Magnetic Inspection Trip 209 



was hold tlie I'ollowing day with Professor Fuson regarding magnetic work in China. The 

 Portuguese station at Macao and the various sites for magnetic work there were examined 

 on November 9. November 13 to 15, I visited at Manila the sub-office of the Coast and 

 Geodetic Survey, the Manila Meteorological Observatory (Reverend Jose Mgue, director); 

 also, in company with Reverend Saderra Maso, I went to the new magnetic observatory 

 at Antipolo. 



On concluding the necessary arrangements at Manila respecting the Carnegie's visit 

 to this port, I had accomplished the main purposes of my inspection trip. However, on my 

 return journej' to Washington, I also visited the following observatories: Zikawei (Novem- 

 ber 20), Tsingtau (November 22), Tokio (November 27), Honolulu (December 7), Mount 

 Wilson (December 15-16), Tucson, Arizona (December 18). I arrived in Washington on 

 December 24, having been absent 9 months, the total distance traveled approximating 

 47,000 miles. Besides the eclipse work and the inspection trip on the Carnegie, 18 magnetic 

 observatories were visited, and some comparisons were secured at 3 of them; various other 

 representative scientific institutions interested in terrestrial magnetism, atmospheric elec- 

 tricity, and allied topics were also paid visits. I wish to express here my grateful appreci- 

 ation of the courtesies everyw^here received and the special efforts made by those in charge 

 to familiarize me with the work of their respective institutions. 



It had been mj* original intention to retuin to Washington via Siberia, and to visit 

 magnetic institutions en route from Tokio, but circumstances made necessary an alteration 

 of plans. However, during a two months' trip to Europe in the spring of 1913, I was 

 enabled to visit, besides other institutions, the following additional magnetic observatories: 

 Potsdam and Seddin (May 6), Rude Skov, near Copenhagen (Mav 16), and Greenwich 

 (May 29). 



I now have, by personal visits, made myself accjuainted with 28 of the existing magnetic 

 observatories, and 6 of the remaining number, about 17, have been visited by other repre- 

 sentatives of the Department. In this way the Department of Terrestrial Magnetism has 

 been enabled to come into pleasant relations and enter into effective cooperation with the 

 existing magnetic services the world over.
