Pine seedlying, under natural conditions, where it is subject to various changes of moistureand temperature would not be likely to grow after five years. Some of the outstanding features in the life of the White Birch will do toshow the ability of this class of trees to reproduce. The Birch produces its seed ina cone-like fruit, which often remains on the tree throughout the early part of thewinter. Unlike the White Pine the seed does not all fall to the ground in earlyautumn, but gradually falls throug^hout the winter months. It is a common sightto see the small, winged seed of the birch being carried for miles on the surface ofthe snow. This is one factor explaining the prevalence of Birch on burned andcut over areas. 102 EEPOET OF. THE ¥o. 3

This sproutgrowth often follows light fires and cutting operations. The ability of Birch, Pop-lar and many of the hardwoods to reproduce by this method explains why many cutor burned over areas reproduce with Birch, Poplar and other hardwoods. The Pines can reproduce only by the seed method and are therefore handicappedat first in the struggle to take possession of cut over areas. The Pine has, however,the advantage of being able to start under the shade of the Birches and Poplars; togradually struggle through, and, owing to the short life of the Birches and Poplars,to eventually overcome them. There are few of our White and Red Pine areas which would not become re-stocked if it were
