EDITORIAL 



The American Ornithologists Union convened for its thirty-fourth 

 stated meeting for a three-day session in Philadelphia, at the Acad- 

 emy, of Natural Sciences, November 14 to 16. The attendance of 

 members from all parts of the country was the largest in its his- 

 tory. The' program was varied with motion pictures of birds and 

 accounts of explorations in remote fields. Mr. James P. Chapin's 

 paper on " Bird Migration in Central Africa," and Dr. W. H. 

 Bergtold's paper on " What Determines the Length of Incuba- 

 tion," were among the most valuable contributions to the long list 

 of interesting and valuable papers. 



The fourth annual meeting of the Wilson Ornithological Club 

 will be held at the Morrison Hotel, Chicago, December 27 and 

 28, 1916. There is good prospect of a large attendance and an 

 attractive program. This meeting furnishes an opportunity to 

 bird lovers of the central' districts of the country to meet for 

 mutual acquaintance, such as is furnished by the Cooper Club 

 meetings in California for the people of the Pacific slope, and the 

 meetings of the various organizations on the Atlantic slope. Let 

 us take advantage of this rare opportunity.
