LECTURES. 



Hamilton fund lecture.— "Th.^ Hamilton fund was placed under the 

 administration of the Institution by the Rev. James Hamilton in 

 1875, the interest to be used for "lectures on scientific or useful sub- 

 jects." Under the auspices of this fund an interesting lecture was 

 delivered on April 13 in the auditorium of the National Museum by 

 the Rev. Charles E. Jefferson, D. D., on "The old order and the 

 new," in which Dr. Jefferson gave his views as to the causes which 

 led the world into its present unsettled condition and of the solution 

 of the problems presented. 



Lectures for the Y. M. G. A. — At the request of Dr. W. C. Little, 

 field secretary of the Young Men's Christian Association, a series of 

 lectures on scientific subjects written in a style to be instructive and 

 entertaining to a general audience was prepared by members of the 

 staffs of the Institution and its branches, for use in the educational 

 extension work of the association. The scheme was to have these 

 lectures delivered in rotation by volunteer lecturers in many different 

 localities in the United States, thereby reaching a large number of 

 people interested in keeping in touch with the advance of science 

 and progress in general. The lectures prepared by members of the 

 Smithsonian staff were as follows:

CINCHONA BOTANICAL STATION. 



In my report last year it was stated that negotiations had been 

 begun with the Government of Jamaica to renew the Smithsonian's 

 three-year lease on the Cinchona botanical station which was can- 

 celed during the period of the war. This was successfully arranged 

 in January, 1920, and the renewed lease dated from January 1.
