 when sometimes there is a marked renewal of song. Flocks are 

 then seen and sometimes noted passing in somewhat scattered 

 bands southward, giving their pleasant good-bye calls, "far-a- 

 way, far-a-way, far-a-way," as they move high in the air, often 

 not easily discernible in the blue sky. Such flights occur even 

 in early November days, when, I am informed, it may be the 

 case that much of the day at intervals this call of passing Blue- 

 birds is heard, coming to sensitive ears while the work of the 

 farm proceeds.
