CLASSIFIED INDEX TO NATURAL ORDERS, GENERA AND SPECIES Described in this work.
PREFACE.
The purpose of this volume is not the addition of one more to the numerous treatises upon sylviculture or forestry, but to afford a straightforward means for the identification of our native trees and larger shrubs for the convenience of the rural rambler and Nature-lover. The list of British arborescent plants is a somewhat meagre one, but all that could be done in a pocket volume by way of supplementing it has been done—by adding some account of those exotics that have long been naturalized in our woods, and a few of more recent introduction that have already become conspicuous ornaments in many public and private parks.
In this edition forty-eight extra plates have been added, of which twenty-four are in colours. The latter are in part reproductions of water-colour studies of flowers and fruits, and partly from photographs by a new method. For the black and white plates, the photographs, it should be explained, have been taken upon a novel plan in most cases. This consists in photographing a deciduous tree in its summer glory, and returning to the same spot in winter and photographing the same individual, so that a striking comparison may be made between the summer and winter aspects of the principal species. Supplementary photographs are given, in many cases, of the bole, which exhibit the character of the bark, and should prove a valuable aid in the identification of species. Others show in larger detail the flowers or fruit, and the characteristic leaf-buds in spring.
The figures in the text have all been expressly drawn for the work with a view to showing at a glance the general character of the foliage, and in most cases the flower and fruit.
The work is divided into two sections. Part I. including those species that are generally considered to be indigenous to the British Islands, with briefer notices of the introduced species that are closely related to them. Part II. being devoted to those of foreign origin, some of them introduced so long ago that they are commonly regarded as native by those who are not botanists.
INTRODUCTORY.
There are two points of view from which to regard trees—the mercantile and the æsthetic. The former is well exemplified in Dumbiedyke's advice to Jock: "Jock, when ye hae naething else to do, ye may be aye sticking in a tree; it will be growing, Jock, when ye're sleeping." The canny Scot was thinking of the "unearned increment" another generation might gather in, due to the almost unceasing activity of the vegetable cells in the manufacture of timber. The other view was expressed by "the Autocrat of the Breakfast-table" in a letter to a friend: "Whenever we plant a tree we are doing what we can to make our planet a more wholesome and happier dwelling-place for those who come after us, if not for ourselves." But, after all, it is the trees that have been planted by Nature that give the greatest pleasure apart from commercial considerations—the lonely Pine, that grows in rugged grandeur on the edge of the escarpment where its seed was planted in the crevice by the wind; the Oak that grows outside the forest, where a squirrel or a jay dropped the acorn, and where the young tree had room all its life to throw out its arms as it would; the little cluster of Birches that springs from the ferns and moss of the hillside. All trees so grown develop an individuality that is not apparent in their fellows of the timber forest; and however we may delight in the peace and quiet of the forest, with its softened light and cool fragrant air, we can there only regard the trees in a mass. We might, indeed, reverse the old saying, and declare that we cannot see the trees on account of the wood.
Nature and the timber-producer have different aims and pursue different methods in the making of forests, though the latter is not above taking a hint from the former occasionally. Nature mixes her seeds and sows them broadcast over the land she intends to turn into forest, that the more vigorous kinds may act as nurses, sheltering and protecting the less robust. Then comes the struggle for existence, with its final ending in the survival of the fittest. In the mean time the mixed forest has given shelter to an enormous population of smaller fry—plants, mammals, birds, and insects—and has been a delightful recreation ground for man. The timber-producer aims at so controlling the struggle for existence that the survival of the fit is maintained from start to finish. He plants his young trees in regular order, putting in nurses at intervals and along the borders, intending to cut them down when his purpose has been served. The timber trees are allowed no elbow-room, the putting forth of lateral branches is discouraged, but steady upward growth and the production of "canopy" is abetted. His aim is to get these timber-sticks as near alike as possible, free from individuality, and with the minimum of difference in girth at top and bottom of each pole. This means a thicker and longer balk of clean timber when the tree is felled and squared. The continuous canopy induces growth in the upward direction only, and discourages the weeds and undergrowth that add to the charm of the forest, but which unprofitably use up the wood-producing elements in the soil. This plan contrasts strongly with the views on planting formerly prevalent in this country, John Evelyn, for example, making a special point of giving the Oak room to stretch out its arms, "free from all incumbrances." But, then, unlike the timber-producers, Evelyn had an eye for landscape beauty, and giving an opportunity for the display of such beauty. He says: "And if thus his Majesty's forests and chases were stored, viz. with this spreading tree at handsome intervals, by which grazing might be improved for the feeding of deer and cattle under them (for such was the old Saltus), being only visited with the gleams of the sun, and adorned with the distant landscapes appearing through the glades and frequent valleys, nothing could be more ravishing."
The greater the success of the forester, the more profound is the solemn stillness of the forest—and the more monotonous. In place of the natural forest, with its varied and teeming life, we have what Wordsworth called a timber factory. In the natural forest, with its mixture of many kinds of trees, the undergrowth of shrubs, and carpet of grass and weeds, the stronger trees spread out their arms in all directions, and fritter away (as the scientific forester would say) their wood-producing powers in making much firewood and little valuable timber. But the result is very beautiful, and the nature-lover can wander among it without tiring, and can study without exhausting its treasures. Emerson says: "In the woods is perpetual youth. Within these plantations of God a decorum and sanctity reign, a perennial festival is dressed, and the guest sees not how he should tire of them in a thousand years." To the scientific forester this is all waste land, and he pleads for the "higher culture" being applied to it. With every desire that the natural resources of our country should be properly developed, we do hope that he will not be entirely successful in his efforts, and that a few of the woods and wastes of Nature's own planting may be left for the recreation of the simple folk who have not yet taken to appraising the value of everything by the price it will fetch in the market.
The trees described in this volume are the really wild growths that have lived a natural life; and though many of the photographs are from planted trees, they are such as have been allowed to grow as they would, and show the characteristic branching of the species.
A few words on the life of a tree may be welcomed here by those readers who have not made a study of botany. Although the nurseryman makes use of suckers and cuttings for the quicker multiplication of certain species, every tree in its natural habitat produces seeds and is reproduced by them. The flowering of our forest trees is a phenomenon that does not as a rule attract attention, but their fruiting or seed-bearing becomes patent to all who visit the woods in autumn. A tree has lived many years before it is capable of producing seed. The seed-bearing age is different in each species; thus the Oak begins to bear when it is between sixty and seventy years old, the Ash between forty and
