REPORT OF THE SECRETARY. 45 



The work of the Congressional Joint Commission on Reclassifica- 

 tion of Salaries created great activity among the civil employees of 

 the Government in Washington, and the Museum afforded a meeting 

 place for the scientific-technical section of the Federal Employees' 

 Union No. 2, to complete the organization of the section, for a sym- 

 posium on the principles involved in fixing salaries, and for ad- 

 dresses by Prof. Irving Fisher on the purchasing power of salaries 

 and by Drs. McClung and Howe on the work of the National Re- 

 search Council; for the Smithsonian branch of the Federal Em- 

 ployees' Union No. 2, and for various other groups of civil employees 

 for organizing, preparing data, and otherwise helping toward the 

 classification of the Government forces in Washington, including 

 Federal workers interested in bookkeeping, accounting, and auditing, 

 the clerical force of the Department of Agriculture, the Federal 

 photographers, the marine and stationary operating engineers, the 

 subcommittee on personnel of the reclassification committee, and 

 members of the Museum's scientific staff. 



MISCELLANEOUS. 



Under the auspices of the Arts Club of Washington, a special ex- 

 hibition of illustrations of the famous bell towers of the world was 

 held in rooms 46 and 47 of the Natural History Building from Oc- 

 tober 2 to 31, inclusive. The Arts Club has undertaken to enlist the 

 cooperation of all lovers of freedom in furthering a plan to erect at 

 the Nation's Capital a national peace tower with the largest and finest 

 carillon that the most expert bell founders of the world can provide, 

 as a tribute to the heroic resistance of Belgium, in recollection of our 

 dead and those of our allies, and in enduring commemoration of the 

 great victory won over imperialism. 



An exhibition of drawings, photographs, and paintings illustrating 

 the activities of the Air Service of the United States Army at the 

 front and in America was opened to the public from October 4 to 

 October 29, 1919, in the west north range, ground floor. Natural His- 

 tory Building. Capt. Otho Cushing was in charge of the exhibit. 



The Museum library was increased by 1,932 bound volumes and 

 1,581 pamphlets, mainly obtained by gift and exchange, bringing the 

 total in the library up to 56,617 volumes and 88,690 pamphlets and 

 unbound papers. While there were no exceptional pieces contributed, 

 there was a collection of special importance — the personal library of 

 Dr. Charles D, Walcott. His intimate association with the paleon- 

 tological collections of the Museum makes the Museum sectional 

 libraries of vertebrate and invertebrate paleontology difficult of dup- 

 lication. 



The publications of the Museum for the year consisted of the An- 

 nual Report for 1919; volumes 54, 55, and 56 of the Proceedings;
