REPORT OP THE SECRETARY 27 



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. and on Sundays from 

 1.30 p. m. to 4.30 p. m., with the exception of the Aircraft Building, 

 which was open only on week days. All buildings remained closed 

 during the day on Christmas and on New Year's. 



Visitors for the year totaled 1,630,030, a decrease of 39,110 from 

 the record of the preceding year, this difference being due partly to 

 the fact that the Aircraft Building was closed on Sundays. Attend- 

 ance in the several buildings was recorded as follows: Smithsonian 

 Institution, 241,844; Arts and Industries Building, 675,435; Natural 

 History Building, 600,535 ; Aircraft Building, 112,216. The average 

 daily attendance for week days was 4,237 and for Sunday 5,927. 



During the year the Museum published 10 volumes and 57 separate 

 papers, while the distribution of volumes and separates to libraries 

 and individuals aggregated 101,975 copies. In addition, 18,805 copies 

 of publications issued during this and previous years were supplied 

 in response to special requests.
