THE AMERICAN ASSOCIATION FOR 

 THE ADVANCEMENT OF SCIENCE 



REPORT OF THE SECRETARY OF THE COM- 

 MITTEE ON GRANTS FOR RESEARCH 



To the Executive Committee of the Council, 



American Association for the Advancement 



of Science. 

 Gentlejnen : 



In accordance with youi' request I submit the 

 following report of the Committee on Grants 

 for Research, this being a summary of the 

 activities of the committee during the Ave years 

 since its organization. 



By the settlement of the Colburn estate in 

 1916 the association received cash and securi- 

 ties valued at about $76,000, bequeathed by 

 Richard T. Colburn, a fellow of the associa- 

 tion, the income of which is to be devoted "to 

 original research in the physical and psychic 

 demonstrable sciences." The association had 

 accumulated a fund of about $25,000, mainly 

 from the fees of fellows, life membei-s, and 

 membere. The income from these funds being 

 available for grants for research, the sum of 

 $4,000 was, at the New York meeting of the 

 association, on the recommendation of the 

 treasurer, set aside for this purpose by the 

 council, to be expended during the year 1917. 



At the same time a Committee on Grants for 

 Research was appointed, consisting of seven 

 members under the chairmanship of Edward C. 

 Pickering. These members, as well as their 

 successors, were chosen so as to represent as 

 far as possible the different sections of the 

 association. At the meeting of the association 

 in December, 1918, the committee was enlarged 

 to include nine members, while a year latei', 

 with the adoption of the new constitution of the 

 association, the number was changed to eight, 

 the term of each member to be four years, with 

 the arrangement of rotation so that two mem- 

 bers should be succeeded by new appointees
