If, instead of toddy or vinegar, sugar is required, it can be readily made from the palm sap, which, for this purpose, is treated before fermentation. It is, on being drawn from the tree, boiled in a suitable pot or other vessel until it becomes thick and stringy; a little lime is added; rough crystallisation takes place, and “jaggery,” or palm sugar, is the result. Cocoa-nut oil is valuable for a great number of purposes. It is obtained from the ripe or mature nut in a variety of ways. The natives of many of the islands of the Eastern seas cut the kernels of the nuts in pieces, boil them with water in a large kettle; collect such oil as rises to the top with a sea-shell mounted on the end of a stick; then pound the boiled nut in a mortar made from a piece of hollow log with a wooden pestle; reboil the paste thus formed; skim again, and so on. The mills used for the expression of this and other oils, and the crushing of sugar-canes, we shall describe as our work proceeds. The shell of the cocoa-nut makes excellent cups and bottles. To extract the kernel to form the latter, the natives bore out one of the eyes, pour out the milk, fill the nut with sea-water, and bury it in the sand exposed to the sun’s rays. In a short time decomposition is set up, and all the contents of the shell can be easily shaken out at the eyehole.
The fibrous husk from time immemorial has supplied the native craft of India, as well as our vessels trading there, with a cheap and generally useful kind of rope, called coir, which possesses the valuable property of being so light as to be of much less specific gravity than water, and which is, therefore, much used for buoy ropes, life lines, warps, and cables, and the ropes for the upper edges of fishing nets. Hats, bags, baskets, sandals, and many other things, are made from it; its leaves form the covering of huts, and its leaf-stalk form their framework, and serve any purpose for which light elastic wands are required.
The date palm, both wild and cultivated, furnishes fruit more or less delicious according to the species from which it is taken. The Arab and his horse, and camel too, upon emergency, will live upon it; and without it the deserts, to which it is indigenous, would be uninhabitable.
An African species (Œleis guianensis) affords palm oil, which is the basis of our candles. A vessel taking in palm oil once started it into a tank built in the hold, but the task of digging it out when it reached England was so arduous that nothing was saved by not providing casks.
Sago is the produce of a palm, which in the East yields the food of thousands; it is the pithy centre of the stem, requiring scarcely any preparation to fit it for food, and a single tree sometimes yields 600lb. weight. Those which furnish the so-called cane for chair bottoms are a species of calamus; they hang on trees by long hooked spines, and are sometimes 600ft. or 1000ft. long. These are often used as stays or standing rigging among native vessels, and sometimes we believe as cables. When split into smaller sections and twisted they form tolerable, but not perfectly flexible, ropes; and slips of them, as is well known, are commonly used by the Chinese for tying up various packages. The helmet which we wore through the Indian campaign is composed of this material closely woven.
Many varieties all over the world yield a sugary sap from their yet unopened spathes or from their stems, and this, when partly fermented, is the palm wine of Africa and, as we have shown, the toddy of the East Indies; while similar beverages are obtained by the South Americans from the Mauritia oinifera and others.
A nation at the mouth of the Orinoco River live almost entirely on a palm (probably Mauritia flexuosa); they build their houses elevated on the trunks, and live upon the fruit, sap, and such fish as the waters around them may afford.
Resins and wax are produced by some species. The fruits of a calamus, in the Eastern Archipelago, are covered with a red resinous substance, which, in common with the produce of other trees, is the dragon’s blood of commerce, and is used as a colour, a varnish, and in tooth powder.
The Ceroxylon audicola, a lofty palm growing in the Andes of Bogota, secretes in its stem a resinous wax, used for making candles. In the north of Brazil, the Carnauba (Copernicia cerifera) has the underside of its leaves covered with pure white wax, with no admixture of resin.
Thatch for houses, awnings for boats, and even the upper streaks of large canoes, umbrellas, hats, baskets, water buckets, cordage, and numberless other things, are made of palm leaves. In Cuba the Chamærops argentica, and in Sicily the Chamærops humilis, is used for making hats and other fine work. In India the place of the papyrus was supplied by palm leaves, on whose hard and glossy surfaces Pali and Sanscrit characters were inscribed with a metal point; the leaves of Corypha talieri, strung together, form the Hindoo volume. The fruit of Areca catechu is the betel nut, the favourite stimulant of the Eastern people, which they chew with lime. The fibre of the piassaba palm is made into cheap and durable cables on the Amazon, and is introduced into England in the form of brooms, &c.
