In the 10-vear period V)\yV)ll, 2, acres were hin-ned. or an averaiL^e of more than a (|uarter-nnllion acres per yeaj- with a direct loss of more than one-half million dollars annuallv.

However, the loss resulting irom forest hres is entirely unnecessary heeause forest tires are the re>ult of carelessness. They do almost no i^ood. hut if the Ial)(»r and materials re(|iu"re(l for their extinction were used in construc- tive work in forests ])eri)etual henelits would result. Althout^di the tiouR's for the IS-vear period indicate that almost tour nu"llion acres ha\e hiu-ned over, this is not extactiv the rij^ht con- clusion to reach. The hres of successive years do not occur on areas not i)reviously hurned. hut rather they occin- time after time upon the same area. Sometimes the same area will hiu-n over each year. ( )ther areas hurn over every two or three years; >\\\\ others hurn over less fretpiently. It is .safe to estimate that the area hurned over several times in the 2()-year period will not exceed two nullion acres.
