MAPLE. 



The lumber trade recognizes two kinds of maple — hard and soft. 

 Hard-maple lumber comes from the sugar-maple tree and soft-maplo 

 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 sacclicurmri) and silver maple {Acer 

 saccharinum) are lumbered principally in the Northern States. Red 

 maple {Acer rubruni) 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 

 splcatuni) and striped maple {Acer jyenns^ylvanicum^. Oregon 

 maple {Acer macrophylliMm) is cut in the Pacific Coast States.

RED GUM. 



Red (or sweet) gum {TAquidawJ)ar styracifua) is a single species, 

 and what is commercially known as " sap gum " is the sap wood of the 

 red gum tree. It is of most importance commer<;ially in the lower 

 Mississippi Valley, but is also cut farther east and north.
