REPORT OF THE PRESIDENT OF THE 

 CARNEGIE INSTITUTION} 



In compliance with the provisions of 

 article IV. of the by-laws of the Carnegie 

 Institution of Washington, I have the 

 honor to submit the following report on 

 the work of the institution during the fiscal 

 year ending October 31, 1905, along with 

 recommendations of appropriations for 

 work during the succeeding year, and with 

 some suggestions concerning the future 

 course and progress of the institution. 



Coming as the writer has to the presi- 

 dency of an institution already well organ- 

 ized, but still in the earlier stages of its 

 development, it is essential for the purposes 

 of a report to assume as a point of de- 

 parture the plan and scope of operations 

 found well under way. Accordingly, the 

 resume of the work of the year given below 

 is an account of work planned substan- 

 tially by the executive committee of the 

 preceding year. Similarly, the recom- 

 mendations made with respect to the ensu- 

 ing year are mainly in accord with the 

 lines of policy hitherto followed by the 

 executive committee. The additional ex- 

 perience of this year seems to confirm, espe- 

 cially, the wisdom of concentrating the 

 resources of the institution on a small num- 

 ber of large projects rather than on a large 

 number of small projects. Concerning this
