With this number we complete the Fourth Volume 

 of the Journal of the Union. The Editors hope 

 that the first Migration Report published in this 

 volume will stimulate Members to greater activity in 

 this important matter. To our European friends we 

 offer it as a modest beginning, trusting that we may 

 in time throw some light upon the movements of 

 their migratory visitors. We have to thank the 

 Members for the support accorded us in the past, 

 and hope that a few more of the active workers will 

 publish in the Journal, the percentage of Members 

 who contribute towards its contents being still very 

 small.
