The Larch (1) was brought to Britain in the seventeenth century from its home on the high mountains of Germany, Austria, and Italy. Ithas taken kindly to our cheerless climate, and now covers acres of what was once barren moorland.
A few years after Larches are planted the long flexible branches of the young trees meet and form a thicket into which little light or air can enter, and the weeds and heather growing round the tree roots are stifled. Each winter the Larch sheds on the bare ground millions of its tiny needle-leaves, which enrich the soil.
After the young trees have grown to a certain height the forester thins the plantation; he cuts down a number of the young trees, so that those which remain may have more room to grow, and he removes all the withered branches near the ground. This allows the sunshine to reach the soil, and soon after a crop of soft, fine grass is seen carpeting the ground. Sheep and cattle can now be pastured where a short time before there grew nothing but heather and weeds.
Look at a Larch plantation in winter time, and you will think that all the trees are dead. The Pines and the Firs are resting, and the Oaks and Beeches seem asleep, but their branches do not have the dead, withered look of the Larch trees. Come again early in spring, and you will see a wonderful change. These dead twigs are now a pale glossy brown, so glossy that they might have been varnished. Try to pull one, and you will find how tough and sound it is; only where the twig joins the branch can you separateit from the tree; and what a delightful smell of turpentine remains on your fingers after gathering the Larch twigs!
In the trunk of this tree there are stores of turpentine, tiny lakes of it, which are of considerable value. In Italy, where the Larch trees grow to great size, small holes are bored through the trunk to the very heart of the tree, and a thin pipe is put in. Then a can is hung on the end of the pipe, and the pure turpentine juice drops steadily into the can. It is then strained, and is sold just as it comes from the tree.
Early in April the Larch tree begins to get ready for summer; it is always one of the first trees to awaken at the call of spring. On each flexible twig there appear little brown scaly knobs like small beads, placed either singly or in pairs with a short space between each bead. In a few days these scaly beads burst open, and a tuft of vivid green leaves (2), like the fringes round the mouth of a sea-anemone, peeps out. These leaves are soft and flat and slender, very different from the hard needles of the Pine and the harsh swords of the Fir trees, and they grow in tufts, thirty or forty together, rising from the centre of the scaly brown bead. Each tuft is of the brightest green. So the Larch tree is a very vision of spring in the dark Fir plantations, while the leaf buds of many other trees are only awakening from their winter sleep.
In the hedgerows the Hawthorns are in full leaf, the stamen flowers cluster on the boughs of the Elm, and the Hazel and Willow catkins dangle their tails in the wind; but the forest trees remain sombre and gloomy, and the young Larch seems gay as the sunlight among them. As the season advances the Larch tree leaves become darker, and they fall early in winter. We have only one other cone-bearing tree which is not evergreen, and that is the Cypress.
After the leafy tufts appear you will notice that some of the scaly brown beads have not produced any leaves; instead they have become tiny oval catkins (3), which are made up of a crowd of small yellow grains. These catkins are the stamen flowers, and in the yellow grains, which are the heads of the stamens, is prepared the dust powder which the seed flowers require to assist them in getting ready the new seed.
On the same twig, and not far from the stamen catkins, you see a beautiful deep rose-red seed catkin (4). This tiny rose-red catkin is very lovely among the brilliant green tufts of leaves; no other cone-bearing tree has anything so attractive to show us. At first the catkin scales are soft and fleshy; they overlap each other very loosely, and from the base of each scale there rises a bright green point like a single needle-leaf.
In a few weeks the catkin has become a young cone (5), which looks like a small rosy egg sittingerect on a bent footstalk, then the rose-pink colour fades from the cone, and the scales become hard and woody. Behind each scale lie two tiny white seeds with wings, and there is a coating of sticky resin over these seeds to keep them dry. The ripe cones (6) remain on the tree for years, long after the seeds have been blown away on their transparent wings by the wind.
The crossbill often builds his nest in a Larch tree. He is particularly fond of Larch tree seeds, and is very clever at picking them out of the ripe cones.
The trunk of a full-grown Larch is reddish brown in colour, and it is covered with a rough, scaly bark, which is often hung with hoary tufts of pale grey lichen.
Larch wood is very valuable, and is used for many purposes. It is very tough, and does not rot in water. Joiners tell us there are fewer knots in planks of Larch than in those of either Silver Fir or Spruce. Wood knots are scars which occur where a dead branch has fallen from the tree, and builders complain that when the tree is sawn into planks, the knots shrink and fall out, leaving a round hole. This reduces the value of the wood; but in the Larch planks the knots are said not to come away from the surrounding wood.
