MAPLE. 
The lumber trade recognizes two kinds of maple — hard and soft. 
Hard-maple lumber comes from the sugar-maple tree and soft-maple 
lumber from the silver and red species. These three species have a 
botanical range covering the eastern half of the United States. 
Sugar (or hard) maple (Acer saccharum) and silver maple (Acer 
sacchariruum) are lumbered principally in the Northern States. Red 
maple (Acer rubrum) is most important as a timber tree in the 
Southern States. Both silver and red maple are commonlv called 
soft maple. 
Eastern species of minor importance are mountain maple (Acer 
spicatum) and striped maple (Acer ptennsylvanicwm) . Oregon 
maple ( Acer macrophyllum) is cut in the Pacific Coast States.

and what is commercially known as " sap gum " is the sapwood of the 
red gum tree, It is of most importance commercially in the lower 
Mississippi Valley, but is also cut farther east and north.
