These four densely populated regions, containing 

 themselves very large areas of forest land, are now 

 largely dependent upon timber grown and manufac- 

 tured elsewhere and are becoming increasingly de- 

 pendent upon timber which must be shipped the 

 width of the continent. 



The bulk of the building lumber and structural 

 timbers used in the Eastern and Central States during 

 the last 15 years was grown in the pine forests of the 

 South. The virgin pine forests of the South Atlantic 

 and Gulf States have been reduced from about 650 

 billion board feet to about 139 billion feet. The 

 production of yellow-pine lumber is now falling off 

 and within ten years will probably not exceed the re- 

 quirements of the Southern States themselves. 



The United States at one time contained the most 

 extensive temperate zone hardwood forests in the 

 world. One region after another has been cut out. 

 The production of hardwood products on the past 

 scale can not be long continued. The scarcity of high- 

 grade oak, poplar, ash, hickory, walnut, and other 

 standard woods is now placing many American in- 

 dustries in a critical condition. 



The depletion of forest resources is not confined 

 to saw timber. Since 1909, the country has ceased 

 being self-supporting in newsprint paper and now 

 imports two-thirds of the pulp, pulp wood, or news- 

 print which we require. This condition is due in part 

 to timber depletion, in part to failure of the paper 

 industry to expand in our western forest regions as 

 the lumber industry has expanded. In 1919 the pro- 

 duction of turpentine and rosin had fallen off 50 per
