STAND TABLES. 



Tables 50 to 53 are all stand tables for the spruce slope type and 

 serve as a rough basis for comparison between the four States within 

 which the red spruce principally occurs. The principal associates are 

 balsam, yellow birch, beech, hemlock, sugar maple, and red maple, 

 with incidental arborvitse, white pine, and numerous hardwoods. 

 These vary much from one place to another.
