The stand of spruce and balsam av- erages from 15 to 25 thousand feet an acre over the whole area covered by this type, and many stands will cut from 40 to 50 thousand feet to the acre. Where this timber is being cut for pulp wood from 40 to 50 cords per acre is an average yield. Spruce varies in height from 40 to 50 feet on the ridges to 80 or 90 feet on the north slopes and in the heads of coves, where it attains a diameter of three feet. Balsam is smaller and is rarely more than two feet in diameter. In the mature forest reproduction is good, owing to the very favorable mois- ture conditions and the freedom from fire. In dense stands there is a larger percentage of balsam, but where the forest is more open spruce reproduction is favored. On areas that have been cut over and not burnt, the young growth which had started before cut- ting continues to thrive, and on many areas seedlings of both species have started since cutting. Unfortunately, no very heavy cuttings could be studied, since logging for pulp wood has been carried on for only two or three years. Both spruce and balsam need moist humus for successful reproduction, and where fire recurs after cutting neither of these species will be perpetuated. The abundant rainfall, which is heavier on these mountain tops than anywhere else in the State, assisted by the dense shade of these evergreen trees, afl^ords an efficient fire protection for spruce forests while they remain largely in their natural state. But when the trees are removed, allowing the large amount of vegetable matter on the soil and the tree tops left in logging to become dry, fires burn through the remaining timber with disastrous results. The current belief is that it is impossible to keep fires out of this type after logging, and that th
