would be entirely feasible, since the longest haul 

 would rarely exceed 1 2 miles. 



Gum yields of second-growth longleaf in this area 

 have not been determined, but it is believed that 

 they will equal or exceed yields from second-growth 

 stands in the adjoining States of Louisiana and 

 Mississippi, where the average operation during 

 1933 produced 43 units per crop on the basis of 34 

 streaks per season. 



Wood Naval Stores 



Although old-growth longleaf pine stumps have 

 been accumulating in this unit since before 1900, 

 the present supply is not as great as might be 

 expected. Fires and decay have constantly reduced 

 the volume, and the restocking of cut-over land by 

 young trees has lessened the present availability of 

 otherwise merchantable stumps. No commercial 

 utilization of stump wood had occurred up to the 

 end of 1936. 



Supplies of suitable stumps are found mainly in 

 the longleaf type and in areas formerly of this type 

 but now covered by scrub hardwood — an area 

 totaling 612,400 acres. Practically all of the 

 available tonnage is in the flatwoods and rolling 

 uplands; less than 1 percent is in swamps and river 

 bottoms. 



As a rule, the difficulty and cost of removing 

 stumps increase with the age and density of the 

 timber stand. Of the total area, 25 percent is 

 covered with saw-timber stands, 45 percent with 

 young second growth, and nearly 30 percent, or 

 179,000 acres, located chiefly in the eastern part 

 of the unit (fig. 16), is clear-cut. Over 63 percent 

 of the clear-cut area and 45 percent of the total 

 stump-wood area have 14 or more stumps per acre. 



The total quantity of stumps at present mer- 

 chantable and suitable for removal by blasting is 

 about 2 million tons (table 22). Merchantable 

 stumps on clear-cut longleaf land amount to 

 730,000 tons, or about 38 percent of the present

LOCATION OF PRINCIPAL 

 SUPPLY OF MERCHANTABLE 

 LONGLEAF STUMPS 



Figure 16. — Location of the principal supply of merchantable 

 longleaf stumps as indicated by shading 



merchantable stump wood. Stumps on areas 

 stocked to reproduction and young second growth 

 amount to 863,000 tons. In addition, there are 

 345,000 tons in sawlog-size stands. About 76 

 percent of the total merchantable volume occurs in 

 densities of at least 14 stumps per acre.
