206 REPORTS ON INVESTIGATIONS AND PROJECTS. 



two widely separated crossings, and across the tracks of the principal steam- 

 ship lines, thence back to Colombo, and from there to Batavia. Intercom- 

 parisons of the sea and land instruments, as well as valuable intercomparisons 

 of the standards of the Department and those of the Royal Meteorological 

 and Magnetic Observatory, were secured at Batavia. At the end of the fiscal 

 year these intercomparisons were still under way. The Director again met 

 the vessel at Batavia to give final instructions for the continuation of her 

 cruise under Mr. Peters's command. 



At each port of call the party has received most cordial assistance. In 

 particular may be mentioned Mr. Hartnell, observer-in-charge of the U. S. 

 Coast and Geodetic Survey Magnetic Observatory at Vieques, Porto Rico ; 

 Dr. H. Morize, director of the Observatorio Nacional, and Capt. Radler de 

 Aquino, at Rio de Janeiro ; Dr. Walter G. Davis, director of the Meteoro- 

 logical Service of the Argentine Republic, and his various assistants at the 

 observatory at Pilar ; the government officials of the Department of Agri- 

 culture of the Argentine Republic ; Drs. Beattie and Dodds, of Cape Town ; 

 Dr. Hough, director of the Royal Observatory, Cape of Good Hope ; Dr. 

 Barnard, assistant surveyor-general of Ceylon, and his assistant, Mr. Bam- 

 ford, in charge of the observatory at Colombo ; Mr. A. Walter, director of 

 the Royal Alfred Observatory at Mauritius; and Dr. W. van Bemmeln at 

 Batavia. The various official representatives of the United States Govern- 

 ment have also been of invaluable assistance at the various ports of call, and 

 have greatly facilitated the work. 



Atmospheric electricity observations have been conducted on board the 

 Carnegie, as opportunity afforded, by Messrs. Kidson and Johnston, Mag- 

 netic Observers. Atmospheric-pressure observations have been carried out 

 and various improvements in the method of observations effected. Obser- 

 vations for atmospheric-refraction effects at sea have also been made, as 

 was possible during the cruise. 



The personnel of the Carnegie during the year has been as follows : 



Scientific staff: L. A. Bauer, Director ; W. J. Peters, commander ; C. C. Craft, surgeon 

 and magnetic observer to April 1911; H. M. W. Edmonds, surgeon and magnetician 

 from March 191 1; E. Kidson, magnetic observer to June 191 1; H. D. Frary, mag- 

 netic observer; H. F. Johnson, magnetic observer from March 191 1; C. R. Carroll, 

 meteorological observer and clerk to September 1911. 



Sailing staff: F. S. McMurray, first viratch officer; M. Clausen, second vk^atch officer; 

 A. Jorgensen, third watch officer to January 1911; E. W. Jansson, third watch

 engineer since April 191 1 ; i mechanic, 8 seamen, 2 cooks, 2 cabin boys. 



OFFICE WORK. 



The manuscript giving the magnetic results obtained in the land observa- 

 tions since the inauguration of the work of the Department and through 

 December 31, 1910, and for the land stations occupied by the Galilee and the 

 Carnegie parties through April 191 1 will be completed, it is expected, in time 

 to turn over to the printer at the end of the calendar year. The manuscript
