WORK OF ADMINISTRATION. 



The more noteworthy events in the history of the Institution during the 

 past year are the dedication in December, 1909, of the Administration Build- 

 ing; the inauguration at that time of an annual series of 

 Salieot Events of the semi-popular lectures explanatory of the researches of the 

 Institution; the inauguration on the same occasion of a 

 series of periodical exhibits of the work accomplisht by the departments of 

 investigation and the divisions of publication and administration; the suc- 

 cessful completion of the first voyage (of 8,000 miles) of the non-magnetic 

 ship Carnegie, and the beginning of a second cruise, which is expected to 

 require three years, by this novel craft; and the fourth conference of the 

 International Solar Union held at the Solar Observatory of the Institution 

 on Mount Wilson, California, from August 29 to September 4, 1910. 



The administrativ staff of the Institution movd into the Administration 

 Building on November 8, 1909 ; and altho the building was not then com- 

 pleted and equipt in all its parts, it was so far advanced in the two upper 

 stories as to permit immediate use and a formal dedication on the evening of 

 Monday, December 11, 1909. On this occasion the Trustees and their guests 

 assembled in the lecture room of the building and brief addresses were made 

 by the Chairman and Vice-Chairman of the Board of Trustees and by the 

 Founder of the Institution. Following these ceremonies a lecture on the 

 work of the Solar Observatory was given by Prof. George E. Hale, Director 

 of that establishment. The Trustees and their guests were then invited to 

 inspect the exhibits instald in the rooms of the uppermost floor of the Admin- 

 istration Building by the ten principal departments of research of the Insti- 

 tution and by the divisions of publication and administration.
