THE different forms of trees, and their endless variety of foliage and spray, have, from the earliest times, been favorite studies of the painter and the naturalist. Not only has each species certain distinguishing marks, but their specific characters are greatly modified in individual trees. The Psalmist compares a godly man to a tree that is planted by rivers of water, whose leaf shall not wither, seeing in the stateliness and beauty of such a tree an emblem of the noble virtues of the human heart. Trees are distinguished by their grandeur or their elegance, by their primness or their grace, by the stiffness of their leaves and branches or by their waving and tremulous motions. Some stand forth as if in defiance of the wind and the tempest; others, with long drooping branches, find security in bending to the gale, like the slender herbs in the meadow. Trees are generally classed as landscape ornaments, according to their general outlines. "Some trees ascend vertically," says St. Pierre, "and having arrived at a certain height, in an air perfectly unobstructed, fork off in various tiers, and send out their branches horizontally, like an apple-tree; or incline them towards the earth, like a fir; or hollow them in the form of a cup, like the sassafras; or round them into the shape of a mushroom, like the pine; or straighten them into a pyramid, like the poplar; or roll them as wool upon the distaff, like the cypress; or suffer them to float at the discretion of the winds, like the birch." These are the normal varieties in the shape of trees. Others may be termed accidental, like those of the tall and imperfectly developed trees, which have been cramped by growing in dense assemblages, and of the pollards that have issued from the stumps and roots of other trees. Trees are generally wanting in that kind of beauty which we admire in a vase, or an elegant piece of furniture. They have more of those qualities we look for in a picture and in the ruder works of architecture. Nature is neither geometrical nor precise in her delineations. She betrays a design in all her works, but never casts two objects in the same mould. She does not paint by formulas, nor build by square and compass, nor plant by a line and dibble; she takes no note of formal arrangements, or of the "line of beauty," or of direct adaptation of means to ends. She shakes all things together, as in a dice-box, and as they fall out there they remain, growing crooked or straight, mean or magnificent, beautiful or ugly, but adapted by the infinite variety of their forms and dispositions to the wants and habits of all creatures. The beauty of trees is something that exists chiefly in our imagination. We admire them for their evident adaptation to purposes of shade and shelter. Some of them we regard as symbols or images of a fine poetic sentiment. Such are the slender willows and poplars, that remind us of grace and refinement, becoming the emblems of some agreeable moral affection, or the embodiment of some striking metaphor. Thus Coleridge personifies the white birch as the "Lady of the Woods," and the oak by other poets is called the monarch, and the ash the Venus of the forest. The weeping willow, beautiful on account of its graceful spray, becomes still more so when regarded as the emblem of sorrow. The oak, in like manner, is interesting as the symbol of strength and fortitude. A young fir-tree always reminds us of primness; hence the name of spruce, which is applied to many of the species, is a word used to express formality. The cedar of Lebanon would be viewed by all with a certain romantic interest, on account of the frequent mention of it in Holy Writ, as well as for its nobleness. of dimensions and stature. It is with certain interesting scenes in the romance of travel that we associate the palms of the tropics. They have acquired singular attractions by appearing frequently in scenes that represent the life and manners of the simple inhabitants of the equatorial regions. We see them in pictures bending their fan-like heads majestically over the humble hut of the Indian, supplying him at once with milk, bread, and fruit, and affording him the luxury of their shade. They emblemize the beneficence of nature, which, by means of their products, supplies the wants of man before he has learned the arts of civilized life. Writers in general apply the term "picturesque" to trees which are devoid of symmetry and very irregular in their outlines, either crooked from age or from some natural eccentricity of growth. Thus the tupelo is so called, to distinguish it from round-headed and symmetrical or beautiful trees. This distinction is not very precise; but it is sanctioned by general use, and answers very well for common purposes of vague description. I shall use the words in a similar manner, not adhering to the distinction as philosophical. Indeed, it is impossible to find words that will clearly express a complex idea. Words are very much like tunes played on a jew's-harp; the notes intended to be given by the performer are accompanied by the louder ring of the key-note of the instrument, making it difficult to detect the notes of the tune, except in the hands of an extraordinary performer. Nature has provided against the disagreeable effects that would result from the dismemberment of trees, by giving to those which are the most common a great irregularity of outline, admitting of disproportion without deformity. Symmetry in the forms of natural objects becomes wearisome by making too great a demand upon the attention required for observing the order and relations of the different parts. But if the objects in the landscape be irregular, both in their forms and their distribution, we make no effort to attend to the relations of parts to the whole, because no such harmony is indicated. Such a scene has the beauty of repose. The opposite effect is observed in works of architecture, in which irregularity puzzles the mind to discover the mutual relations of parts, and becomes disagreeable by disturbing our calculations and disappointing our curiosity. The charm of art is variety combined with uniformity; the charm of nature is variety without uniformity. Nature speaks to us in prose, art in verse. Though we always admire a perfectly symmetrical oak or elm, because such perfection is rare, it will be admitted that the irregular forms of trees are more productive of agreeable impressions on the mind. The oak, one of the most interesting of all trees, is, in an important sense, absolutely ugly, especially when old age has increased its picturesque attractions. Indeed, if we could always reason correctly on the subjects of our consciousness, we should find that a very small part of that complex quality which we call beauty yields any organic pleasure to the sight. The charm of most of the objects in this category exists only in our imaginations. In trees and the general objects of the landscape we look neither for symmetry nor proportion; the absence of these qualities is, therefore, never disagreeable. It is the nonfulfilment of some expectation, or the apparently imperfect supply of some important want, that offends the sight, as when a conspicuous gap occurs in some finely proportioned work of art. |
