made the expedition possible. The Director, on return from the eclipse trip 

 in May, made magnetic observations at Pago Pago, Tutuila, and at the mag- 

 netic observatory at Apia, Samoa. 



South America. — Magnetic Observer C. C. Stewart has continued his work 

 in South America. The progress of this work was somewhat retarded by 

 the unfortunate destruction by fire of the launch El Imdn while in port at 

 Iquitos, Peru, on January 15. It proving impracticable to replace the launch, 

 he then continued the work with the aid of such local means of travel as 

 were found available. He occupied twenty-two stations in Peru and Brazil 

 and completed the line of magnetic survey for practically the whole length 

 of the Amazon. Besides establishing several secular variation stations, he 

 tied up his work with that of the Carnegie at Pinheiro. Mr. Stewart re- 

 turned to the Office in September and is at present recuperating from fever 

 contracted in the course of the work. 



Miscellaneous. — In connection with the operations of the Carnegie, land 

 stations have been established at Pinheiro (near Para) and Rio de Janeiro, 

 Brazil ; at Pilar, Cordoba, where intercomparisons were obtained with the 

 standards of the magnetic observatory of the Argentine Republic; at Cape 

 Town, South Africa ; at Colombo, Ceylon ; at Port Louis, Mauritius, where 

 intercomparisons were obtained with the magnetic standards of the Royal 

 Alfred Observatory ; and at Buitenzorg, Batavia, Java, where the Carnegie's 

 instruments were compared with the standards of the Royal Meteorological 

 and Magnetic Observatory. 



INSPECTION WORK. 



The Director left Washington on March 16 in order to make a trip of 

 inspection of the land and ocean work and to confer with the heads of vari- 

 ous magnetic organizations in Australasia and Asia respecting continuation 

 or inauguration of magnetic surveys under their charge. He left Vancouver, 

 British Columbia, on March 24, going via Hawaii and Fiji to Samoa, where 

 he obtained eclipse magnetic observations at Tau Island. He made magnetic 

 observations at Pago Pago and Apia, as elsewhere stated, and proceeded 

 thence to Auckland, New Zealand ; Christchurch, New Zealand, and Sydney 

 and Melbourne, Australia, visiting the magnetic observatories at Christ- 

 church and Melbourne. x\t Sydney and at Melbourne he met the members 

 of the committee having charge of the scientific work of the Australasian 

 Antarctic Expedition, under the leadership of Dr. Douglas Mawson, and 

 made the necessary arrangements with them regarding cooperation of the 

 Department with the expedition in proposed magnetic-survey work in the 

 Antarctic. From Melbourne he went to Adelaide, thence to Fremantle and 

 Perth, and then directly to Colombo, Ceylon, arriving there June 21. At 

 the various places visited in Australia the interest of local organizations was 

 enlisted and arrangements were perfected for the inauguration of a magnetic 

 survey of Australia (one of the largest land areas remaining to be explored 

 from this standpoint) under the joint auspices of the Department and of
