 the general collections. These slides are continually in use in our

 many slides are made are preserved and catalogued, so that they 

 can easily be duplicated. The committee is under obligations 

 to Professor William Libbey, Jr., of Princeton, for prints of his 

 Hawaiian views and of those he obtained on the Peary Relief Ex- 

 pedition to Greenland in 1894 ; to Professor I. C. Russell, of Ann 

 Arbor, for the set of views in the Malaspina District of Alaska ; to 

 Dr. C. Hart Merriam of the Department of Agriculture, Wash- 

 ington, for the privilege of copying his collection of views from 

 Death Valley, Cal. ; to Mr. F. H. Newell, of the United States 

 Geological Survey, for a similar privilege with certain views illus- 

 trating irrigation ; to Mr. Edward L. Wilson, of New York City, 

 for the gift of a number of views of Natal and the Azores, as well 

 as for assistance in procuring views from South Africa and New 

 Zealand. About six hundred and fifty pictures have in all been 

 added to the collection during the year.
