Acer Pennsylvanicum — Striped- Maple. 



When speaking of the Mountain-maple, I say that it 

 should be preserved in the numerous hilly districts 

 where it is found, and allowed to shoot again from the 

 ' stump ; and so with the striped maple. It servesth e 

 same purpose as the other, namely, to prevent the earth 

 from being washed away, and the rock from being 

 denuded of its covering. It is never found more than 

 twenty feet high. Engraving No. 1, p. 38, shows the leaf 

 of this maple and engraving No. 2, same page, its seeds
