 American Ornithologists' Union. 



The Twenty-third Annual Congress 

 of the American Ornithologists' Union 

 was held at the American Museum of 



Natural History, New York City, with 

 the exception of the final session, 

 which was at the Brooklyn Institute 

 of Arts and Sciences. Meetings open 

 to the public were held forenoon and 

 afternoon, Nov.^ 14, 15, and 16, the pro- 

 grams being made up of the reading, 

 illustration and discussion of papers 

 by members. Liincheon was served 

 at noon on each day of the three days, 

 by the Linnaen Society of New York,

 The third paper was "Summer Birds 

 of the Mt. Marcy Region in the Adi-

 many birds, and recounted interesting 

 facts regarding them in their north-
