changes which permitted a great expansion of our research 

 activities. The Rockefeller Foundation had provided 

 money for a new biological building, which took most of 

 the old laboratories out of the Museum where they had 

 been for years, but the space so vacated was still not 

 enough. 



I had long had the idea that we exhibited many more 

 objects than there was need to show to our rather limited 

 public, and I felt that by condensing our exhibits we could 

 eliminate obsolete and badly prepared material and at the 

 same time gain space for expansion of the research col- 

 lections. This I did by flooring over the galleries in nine 

 rooms and rearranging all of the exhibitions on the third 

 floor of the building, with the exception of our paleonto- 

 logical specimens. This scheme has worked out very satisfac- 

 torily. Our research collections, which are now expanded, 

 well-arranged, and quite accessible, are as much a credit to 

 the University as is its great Library. Of course, I can take 

 only small credit for this. It was a labor of love for many. 

 In 1926 electric lights were installed throughout the 

 building (there had only been gas before!) and they and 

 an electric elevator improved the working conditions. 



Professor Louis Agassiz designed the standard tray 

 which we have used throughout the Museum except in 

 the Departments of Birds and Mammals, where we have 

 received many good storage cases which came to us with 

 the Brewster, Thayer, Bent, Kennard, and Batchelder col- 

 lections. Since birds are so different in size, our arrange- 

 ment in this department is more or less haphazard. The 

 same applies to the mammals except that with these we tan
