Therefore, our slogan must be "Prevent Forest Fires, It ; A study of the forest fire statistics in Lesson Twenty will impress one with the serious fact that our i)e()])le are permitting millions of acres of land to be burned over and millions of dollars worth of natural resources to be wasted. In the 10-year period 1913-1922, 2,647,000 acres were burned, or an average of more than a quarter-million acres per year with a direct loss of more than one-half million dollars annually. The figures are alarming enough but nevertheless they indicate that some progress is being made in forest j^rotection. However, the loss resulting from forest fires is entirely unnecessary because forest fires are the result of carelessness. They do almost no good, but if the labor and materials required for their extinction were used in construc- tive work in forests perpetual benefits would result. Although the figures for the 18-year period indicate that almost four million acres have burned over, this is not extactly the right con- clusion to reach. The fires of successive years do not occur on areas not i^reviously burned, but rather they occur time after time upon the same area. Sometimes the same area will burn over each year. Other areas burn over every two or three years; still others burn over less frequently. It is safe to estimate that the area burned over several times in the 20-year period will not exceed two million acres. Assuming that this area is now being kept in a non-productive con- dition by fires and that this land in forest growth could produce at least. 250 board feet per acre per year, we must realize that forest fires are keeping the landowners from growi
