The soil to the depth of many feet, and from it springs the most marvellous tangle of huge trees, shrubs, bushes, underwood, creepers, climbing plants and trailing vines, the whole hung with ferns, mosses, and parasitic growths, and bound together by rattans and huge rope-like trailers.
The Malays also work jungle produce, of which the most important are gutta, rattans, agila wood, camphor wood, and the beautiful kamuning wood which is used by the natives for the hilts of their weapons.
Camphor, sugar, tea, indigo, ground peanuts, jute, hemp, oil and rattans are all articles of export.
The chief exports consist of rice, rattans, torches, dried fish, areca-nuts, sesamum seeds, molasses, sea-slugs, edible birds' nests and tin.
The coast region is characterized by mangroves, Pandanus, rattans, and similar palms with long flexible stems, and the middle region by the great rice-fields, the coco-nut and areca palms, and the usual tropical plants of culture.
