yS Bulletin No. 23. 



view to correlating the facts gathered by much hard work and incon- 

 venience, as well as pleasure. I take it for granted that all of us have 

 in mind, in all our study, the advancement of our favorite science by 

 this field work. With that in our mind, it becomes our privilege to place 

 the facts learned where they will do the most good. Just as we are able 

 to come closer to the truth according to the material at our disposal, in 

 the same measure will those who have begun the investigation of some 

 special topic be able to give us the truth. If, then, your note-book is to 

 accomplish the purpose for which it was kept, day after day and week 

 after week, parts of it, at least, must find their way into the hands of our 

 committee-men. Will you not, each one, make it your pleasure to send 

 at once such facts as you may have learned, to the appropriate com- 

 mittee ? Let it be your immediate pleasure. 



But the winter season need not be a time for dullness in bird study to 

 many of us. There is, in the winter months, almost as much that is 

 interesting among the birds as at other times. How many of us are 

 really acquainted with our local winter bird fauna, and with the winter 

 habits of the birds ? Is there not ample room here for a great deal that 

 is new and of great interest ? I sincerely hope that the good work that 

 was begun last winter in the way of making censuses, censo-horizons 

 and horizons of the winter birds may continue with renewed energy and 

 interest. I firmly believe that it is a work worthy of our best efforts : 

 a work that will yield greater results for the same effort than any other 

 field work. Let us fill the January issue with December records, making 

 the month a memorable one in our experience.
