It appears that in a forest like this the great majority of flowers, shrubs, and grasses are confined to the banks of the rivers and lakes, and to the meadows, more open swamps, burnt lands, and mountain-tops; comparatively very few indeed penetrate the woods. There is no such dispersion even of wild-flowers as is commonly supposed, or as exists in a cleared and settled country. Most of our wild-flowers, so called, may be considered as naturalized in the localities where they grow. Rivers and lakes are the great protectors of such plants against the aggressions of the forest, by their annual rise and fall keeping open a narrow strip where these more delicate plants have light and space in which to grow. They are the protégés of the rivers. These narrow and straggling bands and isolated groups are, in a sense, the pioneers of civilization. Birds, quadrupeds, insects, and man also, in the main, follow the flowers, and the latter in his turn makes more room for them and for berry-bearing shrubs, birds, and small quadrupeds. One settler told me that not only blackberries and raspberries but mountain maples came in, in the clearing and burning.
