And though she boasts no charm divine,
Yet she can carve, and make Birch wine.
Pomona's bard says, also, that
—Even afflictive Birch,
Cursed by unlettered idle youth, distils
A limpid current from her wounded bark,
Profuse of nursing sap.
We are informed that a Birch-tree has been known to yield, in the course of the season, a quantity of sap equal to its own weight. It is obtained by inserting, in the early part of spring, a fosset made of an elder stick, with the pith taken out; and setting vessels, or hanging bladders, to receive the liquor. The sooner it is boiled the better; so that, in order to procure a sufficient quantity in a short time, a number of trees should be bored on the same day, and two or three fossets inserted in each of the larger trees. Sugar is now commonly used to sweeten it, in the proportion of from two to four pounds to each gallon of liquor. This is allowed to simmer so long as any scum rises, which must be cleared as fast as it appears. It is then poured into a tub to cool, after which it is turned into a cask, and bunged up when it has done working; and is ready to be drunk when a year old.
As before remarked, the timber of the Birch is of little value; though in the Highlands, where pine is not to be had, it is used for all purposes. Its stems form the rafters of cabins; "wattles of the boughs are the walls and the door; and even the chests and boxes are of this rude basket-work."
Light and strong canoes were formerly made of this timber in Britain, and also in other parts of Europe; and are even now in the northern parts of America. It also makes good fuel; and in Lancashire great quantities of besoms are made for exportation from the slender twigs. The bark is used in Russia and Poland for the covering of houses, instead of slates or tiles; and anciently the inner white cuticle and silken bark were used for writing-paper. Coleridge describes
A curious picture, with a master's haste
Sketched on a strip of pinky-silver skin
Peeled from the Birchen bark.
There is no part of this tree, however, that is not useful for some purpose or other. Even its leaves are used by the Finland women, in forming a soft elastic couch for the cradle of infancy.
Gilpin particularly notes a beautiful variety of the White Birch, B. pendula, sometimes called the Lady Birch, or the Weeping Birch. Its spray being slenderer and longer than the common sort, forms an elegant pensile foliage, like the weeping willow, and, like it, is put in motion by the smallest breeze. When agitated, it is well adapted to characterize a storm, or to perform any office in landscape which is expected from the weeping willow. This is agreeably described in Wilson's Isle of Palms:
