318 CARNEGIE INSTITUTION OF WASHINGTON. 



journey, via the Caqueta and Putamayo Rivers, through the south- 

 eastern part of Colombia, into Brazil, and thence on the Amazon River 

 to Manaos, arriving there on September 24. With the completion of 

 Mr. Power's expedition, the general magnetic survey of South America 

 north of the Amazon is almost concluded. Mr, Power returned to 

 Washington on October 17. 



Observer H. R. Schmitt left Washington on March 6 for magnetic- 

 survey work in Peru, Bolivia, Chile, and Brazil. En route to Lima 

 he reoccupied our station at Kingston, Jamaica. Having occupied the 

 repeat stations at Lima, Callao, and Mollendo, Peru, he entered Chile 

 at Arica, and proceeded thence by rail to La Paz, Bolivia. From La 

 Paz he successfully carried out a difficult overland expedition via 

 Cochabamba to Corumbd, Brazil, where he arrived the latter part 

 of June, having made magnetic observations, en route from Arica, 

 at 20 stations. Early in July Mr. Schmitt left Corumba bound for 

 San Luiz, and thence down the River Guapore to Guayara-merim, 

 where he arrived the middle of September. After securing observations 

 at some of the stations occupied in this neighborhood by Observer 

 Stewart in 1911, Mr. Schmitt proceeded by the Madeira River to 

 Manaos, Brazil, arriving there the middle of October. Throughout 

 the trip from Corumba to Manaos, observations were made at an 

 average distance apart of about 35 miles. 



With the successful accomplishment of the two expeditions, Mr. 

 Power's and Mr. Schmitt's, the general magnetic survey of the western 

 countries of South America is rapidly nearing completion. 



MISCELLANEOUS. 



In addition to the above land work, the observers of the Carnegie 

 established 5 stations in the vicinity of Hammerfest, Norway, as 

 also a number of stations around the harbor of Reykjavik, Iceland; 

 at the latter place marked local disturbances were found. Observa- 

 tions were also made by the Carnegie observers at Greenport and 

 vicinity, in December 1913 and October 1914. 



Throughout the year all of the observers have made, whenever 

 possible, declination observations at close intervals, and for as many 

 hours as possible, on the first and fifteenth days of each month. On 

 August 21, during the total solar eclipse, a special program of work 

 was carried out by many of the observers, at whatever station they 

 happened to be at the time, as also by Mr. Fleming at Washington. 

 Special observations were likewise made on board the Carnegie on this 

 day, she being at sea off the southeast coast of Iceland. Data have 

 also been received from a number of magnetic observatories which 

 participated in the program of international magnetic and allied obser- 

 vations during this eclipse, as proposed by the Department.
