The Silver Fir is indigenous to the mountains of Central Europe, and to the west and north of Asia, rising to the commencement of the zone of the Scotch fir. It is found in France, on the Pyrenees, the Alps, and the Vosges; in Italy, Spain, Greece, and the south of Germany; also in Russia and Siberia; but it is not found indigenous in Britain or Ireland. On the Carpathian mountains it is found to the height of 3200 feet; and on the Alps, to the height of from 3000 to 4000 feet. Wherever it is found of a large size, as in the neighbourhood of Strasburg, and in the Vosges, where it has attained the height of one hundred and fifty feet, it invariably grows in good soil, and in a situation sheltered rather than exposed. It appears to have been introduced into England about the commencement of the seventeenth century; as we learn from Evelyn, that in 1663 there were two Silver Firs growing at Harefield, Middlesex, which were there planted sixty years before, at two years' growth from the seed, the larger of which had risen to the height of 81 feet, and was 13 feet in girth below; and it was calculated that it contained 146 feet of good timber.

In full-grown trees, the trunk of the Silver Fir is from six to eight feet in diameter, covered, till its fortieth or fiftieth year, with a whitish-gray bark, tolerably smooth; but, as it increases in age, it becomes cracked and chapped. At a still greater age, the bark begins to scale off in large pieces, leaving the trunk of a dark brown colour beneath. The branches stand out horizontally, as do the branchlets and spray, with reference to the main stem of the branch. The leaves on young trees are distinctly two-rowed, and the general surface of the rows is flat; but, as the tree advances in age, and especially on cone-bearing shoots, the disposition of the leaves is less perfect. In every stage of growth they are turned up at the points; but more especially so on old trees, and on cone-bearing branches. The leaves are shorter and broader, and are set much thicker on the spray, than those of other firs and pines. The upper surface of the leaves is also of a darker and brighter green, while underneath they have two white silvery lines running lengthwise on each side of the midrib, which make a conspicuous appearance on the partially turned up leaves; whence its name. The cones of the Silver Fir are large and cylindrical, being from six to eight inches long, erect, and bluntly pointed at both ends. When young they are green, but, as they advance to maturity, the scales acquire a rich purplish colour, and when quite ripe are deep brown; they remain upwards of a year upon the tree, as they first appear in May, when they blossom, and do not ripen the seed till October of the following year. The scales are large, with a long dorsal bract, and fall from the axillar spindle of the cone in the spring of the second year. The seeds are irregular and angular, with a large membranaceous wing. Cones with fertile seeds are seldom produced before the tree has attained its fortieth year; though without, seeds often appear before half that period has elapsed.

Gilpin remarks that "the Silver Fir has very little to boast in point of picturesque beauty. It has all the regularity of the spruce, but without its floating foliage. There is a sort of harsh, stiff, unbending formality in the stem, the branches, and the whole economy of the tree, which makes it disagreeable. We rarely see it, even in its happiest state, assume a picturesque shape." In this opinion Sir T. D. Lauder does not entirely coincide, for, in his remarks upon Gilpin's text, he says, "As to the picturesque effect of this tree, we have seen many of them throw out branches from near the very root, that twined and swept away from them in so bold a manner, as to give them, in a very great degree, that character which is most capable of engaging the interest of the artist."

The rate of growth of the Silver Fir is slow when young, but rapid after it has attained the age of ten or twelve years. In England, under advantageous circumstances, it attains a magnificent size, some recorded trees being from 100 to 130 feet in height, with trunks varying in diameter from three to six feet, and containing from two hundred to upwards of three hundred feet of timber. In Scotland, also, it has reached dimensions equally great. At Roseneath Castle, Argyleshire, there are two Silver Firs which Sir T. D. Lauder considered the finest specimens he had ever seen. When measured in 1817, he says, "the circumference of one of them, at five feet from the ground, was fifteen feet nine inches; at three feet from the ground, it was seventeen feet six inches; and just above the roots, it was nineteen feet eight inches. The second tree was sixteen feet two inches in girth at five feet from the ground; seventeen feet eleven inches at three feet from the ground; and nineteen feet ten inches when measured immediately above the roots." The Silver Fir likewise grows to a large size in Ireland, much more rapidly than any other tree. Some planted in a wet clay, on a rock, have measured twelve feet in girth at the base, and seven feet six inches at five feet high, after a growth of forty years.

THE NORWAY SPRUCE.

Generic characters. Flowers monoecious. Barren catkins crowded, racemose. Scales of the cone thinned away to the edge, and usually membranous or coriaceous. Leaves never fascicled.

Though a native of the mountains of Europe and Asia in similar parallels of latitude, the Spruce Fir is not considered indigenous to Britain. It must, however, have been introduced at an early period, as it is mentioned by our oldest writers on arboriculture. It is most common in Lapland, Norway, Sweden, Denmark, and throughout the north of Germany. It grows in the south of Norway at an elevation of 3000 feet above the level of the sea, and in the north on mountains in 70° N. lat. at 750 feet. In the valleys of the Swiss Alps, the Spruce is frequently found above one hundred and fifty feet in height, with trunks from four to five feet in diameter. This tree requires a soft moist soil. Among dry rocks and stones, where the Scotch fir would flourish, the Spruce Fir will scarcely grow.

The Norway Spruce Fir is the loftiest of European trees, attaining, in favourable situations, the enormous height of one hundred and eighty feet; with a very straight upright trunk, from two to six feet in diameter, and widely extending branches, which spread out regularly on every side, so as to form a cone-like or pyramidal shape, terminating in a straight arrow-like leading shoot. In young trees, the branches are disposed in regular whorls from the base to the summit; but in old trees the lower branches drop off. The trunk is covered with a thin bark, of a reddish colour and scaly surface, with occasional warts or small excrescences distributed over its surface. The leaves are solitary, of a dark grassy green, generally under one inch in length, straight, stiff, and sharp-pointed, disposed around the shoots, and more crowded together laterally than on the upper and under sides of the branchlets. The barren flowers, about one inch long, are cylindrical, on long catkins, curved, of a yellowish colour, with red tips, and discharging, when expanded, a profusion of yellow pollen. The fertile flowers are produced at the ends of the branches, first appearing as small pointed purplish-red catkins; they afterwards gradually assume the cone-like form, and become pendant, changing first into a green and latterly into a reddish brown, acquiring a length of from five to seven inches, and a breadth of above two inches. The scales are rhomboidal, slightly incurved, and rugged or toothed at the tip, with two seeds in each scale. The seeds, which are very small, and furnished with large membranous wings, are not shed till the spring of the second year.

As an ornamental tree, all admirers of regularity and symmetry are generally partial to the Spruce. Gilpin was, however, no great admirer of the tree; but still he allows it to have had its peculiar beauties. "The Spruce Fir," he says, "is generally esteemed a more elegant tree than the Scotch pine; and the reason, I suppose, is because it often feathers to the ground, and grows in a more exact and regular shape: but this is a principal objection to it. It often wants both form and beauty. We admire its floating foliage, in which it sometimes exceeds all other trees; but it is rather disagreeable to see a repetition of these feathery strata, beautiful as they are, reared tier above tier, in regular order, from the bottom of a tree to the top. Its perpendicular stem, also, which has seldom any lineal variety, makes the appearance of the tree still more formal. It is not always, however, that the Spruce Fir grows with so much regularity. Sometimes a lateral branch, here and there taking the lead beyond the rest, breaks somewhat through the order commonly observed, and forms a few chasms, which have a good effect. When this is the case, the Spruce Fir ranks among picturesque trees. Sometimes it has as good an effect, and in many circumstances a better, when the contrast appears still stronger; when the tree is shattered by some accident, has lost many of its branches, and is scathed and ragged. A feathery branch, here and there, among broken stems, has often an admirable effect; but it must arise from some particular situation. In all circumstances, however, the Spruce Fir appears best either as a single tree, or unmixed with any of its fellows; for neither it, nor any of the spear-headed race, will ever form a beautiful clump without the assistance of other trees."

The Spruce Fir is raised from seed, which should be chosen from healthy vigorous trees. The young plant appears with from seven to nine cotyledons, but makes little progress till after the third year, when it begins to put out lateral branches. Its progress from this time, till its fifth or sixth year, is at the annual rate of about six inches, after which age its annual growth, in favourable soils, is very rapid, the leading shoot being frequently from two to three feet in length, and this increase it continues to support with undiminished vigour for forty or fifty years, many trees within that period attaining a height of from sixty to eighty feet. Its growth after this period is slower, and the duration of the tree, in its native habitats, is considered to range between one hundred and one hundred and fifty years.

THE SYCAMORE, OR GREATER MAPLE.

For the generic characters, see p. 139.

Turner, who wrote in 1551, considered the Sycamore as a stranger, or tree that had been introduced. On the Continent it is spread over the mountains of middle Europe; and is found in Switzerland, where it particularly abounds, growing at an elevation of from 2000 to 3000 feet above the level of the sea, where the soil is dry and of a good quality.

The Sycamore is "certainly a noble tree," vieing, in point of magnitude, with the oak, the ash, and other trees of the first rank. It presents a grand unbroken mass of foliage, contrasting well, in appropriate situations, with trees of a lighter and more airy character. It has round spreading branches, and a smooth ash-coloured bark, frequently broken into patches of different hues, by peeling off in large flakes, like the planes. The leaves have long foot-stalks, are four or five inches broad, palmate, with five acute, unequally serrated lobes; the middle one largest, pale or shining beneath. The flowers are green, the size of a currant blossom, disposed into axillary, pendulous, compound clusters; stamens of the barren flower twice as long as the corolla. Ovary downy, with broad-spreading wings. Selby observes that "from the strength of its spray, and the nature of its growth, which is stiff and angular, the Sycamore is especially calculated to act as a shelter or break-wind in exposed situations, whether it be upon the coast where it braves the cutting eastern blasts, or upon bleak and elevated tracts, subject to long continued and powerful winds; for even in such localities, provided the soil be dry, and of tolerable quality, it attains a respectable size, and shows an upright form, unconquered by the blast. It is, probably, for these peculiar and enduring qualities that we see it so frequently in the north of England and in Scotland planted by itself, or sometimes in company with the ash, around farm houses and cottages, in high and exposed situations." This custom is evidently alluded to by the Westmoreland poet, in his description of the landscape on the banks of the Wye:--

Once again Do I behold these steep and lofty cliffs, That on a wild secluded scene impress Thoughts of more deep seclusion; and connect The landscape with the quiet of the sky. The day is come when I again repose Here, under the dark Sycamore, and view These plots of cottage-ground, these orchard tufts, Which at this season, with their unripe fruits, Are clad in one green hue, and lose themselves Among the woods and copses, nor disturb The wild green landscape. Once again I see These hedge-rows, hardly hedge-rows, little lines Of sportive wood run wild: these pastoral farms Green to the very door; and wreaths of smoke, Sent up, in silence, from among the trees! With some uncertain notice, as might seem Of vagrant dwellers in the houseless woods, Or of some hermit's cave, where by his fire The hermit sits alone. These beauteous forms, Through a long absence, have not been to me As is a landscape to a blind man's eye: But oft, in lonely rooms, and 'mid the din Of towns and cities, I have owed to them, In hours of weariness, sensations sweet, Felt in the blood, and felt along the heart; And passing even into my purer mind, With tranquil restoration:--feelings, too, Of unremembered pleasure: such, perhaps, As have no slight or trivial influence On that best portion of a good man's life, His little, nameless, unremembered acts Of kindness and of love. Nor less, I trust, To them I may have owed another gift, Of aspect more sublime: that blessed mood, In which the burthen of the mystery-- In which the heavy and the weary weight Of all this unintelligible world Is lightened:--that serene and blessed mood, In which the affections gently lead us on, Until the breath of this corporeal frame, And even the motion of our human blood, Almost suspended, we are laid asleep In body, and become a living soul: While with an eye made quiet by the power Of harmony, and the deep power of joy, We see into the life of things. If this Be but a vain belief, yet, O! how oft, In darkness, and amid the many shapes Of joyless daylight; when the fretful stir Unprofitable, and the fever of the world, Have hung upon the beatings of my heart, How oft, in spirit, have I turned to thee, O sylvan Wye! Thou wanderer thro' the woods, How often has my spirit turned to thee!

Wordsworth.

The Sycamore is not unfrequently planted in streets and before houses, on account of its spreading branches and thick shade, for which it bears a high reputation. Of this tree Sir T. D. Lauder says, "the spring tints are rich, tender, glowing, and harmonious. In summer, its deep green hue accords well with its grand and massy form; and the browns and dingy reds of its autumnal tints harmonize well with the other colours of the mixed grove, to which they give a depth of tone. It is a favourite Scotch tree, having been much planted about old aristocratic residences in Scotland."

The Sycamore, in the language of flowers, signifies curiosity, because it was supposed to be the "tree on which Zaccheus climbed to see Christ pass on his way to Jerusalem, when the people strewed leaves and branches of palm and other trees in his way, exclaiming, 'Hosanna to the Son of David!' The tree which is frequently called the Sycamore in the Bible, was not the species under description, A. pseudo-platanus, but a species of fig, Ficus sycomorus, a native of Egypt, where it is a timber-tree exceeding the middle size, and bearing edible fruit."

The common Sycamore is generally propagated by seed; and its varieties by layers, or by budding or grafting. It will also propagate freely by cuttings of the roots. It is a tree of rapid growth, frequently attaining a diameter of from four to five inches in twenty years. It arrives at its full growth in fifty or sixty years; but it requires to be eighty or one hundred years old before its wood arrives at perfection. It produces fertile seeds at the age of twenty years, but flowers several years sooner. The longevity of the tree is from one hundred and forty to two hundred years, though it has been known of a much greater age. There are many fine Sycamores in different parts of the kingdom; the largest of which, one at Bishopton in Renfrewshire, is sixty feet in height and twenty feet in girth. This tree is known to have been planted before the Reformation, and is therefore more than three hundred years old, yet it has the appearance of being perfectly sound.

THE COMMON WALNUT TREE.

Generic characters. Flowers monoecious. Stamens 18 to 24. Drupe with a 2-valved deciduous sarcocarp, or rind; and a deeply-wrinkled putamen or shell.

The Walnut tree is a native of Persia, and is found growing wild in the North of China. It was known to the Greeks and Romans, and was probably introduced into this country by the latter. It is now to be met with in every part of Europe, as far north as Warsaw; but it is nowhere so far naturalized as to produce itself spontaneously from seed. It ripens its fruit, in fine seasons, in the neighbourhood of Edinburgh, as a standard; and it lives against a wall as far north as Dunrobin Castle, in Sutherlandshire.

The Walnut forms a large and lofty tree, with strong spreading branches, attaining even in this country to the height of ninety feet. The leaves have three or four pairs of oval leaflets, terminated by an odd one, which is longer than the rest. The barren catkins are pendulous, and are produced near the points of the shoots. The bark is thick and deeply furrowed on the trunk; but on the upper branches it is gray and smooth. The fruit is green and oval; and, in the wild species, contains a small hard nut. In the most esteemed cultivated varieties, the fruit is of a roundish oval, and is strongly odoriferous; nearly two inches long, and one and a half broad. The nut occupies two-thirds of the volume of the fruit. Towards autumn the husk softens, and, decaying from about the nut, allows it to fall out.

The nuts are used in different ways, and at various stages of their growth; when young and green, and before the shells become indurated, they make an excellent and well-known pickle, as well as a savoury kind of ketchup, and a liqueur is also made from them in this state. Previous to their becoming fully ripe, and while the kernel is yet soft, they are eaten in France with a seasoning of salt, pepper, vinegar, and shallots. When fully ripe, they are both wholesome and easy of digestion, so long as they remain fresh, and part freely from the pellicle, or skin, which envelopes the kernel. An oil is expressed from the nuts, which is of great service to the artist in whites, and other colours, and also for gold size and varnish.

When Walnuts are plentiful, it has been observed that there is also a plentiful harvest. Virgil mentions this observation in the first of his Georgics, which is thus translated by Martyn:--"Observe also when the Walnut tree shall put on its bloom plentifully in the woods, and bend down its strong, swelling branches: if it abounds in fruit, you will have a like quantity of corn, and a great threshing with much heat. But if it abounds with a luxuriant shade of leaves, in vain shall your floor thresh the corn, which abounds with nothing but chaff."

The Walnut is far from being an unpicturesque tree, and planted at some distance from each other they form shady and graceful avenues, and prosper well in hedge-rows. The Bergstras (which extends from Heidelberg to Darmstadt) is planted entirely with this tree; for by an ancient law, the Borderers were compelled to plant and train them up, chiefly on account of their ornament and shade, so that a man might ride for miles about that country, under a continued arbour or close walk--the traveller as well refreshed by its fruit as by its shade. Amid other trees whose foliage may be of a vivid green, its warm, russet-hued leaves present a pleasing variety about the end of May; and in summer that variety is still preserved by the contrast of its yellowish hues with the darker tints of other trees. It puts forth its leaves at such an advanced period of the year, and sheds them so early, that it is never long in harmony with the grove. It, therefore, stands best alone, as the premature loss of its foliage is then of less consequence.

The Walnut tree is found abundantly in Burgundy, where it stands in the midst of their corn fields, at distances of sixty and a hundred feet, and is said to be a preserver of the crops by keeping the ground warm. Whenever a tree is felled, which is only when old and decayed, a young one is planted near it; and in Evelyn's time, between Hanau and Frankfort, in Germany, no young farmer was permitted to marry a wife, until he had brought proof that he had planted a stated number of these trees. M. Sorbiere mentions the Dutch plantations of Walnut trees in terms of praise, remarking, that even in the very roads and common highways, they are better preserved and maintained than those about the houses and gardens belonging to the nobility and gentry of most other countries.
