 appointed to investigate the subject of migration of birds in 

 the United States and British North America. The plan of

 observations already commenced and so ably carried out by 

 the Committee appointed by the British Association will 

 find valued coadjutors in the New World. The Chairman 

 of the American Committee is Dr. C. Hart Merriam.
