same nest site have important bearing upon the question of whether 

 birds mate for life, recently agitated in 'The Condor.' 



As Mr. Baldwin points out, much valuable data on the age to which 

 birds live, the length of time that migrants remain at a given spot on 

 their line of flight, the return of young birds to the spot where they were 

 raised, etc., may be secured by this method. 



The practice of trapping renders bird-banding a much more attractive 

 study with more definite returns, and we trust that Mr. Baldwin's success 

 will lead others to follow his example. In this connection attention might 

 be called to similar work that has been carried on in England, especially 

 with reference to the movements of Starlings, where many records of 

 individual birds have been obtained. — W. S.
