A LABRADOR SPRING 



Whether in the future ages the ptarmigan 

 will reach the stage of the spruce partridge, and 

 the latter that of the ruffed grouse, or whether 

 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.
