[THE BOTANIC GARDEN. PART II. THE LOVES OF THE PLANTS.]
THE LOVES OF THE PLANTS.
CANTO I.
Vegetable Loves. l. 10. Linneus, the celebrated Swedish naturalist, has demonstrated, that all flowers contain families of males or females, or both; and on their marriages has constructed his invaluable system of Botany.
Canna. l. 39. Cane, or Indian Reed. One male and one female inhabit each flower. It is brought from between the tropics to our hot-houses, and bears a beautiful crimson flower; the seeds are used as shot by the Indians, and are strung for prayer-beads in some catholic countries.
Callitriche. l. 45. Fine-Hair, Stargrass. One male and two females inhabit each flower The upper leaves grow in form of a star, whence it is called Stellaria Aquatica by Ray and others; its stems and leaves flo•t far on the water, and are often so matted together, as to bear a person walking on them. The male sometimes lives in a separate flower.
Collinsonia. l. 51. Two males one female. I have lately observed a very singular cir cumstance in this flower; the two males stand widely diverging from each other, and the female bends herself into contact first with one of them, and after some time leaves this, and applies herself to the other. It is probable one of the anthers may be mature before the other? See note on Gloriosa, and Genista. The females in Nigella, devil in the bush, are very tall compared to the males; and bending over in a circle to them, give the flower some resemblance to a regal crown. The female of the epilobium angustifolium, rose bay willow herb, bends down amongst the males for several days, and becomes up right again when impregnated.
Genista. l. 57. Dyer's broom. Ten males and one female inhabit this flower. The males are generally united at the bottom in two sets, whence Linneus has named the class "two brotherhoods." In the Genista, however, they are united in but one set. The flowers of this class are called papilionaccous, from their resemblance to a butterfly, as the pea-blossom. In the Spartium Scoparium, or common broom, I have lately observed a curious circumstance, the males or stamens are in two sets, one set rising a quarter of an inch above the other; the upper set does not arrive at their maturity so soon as the lower, and the stigma, or head of the female, is produced amongst the upper or immature set; but as soon as the pistil grows tall enough to burst open the keel-leaf, or hood of the flower, it bends itself round in an instant, like a French horn, and inserts its head, or stigma, amongst the lower or mature set of males. The pistil, or female, continues to grow in length; and in a few days the stigma arrives again amongst the upper set, by the time they become mature. This wonderful contrivance is readily seen by opening the keel-leaf of the flowers of broom before they burst spontaneously. See note on Collinsonia, Gloriosa, Draba.
Melissa l. 60. Balm. In each flower there are four males and one female; two of the males stand higher than the other two; whence the name of the class "two powers." I have observed in the Ballota, and others of this class, that the two lower stamens, or makes become mature before the two higher. After they have shed their dust, they turn themselves away outwards; and the pistil, or female, continuing to grow a little taller, is applied to the upper stamens. See Glorista, and Genista.
All the plants of this class, which have naked seeds, are aromatic. The Marum, and Nepeta are particularly delightful to cats; no other brute animals seem pleased with any odours but those of their food or prey.
Meadia. l. 61. Dodecatheon, American Cowslip. Five males and one female. The males, or anthers, touch each other. The uncommon beauty of this flower occasioned Linneus to give it a name signifying the twelve heathen gods; and Dr. Mead to affix his own name to it. The pistil is much longer than the stamens, hence the flower-stalks have their elegant bend, that the stigma may hang downwards to receive the fecundating dust of the anthers. And the petals are so beautifully turned back to prevent the rain or dew drops from sliding down and washing off this dust prematurely; and at the same time exposing it to the light and air. As soon as the seeds are sormed, it erects all the flower - stalks to prevent them from salling out; and thus loses the beauty of its figure. Is this a mechanical effect, or does it indicate a vegetable storgé to preserve its offspring? See note on Ilex, and Gloriosa.
In the Meadia, the Borago, Cyclamen, Solanum, and many others, the filaments are very short compared with the style. Hence it became necessary, 1st, to furnish the stamens with long anthers. 2d. I'o lengthen and bend the peduncle or flower-stalk, that the flower might hang downwards. 3d. To reflect the petals. 4th. To erect these pe duncles when the germ was fecundated. We may reason upon this by observing, that all this apparatus might have been spared, if the filaments alone had grown longer; and that thence in these flowers that the filaments are the most unchangeable parts; and that thence their comparative length, in respect to the style, would afford a most permanent mark of their generic character.
Curcuma. l. 65. Turmeric. One male and one female inhabit this flower; but there are besides four imperfect males, or filaments without anthers upon them, called by Lin neus eunuchs. The flax of our country has ten filaments, and but five of them are ter minated with anthers; the Portugal flax has ten perfect males, or females; the Verbena of our country has four males; that of Sweden has but two; the genus Albuca, the Bignonia Catalpa, Gratiola, and hemlock-leaved Geranium have only half their filaments crowned with anthers. In like manner the florets, which form the rays of the flowers of the order frustraneous polygamy of the class syngenesia, or confederate males, as the sun flower, are furnished with a style only, and no stigma: and are thence barren. There is also a style without a stigma in the whole order dioecia gynandria; the male flowers of which are thence barren. The Opulus is another plant, which contains some unpro lific flowers. In like manner some tribes of insects have males, females, and neuters among them: as bees, wasps, ants.
There is a curious circumstance belonging to the class of insects which have two wings, or diptera, analogous to the rudiments of stamens above described; viz. two little knobs are found placed each on a stalk or peduncle, generally under a little arched scale; which appear to be rudiments of hinder wings; and are called by Linneus, halteres, or poisers, a term of his introduction. A. T. Bladh. Amaen. Acad. V. 7. Other animals have marks of having in a long process of time undergone changes in some parts of their bodies, which may have been effected to accommodate them to new ways of procuring their food. The existence of teats on the breasts of male animals, and which are gene rally rep'ete with a thin kind of milk at their nativity, is a wonderful instance of this kind. Perhaps all the productions of nature are in their progress to greater perfection? an idea countenanced by the modern discoveries and deductions concerning the progres sive formation of the solid parts of the terraqueous globe, and consonant to the dignity of the Creator of all things.
Alcea. l. 69. Flore pleno. Double hollyhock. The double flowers, so much ad mired by the florists, are termed by the botanist vegetable monsters; in some of these the petals are multiplied three or four times, but without excluding the stamens, hence they produce some seeds, as Campanula and Stramoneum; but in others the petals become so numerous as totally to exclude the stamens, or males; as Caltha, Peonia, and Alcea; these produce no seeds, and are termed eunuchs. Philos. Botan. No. 150.
These vegetable monsters are formed in many ways. 1st. By the multiplication of the petals and the exclusion of the nectaries, as in larkspur. 2d. By the multiplication of the nectaries and exclusion of the petals; as in columbine. 3d. In some flowers grow ing in cymes, the wheel-shape flowers in the margin are multiplied to the exclusion of the bell-shape flowers in the centre; as in gelder-rose. 4th. By the elongation of the florets in the centre. Instances of both these are found in daily feverfew; for other kinds of vegetable monsters, see Plantago.
The per•anth is not changed in double flowers, hence the genus or family may be often disovered by the calyx, as in Hepatica, Ranunculus, Alcea. In those flowers, which have many petals, the lowest series of the petals remains unchanged in respect to num ber; hence the natural number of the petals is easily discovered. As in poppies, roses, and Nigella, or devil in a bush. Phil. Bot. p. 128.
Iris. 1. 71. Flower de Luce. Three males, one female. Some of the species have a beautifully freckled flower; the large stigma or head of the female covers the three males, counterfeiting a petal with its divisions.
Cupressus. l. 73. Cypress. One Hosse. The males live in separate flowers, but on the same plant. The males of some of these plants, which are in separate flowers from the females, have an elastic membrane; which disperses their dust to a considerable dis tance, when the anthers burst open. This dust, on a fine day, may often be seen like a cloud hanging round the common nettle. The males and females of all the cone bearing plants are in separate flowers, either on the same or on different plants; they produce resins, and many of them are supposed to supply the most durable timber: what is called Venice-turpentine is obtained from the larch by wounding the bark about two feet from the ground, and catching it as it exsudes; Sanda•ach is procured from com mon juniper; and lncense from a juniper with yellow fruit. The unperishable chests, which contain the Egyptian mummies, were of Cypress; and the Cedar, with which black lead pencils are covered, is not liable to be eaten by worms. See Miln's Bot. Dict. art. coniferae. The gates of St. Peter's church at Rome, which had lasted from the time of Constantine to that of Pope Eugene the fourth, that is to say eleven hun dred years, were of Cypress, and had in that time suffered no decay. According to Thucydides, the Athenians buried the bodies of their heroes in coffins of Cypress, as being not subject to decay. A similar durability has also been ascribed to Cedar. Thus Horace,
Osyris. l. 75. Two houses. The males and females are on different plants. There are many instances on record, where female plants have been impregnated at very great distance from their male; the dust discharged from the anthers is very light, small, and copious, so that it may spread very wide in the atmosphere, and be carried to the distant pistils, without the supposition of any particular attraction; these plants resemble some insects, as the ants, and cochineal insect, of which the males have wings, but not the female.
Plantago. l. 77. Rosea. Rose-Plantain. In this vegetable monster the bractes, or di visions of the spike, become wonderfully enlarged; and are converted into leaves. The chassy scales of the calyx in Xeranthemum, and in a species of Dianthus, and the glume in some alpine grasses, and the scales of the ament in the salix rosea willow, grow into leaves; and produce other kinds of monsters. The double flowers become monsters by the multiplication of their petals or nectaries. See note on Alcea.
Anthoxanthum. l. 83. Vernal grass. Two males, two females. The other grasses have three males and two females. The flowers of this grass give the fragrant scent to hay. I am informed it is frequently viviparous, that is, that it bears sometimes roots or bulbs inst ad of seeds, which after a time drop off and strike root into the ground. This circumstance is said to obtain in many of the alpine grasses, whose seeds are perpetually devoured by small birds. The Festuca Dumetorum, sescue grass of the bushes, produces bulbs from the sheaths of its straw. The Allium Magicum, or magical onion, produces onions on its head, instead of seeds. The Polygonum Viviparum, viviparous bistort, rises about a foot high, with a beautiful spike of flowers, which are succeeded by buds or bulbs, which fall off and take root. There is a bush frequently seen on birch-trees, like a bird's nest, which seems to be a similar attempt of nature, to produce another tree; which falling off might take root in spongy ground.
There is an instance of this double mode of production in the animal kingdom, which is equally extraordinary: the same species of Aphis is viviparous in summer, and ovi parous in autumn. A. T. Bladh. Amoen. Acad. V. 7.
Osmunda. l. 93. This plant grows on moist rocks; the parts of its flower or its seeds are scarce discernible; whence Linneus has given the name of clandestine marriage to this class. The younger plants are of a beautiful vivid green.
Chondrilla. l. 97. Of the class Confederate Males. The numerous florets, which constitu•e the disk of the flowers in this class, contain in each five males surrounding one female, which are connected at top, whence the name of the class. An Italian writer, in a discourse on the irritability of flowers, asserts, that if the top the floret be touched, all the filaments which support the cylindrical anther will contract themselves, and that by thus raising or depressing the anther the whole of the prolific dust is collected on the stigma. He adds, that if one filament be touched after it is separated from the floret, that it will contract like the muscular fibres of animal bodies, his experiments were tried on the Centauréa Calcitiapoides, and on artichokes, and globe-thistles. Dis course on irritability of plants. Dodsley.
Lychnis. l. 108. Ten males and five females. The flowers which contain the five females, and those which contain the ten males, are found on different plants; and often at a great distance from each other. Five of the ten males arrive at their maturity some days before the other five, as may be seen by opening the corol before it naturally expands itself. When the females arrive at their maturity, they rise above the petals, as if looking abroad for their distant husbands; the scarlet ones contribute much to the beauty of our meadows in May and June.
Gloriosa. l. 119. Superba. Six males, one female. The petals of this beautiful flower with three of the stamens, which are first mature, stand up in apparent disorder; and the pistil bends at nearly a right angle to insert its stigma amongst them. In a few days, as these decline, the other three stamens bend over, and approach the pistil. In the Fritillaria Persica, the six stamens are of equal lengths, and the anthers lie at a distance from the pistil, and three alternate ones approach first; and, when these decline, the other three approach; in the Lithrum Salicaria, (which has twelve males and one female) a beautiful red flower, which grows on the banks of rivers, six of the males arrive at ma turity, and surround the female some time before the other six; when these decline, the other six rise up, and supply their places. Several other flowers have in similar manner two sets of stamens of different ages, as Adoxa, Lychnis, Saxifraga. See Genista. Per haps a difference in the time of their maturity obtains in all these flowers, which have numerous stamens. In the Kalmia the ten stamens lie round the pistil like the radii of a wheel; and each anther is concealed in a nich of the corol to protect it from cold and moisture; these anthers rise separately from their niches, and approach the pistil for a time, and then recede to their former situations.
Silene. l. 139. Catchfly. Three females and ten males inhabit each flower; the viscous material, which surrounds the stalks under the flowers of this plant, and of the Cucubulus Otites, is a curious contrivance to prevent various insects from plundering the honey, or devouring the seed. In the Dionaea Muscipula there is a still more won derful contrivance to prevent the depredations of insects: The leaves are armed with long teeth, like the antennae of insects, and lie spread upon the ground round the stem; and are so irritable, that when an insect creeps upon them, they fold up, and crush or pierce it to death. The last professor Linneus, in his Supplementum Plantarum, gives the fol lowing account of the Arum Muscivorum. The flower has the smell of carrion; by which the flies are invited to lay their eggs in the chamber of the flower, but in vain en deavour to escape, being prevented by the hairs pointing inwards; and thus perish in the flower, whence its name of fly-eater. P. 411. in the Dypsacus is another contrivance for this purpose, a bason of water is placed round each joint of the stem. In the Drosera is another kind of fly-trap. See Dypsacus and Drosera; the flowers of Siléne and Cucú balus are closed all day, but are open and give an agreeable odour in the night. See Cerea. See additional notes at the end of the poem.
Amaryllis. l. 152. Formosissima. Most beautiful Amaryllis. Six males, one female. Some of the bell-flowers close their apertures at night, or in rainy or cold weather, as the convolvulus, and thus protect their included stamens and pistils. Other bell-flowers hang their apertures downwards, as many of the lilies; in those the pistil, when at maturity, is longer than the stamens; and by this pendant attitude of the bell, when the anthers burst, their dust falls on the stigma; and these are at the same time sheltered as with an umbrella from rain and dews. But, as a free exposure to the air is necessary for their fecundation, the style and filaments in many of these flowers continue to grow longer after the bell is open, and hang down below its rim. In others, as in the mar tagon, the bell is deeply divided, and the divisions are reflected upwards, that they may not prevent the access of air, and at the same time afford some shelter from perpendicular rain or dew. Other bell-flowers, as the hemerocallis and amaryllis, have their bells nodding only, as it were, or hanging obliquely toward the horizon; which, as their stems are slender, turn like a weathercock from the wind; and thus very effectually preserve their inclosed stamens and anthers from the rain and cold. Many of these flowers, both before and after their season of fecundation, erect their heads perpen dicular to the horizon, like the Meadia, which cannot be explained from meer mechanism.
The Amaryllis formosissima is a flower of the last mentioned kind, and affords an agreeable example of art in the vegetable economy. 1. The pistil is of great length compared with the stamens; and this I suppose to have been the most unchangeable part of the flower, as in Meadia, which see. 2. To counteract this circumstance, the pistil and stamens are made to decline downwards, that the prolific dust might fall from the anthers on the stigma. 3. To produce this effect, and to secure it when produced, the corol is lacerated, contrary to what occurs in other flowers of this genus, and the lowest division with the two next lowest ones are wrapped closely over the style and filaments, binding them forceibly down lower toward the horizon than the usual inclination of the bell in this genus, and thus constitutes a most elegant flower. There is another con trivance for this purpose in the Hemeroca•lis flava; the long pistil often is bent some what like the capital letter N, with design to shorten it, and thus to bring the stigma amongst the anthers.
Ilex. l. 161. Holly. Four males, four females. Many plants, like many animals, are furnished with arms for their protection; these are either aculei, prickles, as in rose and barberry, which are formed from the outer bark of the plant; or spinae, thorns, as in hawthorn, which are an elongation of the wood, and hence more difficult to be torn off than the former; or stimuli, stings, as in the nettles, which are armed with a venom ous fluid for the annoyance of naked animals. The shrubs and trees, which have prickles or thorns, are grateful food to many animals, as goosberry, and gorse; and would be quickly devoured, if not thus armed; the stings seem a protection against some kinds of insects, as well as the naked mouths of quadrupeds. Many plants lose their thorns by cultivation, as wild animals lose their ferocity; and some of them their horns. A curi ous circumstance attends the large hollies in Needwood-forest, they are armed with thorny leaves about eight feet high, and have smooth leaves above; as if they were con scious that horses and cattle could not reach their upper branches. See note on Meadia, and on Mancinella. The numerous clumps of hollies in Needwood-forest serve as land marks to direct the travellers across it in various directions; and as a shelter to the deer and cattle in winter; and in scarce seasons supply them with much food. For when the upper branches, which are without prickles, are cut down, the deer crop the leaves and peel off the bark. The bird-lime made from the bark of hollies seems to be a very similar material to the elastic gum, or Indian rubber, as it is called. There is a fossile elastic bitumen found at Matlock in Derbyshire, which much resembles these substances in its elasticity and inflammability. The thorns of the mimosa cornigere resemble cow's horns in appearance as well as in use. System of Vegetables, p. 782.
Hurls his red lavas. l. 176. Alluding to the grand paintings of the eruptions of Vesuvius, and of the destruction of the Spanish vessels before Gibraltar; and to the beautiful landscapes and moonlight scenes, by Mr. Wright of Derby.
Kleinhovia. l. 183. In this class the males in each flower are supported by the female. The name of the class may be translated "Viragoes," or "Feminine Males."
The largest tree perhaps in the world is of the same natural order as Kleinhovia, it is the Adansonia, or Ethiopian Sour-gourd, or African Calabash tree. Mr. Adanson says the diameter of the trunk frequently exceeds 25 feet, and the horizontal branches are from 45 to 55 feet long, and so large that each branch is equal to the largest trees of Europe. The breadth of the top is from 120 to 150 feet. And one of the roots bared only in part by the washing away of the earth by the river, near which it grew, mea sured 110 feet long; and yet these stupendous trees never exceed 70 feet in height. Voyage to Senegal.
Tulipa. l. 205. Tulip. What is in common language called a bulbous root, is by Linneus termed the Hybernacle, or Winter-lodge of the young plant. As these bulbs in every respect resemble buds, except in their being produced under ground, and in clude the leaves and flower in miniature, which are to be expanded in the ensuing spring. By cautiously cutting in the early spring through the concentric coats of a tulip-root, longitudinally from the top to the base, and taking them off successively, the whole flower of the next summer's tulip is beautifully seen by the naked eye, with its petals, pistil, and stamens; the flowers exist in other bulbs, in the same manner, as in Hya cinths, but the individual flowers of these being less, they are not so easily dissected, or so conspicuous to the naked eye.
In the seeds of the Nymphaea Nelumto, the leaves of the plant are seen so distinctly, that Mr. Ferber sound out by them to what plant the seeds belonged. Amoen. Acad. V. vi. No. 120. He says that Mariotte first observed the future flower and foliage in the bulb of a Tulip; and adds, that it is pleasant to see in the buds of the Hepatica, and Pedicularis hirsuta, yet lying in the earth; and in the gems of Daphne Mezoreon; and at the base of Osmunda Lunaria, a perfect plant of the future year compleat in all its parts. Ibid.
Colchicum autumnale. l. 214. Autumnal Meadow-sassion. Six males, three females. The germ is buried within the root, which thus seems to constitute a part of the flower. Families of Plants. p. 242. These singular flowers appear in the autumn without any leaves, whence in some countries they are called Naked Ladies: in the March following the green leaves spring up, and in April the feed-vessel rises from the ground; the seeds ripen in May, contrary to the usual habits of vegetables, which flower in the spring, and ripen their seeds in the autumn. Miller's Dict. The juice of the root of this plant is so acrid as to produce violent effects on the human constitution, which also prevents it from being eaten by subterranean infects, and thus guards the seed-vessel during the winter. The desoliation of deciduous trees is announced by the flowering of the Colchicum; of these the ash is the last that puts forth its leaves, and the first that loses them. Phil. Bot. p. 275.
The Hamamelis, Witch Hazle, is another plant which flowers in autumn; when the leaves fall off, the flowers come out in clusters from the joints of the branches, and in Virginia ripen their seed in the ensuing spring; but in this country their seeds seldom ripen. Lin. Spec. Plant. Miller's Dict.
Helianthus. l. 223. Sun flower. The numerous florets, which constitute the disk of this flower, contain in each five males surrounding one female, the five stamens have their anthers connected at top, whence the name of the class "confederate male;" see note on Chondrilla. The sun-flower follows the course of the sun by nutation, not by twisting its stem. (Hales veg. stat.) Other plants, when they are confined in a room, turn the shining surface of their leaves, and bend their whole branches to the light. See Mimosa.
A plumed Lady leads. l. 226. The seeds of many plants of this class are furnished with a plume, by which admirable mechanism they are disseminated by the winds far from their parent stem, and look like a shuttlecock, as they fly. Other seeds are disseminated by animals; of these some attach themselves to their hair or feathers by a gluten, as misleto; others by hooks, as cleavers, burdock, hounds-tongue; and others are swallowed whole for the sake of the fruit, and voided uninjured, as the hawthorn, juniper, and some grasses. Other seeds again disperse themselves by means of an elastic seed-vessel, as Oats, Geranium, and Impatiens; and the seeds of aquatic plants, and of those which grow on the banks of rivers, are carried many miles by the currents, into which they fall. See Impatiens. Zostera. Cassia. Carlina.
Drosera. l. 231. Sun-dew. Five males, five females. The leaves of this marsh plant are purple, and have a fringe very unlike other vegetable productions. And, which is curious, at the point of every thread of this erect fringe stands a pellucid drop of mu cilage, resembling a ducal coronet. This mucus is a secretion from certain glands, and like the viscous material round the flower-stalks of Silene (catchfly) prevents small in sects from infesting the leaves. As the ear-wax in animals seems to be in part designed to prevent fleas and other infects from getting into their ears. See Silene. Mr. Wheatly, an eminent surgeon in Cateaton-street, London, observed these leaves to bend upwards, when an insect settled on them, like the leaves of the muscipula veneris, and pointing all their globules of mucus to the centre, that they compleatly intangled and destroyed it. M. Broussonet, in the Mem. de l'Acad. des Sciences for the year 1784. p. 615. after having described the motion of the Dionaea, adds, that a similar appearance has been observed in the leaves of two species of Drosera.
Lonicera. l. 243. Caprifolium. Honeysuckle. Five males, one female. Nature has in many flowers used a wonderful apparatus to guard the nectary, or honey-gland, from infects. In the honey-suckle the petal terminates in a long tube like a cornucopiae, or horn of plenty; and the honey is produced at the bottom of it. In Aconitum, monks hood, the nectaries stand upright like two horns covered with a hood, which abounds with such acrid matter that no infects penetrate it. In Helleborus, hellebore, the many nectaries are placed in a circle, like little pitchers, and add much to the beauty of the flower. In the Columbine, Aquilegia, the nectary is imagined to be like the neck and body of a bird, and the two petals standing upon each side to represent wings; whence its name of columbine, as if resembling a nest of young pigeons fluttering whilst their parent feeds them. The importance of the nectary in the economy of vegetation is ex plained at large in the note on part the first.
Many infects are provided with a long and pliant proboscis for the purpose of acquiring this grateful food, as a variety of bees, moths, and butterflies: but the Sphinx Con volvuli, or unicorn moth, is furnished with the most remarkable proboscis in this climate. It carries it rolled up in concentric circles under its chin, and occasionally extends it to above three inches in length. This trunk consists of joints and muscles, and seems to have more versatile movements than the trunk of the elephant; and near its termination is split into two capillary tubes. The excellence of this contrivance for robbing the flowers of their honey, keeps this beautiful insect fat and bulky; though it flies only in the evening, when the flowers have closed their petals, and are thence more difficult of access; at the same time the brilliant colours of the moth contribute to its safety, by making it mistaken by the late sleeping birds for the flower it rests on.
Besides these there is a curious contrivance attending the Ophrys, commonly called the Bee-orchis, and the Fly-orchis, with some kinds of the Delphinium, called Bee larkspurs, to preserve their honey; in these the nectary and petals resemble in form and colour the insects, which plunder them: and thus it may be supposed, they often escape these hourly robbers, by having the appearance of being pre-occupied. See note on Rubia, and Conferva polymorpha.
Draba. l. 252. Alpina. Alpine Whitlow-grass. One female and six males. Four of these males stand above the other two; whence the name of the class "four powers." I have observed in several plants of this class, that the two lower males arise, in a few days after the opening of the flower, to the same height as the other four, not being mature as soon as the higher ones. See note on Gloriosa. All the plants of this class possess similar virtues; they are termed acrid and anti corbutic in their raw state, as mustard, watercress; when cultivated and boiled, they become a mild wholesome food, as cabbage, turnep.
There was formerly a Volcano on the Peake of Tenerif, which became extinct about the year 1684. Philos. Trans. In many excavations of the mountain, much below the summit, there is now found abundance of ice at all seasons. Tench's Expedition to Botany Bay, p. 12. Are these congelations in consequence of the daily solution of the hoar-frost which is produced on the summit during the night?
Viscum. l. 260. Misletoe. Two houses. This plant never grows upon the ground; the foliage is yellow, and the berries milk-white; the berries are so viscous, as to serve for bird-lime; and when they fall, adhere to the branches of the tree, on which the plant grows, and strike root into its bark; or are carried to distant trees by birds. The Til landsia, or wild pine, grows on other trees, like the Misletoe, but takes little or no nourishment from them, having large buckets in its leaves to collect and retain the rain water. See note on Dypsacus. The mosses, which grow on the bark of trees, take much nourishment from them; hence it is observed that trees, which are annually cleared from moss by a brush, grow nearly twice as fast. (Phil. Transact.) In the cyder coun tries the peasants brush their apple-trees annually.
Zostera. l. 266. Grass-wrack. Class, Feminine Males. Order, Many Males. It grows at the bottom of the sea, and rising to the surface, when in flower, covers many leagues; and is driven at length to the shore. During its time of floating on the sea, numberless animals live on the under surface of it, and being specifically lighter than the sea water, or being repelled by it, have legs placed as it were on their backs for the purpose of walking under it. As the Scylloea. See Barbut's Genera Vermium. It seems necessary that the marriages of plants should be celebrated in the open air, either because the powder of the anther, or the mucilage on the stigma, or the reservoir of honey might receive injury from the water. Mr. Needham observed, that in the ripe dust of every flower, examined by the microscope some vesicles are perceived, from which a fluid had escaped; and that those, which st••retain it, explode if they be wetted, like an eolopile suddenly exposed to a strong he••. These observations have been verified by Spallanzani and others. Hence rainy seasons make a scarcity of grain, or hinder its fecundity, by bursting the pollen before it arrives at the moist stigma of the flower. Spallanzani's Dissertations, v. II. p. 321. Thus the flowers of the male Val lisneria are produced under water, and when ripe detach themselves from the plant, and rising to the surface are wafted by the air to the female flowers.

Barometz. l. 284. Polypodium Barometz. Tartarian Lamb. Clandestine Marriage. This species of Fern is a native of China, with a decumbent root, thick, and every where covered with the most soft and dense wool, intensely yellow. Lin. Spec. Plant.
This curious stem is sometimes pushed out of the ground in its horizontal situation by some of the inferior branches of the root, so as to give it some resemblance to a Lamb standing on four legs; and has been said to destroy all other plants in its vicinity. Sir Hans Sloane describes it under the name of Tartarian Lamb, and has given a print of it. Philos. Trans. abridged, v. 11. p. 646. but thinks some art had been used to give it an animal appearance. Dr. Hunter, in his edition of the Terra of Evelyn, has given a more curious print of it, much resembling a sheep. The down is used in India exter nally for stopping hemorrhages, and is called golden moss.
The thick downy clothing of some vegetables seems designed to protect them from the injuries of cold, like the wool of animals. Those bodies, which are bad conductors of electricity, are also bad conductors of heat, as glass, wax, air. Hence either of the two former of these may be melted by the flame of a blow-pipe very near the fingers which hold it without burning them; and the last, by being confined on the surface of animal bodies, in the interstices of their fur or wool, prevents the escape of their natural warmth; to which should be added, that the hairs themselves are imperfect conductors. The fat or oil of whales, and other northern animals, seems designed for the same pur pose of preventing the too sudden escape of the heat of the body in cold climates. Snow protects vegetables which are covered by it from cold, both because it is a bad conductor of heat itself, and contains much air in its pores. If a piece of camphor be immersed in a snow-ball, except one extremity of it, on setting fire to this, as the snow melts, the water becomes absorbed into the surrounding snow by capillary, attraction; on this c count, when living animals are buried in snow, they are not most ned by it; but the cavity enlarges as the snow dissolves, affording them both a dry and warm habitation.
Mimosa. l. 321. The sensitive plant. Of the class Polygamy, one house. Naturalists 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, fold ing their upper surfaces together, and in part over each other like seales 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, since I have found, when touched in the night during their sleep, they fall still further; especially when touched on the foot-stalks between the stems and the leaflets, which seems 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 col lapse, may it not be owing to a numbness or paralysis consequent to too violent irri tation, like the saintings of animals from pain or fatigue? I kept a sensitive plant in a dark room till some hour after day-break; its leaves and leas-stalks were collapsed as in its most prosound sleep, and on exposing it to the light, above twenty minutes passed before the plant was thoroughly awake and had quite expanded itself. During the night the upper or smoother surfaces of the leaves are appressed together; 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. See note on Helianthus. Many flowers close up their petals during the night. See note on vegetable respiration in Part I.
Anemone. l. 318. Many males, many females. Pliny says this flower never opens its petals but when the wind blows; whence its name: it has properly no calix, but two or three sets of petals, three in each set, which are folded over the stamens and pistil in a singular and beautiful manner, and differs also from ranunculus in not having a melli ferous pore on the claw of each petal.
The Swallow. l. 322. There is a wonderful conformity between the vegetation of some plants, and the arrival of certain birds of passage. Linneus observes that the wood anemone blows in Sweden on the arrival of the swallow; and the marsh mary-gold, Caltha, when the cuckoo sings. Near the same coincidence was observed in England by Stillingfleet. The word Coccux in Greek signifies both a young fig and a cuckoo, which is supposed to have arisen from the coincidence of their appearance in Greece. Perhaps a similar coincidence of appearance in some parts of Asia gave occasion to the story of the loves of the rose and nightingale, so much celebrated by the eastern poets. See Dianthus. The times however of the appearance of vegetables in the spring seem occasionally to be influenced by their acquired habits, as well as by their sensibility to heat: for the roots of potatoes, onions, &c. will germinate with much less heat in the spring than in the autumn; as is easily observable where these roots are stored for use; and hence malt is best made in the spring. 2d. The grains and roots brought from more southern latitudes germinate here sooner than those which are brought from more northern ones, owing to their acquired habits. Fordyce on Agriculture. 3d. It was observed by one of the scholars of Linneus, that the apple-trees sent from hence to New England blossomed for a few years too early for that climate, and bore no fruit; but afterwards learnt to accommodate themselves to their new situation. (Kalm's Travels. ) 4th. The parts of animals become more sensible to heat after having been previously exposed to cold, as our hands glow on coming into the house after having held snow in them; this seems to happen to vegetables; for vines in grape-houses, which have been exposed to the winter's cold, will become forwarder and more vigorous than those which have been kept during the winter in the house. (Kenedy on Gardening.) This accounts for the very rapid vegetation in the northern latitudes after the solution of the snows.
The increase of the irritability of plants in respect to heat, after having been previ ously exposed to cold, is further illustrated by an experiment of Dr. Walker's. He cut apertures into a birch-tree at different heights; and on the 26th of March some of these apertures bled, or oozed with the sap-juice, when the thermometer was at 39; which same apertures did not bleed on the 13th of March, when the thermometer was at 44. The reason of this I apprehend was, because on the night of the 25th the thermometer was as low as 34; whereas on the night of the 12th it was at 41; though the ingenious author ascribes it to another cause. Trans. of Royal Soc. of Edinburgh, V. I. P. 19.
Lichen. l 349. Calcareum. Liver-wort. Clandestine Marriage. This plant is the first that vegetates on naked rocks, covering them with a kind of tapestry, and draws its nourishment perhaps chiefly from the air; after it perishes, earth enough is left for other mosses to root themselves; and after some ages a soil is produced sufficient for the growth of more succulent and large vegetables. In this manner perhaps the whole earth has been gradually covered with vegetation, after it was raised out of the primeval ocean by subterraneous fires.
Dypsacus. l. 367. Teasel. One female, and four males. There is a cup around every joint of the stem of this plant, which contains from a spoonful to half a pint of water; and serves both for the nutriment of the plant in dry seasons, and to prevent in sects from creeping up to devour its seed. See Silene. The Tillandsia, or wild pine, of the West Indies has every leaf terminated near the stalk with a hollow bucket, which contains from half a pint to a quart of water. Dampier's Voyage to Campeachy. Dr. Sloane mentions one kind of aloe furnished with leaves, which, like the wild pine and Banana, hold water; and thence afford necessary refreshment to travellers in hot coun tries. Nepenthes had a bucket for the same purpose at the end of every leaf. Burm. Zeyl. 42. 17.
Rubia. l. 375. Madder. Four males and one female. This plant is cultivated in very large quantities for dying red. If mixed with the food of young pigs or chickens, it colours their bones red. If they are fed alternate fortnights with a mixture of madder, and with their usual food alone, their bones will consist of concentric circles of white and red. Belchier, Phil. Trans. 1736. Animals fed with madder for the purpose of these experiments were found upon dissection to have thinner gall. Comment. de rebus. Lipsiae. This circumstance is worth further attention. The colouring materials of vege tables, like those which serve the purpose of tanning, varnishing, and the various medi cal purposes, do not seem essential to the life of the plant; but seem given it as a defence against the depredations of insects or other animals, to whom these materials are nauseous or deleterious. To insects and many smaller animals their colours contribute to conceal them from the larger ones which prey upon them. Caterpillars which feed on leaves are generally green; and earth-worms the colour of the earth which they inhabit; Butter flies, which frequent flowers, are coloured like them; small birds which frequent hedges have greenish backs like the leaves, and light coloured bellies like the sky, and are hence less visible to the hawk, who passes under them or over them. Those birds which are much amongst flowers, as the gold-finch (Fringilla carduelis), are furnished with vivid colours. The lark, partridge, hare, are the colour of the dry vegetables or earth on which they rest. And frogs vary their colour with the mud of the streams which they frequent; and those which live on trees are green. Fish, which are generally suspended in water, and swallows, which are generally suspended in air, have their backs the co lour of the distant ground, and their bellies of the sky. In the colder climates many of these become white during the existence of the snows. Hence there is apparent design in the colours of animals, whilst those of vegetables seem consequent to the other pro perties of the materials which possess them.
Pleased on the boiling wave. l. 387. The story of Aeson becoming young, from the medicated bath of Medea, seems to have been intended to teach the efficacy of warm bathing in retarding the progress of old age. The words relaxation and bracing, which are generally thought expressive of the effects of warm and cold bathing, are mechanical terms, properly applied to drums or strings; but are only metaphors when applied to the effects of cold or warm bathing on animal bodies. The immediate cause of old age seems to reside in the inirritability of the finer vessels or parts of our system; hence these cease to act, and collapse or become horny or bony. The warm bath is peculiarly adapted to prevent these circumstances by its increasing our irritability, and by moisten ing and softening the skin, and the extremities of the finer vessels, which terminate in it. To those who are past the meridian of life, and have dry skins, and begin to be emaciated, the warm bath, for half an hour twice a week, I believe to be eminently ferviceable in retarding the advances of age.
Vallisneria. l. 395. This extraordinary plant is of the class Two Houses. It is found in the East Indies, in Norway, and various parts of Italy. Lin. Spec. Plant. They have their roots at the bottom of the Rhone, the flowers of the female plant float on the sur face of the water, and are furnished with an elastic spiral stalk, which extends or contracts as the water rises and falls; this rise or fall, from the rapid descent of the river, and the mountain torrents which flow into it, often amounts to many feet in a few hours. The flowers of the male plant are produced under water, and as soon as their farina, or dust, is mature; they detach themselves from the plant, and rise to the surface, continue to flourish, and are wafted by the air, or borne by the currents to the female flowers. In this resembling those tribes of insects, where the males at certain seasons acquire wings, but not the females, as ants, Cocchus, Lampyris, Phalaena, Brumata, Lichanella. These male flowers are in such numbers, though very minute, as frequently to cover the surface of the river to considerable extent. See Families of Plants translated from Linnéus, P. 677.
Ulva. l. 407. Clandestine marriage. This kind of sea-weed is buoyed up by bladders of air, which are formed in the duplicatures of its leaves; and forms immense float ing fields of vegetation; the young ones, branching out from the larger ones, and borne on similar little air-vessels. It is also found in the warm baths of Patavia; where the leaves are formed into curious cells or labyrinths for the purpose of floating on the water. See ulva labyrinthi-formis Lin. Spec. Plant. The air contained in these cells was found by Dr. Priestley to be sometimes purer than common air, and sometimes less pure; the air-bladders of fish seem to be similar organs, and serve to render them buoyant in the water. In some of these, as in the Cod and Haddock, a red membrane, consisting of a great number of leaves or duplicatures, is sound within the air-bag, which probably secretes this air from the blood of the animal. (Monro. Physiol. of Fish. p. 28.) To determine whether this air, when first separated from the blood of the animal or plant, be dephlogisticated air, is worthy inquiry. The bladder-sena (Colutea), and bladder-nut (Staphylaea), have their seed-vessels distended with air; the Ketmia has the upper joint of the stem immediately under the receptacle of the flower much distended with air; these seem to be analogous to the air-vessel at the broad end of the egg, and may probably become less pure as the seed ripens: some, which I tried, had the purity of the surround ing atmosphere. The air at the broad end of the egg is probably an organ serving the purpose-of respiration to the young chick, some of whose vessels are spread upon it like a placenta, or permeate it. Many are of opinion that even the placenta of the human setus, and cotyledons of quadropeds, are respiratory organs rather than nutritious ones.
The air in the hollow stems of grasses, and of some umbelliserous plants, bears analogy to the air in the quills, and in some of the bones of birds; supplying the place of the pith, which shrivels up after it has performed its office of protruding the young stem or feather. Some of these cavities of the bones are said to communicate with the lungs in birds. Phil. Trans.
The air-bladders of fish are nicely adapted to their intended purpose; for though they render them buoyant near the surface without the labour of using their fins, yet, when they rest at greater depths, they are no inconvenience, as the increased pressure of the water condenses the air which they contain into less space. Thus, if a cork or bladder of air was immersed a very great depth in the ocean, it would be so much compressed, as to become specially as heavy as the water, and would remain there. It is probable the unfortunate Mr. Day, who was drowned in a diving-ship of his own construction, milcarried from not attending to this circumstance; it is probable the quantity of air he took down with him, if he descended much lower than he expected, was condensed into so small a space as not to render the ship buoyant when he endeavoured to ascend.
Tremella. l. 427. Clandestine marriage. I have frequently observed fungusses of this Genus on old rails and on the ground to become a transparent jelly, after they had been frozen in autumnal mornings; which is a curious property, and distinguishes them from some other vegetable mucilage; for I have observed that the paste, made by boiling wheat-flour in water, ceases to be adhesive after having been frozen. I suspected that the Tremella Nostoc, or star-jelly, also had been thus produced; but have since been well informed, that the Tremella Nostoc is a mucilage voided by Herons after they have eaten frogs; hence it has the appearance of having been pressed through a hole; and limbs of frogs are said sometimes to be found amongst it; it is always seen upon plains or by the sides of water, places which Herons generally frequent.
Some of the Fungusses are so acrid, that a drop of their juice blisters the tongue; others intoxicate those who eat them. The Ostiacks in Siberia use them for the latter purpose; one Fungus of the species, Agaricus muscarum, eaten raw; or the decoction of three of them, produces intoxication for 12 or 16 hours. History of Russia. V. I. Nichols. 1780. As all acrid plants become less so, if exposed to a boiling heat, it is probable the common mushroom may sometimes disagree from being not sufficiently stewed. The Ostiacks blister their skin by a fungus found on Birch-trees; and use the Agaricus officin. for Soap. ib.
There was a dispute whether the fungusses should be classed in the animal or vegetable department. Their animal taste in cookery, and their animal smell when burnt, toge ther with their tendency to putrefaction, insomuch that the Phallus impudicus has gained the name of stink-horn; and lastly, their growing and continuing healthy without light, as the Licoperdon tuber or truffle, and the fungus vinosus or mucor in dark cellars, and the esculent mushrooms on beds covered thick with straw, would seem to shew that they approach towards the animals, or make a kind of isthmus connecting the two mighty kingdoms of animal and of vegetable nature.
INTERLUDE.
YOUR verses, Mr. Botanist, consist of pure de scription, I hope there is sense in the notes.
I am only a flower-painter, or occasionally attempt a land skip; and leave the human figure with the subjects of history to abler artists.
It is well to know what subjects are within the limits of your pencil; many have failed of success from the want of this self knowledge. But pray tell me, what is the essential difference be tween Poetry and Prose? is it solely the melody or measure of the language?
I think not solely; for some prose has its melody, and even measure. And good verses, well spoken in a language unknown to the hearer, are not easily to be distinguished from good prose.
Is it the sublimity, beauty, or novelty of the sentiments?
Not so; for sublime sentiments are often better expressed in prose. Thus when Warwick in one of the plays of Shakespear, is left wounded on the field after the loss of the battle, and his friend says to him, "Oh, could you but fly!" what can be more sublime than his answer, "Why then, I would not fly." No measure of verse, I imagine, could add dignity to this sentiment. And it would be easy to select examples of the beautiful or new from prose writers, which I suppose no measure of verse could improve.
In what then consists the essential difference between Poetry and Prose?
Next to the measure of the language, the principal distinction appears to me to consist in this: that Poetry admits of but few words expressive of very abstracted ideas, whereas Prose abounds with them. And as our ideas derived from visible objects are more dis tinct than those derived from the objects of our other sense, the words expressive of these ideas belonging to vision make up the principal part of poetic language. That is, the Poet writes princi pally[Page 50] to the eye, the Prose-writer uses more abstracted terms. Mr. Pope has written a bad verse in the Windsor Forest:And Kennet swift for silver Eels renown'd. The word renown'd does not present the idea of a visible object to the mind, and is thence prosaic. But change this line thus,And Kennet swift, where silver Graylings play. and it becomes poetry, because the scenery is then brought before the eye.
This may be done in prose.
And when it is done in a single word, it animates the prose; so it is more agreeable to read in Mr. Gibbon's History,Germany was at this time over-shadowed with extensive forests;than Germany was at this time full of extensive forests. But where this mode of expression occurs too frequently, the prose approaches to poetry: and in graver works, where we expect to be instructed ra ther than amused, it becomes tedious and impertinent. Some parts of Mr. Burke's eloquent orations become intricate and enervated by superfluity of poetic ornament; which quantity of ornament would have been agreeable in a poem, where much ornament is ex pected.
Is then the office of Poetry only to amuse?
The Muses are young ladies, we expect to see them dressed; though not like some modern beauties with so much gauze and fea ther, that "the Lady herself is the least part of her." There are however didactic pieces of poetry, which are much admired, as the Georgics of Virgil, Mason's English Garden, Hayley's Epistles; nevertheless Science is best delivered in Prose, as its mode of reason ing is from stricter analogies than metaphors or similies.
Do not Personifications and Allegories distinguish poetry?
These are other arts of bringing objects before the eye; or of expressing sentiments in the language of vision; and are indeed better suited to the pen than the pencil.
That is strange, when you have just said they are used to bring their objects before the eye.
In poetry the personification or allegoric figure is generally indistinct, and therefore does not strike us so forcibly as to make us attend to its improbability; but in painting, the figures being all[Page 52] much more distinct, their improbability becomes apparent, and seizes our attention to it. Thus the person of Concealment is very indis tinct, and therefore does not compel us to attend to its improbability, in the following beautiful lines of Shakespear:
But in these lines below the person of Reason obtrudes itself into our company, and becomes disagreeable by its distinctness, and cones quent improbability.
Allegoric figures are on this account in general less manageable in painting and in statuary than in poetry: and can seldom be intro duced in the two former arts in company with natural figures, as is evident from the ridiculous effect of many of the paintings of Rubens in the Luxemburgh gallery; and for this reason, because their im probability becomes more striking, when there are the figures of real persons by their side to compare them with.
[Page 53]Mrs. Angelica Kauffman, well apprised of this circumstance, has introduced no mortal figures amongst her Cupids and her Graces. And the great Roubiliac, in his unrivalled monument of Time and Fame struggling for the trophy of General Fleming, has only hung up a medallion of the head of the hero of the piece. There are however some allegoric figures, which we have so often heard described or seen delineated, that we almost forget that they do not exist in common life; and hence view them without astonishment; as the figures of the heathen mythology, of angels, devils, death and time; and almost believe them to be realities, even when they are mixed with representations of the natural forms of man. Whence I con clude, that a certain degree of probability is necessary to prevent us from revolting with distaste from unnatural images; unless we are otherwise so much interested in the contemplation of them as not to perceive their improbability.
Is this reasoning about degrees of probability just? — When Sir Joshua Reynolds, who is unequalled both in the theory and practice of his art, and who is a great master of the pen as well as the pencil, has asserted in a discourse delivered to the Royal Academy, December 11, 1786, thatthe higher styles of painting, like the higher kinds of the Drama, do not aim at any thing like deception; or have any expectation, that the spectators should think the events there represented are really passing before them.And he then accuses Mr. Fielding of bad judgment, when he attempts to compliment Mr. Garrick in one of his novels, by introducing an ignorant man, mistaking the representation of a scene in Hamlet for a reality; and[Page 54] thinks, because he was an ignorant man, he was less liable to make such a mistake.
It is a metaphysical question, and requires more attention than Sir Joshua has bestowed upon it. — You will allow, that we are per fectly deceived in our dreams; and that even in our waking reveries, we are often so much absorbed in the contemplation of what passes in our imaginations, that for a while we do not attend to the lapse of time or to our own locality; and thus suffer a similar kind of de ception as in our dreams. That is, we believe things present before our eyes, which are not so.
There are two circumstances, which contribute to this compleat deception in our dreams. First, because in sleep the organs of sense are closed or inert, and hence the trains of ideas associated in our imaginations are never interrupted or disserered by the irritations of external objects, and can not therefore be contrasted with our sen sations. On this account, though we are affected with a variety of passions in our dreams, as anger, love, joy; yet we never experience surprize. — For surprize is only produced when any external irrita tions suddenly obtrude themselves, and dissever our passing trains of ideas.
Secondly, because in sleep there is a total suspension of our volun tary power, both over the muscles of our bodies, and the ideas of our minds; for we neither walk about, nor reason in compleat sleep. Hence, as the trains of ideas are passing in our imaginations in dreams, we cannot compare them with our previous knowledge of things, as we do in our waking hours; for this is a voluntary exertion; and thus we cannot perceive their incongruity.
[Page 55]Thus we are deprived in sleep of the only two means by which we can distinguish the trains of ideas passing in our imaginations, from those excited by our sensations; and are led by their vivacity to be lieve them to belong to the latter. For the vivacity of these trains of ideas, passing in the imagination, is greatly increased by the causes above-mentioned; that is, by their not being disturbed or dissevered either by the appulses of external bodies, as in surprize; or by our voluntary exertions in comparing them with our previous knowledge of things, as in reasoning upon them.
Now to apply.
When by the art of the Painter or Poet a train of ideas is sug gested to our imaginations, which interests us so much by the pain or pleasure it affords, that we cease to attend to the irritations of common external objects, and cease also to use any voluntary efforts to compare these interesting trains of ideas with our previous know ledge of things, a compleat reverie is produced: during which time, however short, if it be but for a moment, the objects themselves appear to exist before us. This, I think, has been called by an in genious critic "the ideal presence" of such objects. (Elements of Criticism by Lord Kaimes). And in respect to the compliment in tended by Mr. Fielding to Mr. Garrick, it would seem that an ig norant Rustic at the play of Hamlet, who has some previous belief in the appearance of Ghosts, would sooner be liable to fall into re verie, and continue in it longer, than one who possessed more know ledge[Page 56] of the real nature of things, and had a greater facility of ex ercising his reason.
It must require great art in the Painter or Poet to produce this kind of deception?
The matter must be interesting from its sublimity, beauty, or novelty; this is the scientific part; and the art consists in bringing these distinctly before the eye, so as to produce (as above-mentioned) the ideal presence of the object, in which the great Shakespear par ticularly excells.
Then it is not of any consequence whether the representations correspond with nature?
Not if they so much interest the reader or spectator as to in duce the reverie above described. Nature may be seen in the market place, or at the card-table; but we expect something more than this in the play-house or picture-room. The further the artists recedes from nature, the greater novelty he is likely to produce; if he rises above nature, he produces the sublime; and beauty is probably a selection and new combination of her most agreeable parts. Your self will be sensible of the truth of this doctrine by recollecting over[Page 57] in your mind the works of three of our celebrated artists. Sir Joshua Reynolds has introduced sublimity even into its protraits; we admire the representation of persons, whose reality we should have passed by unnoticed. Mrs. Angelica Kauffman attracts our eyes with beauty, which I suppose no where exists; certainly few Grecian faces are seen in this country. And the daring pencil of Fuseli transports us beyond the boundaries of nature, and ravishes us with the charm of the most interesting novelty. And Shakespear, who excells in all these together, so far captivates the spectator, as to make him un mindful of every kind of violation of Time, Place, or Existence. As at the first appearance of the Ghost of Hamlet,his ear must be dull as the fat weed, which roots itself on Lethe's brink,who can attend to the improbality of the exhibition. So in many scenes of the Tempest we perpetually believe the action passing before our eyes, and relapse with somewhat of distaste into common life at the intervals of the representation.
I suppose a poet of less ability would find such great machi nery difficult and cumbersome to manage?
Just so, we should be shocked at the apparent improbabilities. As in the gardens of a Scicilian nobleman, described in Mr. Brydone's and in Mr. Swinburn's travels, there are said to be fix hundred statues of imaginary monsters, which so disgust the spectators, that the state had once a serious design of destroying them; and yet the very[Page 58] improbable monsters in Ovid's Metamorphoses have entertained the world for many centuries.
The monsters in your Botanic Garden, I hope, are of the latter kind?
The candid reader must determine.
THE LOVES OF THE PLANTS.
CANTO II.
Carlina. l. 7. Carline Thistle. Of the class Confederate Males. The feeds of this and of many other plants of the same class are furnished with a plume, by which ad mirable mechanism they perform long aërial journeys, crossing lakes and deserts, and are thus disseminated far from the original plant, and have much the appearance of a Shut tlecock as they fly. The wings are of different construction, some being like a diver gent tuft of hairs, others are branched like feathers, some are elevated from the crown of the feed by a slender foot-stalk, which gives them a very elegant appearance, others sit immediately on the crown of the seed.
Nature has many other curious vegetable contrivances for the dispersion of seeds: see note on Helianthus. But perhaps none of them has more the appearance of design than the admirable apparatus of Tillandsia for this purpose. This plant grows on the branches of trees, like the misleto, and never on the ground; the seeds are furnished with many long threads on their crowns; which, as they are driven forwards by the winds, wrap round the arms of trees, and thus hold them last till they vegetate. This is very analogous to the migration of Spiders on the gossamer, who are said to attach themselves to the end of a long thread, and rise thus to the tops of trees or buildings, as the accidental breezes carry them.
For thee the Bear. l. 60. Tibi jam brachia contrahit ardens Scorpius. Virg. Georg. l. 1. 34. A new star appeared in Cassiope's chair in 1572. Herschel's Construction of the Heavens. Phil. Trans. V. 75. p. 266.
Linum. l. 67. Flax Five males and five females. It was first found on the banks of the Nile. The Linum Lusitanicum, or portigal flax, has ten males: see the note on Curcuma. Isis was said to invent spinning and weaving: mankind before that time were clothed with the skins of animals. The fable of Arachne was to compliment this new art of spinning and weaving, supposed to surpass in fineness the web of the Spider.
Gossypia. l. 87. Gossypium. The cotton plant. On the river Derwent near Matlock in Derbyshire, Sir RICHARD ARKWRIGHT has erected his curious and magnificent machinery for spinning cotton; which had been in vain attempted by many ingenious artists before him. The cotton-wool is first picked from the pods and seeds by women. It is then c•rded by cylindrical cards which move against each other, with different ve locities. It is taken from these by an iron-hand or comb, which has a motion similar to that of scratching, and takes the wool off the cards longitudinally in respect to the fibres or staple, producing a continued line loosely cohering, called the Rove or Roving. This Rove, yet very loosely twisted, is then received or drawn into a whirling canister, and is rolled by the centrifugal force in spiral lines within it; being yet too tender for the spindle. It is then passed between two pairs of rollers; the second pair moving faster than the first elongate the thread with greater equality than can be done by the hand; and is then twisted on spoles or bobbins.
The great fertility of the Cotton-plant in these fine flexile threads, whilst these from Flax, Hemp, and Nettles, or from the bark of the Mulberry-tree, require a previous pu trefection of the parenchymatous substance, and much mechanical labour, and afterwards bleaching, renders this plant of great importance to the world. And since Sir Richard Arkwright's ingenious machine has not only greatly abbreviated and simplesied the labour and art of carding and spinning the Cotton-wool, but performs both these cir cumstances better than can be done by hand, it is probable, that the clothing of this snall seed will become the principal clothing of mankind; though animal wool and silk may be preferable in colder climates, as they are more imperfect conductors of heat, and are thence a warmer clothing.
Cyperus. Papyrus. l. 105. Three males, one female. The leaf of this plant was first used for paper, whence the word paper; and leaf, or folium, for a fold of a book. Af terwards the bark of a species of mulberry was used; whence liber signifies a book, and the bark of a tree. Before the invention of letters mankind may be said to have been perpatually in their infancy, as the arts of one age or country generally died with their inventors. Whence arose the policy, which still continues in Indostan, of obliging the son to practise the profession of his father. After the discovery of letters, the facts of Astronomy and Chemistry became recorded in written language, though the antient hieroglyphic characters for the planets and metals continue in use at this day. The an tiquity of the invention of music, of astronomical observations, and the manufacture of Gold and Iron, are recorded in Scripture.
About twenty letters, ten cyphers, and seven crotches, represent by their numerous combinations all our ideas and sensations! the musical characters are probably arrived at their perfection, unless emphasis, and tone, and swell could be exprssed, as well as note and time. Charles the Twelfth of Sweden had a design
