According to the calculation of Baron Von Humboldt, 6000 plants are _agamous_, that is, plants which have no s.e.xual organs, such as champignons, lichens, &c. Of the remainder there are found--

In Europe 7,000 In the temperate regions of Asia 1,500 In Equinoxial Asia, and the adjacent Islands 4,500 In Africa 3,000 In the temperate regions of America, in both hemispheres 4,000 In Equinoxial America 13,000 In New Holland, and the Islands of the Pacific Ocean 5,000 ------ Total 38,000 ------

SENSIBILITY OF PLANTS.--There are certain motions observable in plants, that make it doubtful whether they are not possessed of sensibility. Some plants shrink and contract their leaves upon being touched; others open and shut their flowers at certain fixed hours in the day, so regularly as to denote with precision the time of day; some a.s.sume a peculiar form during the night, folding up their leaves; and these different changes take place whether they are in the open air, or shut up in close apartments. Those which live under water during the time of fecundation, raise their flowers above the surface.

The motions of a marshy plant discovered some time since, in the province of Carolina, are still more singular. Its round leaves are furnished above, and on the sides, with a mult.i.tude of notches that are extremely irritable. When an insect happens to creep upon the superior surface of the leaves, they fold up, and inclose the insect till it dies; the leaves then open of themselves. We may daily observe regular motions in some plants in our gardens. Tulips expand their petals when the weather is fine, and close them again at sun-set, or during rain. Vegetables with pods, such as peas and beans, open their sh.e.l.ls when dry, and curl themselves up like shavings of wood. Wild oats, when placed upon a table, will move spontaneously, more especially if warmed in the hand. And the heliotrope, or sunflower, with various other plants, always turns towards the sun. These are incontestable facts, of the certainty of which every person may be easily convinced. From them, some conclude that we ought not to deny sensibility to be an attribute of plants; and certainly the facts which are alleged in favour of such an opinion, give it great appearance of probability. But, on the other hand, plants have no other sign of sensibility; and all that they have is entirely mechanical. We plant a shrub and destroy it, without finding any a.n.a.logy between it and an animal, that we bring up and kill. We see a plant bud, blossom, and bear seed, insensibly, as the hand of a watch runs round the points of the dial. The most exact anatomy of a plant does not unfold to us any organ which has the least relation to those of animal sensibility. When we oppose these observations to those from which we might infer the sensibility of plants, we remain in uncertainty, and we cannot explain the phenomena related above. Our knowledge upon this subject is very imperfect, and is confined to simple conjecture. We neither attribute sensibility to plants, nor deny it to them, with certainty.

THE SENSITIVE PLANT.--This singular plant rises from a slender woody stalk seven or eight feet in height, armed with short recurved thorns; the leaves grow upon long footstalks, which are p.r.i.c.kly, each sustaining two pair of wings; from the place where these are inserted, come out small branches, having three or four globular heads of pale purplish flowers coming out from the side, on short peduncles; the princ.i.p.al stalk has many of those heads of flowers on the upper part, for more than a foot in length; this, as also the branches, is terminated by like heads of flowers; the leaves move but slowly when touched, but the footstalks fall, when they are pressed pretty hard. It is a native of Brazil, (_M. pudica_, humble plant,) having the roots composed of many hairy fibres, which mat slowly together; from these come out several woody stalks, declining towards the ground, unless supported; they are armed with short recurved spines, having winged or pinnate leaves; flowers from the axils, on short peduncles, collected in small globular heads, of a yellow colour.

"Naturalists (says Dr. Darwin) have not explained the immediate cause of the collapsing of the sensitive plant; the leaves meet and close in the night, during the sleep of the plant, or when exposed to much cold in the day-time, in the same manner as when they are affected by external violence, folding their upper surfaces together, and in part over each other like scales or tiles, so as to expose as little of the upper surface as may be to the air, but do not, indeed, collapse quite so far; for when touched in the night during their sleep, they fall still further, especially when touched on the footstalks between the stems and the leaflets, which seem to be their most sensitive or irritable part. Now, as their situation after being exposed to external violence resembles their sleep, but with a greater degree of collapsion, may it not be owing to a numbness or paralysis consequent to too violent irritation, like the pantings of animals from pain or fatigue? A sensitive plant being kept in a dark room till some hours after day-break, its leaves and leaf-stalks were collapsed as in its most profound sleep, and on exposing it to the light, above twenty minutes pa.s.sed before the plant was thoroughly awake, and had quite expanded itself. During this night the upper surfaces of the leaves were oppressed; this would seem to shew that the office of this surface of the leaf was to expose the fluids of the plant to the light, as well as to the air." Dr. Darwin has thus characterized these plants.--

Weak with nice sense the chaste Mimosa stands, From each rude touch withdraws her timid hands Oft as light clouds o'erpa.s.s the summer glade, Alarm'd, she trembles at the moving shade; And feels alive through all her tender form, The whisper'd murmurs of the gathering storm; Shuts her sweet eyelids to approaching night, And hails with freshen'd charms the rising light.

THE COCOA-NUT TREE.

Of all the gifts which Providence has bestowed on the Oriental world, the cocoa-nut tree most deserves our notice: in this single production of nature, what blessings are conveyed to man! It grows a stately column, from thirty to fifty feet in height, crowned by a verdant capital of waving branches, covered with long spiral leaves; under this foliage, branches of blossoms, cl.u.s.ters of green fruit, and others arrived at maturity, appear in mingled beauty. The trunk, though porous, furnishes beams and rafters for our habitations; and the leaves, when platted together, make an excellent thatch, common umbrellas, coa.r.s.e mats for the floor, and brooms; while their finest fibres are woven into very beautiful mats for the rich. The covering of the young fruit is extremely curious, resembling a piece of thick cloth, in a conical form, close and firm as it came from the loom; it expands after the fruit has burst through its inclosure, and then appears of a coa.r.s.er texture. The nuts contain a delicious milk, and a kernel sweet as the almond: this, when dried, affords abundance of oil; and when that is expressed, the remains feed cattle and poultry, and make good manure. The sh.e.l.l of the nut furnishes cups, ladles, and other domestic utensils, while the husk which incloses it is of the utmost importance; it is manufactured into ropes and cordage of every kind, from the smallest twine to the largest cable, which are far more durable than those of hemp. In the Nicobar islands, the natives build their vessels, make the sails and cordage, supply them with provisions and necessaries, and provide a cargo of arrack, vinegar, oil, gagpree or coa.r.s.e sugar, cocoa-nuts, coir, cordage, black paint, and several inferior articles, for foreign markets, entirely from this tree.

Many of the trees are not permitted to bear fruit; but the embryo bud, from which the blossoms and nuts would spring, is tied up, to prevent its expansion; and a small incision being then made at the end, there oozes in gentle drops a cool pleasant liquor, called Trace, or Toddy, the palm wine of the poets. This, when first drawn, is cooling and salutary; but when fermented and distilled, produces an intoxicating spirit. Thus, a plantation of cocoa-nut trees yields the proprietor considerable profits, and generally forms part of the government revenue.

THE BREAD-FRUIT TREE.--The systematic name of this plant is Artocarpus, which is merely the English name translated into Greek. There are several species; particularly _A. incisa_, and _A. integrifolia_.

The genuine bread-fruit tree is the _artocarpus incisa_. In captain Cook's Voyage, it is observed, that the bread-fruit tree is about the size of a middling oak; its leaves are frequently a foot and a half long, oblong, deeply sinuated, like those of the fig-tree, which they resemble in consistence and colour, and in exuding a milky juice when broken. The fruit is the size and shape of a child's head, and the surface is reticulated, not much unlike a truffle; it is covered with a thin skin, and has a core about as big as the handle of a small knife; the eatable part lies between the skin and core; it is as white as snow, and of the consistence of new bread. It must be roasted before it is eaten, being first divided into three or four parts; its taste is insipid, with a slight sweetness, somewhat resembling that of the crumb of wheaten bread, mixed with Jerusalem artichoke. The fruit not being in season all the year, there is a method of supplying this defect, by reducing it to sour paste, called _makie_; and besides this, cocoa-nuts, bananas, plantains, and a great variety of other fruits, come in aid of it. This tree not only supplies food, but also clothing, for the bark is stripped off the suckers, and formed into a kind of cloth. To procure the fruit for food costs the Otaheiteans no trouble or labour, but climbing a tree. This most useful tree is distributed very extensively over the East Indian continent and islands, as well as the innumerable islands of the South Seas. In Otaheite, however, and some others, the evident superiority of the seedless variety for food has caused the other to be neglected, and it is consequently almost worn out.

We are informed by Captain King, that in the Sandwich islands these trees are planted, and flourish with great luxuriance on rising grounds; that they are not indeed in such abundance, but that they produce double the quant.i.ty of fruit to those growing on the rich plains of Otaheite; that the trees are nearly of the same height, but that the branches begin to strike out from the trunk much lower, and with greater luxuriance; and that the climate of these islands differs very little from that of the West Indian islands which lie in the same lat.i.tude. This reflection probably first suggested the idea of conveying this valuable tree to our islands in the West Indies. For this purpose his Majesty's ship the Bounty sailed for the South Seas, on the 23d of December, 1787, under the command of Lieutenant William Bligh. But a fatal mutiny prevented the accomplishment of this benevolent design. His Majesty, however, not discouraged by the unfortunate event of the voyage, and fully impressed with the importance of securing so useful an article of food as the bread-fruit to our West Indian Islands, determined, in the year 1791, to employ another ship, for a second expedition on this service; and, in order to secure the success of the voyage as much as possible, it was thought proper that two vessels should proceed together on this important business. Accordingly, a ship of 400 tons, named the Providence, was engaged for the purpose, and the command of her given to Captain Bligh; and a small tender, called the a.s.sistant, commanded by Lieut. Nathaniel Portlock. Sir Joseph Banks, as in the former voyage, directed the equipment of the ship for this particular purpose. Two skilful gardeners were appointed to superintend the trees and plants, from their transplantation at Otaheite, to their delivery at Jamaica; and Captain Bligh set sail on the 2d of August, 1791. The number of plants taken on board at Otaheite, was 2634, in 1281 pots, tubs, and cases; and of these 1151 were bread-fruit trees. When they arrived at Coupang, 200 plants were dead, but the rest were in good order. Here they procured ninety-two pots of the fruits of that country. They arrived at St. Helena, with 830 fine bread-fruit trees, besides other plants. Here they left some of them, with different fruits of Otaheite and Timor, besides mountain rice and other seeds; and hence the East Indies may be supplied with them.

On their arrival at St. Vincent's, they had 551 cases, containing 678 bread-fruit trees, besides a great number of other fruits and plants, to the number of 1245. Near half this cargo was deposited here under the care of Mr. Alexander Anderson, the superintendant of his Majesty's botanic garden, for the use of the Windward islands; and the remainder, intended for the Leeward islands, was conveyed to Jamaica, and distributed as the governor and council of Jamaica were pleased to direct. The exact number of bread-fruit trees brought to Jamaica, was 352; out of which, five only were reserved for the botanic garden at Kew. Captain Bligh had the satisfaction, before he quitted Jamaica, of seeing the trees, which he had brought with so much success, in a most flourishing state; insomuch that no doubt remained of their growing well, and speedily producing fruit: an opinion which subsequent reports have confirmed.

The bread-fruit, when perfectly ripe, is pulpy, sweetish, putrescent, and in this state is thought to be too laxative; but when green it is farinaceous, and esteemed a very wholesome food, either baked under the coals, or roasted over them. The taste is not unlike that of wheaten bread, but with some resemblance to that of Jerusalem artichokes or potatoes. It was mentioned before, that a sort of cloth was made of the inner bark: to this we may add, that the wood is used in building boats and houses; the male catkins serve for tinder; the leaves for wrapping their food in, and for wiping their hands instead of towels; and the juice for making bird-lime, and as a cement for filling up the cracks of their vessels, and for holding water. Three trees are supposed to yield sufficient nourishment for one person.

THE BANNIAN TREE.--The bannian, or Indian fig-tree, is a native of several parts of the East Indies, and has a woody stem, branching to a great height and vast extent. It is universally considered as one of the most beautiful of nature's productions; and, contrary to most other things in animal and vegetable nature, appears exempted from decay. Every branch from the main body throws out its own roots, at first in small tender fibres, several yards from the ground, but which thicken considerably before they reach the surface, and then, striking in, they increase to large trunks, and become parent trees, shooting out new branches from the top; these in time suspend their roots, which, swelling into trunks, produce other branches, thus continuing in a progressive state as long as the earth, the common parent of them all, continues her sustenance. The Hindoos are peculiarly fond of the bannian tree; they regard it as an emblem of the Deity, from its long duration and overshadowing beneficence, and almost pay it divine honours. Near this tree their most esteemed paG.o.das are generally erected; and under their shade the Brahmins spend their days in religious solitude, wandering among the cool recesses and beautiful walks of this umbrageous canopy, impervious to the hottest beams of a tropical sun.

A remarkably fine tree of this kind grows on an island in the river Narbedda, in the province of Guzerat. It is distinguished from others of the same species by the name of Cubbeer Bur, which was given it in honour of a famous saint. It was once much larger than it is at present, high and violent floods having carried away the banks of the island on which it grew, and with them such parts of the tree as have thus far extended its roots. What remains, is two thousand feet in circ.u.mference, measured round the princ.i.p.al stems; the overhanging branches, which have not yet struck down, cover a much larger s.p.a.ce. The chief trunks of this single tree, each of which in size exceeds our English oaks or elms, amount to 350, the smaller stems to more than 3000, all casting out new branches and hanging roots, to form in time parent trunks. Cubbeer Bur is famed through India for its amazing extent and beauty. The Indian armies frequently encamp around it, and at stated periods solemn festivals are held under its branches, where thousands of votaries repair from various parts of the empire. It is even said that 7000 persons found ample room under its shade. The English gentlemen sometimes form elegant and extensive encampments, where they spend whole weeks together under this delightful pavilion, which is inhabited by green wood-pigeons, doves, and peac.o.c.ks, and also a variety of feathered songsters; families of monkeys are also in every quarter playing their antic tricks; and bats, to the astonishing size of six feet, from the extremity of one wing to that of the other.

This tree not only shelters, but affords sustenance to these numerous inhabitants, being covered, amidst its bright leaves, with small figs of a rich scarlet, on which they regale.

FOUNTAIN TREES.--These are very extraordinary vegetables, growing in one of the Canary Islands, and likewise said to exist in some other places, which distil water from their leaves in such plenty, as to answer all the purposes of the inhabitants who live near them. Of these trees we have the following account, in Gla.s.se's History of the Canary Islands. "There are three fountains of water in the whole island of Hiero, wherein the fountain tree grows. The larger cattle are watered at those fountains, and at a place where water distils from the leaves of a tree. Many writers have made mention of this famous tree, some in such a manner as to make it appear miraculous: others again deny the existence of any such tree; among whom is Father Feyjoo, a modern Spanish author. But he, and those who agree with him in this matter, are as much mistaken as those who would make it appear to be miraculous. The author of the History of the Discovery and Conquest, has given us a particular account of it, which I shall here relate at large.--

"The district in which this tree stands is called Tigulabe; near to which, and in the cliff or steep rocky ascent that surrounds the whole island, is a gutter or gully, which commences at the sea, and continues to the summit of the cliff, where it joins or coincides with a valley, which is terminated by the steep front of a rock. On the top of this rock grows a tree, called, in the language of the ancient inhabitants, _ga.r.s.e_, sacred or holy tree, which for many years has been preserved sound, entire, and fresh. Its leaves constantly distil such a quant.i.ty of water as is sufficient to furnish drink to every living creature in Hiero, nature having provided this remedy for the drought of the island. It is situated about a league and a half from the sea. n.o.body knows of what species it is, only that it is called _til_. It is distinct from other trees, and stands by itself. The circ.u.mference of the trunk is about twelve spans, the diameter four, and in height, from the ground to the top of the highest branch, forty spans: the circ.u.mference of all the branches together is 120 feet. The branches are thick and extended, the lowest commence about the height of an ell from the ground. Its fruit resembles the acorn, and tastes something like the kernel of a pine-apple, but is softer and more aromatic. The leaves of this tree resemble those of the laurel, but are larger, wider, and more curved; they come forth in a perpetual succession, so that the tree always remains green. Near to it grows a thorn, which fastens on many of its branches, and interweaves with them; and at a small distance from the ga.r.s.e are some beech-trees, bresoes, and thorns. On the north side of the trunk are two large tanks or cisterns, of rough stone, or rather one cistern divided, each half being twenty feet square, and sixteen spans in depth. One of these contains water for the drinking of the inhabitants; and the other, that which they use for their cattle, washing, and such like purposes.

"Every morning, near this part of the island, a cloud or mist arises from the sea, which the south or easterly winds force against the forementioned steep cliff; so that the cloud, having no vent but by the gutter, gradually ascends it, and from thence advances slowly to the extremity of the valley, where it is stopped and checked by the front of the rock which terminates the valley; and then rests upon the thick leaves and wide spreading branches of the tree, from whence it distils in drops during the remainder of the day, until it is at length exhausted, in the same manner that we see water drip from the leaves of trees after a heavy shower of rain.

"This distillation is not peculiar to the ga.r.s.e or til, for the bresoes, which grow near it, likewise drop water; but their leaves being but few and narrow, the quant.i.ty is so trifling, that, though the natives save some of it, yet they make little or no account of any but what distils from the til; which, together with the water of some fountains, and what is saved in the winter season, is sufficient to serve them and their flocks. A person lives on the spot near which this tree grows, to take care of it and its waters; and is allowed a house to live in, with a certain salary. He every day distributes to each family of the district, seven pots or vessels full of water, besides what he gives to the princ.i.p.al people of the island."

Whether the tree which yields water at this present time, be the same as that mentioned in the above description, I cannot determine: but it is probable there has been a succession of them; for Pliny, describing the Fortunate Island, says, "In the mountains of Ombrion, are trees resembling the plant _ferula_, from which water may be procured by pressure. What comes from the black kind is bitter, but that which the white yields is sweet and potable." Trees yielding water are not peculiar to the island of Hiero; for travellers inform us of one of the same kind on the island of St. Thomas, in the bight or gulf of Guinea. In c.o.c.kburn's Voyages, we find the following account of a dropping tree, near the mountains of Fera Paz, in America.--

"On the morning of the fourth day, we came out on a large plain, where were great numbers of fine deer; and in the middle stood a tree of unusual size, spreading its branches over a vast compa.s.s of ground. Curiosity led us up to it. We had perceived, at some distance, the ground about it to be wet; at which we began to be somewhat surprised, as well knowing there had no rain fallen for nearly six months past, according to the certain course of the season in that lat.i.tude: that it was impossible to be occasioned by the fall of dew on the tree, we were convinced, by the sun's having power to exhale away all moisture of that nature a few minutes after its rising.

At last, to our great amazement, as well as joy, we saw water dropping, or as it were distilling, fast from the end of every leaf of this wonderful, (nor had it been amiss if I had said miraculous) tree; at least it was so with respect to us, who had been labouring four days through extreme heat, without receiving the least moisture, and were now almost expiring for the want of it. We could not help looking on this as liquor sent from heaven, to comfort us under great extremity. We catched what we could of it in our hands, and drank very plentifully of it; and liked it so well, that we could hardly prevail with ourselves to give over. A matter of this nature could not but incite us to make the strictest observations concerning it; and accordingly we staid under the tree near three hours, and found we could not fathom its body in five times. We observed the soil where it grew to be very strong; and upon the nicest inquiry we could afterwards make, both of the natives of the country and the Spanish inhabitants, we could not learn there was any such tree known throughout New Spain, nor perhaps all America over: but I do not relate this as a prodigy in nature, because I am not philosopher enough to ascribe any natural cause for it; the learned may perhaps give substantial reasons in nature, for what appeared to us a great and marvellous secret, and far beyond our power to account for."

THE TALLOW TREE.--This is a remarkable tree, growing in great plenty in China; so called from its producing a substance like tallow, and which serves for the same purpose: it is about the height of a cherry-tree, its leaves in form of a heart, of a deep shining red colour, and its bark very smooth. Its fruit is inclosed in a kind of pod, or cover, like a chesnut, and consists of three round white grains, of the size and form of a small nut, each having its peculiar capsule, and a little stone within. This stone is encompa.s.sed with a white pulp, which has all the properties of true tallow, both as to consistence, colour, and even smell, and accordingly the Chinese make their candles of it; which would doubtless be as good as those in Europe, if they knew how to purify their vegetable, as well as we do our animal tallow. All the preparation they give it, is to melt it down, and mix a little oil with it, to make it softer and more pliant. It is true, the candles made of it yield a thicker smoke and a dimmer light than ours; but those defects are owing in a great measure to the wicks, which are not of cotton, but only a little rod of dry light wood, covered with the pith of a rush wound round it; which, being very porous, serves to filtrate the minute parts of the tallow, attracted by the burning stick, and by this means is kept alive.

THE PAPER TREE.--The name of this tree is _Aouta_. It is a mulberry-tree, found at Otaheite, in the South Sea, from which a cloth is manufactured, that is worn by the princ.i.p.al inhabitants. The bark of the trees is stripped off, and deposited to soak in running water; when it is sufficiently softened, the fibres of the inner coat are carefully separated from the rest of the bark; they are then placed in lengths of about eleven or twelve yards, one by the side of another, till they are about a foot broad; and two or three layers are put one upon another. This is done in the evening; and next morning the water is drained off, and the several fibres adhere together in one piece. It is afterwards beaten on a smooth piece of wood with instruments marked lengthways, with small grooves of different degrees of fineness; and by means of this it becomes as thin as muslin. After bleaching it in the air, to whiten it, it is fit for use.

Another article worthy of the reader's attention, is the ADANSONIA, ETHIOPIAN SOUR GOURD, MONKEYS' BREAD, or AFRICAN CALABASH TREE.--There is but one known species belonging to this genus, the _baobal_, which is perhaps the largest production of the whole vegetable kingdom. It is a native of Africa. The trunk is not above twelve or fifteen feet high, but from sixty to seventy feet round. The lowest branches extend almost horizontally, and as they are about sixty feet in length, their own weight bends their extremities to the ground, and thus form an hemispherical ma.s.s of verdure of about 120 or 130 feet diameter. The roots extend as far as the branches: that in the middle forms a pivot, which penetrates a great way into the earth; the rest spread near the surface. The flowers are in proportion to the size of the tree, and are followed by an oblong pointed fruit, ten inches long, five or six broad, and covered with a kind of greenish down, under which is a ligneous rind, hard, and almost black, marked with rays, which divide it lengthwise into sides. It is very common in Senegal, and the Cape de Verd islands; and is found 100 leagues up the country, at Gulam, and upon the sea-coast as far as Sierra Leone.

The age of this tree is no less remarkable than its enormous size. Mr.

Adanson relates, that, in a botanical excursion to the Magdalen Islands, he discovered some calabash-trees, from five to six feet diameter, on the bark of which were engraved, or cut to a considerable depth, a number of European names. Two of these names, which he was at the trouble to repair, were dated, one in the fourteenth, the other in the fifteenth century. The inscribed trees, mentioned by this ingenious Frenchman, had been seen in 1555, almost two centuries before, by Thevet, who mentions them in his relation of his Voyage to Terra Antarctia, or Australis. Adanson saw them in 1749. The virtues and uses of this tree and its fruits are various. The negroes of Senegal dry the bark and leaves in the shaded air, and then reduce them to powder, which is of a pretty good green colour. This powder they preserve in bags of linen or cotton, and call it _lillo_. They use it every day, putting three or four pinches of it into a mess, whatever it happens to be, as we do pepper and salt: but their view is, not to give a relish to their food, but to preserve a perpetual and plentiful perspiration, and to attemper the too great heat of the blood; purposes to which it certainly answers, as several Europeans have proved by repeated experiments; preserving themselves from the epidemic fever, which, in that country, is as fatal to them as the plague, and generally rages during the months of September and October: when the rains have suddenly ceased, the sun exhales the water left by them on the ground, and fills the air with a noxious vapour. M. Adanson, in the critical season, made a light ptisan of the leaves of the baobal; which he had gathered in the August of the preceding year, and had dried in the shade; and drank constantly about a pint of it every morning, either before or after breakfast, and the same quant.i.ty of it every evening, after the heat of the sun began to abate: he also took the same quant.i.ty in the middle of the day, but this was only when he felt some symptoms of an approaching fever. By this precaution he preserved himself, during the five years he resided at Senegal, from the diarrhaea and fever, which are so fatal there, and which are, however, the only diseases of the place; while other officers suffered very severely, only one of them excepted, upon whom M. Adanson prevailed to use this remedy, which for its simplicity was despised by the rest. This ptisan alone prevents that heat of urine which is common in these parts, from the month of July to November, provided the person abstains from wine. The fruit is not less useful than the leaves and the bark. The pulp that envelopes the seeds has an agreeable acid taste, and is eaten for pleasure: it is also dried and powdered, and used medicinally in pestilential fevers, the dysentery, and b.l.o.o.d.y flux: the dose is a drachm, pa.s.sed through a fine sieve, taken either in common water, or in an infusion of the plantain. This powder is brought into Europe under the name of _terra sigillata Lemnia_. The woody bark of the fruit, and the fruit itself, when spoiled, help to supply the negroes with an excellent soap, which they make by drawing a lie from the ashes, and boiling it with palm-oil that begins to be rancid. The trunks of such of these trees as are decayed, the negroes hollow out into burying places for their poets, musicians, and buffoons. Persons of these characters they esteem greatly while they live, supposing them to derive their superior talents from sorcery, or a commerce with demons; but they regard their bodies with horror when dead, and will not give them burial in the usual manner, neither suffering them to be put into the ground, nor thrown into the sea or any river, because they imagine that the water would not then nourish the fish, nor the earth produce its fruits. The bodies shut up in these trunks become dry without rotting, and form a kind of mummies without the help of embalming. The baobal is very distinct from the calabash-tree of America, with which it has been confounded by Father Labat.

The following is an account of a REMARKABLE OAK TREE:--

Behold the oak does young and verdant stand Above the grove, all others to command; His wide-extended limbs the forest crown'd, Shading the trees, as well as they the ground: Young murm'ring tempests in his boughs are bred, And gathering clouds from round his lofty head; Outrageous thunder, stormy winds, and rain, Discharge their fury on his head in vain; Earthquakes below, and lightnings from above, Rend not his trunk, nor his fix'd root remove.

_Blackmore._

Mr. Gilpin, in his forest scenery, gives the following account of an aged oak:--

"Close by the gate of the Water-walk, at Magdalen College in Oxford, grew an oak, which perhaps stood there a saplin when Alfred the Great founded the university. This period only includes a s.p.a.ce of nine hundred years, which is no great age for an oak. It is a difficult matter indeed to ascertain the age of a tree. The age of a castle or abbey is the object of history: even a common house is recorded by the family that built it. All these objects arrive at maturity in their youth, if I may so speak. But the tree gradually completing its growth, is not worth recording in the early part of its existence: it is then only a common tree; and afterwards, when it becomes remarkable for its age, all memory of its youth is lost. This tree, however, can almost produce historical evidence for the age a.s.signed to it."

About five hundred years after the time of Alfred, William of Wainfleet, Dr. Stukely tells us, expressly ordered this college to be founded near the great oak; (_Itiner. Curios._) and an oak could not, I think, be less than five hundred years of age, to merit that t.i.tle, together with the honour of fixing the site of a college. When the magnificence of Cardinal Wolsey erected that handsome tower which is so ornamental to the whole building, this tree might probably be in the meridian of its glory; or rather, perhaps it had attained a green old age. But it must have been manifestly in its decline, at that memorable aera, when the tyranny of James gave the fellows of Magdalen so n.o.ble an opportunity of withstanding bigotry and superst.i.tion. It was afterwards much injured in the time of Charles II, when the present walks were laid out: its roots were disturbed; and from that period it declined fast, and became reduced by degrees to little more than a mere trunk. The oldest members of the university can scarcely recollect it in better plight: but the faithful records of history[20] have handed down its ancient dimensions.

It once flung its boughs through a s.p.a.ce of sixteen yards on every side from its trunk; and under its magnificent pavilion could have sheltered with ease three thousand men: though in its decayed state, it could, for many years, do little more than shelter some luckless individual, whom the driving shower had overtaken in his evening walk. In the summer of the year 1788, this magnificent ruin fell to the ground, alarming the college with its crashing sound. It then appeared how precariously it had stood for many years. Its grand taproot was decayed; and it had hold of the earth only by two or three roots, of which none was more than a couple of inches in diameter. From a part of its ruins, a chair has been made for the president of the college, which will long continue its memory.

This will be a proper place for introducing the history of SOME OF THE LARGEST TREES NOW GROWING IN ENGLAND.--In Hainault Forest, near Barking in Ess.e.x, there is an oak which has attained the enormous bulk of thirty-six feet in circ.u.mference. This extraordinary tree has been known for ages by the name of Fairlop. The tradition of the country traces it half way up the Christian aera. Beneath its shade, which overspreads an area of three hundred feet in circuit, an annual fair has long been held on the first Friday in July, and no booth is suffered to be erected beyond the extent of its boughs.

At Cromwell Park, near Letbury in Gloucestershire, the seat of Lord Dacre, is a huge chesnut tree, probably as remarkable for antiquity as size; having been mentioned (according to Sir Richard Atkins) in king John's days, six centuries ago, as the wonder of the neighbourhood, and measuring at present, at the foot, fifty-seven feet in circ.u.mference. It is supposed to be at least eight hundred years old.

In Darley church-yard, near Matlock in Derbyshire, is a yew tree, thirty-three feet in girt.
