The Hickory is not a round-headed tree; it approaches a cylindrical form, somewhat flattened at the top, but seldom attaining any strict regularity of shape. It does not expand into a full and flowing head, but is often divided into distinct masses of foliage, separated by vacant spaces of considerable size, and presenting an appearance as if a portion of the tree had been artificially removed. These gaps do not extend all round the tree; they are irregularly disposed, some trees having several of them, others none or only one; and they seem to have been caused, when the tree was young, by the dwindling of some principal branch. The Hickory throws out its branches at first very obliquely from the shaft; afterwards the lower ones bend down as the tree increases in size, and acquire an irregular and contorted shape; for, notwithstanding their toughness, they bend easily to the weight of their fruit and foliage.
This tree is celebrated in the United States for the toughness of its wood; and the term Hickory is used as emblematical of a sturdy and vigorous character. It possesses some of the ruggedness, without the breadth and majesty of the Oak, though it exceeds even this tree in braving the force of a tempest. It is one of our most common pasture-trees, and its deep-green foliage makes amends for the general want of comeliness in its outline.
As we are journeying through the older settlements of New England, the melancholy forms of the ill-fated Plane-trees tower above the surrounding objects, and attract our attention not only by their magnitude, but also by the marks of decay which are stamped upon all. This appearance is chiefly remarkable in the early part of summer: for the trees are not dead; but their vitality is so far gone that they are tardy in putting out their leaves, and seldom before July are they fully clad in verdure. When they are not in leaf, we may observe an unnatural growth of slender twigs in tufts at the ends of their branches. This is caused by the failure of the tree in perfecting its wood before the growth of the branches is arrested by the autumnal frosts; and this accident has been repeated annually ever since the trees began to be affected with their malady. The Plane was formerly a very common way-side tree in New England, until the fatality occurred which has caused the greater number of them to perish. It is a fact worthy of notice, that all the trees of this species below the latitude of Long Island have escaped the malady.
The Chenar-tree, or Oriental Plane, is celebrated in history, having had a place in all the public and private grounds of the Greeks and Romans, as well as of the Eastern nations. The American, or Western Plane, called in New England the Buttonwood, is not less remarkable for its size and grandeur. It is one of the loftiest trees, and its lateral branches, being of great length, give it extraordinary breadth. It also runs up to an unusual height, compared with other trees, before it forms a head, so that its lower branches are sometimes elevated above the roofs of the houses of common height Hence it would be a valuable tree for road-sides, if it were healthy, as it would allow the largest vehicles to pass freely under its boughs.
A far more beautiful tree, gracing equally the forest and the way-side, is the Ash, charming our sight with the gracefulness of its proportions in winter, with its flowing drapery of verdure in summer, and its variety of glowing tints in autumn. The Ash has been styled in Europe "the painter's tree,"a fact which is worthy of notice, inasmuch as those writers who have theorized concerning the nature of beauty have generally regarded trees of broken and irregular shapes, like the Hickory, as more picturesque than those of prim and symmetrical habit, like the Ash. The practice of the great masters in painting seems adverse to this idea, since they have introduced the Ash more frequently than other trees into their pictures; and it shows the futility of the attempt to draw a distinction between picturesque and beautiful trees. All trees, indeed, of every natural shape, may be considered picturesque, as, in one situation or another, every species may be introduced to heighten the character of a picture or a landscape.
The Ash never fails to attract attention by the peculiar beauty of its outlines, the regular subdivision of its branches, its fair proportions and equal balance without any disagreeable formality. Nothing can exceed the gracefulness of its pinnate foliage, hanging loosely from its equally divergent spray, easy of motion, but not fluttering, and always harmonizing in its tints with the season of the year. Notwithstanding the different character, in regard to symmetry, of the Ash and the Hickory, the two trees are often mistaken for each other, and, when the latter is evenly formed, it is sometimes difficult at first sight to distinguish it. They differ, however, in all cases, in the opposite arrangement of the leaves and small branches of the Ash, and their alternate arrangement in the Hickory. One of these branches invariably becomes abortive, as the tree increases in size, so that their opposite character is apparent only in the spray.
In wet places which have never been subjected to the plough, in grounds partly inundated a great portion of the year, luxuriating in company with the Northern Cypress, over an undergrowth of Dutch Myrtles and Button-bushes, we find the singular Tupelo-tree. This tree is the opposite of the Ash in all its characteristics. There is no regularity in any part of its growth, and no tree in the forest sports in such a variety of grotesque and fantastic shapes. Sometimes it spreads out its branches horizontally, forming a perfectly flat top, as if it had grown under a platform; again it forms an irregular pyramid, most commonly leaning from an upright position. It has usually no definable shape, often sending out one or two branches greatly beyond the rest, some directed obliquely downwards, others twisted and horizontal. This tree, if it had no other merit, would be prized for its eccentricities; but it is not without beauty. It possesses a fine glossy foliage, unrivalled in its verdure, and every branch is fully clothed with it; and, whatever may be the age of the tree, it never shows the marks of decrepitude.
The pyramidal trees are included chiefly among the coniferous evergreens, embracing the Pine, the Fir, the Spruce, and the Cypress. Though many of the deciduous trees assume more or less of this outline, it is the normal and characteristic form of the Pines and their kindred species. It is a peculiarity of the pyramidal trees, with a few exceptions, to remain always disfigured, after the loss of an important branch, having no power to fill the vacant space by a new growth. Other trees readily fill up a vacancy occasioned by the loss of a branch, and may suffer considerable mutilation without losing their beauty, because an invariable proportion is not necessary to render them pleasing objects of sight. On account of the symmetry of their forms, the pyramidal trees are made ugly by the loss of a limb, as the porch of a temple would be ruined by the removal of one of its pillars. Hence we may understand the charm of that irregularity that prevails in the forms of vegetation. If we remove a branch from an Elm or an Oak, or even from an Ash, we destroy no positive symmetry; it is like removing a stone from a loose stone wall; we do but slightly modify its disproportions.
The White Pine may be selected as the American representative of the pyramidal trees, being the most important as well as the most striking in its appearance. It is a Northern tree, not extending so far south as the region of the Cypress and Magnolia, and attaining perfection only on the northeastern part of the continent. In the New England States, it contributes more than any other species to the beauty of our landscapes, where it is commonly seen in scattered groups, but not often as a solitary standard. We see it in our journeys, projecting over eminences that are skirted by old roads, shading the traveller from the sun and protecting him from the wind. We have sat under its fragrant shade, in our pedestrian tours, when, weary with heat and exercise, we sought its gift of coolness, and blessed it as one of the benign deities of the forest. We are familiar with it in all pleasant and solitary places; and in our afternoon rambles we have listened, underneath its boughs, to the plaintive note of the Green Warbler, who selects it for his abode, and who has caught a melancholy tone from the winds that from immemorial time have tuned to soft music its long sibilant leaves.

The White Pine is a tree that harmonizes with all situations, rude and cultivated, level and abrupt. On the side of the mountain it adds grandeur to the declivity, and gives a look of sweeter tranquillity to the green pastoral meadow. It yields a darker frown to the projecting cliff, and a more awful uncertainty to the mountain-pass or the hollow ravine. Amid desolate scenery it spreads a cheerfulness that detracts nothing from its power over the imagination, while it relieves it of its terrors by presenting a green bulwark to defend us from the elements. Nothing can be more cheerful in scenery than the occasional groups of Pines which have come up spontaneously on the bald hills near our coast, elsewhere a dreary waste of gray rocks, stunted shrubbery, and prostrate Juniper. In the forest the White Pine constitutes the very sanctuary of Nature, its tall pillars extending into the clouds, and its broad canopy of foliage mixing with the vapors that descend in the storm.
Such are its picturesque aspects: but in a figurative light it may be regarded as a true symbol of benevolence. Under its outspread roof, thousands of otherwise unprotected animals, nestling in the bed of dry leaves which it has spread upon the ground, find shelter and repose. The squirrel subsists upon the kernels obtained from its cones; the rabbit browses upon the Trefoil and the spicy foliage of the Hypericum which are protected in its conservatory of shade; and the fawn reposes on its brown couch of leaves, unmolested by the outer tempest. From its green arbors the quails may be roused in midwinter, when they resort thither to find the still sound berries of the Mitchella and the Wintergreen. Nature, indeed, seems to have designed this tree to protect the animal creation, both in summer and winter, and I am persuaded that she has not conferred upon them a more beneficent gift.
As an object of sight, the White Pine is free from some of the defects of the Fir and Spruce, having none of their stiffness of foliage and inflexibility of spray, that cause them to resemble artificial objects. It has the symmetry of the Fir, joined with a certain flowing grace that assimilates it to the deciduous trees. With sufficient amplitude to conceal a look of primness that often arises from symmetry, we observe a certain negligent flowing of its leafy robes that adds to its dignity a grace which is apparent to all. It seems to wear its honors like one who feels no constraint under their burden; and when smitten by a tempest, it bids no defiance to the gale, bending to its wrath, but securely resisting its power.
Of the American coniferous trees, the Hemlock is of the next importance, being, perhaps, in its perfection, a more beautiful tree than the White Pine, or than any other known evergreen. It is far less formal in its shape than other trees of the same family. Its branches, being slender and flexible, do not project stiffly from the shaft; they bend slightly at their terminations, and are easily moved by the wind; and as they are very numerous, and covered with foliage, we behold in the tree a dense mass of glittering verdure, not to be seen in any other tree of the forest.
The Hemlock is unknown as a shade-tree; it is seldom seen by the road-side, except on the edge of a wood, and not often in cultivated grounds. The want of success usually attending the transplantation of it from the woods has prevented the general adoption of it as an ornamental tree. The Hemlock, when transplanted from the wood, is almost sure to perish; for Nature will not allow it to be desecrated by any association with Art. She reserves it for her own demesnes; and if you would possess one, you must go to its native spot and plant your garden around it, and take heed, lest, by disturbing its roots, you offend the deity who protects it. Some noble Hemlocks are occasionally seen in rude situations, where the cultivator's art has not interrupted their spontaneous growth; and the poet and the naturalist are inspired with a more pleasing admiration of their beauty, because they have seen them only where the solitary birds sing their wild notes, and where the heart is unmolested by the crowding tumult of human settlements.
The Pitch Pine has neither grace nor elegance, and though it is allied botanically to the pyramidal trees, it approaches the shape of the round-headed trees. There is a singular ruggedness about it; and when bristling all over with the stiff foliage that sometimes covers it from the extremities of the branches down almost to the roots, it cannot fail to attract observation. Trees of this species, for the most part too rough and homely to please the eye, are not generally valued as objects in the landscape; but there is a variety in their shape that makes amends for their want of comeliness, and gives them a marked importance. We do not in general sufficiently appreciate the value of homely objects among the scenes of Nature,which are, indeed, the ground-work of all charming scenery, and set off to advantage the beauty of more comely things. They prepare us, by increasing our susceptibility, to feel more keenly the force of beauty in other objects. They give rest and relief to the eye, after it has experienced the stimulating effects of beautiful forms and colors, which would soon pall upon the sense; and they are interesting to the imagination, by leaving it free to dress the scene with the wreaths of fancy.
It is from these reflections that I have been led to prize many a homely tree as possessing a high value, by exalting the impressions of beauty which we derive from other trees, and by relieving Nature of that monotony which would attend a scene of unexceptional beauty. This monotony is apparent in almost all dressed grounds of considerable extent. We soon become entirely weary of the ever-flowing lines of grace and elegance, and the harmonious blending of forms and colors introduced by art. On the same principle we may explain the difficulty of reading with attention a whole volume on one subject, written in verse. We are soon weary of luxuries; and when we have been strolling in grounds laid out with gaudy flower-beds, the tired eye, when we go out into the fields, rests with serene delight upon rough pastures bounded by stone walls, and hills clothed with lichens and covered with boulders.
The homely Pitch Pine serves this important purpose of relief in the landscapes of Nature. Trees of this species are abundant in sandy levels, in company with the slender and graceful White Birch, "The Lady of the Woods," as the poet Coleridge called it. From these Pines proceed those delightful odors which are wafted to our windows by a mild south wind, not less perceptible in winter than in summer, and which are in a different manner as charming as a beautiful prospect.
