of the most beautiful forests in high latitudes consist of White Canoe-Birches. We see them in Massachusetts only in occasional groups, but farther north, upon river-banks, they form woods of considerable extent and remarkable beauty; and with their tall shafts, and their smooth white bark, resembling pillars of marble, supporting a canopy of bright green foliage, on a light feathery spray, they constitute one of the picturesque attractions of a Northern tour. Nature seems to indicate the native habitat of this noble tree by causing its exterior to bear the whiteness of snow, and it would be difficult to estimate its importance to the aboriginal inhabitants of Northern latitudes. Yellow Birch woods are not inferior in their attractions: individual trees of this species are often distinguished among other forest timber by extending their feathery summits above the level of the other trees.
The small White Birch is never assembled in large forest groups. Like the Alder, it seems to be employed by Nature for the shading of her living pictures, and for producing those gradations which are the charm of spontaneous wood-scenery. In this part of the continent, a Pitch-Pine wood is commonly fringed with White Birches, and outside of these with a lower growth of Hazels, Cornels, and Vacciniums, uniting them imperceptibly with the herbage of the plain. The importance of this native embroidery is not sufficiently considered by those industrious plodders who are constantly destroying wayside shrubbery, as if it were the pest of the farm,—nor by those "improvers," on the other hand, who wage an eternal warfare against little spontaneous groups of wood, as if they thought everything outside of the forest an intruder, if it was planted by accident, and had not cost money before it was placed there. Give me an old farm, with its stone-walls draped with Poison-Ivy and Glycine, and verdurous with a mixed array of Viburnums, Hazels, and other wild shrubbery, harboring thousands of useful birds, and smiling over the abundant harvests which they surround, before the finest artistical landscape in the world!
Pines are remarkably social in their habit, and cover immense tracts in high latitudes, extending southward, on this continent, as far as the very boundary of the tropics, where they are found side by side with the Dwarf Palm of Florida. But in the region of the true Palms the Pine is wanting. It is worthy of remark, however, that in the fossil vegetation of the Eocene world these two vegetable tribes are found associated. This fact, it seems to me, should be attributed to the mixing of the mountain Pines with the Palms of the sea-level, during that revulsion of Nature by which they were hurled into the same chaotic heap. We are not obliged to infer from their contiguity in these geological remains, that the two species ever flourished together in the same region.
Pine woods possess attractions of a peculiar kind: all lovers of Nature are enraptured with them, and there is a grandeur about them which is felt at once, when we enter them. Their dark verdure, their deep shade, their lofty height, and their branches which are ever mysteriously murmuring, as they are swayed by the wind, render them singularly solemn and sublime. This expression is increased by the hollow reverberating interior of the wood, caused by its clearness and freedom from underbrush. The ground beneath is covered by a matting of fallen leaves, making a smooth brown carpet, that renders a walk within its precincts as comfortable as in a garden. The foliage of the Pine is so hard and durable that in summer we always find the last autumn's crop lying upon the ground in a state of perfect soundness, and under it that of the preceding year only partially decayed. The foliage of two summers, therefore, lies upon the surface, checking the growth of humble vegetation, and permitting only certain species of plants to flourish with vigor.
Mushrooms of various forms and sizes spring out of these decayed leaves, often rivalling the flowers in elegance. Monotropas, uniting some of the habits of the Fungi with the botanical characters of the flowering plants, flourish side by side with the snowy Cypripedium and the singular Coral-Weed. The evergreen Dewberry, a delicate species of Rubus, trails its glossy leaves over the turfs, and mingles its beaded fruit with the scarlet berries of the Mitchella. The Pyrola, named by the Indians Pipsissewa, and regarded by them as a specific for consumption, suspends its pale purple flowers in beautiful umbels, as if to invite the feeble invalid to accept its proffered remedies. Variety, indeed, may be found in these deep shades; but it exists without that profusion which in more favored situations often benumbs our susceptibility to the charms of Nature.
The edging of a Pine wood depends on the character of the soil. The Pitch-Pine, that delights in sandy plains, is embroidered at the North by White Birches; and if a road be cut through a wood of this kind, these graceful trees immediately spring up in abundance by the wayside. If a pond occurs in the middle of a Pine wood, its margin is covered first with low bushes, such as the Andromeda, the Myrica, and the sweet-scented Azalea, then Alders and Willows rise between them and the forest. On the side of the pond that is bounded by high gravelly banks, the margin will be covered by Poplars and Birches. The White Pine, the most noble and the most beautiful tree of the whole coniferous tribe, predominates in the New-England forest; though some wide tracts are covered with the more homely Pitch-Pines, which are the trees that scent the atmosphere on damp still days with their delightful terebinthine odors. The woods in the vicinity of Concord, N.H., on the banks of the Merrimack, known by the poetic appellation of "The Dark Plains", are of this description. In still higher latitudes the dark, majestic Firs become the prevailing timber, and are regarded as typical of sub-arctic regions, where they are accompanied, as if to form a striking and cheerful contrast with their melancholy grandeur, by groups of graceful Birches, and lively, tremulous Poplars.
The Pine-Barrens of the Southern States are celebrated as healthful retreats for the inhabitants of seaport towns, whither they resort in summer for security from the prevailing fevers. They are of a mixed character, consisting of the Northern Pitch-Pine, the Broom-Pine, and the Cypress, intermixed with Red Maples, Sweet Gums, and other deciduous trees. The Pines, however, are the dominant growth: but here they do not grow so compactly as in colder regions, standing widely apart, with a frequent intervening growth of Willows and shrubbery. The sparseness of these woods may be in part attributed to the practice of tapping the trees for their turpentine, which has caused them for a century past to be gradually thinned by consequent decay. Their tall, gaunt forms and almost branchless trunks show that they obtained their principal growth in a dense wood.
The first time I entered one of these Pine-Barrens was some years since, in the month of June, when vegetation was in its prime, before the summer droughts had seared the green herbage, and when the flowering trees and shrubs were in all their glory. During my botanical rambles in the wood, I was struck with the multitude of beautiful flowers in its shady retreats,—seeming the more numerous to me, as I had previously confined my researches to Northern woods. The Phlox grew here in all its native grace and delicacy, where it had never known the fostering hand of Art. Crimson Rhexias, called by the inhabitants Deer-Weed, were distributed among the grassy knolls, like clusters of Picotees. Variegated Passion-Flowers were conspicuous on the bare white sand that checkered the ground, displaying their emblematic forms on their low repent vines, and reminding the wanderer in these almost trackless solitudes of that Faith which was founded on humility and crowned with martyrdom. Here, too, the Spiderwort of our gardens, in a meeker form of beauty and with a paler radiance, luxuriated under the protection of the wood. Already I observed the predominance of luxuriant vines, indicating our nearness to the tropic, wreathed gayly over the tall and branchless trunks of the trees: some, like the Bignonia, in a full blaze of crimson; others, like the Climbing Fern, draping the trees in continual verdure.
These Pines constitute a great part of the timber of the flat country between the mountains and the coast, and render a journey through that region singularly monotonous and gloomy. In the low grounds, a considerable proportion of the wood consists of the Southern Cypress, a graceful and magnificent tree, whose appearance would be very lively and cheerful, were it not for the abundance of long trailing "moss" (usnea) that hangs, like funereal drapery, from its branches, and darkens the whole forest. This parasitic appendant wreathes the woods sometimes almost in darkness, especially in those immense tracts on the borders of the Mexican Gulf that consist entirely of Cypress. There it has been poetically styled the "Garlands of Death," as significant of the fevers that prevail wherever it is abundant.
It is remarkable that the two extremes of climate are distinguished by the predominance of evergreens in their vegetation. Thus, the acicular-leaved trees, consisting of Pines and their congeners, mark the cold-temperate and sub-arctic zones, in north latitude,—while
