A year among the trees

by Wilson Flagg

The flowering of the forest is the conclusion of the beautiful phenomena of spring, and summer cannot be said to begin until we witness the full expansion of its foliage. In the early part of the season each tree displays modifications of verdure peculiar, not only to the species, but to the individual and the situation, and hardly two trees in the wood are shaded alike. As the foliage ripens, the different shades of green become more thoroughly blended into one universal hue; and this uniformity, when perfected, distinguishes the true summer phase of vegetation. As summer advances, this monotony increases until near its close. The only trees that variegate the prospect are the evergreens, by their darker and more imperfect verdure, and one or two rare species, like the catalpa and ailantus, which display a lighter and more lively green, resembling the verdure of early summer.

It may be said, however, in behalf of summer, that no other season affords so good an opportunity to note the different effects of sun and shade in the foliage of the woods and fields. The leaves of the trees and grass are never so beautiful in their summer dress as they appear during the hour preceding sunset, when we view them with the sun shining obliquely toward us. All foliage is more or less transparent, and the rays of the sun, made slightly golden by the refraction of the atmosphere, communicate a brilliant yellow tinge to the leaves, as they shine through them. The same effects are not produced by reflection; for if we look away from the sun, the foliage and grass present a much less attractive appearance. A few hours after noonday, before the sunlight is yellowed by refraction, we may study these phenomena more minutely. When we look in the direction of the light, as I have just remarked, we see the least variety of light and shade; for as every leaf is an imperfect mirror, the surface of the forest presents a glitter that throws a glazed and whitish appearance over the green of the foliage. The whole is a mere glare, so that the landscape is almost without expression when viewed in this manner, and all the tiresome uniformity of summer verdure is aggravated. The only relief for the eye comes from the shadows of isolated trees and small forest groups as they are cast upon the ground.

Now let us turn our eyes in an opposite direction. To obtain the best view, we should look obliquely toward the sun. Then do we behold a magnificent blending of light and shade; for every mass of foliage has a dark shadow beneath it, forming a more appreciable contrast on account of the intense brilliancy, without glitter, caused by the illumination of every leaf by the sunlight shining through it. Under these circumstances we can once more distinguish species, to some extent, by their colors. We shall soon discover that trees which have a thin corrugated leaf, without gloss, make the most brilliant spectacle when viewed in this manner. Nothing can surpass the foliage of the elm, the lime, the maple, and the birch in this peculiar splendor. But trees like the poplar, the tulip-tree, the oak, and the willow, having a leaf of a firmer texture and less diaphanous, look comparatively dull under the same circumstances.

I would repeat that the true summer phase of wood-scenery is that which succeeds the flowering of the forest, when all the different greens have faded into one dark shade of verdure. There is no longer that marked and beautiful variety which is displayed before the maturity of the leaves. Summer is not, therefore, the painter’s season. It is dull and tame compared even with winter, when regarded as a subject for the brush or the pencil, and especially when compared with spring and autumn. Summer is the time for the observations of the botanist, not for those of the picturesque rambler; for beneath this sylvan mass of monotonous verdure the sods are covered with an endless variety of herbs and flowers, surpassing in beauty those of any other season.

THE OAK.

If the willow be the most poetical of trees, the Oak is certainly the most useful; though, indeed, it is far from being unattended with poetic interest, since the ancient superstitions associated with it have given it an important place in legendary lore. It is not surprising, when we remember the numerous benefits conferred on mankind by the Oak, that this tree has always been regarded with veneration, that the ancients held it sacred to Jupiter, and that divine honors were paid to it by our Celtic ancestors. The Romans, who crowned their heroes with green Oak leaves, entitled the “Civic Crown,” and the Druids, who offered sacrifice under this tree, were actuated by the same estimation of its pre-eminent utility to the human race. When we consider the sturdy form of the Oak, the wide spread of its lower branches, that symbolize protection; the value of its fruit for the sustenance of certain animals; and the many purposes to which the bark, the wood, and even the excrescences of this tree may be applied,—we can easily understand why it is called the emblem of hospitality. The ancient Romans planted it to overshadow the temple of Jupiter; and in the adjoining grove of oaks,—the sacred grove of Dodona,—they sought those oracular responses which were prophetic of the result of any important adventure.
