VIII. THE PERIOD FROM 191 1 TO 1920 



From the founding of the Association in 1848 until the year 1909 the 

 Proceedings of its meetings were published in annual volumes. For many 

 years the Proceedings contained all papers in full for which manuscripts 

 were supplied to the permanent secretary. As the number of papers in- 

 creased it became necessary to reduce reports of them to abstracts, except 

 the addresses of retiring presidents. Beginning with 1908 the addresses of 

 retiring presidents have been published in Science and have not been in- 

 cluded in the Proceedings. Since 19 10 both preliminary announcements and 

 reports of the meetings have been published in Science, and copies of the 

 issues of Science containing the reports have been sent to every member of 

 the Association. 



With the publication in Science of the addresses of the retiring presi- 

 dents of the Association and of most of the vice presidents, and also of many 

 other papers presented at the meetings, the importance of the Proceedings 

 as a medium for the publication of addresses and papers declined. There- 

 after the reports of the programs of the meetings were given only in con- 

 densed form. For example, the Proceedings for 1885, containing a report 

 of the only (Philadelphia) meeting held that year, amounted to 736 pages; 

 while the Proceedings for 1908 and 1909, including condensed reports of 

 three meetings, namely, a special summer meeting in Hanover, N. H., in 

 1908, the annual meeting held in Baltimore, Dec, 1908 - Jan., 1909, and also 

 the meeting held in Boston, in December, 1909, totaled only 686 pages. 



As a consequence of these various factors, beginning with 1912 the Pro- 

 ceedings have been published only in summarized form, each volume cover- 

 ing a period of several years. The second Summarized Proceedings were 

 published in 1915, the third in 1921, the fourth in 1925, the fifth in 1929, 

 and the sixth in 1934. 



In 191 5 the Pacific Division of the Association was organized and held 

 its first annual meeting at San Diego, Calif,, in August. 1916. The South- 

 western Division was organized in 1920,
