204 REPORTS ON INVESTIGATIONS AND PROJECTS. 



the local organizations. As elsewhere stated, Magnetic Observer Kidson 

 has been placed in charge of the Department's work. 



At Colombo the Director made an examination of the ocean results and 

 secured comparisons between the magnetic standards carried by him and 

 those of the Carnegie. From Colombo he proceeded with the Carnegie to 

 Port Louis, Mauritius Island, and thence with her on the return to Colombo, 

 inspecting the ocean work and making various tests. The party arrived the 

 second time at Colombo September lo. After supplying the commander, 

 Mr. Peters, with such additional instructions as were necessary for the con- 

 tinuation of the work, he left the party September ii, for Bombay, Dehra 

 Dun, and Calcutta, India. He arrived at Batavia on October 23 and left for 

 Hongkong, China, October 28, after having given final instructions for the 

 work of the Carnegie. At the close of the fiscal year the Director was en 

 route. 



OCEAN WORK. 



At the end of the last fiscal year the Carnegie was en route between Para 

 and Rio de Janeiro, Brazil. She arrived at the latter port on December 2, 

 1910, the voyage having been made under very favorable observing condi- 

 tions. Intercomparisons of barometer standards were carried out at the Rio 

 de Janeiro Observatory. Upon the completion of the usual harbor inter- 

 comparisons of land and ship instruments, and swing observations on De- 

 cember 23 and 24, the party sailed on December 29 for Montevideo, Uruguay, 

 and Buenos Aires, Argentine Republic. 



No land observations were made at Montevideo, at which place the Car- 

 negie arrived on January 14, whence she proceeded, after a short delay by 

 storm, to Buenos Aires, arriving there January 18, 191 1. The observing 

 conditions between Rio de Janeiro and Buenos Aires were very good and 

 numerous observations were obtained. The comparisons of ship and land 

 instruments, as well as the intercomparisons of the Argentine magnetic 

 standards and those of the Department, were carried out at the magnetic 

 observatory of the Meteorological Service of the Argentine Republic at 

 Pilar, Cordoba. Comparisons of barometer standards were also made at the 

 office of the Meteorological Service in Buenos Aires. 



The Carnegie sailed from Buenos Aires on February 14; but owing to 

 adverse winds and tidal conditions, together with the loss of an anchor, sub- 

 sequently recovered, did not get to sea from the river until the 21st. Owing 

 to this delay and to foggy weather in the vicinity of Tristan da Cunha, it 

 was found impracticable to stop at this island, as had been planned, so that 

 practically a great-circle course was followed between Buenos Aires and 

 Cape Town. This portion of the cruise was very successful and many data 

 were secured, despite the foggy conditions prevailing during a part of the 

 time. Cape Town was reached March 20. Intercomparisons of the land 

 and sea instruments, as well as comparisons between the magnetic outfits of 

 Professors J. C. Beattie and J. T. Morrison, were secured at Valkenberg,
