The Hemlock Association. 



The pure Hemlock occurs in small isolated groups. Alto-

The average density of 180 trees per acre is made up as fol-

Hemlock 87 per cent. 



Yellow Birch 8 



Cedar 3 



Balsam Fir i

The reproduction is very dense, and Hemlock, which averages 

 6,800 seedlings to the acre, forms 85 per cent, of the whole. The

Cedar 6 



White Pine 4 



Hard Maple 2
