Report of the President 55 



the Brooklyn Institute of Arts and Sciences and through the 

 generosity of Arthur Curtiss James, returned in May, having 

 been gone one year. In spite of unfavorable conditions, Mr. 

 Murphy secured a representative collection of the birds and 

 mammals of those subarctic islands and took more than 400 

 photographs. 



The Brewster-Sanford expedition to South America under 

 the charge of Rollo H. Beck, began work in the vicinity of 

 Lima, Peru, early in the year. From this point as a base, 

 collections were made at Lake Junin, on the summit of the 

 Andes, and on the waters of the Pacific well off-shore; subse- 

 quently Lake Titicaca was visited. The collections already 

 received number 1,500 specimens and a second shipment is 

 en route. These birds are deposited in the Brewster-Sanford 

 collection in the Museum, where they are accessible for inves- 

 tigation. Almost all this material is new to the Museum, and 

 has proved to be of much practical and scientific value. 



The private collection of Jonathan Dwight, Jr., deposited 

 in the Museum some years ago, has been enriched during the 

 year by important specimens of birds from China. Dr. 

 Dwight's collection, which is available for study, now numbers 

 more than 10,000 specimens.

 specimens of Stone Sheep and Mountain Goat have been com- 

 bined in groups. The Alaska Moose has been placed in a 

 separate case and forms an imposing exhibit at the entrance 

 to the hall. These changes have greatly improved the 

 appearance of the North American Mammal Hall, for which 

 further improvements have been planned. 



The central mammal hall has been greatly changed by the
