Part 26 (1/2)

Red gum reproduces both by seed and by sprouts, fairly abundantly every year, but about once in three years there is a heavy production. In the Mississippi valley the abandoned fields on which young stands of red gum have sprung up are, for the most part, being rapidly cleared again. The second growth here is considered of little worth in comparison with the value of the land for agricultural purposes.

A large amount of red gum growing in the South can be economically transported from the forests to the mills only by means of the streams, owing to the expense of putting in railroads solely for handling the timber. Green red gum, however, is so heavy that it scarcely floats and, to overcome this difficulty, various methods of driving out the sap before the logs are thrown into the river have been tried. One method is to girdle the trees and leave them standing a year. That partly seasons them, but does not give time for the sapwood to decay. The logs from such trees float readily, and the swamps and streams are utilized to carry the logs to the mills.

Some years ago that method of seasoning red gum was extensively advertised in England by contractors who sold paving blocks of this wood. It was claimed that the common defects of red gum were thus overcome. Large sales of paving material were made, particularly in London, and red gum was popular for a time, but it finally lost its hold as a paving wood in compet.i.tion with certain Australian woods. The theory that by girdling a tree and allowing it to die, the amount of heartwood will be increased has been abandoned. In selecting trees for cutting, those with doty tops, rotten stumps, and heavy bark, indications of an old tree which contains a very small proportion of sapwood, are now chosen. These are found mainly in the drier localities.

In low, wet places the trees have more sapwood and are smaller. The heartwood forms while the tree is living, not after it dies.

The rapidity with which red gum has come into use in this country and elsewhere is the best evidence of the wood's real value. Its range of uses extends from the most common articles, such as boxes and crates, to those of highest cla.s.s, like furniture and interior finish. It is only moderately strong and stiff, and is not a compet.i.tor of hickory, ash, maple, and oak in vehicle manufacturing and other lines where strength or elasticity is demanded; but in nearly all other cla.s.ses of wood uses, red gum has made itself a place. It has pushed to the front in spite of prejudice. As soon as the difficulties of seasoning were mastered, its victory was won. Its annual use in Michigan, the home and center of hardwood supply, exceeds 20,000,000 feet in manufactured articles, exclusive of what is employed in rough form. In Illinois, the most extensive wood-manufacturing state in the Union, red gum stands second in amount among the hardwoods, the only one above it being white oak. In Kentucky, only white oak and hickory are more important among the factory woods, while in Arkansas, where the annual amount of this wood in factories exceeds 100,000,000 feet, it heads the list of hardwoods.

As a veneer material, it is demanded in four times the quant.i.ty of any other species. The veneer is nearly all rotary cut, and it goes into cheap and expensive commodities, from berry crates to pianos.

The wood weighs 36.83 pounds per cubic foot. It is straight-grained, the medullary rays are numerous but not prominent, the pores diffuse but small, and the summerwood forms only a narrow band, like a line. The annual rings do not produce much figure, but wood has another kind of figure, the kind that characterizes English and Circa.s.sian walnuts, smoky, cloudy, shaded series of rings, independent of the growth rings.

They have no definite width or constant color, but the color is usually deeper than the body of the wood. This figure is one of the most prized properties of red gum. It is that which makes the wood the closest known imitator of Circa.s.sian walnut.

All red gum is not figured, and that which is figured may be worked in a way to conceal or make little use of the figure. It shows best in rotary cut veneer and tangentially sawed lumber. Various woods are imitated with red gum. It is stained or painted to look like oak, cherry, mahogany, and even maple.

Some trees have thin sapwood, and others are all sapwood. This peculiarity sometimes leads to misunderstandings in lumber transactions.

A buyer specifies red gum, expecting to get red heartwood, but the seller delivers lumber cut from the red gum tree, though light colored sapwood may predominate. Properly speaking, the name is applied to the tree as a whole and does not refer to any particular color of wood in the tree. The term ”red” is said to have referred originally to the color of autumn leaves, and not to the wood.

The fruit of red gum is a bur, midway in appearance and size between the sycamore ball and the chestnut bur. It hangs on the tree until late in winter. The resin which exudes from wounds in the bark is of much commercial importance and is s.h.i.+pped from New Orleans and Mexican ports.

Near the northern limit of the species' range the trees yield little resin, but it is abundant farther south. In the southern states it is used locally as chewing gum. It is known commercially as copalm balm.

WITCH HAZEL (_Hamamelis virginiana_) is a cousin to red gum, but there is small resemblance. It is known as winter bloom, snapping hazel, and spotted alder. Its range extends from Nova Scotia to Nebraska, Texas, and Florida. It reaches its largest size among the southern Appalachian mountains where the extreme height is sometimes forty feet, with a diameter of eighteen inches; but few people have ever seen a witch hazel that large. It is usually fifteen or twenty feet high and three or four inches in diameter. The wood is much like that of red gum, being diffuse-porous with obscure medullary rays, and a thin line of summerwood. It is of little commercial use; in fact, no report has been found that a single foot of it has ever been used for any purpose. Yet it is a most interesting little tree.

It blooms in the fall, sometimes as late as the middle of November.

Its rusty summer foliage turns yellow in autumn, and as the leaves begin to fall, the tree bursts into delicately-scented golden flowers, the most visible part of each consisting of four petals which float out like streamers. At the same time that flowers are scenting the air, the seeds are discharging. A full year is required to ripen them; and when dry, cold weather comes, the contraction of their envelopes shoots them with sufficient force to send them fifteen or twenty feet. They depend on neither wings, birds, nor squirrels to scatter them. The origin of the name witch hazel is disputed; but the person who examines the open-topped b.u.t.ton which holds the black seeds, and notes the fantastic resemblance to a weasen face, will feel satisfied that he can guess the origin of the name. The tree's bark is used for medicine, in extracts and gargles.

BLACK GUM

(_Nyssa Sylvatica_)

Black gum grows from the Kennebec river in Maine to Tampa bay, Florida; westward to southern Ontario and southern Michigan; Southward through Missouri, as far as the Brazos river in Texas. The names by which it is known in different regions are black gum, sour gum, tupelo, pepperidge, wild pear tree, gum, and yellow gum.

The leaves of black gum are simple and alternate; not serrate. They are attached by very short petioles, which are fuzzy when young; they are a rich, brilliant green above and lighter below; rather thick, with prominent midrib. As early as the latter part of August the leaves commence to turn a gorgeous red. The flowers are greenish and inconspicuous, growing in thick cl.u.s.ters, the staminate ones small and plentiful, the pistillate ones larger. They bloom in April, May or June.

The fruit of black gum is a drupe about one and a half inches long; inside of it is a rough, oval pit; the pulp is acrid until mellowed by frost.

The bad name given to black gum by early settlers of this country has stayed with it, though the faults found with it then, should hold no longer. The pioneers were nearly all clearers of farms. They went into the woods with ax, maul, mattock, wedges and gluts, and made fields and fenced them. The fencing was as important as the clearing, for the woods were alive with hogs, cattle, and horses, and the crop was safe nowhere except behind an eight-rail staked and ridered fence. The farmer mauled the rails from timber which he cut in the clearing, and there it was that he and black gum got acquainted. The oak, chestnut, walnut, cherry, yellow poplar, and red cedar were split into rails and built into fences; but black gum never made a fence rail. No combination of maul, wedge, glut, determination, and elbow grease ever split a black gum log within the borders of the American continent. An iron wedge, driven to its head in the end of a rail cut, will not open a crack large enough to insert the point of a pocket knife. In fact, it is as easy to split the log crosswise as endwise. Consequently, the early farmers heaped their anathemas and maranathas on black gum and pa.s.sed it by.
