Woodland Gleanings: Being an Account of British Forest-Trees

by Robert Tyas

The clump of trees next occupies our attention. The term, says Gilpin, has rather a relative meaning, as no rule of art hath yet prescribed what number of trees form a clump. Near the eye we should call three or four trees a clump, and at the same time, in distant or extensive scenery, we should apply the same term to any smaller detached portion of wood, though it may be formed of hundreds of trees. But though the term admits not of exact definition, we will endeavour to make the ideas contained under it as distinct as possible.

We distinguish, then, two kinds of clumps, the smaller and the larger; confining the former chiefly to the foreground, and considering the latter as a distant ornament.

With respect to the former, we apprehend its chief beauty arises from contrast in the parts. We shall attempt to enumerate some of the sources whence the beauty of contrast is produced. Three trees, or more, standing in a line, are formal, but in the natural wood this formality is rarely found. And yet even three trees in a line will be greatly assisted by the lines of the several trunks taking different directions; and by the various forms, distances, and growth of the trees.

If three trees do not stand in a line, they must of course stand in a triangle, which produces a great variety of pleasing forms. And if a fourth tree be added, it stands beautifully near the middle of the triangle, of whatever form the triangle may be. If the clump consist of more trees than four, a still greater variety among the stems will of course take place; double triangles, and other pleasing shapes, all of which may be seen exemplified in every wood of natural growth.

The branches are not less the source of contrast than the stem. To be picturesque, they must intermingle with each other without heaviness; they must hang loosely, but yet with varied looseness on every side; and if there be one head or top of the tree above another, there may be two or three subordinate, according to the size of the clump.

Different kinds of trees, in the same clump, often occasion a beautiful contrast. There are few trees which will not harmonize with trees of another kind; though it may be that contrasts the most simple and beautiful are produced by the various modes of growth in the same species. Two or three oaks, intermingling their branches together, have often a very pleasing effect. The beech, when fully grown, is commonly (in a luxuriant soil at least), so heavy, that it seldom blends happily, either with its own kind or any other. The silver fir, too, is a very unaccommodating tree, as also all the other firs, and indeed every kind of tree that tapers to a point. The pine race, however, being clump-headed, unite well in composition. With these also the Scotch fir leagues, from little knots of which we often see beautiful contrasts arise. When they are young and luxuriant, especially if any number of them above four or five are planted together, they generally form a heavy murky spot, but as they acquire age this heaviness goes off, the inner branches decay, the outer branches hang loosely and negligently, and the whole has frequently a good effect, unless they have been planted too closely. It may be doubted how far deciduous trees mingle well in a clump with evergreens; and yet, occasionally, from the darkness of the fir contrasting agreeably with the sprightly green of a deciduous tree just coming into leaf, a natural good effect of light and shade is produced.

Contrasts arise, again, from the mixture of trees of unequal growth, from a young tree united with an old one, a stunted tree with a luxuriant one, and sometimes from two or three trees, which in themselves are ill-shaped, but when combined are pleasing. Inequalities of all these kinds are what chiefly give nature's planting a superiority over art.

The form of the foliage is another source of contrast. In one part, where the branches intermingle, the foliage will be interwoven and close; in another, where the boughs of each tree hang separately, the appearance will be light and easy.

But whatever beauty these contrasts exhibit, the effect is altogether lost if the clump be not well balanced. If no side preponderate so as to offend the eye, it is enough, and unless the clump have sustained some external injury, it is seldom deficient in point of balance. Nature generally conducts the stems and branches in such easy forms, wherever there is an opening, and fills up all with such nice contrivance, and with so much picturesque irregularity, that we rarely wish for an amendment in her works. So true is this, that you may not take away a tree from a clump without infallibly destroying the balance which can never again be restored.

When the clump grows larger, it becomes qualified only as a remote object, combining with vast woods, and forming a part of some extensive scene, either as a first, a second, or a third distance.
