magnetism. He was also a delegate to the International Solar 

 Research Conference meeting in St. I^ouis, September 22. 



The director has also been appointed a member of a committee of 

 the International Association of Academies, which is considering 

 methods for securing increased accuracy in magnetic work at sea. 



PIEI.D WORK. 



Nothing further could thus far be' attempted under this head than 

 to place orders, as authorized, for instruments required in future 

 work, study various designs, train certain of the employees in field 

 work with the aid of the facilities furnished and instruments loaned 

 by the Superintendent of the Coast and Geodetic Survey, and to test 

 some recently arrived instruments. Preparations are being made for 

 international cooperation in magnetic and allied observations during 

 the solar eclipse of August 29-30, 1905, and a circular has been 

 issued inviting the cooperation of all those who can take part in this 

 important work. 



Plans for systematic magnetic surveys of the oceanic areas have 

 been carefully considered. One magnetic outfit required for such 

 work has been received from the maker, and the constants of the 

 instrument have been determined. Also a feasible plan for a rapid, 

 systematic magnetic surv'ey of the North Pacific Ocean has been 

 worked out, in collaboration with Mr. G. W. Littlehales, hydro- 

 graphic engineer of the U- S. Hydrographic Office, and with the 

 advice of Captain E. W. Creak, formerly Superintendent of the 

 Compass Department of the British Admiralty, now retired, and of 

 O. H. Tittmann, Superintendent of the U. S. Coast and Geodetic 

 Survey. This project is published in full elsewhere.
