Excerpt from The Geographical Distribution of the Forest Trees of Canada, Vol. 1 Causes. Ders of the forests of the continent the elevation of the land above the sea is comparatively slight and regular, and the other physical condi tions are tolerably uniform. As a consequence, we find the most northern group of trees extending from Newfoundland into Alaska, a distance of about miles. Peculiarities. An inspection of the accompanying map will show some interesting features as to the general distribution Of our forest trees, as well as regarding almost every individual species of timber. For example, it will be observed that there is no material change in the woods through out the great triangular area embracing about square miles, of which the national boundary line between the Rocky Mountains and Lake Superior forms the base, and the Rocky Mountains and Lauren tian hills respectively the west and east sides, the apex being at the mouth of the Mackenzie River. In the southern part of this area, a number of species are added to the kinds which everywhere through out it make up the bulk of the forests, and again, few trees of any kind are found to the south of the North Saskatchewan still, making allow ance for local peculiarities of condition, there is a remarkable uniformity in the timber of this enormous area. It includes, however, only a few species, of which the aspen, balsam poplar and willows are more abundant towards the western, and the spruces, larch, balsam fir and Banksian pine towards the eastern side of the area.
