American Forest Trees Part 36

The serviceberry has a number of names: June berry, service-tree, May cherry, Indian cherry, wild Indian pear, currant tree, shadberry, savice, and sarvice. The northern limit of its range is in Newfoundland, the southern in Florida. It grows westward to Minnesota and Arkansas; but it is not plentiful except in certain restricted localities. It is most abundant among the ranges of the Appalachian mountains, and of its largest size toward the south. It is dispersed through forests generally, a tree or bush here and there; but it prefers the borders of forests, the brinks of cliffs, banks of streams, or some other open s.p.a.ce where light is abundant. It prospers most in rich soil but does fairly well in ground thin and dry.

The bloom, where it occurs, is a conspicuous feature of the landscape, though generally a tree on ten or twenty acres represents the density of its stand. The white, showy bloom comes early in spring, when most trees are yet bare of leaves. Occasionally, however, the serviceberry is more abundant, and the rows and clumps of blooming trees along creek banks or about the margins of glades or other openings in the forests, look like distant snowdrifts.

The fruit is a berry a half inch or less in diameter, bright red when fully grown in early summer, and changing to purple when ripe. The seeds are brown and very small, and each berry contains from five to ten. When circ.u.mstances are favorable, the tree is a prolific bearer, the slender branches bending beneath the weight. The tree need not reach any particular size before beginning to bear. On some of the severely burned summits of the Alleghany mountains in West Virginia, 4,000 feet or more above sea level, this tree, when only two or three feet high, bears abundantly. Such trees are probably sprouts from roots of older trunks destroyed by fire. At its best, it reaches a height of forty or fifty feet and a diameter of one or possibly two feet. Trunks of largest size occur among the southern Appalachian ranges.

The wood is heavy and very hard and strong. It is liable to check and warp in seasoning, is satiny, and is susceptible of a good polish.

Medullary rays are very numerous, but obscure; color, dark brown, often tinged with red. The wood is stronger, stiffer and heavier than white oak. It possesses most of the properties to make it a wood of great value, but its scarcity, and the usual small size of the trees, relegate it to the cla.s.s of minor woods. Some use is made of it in turnery and for other small articles. It is frequently planted in gardens for its bloom and berries. In such situations it lacks some of the charm which it holds as part and parcel of the wildwoods where its early spring bloom is thrown against a background of leafless branches.

WESTERN SERVICEBERRY (_Amelanchier alnifolia_) is also called pigeonberry and sarvice. Its botanical name refers to the resemblance of its leaves to those of alder. Its range covers a million square miles, and the species reaches its best development on islands and rich bottom lands of the lower Columbia river. It is found as far south as California, north to Yukon territory, east to Lake Superior and northern Michigan. It is nowhere a tree of attractive size, and is usually a shrub about ten feet tall and one inch thick. Trees are sometimes thirty feet high and six or eight inches in diameter. The fruit is blue-black and sweet, and pleasant to the taste if not overripe. Indians in the northern and western range of this tree gather the berries industriously while they last, and many of the white settlers do likewise. The birds flock to the thickets for their share, and though the berries are small, the bears in the region consider them worthy of prompt and continued attention. The berries are generally a little more than half an inch in diameter, and ripen in July or August, depending on lat.i.tude. Cattle, sheep, goats, and deer find this small tree or bush a source of food.

They do not object to eating the berries when obtainable, but their princ.i.p.al attack is on the leaves and tender shoots which afford excellent browse. Fortunately, the serviceberry is so tenacious of life that it is next to impossible to browse it to death. If eaten down to the ground, with little left but bare and barked trunks sticking up like bean poles, the roots will throw up sprouts year after year, making the service thicket a permanent browse-pasture. Fire is not able to destroy such a thicket, for, when the tops are burned off, the sprouts will quickly spring up with vigor unimpaired. As a source of food for insects, birds, beasts, and men, few trees, in proportion to size and quant.i.ty, are the equal of western serviceberry. Flowers, fruit, leaves and sprouts are all food for something.

LONGLEAF SERVICE TREE (_Amelanchier obovalis_) is by some regarded a variety rather than a species. It occupies in part the same range as serviceberry, but runs much farther north, reaching the valley of Mackenzie river in lat.i.tude 65. It is found in North Carolina and Alabama, but it is only a shrub in the extreme southern part of its range. The fruit ripens in early summer and is reddish purple. Trees are seldom more than thirty feet high and eight inches in diameter. A variety with large fruit is occasionally planted as an ornamental tree.

Unless the crop of serviceberries is unusually plentiful in a locality, the most of it is eaten by birds which temporarily abandon nearly all other sources of food and give their undivided attention to the perishable harvest which must be garnered in at once or it will be lost.

NARROWLEAF CRAB (_Malus angustifolia_) is one of the wild crabapples of the United States. They are of the genus _Malus_ and the thousands of varieties of cultivated apples are derived from them, or from other species found in the old world which are very similar. They belong to the rose family. The narrowleaf crab is found from Pennsylvania to Florida and westward to Tennessee and Louisiana. It thrives best in open s.p.a.ces in the forest and is often found in glades and along the banks of streams in the North, while in the South it occurs in depressions in the pine barrens. The flowers are much like those of apple, very fragrant, and in color are white, pink, or rose. When in full bloom, the tree is a beautiful object, and its odor is carried long distances. The fruit is an apple in all respects except size and taste. It is somewhat flattened, and is an inch or less across. It is fragrant when fully ripe, and many a person has been led by appearances to taste, only to meet disappointment. The flesh is hard and sour, and unfit for food in its natural state, but by cooking and artificial sweetening, it is made into preserves. The tree reaches a height of twenty or thirty feet and a diameter of eight or ten inches. It is smaller than the sweet crab. The wood is hard, heavy, light brown, tinged with red, with thick yellow sapwood. It is not put to many uses, but is occasionally made into small handles, and levers. It has been much used as stock on which to graft apples. Farmers who wanted orchards formerly dug up small crabapples in the surrounding woods and fields, planted them in an orchard, and when securely rooted, the apples of desired kinds were grafted on. If successful, the apple finally replaced the crab by spreading its own bark and wood over the entire trunk, until no part of the original stock remained visible. The sweet crab was also employed as a stock on which to graft apples.

SWEET CRAB (_Malus coronaria_) is the wild crab of the northeastern states, although it intrudes on the region to the southwest to a limited extent. It finds use in ornamental planting in the region of best growth. It is known as American crab, sweet scented crab, crab apple, wild crab, crab, American crab apple, and fragrant crab. Its range extends from the sh.o.r.es of Lake Erie in Canada, south through New York and Pennsylvania, along the Alleghany mountains to Alabama; west to Minnesota, eastern Nebraska, Kansas, Louisiana, and eastern Texas. It needs moist soil for good growth and the best types are found in the lower Ohio basin. In height this tree rarely exceeds thirty feet and it is bushy, having short rigid limbs. The leaves are rounded and sharply toothed, the blossoms generally white and very fragrant; the fruit small, dry, yellow, tinged with red. The wood is heavy, not strong, heart light red, sapwood yellow. It is used for tool handles, small turned articles, and for carving and engraving.

OREGON CRABAPPLE (_Malus rivularis_) grows wild from the Aleutian Islands, Alaska, southward to central California, and is of largest size in Washington and Oregon where trees are occasionally forty feet high and eighteen inches in diameter, but they are generally about ten feet high and form dense thickets. The fruit is oblong, ripens late in autumn, is greenish, or reddish, or clear lemon yellow in color, and rather pleasant to the taste. The tree grows slowly, the wood is hard, and light reddish-brown in color, and is suitable for tool handles.

IOWA CRAB (_Malus ioensis_) grows from Minnesota to Texas and is the common crabapple of the Mississippi basin. Large trees are twenty-five feet high and a foot in diameter. It is believed that this tree crosses with the common apple, and produces a variety known as the soulard apple (_Malus soulardi_). Wild apple (_Malus malus_) is a European species introduced into this country and now running wild.

MOUNTAIN ASH (_Pyrus americana_) is closely related to the crabs. It occurs from Newfoundland to Manitoba, and southward along the mountains to North Carolina. Trees have compound leaves, red berries the size of small cherries, and reach a height of thirty feet and a diameter of a foot or more. There are several forms or varieties, among them the small fruit mountain ash (_Pyrus americana microcarpa_) of the Alleghany mountains.

RED HAW

[Ill.u.s.tration: RED HAW]

RED HAW

(_Crataegus Coccinea_)

This tree belongs to the rose family, and the genus _Crataegus_ consists of a large group of small, th.o.r.n.y trees, scattered through many parts of the world. They are known by their thorns, but comparatively few of them are known by name to the ordinary observer, and they afford a perpetual source of study, victory, and bewilderment to the trained botanist. "No other group of American trees," says Sudworth, "presents such almost insurmountable difficulties in point of distinctive characters. It is impossible, and fortunately unnecessary, for the practical forester to know them all, and exceedingly difficult even for the specialist." More than one hundred species of these thorn trees occur in the United States, exclusive of shrubs. Their bloom resembles that of apple and pear trees. Bees and insects swarm round the flowering trees, a.s.sisting in cross fertilization. The various species are aggressive. They force their way into vacant s.p.a.ces, and their thorns protect them against browsing animals. The wood is sappy and heavy, and for most of the species it is valueless. The growing brambles, however, perform an important service in forest economy. Seeds of various valuable trees are blown by wind or carried by birds and mammals into the thickets where they germinate and get a start under the protecting shelter of the thorns. Finally the seedlings overtop the brambles, gain the mastery, shade the thorns to death, and develop valuable forests. The thorn trees shed their leaves annually. Their seeds are slow to germinate, some not sprouting until the second year. The fruit is worthless for human consumption, but some of it has a tart and not unpleasant taste. It is of many colors and sizes, depending on species.

No attempt is here made to name or to list the species. Such a list would, for most people, be a dull catalogue of names, and many of them in Latin because there are no English equivalents. A few representative species are given. The red haw, though not the most abundant, is widely distributed, and is probably as well known as any. Its range extends from Newfoundland westward through southern Canada to the eastern base of the Rocky Mountains, thence south to Texas and Florida. It covers one-half of the United States. In the northern part of its range the red haw is confined to the slopes of low hills and along water courses, but south in the Appalachian mountains it grows at an elevation of several thousand feet.

It has various names in different regions. It is called scarlet haw, red haw, white thorn, scarlet thorn, scarlet-fruited thorn, red thorn, thorn, thorn bush, thorn apple, and hedge thorn. The fact is worthy of note that it is well known and is clearly recognized in every region where it grows, though various names are given it.

The red haw never reaches large size. In rare cases it may attain a height of thirty feet and a diameter of ten inches, but it is usually less than half that size. Where it grows in the open it develops a round crown. The branches are armed with chestnut-brown thorns from an inch to an inch and a half in length. The bright scarlet color of the fruit gives name to the tree. It ripens late in September or in October, and at that time the tree presents a beautiful appearance. The branches frequently remain laden with fruit after the leaves have fallen.

The wood of red haw is of a high character and but for its scarcity would have wide commercial use. It is among the heavy woods of this country. A cubic foot of it, thoroughly seasoned, weighs 53.71 pounds.

The tree is of slow growth and therefore the annual rings are narrow, and the wood is dense. The evenness and uniformity of the rings of yearly growth make the wood susceptible of a high polish. The medullary rays are very obscure in red haw, and for that reason the appearance of the wood is much the same, irrespective of the direction in which it is cut. In that respect it is similar to the wood of most members of the thorn family--usually being too small to be quarter-sawed. However, even if the trees were large enough, quarter-sawing would bring out little figure.

Red haw is a lathe wood. It is well suited to some other purposes, and has been used for engraving blocks, small wedges, and rulers, but the best results come from the lathe. If it is thoroughly seasoned it is not liable to crack or check, though cut thin in such articles as goblets and napkin rings. The turner sometimes objects to the wood because of its hardness and the rapidity with which it dulls tools. This drawback, however, is compensated for by the smoothness and fine polish which may be given to the finished article. Red haw checker pieces have been compared with ebony for wearing quality. In color the ebony is more handsome, and on that account is generally preferred.

Perhaps the most extensive use of red haw is in the manufacture of canes. Most of the species of thorn are suitable for that purpose on account of their weight, strength, and hardness. Red haw is not specially preferred, but is used with others. As a source of wood supply, the tree will never be important, but as an adornment to the landscape it will always be valuable, and at the same time will fill a minor place in the country's list of commercial woods.

SUMMER HAW (_Crataegus aestivalis_) is a southern species which contributes more or less to the food supply of the people within its range. It is known also as May haw and apple haw. The flowers appear in February and March, are about one inch in diameter, and flushed with red toward the apex. The fruit ripens in May, is bright red, very fragrant, and is from half to three-fourths of an inch in diameter. The flesh is of a pleasant taste, and is gathered in large quant.i.ties by country people for making preserves and jelly. It is sold in town and city markets, particularly in New Orleans. The range of this thorn tree is from South Carolina and Florida, to Texas. It attains a height of twenty or thirty feet, and a diameter sometimes as great as eighteen inches. It reaches its largest size in Louisiana and Texas. It grows well on land which may be submerged several weeks in winter. The wood has not been reported for any use.

c.o.c.kSPUR (_Crataegus crus-galli_) may be taken as the type of more than twenty species of c.o.c.kspur thorns growing in this country. Its other names are red haw, Newcastle thorn, thorn apple, thorn bush, pin thorn, haw, and hawthorn. It grows southwestward from Canada to Texas, and extends into Florida. The largest trees are twenty-five feet high and a foot in diameter. The fruit is dull red, half inch in diameter, ripens in September and October, and hangs on the branches until late winter.

Hogs eat the fruit when they can get it, and boys utilize the small apples as bullets for elder pop guns. The thorns are formidable slender spines from three to eight inches long, strong, and extremely sharp.

They were formerly used as pins to close wool sacks in rural carding mills. The many species of c.o.c.kspur thorns are multiplied by numerous varieties. Fence posts and fuel are cut from the best trunks.

PEAR HAW (_Crataegus tomentosa_) is a representative of at least ten species. It is called pear haw without any very satisfactory reason, since the fruit bears little resemblance to pears. It is half an inch in diameter, dull orange red in color, and sweet to the taste, but it is of little value as food. The tree has been occasionally planted for ornament, but never for fruit. The flowers are showy. Trees at their best are fifteen or twenty feet high and five or six inches in diameter.

They have few thorns and such as they have are small. The tree's range extends from New York to Missouri, and along the Appalachian mountains to northern Georgia, and west to Texas and Arkansas. It is known in different parts of its range as black thorn, red haw, pear thorn, white thorn, common thorn, hawthorn, thorn apple, and thorn plum.

HOG HAW (_Crataegus brachyacantha_) is distinguished by its blue fruit.

The name indicates that the fruit is unfit for human food but is eaten by swine. In some parts of Louisiana the dense thickets produce considerable quant.i.ties of forage for hogs. The range is not extensive, being confined to Louisiana and eastern Texas where the tree occurs in low, wet prairies. The largest specimens are forty or fifty feet high and eighteen inches in diameter. It is one of the largest of the thorns, and the best trunks are of size to make small, very short sawlogs, but it does not appear that the wood has ever been manufactured into commodities of any kind. The tree is occasionally planted for ornament.

BLACK HAW (_Crataegus douglasii_) reaches its best development on the Pacific coast where trees occur thirty or more feet in height and a foot and a half in diameter. The princ.i.p.al range is west of the Rocky Mountains, from British Columbia to northern California, but it extends eastward to Wyoming, and the tree is found also in northern Michigan.

The fruit is black or very dark purple, is edible, and matures in early autumn, falling soon after. The heartwood is brownish-red. No use for the wood has been found on the Pacific coast.

WASHINGTON HAW (_Crataegus cordata_), also known as Washington thorn, Virginia thorn, heart-leaved thorn, and red haw, grows on banks of streams from the valley of the upper Potomac river southward through the Appalachian ranges to northern Georgia, and westward to Missouri and Arkansas. Flowers are rose-colored, the fruit ripens in the fall and hangs till late winter. Trees are twenty or thirty feet high, and a foot or less in diameter. Washington haw is frequently planted in this country and in Europe.

ENGLISH HAWTHORN (_Crataegus oxyacantha_) was introduced into this country from Europe and has become naturalized in some of the eastern states. Thirty or more varieties are distinguished in cultivation. It is worthy of note that, although the United States has more than 130 species of thorn trees of its own, with varieties so numerous that no one has yet named or counted all of them, a foreign thorn has been introduced and added to the number.

MAHOGANY

MAHOGANY

(_Swietenia Mahagoni_)

This tree belongs to the family _Meliaceae_ which has about forty genera, all of which are confined to the tropic except _Swietenia_ to which mahogany belongs. This tree has made its way up from southern lat.i.tudes and has secured a foothold in Florida where it is confined to the islands and the most southern part of the mainland.

No attempt is here made to settle or even to take part in the disputes among dendrologists as to what mahogany is. There are said to be more than forty different trees which pa.s.s as mahogany in lumber markets.

Various descriptions and keys have been published for the purpose of separating and identifying different woods which are bought and sold as mahogany. These woods grow on every continent except Europe; but those which pa.s.s as mahogany nearly all come from Africa or America. Some are well known, both as to origin and botany, while others are doubtful.

Logs sometimes appear in markets and no one knows where they come from, or the species which produce them. It has been maintained that annual rings will separate true mahogany from the false--that the true has no annual rings. At the best, this evidence is only negative and is worth little, since many tropical trees show no annual rings, and yet are no kin to mahogany. Neither is it certain that true mahogany shows no yearly rings. Some trees do not, but others may. The ring, as is well known, is produced because the tree grows part of the year and rests part. In the tropics where growth is continuous, the ring may not exist, but it sometimes does exist, and thus upsets the theory. Besides, it proves little in the case of mahogany which has a range extending from south of the equator northward into the temperate zone, where there are seasonal changes. It also grows near sea level and at considerable alt.i.tudes, and elevation alone might make considerable variation in the character of the wood.
