 tones they herald the victory of Spring over Winter. 



The season of cold waves lias passed, and the birds 

 iKnv appear with the regularity of calendar events. 

 From ^lay 1 to 12 the migration readies its lieight. 

 It is a time of intense interest to the l)ird student, and 

 happy is he who can spend unlimited time aliekl. 

 Some mornings we may find ten or more different spe- 

 cies that have come back to us, and each one may
