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 competition 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 class, like furniture and interior finish. It is only
moderately strong and stiff, and is not a competitor of hickory, ash,
maple, and oak in vehicle manufacturing and other lines where strength
or elasticity is demanded; but in nearly all other classes 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 quantity of any
other species. The veneer is nearly all rotary cut, and it goes into
cheap and expensive commodities, from berry crates to pianos.
