THE CANADIAN FORESTER S 



is one of the principal causes of the rapid disappearance 

 of this tree ; for, unfortunately, bark is harvested for 

 sale to the tanners, and the unhappy tree is left to pe- 

 rish where it lies. Eng. 96, p. 105, shows the hemlock-

White-oak. 



Thus, the sylvan flora of Ontario, regarded from the 

 forester's point of view, and setting aside, as I have 

 done, all tlie shrubs and the comparatively useless trees, 

 is composed of the following species : 



Abies alba While-spruce. 



Abies Americana Double-balsam ilr. 



Abies balsamifera Balsam flr. 



Abies excelsa Norway spruce. 



Abies nigra Black-spruce. 



Acer dasycarpum Silver-maple. 



Acer Pennsylvanicum Stripe rl-maple. 



Acer ru brum Red-maple. 



Acer saccharinum Sugar-maple. 



Acer spicatum Mountain-maple. 



Belula excelsa Yellow-birch. 



Betulalenta Black-birch. 



Betula nigra Red-birch. 



Betula papyrifera Ganoe-bircli. 



Betula populifolia Poplar-leaved birch. 



Garpinus Americana Hornbeam. 



Carya alba Shell-bark hickory.
