Forests and Trees 



It is a graceful tree with long branches and beautifully 

 lobed leaves, bright green above and silver-white beneath. 

 The bark is thick and rough on the old trees, but on young stems 

 is thin, smooth and a beautiful silvery-gray. 



It is a tree well worth cultivating where its growth is as- 

 sured, but it does not seem to mature its seeds in Manitoba. 

 I have tried in vain to germinate them, and have never been 

 able to find any young trees growing where the seed falls.

4. BROAD-LEAVED MAPLE. Acer macrophyllum. Pursh. 



The broad-leaved maple is so called on account of the size 

 of its leaves, which are six or eight inches across when full 

 grown. The leaves are deeply three or five-lobed, on long 

 petioles, and heart-shaped at the base. They are dark green, 

 shiny above and lighter beneath, and coarsely toothed or wavy 

 on the margin. When young they are densely hairy, but almost 

 naked when mature. 



The bark is grayish-brown, rather thick and scaly on old 

 trunks, but thin and smooth on the branches. The twigs are 

 red in winter but afterwards turn gray.
