REPORT OF THE PRESIDENT OF THE INSTITUTION. 



In compliance with the provisions of Article IV of the By-L,aws of the 

 Carnegie Institution of Washington, I have the honor to submit the fol- 

 lowing report on the work of the Institution for the fiscal 

 Introductory State- year ending October 3 1 , 1906, along with recommendations 

 of appropriations for the following year, and with sundry 

 suggestions concerning pending and prospective questions presented by the 

 development of the Institution. 



The year just ended has been one of great activity in all of the principal 

 branches of work carried on under the auspices of the Institution. This 

 is especially the case with all of the larger departments of work, which, in 

 spite of the fact that they are only fairly started, are already producing 

 noteworthy results. 



The mode of administration of the work of the Institution, explained in 

 my report of the preceding year, has been followed essentially during the 

 past year, and hence needs no additional explanation here. 



The research as distinguished from the administrational activities of the 

 Institution may be classified roughly under the four following heads, which 

 are the same as those used in my preceding report, namely : 



1. lyarge projects carried on under the direct auspices of the Institution 

 by departments having corps of investigators. 



2. Minor projects carried on by individuals temporarily affiliated with the 

 Institution. 



3. Work of research associates and assistants. 



4. Work of publication. 



This classification may serve to indicate the lines of division for the details 

 of subsequent parts of this report. 



The following table shows the unallotted balances brought forward from 



appropriations of previous years ; the amounts appropriated for the year by 



the Board of Trustees at their meeting of December 



^7S:^Y^l"mtmt 12, 1905 ; the revertments during the year ; the totals 



available for expenditure during the year; and the 



unallotted balances at the end of the year for large grants, minor grants, 



research associates, publication, and administration, respectively. To con-
