[Dec., 
Three hundred and thirty-nine lantern slides have been added to the 
collection as a loan from the Ludwick Institute. These are dis- 
tinguished in the catalogue by blue cards. 
The intelligence and reliability of my assistant, William J. Fox, in the 
discharge of his duties, both in the Library and in connection with the 
publications of the Academy, are again gladly acknowledged.

REPORT OF THE CURATORS. 
The collections in the care of the Curators are in excellent condition, 
while much progress has been made during the year in their study and 
classification. 
Early in the year work was begun upon the new concrete and steel 
roof for the Library building, for which the Academy received an appro-

with those previously installed have been ordered for birds, inver-

A number of air-tight metal storage cases have been provided for the 
bird and mammal skins and for the Herbarium. 
Mr. Clarence B. Moore has continued his exploration of the Indian

representing 700 species. 
Dr. Henry Skinner visited Idaho in the interest of the Academy for
