERVATIONS ON APRIL 28, 1911. 



According to special arrangement, magnetic observations simultaneous with ours at 

 Tau were made at the five magnetic observatories of the L^nited States Coast and Geodetic 

 Survey, also at Melbourne, Christchurch, and Apia, where quick-run magnetograms were 

 obtained for five hours. Until the records have been received from stations over the entire 

 globe, it will not be possible to determine definitely whether or not the present eclipse was 

 accompanied by any minute and temporary change in the Earth's magnetism. It is 

 proposed to devote a future monograph to this special subject and there bring together all 

 the magnetic results obtained during recent eclipses. 



MAGNETIC INSPECTION TRIP. 



Having completed some magnetic observations at the Geophysical Observatory, I 

 left Apia, May 8, visiting en route to Colombo the magnetic observatories at Christchurch, 

 New Zealand, and Melbourne, Australia. At Melbourne I also concluded arrangements for 

 cooperative magnetic work in Australasia and with the Australasian Antarctic Expedition.
