In the swamps are the bald cypress, the white cedar and the live oak, usually draped in southern long moss; south of Cape Fear river are palmettos, magnolias, prickly ash, the American olive and mock orange; along streams in the Coastal Plain Region are the sour gum, the sweet bay and several species of oak; but the tree that is most predominant throughout the upland portion of this region is the long-leaf or southern pine.
Several other pines are found, and among the less important timber trees are black spruce, Carolina balsam, beeches, ashes, sycamore or button wood, sweet gum and lindens.
Glycerin acts as a preservative against decomposition, owing to its antiseptic qualities, which also led to its being employed to preserve untanned leather (especially during transit when exported, the hides being, moreover, kept soft and supple); to make solutions of gelatin, albumen, gum, paste, cements, &c. which will keep without decomposition; to preserve meat and other edibles; to mount anatomical preparations; to preserve vaccine lymph unchanged; and for many similar purposes.
This property is usually obtained by mixing soft and hard soaps, or, more rarely, by adding gum tragacanth to a hard soap. In the textile trades the wool scourer employs a neutral olive-oil soap, or, on account of its cheapness, a neutral curd or curd mottled brand; the cotton cleanser, on the other hand, uses an alkaline soap, but for cleaning printed cottons a neutral olive-oil curd soap is used, for, in this case, free alkali and resin are objectionable; olive-oil soap, free from caustic alkali, but often with sodium carbonate, is also used in cleansing silk fibres, although hard soaps free from resin are frequently employed for their cheapness.
There are four classes in Somaliland: (I) nomads who breed ponies, sheep, cattle and camels, live entirely on milk and meat, and follow the rains in search of grass; (2) settled Somali, comparatively few, living in or near the coasts; (3) outcast races, not organized in tribes but living scattered all over Somaliland; they are hunters, workers in iron and leather, and the chief collectors of gum and resin; (4) traders.

Where, as in private herbaria, the specimens are not liable to be handled with great frequency, a stitch here and there round the stem, tied at the back of the sheet, or slips of paper passed over the stem through two slits in the sheet and attached with gum to its back, or simply strips of gummed paper laid across the stem, may be resorted to.
Specimens on the bark of trees require pressure until the bark is dry, lest they become curled; and those growing on sand or friable soil, such as Coniocybefurfuracea, should be laid carefully on a layer of gum in the box in which they are intended to be kept.

The heat at which the syrup boils in the clarifiers, 220° F., has the property of separating a great deal of the gum still remaining in it, and thus cleansing the solution of sugar and water for crystallization in the vacuum pans; and if after skimming the syrup is run into separators or subsiders of any description, and allowed to settle down and cool before being drawn into the vacuum pan for crystallization, this cleansing process will be more thorough and the quality of the final product will be improved.
The processes of evaporation and concentration are carried on as they are in a cane sugar factory, but with this advantage, that the beet solutions are freer from gum and glucose than those obtained from sugar-canes, and are therefore easier to cook.

European fruit trees and vines flourish in certain localities, while in the drier regions the Australian wattle, gum trees and pepper trees have been introduced with success.
Buried in this clay-marl are found large deposits of the fossil resin which becomes the kauri gum of commerce; and on the surface extensive forests are still a great though diminishing source of wealth.
Kauri gum still holds its place as an export, over £500,000 worth being dug up annually.

Apart from gold-mining, coal-mining and gum-digging, the industries are still mainly the growing of food and raw material; and the occupation of the land is easily the chief of all economic questions.
In 1895 began a marked commercial revival, mainly due to the steady conversion of the colony's waste lands into pasture; the development of frozen meat and dairy exports; the continuous increase of the output of coal; the invention of gold-dredging; the revival and improvement of hemp manufacture; the exploiting of the deposits of kauri gum; the reduction in the rates of interest on mortgage money; a general rise in wages, obtained without strikes, and partially secured by law, which has increased the spending power of the working classes.
