UNITED STATES SHOULD PRACTICE FORESTRY 123 



believe that our reserves will last only sixteen 

 years unless measures to protect them are put in- 

 to effect at once. At the present rate of cutting 

 long-leaf pine trees, our outputs of naval stores 

 including turpentine and rosin are dwindling. 

 We cannot afford to increase our export of south- 

 ern yellow pine unless reforestation is started on 

 all land suitable for that purpose. Our pine lands 

 of the southern states must be restocked and 

 made permanently productive. Then they could 

 maintain the turpentine industry, provide all the 

 lumber of this kind we need for home use, and 

 supply a larger surplus for export. 



Although our supplies of Douglas fir, western 

 white pine, sugar pine and western yellow pine 

 are still large, they will have to bear an extra 

 burden when all the southern pine is gone. This 

 indicates that the large supplies of these woods 

 will not last as long as we would wish. To pre- 

 vent overtaxing their production, it is essential 

 that part of the load be passed to the southern 

 pine cut-over lands. By proper protection and 

 renewal of our forests, we can increase our pro- 

 duction of lumber and still have a permanent 

 supply. The Forest Service estimates that by 

 protecting our cut-over and waste lands from fire
