itistics this fact should be remembered in comparing the sta- 

 3tics with those of lumber production. 



Nearly or quite 100 different woods are used in this 

 country under their own names, while an unknown number find their 

 way to shops and factories without being identified or separately 

 listed, except under general names. In quantity the softwoods, 

 the needle-leaf or coniferous trees, are most important, but there 

 are a greater number of species among the hardwoods, or broadleaf 

 trees. Yellow pine comes first v/ith more than 8 billion feet, 



llov;ed by white pine with 5 billion, and Douglas fir with a 

 tile more than 2 billion. It should be understood, however, that 

 the term "yellow pine" includes several species the three most im- 

 portant of which are longleaf, short leaf, and loblolly. Oak, in- 

 cluding all species, has nearly 2 billion feet and is the most im- 

 portant hardwood. Maple comes next. 



Dogwood cnmes about halfway down the list with mrre 

 than 7 million board ieet, and of those species mentioned Turkish 



Kxv/ood comes last with less than 3<^ thousand foet, followed by 

 ny others too insignificant to list but making a total of all 

 kinds of more than a million feet. Of the native species, laurel, 

 holly and yucca fall very near the foot of the list in relative 

 quantities used. 



Fifty-five principal industries use wood as raw ma- 

 terial. Their relative importance is hard to indicate, because
