Part 33

It is a tree which will always be easily recognized after it has been seen and identified once. Its general outline, particularly when leaves are off, is different from other trees associated with it. It might possibly be mistaken for persimmon unless looked at closely; but there are easily-recognized points of difference. Its branches are very small, slender, and short. Its bark is rougher than that of any other gum, and is much darker in color. It is the bark’s color that gives the tree its name. The leaves have smooth edges. In the fall they change to gorgeous red, and one of their peculiarities is that half a leaf may be red while the other half remains green. Toward the end of the season, the green disappears. The dark blue drupes ripen in October. They do not seem to be food for any living creature.

Sawmills include black gum with tupelo in reporting lumber cut, and generally call both of them gum without distinction. The woods are quite different, and neither the standing tree nor the lumber of one need be mistaken for the other. The range of black gum is much more extensive than that of tupelo. Gum lumber cut north of the Ohio and Potomac rivers may be safely classed as black gum, though a little of both red and tupelo gum is found north of those streams. In the South, the species cannot be separated by regions, for all the gums grow from Texas to Virginia. The total annual output of black gum is not known, but some operators estimate it at about 20,000,000 feet a year, or nearly one-fourth as much as tupelo.

The bulk of black gum lumber is used in the rough, for floors, sheathing, frames, and scaffolds; but a considerable portion is further manufactured. The amounts thus used annually have been ascertained for a few states, and furnish a basis for estimates for the whole country: Mississippi, 7,000 feet; Maryland, 85,000; Illinois, 120,000; Louisiana, 120,000; Missouri, 190,000; Texas, 360,000; Massachusetts, 475,000; Alabama, 486,000.

The uses are general, except that the wood is not employed where attractive figure is required, for black gum is as plain as cottonwood. It is not displeasing in its plainness, for the surface finishes nicely with a soft gloss which, except that it lacks figure, suggests the sap of red gum. It is specially useful in situations where noncleavability is required. Black gum mallets for stone masons and woodworkers are in the market. Mine rollers require a much larger amount. The entire 85,000 feet reported in Maryland was made into such rollers. They furnish the bearing for the rope that hauls the car up the incline out of the coal pit. Its toughness qualifies it for wagon hubs, but it is sometimes objected to because its softness causes the mortises to wear larger where the spokes are inserted, and the wheel does not stand as well as when the hubs are of good oak. Early farmers and lumbermen preferred black gum for ox yokes, and some are still seen where oxen are used; but many other woods are as strong and equally as serviceable for yokes. Rollers of this wood for glass factories are common. It is made into hatters’ blocks where a wood is wanted which, when thoroughly seasoned, will hold its shape. It is less popular for this purpose than yellow poplar. One of the best places for black gum is in the manufacture of bored water pipe. The wood’s interlaced fiber prevents splitting under the internal stress due to hydrostatic pressure. The shell of such pipes can be thinner than with most woods. A drawback is found in the non-durable qualities of black gum. However, the internal pressure of water keeps the wood thoroughly saturated, and prolongs its life when used as pipes.

The makers of firearms employ black gum as gunstocks and pistol grips. The wood is stained to make it darker. It is cut by the rotary process into cheap veneer and is made into baskets and berry crates. Less trouble with the veneer, on account of breaking, is experienced than might be expected of a wood so cross-grained. It is sawed into thin lumber for boxes for shipping coffee and other groceries. It is a substitute for cottonwood and yellow poplar in the manufacture of certain lines of woodenware, notably, ironing boards, rolling pins, potato mashers, and chopping bowls. It is made into interior finish for houses; and furniture manufacturers find many places where it is a serviceable material. Musical instrument makers employ it, particularly as trusses for pianos, and in frames of pipe organs. In Louisiana it is converted into excelsior, and in Mississippi into broom handles, and parts of agricultural implements, particularly hoppers and seedboxes.

All gums are hard to season, and this one is no exception. It checks badly, but the checks are usually very small.

TUPELO

TUPELO

(Nyssa Aquatica)

Tupelo is said to be an Indian name. White men have applied it to three species of gum, all of the same genus, namely, black gum (Nyssa sylvatica), sour tupelo (Nyssa ogeche), and tupelo (Nyssa aquatica). Probably, the name tupelo applies as well to one as to the other, for it is said to refer to the drupe-like fruit; but custom confines the name to the species now under consideration. It is largest of the three species, most abundant, and most important. Sour gum is heard in Arkansas and Missouri, swamp tupelo in South Carolina and Louisiana, cotton gum in the two Carolinas and Florida, wild olive tree in Louisiana, and olive tree in Mississippi.

The range of tupelo extends from Virginia along the coast to Florida, northward in the Mississippi valley to southern Illinois, and westward to Arkansas and Texas. It prefers swamps and attains largest size in low ground which is subject to frequent overflow. The tree will stand in several feet of water the greater part of the year without injury. It is closely associated with cypress, the planer tree, and other species which grow in deep swamps.

Tupelo has not figured much in tree literature outside the books of botanists. Travelers and local writers have paid it little attention. It has not been remarkable for anything in the past, and has escaped observation to a large extent because it grows in swamps and along bayous, remote from the usual routes of travel. Its flowers attracted no attention, its fruit was worthless, and the early settlers did not put themselves to trouble to procure the wood for any purpose. That was the situation from the early settlement of the country where this species is found up to a very recent period when economic conditions began to bring tupelo into notice.

It first attracted attention in the markets as a substitute for yellow poplar. That was brought about by an attempt to pass it as poplar. The growing scarcity of that wood in the region about Chesapeake bay led to the trial of tupelo. It was sold as bay poplar, and the purchaser was left to infer that it was poplar cut in the region tributary to Chesapeake bay. Probably few buyers were deceived, but they found the wood a fair substitute for the yellow poplar which they had been purchasing in the Baltimore and Norfolk markets. It is known as bay poplar yet in many localities. It goes to England as such. One of its most important uses in that country is as casing for electric wire fittings. It has, however, many other important uses in England and on the continent. It is claimed that it may be stained to imitate Circassian walnut in the manufacture of furniture. This is possible, but most probably tupelo has been confused with red gum which is a well-known substitute for Circassian walnut.

Tupelo trees attain a height from seventy to a hundred feet, and a diameter of two to four feet above the swelled base. The general appearance of the bark suggests both yellow poplar and red gum. Trees have a habit of forking near the tops. The leaves are five or seven inches long, sometimes with smooth margins, and often with a few sharp points. Flowers appear in March and April, and fruit ripens early in Autumn. It is a dark purple, tough-skinned drupe, about an inch long.

The wood weighs 32.37 pounds per cubic foot. It is soft, and has about three-fourths the strength and little more than half the stiffness of white oak. It is not well suited to places where strength and rigidity are required. The fibers are interwoven, making the wood difficult to split. The heart is brown, often nearly white; the sapwood is very thick; and the annual rings are not clearly defined, because of the similarity between the springwood and summerwood. The pores are small but numerous, and are scattered evenly through the whole annual ring. The wood of roots differs from that of the trunk more than is usual with hardwoods. It is very light, and has been long employed in the South as a substitute for cork as floats for fish nets.

Tupelo is often logged with cypress. The two trees grow in close association in deep swamps. The butt cuts of tupelo are so heavy that they float deep, or even go to the bottom. It was formerly customary, and still is to some extent, to girdle trees whose trunks were to be floated to the mills. In the course of one season the standing trees dry sufficiently for the logs to float. At other times, trees are cut green, the logs are skidded and allowed to dry some months before they are rafted or floated to the mills. The sapwood is liable to decay, even in the brief period while the logs are on the skids. The wood may be protected against decay to some extent by smearing the ends of the logs with tar or some other substance which prevents the spores of decay-producing fungus from entering.

The seasoning of tupelo was formerly a problem exceedingly vexatious to the lumberman. The wood is full of water, and warping was one of the troubles which was constantly encountered. Finally experience gained the mastery, and seasoning troubles are fewer now. Shrinkage of four or five per cent is not unusual in passing lumber from the green to dry state.

Tupelo is like hickory in one respect--factories use more wood than the sawmills cut. The shops and manufacturing plants of ten states use as much tupelo as is cut by all the sawmills in the United States. These states are Alabama, Arkansas, Illinois, Louisiana, Maryland, Michigan, Mississippi, Missouri, North Carolina, and Texas. The reason for factory use exceeding the sawmill cut is that much reaches factories, in the form of veneer, which does not pass through a sawmill. The lumber output of most of the timber trees of this country is from one-third to one-half greater than the factory use. The difference represents the rough lumber used, and which never goes to a factory.

Tupelo lately entered the general market, but the yearly demand now exceeds 100,000,000 feet. Its uses range from boxes and cheap handles to interior finish and material for musical instruments. It is particularly liked for containers for berries and small fruits, on their way to market. Its whiteness and clean appearance fit it for that use.

Higher grades of shipping boxes are also made. Wholesale grocers order largely of this wood for spice, coffee, and tea boxes. These commodities are exacting in their requirements because their odor, which is often regarded as the criterion of their value, must not be impaired. A wood with an odor of its own is immediately ruled out. Cigar box makers use tupelo, sometimes as thin lumber for the whole box, but usually as backing over which to lay a thin veneer of Spanish cedar. Plug tobacco boxes are also made of tupelo.

In Illinois and Michigan tupelo is listed among woods manufactured into pianos, organs, mandolins, and guitars. In Maryland they make scows and barges of it. In Arkansas and Louisiana it is worked into excelsior and slack cooperage stock. It is a favorite wood in Mississippi for pumplogs and broom handles. Its leading reported use in Texas is for porch columns. In Missouri it is manufactured into laundry appliances, such as washboards, clothes racks, and ironing boards. In nearly all manufacturing centers of the country it is made into furniture and interior finish. It is frequently substituted for yellow poplar in panels, not only in furniture and cabinet work, but in carriage bodies.

The supply of tupelo in southern forests is fairly large, and will meet demand for some years, but it is a tree of slow growth, and when present stands are cut, a new supply will probably never come.

SOUR TUPELO (Nyssa ogeche) appears to be the only member of the gum group whose fruit is of any value to man, and it is not very important. The large, dull red drupes ripen in July and August, and sometimes hang on the trees until late fall, allowing ample time for gathering them. They are very sour, for which reason the tree is called sour gum. The fruit is put through a pickling process which renders it palatable and it is not an infrequent article on southern pantry shelves. The range of the tree is confined to the region near the coast from the southern border of South Carolina, through the Ogeechee river valley in Georgia, to northern and western Florida. The botanical name refers to the river along whose course the trees are most abundant. Local names are gopher plum, Ogeechee lime, and wild lime. The tree is sixty or seventy feet high, one or two in diameter, and is often divided in several stems. Its wood is lightest of the gums, weighing only 28.75 pounds per cubic foot. It is diffuse-porous, and the springwood is scarcely distinguishable from the summerwood. The annual rings of growth are indistinct, and the medullary rays are thin and inconspicuous. The wood is weak, soft, tough, and white, and little difference is apparent between heart and sapwood. The flowers are rich in honey and are valuable to bee keepers. It appears that no reports exist of the use of this wood for any purpose. It is not abundant anywhere.

WATER GUM (Nyssa biflora) is a member of the gum group, and is of small importance. Trees above thirty feet high are unusual, and the trunk is of poor form, owing to its greatly enlarged base. This gum is found on the margins of small ponds in the pine barrens from North Carolina to the Gulf coast. The leaves turn purple and red in the fall, and are then conspicuous objects. The fruit is a blue drupe about a third of an inch long. The wood is light, tough, and difficult to split.

BLACK WALNUT

BLACK WALNUT

(Juglans Nigra)

This tree has few names. It is called walnut, black walnut, and walnut-tree. The color of the wood and bark is responsible for the word black in the name, though some people use the adjective to distinguish the tree from butternut which is often known as white walnut. The natural range of black walnut covers 600,000 or 700,000 square miles, and it has been extended by planting. Its northern limit stretches from New York to Minnesota, its southern from Florida to Texas. It is difficult to say where the species found its highest development in the primeval forests, for very large trees were reported in New York, among the southern Appalachian mountains, in the Ohio valley, and beyond the Mississippi in Arkansas, Oklahoma, Missouri, and Kansas. The wood cut in Ohio and Indiana has been of greater commercial importance than that from any other portion of its range, but that has been due, in part, to the fact that it came into market before the best of the forest growth had been destroyed in those states, and instead of burning it or mauling it into rails, as eastern farmers did in early times, the farmers of the Ohio valley sold their walnut. Early in the history of black walnut lumbering, Indiana and Ohio came to the front as the most important sources of supply, and they still hold that position, notwithstanding the original forests of those states were supposed to be nearly exhausted long ago. The states cutting most black walnut in 1910, in the order named, were Ohio, Indiana, Illinois, Kentucky, Tennessee, Missouri, West Virginia, Virginia, Pennsylvania, and Iowa.
