How the wind roars in the Pine branches on the high mountain lands! It is like the sound of the sea. If the Pine tree had broad leaves, such as the Sycamore or the Lime tree, it would soon be blown down; but the storm gusts pass through its fine needle-leaves, and no harm is done.

The trunk of the Scotch Pine is very rough, and it is covered with rugged pieces of reddish bark, separated from each other by deep furrows. It rises to a great height, throwing out many large branches on each side, and there is always a bushy rounded tree-top looking up to the sky. In a Pine forest the lower part of the tree is usually bare. This is because the trees are planted so close together there is little air except near the top of the tree, and the lower branches are stifled.

Beneath the branches the ground is always carpeted with fallen Pine leaves, and very curious these Pine leaves (2) are. They look like green needles with soft blunt points, and the edges of each needle are rolled back so that the leaf appears round above and is boat-shaped below. The under-side of the needle is much lighter in colour than the dark green surface.

These needle-leaves usually grow in pairs, though you may find a bunch containing three or even four needles; they are held together by a thin grey sheath, which looks like paper and clasps the end of the bunch. These needle-bunches are placed all round the twig, close together, so as to form a dense brush. They remain on the tree for two or three years, then they fall; but their work is not done. Very often the Pine tree seed has been carried to some sandy sea-shore upon which nothing is willing to grow. There it takes root and flourishes, and in course of time it throws down handfuls of withered needle-leaves on the loose sandy ground. These needles decay and form a bed of soil which binds the sand together, and when the wind and the birds bring other seeds, they find a place in which they can take root and grow. In France great tracts of waste land have become valuable in this way through the planting of Pine trees.

The Pine tree has its flowers in catkins and its fruit in cones. The catkins are of two kinds, and they grow on the same tree, sometimes on the same branch. The stamen flowers (3) are found in dense spikes at the end of last year’s bushy twig. They look like a cluster of bunches of small yellow grains from which a tuft of fine green spears rises in the centre. These grains are the stamen heads, and in May and June they send out clouds of fine yellow powder, which floats in the air and settles on the leaves and on the grass and on the margins of lakes and rivers, where you can see little patches of it lying. Country peasants sometimes tell you that this yellow powder is sulphur which has fallen from the sky during a thunder-storm!
