The wood of the birch is of very extensive use, as we have before stated under the article. Prof. informs us, that the Tartars cover their huts with its bark, and the navigators of the Volga construct of it portable boats, cradles, &c.; it is also used in fumigations, to purify a vitiated atmosphere. The Laplanders cut the outer bark into thongs, of which they manufacture ropes, baskets, and other utensils; and it even forms some part of their wearing apparel: it is also used in dyeing; and, as a substitute for oak-bark, in tanning. The Swedish house-wives employ this bark, after burning it to a certain degree, as a cement for broken china, or earthen-ware. When boiled with alum, it affords a dye of a dark-red colour. asserts, that the bark is better for tanning, when dried, than in a fresh state. For this purpose, it is cut into small pieces, and boiled for half an hour in pure water; and the prepared hides are steeped in it, while luke-warm. The ley is again boiled on the two following days, and the steeping of the leather as often repeated; after which it is suspended to dry in the air. Leather thus prepared, is said to be water-proof.

The leaves of the birch give a yellowish colour to wool, which has been previously prepared with alum. Those collected in the spring, however, are not so proper for dyeing, as the autumnal leaves; because the former produce a greenish tinge; but the latter afford a beautiful yellow colour. They have also been used in the dropsy, itch, &c. either applied externally, or in decoctions taken by the mouth.

The fungus which grows on the trunk of the birch-tree, is a very good styptic; and when boiled in water, beaten, and dried in an oven, it makes excellent touch-wood.

Birch-twigs are used for fishing rods and brooms; as well as by bird-catchers, who smear them with bird-lime.

Birch-Wine was formerly in considerable repute, as a remedy for nephritic disorders, but is disused in modern practice. As it is a rich cordial, and, according to Dr., an excellent remedy for consumption, and the scurvy, we shall acquaint our readers with the method of preparing it; though we have no experience of its medicinal powers.

The juice or sap of the birch-tree, should be extracted about the beginning of March, when the buds begin to swell, and before they have opened their leaves. An incision, or hole must be made in the trunk, almost as deep as the pith, under some branch of a well-spreading tree, on its south-western side, and about one foot above the ground: a hollow tube should then be fitted to the aperture, through which the sap will flow similar to distillation. On applying a little mould to the orifice, the wound will heal, and the bark afterwards close. Some persons are of opinion, that the sap drawn from the trunk of the tree, is not so pure as that obtained from its higher branches. To prevent this juce
