40 ANNUAL REPORT SMITHSONIAN INSTITUTION, 19 31 



MISCELLANEOUS 



The exhibition halls of the National Museum were open during 

 the year on week days from 9 a. m. to 4.30 p. m., except that the Air- 

 craft Building, as has been noted, was closed for repairs for eight 

 months during the year. Our Museum halls were also open on Sun- 

 day afternoons from 1.30 p. m. to 4.30 p. m., with the exception of 

 the Aircraft Building. All buildings remained closed during the 

 day on Christmas and on New Year's. 



The flags on the Smithsonian and Museum Buildings were placed 

 at half mast from 1.15 p. m. April 9 through April 11, out of respect 

 for the late Speaker of the House of Representatives, the Hon. Nicho- 

 las Longworth. During the forenoon of Memorial Day the flags 

 also were held at half-mast. Visitors for the year totaled 1,669,140, 

 a decrease of a little more than 230,000 from the record of the pre- 

 ceding year, this difference being due partly to the fact that the Air- 

 craft Building was closed for a considerable part of this period. 

 Attendance in the several buildings in the National Museum was 

 recorded as follows: Smithsonian Institution, 258,616; Arts and In- 

 dustries Building, 731,186; Natural Histoiy Building, 631,498; Air- 

 craft Building, 47,840. The average daily attendance for week days 

 was 4,452, and for Sundays 5,472. 



During the year the Museum published 7 volumes and 41 separate 

 papers, while the distribution of literature amounted to 86,680 copies 

 of its various books and pamphlets. Additions to the Museum 

 library, obtained partly by exchange, partly by donation, and partly 

 by purchase, included 2,528 volumes and 832 pamphlets, an increase 

 over those of the previous year. The library of the National Museum, 

 as separate from that of the Smithsonian Institution proper, now 

 contains 79,407 volumes and 109,129 pamphlets. Much progress was 

 made during the year in the arrangement and cataloguing of these 

 collections, not only in the main libraries but also in the 36 sectional 

 libraries of the organization. Duplicate volumes in our series have 

 been assembled and many have been distributed to other organiza- 

 tions, either as gifts or as exchanges. 



On March 5, 1931, John E. Graf was appointed associate director 

 of the National Museum under the assistant secretary. Mr. Graf 

 came to the Museum by transfer from the Department of Agricul- 

 ture, where he had long been connected with the administration of 

 the Bureau of Entomology, in recent years as assistant chief. 



In the department of anthropology the former divisions of Ameri- 

 can archeology and of Old World archeology were consolidated on 

 February 1, 1930, as a division of archeology, under Neil M. Judd 

 as curator.
