SPRUCE. 



While there are a number of spruces largely cut for lumber, two 

 furnish the greater portion. Red spruce (Picea rubens) is the princi- 

 pal source of spruce lumber in New England, New York, and West 

 Virginia, while Sitka spruce (Picea sitchensis) is lumbered on the 

 northern Pacific coast. In the Northeast black spruce (Picea mari- 

 ana) undoubtedly is cut to a small extent for lumber, while white 

 spruce (Picea canadensis) furnishes practically all of the lumber cut 

 in the Lake States. In the Rocky Mountain region Engelmann 

 spruce (Picea engelmanni) is the source of spruce lumber. Table 13 

 shows the production of spruce by States.

MAPLE. 



Several species of maple are cut for lumber in this country, but 

 mills usually report them as one, or, at most, distinguish the wood as 

 hard and soft. Maple lumber in the United States is sawed chiefly 

 from the following species : 



Sugar or hard maple (Acer saccharum) is more abundant than any 

 other. It grows in all States east of the Mississippi River, and in the 

 first tier of States west of that stream from Minnesota to Texas. 



Silver or soft maple (Acer saccharinum) has approximately the 

 same range as sugar maple. 



Red maple (Acer rubrum) is found in all States east of Montana, 

 Wyoming, and Texas. 



Eastern species of minor importance are mountain maple (Acer 

 spicatum), striped maple (Acer pennsylvanicum) , and box elder (Acer 

 negundo), while the Oregon maple (Acer macropliyllum) is cut in the 

 Pacific Coast States.
