In addition to the 2 million tons of stumps at 

 present available for removal by blasting, there 

 are nearly 1 % million tons of well-seasoned stumps 

 located in timber stands so thick that stump wood 

 operations are impracticable at present. Old- 

 growth longleaf pine trees now standing are also 

 a potential source of stumps. On the basis of 6 

 tons per acre, there will be at least 700,000 tons 

 of stump wood resulting from the removal of the 

 present old-growth longleaf stands. On the ground 

 there is also an unmeasured supply of seasoned 



top wood that can be used in the manufacture of 

 wood naval stores, as has been done since about 

 1910. 



Considering only the amount of merchantable 

 stump wood at present available, there is enough 

 to supply 78,000 tons per annum over a 25-year 

 period. Calculations based on present yields in 

 steam and solvent plants show that this tonnage 

 would produce annually 63,000 barrels of rosin, 

 12,000 barrels of turpentine, and 390,000 gallons 

 of pine oil.
