change made in the exhibits under his charge was the replacement of 

 certain specimens in the stratigraphic exhibit by jars containing samples 

 of the sands, soils, gravels, and clays of the island. He has been prevented 

 by his long absence in Washington from taking his usual active part in the 

 work of the museum. 



The honorary curator of botany. Dr. Dowell, has little to report in his 

 department. Until new, insect-proof cases can be provided for the 

 herbarium, there is no opportunity for rearrangement or for the addition 

 of mounted sheets. 



Dr. Adams, honorary curator of art, was made acting secretary of the 

 Association during the absence of Dr. Hollick and hence has been unable 

 to give as much attention as usual to this department. He personally 

 selected the wall papers used in decorating the Museum and has frequently 

 cheered and aided the curator-in-chief with his advice. 



Library 



In my last annual report I referred to our urgent need for certain 

 standard textbooks in various branches of biology. This need is more 

 pressing, in view of the increased number of inquiries received and the 

 importance of securing exact information in preparing our exhibition 

 labels. There is also a large accumulation of pamphlets awaiting binding, 

 and these are constantly deteriorating while they remain unbound. The 

 president of the Association has authorized a subscription fund for this 

 purpose, and the June issue of the Museum Bulletin will take up the 

 subject in detail. 



There are at present 71 institutions on our exchange list. 317 publica- 

 tions were received during the year. Seven are received as gifts from 

 Miss Agnes L. Pollard, Messrs. William T. Davis, Arthur Hollick, and 

 Charles L. Pollard ; eight are deposited as loans by Mr. Howard H. 

 Cleaves and Mr. Pollard. Three new exchanges were added, the Bulletin 

 of the Charleston Museum, the University of North Dakota Quarterly, 

 and the Transactions of the Connecticut Academy of Arts and Sciences. 

 The publication of the Augustana College and Theological Seminary was 

 dropped from the exchange list. 



In addition to the above regular list 486 separates and special reports 

 and bound books have been received from individuals and institutions 

 during the year. 



Museum Cooperation 



The present tendency among museums is toward concentration of effort 

 along special lines, in which affiliated institutions may be of mutual 

 assistance. Thus the Brooklyn Museum, by virtue of the many valuable 

 gifts of shells which it has received, may be said to have made a feature 

 of conchology. Through the courtesy of Dr. Frederic A. Lucas, the
