22 Report of the President. 



Ancient and the Serpent Mound in Ohio; also of the Cahokia 

 Mound in Illinois, the largest prehistoric mound in the United 

 States. This model was based on a clay one made for us by 

 Mr. David I. Bushnell, Jr. A model of two effigy mounds, 

 representing animals in Wisconsin was also constructed. 



The department has begun arrangements with museums 

 and private collectors to obtain the loan of important speci- 

 mens for the purpose of making casts to fill in certain gaps in 

 the Museum collections, and also to be used in connection 

 with the publications resulting from our own expeditions to 

 the North Pacific coast. The Museum has received such loan 

 material from the Peabody Academy of Sciences, Salem, 

 Mass. ; the Oregon Historical Society, Portland; and Mr. C. P. 

 Wilcomb, of San Francisco. Casts of these specimens 

 have been made by the Department of Preparation and 

 Installation. 



The department has also begun the work of making casts 

 from some of the noteworthy objects of ancient art from 

 Mexico and Central America for exchange with other museums 

 for casts of rare material of a like character. A set has been 

 sent to the United States National Museum, which was 

 exhibited at the Louisiana Purchase Exposition at St. Louis. 

 Arrangements have recently been made for an exchange of 

 casts with the Berlin Ethnographical Museum. 



The specimens received during the year have been cata- 

 logued, and many labels, maps and drawings have been pre- 

 pared and placed with the collections on exhibition. Certain 

 rearrangements in the Mexican Hall have been undertaken, 

 and the West Indian collections have been removed to the 

 South American Hall. 



A synoptic collection was brought together and loaned to 

 Teachers College. This was made up so far as possible from 

 duplicate material. A second collection was selected, labeled 

 and loaned to the Ethical Culture School. This has been 

 returned and is about to be installed as an exhibit for school 

 children. 



The following publications have been issued by the 

 department:
