A LABRADOR SPRING 
Whether in the future ages the ptarmigan 
will reach the stage of the spruce partridge, and

they will each branch out on original lines of 
their own, time alone will determine, but in the 
present age they represent very well different 
stages in the evolution of the wonderful per- 
formance of the ruffed grouse.
