The Spruces (Picea). 

 In their general aspect the spruce trees are similar, being 

 conical in outline and having rather short, four-sided leaves, 

 v^hich spread in all directions on the branches, although thej 



commonly project upward in a manner that gives them a 

 brush-like effect. Leaf buds scaly and generally more or less 

 resinous. 



Norway Spruce (Picea excelsa). — Distinguished by the 

 large cones, 4 or 5 inches long, and the drooping position of 

 the smaller branches. An introduced species. 



White Spruce (Picea Canadensis). — Distinguished by the 

 absence of hairs upon the bark of the smaller branches ; cones 

 oblong, cylindrical.
