bibliography of papers and reports on these 

 investigations which have appeared in various 

 journals during the year. 



The report of the president gives detailed 

 figures showing the funds available for ex- 

 penditure during the year and the manner in 

 which these funds have been distributed. A 

 summary of these financial statements shows 

 that of the $694,094.11 available, $467,500 

 have been applied to the maintenance of large 

 projects and established departments of work; 

 $49,969.32 have been distributed in the form 

 of minor grants to individuals; $30,575.02 

 have been allotted to research associates and 

 assistants; $54,645.27 have been expended in 

 the work of publication and $49,792.21 have 

 been required for administrative purposes. 

 These allotments reached a total of $652,- 

 481.82, leaving an unallotted balance of $41,- 

 612.29 at the close of the fiscal year. The 

 total amount of funds appropriated for ex- 

 penditure from the foundation of the institu- 

 tion to the present time is $4,320,140.00, of 

 which $307,227.03 were reverted and after- 

 wards reappropriated. The total amount ex- 

 pended to date is $4,128,697.11. 



The scope of the work undertaken by the 

 institution has broadened until, as shown by 

 the present report, investigations have been 

 carried on in more than thirty different 

 fields of research and extended into more 

 than forty different countries. Two astronom- 

 ical observatories and five laboratories are 

 maintained, and the equipment of the various 

 establishments located in different parts of 

 the United States includes 58 buildings, a 

 specially designed ship and 8 smaller craft. 



The building designed for the principal 

 of&ces of the institution has been completed 

 during the past year and has been occupied 

 by the administrative staff since the second 

 week in November. It is located at the corner 

 of Sixteenth and P Streets, in Washington, 

 and contains, in addition to the executive 

 offices, an assembly room with a seating ca- 

 pacity of 200 and ample space for the storage 

 of publications. The annual meetings of the 

 board of trustees will be held here, as well as 

 the monthly meetings of the executive com- 

 mittee of the institution. 



The building was dedicated on December 

 13, when addresses were delivered by Mr. An- 

 drew Carnegie, founder of the institution and 

 Hon. Elihu Eoot, chairman of the building 

 committee. On this occasion also an illus- 

 trated lecture was given by Dr. George E. 

 Hale, director of the Solar Observatory lo- 

 cated on Mount Wilson, California, inaugu- 

 rating a series of lectures which it is pro- 

 posed to give annually. From December 15 

 to 17 the building was open to the public for 

 inspection, and exhibits from the investiga- 

 tions of the ten departments of research, to- 

 gether with the work of publication and ad- 

 ministration, were placed on view. 



As a notable event of the past year the 

 president cites the establishment and active 

 operation of the observatory of the Depart- 

 ment of Meridian Astrometry, at San Luis, in 

 Argentina, under the direction of Professor 

 Lewis Boss. The work of observation of the 

 southern stars was begun in April last, and is 

 now proceeding at a rate heretofore unequaled 

 in this branch of astronomy. Observations 

 made with the meridian-circle, transferred 

 with great care to San Luis from the Dudley 

 Observatory, in Albany, New York, will be 

 combined with corresponding observations 

 made at Albany. 



Another event of prime importance during 

 the year has been the completion and the 

 initial cruise of the nonmagnetic ship Car- 

 negie, now making a magnetic survey of the 

 Atlantic Ocean, under the direction of the 

 department of terrestrial magnetism. This 

 ship was launched on June 12, 1909, and set 

 sail upon her first voyage on August 21 last. 

 During her voyage across the Atlantic errors 

 of prime importance to navigation were found 

 in the best magnetic charts now used by 

 mariners. 



At the Solar Observatory in California the 

 60-inch equatorial reflecting telescope has been 

 tested and found highly satisfactory. The 

 construction of a new tower telescope, 150 

 feet high above ground and 75 feet below 

 ground, has been begun. In addition to the 

 further interpretation of the nature of sun- 

 spots, it is expected that an investigation of 

 the electro-magnetic properties shown by the
