size and amount of timber to be expected from these trees forty years 

 hence. The thickets of young growth were also considered, and their 

 probable future yield determined. 



Table 1 shows the classification of lands on the experimental area. 

 It will be seen that 467 acres are classed as "Pole stand" and 1,724 

 acres as "Pine thicket." The pole stand consists of trees from 40 to 

 60 years old that have come up in openings in the forest made by old 

 fires. The pine thicket is a dense stand of young pine from 15 to 25 

 years old, much of which has come in on old burns or cuttings. 



TABLE 1. Land classification of experimental area. 



On the 5,804 acres of cut-over pine land there is a fair representa- 

 tion of trees left after logging because of their small size. These 

 trees are to form the basis of the future cut on such land, and will 

 also serve to seed up the open areas in their neighborhood. Most of 

 the trees are sound and thrifty, and due allowance was made for those 

 which showed defects serious enough to cause death before a second 

 cut. 



FUTURE YIELD. 



The estimate of the future yield on the experimental area was made 

 from growth figures obtained from trees now on the ground. The 

 growth during the next forty years only was calculated, since by the 

 end of that period the company will probably have cut all of its 

 virgin timber and will be ready to log its land a second time. 



Table 2 shows the probable future yield on the 5,804 acres of cut- 

 over pine land and its probable value at the time of cutting. The price 

 of stumpage at the end of forty years can only be guessed at, but 

 it is safe to assume that it will be much greater than at present. 

 For this reason, in estimating the returns, stumpage values of from 

 $3 to $6 per thousand feet were given. 



The present yield on the fir type, cutting to a diameter of 12 inches 

 breast-high, would be 34,000,000 feet. No figures were obtained from 

 which the future yield on this type could be estimated, but it is safe 

 to say that it will be much greater than at present. 



The yield of the pine thicket in forty years will be about 20,250 

 feet per acre, or a total of 34,911,000 feet, which would give a total 

 yield of pine for the experimental area of 75,835,000 board feet.
