REPORT OF iSTATIONAL, MUSEUM, 1921. 129 



thereby bringing the work up to date and making it possible to 

 catalogue the accessions as received in the future. This was a large 

 amount of work and took several months to accomplish it. The 

 completion of the card catalogue almost marks an epoch in the records 

 of the collection. Up to this year the card catalogue consisted of 

 three separate sj'stems, from which no totals could be obtained. The 

 numbers now run in an unbroken series, the last entry being 3388, 

 and a cross- reference is partially completed. 



The wall cases on the south side of the court were cleaned and 

 material in them stored. This space was used for the Bradj^ Civil 

 War and Signal Corps' photographs of the Great World War. This 

 collection of pictures complements the war collections made by the 

 Museum and attracts much attention from visitors. 



The series of partly finished lenses furnished by Bausch & Lomb 

 Optical Co. makes a fine new exhibit and will be of interest to those 

 who wish to learn how a fine anastigmat lens is made. There are 

 many and various processes of fine workmanship which enter into 

 their manufacture. 



In order to place new and timely exhibits, old ones must be taken 

 down. This crowded condition and lack of space somewhat inter- 

 feres with the growth of the collection and the desire to secure new 

 material. Mr. G. S. Williams, of Washington, is a friend of the 

 collection. In the past he has secured many exhibits and always 

 has the advancement of the collection in mind. Likewise Mr. George 

 Harris, of Harris & Ewing, sends material of Museum interest, that 

 comes to him in the course of business. 



Mr. C. L. Lewis, Toledo, Ohio, past president of the Photogra- 

 phers' Association of America, often visits the collection when in 

 Washington, and was instrumental in securing the transparency and 

 lantern slide of the McDonough color process received during the 

 year. The collections of the section are unique. The Photogra- 

 phers' Association of America has appointed a committee to form 

 a similar collection, to be at Winona Lake, Ind., where they aim 

 to establish a school of photography, endowed by the association. 

 The formation of another collection will make competition for new 

 material, and funds should be provided so the section of photography 

 can purchase rare specimens when they come on the market. 



Plans for the coming year are a continuance of those formulated 

 last year. A section devoted to the history of color photography . 

 and motion pictures is in course of development. Efforts will be 

 made to secure recent pictorial photographs from America's leading 

 pictorial workers.
