Wayside and Woodland Trees Part 6

In the pre-gunpowder era, so important was it to have a sufficient supply of suitable wood for the making of the dreaded English long-bow, that the culture of the Yew was made the subject of a number of royal ordinances, which, of course, were allowed to drop out of observance when the bow was displaced by the firearm. And now when men plant Yews they are mostly the ornamental varieties, such as the Irish or Florence Court Yew, which originated as a wild sport on the mountains of Fermanagh about a hundred and forty years ago. Evelyn, it is true, revived the interest in the Yew as an ornamental tree, and it is with regret we add that at his suggestion it was first put to the base use called topiary work, which had hitherto been restricted to Box and Juniper. Evelyn showed how much more closely and continuously the Yew could be clipped without affecting its vitality, and the fashion he thus set--and regarded as a "merit"--was very generally followed during the next century. Many of the atrocities of those days are still with us, but only as survivals; and we can so often agree with Evelyn that we may forgive him for having led our ancestors astray in this matter. Evelyn was by no means blind to the good points of the tree in its natural condition, as witness this quotation, which is as true to-day as when it was written:--

"He that in winter should behold some of our highest hills in Surry clad with whole woods of these two last sorts of trees [Box and Yew], for divers miles in circuit (as in those delicious groves of them, belonging to the Honourable, my n.o.ble Friend, the late Sir Adam Brown, of Bechworth Castle), from Box Hill, might, without the least violence to his imagination, easily fancy himself transported into some new or enchanted country; for if in any spot in England,

'tis here Eternal spring and summer all the year."

Along the chalk range of which the celebrated Box Hill forms part will be found many fine examples of the Yew, as at Cherkley Court, near Leatherhead, where there is an actual Yew forest. There was a monstrous Yew at Brabourne in Kent, in Evelyn's time, for he tells us he measured it, and found its girth to be only one inch short of fifty-nine feet.

There are numerous giants of the species still living in quiet country churchyards, where they have probably served--as tradition states of those at Fountains Abbey--as a shelter for the builders of the ancient church during its erection. It is reputed to be the longest-lived of all trees, and it is to be hoped that no hindrance will be put in the way of these connections of the present with the far past living to their full natural limit, whatever it may be. It is naturally a tree of the uplands and lower hills, and shows a distinct preference for soils that contain plenty of lime.

The Irish Yew (var. _fastigiata_), to which pa.s.sing reference was made, differs from the type in having all its branches growing erectly, after the manner of a Lombardy Poplar, and in the leaves being scattered promiscuously over the branchlets instead of being in two regular rows.

It attains a height of twenty to twenty-five feet.

The Juniper (_Juniperus communis_) is seldom more than a shrub a few feet in height, though it occasionally develops into a small tree from ten to twenty feet high, and with a girth of five feet. It has a fibrous red bark, which flakes off like that of the Yew. The leaves are shaped like a cobbler's awl, rigid, and end in sharp points. They have thickened margins, the concave upper sides are glaucous, and they are arranged round the branches in whorls of three. The male and female flowers are on separate trees. The male catkin may be known in May by its numerous anthers and pale yellow pollen. The female catkins will be found in the axils of the leaves, and resemble buds. The scales are fleshy, and after fertilization the upper ones slowly develop into the form of a berry, which has a few undeveloped scales at its base. They do not ripen until the following year, when they are blue-black, covered with a fine glaucous bloom. They have a pungent flavour, which is utilized in concocting gin, which indeed owes its name to this fact--the word being merely a contraction of _genevrier_, the French form of Juniper. The "berries" have long been known as a kidney stimulant--a fact which has been fully utilized as the justification of every gin-drinker. A beautiful little moth--_Hypsilophus marginellus_--may often be taken about the Juniper, upon which its caterpillar feeds.

To appreciate the variety of forms a.s.sumed by the Juniper according to the elevation at which it grows, it should be seen on slopes like those of the North Downs in Surrey--one portion of the range at Mickleham is named Juniper Hill. In the valleys it may be found as a small shapely tree, higher up the slopes as a pyramidal shrub, and as we reach higher and more exposed positions, the Juniper gradually dwindles to a low, shapeless bush. This, however, must not be confounded with a distinct variety to which the name _nana_ has been applied; it differs from the type in having shorter and broader overlapping leaves, with curved tips.

Var. _nana_ is confined to the mountains of the north of our islands, and ascends to 2700 feet, which is 300 feet higher than is recorded of the type.

The Virginian Juniper (_Juniperus virginiana_), or "Red Cedar," as it is called on the American continent, is a much larger plant, which is frequently planted in our parks and gardens. It varies in habit, and may be low and spreading, bush-like, or tall and tapering, thirty to forty feet high. Its leaves are in threes, like those of our native species, but the three are united by their bases. It is with the red heart-wood of this tree that our "cedar" pencils are covered, large quant.i.ties of the timber of _J. virginiana_, and formerly of _J. bermudiana_, being imported for the purpose. The Virginian Juniper has been with us for many years. It is mentioned by Evelyn in his "Sylva" (1664), and is believed to have been introduced by him from North America.

[Ill.u.s.tration: _Pl. 78._ Scots Pine.]

[Ill.u.s.tration: _Pl. 79._ Bole of Scots Pine.]

The Scots Pine (_Pinus sylvestris_), commonly but incorrectly styled Scotch Fir, is the typical Pine-tree of Northern Europe, where (especially in Russia and Northern Germany) it const.i.tutes huge forests.

It is even said to cover far wider tracts of country than any other forest tree. Although there is evidence that in ancient days it was pretty widely distributed over Britain, to-day all those Pine-woods of Southern England are the results of planting, and it is only in a few places between Yorkshire and Sutherland, and in Ireland, that it can be regarded as truly wild and indigenous. Mr. John Nisbet points out that the term "pine-forest" is a bit of tautology, for the old German word _forst_ was derived from _foraha_--now represented by _fohre_, a fire or pine--so that "pine-forest" is equivalent to "pine-pine." However, the etymologists will probably allow us to speak of Pine-woods, and we will try to remember that when we use the word forest it must always indicate an a.s.semblage of Pine-trees.

In favourable soil, at a moderate elevation, the Scots Pine is a fine tree a hundred feet high, with a rough-barked trunk, whose girth is twelve feet. Under such conditions it develops a strong tap-root, which goes deep; but where the soil is shallow or otherwise unfavourable the tap-root is not developed. At great elevations the upward growth is checked early, and it becomes a mere evergreen bush. The branches are short and spreading, those on the lower portions of the trunk dying early, so that the tree soon gets that gaunt weather-beaten look that is so characteristic of it. Then, after the growth of the leading shoot has become feeble, the upper branches continue to lengthen, and so bring about that flat-topped condition. Its growth is rapid, and in twenty years it will attain a height of forty or fifty feet.

The leaves, which are in bundles of two, are from two to three inches long, very slender, grooved above and convex beneath. They remain on the tree for over two years, and in their first season are of a glaucous hue, but in the second year this changes to dark deep-green. Both male and female flowers are borne by the same tree. The male catkins are individually small ( inch), but are combined in spikes; this and the abundant pale yellow pollen makes them conspicuous. The female cones are somewhat egg-shaped, tapering to a point, which is often curved. They are usually in cl.u.s.ters of three, and grow to a length of two or three inches. The scales are comparatively few, and their ends are thickened into an irregular four-sided boss, at first ending in a little point.

The seeds are winged, and contained beneath the scales. They take about eighteen months to ripen, when the scales separate in dry windy weather, and allow the breeze to pick out the seeds and send them flying through the air to a great distance. The pollen, too, it should be noted, is of a form specially fitted for aerial transport, each particle of pollen forming two connected spheres. It is quite a common experience in May to find little heaps of this pollen collected in hollows and at the margins of ponds in the neighbourhood of Pine-woods; but, so difficult is it to get people to understand the common facts of nature, that it is generally regarded as evidence of a shower of brimstone having fallen.

It is not only the ignorant rustic who falls into this error; judging from letters sent to the press by country parsons, even the universities fail to prepare their alumni to deal with such phenomena. After the eruptions of La Soufriere, several wrote to say that quant.i.ties of powdered sulphur from St. Vincent had descended in their Surrey and Hampshire parishes! their notion being that the commercial "flowers of sulphur" are the direct produce of volcanoes.

[Ill.u.s.tration: Scots Pine.]

Although the wood produced by the Scots Pine in this country is not considered of the highest quality, the species is certainly of equal value as a timber-producer with any other tree. Owing to our mild winters and long periods of seasonal growth, the Pine-wood produced in Britain is coa.r.s.e-grained and not very durable. In the colder parts of Northern Europe, where summers are short and the long winters are severe, the texture of the timber is more solid and the grain closer.

And so enormous quant.i.ties of Pine-wood come to us from the Baltic ports every year. In addition to the timber, other valuable substances known to commerce are products of the Scots Pine--pitch and tar, resin and turpentine, for example. The Pine is an accommodating tree, for though it likes a deep soil in which to strike its tap-root, it will grow upon rocky ground, where the roots have to become horizontal and near the surface; or it will form forests on poor sandy soils, even on the loose hot sands near the seash.o.r.e. This is a valuable power, because the fall of its needles gradually forms a humus, and so provides food for other plants which could not exist on raw sand.

Other coniferous trees that have become more or less familiar in our plantations and parks will be found in the second division of this book.

The Holly (_Ilex aquifolium_).

The Holly must be regarded as one of our small trees, although many specimens attain a height of forty or fifty feet, with a girth of ten or twelve feet. It is well distributed throughout our islands, ascending to a thousand feet, and it is probable that no other tree is so well known, by its foliage at least, as the Holly, or Holm, to give it its ancient name. The word Holm was incorporated by some of our ancestors far back in the name Holmsdale, which still attaches to the stretch of country at the southern foot of the chalk hills in Surrey, and whose proud motto is, "Never wonne, ne never shall." At the western end of the Holmsdale is Holmwood, and still a little further west Holmbury. In these places the Holly still grows bravely, not far from the old home of John Evelyn, who must be thought of whenever we talk of Hollies, though the recollection has to do with Sayes Court, his Thames-side house, where the barbarian Peter wrought such havoc with his cherished Holly-hedge. How Evelyn must have lamented that outrage is indicated in this extract from the "Sylva":--

"Is there under heaven a more glorious and refreshing object of the kind, than an impregnable hedge of about four hundred feet in length, nine feet high, and five in diameter, which I can show in my now ruined gardens at Say's Court (thanks to the Czar of Moscovy) at any time of the year, glittering with its armed and varnished leaves? The taller standards at orderly distance, blushing with their natural coral. It mocks the rudest a.s.saults of the weather, beasts, or hedge-breakers, _et illum nemo impune lacessit_."

[Ill.u.s.tration: _Pl. 81._ Holly.]

[Ill.u.s.tration: Holly.]

The bark of the Holly is smooth and pale-grey in colour. Time out of mind it has been used in the preparation of a viscid substance known as birdlime, which, spread on twigs, holds the feet of small birds.

Respecting the foliage of the Holly, there is little need to say anything, but for uniformity's sake we may note that the leaves are oval in shape, of a leathery consistence, with a firmer margin, running out into long sharp spines. It is a fact worthy of note that when the Holly has attained to a height of ten feet or so, it frequently clothes its upper branches in leaves that have no spines--a circ.u.mstance that Robert Southey sought to explain in his poem "The Holly-tree," on teleological grounds. His second verse, however, contains sufficient explanation of the fact it describes:--

"Below, a circling fence, its leaves are seen Wrinkled and keen; No grazing cattle through their p.r.i.c.kly round Can reach to wound; But, as they grow where nothing is to fear, Smooth and unarm'd the pointless leaves appear."

In some places the young shoots are gathered by the peasants, dried, bruised, and used as a winter cattle-food. No doubt, in the early history of the Holly, cattle found out its good qualities for themselves, and browsed upon the then-unarmed foliage. In self-defence the tree developed spines upon its leaves, and so kept its enemies at a respectful distance. Above the reach of these marauders the production of spines would be a useless waste of material.

[Ill.u.s.tration: _Pl. 82._ Flowers of Holly.]

The flowers of the Holly, though small, are conspicuous by their great number and white colour. They are about a quarter of an inch across, with four petals and four stamens or stigmas. Sometimes flowers with stamens are produced by the same tree that bears flowers with stigmas; but often the male and the female flowers are borne by separate trees, so that the possessor of a Holly that is solely male is sometimes puzzled by the fact that his tree, though covered with blossom, never produces a berry. The fruit is a.n.a.logous in structure to that of the Plum and Cherry, and is technically termed a _drupe_; but instead of the single stone of these fruits, in the Holly-berry there are four bony little stones, each with its contained seed. The berries ripen about September, and are then scarlet and glossy, though here and there one finds a tree whose fruit never gets beyond the yellow stage of coloration.

Most parts of the tree have had their uses in medicine; the leaves, for example, being said to have value as a febrifuge, and the berries as a purgative, or in large doses (6 to 8) as an emetic. The smooth bark of large Hollies is often attacked by one of the most striking of our native lichens--_Graphis elegans_--whose black fruiting portions look like a raised cuneiform inscription. The Holly is not greatly subject to the attacks of insects, but many of its leaves will be found to have been tunnelled between the upper and lower skins by the larva of a minute moth, one of the Leaf-miners. It also provides the pabulum for the caterpillar of the Holly-blue b.u.t.terfly (_Lycaena argiolus_). The dead leaves may be examined for the minute p.r.i.c.kly Snail (_Helix aculeata_).

The wood of the Holly has an exceedingly fine grain, due to its slow growth, and it is very hard and white. These qualities make it valuable for many purposes, often as a subst.i.tute for Box-wood, and, when dyed black, in lieu of Ebony.

The Spindle-tree (_Euonymus europaeus_).

The Spindle is right on the borderland between trees and shrubs, for though it will grow into a tree twenty feet high, yet our hedgerow specimens are usually bushlike, and only ten or twelve feet high. Until the autumn the Spindle, we fear, is rarely recognized as such, but gets confused with Buckthorn and Dogwood. In October, however, its quaint fruits have changed to a pale crimson hue, which renders them the most conspicuous feature of a hedgerow--even of one plentifully decorated with scarlet hips and haws and bryony-berries. The unusual tint of the Spindle, and the fact that it swings on a slender stalk, at once mark it out from the rigid-stalked hips and haws.

The trunk of the Spindle is clothed in smooth grey bark. The twigs, which are in pairs, starting from opposite sides of a branch, are four-angled. The shining leaves vary from egg-shaped to lance-shaped, with finely-toothed edges. They are arranged in pairs, and in autumn they change to yellow and red. When bruised they give off a f[oe]tid odour, the juice is acrid, and said to be poisonous--a charge which is laid against the bark, flowers, and seed as well. The small greenish-white flowers are borne in loose cl.u.s.ters, of the type known as cymes, from the axils of the leaves, and appear in May and June. Some contain both stamens and pistil, but others are either stamenate _or_ pistillate. The calyx is cut into four or six parts, the petals and stamens agree with these parts in number, but the lobes of the stigma only range from three to five, corresponding with the cells of the ovary. The fruit is deeply lobed, and marked with grooves, indicating the lines of future division, when the lobes open and disclose the seeds, at first covered with their orange jackets, or _arils_, after the manner of the mace that encloses the nutmeg.

The hardness and toughness of Spindle-wood has long been esteemed in the fashioning of small wares where these qualities are essential, and the common name is a survival of the days when spinning was the occupation of every woman. Then spindles were in demand for winding the spun thread upon, and no wood was more suitable than that of Euonymus for making them. It shares with the Cornel (_Cornus sanguinea_) the name Dogwood; it is also Skewerwood, p.r.i.c.kwood, and Pegwood, all suggestive of uses to which it is or was applied. The young shoots make a very fine charcoal for artists' use.

The Spindle is indigenous throughout our islands, but cannot be said to be generally common; it is rarer in Scotland and Ireland than in England.
