4.6 Report of the President 



During the year the photographer has made 4,857 prints, 

 1,760 slides, 955 negatives, 339 enlargements and 33 trans- 

 parencies, but large as these numbers are, they are no 

 indication of the labor involved in producing the results 

 desired. 



Through the faithful and efficient work of Miss Muenche- 

 hofe, the reference file of photographs grows apace. This file 

 now numbers 29,848 prints. The file of negatives numbers 

 23,881. 



It has been stated repeatedly that the Museum possesses a 

 collection of 35,000 lantern slides, but it has never been 

 possible to make the fullest use of this valuable material since 

 it is uncatalogued. A beginning has now been made on this 

 important work. A new system of filing based on the Dewey 

 Decimal System is being developed, which when completed 

 will enable one to locate quickly slides on any subject desired. 

 Nearly 2,000 slides have already been arranged in this file. 



Accessions. — The principal accessions for the year are a 

 collection of about 150 birds' skins from Miss Evelyn Purdie 

 and a collection of minerals, rocks, shells and birds' eggs from 

 Clinton G. Abbott. Gifts from Charles Bohem, Mrs. H. S. 

 Dewey, Miss Annie Miller and Arthur E. Krause have helped 

 in beautifying the Children's Room. G. Seymour Willson 

 kindly loaned us a set of negatives of gold mining in South 

 America from which prints were made. 



MINERALS 



L. P. Gratacap, Curator 



Department of Mineralogy. — The past year has seen 

 the complete installation of the minerals in the new Morgan 

 Hall. These were practically in position at the close of 191 1, 

 but considerable refinement in the installation has improved 

 their appearance. Large descriptive head labels in metallic 

 frames have been placed over the various sections throughout 

 the hall, enabling the visitor, by the simple process of their 

 consecutive inspection, to find any mineral species he is in
