FOREST TREES
The beauty of a forest is not simple in character, but is due to many separate sources. The trees contribute much; the shrubs, the rocks, the mosses, play their part; the purity of the air, the forest silence, the music of wind in the trees—these and other influences combine to produce woodland beauty and charm. A first consideration, however, should be to know the beauty that is revealed by the trees themselves.
Here it will be wise to make a selection: to choose out of the great variety of our forest flora those trees that most deserve our attention. Many of our forest trees have naturally a restricted range; others are narrowing or widening their range through human interference; still others have already established their right to a preëminence among the trees of the future, because, possessing to an unusual degree the qualities that will make them amenable to the new and improved methods of treatment known as “forestry,” they are certain to receive special care and attention; while those that are not so fortunate will be left to fight their own battles, or may even be exterminated to make room for the more useful kinds. Among all these the rarest are not necessarily the most beautiful. Those that are commonest and most useful are often distinguished for qualities that please the eye or appeal directly to the mind.
In accordance with the ideas already expressed in the Preface, the considerations that will determine what trees shall be described are as follows: first, trees of beauty; next, those that are common and familiar; finally, those that are important both for the present and the future because they are useful and have an extended geographical distribution.
The trees selected for description will here be divided into the two conventional groups of broadleaf species and conifers, beginning with the former.
THE BROADLEAF TREES
In the “Landscape Gardening” of Downing we read concerning the oak,—
“When we consider its great and surpassing utility and beauty, we are fully disposed to concede it the first rank among the denizens of the forest. Springing up with a noble trunk, and stretching out its broad limbs over the soil,
‘These monarchs of the wood,
Dark, gnarled, centennial oaks,’
