1. A tortured spruce sentinel near the upper limit of trees on Snowy Range Pass (10,800 

 feet) in the Medicine Bow Mountains of southcentral Wyoming, tellingly pointing all its 

 branches in the direction of the prevailing winds. Here can be seen the interdigitating 

 of forest and alpine and a tendency toward the development of typical timberline 

 Krummhoh. 



2. The Arctic bkicbcrry, / acciniuni uliginosum L., is an abundant low shrub of the Tundra 

 in all quarters of the Arctic. The fruits are often quite oblong as in this picture (about 

 one-half life size).
