![]() It is a feature of a well-grown tree that the extremity of each main bough is terminated by a straight line, and a number of these lines go to the building up of the outline shapes. Again, a Larch no longer remains feathered from tip to base as it grows older, but retains merely the upper part of the cone supported by an immense bare trunk. ![]() Some trees in their old age take a totally differentįorm to that of their younger days-the Scots Pine or Stone Pine, for instance, is cone-shaped when young (then spaces of sky are visible cutting in from the outline to the trunk between the tiers of branches) in its old age it might be caricatured as an umbrella since all but the upper boughs have decayed, leaving a bare trunk. Elsewhere they might seem unbalanced-might seem to be leaning over and sheltering nothing we want the road or bridle path to which they are so harmoniously related.Įffect of old age. Trees overhanging a roadway are always pleasing, for their pose accords with their position, and the trunk and lower boughs continue the curved lines of the shelving banks and road. Until they meet one another and form those delightful arches of living green through which the road winds. Trees that fringe the roadway find elbow-room above it If a tree is crowded on one side, it always makes good use of vacant space on the other. The old stools in the copses of Spanish Chestnut, Oak, and Hazel, though cropped every seven years, yet make a fresh start, and the same season may give forth shoots of four or five feet. While logs of Elm ready for firewood will sometimes break into leaf. Stacks of Withies are often seen with their buttends in water peppered over with fresh young green, Large poles of Willow are so tenacious of life that, if planted, they will sometimes form roots-just as a small cutting would-and become before long promising young trees. normally would be to bear them at perhaps half that angle. A tree overblown can often exist by the few unsevered roots left to it, and can put forth new vertical shoots at right angles to the stem, though its habit. Trees easily adapt themselves to positions a chance seed dropped on a rock will find nourishment among the moss, and the roots- gripping with a tenacious hold the uneven surface of the stone and pushing their way into the crevices-will reach in time the soil and the tree will flourish in spite of such a precarious start in life. It is common knowledge that trees have-like all other vegetation-a preference for certain soils, and develop fine or poor specimens in relation to how they are suited but it may not have been generally noticed that a wet or dry site has a distinct influence on the colouring of the leaves in autumn. But if an exposed position is a calamity for sonic trees, it is life to others we find the frail-looking Birch luxuriating in high positions and withstanding the severest cold in fact, I understand it is the only species of tree in Greenland, and is a common inhabitant of Russia and Siberia, though in the more northern climates it becomes dwarfed to a mere bush. Others seem unable to push their way into the inhospitable space, and remain short in stature and overcrowded with internal forms shorn close by the wind like overgrown bushes matted, dwarfed, and constrained. ![]() In an exposed position a solitary tree is likely to grow squat in form, or to become straggling, denuded of many limbs and scanty of foliage. The tall straight trunk would then divide into large boughs at no great height from the ground, and the lateral boughs would spread to some considerable distance from the trunk. Such a tree would present quite a different appearance if grown by itself and permitted to develop naturally. When it has overtopped its neighbours, or they have been thinned out, it begins to expand with vigour. ![]() Influence of situation.-As a rule young trees, when cultivated with others of a different species (to nurse them by their shelter in early life), are crowded together to promote straight long timber in the trunks for a tree that has not elbow room devotes all its energy to reaching the light above it, and the lower side boughs are weak and dwindle away. ![]()
