Leaves, Flowers, and Fruit of P. avium.
The Whitebeam may be raised from seed, which should be sown as soon as the fruit is ripe; otherwise, if kept till spring, and then sown, they will not come up till the spring following. The varieties may be propagated by cuttings, or by layering; but they root, by both modes, with great difficulty. Layers require to be made of the young wood, and to remain attached to the stool for two years. The rate of growth, when the tree is young, and in a good soil, is from eighteen to twenty-four inches a year: after it has attained the height of fifteen or twenty feet it grows much slower; but it is a tree of great duration. The roots descend very deep, and spread very wide; and the head of the tree is less affected by prevailing winds than almost any other. In the most exposed situations, on the Highland mountains, this tree is seldom seen above ten or fifteen feet high; but it is always stiff and erect. It bears lopping, and permits the grass to grow under it.
The wood is hard and tough, and of a very close grain, and will take a very high polish. It is much used for knife handles, wooden spoons, axle-trees, walking-sticks, and tool-handles. Its principal use, however, is for cogs for wheels in machinery.
