CHESTNUT, CHINQUAPIN. (Castanea.)

The chestnut is found in the temperature regions of central and southern Europe, northern Africa, China, Japan, and eastern North America. The wood is valued in construction, and the much-prized nuts are regarded as a food rather than a confection. European chestnut wood was once high in favor, although examination of structures in which it was supposed to have been used indicates that in some instances oak had been mistaken for it and had been employed in its place.

The North American chestnut affords a weak, brittle, but easily worked and very durable wood, such as is admirably adapted for beams, ties, and sills, where lightness and durability rather than much transverse strength are required. Trees in Europe have attained to great size and age. Micheaux mentions one thirty feet in circumference six feet from the ground and said to have been standing for a thousand years. The famous Mt. Etna chestnut[37] is reported to have measured two hundred and four feet in circumference. Large trunks are apt to be hollow, affording brittle, useless wood. The botanical relation between the American and European chestnuts is not distinct. Some consider the former a distinct species, others a variety only. The name "Chinquapin" applies to two distinct botanical species, one, the Castanea pumila, closely related to the common chestnut; the other, Castanopsis chrysophylla, belonging to the same family (Cupuliferæ), but to quite another genus. Both afford woods resembling, but heavier than, chestnut.

PLATE 11. CHESTNUT (Castanea dentata).

Top-Left--(Courtesy N. C. Geological Survey.)

The chestnut may be known by its large prickly burr, [p057] containing from one to three thin-shelled, triangular, wedge-shaped nuts. Both chinquapins have prickly burrs containing one, or sometimes two, sweet edible nuts. Three of the four known species of the genus Castanea grow in North America, one the common chestnut (Castanea vulgaris); another the Chinquapin (Castanea pumila); the third a plant never attaining to the size of a tree. The Chinquapin (Castanopsis chrysophylla) is the only North American representative of a genus including twenty-five species. Keeler says that Castanea is from a town of that name in Thessaly, or from another town of that name in Pontus. [p058]

BEECH.(Fagus.) IRONWOOD.(Carpinus, Ostrya, etc.)

Beech is well known on the eastern continent. The common beech (Fagus atropunicea) is the only American representative. Eastern species have figured in literature since the time of Virgil. The northern nations early wrote upon thin tablets of beechwood, and boc, bok, and buche, the northern names for beech, finally gave origin to the word book.[38] American Indians believed that the beech was proof against lightning.

Beech (Fagus atropunicea).

Beechwood is hard, heavy, strong, not durable when exposed, and somewhat subject to attack by insects. European engineers employ it to a considerable extent in construction, but it is seldom used in America save for indoor finish, furniture, handles, flooring, and the like. The small edible nuts, known as beech-mast, are pressed abroad for a fixed oil, resembling and used in place of that from the olive. They are seldom gathered in this country, but are devoured by animals. Beech-trees have smooth, light-colored bark, and are very attractive in their winter appearance. They may be recognized earlier in the season by their small prickly burrs, each containing two triangular, sharp-edged nuts. There are fifteen or more species known to belong to this genus. Fagus is from phago, to eat, and refers to the nut.

PLATE 12. BEECH (Fagus).

The name Ironwood has been applied to Blue Beech (Carpinus caroliniana), to the Hornbeam (Ostrya virginiana), and to at least eight other North American species affording unusually hard and heavy woods, such as are used for handles [p061] and implements.[39] Trunks of trees affording these woods are generally small and the weight of the woods is so great as to prevent their use in construction. [p062]

PLATE 13. SYCAMORE (Platanus occidentalis).

Quartered Sycamore Wood.

SYCAMORE. (Platanus.)

The name Sycamore applies to a maple (Acer pseudo-platanus) in Europe, to a fig-tree (Ficus sycomorus) in the Orient,[40] and to the buttonball or plane tree (Platanus) in North America. Of the plane trees (Platanus) the common or Oriental plane (Platanus orientalis) is a native of Europe; the plane, buttonball, or sycamore tree (Platanus occidentalis) is a native and common tree in eastern North America; and the California plane, buttonball, or sycamore (Platanus racemosa) is a native of western North America.

Sycamore (Platanus occidentalis).

The sycamore stands for curiosity, because of its Biblical association with Zaccheus. Many European sycamores were planted by religious persons during the middle ages because of the belief that they were the trees thus referred to in the Bible.

The woods afforded by the American sycamores have unusually complicated, cross-grained, but beautiful structures, difficult to work, but standing well and valued for cabinet work and small articles. American trees are often very large.

American buttonball or sycamore trees are distinguished by rough balls which remain hanging on long stems throughout the winter. The bark also is shed to an unusual extent; flakes of the outer cover drop away, exposing smooth inner surfaces so white as to appear as if painted. Six or seven species are included in the genus; three occur in North America. Platanus is from platus, signifying broad, and refers to the shape of the leaves. [p066]

BIRCH. (Betula.)

The birches grow in Europe, Asia, and North America, their ranges on the latter continent extending far into the north.[42] Their history is remote and probably began with attention to the bark rather than to the wood.

Birch-bark is smooth, pliable, water-tight, and by reason of its resinous oils so durable that it often remains intact long after the wood inside of fallen trees has disappeared. It is separable into thin layers and was early employed as a writing material.[43] Houses have been covered by it and it has been used for cordage, utensils, "damp courses," and even rude clothing. The American Indians employed it for canoes, tents, troughs, and buckets. The wood is hard, heavy, strong, fine-grained, and beautiful. It shrinks in seasoning, works easily, stands well when not exposed. It is used for spools, woodenware, and other small articles, as well as for interior finish and cabinet work. Figured birch is one of the most beautiful of American cabinet woods.[44] Birch is often stained so as to imitate cherry and mahogany; the best imitations of the latter wood are of birch. Birch is commercially divided, according to the quantity of heartwood present, into white birch and red birch. The wood is "white" when the amount is small, and as heartwood increases with age the same tree might at one time afford white and at another red wood.

Birch trees may be known by their more or less laminated bark with its peculiar long horizontal lenticles or dashes. The [p069] leaves of the several birches differ but little, but the decided colors exhibited by their barks give names and serve to distinguish the species. Nine of the twenty-four known species of birch occur in North America; six are trees and the others low shrubs. Betula is said to be derived from bitumen. [p070]

FOOTNOTE

[42] Birch forms large forests in the North.

[43] Pliny and Plutarch agree that the famous books of Numa Pompilius, written 700 years before Christ, were upon birch-bark. (Keeler.)

[44] The banquet-hall of the famous Auditorium Hotel in Chicago is finished in birch. (Kidder.)
