His nose is not only the flattest, but also the smallest among the IndoChinese; his eyes are rarely oblique; his mouth is large and his lips thick; his teeth are blackened and his gums destroyed by the constant use of the betel-nut, the areca-nut and lime.
Clay-pipes may also give rise to cancer of lips in males in England, while cancer of the mouth of both sexes is common in India where chewing a mixture of betel leaves, areca-nut, tobacco and slaked lime is the usual practice.
The chief exports consist of rice, rattans, torches, dried fish, areca-nuts, sesamum seeds, molasses, sea-slugs, edible birds' nests and tin.
Areca-nut Island), the town and island which, after Singapore, form the most important portion of the crown colony of the Straits Settlements.
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.
The betel nut is the fruit of the Areca or betel palm, Areca Catechu, and the betel leaf is the produce of the betel vine or pan, Chavica Betel, a plant allied to that which yields black pepper.
The Areca palm is a native of the Malay Peninsula and Islands and is extensively cultivated over a wide area in the East, including southern India, Ceylon, Siam, the Malay Archipelago and the Philippine Islands.
The nuts of other species of Areca are used by the poorer classes in the East as substitutes for the genuine betel nut.
The alkaloid arecaidine, C7H11N02, occurs in areca or betel nuts, together with three other alkaloids: arecoline, C$H13N02, guvacine, C 6 H 9 NO 2, and arecaine, C1H11N02.
Thus the protoand per-salts of iron, as well as the protoand per-salts of tin, including also a large variety of tannin, sumac, divi-divi, chestnut, valonia, the acacias (Areca Catechu and Acacia Catechu from India), from which are obtained cutch and gambier, &c., are no longer used solely as mordants or tinctorial matters, but mainly to serve the object of converting the silk into a greatly-expanded fibre, consisting of a conglomeration of more or less of these substances."
Rice, areca-nuts, and betel-vine leaf are the chief agricultural products.
The following genera are among those most commonly cultivated: Acanthophoenix Chamaerops Martinezia Acanthorhiza Cocos Oreodoxa Areca Corypha Phoenix Bactris Geonoma Pritchardia Brahea Hyophorbe Rhapis Calamus Kentia Sabal Caryota Latania Stevensonia Ceroxylon Livistonia Thrinax Chamaedorea Ferns.
The principal cultivated plants, apart from sugar-cane and coffee, are rice (in great variety of kinds), the coco-nut palm, the areng palm, the areca and the sago palms, maize, yams, and sweet potatoes; and among the fruit trees are the Indian tamarind, pomegranate, guava, papaw, orange and lemon.
In width, covered with coco-nut and areca palms, which to a great extent constitute the wealth of the country.
Trade is large and increasing, the chief exports being copra, coir and other coco-nut products, pepper, tea, sugar, areca-nuts, timber, hides, coffee, &c. The capital is Trivandrum.
The betel-nut or areca palm is chiefly grown in certain favoured localities, such as the deltaic districts of Bengal and the highlands of southern India.
Brunei, at this time, was a dependency of Majapahit (Java), and paid a yearly tribute of a jar of areca juice obtained from the young green nuts of the areca palm, and of no monetary value.
Flora and Faunx.-Although the vegetation of the Nicobars has received much desultory attention from scientific observers, it has not been subjected to a systematic examination by the Indian Forest Department like that of the Andamans, and indeed the forests are quite inferior in economic value to those of the more northerly group; besides fruit trees - such as the coco-nut (Cocos nucifera), the betel-nut (Areca catechu), and the mellori (Pandanus leeram) - a thatching palm (Nipa fruticans) and various timber trees have some commercial value, but only one timber tree (Myristica irya)would be considered first-class in the Andamans.
The jungle tribes collect gum from several varieties of trees, and in Sind the Forest Department derives a small revenue from lac. The palms of the presidency consist of cocoa-nut, date, palmyra and areca catechu.
Gutta-percha (getah percha in the vernacular), camphor, cinnamon, cloves, nutmegs, gambir and betel, or areca-nuts, are all produced in the island; most of the tropical fruits flourish, including the much-admired but, to the uninitiated, most evil-smelling durian, a large fruit with an exceedingly strong outer covering composed of stout pyramidal spikes, which grows upon the branches of a tall tree and occasionally in falling inflicts considerable injuries upon passers-by.
Besides betel-nut (Areca Catechu), the palms of India include the coco-nut (Cocos nucifera), the bastard date (Phoenix sylvestris), the palmyra (Borassus flabellifer), and the true date (Phoenix dactylifera).
