220 WAKIjl-ROBIN 



I first verified this observation some years ago. 

 I had long been familiar with the soiig, but had 

 only strongly suspected the author of it, when, as I 

 was walking in the woods one evening, just' as the 

 leaves were putting out, I saw one of these birds 

 but a few rods from me. I was saying to myself,

 sparrows which I came upon one March day, all of 

 them evidently much reduced, one was so feeble

During the present season, a very severe cold 

 spell the first week in March drove the bluebirds
