42 Bird-Land Echoes. 



century with half-century, there docs appear to 

 be less snow than in the days of our grandfathers, 

 and my observations give me the impression that 

 there are fewer snow-birds. I have kept no record 

 — if, indeed, a satisfactory one could have been 

 kept — as to these birds, but as I recall them, when 

 a boy, and compare these recollections with present

 They are more uncertain : here to-day and gone to-

 to sport in it to the same extent, and seek the shelter 

 of greenbrier thickets. If, then, we had more 

 snows years ago, and, consequently, the snow-birds
