Chapter XXXII: Section II (10)

The cassava root grows abundantly in most of the West India islands and tropical America; the trouble of planting is inconsiderable, and the profit arising from its manufacture, even by the common process of hand-grating, is immense. I should be glad if I could induce the enterprising of our colonial settlers to give this a fair trial, as well as encourage the present growers to increase their crops and improve the quality of the article, so as to render it suitable for the English market. The manufacture of starch will one of these days become a productive source of colonial wealth. Since cassava was first grown in the West, its capabilities as a starch-producer have, to a certain extent, been known, and for that purpose it has been in limited use.

Mr. James Glen, of Haagsbosch plantation, Demerara, has recently tested its value as an article of export, and added it to the other industrial resources of that colony.

This gentleman, by erecting machinery on his plantation for grinding the root and preparing the starch of the bitter cassava, has already shipped the article in considerable quantities to Europe, and it has been sold at a price which puts the profit upon sugar cultivation completely to the blush. His agent in Glasgow writes, that any quantity (like that already shipped) can command a ready sale at 9d. per lb. Its use is co-extensive, or nearly so, with that of sugar. The productive capabilities of the soil are not perhaps generally known; nor is it necessary that, to pay the grower there, it should bring even half that price. A sample of a ton, which was prepared at Haagsbosch in 1841, was submitted for examination to Dr. Shier, at the colonial laboratory, Georgetown, who admitted it to be a beautiful specimen of starch, although it had undergone but _one_ washing. The root from which it was made, was planted eight or nine months previously, upon an acre of soil, which had never undergone any preparation of ploughing, or been broken and turned up in any way. The plants were never weeded after they had begun to spring, nor were they tended or disturbed until they were ripe and pulled up. The expense of planting the acre was five dollars, and reaping this crop would, I suppose, amount to as much more, say £2 in all. The green cassava was never weighed, but the acre yielded fully a ton of starch--equal, at 9d. per lb., to £84.

The experimental researches of Dr. Shier have led him to believe that the green bitter cassava will give one-fifth its weight of starch. If this be the case the return per acre would, under favorable circumstances, when the land is properly worked, be enormous. On an estate at Essequibo, a short time ago, an acre of cassava, grown in fine permeable soil, was lifted and weighed; it yielded 25 tons of green cassava. Such a return as this per acre would enable our West India colonies to inundate Great Britain with food, and at a rate which would make flour to be considered a luxury. Dr. Shier is convinced that, in thorough drained land, where the roots could penetrate the soil, and where its permeability would permit of their indefinite expansion, a return of 25 tons an acre might uniformly be calculated upon. What a blessing, not only for those colonies, but for the world, would the introduction be of this cheap and nutritious substitute for the potato.

NEW TUBEROUS PLANTS RECOMMENDED AS SUBSTITUTES FOR THE POTATO.

In the present disturbed state of the grain markets of Europe, the advantage of cultivating plants which directly or indirectly can form a substitute for the potato, admits of no doubt. It appears to me, moreover, that when the way is once opened up, even under ordinary circumstances, the tropical colonies of Great Britain, without diminishing the quantity of sugar and coffee they produce, could advantageously supply the British market with the purest starches, and possibly also with various other articles of farinaceous food. Anything that will lead the planters to a more varied cultivation than the present uniform and persistent one, will be advantageous to our colonies; and the growth of farinaceous root crops for exportation, cannot fail to produce most beneficial effects on that class of the peasantry in the British possessions, who are owners of small lots of land, which at present they either totally neglect, or cultivate most imperfectly.

In 1846, Dr. A. Gesner, one of my correspondents, called attention, in my "Colonial Magazine," to two indigenous roots of North America, which he thought deserving special attention. These were _Apios tuberosa_, and _Claytonia acutiflora_, _or Virginiana_.

1. _A. tuberosa_ (Boerhave), or _Glycine Apios_.--This plant is common throughout the Northern and Southern States of America, and is also met with in the lower British North American Provinces. It is known under the native name of _Saa-ga-ban_ by the Micmac Indians, by whom the pear-shaped roots are used as an article of food. Like the _Arachis hypogæa_, it belongs to the Leguminosæ family. The fruit and flower resemble those of the wood vetch. It is thus described in Professor Eaton's "Manual of Botany for North America," published in 1836:--"Color of corolla, blue and purple; time of flowering, July (and August in Nova Scotia), perennial; stem, twining; leaves, pinnate, with seven lance-ovate leaflets; racemes shorter than the leaves, axillary; root, tuberous. Root very nutritive; ought to be generally cultivated."

The average size of the tubers is that of cherries, but a few are found of much larger dimensions. In their appearance they resemble the common potato, having apparently the peculiar indentations called eyes. The skin of the tuber is of a rusty or blackish brown color. The interior is very white, and the root has the taste and odor of the common potato. The Indians state that the roots, if kept either in a dry or moist state, will not suffer any decay for a lengthened period. They are very farinaceous, and contain a large per centage of starch, which resembles that of wheat; by being dried the tuber shrinks a little, but it immediately expands on being thrown into warm water. It contains much nutritive matter, is wholesome, and I have no doubt, if properly cultivated, it will prove to be very prolific. The tubers are situated a few inches below the surface of the soil, and are strung together like beads by a strong ligament.

A similar kind of earth-nut, or tuberous root, probably the _Glycine subterranea_ of Linnæus, the Voandzou of Madagascar, is extensively cultivated in various parts of Africa.

2. _Claytonia acutiflora_ or _Virginiana_, the Musquash of the Micmac Indians, is found throughout the Northern and Southern States of North America. It is thus described by Prof. Eaton, "Man. Bot. N.A."--"Color of corolla, white and red; situation, alpine, perennial; leaves, linear, lance-ovate; petals, obovate, retuse; leaves of the calyx, somewhat acute; root, tuberous. It blossoms in May. The seed is ripe in June, when the plant disappears."

These roots may be collected along the sea coasts and principal lakes and rivers of Nova Scotia, New Brunswick, and Prince Edward's Island, although they are not plentiful, for they are greedily devoured by some of the wild animals, and wherever swine have been permitted to run at large they have been destroyed.

Dr. Gesner shipped several bushels of the saa-ga-ban to the principal agricultural societies in Great Britain, also to Halifax, and Nova Scotia. The ordinary potato of this country does not yield more than 14 per cent. of starch, and it contains 76 per cent. of water. From the best saa-ga-ban Dr. Gesner obtained 21 per cent. of starch, and the quantity of water is reduced to 50 per cent. It also contains vegetable albumen, gum, and sugar. From these facts it is evident that the saa-ga-ban is much more nutritive than the potato, and the weight of the tubers, in their wild state, compared with the weight of the slender vine in the best samples, is equal in proportion to the common cultivated potato in its ordinary growth. The starch is very white, and closely resembles that made from the arrowroot. It is not improbable that the quantity of water in the tuber will be increased by cultivation; yet the fibrous parenchyma will be reduced, and taken altogether, the nutritive properties will be increased; if the plant improve as much by cultivation as the potato and many others have done, its success is certain.

The North American Indians have several wild roots which they dig up for sustenance when other food is exhausted. Among these are--1st, the mendo, or wild sweet potato; 2nd, the tip-sin-ah, or wild prairie turnip; 3rd, the omen-e-chah, or wild bean. The first is found throughout the valleys of the Mississippi and St. Peter's, about the basis of bluffs, in rather moist but soft and rich ground. The plant resembles the sweet potato, and the root is similar in taste and growth. It does not grow so large or long as the cultivated sweet potato, but I should have thought it the same, were it not that the wild potato is not affected by the frost. A woman will dig from a peck to half a bushel a day.

The Indians eat them, simply boiled in water, but prefer them cooked with fat meat.

The wild potato, of the north-west of America, is a general article of food; it is called by them wabessepin; it resembles the common potato, is mealy when boiled, and grows only in wet clay ground, about one and a half feet deep. The crane potato, called sitchauc-wabessepin, is of the same kind, but inferior in quality. The Indians use these for food as well as the memomine, and another long and slender root called watappinee. Probably it is the first of these that is referred to by Nicollet, as the prairie potato. "All the high prairies (he says) abound with the silver-leafed _Psoralia_, which is the prairie turnip of the Americans, the _pomme des prairies_ of the Canadians, and furnishes an invaluable food to the Indians." There are several species of _Psoralia_, viz., _esculenta_, _argophylla_, _cuspidata_, and _lanceolata_.

The prairie turnip grows on the high dry prairies, one or two together, in size from that of a small hen's egg to that of a goose egg, and of the same form. They have a thick black or brown bark, but are nearly pure white inside, with very little moisture. They are met with four to eight inches below the surface, and are dug by the women with a long pointed stick, forced into the ground and used as a lever. They are eaten boiled and mashed like a turnip, or are split open and dried for future use. In this state they resemble pieces of chalk. It is said that when thus dried they may be ground into flour, and that they make a very palatable and nutritious bread. M. Lamare Picot, a French naturalist, has lately incurred a very considerable expense to obtain the seed, which he has carried to France, believing that it is capable of cultivation, and may form a substitute both for potato and wheat.

The wild bean is found in all parts of the valleys where the land is moist and rich. It is of the size of a large white bean, with a rich and very pleasant flavor. When used in a stew, I have thought it superior to any garden vegetable I had ever tasted. The Indians are very fond of them, and pigeons get fat on them in spring. The plant is a slender vine, from two to four feet in height, with small pods two to three inches long, containing three to five small beans. The pod dries and opens, the beans fall to the ground, and in spring take root and grow again. The beans on the ground are gathered by the Indians, who sometimes find a peck at once, gathered by mice for their winter store.

There are also several kinds of edible roots growing in the ponds or small lakes, which are gathered by the Indians for food.

The _psui-cinh-chah_, or swamp potato, is found in mud and water, about three feet deep. The leaf is as large as the cabbage leaf. The stem has but one leaf, which has, as it were, two horns or points. The root is obtained by the Indian women; they wade into the water and loosen the root with their feet, which then floats, and is picked up and thrown into a canoe. It is of an oblong shape, of a whitish yellow, with four black rings around it, of a slightly pungent taste, and not disagreeable when eaten with salt or meat.

The _psui-chah_, with a stem and leaf similar to the last, has a root about the size of a large hickory-nut. They grow in deep water, and being smaller are much more difficult to get, but the Indians prefer them; they have an agreeable taste, and are harder and firmer when cooked. Both these roots are found in large quantities in the musk-rat lodges, stored by them for winter use.

The _ta-wah-pah_, with a stem, leaf, and yellow flower, like the pond-lily, is found in the lakes, in water and mud, from four to five feet deep. The Indian women dive for them, and frequently obtain as many as they are able to carry. The root is from one to two feet in height, very porous; there are as many as six or eight cells running the whole length of the root. It is very difficult to describe the flavor. It is slightly sweet and glutinous, and is generally boiled with wild fowl, but is occasionally roasted.

In his exploring expedition into the interior of Guiana, in the region of the Upper Essequibo, Sir E. Schomburgk notices the discovery of a variety of Leguminosæ, whose tubers grow to an enormous size, fully equal to the largest yam. These roots were not, at the time he was there, in full perfection, but their taste was somewhat between the yam and the sweet potato. The Taruma Indians called them Cuyupa. The roots are considered fit for use when the herb above ground dies. Sir Robert brought a few of the seeds of the plant with him on his return to Demerara.

Two interesting productions have been recently introduced into the Jardin des Plantes, at Paris, from the Ecuador, by M. Bourcier, formerly Consul-General of France in that country. One is the red and yellow _ocas_, which is of the form of a long potato, and has the taste of a chesnut; the other is the _milloco_, which has the taste and form of our best potatoes. These two roots, which are found in great abundance in the neighbourhood of Quito, grow readily in the poorest land. The _oca_ is cultivated in the fields of Mexico, but only succeeds in the warmer districts. From the bulbous roots of the cacomite, a species of _Tigridia_, a good flour is also prepared there.

Stevenson ("Travels in South America," vol. ii., p. 55) says, a root called the oca is cultivated in several of the colder provinces of Peru. "This plant," he states, "is of a moderate size, in appearance somewhat like the acetous trefoil; the roots yellow, each about five or six inches long, and two in circumference. They have many eyes, and the roots, several of which are yielded by one plant, are somewhat curved. When boiled it is much sweeter than the camote or batata; indeed it appears to contain more saccharine matter than any root I ever tasted; if eaten raw it is very much like the chesnut. The roots may be kept for many months in a dry place. The transplanting of the oca (he adds) to England, where I am persuaded it would prosper, would add another agreeable and useful esculent to our tables."

The Brussels paper, _L'Emancipation_, mentions that a root has been discovered by the Director of the Museum of Industry, in that place, destined to take the place of the potato. It is the _Lathyrus tuberosus_, called by the peasants the earth mouse, on account of its form, and the earth chesnut on account of its taste. This plant exists only in some localities of Lorraine and Burgundy. The Lathyrus has never been cultivated, and it is thought that it will attain, with cultivation, the size of the potato. The French peasants have a prejudice against cultivating it, because they say it walks under ground, and leaves the place it is planted in to go into the neighbouring field. The fact is, that it grows in a chaplet, of which the bulbs are arranged along a root running horizontally, of which the two extremities are very rarely found, so that on taking up the hinder tubercles it continues its growth in front, which gives rise to the saying that if the plant had only time enough, it would make the tour of the world.

The bulb of _Gastrodia sesamoides_ (R. Brown), a curious herbaceous species of orchis, native of New Holland, is edible, and preferred by the aborigines to potatoes and other tuberous roots. Some of my accredited informants believe it might be turned to profitable account, but being a parasitic plant, it could scarcely be systematically cultivated. It flourishes in its wild state on loamy soil in low or sloping grounds. The first indication of its vegetation in the spring, is the appearance of a whitish bulb above the sward, of an hemispherical shape, and about the size of a small egg. The dusky white covering resembles a fine white net, and within it is a pellucid gelatinous substance. Again within this is a firm kernel, about as large as a Spanish nut, and from this a fine fibrous root descends into the soil. It is known in Van Diemen's Land, and other parts of Australia, by the common name of native bread. Captain Hunter, in his Journal of the Transactions at Port Jackson on the first settlement of the Convict Colony, speaks of finding large quantities of "wild yams," on which the natives fed, but the roots were not bigger than a walnut; therefore it was probably this plant.

_Arracacha esculenta_, of Bancroft and Decandolle (_Conium Arracacha_).--This perennial herb is a native of South America, which, from its salubrious qualities, is extensively cultivated in the mountains of Venezuela and other parts of tropical and Southern America, for culinary purposes. It is propagated by planting pieces of the tuberous root, in each of which is an eye or shoot. The late Baron de Shack introduced it into Trinidad, from Caraccas, and it has thence been carried to the island of Grenada. It throve there remarkably well, but has been unaccountably neglected. He also sent roots of this valuable plant to London, Liverpool, and Glasgow. Although it bears cold better than the potato, it requires a warmer and more equal temperature than most of the countries of Europe afford. It would, however, make an excellent addition to the culinary vegetables of many tropical countries, uniting the taste of the potato and parsnip, but being superior to both.

The arracacha has been introduced into the South of Europe, not as a substitute for, but as a provision against a failure of the potato crop. It is highly recommended by the Rev. J.M. Wilson, in the "Rural Encyclopædia."

Stevenson ("Travels in South America," vol. ii., p. 383) says the yucas (cassava), camotes (sweet potatoes), and yams cultivated at Esmeraldas and that neighbourhood, were the finest he ever saw. "It is not uncommon for one of these roots to weigh upwards of twenty pounds. At one place I saw a few plants of the yuca that had stood upwards of twenty years, the owner having frequently bared the bottom of the plants and taken the ripe roots, after which, throwing up the earth again, and allowing a sufficient time for new roots to grow, a continual succession of this excellent nutritious food was procured."

The Aipi grows in Brazil, and according to T. Ashe, may be eaten raw, and, when pressed, yields a pleasant juice for drink; or being inspissated by the heat of the sun, is kept either to be boiled and eaten, or dissolved and drank. The tapinambar grows in Chili, and is used by the Indians.

The tapioca, or bay rash, a plant which grows about the out-islands of the Bahamas group, was found of great use as a food plant to the inhabitants of Long Island, during a scarcity of food occasioned by the drought in 1843. This root grows in the form of a large beet, and is from twelve to sixteen inches in length. It is entirely farinaceous, and, when properly ground and prepared, makes good bread. It fetches there four to six cents a pound.

The root of the kooyah plant (_Valeriana edulis_) is much used by some of the North American Indians as food. The root is of a very bright yellow color, with a peculiar taste and odor, and hence is called "tobacco root." It is deprived of its strong poisonous qualities by being baked in the ground for about two days. A variety of other roots and tubers furnish them with food. Among these are kamas root (_Camassia esculenta_), which is highly esteemed; the bulb has a sweet pleasant flavor, somewhat of the taste of preserved quince. It is a strikingly handsome bulbous plant, with large beautiful purple flowers. Yampah root (_Anethum graveolens_) is a common article of food with the Indians of the Rocky Mountains.

The roots of a thistle (_Cersium virginianium_, or _Carduus virginianus_), which are about the ordinary size of carrots, are also eaten by them. They are sweet and well flavored, but require a long preparation to fit them for use.

The people of Southern India and Ceylon have for many hundred years been in the habit of eating the bulb or root, which is the first shoot from the Palmyra nut, which forms the germ of the future tree, and is known locally as _Pannam kilingoes_. It is about the size of a common carrot, though nearly white. It forms a great article of food among the natives for several months in the year; but Europeans dislike it from its being very bitter. Recent experiments have proved that a farina superior to arrowroot can be obtained from it, prepared in the same way; and 100 roots, costing 2½d., yield one and a-half to two pounds of the flour.

From the boiled inner bark of the Russian larch, mixed with rye flour, and afterwards buried a few hours in the snow, the hardy Siberian hunters prepare a sort of leaven, with which they supply the place of common leaven when the latter is destroyed, as it frequently is by the intense cold. The bark is nearly as valuable as oak bark. From the inner bark the Russians manufacture fine white gloves, not inferior to those made of the most delicate chamois, while they are stronger, cooler, and more pleasant for wearing in the summer.

The fruit of the _Cycas angulata_ forms the principal food of the Australian aborigines during a portion of the year. They cut it into thin slices, which are first dried, afterwards soaked in water, and finally packed up in sheets of tea-tree bark. In this condition it undergoes a species of fermentation; the deleterious properties of the fruit are destroyed, and a mealy substance with a musty flavor remains, which the blacks probably bake into cakes. They appear also to like the fruit of the _Pandanus_, of which large quantities were found by Dr. Leichardt in their camps, soaking in water, contained in vessels formed of stringy bark.

The flour obtained from the seeds of Spurry (_Spergula sativa_), when mixed with that of wheat or rye, produces wholesome bread, for which purpose it is often used in Norway and Gothland. In New Zealand, before the introduction of the potato, the roots of the fern were largely consumed.

Many species of _Bolitus_ are used as food by the natives in Western Australia, according to Drummond.

The thick tuberous roots of a climbing species of bean (_Pachyrhizus angulatus_, or _Dolichos bulbosus_) are cultivated and eaten in some parts of the Polynesian islands. The bulbous roots of some species of Orchideæ are eagerly sought after in New South Wales by the natives, being termed "boyams," and highly esteemed as an article of food for the viscid mucilage which they contain. The root of the Berar (_Caladium costatum_) is eaten by the natives of the Pedir coast (Achin), after being well washed.

The pignons or edible seeds of _Pinus Pinea_ are consumed occasionally in Italy. In Chili the cone or fruit of the _pehuen_, or _pino de la tierra_, are considered a great delicacy. The _pinones_ are sometimes boiled, and afterwards, by grinding them on a stone, converted into a kind of paste, from which very delicate pastry is made. The pine is cultivated in different parts of this province on account of its valuable wood and the pinones. The seeds from the cones of the Auracanean pine, collected in autumn, furnish the Pawenches (from _pawen_ pine) and Auracanians with a very nutritious food. When cooked, the flavor is not unlike that of the chesnut, and as they will keep for some time, they constitute, when the gathering season has been favorable, a great part of their diet.

The seeds of the cones of the nut pine (_Pinus monophyllus_), a new species described by Dr. Torrey, and alluded to by Col. Fremont in his exploring expedition to the Rocky Mountains, are largely used by the North American Indians. The nut is oily, of a most agreeable flavor, and must be very nutritious as it constitutes the principal subsistence of many of the native tribes.

The cone of another magnificent pine (_Auracaria Bidwillii_), indigenous to the Eastern coast of Australia, about the Moreton Bay district, is frequently met with twelve inches in diameter, and containing 150 edible seeds as large as a walnut. The aborigines roast these seeds, crack the husk between two stones, and eat them hot. They taste something like a yam or hard dry potato. The trees bear cones only once in four years, during a period of six months. This season is held as a great festival by the aborigines of that locality, called by them Bunga Bunga, and they congregate in greater numbers than is known in any other part of Australia, frequently coming from a distance of 300 miles. They grow sleek and fat upon this diet. An Act has been passed by the legislature of the colony, prohibiting, under heavy pains and penalties, the demolition of those trees, being the natural food of the natives.

The common people eat the seeds of the red sandal wood (_Adenanthera Pavonina_) in the South of India. The pulp of the fruit of the _Adansonia digitata_, or monkey bread, is also used as an article of food.

SINGHARA OR WATER NUTS.--The large seeds of _Trapa bicornis_, a native of China, and of _T. bispinosa_ and _natans_, species indigenous to India, are sweet and eatable, and the aquatic plants which furnish them are hence an extensive article of cultivation. In Cashmere and other parts of the East they are common food, and known under the name of Singhara nuts. In Cashmere the government obtains from these nuts £12,000 of annual revenue. Mr. Moorcroft mentions that Runjeet Sing derived nearly the same sum. From 96,000 to 128,000 loads of this nut are yielded annually by the lake of Ooller alone. The nut abounds in fecula. In China the kernel is used as an article of food, being roasted or boiled like the potato. The seeds of various species of _Nelumbium_, natives of the East Indies, Jamaica, and the United States, also form articles of food. The fruit of _N. speciosum_ is supposed to be the Egyptian bean of Pythagoras. The petioles and peduncles contain numerous spiral vessels, which have been used for wicks of candles. The fruit of _Willughbeia edulis_, a native of the East, as its name implies, is eatable. The kernel of the mango can be reduced to an excellent flour for making bread.

Not only from the Lichen tribe, but also from the Algæ, fungi, mosses and ferns man derives nutriment and valuable products. Some of the cryptogamic plants form considerable articles of commerce, particularly as food plants, affording gelatinous and amylaceous matter, and being useful in medicine and the arts.

_Nostoe eduli_ is used in China as food; _Gelidium corneum_ enters into the formation of the edible swallows' nests of the Japanese islands. Agar-agar moss is shipped from Singapore to the extent of 13,000 tons a-year. Irish moss, Iceland moss, Ceylon moss, and some others, are also of some importance. Iodine and kelp are prepared to a considerable extent from sea weeds; one species (_Fucus tenax_) furnishes large supplies of glue to the Canton market, and the orchilla weed is of great importance to the dyer. It is principally as food that I have to speak of them in this section.

In some of the islands off the Scotch coasts, sea-wrack (_Fucus vesiculosus_) forms the chief support of horses and cattle in the winter months. _F. serratus_ is similarly employed in Norway.

The _Laminaria saccharina_ is interesting from the fact of its containing sugar. It is highly esteemed in Japan, where it is extensively used as an article of diet, being first washed in cold water and then boiled in milk or broth.

CARRAGEEN, or IRISH ROCK MOSS, _Sphæroccus_ (_Chondus_) _crispus_, abounds on the Western Coast of Ireland, round the Orkneys, Hebrides, Scilly Islands, &c. It is purplish white, and nearly transparent, and is largely imported to feed cattle and pigs in Yorkshire. It is also used for dressing the warp of webs in the loom, and mixing with the pulp for sizing paper in the vat. It swells up like tragacanth in water; and, by long decoction, affords a considerable quantity of a light, nutritious, but nauseous jelly. It is sometimes sold as pearl moss, and is employed in the place of gelatine or isinglass for preparing blanc-manges, jellies, &c. It fetches about £7 the ton.

AGAR-AGAR, a sort of edible seaweed, or tripe de roche, is found growing on the rocks about the eastern islands that are covered by the tide. It is much used for making a kind of jelly, which is highly esteemed both by Europeans and natives for the delicacy of its flavor. The first quality is worth about 30s. the picul (133 lbs.). An inferior kind is collected on the submerged banks in the neighbourhood of Macassar (Celebes), by the Bajow Laut, or Sea Gipsies. It is also collected on the rocks about the settlement of Singapore, for export to China, where it is much used as a size for stiffening silks and for making jellies. It constitutes the bulk of the cargoes of the Chinese junks on their return voyage. The quantity shipped from Singapore is about 10,000 piculs (12,500 tons) annually.

ICELAND MOSS (_Cetraria islandica_) combines valuable alimentary and medicinal properties. It is imported in bags and barrels from Hamburg and Gothenburg, and is said to be the produce of Norway and Iceland. The quantity consumed varies; in 1836, 20,599 lbs. paid duty; in 1840, 6,462 lbs. In Carniola, swine, oxen, and horses, are fattened on it. Boiled in water or milk, and flavored to the palate with sugar, wine, and aromatics, it forms a very agreeable diet for invalids.

CEYLON MOSS (_Gracelaria_, or _Gigartina, lichenoides_), a small and delicate fucus, is well known for the amylaceous property it possesses, and the large proportion of true starch it furnishes. The fronds are filiform; the filaments much branched, and of a light purple color. It grows abundantly in the large lake or back-water which extends between Putlam and Calpentyr, Ceylon. It is collected by the natives principally during the south-west monsoon, when it becomes separated by the agitation of the water. The moss is spread on mats and dried in the sun for two or three days. It is then washed several times in fresh water, and again exposed to the sun, which bleaches it, after which it is collected in heaps for exportation.

Professor O'Shaughnessy has given the best analysis of this moss, which he described under the name of _Fucus amylaceus_; 100 grains weight yielded the following proportions:--

Vegetable jelly 54.50
True starch 15.00
Ligneous fibre 18.00
Sulphate and muriate of soda 6.50
Gum 4.00
Sulphate and phosphate of lime 1.00
-----
Total 99.00
With a trace of wax and iron.

I observe among the imports into New Orleans, 911 bushels of Spanish moss in 1849, and 1,394 bushels in 1848. I do not know precisely its use, or from whence derived, but I believe it is chiefly used for stuffing cushions, mattresses, &c.

FERN.--The rhizome of _Pteris esculenta_ is used as food in Australia, and that of _Marattia alata_ in the Sandwich Islands. The trunks of the _Alsophila_, or tree fern, of the western side of Van Diemen's Land, and of the common tree fern, _Cibotium Billardieri_ (the _Dicksonia antarctica_, of Labillardiere), contain the edible pith or bread-fruit eaten by the natives. Many other species of ferns are esculent. Typha bread is prepared in Scinde from the pollen of the flowers of the _Typha elephantina_, and in New Zealand from another species of bulrush (_Typha utilis_).

"It must not be supposed, as some have believed, that the fern root, wherever it grows, is fit for food. On the contrary, it is only that found in rich loose soils which contains fecula in sufficient quantity for this purpose: in poorer ground the root contains proportionally more fibre. We were now encamped on an alluvial flat in the valley of the river, thirty or forty feet below the general level of the plain; and I observed that, even in this favourable spot, a great deal of discrimination was used in selecting the best roots, which was discoverable by their being crisp enough to break easily when bent: those which would not stand this test being thrown aside. Here a quantity sufficient for several days was procured, and was packed in baskets, to last till another spot equally favourable could be reached.

"The process of cooking fern root is very simple; for it is merely roasted on the fire, and afterwards bruised by means of a flat stone similar to a cobbler's lap-stone, and a wooden pestle. The long fibres which run like wires through the root are then easily drawn out; and the remainder is pounded till it acquires the consistence of tough dough, in which state it is eaten, its taste being very like that of cassava bread. Sometimes it is sweetened with the juice of the 'tutu.'

"The natives consider that there is no better food than this for a traveller, as it both appeases the cravings of hunger for a longer period than their other ordinary food, and renders the body less sensible to the fatigue of a long march. It is in this respect to the human frame, what oats or beans are to the horse. They have a song in praise of this root, which I have once or twice heard chanted on occasions of festivals, by a troop of young women who carry baskets of the food intended for the guests."--("Shortland's New Zealand.")

I ought not to omit noticing the _Tuber cibarium_, a plant of the mushroom family, growing under ground, which furnishes the famous truffle, so celebrated in the annals of cooking, of which immense quantities are imported, chiefly from the South of France. It is common also in Italy and Germany, and is often found in Northamptonshire, and some other of our own counties. The "kemmayes," a desert plant of the truffle kind, is a great favorite with the Arabs.

In Terra del Fuego the only vegetable food of the natives, besides a few berries of a dwarf arbutus, is a species of globular bright yellow fungus (_Cyttaria Darwinii_), which grows in vast numbers on the beech trees. In its tough and mature state it is collected in large quantities by the women and children, and eaten uncooked. It has a slightly sweet mucilaginous taste, with a faint smell like that of a mushroom.
