This procedure results in expos-ing the mineral soil, thus facilitating the reproduction of Douglas fir,which species is considered of superior desirability. Broadcast burningcan be done at a much lower cost than piling and burning. It is reportedthat under favourable conditions this work can be done for as little as25 cents per acre. Probably, however, in most cases, it will cost from5 to 10 cents for each thousand feet of timber cut. Piling and burning are indicated for sections where the cutting isnot clean and where, as a result, the remaining young growth of matureor semi-mature timber must be protected and the fire danger is sogreat as to require the elimination of the slash menace. This method. BRUSH DISPOSAL PROBLEM 45 is very frequently adopted in connection with timber sales by the UnitedStates Forest Service in the Western States. It must, however, be re-garded primarily as a fire-protective measure, and where cutting is donein the winter, as in parts of Minnesota and of the Rocky Mountainregion of the United States, it has been found entirely practicable toburn the brush as the operation proceeds. The added cost of pilingand burning is in part offset by the greater ease of skidding. Lopping.—The disadvantages of burning brush will, under someconditions, outweigh the advantages, thus rendering some other formof brush disposal desirable. For instance, in the Adirondacks, the burn-ing of brush is considered impracticable, partly on account of costand partly on account of the great danger of soil fires, with resultantloss of young and old growth. Silvicultural considerations also enterinto the question, and these
