Candle Nuts.—A small evergreen tree, the Aleurites triloba of the spurgewort family (Euphorbiaceæ). It is a native of most warm countries of the East: India, Malay, southern Japan, and nearly all the islands of the Pacific ocean, and in some of these it is cultivated for the fruit, which is about two inches in diameter. In the center there is a hard nut, very oily, with the flavor of the walnut. The oil obtained from these nuts is in common use among the natives of the Polynesian islands. In the Hawaiian group the kernels are strung on a small, dry stick, which serves the purpose of a wick, and then one end lighted, as with an ordinary tallow or wax candle, hence probably the common name of candle nut. These nuts are said to be used in the same way in India. Large quantities of oil is also expressed from them and used for various purposes, and occasionally small quantities are exported to European countries.
Cape chestnut.—The name of a beautiful evergreen ornamental tree, native of south Africa, and recently introduced into European gardens from the Cape of Good Hope, hence its common, and its specific scientific name, Calodendron capense. It belongs to the Rue family (Rutaceæ). The flowers are red, produced in long terminal racemes, the tree growing about forty feet high, and said to be one of the finest trees of that part of Africa. It is now under trial in Florida. Why called a chestnut I have been unable to discover.
[FIG. 102]. THE CASHEW NUT.
Cashew nut.—A large shrub or small tree, native of the West Indies, and for this reason often referred to as the "Western Cashew," or Anacardium occidentale. It belongs to the Terebinth family (Anacardium), consequently is closely related to our native poison sumachs (Rhus). The tree is an evergreen, with entire feather-veined leaves; flowers of a reddish color, very small, sweet-scented, and produced in terminal panicles. The fruit is kidney-shaped, and borne on a fleshy receptacle, and when ripe of reddish or yellow color. The nut proper is enclosed in a leathery covering, consisting of two layers, between which is deposited a thick, caustic, oily substance, exceedingly acrid; but this is eliminated by heat, so that when the kernels are roasted they have a pleasant flavor and are highly esteemed for dessert. Some care is required in roasting these nuts, as the fumes given off during this operation cause inflammation of the eyes. The nuts also yield an excellent oil, very similar to the best olive oil. Although originally found only in the West Indies, this nut is now widely distributed throughout the tropical countries of the East; in fact, naturalized in all hot climates, and is also under trial in southern Florida.
Caucasian walnut. Winged walnut.—The winged fruit of Pterocarya fraxinifolia, also known as P. Caucasica of nurserymen's catalogues. It belongs to the walnut family (Juglandaceæ), and is a tree growing thirty to forty feet high, somewhat resembling the common ash (Fraxinus). It is a pretty, hardy, ornamental tree, thriving only in moist soils. Seeds on winged nuts produced in long, drooping racemes, but of no special value. Introduced into England from Caucasus in 1800, and now plentiful here in nurseries.
Chestnut.—See [Chapter V]; also [Horse-chestnut], and [Moreton Bay], [Tahiti] and [Water chestnuts].
Chocolate nut or bean.—The seeds of a small tropical tree, Theobroma Cacao, of the chocolate nut family (Sterculiaceæ). Indigenous to tropical America, but now cultivated more or less extensively in all hot climates. The tree grows from fifteen to twenty feet high, with long, pointed, smooth leaves. The flowers are small, yellow, and produced from the old wood of both stems and branches, succeeded by a pod-like fruit six to ten or more inches long, containing fifty to a hundred seeds, resembling beans more than they do nuts. When the fruit is ripe it is gathered, at which time the seeds are covered with a gum-like substance, and to remove this they are subjected to a slight fermentation, after which they are dried in the sun, this giving them their usual brown color. Chocolate nut trees are extensively cultivated in Brazil, New Grenada, Trinidad, and, in fact, throughout tropical America, and their cultivation is, upon the whole, very profitable, as the demand is almost unlimited.
Clearing nut.—This is an East India name for the seeds of Strychnos potatorum, a plant belonging to the well-known nux vomica family (Loganiaceæ). It is a small tree, native of India, the wood of which is used for various purposes. The fruit is about the size of a cherry, and contains one seed; this is dried, and used for clearing muddy water, this being effected by rubbing one of the little nuts around the sides of the vessel that is to be filled, after which the water is poured in, and then, through some unknown agency, all the foreign matter settles, leaving the liquid perfectly pure, clear and wholesome.
Cocoanut.—One of the most widely-known and largest of edible nuts; the product of Cocos nucifera, a lofty, tree-like palm (Palmæ or Palmaceæ). It is a native of tropical Africa, India, Malay, and of nearly all the islands of the Indian and Pacific oceans. It only thrives near the seacoast or where the sea breezes reach it, requiring no special care after the nuts and young plants once become established in a congenial soil. The coco palm grows from fifty to one hundred feet high, with pinnate leaves from ten to twenty feet long. The nuts are produced in clusters of a dozen or more, and when full grown are somewhat triangular and a foot long, the outer coat or husk composed of a tough fiber. The nuts, when cleaned of their husks, are too well known to call for a further description here. In countries where these nuts are plentiful, their contents form nearly the entire food of the natives, the milky fluid serving for drink, and the more solid parts as a substitute for meat and bread. The cocoa-nut utilized in more ways, and for a greater variety of purposes, than any other kind known, and it would require a volume to briefly enumerate them. Of recent years there have been plantations made of this nut on the coast of southern Florida, and one of the most extensive of these is by a man from New Jersey, but I have not heard from him of late, or seen any reports as to the results of his experiments. It is reported that there are about 250,000 cocoa-nut trees now growing in Florida.
