The various See also:species of,See also:birch are mostly trees of See also:medium See also:size, but several of them are merely shrubs
.
They are as a See also:rule of a very See also:hardy See also:character, thriving best in See also:northern latitudes—the trees having See also:round, slender branches, and serrate, See also:deciduous leaves, with barren and fertile catkins on the same See also:- TREE (0.

The See also:common white or See also:silver birch (B. See also:alba) (see fig.) grows throughout the greater See also:part of See also:Europe, and also in See also:Asia See also:Minor, See also:Siberia and See also:North See also:America, reaching in the north to the extreme limits of See also:forest vege-
tation, and stretching southward on the See also:European See also:continent as a forest tree to 450 N. See also:lat., beyond which birches occur only in See also:special situations or as isolated trees
.
It is well known in See also:England for its graceful See also:habit, the slender, See also:grey—or white—barked See also:stem, the delicate, drooping branches and the quivering leaves, a See also:bright, clear See also:green in s p r i n g, becoming duller in the summer, but often keeping their greenness rather See also:late into the autumn
.
The male and See also:female See also:flowers are See also:borne on See also:separate catkins in See also:April and May
.
It is a See also:short-lived tree, generally from 40 to 50 ft
.
high with a See also:trunk seldom more than 1 ft. in See also:diameter
.
It flourishes in See also:light soils and is one of the few trees that will grow amongst heather; owing to the large number of " winged seeds " which are readily scattered by the See also:wind, it spreads rapidly, springing up where the See also:soil is dry and covering clearings or See also:waste places
.
The birch is one of the most wide-spread and generally useful of forest trees of See also:Russia, occurring in that See also:empire in vast forests, in many instances alone, and in other cases mingled with pines, poplars and other forest trees
.
The See also:wood is highly valued by See also:carriage-builders, upholsterers and turners, on See also:account of its toughness and tenacity, and in Russia it is prized as firewood and a source of See also:charcoal
.
A very extensive domestic See also:industry in Russia consists in the manufacture of wooden spoons, which are made to the extent of 30,000,000 annually, mostly of birch
.
Its pliant and flexible branches are made into brooms; and in See also:ancient See also:Rome the See also:fasces of the Iictors, with which they cleared the way for the magistrates, were made up of birch rods
.
A similar use of birch rods has continued among pedagogues to times so See also:recent that the birch is yet, literally or metaphorically, the See also:instrument of school-See also:room discipline
.
The bark of the common birch is much more durable, and industrially of greater

value, than the wood
.
It is impermeable to See also:water, and is there-fore used in northern countries for roofing, for domestic utensils, for boxes and jars to contain both solid and liquid substances, and for a See also:kind of bark shoes, of which it is estimated 25 millions of pairs are annually worn by the See also:Russian peasantry
.
The jars and boxes of birch bark made by Russian peasants are often stamped with very effective patterns
.
By dry See also:distillation the bark yields an empyreumatic oil, called diogott in Russia, used in the preparation of Russia See also:leather; to this oil the See also:peculiar pleasant odour of the leather is due
.
The bark itself is used in tanning; and by the Samoiedes and Kamchatkans it is ground up and eaten on account of the starchy See also:matter it contains
.
A sugary See also:sap is See also:drawn from the trunk in the See also:spring before the opening of the See also:leaf-buds, and is fermented into a kind of See also:beer and See also:vinegar
.
The whole tree, but especially the bark and leaves, has a very pleasant resinous odour, and from the See also:young leaves and buds an essential oil is distilled with water
.
The leaves are used as See also:fodder in northern latitudes
.
The species which belong peculiarly to America (B. lenta, excelsa, See also:nigra, papyracea, &c.) are generally similar in See also:appearance and properties to B. alba, and have the same range of applications
.
The largest and most valuable is the See also:black birch (B. lenta) found abundantly over an extensive See also:area in See also:British North America, growing 6o to 70 ft. high and 2 to 3 ft. in diameter
.
It is a wood most extensively used for See also:furniture and for carriage-See also:building, being tough in texture and bearing shocks well, while much of it has a handsome See also:grain and it is susceptible of a fine See also:polish

The See also:canoe or See also:paper birch (B. papyracea) is found as far north as 70° N. on the See also:American continent, but it becomes rare and stunted in the See also:Arctic circle
.
See also:Professor See also:Charles Sprague See also:Sargent says: " It is one of the most widely distributed trees of North America
.
From Labrador it ranges to the See also:southern shores of See also:Hudson's See also:Bay and to those of the See also:Great See also:Bear See also:Lake, and to the valley of the See also:Yukon and the See also:coast of See also:Alaska, forming with the See also:aspen, the See also:larch, the See also:balsam See also:poplar, the banksian See also:pine, the black and white spruces and the balsam See also:fir, the great subarctic transcontinental forest; and southward it ranges through all the forest region of the Dominion of See also:Canada and the northern states." It is a tree of the greatest value to the inhabitants of the See also:Mackenzie See also:river See also:district in British North America
.
Its bark is used for the construction of canoes, and for drinking-cups, dishes and baskets
.
From the wood, platters, See also:axe-handles, See also:snow-See also:shoe frames, and See also:dog sledges are made, and it is worked into articles of furniture which are susceptible of a See also:good polish
.
The sap which flows in the spring is drawn off and boiled down to an agreeable spirit, or fermented with a birch-See also:wine of consider-able alcoholic strength
.
The bark is also used as a substitute for paper
.
A species (B

.
It is also said to be used as See also:writing paper by the mountaineers; and in See also:Kashmir it is in See also:general use for roofing houses
