and 13 inches in diameter. The numerous fires which have been allowed to run over this area have so reduced the stock that its stumpage value at maturity will be about $1,500,000, or, in other words, the fires have cost, in terms of pine stumpage, nearly $2,400,000, and the dues on the young pine burned would have amounted to $680,000. So the fires have destroyed more than $3,000,000 in poten-
tial pine values. As a result of the fires, however, we have sufficient poplar to make, at maturity, 265,000 cords of pulpwood. Considering this to be worth one dollar a cord when ready to harvest, we have $265,000 to deduct from the cost of the fires. So the final charge against the forest fires, in terms of potential value of pine destroyed, is, approximately, $2,800,000.
While the value of poplar is very much less than that of the pine, yet the successive fires have very materially lessened the potential value of its crop. Assuming the poplar to be worth one dollar a cord on the stump, for pulpwood, and that it could be harvested 30 years hence, the following data may be given in regard to the reduction of its value on the areas burned more than once:
