Two general evening sessions of popular 

 interest, were held. At one of these was 

 given an illustrated lecture by Dr. E. F. 

 Griggs, on the region of Mt. Katmai, Alaska, 

 and the "Valley of Ten Thousand Smokes." 

 The other general interest lecture was by Pro- 

 fessor R. W. Wood, on high power fluores- 

 cence and phosphorescence, in connection with 

 which he performed numerous very ingenious 

 experiments and demonstrations dealing with 

 the study of these phenomena and of ultra- 

 violet light. 



The opening session, Monday evening, and 

 the two general interest sessions were held 

 in Mandel Hall. Attendance on these three 

 evenings was as follows: 



Several new or unusual features character- 

 ized this meeting. The visible directory of 

 those registering, kept currently corrected by 

 several typists and attendants, proved very 

 valuable. The pianels bearing the directory 

 slips were hung along one side of the registra- 



tion room, the north room on the first floor of 

 Resmolds Club. 



The increase of scientiflc knowledge and 

 interest among the general public is one of 

 the most important functions of the asso- 

 ciation and the one which it has been most 

 difficult to accomplish. The reports in the 

 press vary from year to year, and at Chicago 

 represented a fair average. Several of the 

 more important papers, such as that of Pro- 

 fessor Michelson on the application of inter- 

 ference methods to astronomical measure- 

 ments, were fully report, not only in Chicago 

 but also in ITew York and other cities. The 

 Science Service definitely organized at Chi- 

 cago for the wide-spread diffusion of current 

 scientific information will hereafter make pos- 

 sible adequate reports of scientific meetings. 



The minutes of the proceedings of the 

 Council, and reports of sections and affiliated 

 societies will be printed in later issues of 

 Science. Among the matters of general in- 

 terest transacted at the meetings of the 

 Council are the following: 



It was decided that the nest meeting of the 

 Ajnerican Association will be at Toronto, on 

 Tuesday, December 27 to Saturday, December 

 31, 1921, inclusive. The opening session will 

 be on Tuesday evening. The meeting for 

 1922-1923 will be held in Boston, and that 

 for 1923-24 will be held in Cincinnati. Then 

 will follow the stated convocation meeting in 

 Washington. 



Dr. Burton E. Livingston was reelected 

 permanent secretary and Dr. E. S. Woodward 

 was reelected treasurer, each for a term of 

 four years. Dr. L. O. Howard and Professor 

 Herbert Osbom were elected members of the 

 executive committee. 



The Academies of Science of Michigan and 

 of Oklahoma were affiliated with the asso- 

 ciation. 



The collection of portraits and autograph 

 letters of all presidents of the association 

 made by Dr. Marcus Benjamin of the Smith- 

 sonian Institution will be purchased under 

 conditions representing a partial gift to the 

 association. 



The sum of $5,000 was appropriated for
