PTARMIGAN-SHOOTING. Ill 



evergreen plant which grows only among the rocks on the 

 hill-tops. The previous autumn I killed another ptarmigan 

 after feed, and its crop also was charged with the very same 

 food. No doubt this rock-plant is as necessary to the ptar- 

 migan as heather to the grouse; and although both may 

 occasionally vary their diet, yet without these staple nourish- 

 ments they would never thrive, or even live.
