Now the broad Sun his golden orb unshrouds, Flames in the west, and paints the parted clouds; O'er heaven's wide arch refracted lustres flow, And bend in air the many-colour'd bow.-- 5 --The tuneful Goddess on the glowing sky Fix'd in mute extacy her glistening eye; And then her lute to sweeter tones she strung, And swell'd with softer chords the Paphian song. Long ailes of Oaks return'd the silver sound, 10 And amorous Echoes talk'd along the ground; Pleas'd Lichfield listen'd from her sacred bowers, Bow'd her tall groves, and shook her stately towers.

"Nymph! not for thee the radiant day returns, Nymph! not for thee the golden solstice burns, 15 Refulgent CEREA!--at the dusky hour She seeks with pensive step the mountain-bower,

[_Pleas'd Lichfield._ I. 11. The scenery described at the beginning of the first part, or economy of vegetation, is taken from a botanic garden about a mile from Lichfield.

_Cerea._ l. 15. Cactus grandiflorus, or Cereus. Twenty males, one female. This flower is a native of Jamaica and Veracrux. It expands a most exquisitely beautiful corol, and emits a most fragrant odour for a few hours in the night, and then closes to open no more. The flower is nearly a foot in diameter; the inside of the calyx of a splendid yellow, and the numerous petals of a pure white: it begins to open about seven or eight o'clock in the evening, and closes before sun-rise in the morning. Martyn's Letters, p. 294. The Cistus labdiniferus, and many other flowers, lose their petals after having been a few hours expanded in the day-time; for in these plants the stigma is soon impregnated by the numerous anthers: in many flowers of the Cistus lubdiniferus I observed two or three of the stamens were perpetually bent into contact with the pistil.

The Nyctanthes, called Arabian Jasmine, is another flower, which expands a beautiful corol, and gives out a most delicate perfume during the night, and not in the day, in its native country, whence its name; botanical philosophers have not yet explained this wonderful property; perhaps the plant sleeps during the day as some animals do; and its odoriferous glands only emit their fragrance during the expansion of the petals; that is, during its waking hours: the Geranium triste has the same property of giving up its fragrance only in the night. The flowers of the Cucurbita lagenaria are said to close when the sun shines upon them. In our climate many flowers, as tragopogon, and hibiscus, close their flowers before the hottest part of the day comes on; and the flowers of some species of cucubalus, and Silene, viscous campion, are closed all day; but when the sun leaves them they expand, and emit a very agreeable scent; whence such plants are termed noctiflora.]

Bright as the blush of rising morn, and warms The dull cold eye of Midnight with her charms. There to the skies she lifts her pencill'd brows, 20 Opes her fair lips, and breathes her virgin vows; Eyes the white zenyth; counts the suns, that roll Their distant fires, and blaze around the Pole; Or marks where Jove directs his glittering car O'er Heaven's blue vault,--Herself a brighter star. 25 --There as soft Zephyrs sweep with pausing airs Thy snowy neck, and part thy shadowy hairs, Sweet Maid of Night! to Cynthia's sober beams Glows thy warm cheek, thy polish'd bosom gleams. _In crowds_ around thee gaze the admiring swains, 30 And guard in silence the enchanted plains; Drop the still tear, or breathe the impassion'd sigh, And drink inebriate rapture from thine eye. Thus, when old Needwood's hoary scenes the Night Paints with blue shadow, and with milky light; 35 Where MUNDY pour'd, the listening nymphs among, Loud to the echoing vales his parting song; With measured step the Fairy Sovereign treads, Shakes her high plume, and glitters o'er the meads; Round each green holly leads her sportive train, 40 And little footsteps mark the circled plain; Each haunted rill with silver voices rings, And Night's sweet bird in livelier accents sings.

Ere the bright star, which leads the morning sky, Hangs o'er the blushing east his diamond eye, 45 The chaste TROPAEO leaves her secret bed; A saint-like glory trembles round her head;

[_ Where Mundy._ l. 35. Alluding to an unpublished poem by F. N. Mundy, Esq. on his leaving Needwood-Forest.

_Tropæolum._ l. 45. Majus. Garden Nasturtion, or greater Indian cress. Eight males, one female. Miss E. C. Linneus first observed the Tropæolum Majus to emit sparks or flashes in the mornings before sun-rise, during the months of June or July, and also during the twilight in the evening, but not after total darkness came on; these singular scintillations were shewn to her father and other philosophers; and Mr. Wilcke, a celebrated electrician, believed them to be electric. Lin. Spec. Plantar. p. 490. Swedish Acts for the year 1762. Pulteney's View of Linneus, p. 220. Nor is this more wonderful than that the electric eel and torpedo should give voluntary shocks of electricity; and in this plant perhaps, as in those animals, it may be a mode of defence, by which it harrasses or destroys the night-flying insects which infest it; and probably it may emit the same sparks during the day, which must be then invisible. This curious subject deserves further investigation. See Dictamnus. The ceasing to shine of this plant after twilight might induce one to conceive, that it absorbed and emitted light, like the Bolognian Phosphorus, or calcined oyster-shells, so well explained by Mr. B. Wilson, and by T. B. Beccari. Exper. on Phosphori, by B. Wilson. Dodsley. The light of the evening, at the same distance from noon, is much greater, as I have repeatedly observed, than the light of the morning: this is owing, I suppose, to the phosphorescent quality of almost all bodies, in a greater or less degree, which thus absorb light during the sun-shine, and continue to emit it again for some time afterwards, though not in such quantity as to produce apparent scintillations. The nectary of this plant grows from what is supposed to be the calyx; but this supposed calyx is coloured; and perhaps, from this circumstance of its bearing the nectary, should rather be esteemed a part of the coral. See an additional note at the end of the poem.]

_Eight_ watchful swains along the lawns of night With amorous steps pursue the virgin light; O'er her fair form the electric lustre plays, 50 And cold she moves amid the lambent blaze. So shines the glow-fly, when the sun retires, And gems the night-air with phosphoric fires;

[_So shines the glow-fly._ l. 52. In Jamaica, in some seasons of the year, the fire-flies are seen in the evenings in great abundance. When they settle on the ground, the bull-frog greedily devours them; which seems to have given origin to a curious, though cruel, method of destroying these animals: if red-hot pieces of charcoal be thrown towards them in the dusk of the evening, they leap at them, and, hastily swallowing them, are burnt to death.]

Thus o'er the marsh aërial lights betray, And charm the unwary wanderer from his way. 55 So when thy King, Assyria, fierce and proud, Three human victims to his idol vow'd; Rear'd a vast pyre before the golden shrine Of sulphurous coal, and pitch-exsuding pine;-- --Loud roar the flames, the iron nostrils breathe, 60 And the huge bellows pant and heave beneath; Bright and more bright the blazing deluge flows, And white with seven-fold heat the furnace glows. And now the Monarch fix'd with dread surprize Deep in the burning vault his dazzled eyes. 65 "Lo! Three unbound amid the frightful glare, Unscorch'd their sandals, and unsing'd their hair! And now a fourth with seraph-beauty bright Descends, accosts them, and outshines the light! Fierce flames innocuous, as they step, retire! 70 And slow they move amid a world of fire!" He spoke,--to Heaven his arms repentant spread, And kneeling bow'd his gem-incircled head. _Two_ Sister-Nymphs, the fair AVENAS, lead Their fleecy squadrons on the lawns of Tweed; 75 Pass with light step his wave-worn banks along, And wake his Echoes with their silver tongue; Or touch the reed, as gentle Love inspires, In notes accordant to their chaste desires.

"Sweet ECHO! sleeps thy vocal shell, "Where this high arch o'erhangs the dell; "While Tweed with sun-reflecting streams "Chequers thy rocks with dancing beams?--

[_Ovena_. l. 73. Oat. The numerous families of grasses have all three males, and two females, except Anthoxanthum, which gives the grateful smell to hay, and has but two males. The herbs of this order of vegetables support the countless tribes of graminivorous animals. The seeds of the smaller kinds of grasses, as of aira, poa, briza, stipa, &c. are the sustenance of many sorts of birds. The seeds of the large grasses, as of wheat, barley, rye, oats, supply food to the human species.

It seems to have required more ingenuity to think of feeding nations of mankind with so small a seed, than with the potatoe of Mexico, or the bread-fruit of the southern islands; hence Ceres in Egypt, which was the birth-place of our European arts, was deservedly celebrated amongst their divinities, as well as Osyris, who invented the Plough.

Mr. Wahlborn observes, that as wheat, rye, and many of the grasses, and plantain, lift up their anthers on long filments, and thus expose the enclosed fecundating dust to be washed away by the rains, a scarcity of corn is produced by wet summers; hence the necessity of a careful choice of seed wheat, as that, which had not received the dust of the anthers, will not grow, though it may appear well to the eye. The straw of the oat seems to have been the first musical instrument, invented during the pastoral ages of the world, before the discovery of metals. See note on Cistus.]

"Here may no clamours harsh intrude, No brawling hound or clarion rude; 85 Here no fell beast of midnight prowl, And teach thy tortured cliffs to howl!

III.

"Be thine to pour these vales along Some artless Shepherd's evening song; While Night's sweet bird, from yon high spray 90 Responsive, listens to his lay.

IV.

"And if, like me, some love-lorn maid "Should sing her sorrows to thy shade, "Oh, sooth her breast, ye rocks around! "With softest sympathy of sound."

95 From ozier bowers the brooding Halcyons peep, The Swans pursuing cleave the glassy deep, On hovering wings the wondering Reed-larks play, And silent Bitterns listen to the lay.-- _Three_ shepherd-swains beneath the beechen shades 100 Twine rival garlands for the tuneful maids; On each smooth bark the mystic love-knot frame, Or on white sands inscribe the favour'd name.

From Time's remotest dawn where China brings In proud succession all her Patriot-Kings; 105 O'er desert-sands, deep gulfs, and hills sublime, Extends her massy wall from clime to clime; With bells and dragons crests her Pagod-bowers, Her silken palaces, and porcelain towers; With long canals a thousand nations laves; 110 Plants all her wilds, and peoples all her waves; Slow treads fair CANNABIS the breezy strand, The distaff streams dishevell'd in her hand;

[_Cannabis_. l. 111. Chinese Hemp. Two houses. Five males. A new species of hemp, of which an account is given by K. Fitzgerald, Esq. in a letter to Sir Joseph Banks, and which is believed to be much superior to the hemp of other countries. A few seeds of this plant were sown in England on the 4th of June, and grew to fourteen feet seven inches in height by the middle of October; they were nearly seven inches in circumference, and bore many lateral branches, and produced very white and tough fibres. At some parts of the time these plants grew nearly eleven inches in a week. Philos. Trans. Vol. LXXII. p. 46.]

Now to the left her ivory neck inclines, And leads in Paphian curves its azure lines; 115 Dark waves the fringed lid, the warm cheek glows, And the fair ear the parting locks disclose; Now to the right with airy sweep she bends, Quick join the threads, the dancing spole depends. --_Five_ Swains attracted guard the Nymph, by turns 120 Her grace inchants them, and her beauty burns; To each She bows with sweet assuasive smile, Hears his soft vows, and turns her spole the while.

So when with light and shade, concordant strife! Stern CLOTHO weaves the chequer'd thread of life; 125 Hour after hour the growing line extends, The cradle and the coffin bound its ends;

[_Paphian curves._ l. 114. In his ingenious work, entitled, The Analysis of Beauty, Mr. Hogarth believes that the triangular glass, which was dedicated to Venus in her temple at Paphos, contained in it a line bending spirally round a cone with a certain degree of curviture; and that this pyramidal outline and serpentine curve constitute the principles of Grace and Beauty.]

Soft cords of silk the whirling spoles reveal, If smiling Fortune turn the giddy wheel; But if sweet Love with baby-fingers twines, 130 And wets with dewy lips the lengthening lines, Skein after skein celestial tints unfold, And all the silken tissue shines with gold.

Warm with sweet blushes bright GALANTHA glows, And prints with frolic step the melting snows;

[_Galanthus._ l. 133. Nivalis. Snowdrop. Six males, one female. The first flower that appears after the winter solstice. See Stillingfleet's Calendar of Flora.

Some snowdrop-roots taken up in winter, and boiled, had the insipid mucilaginous taste of the Orchis, and, if cured in the same manner, would probably make as good salep. The roots of the Hyacinth, I am informed, are equally insipid, and might be used as an article of food. Gmelin, in his History of Siberia, says the Martigon Lily makes a part of the food of that country, which is of the same natural order as the snowdrop. Some roots of Crocus, which I boiled, had a disagreeable flavour.

The difficulty of raising the Orchis from seed has, perhaps, been a principal reason of its not being cultivated in this country as an article of food. It is affirmed, by one of the Linnean school, in the Amoenit. Academ. that the seeds of Orchis will ripen, if you destroy the new bulb; and that Lily of the Valley, Convallaria, will produce many more seeds, and ripen them, if the roots be crowded in a garden-pot, so as to prevent them from producing many bulbs. Vol. VI. p. 120. It is probable either of these methods may succeed with these and other bulbous-rooted plants, as snowdrops, and might render their cultivation profitable in this climate. The root of the asphodelus ramosus, branchy asphodel, is used to feed swine in France; and starch is obtained from the alstromeria licta. Memoires d'Agricult.]

135 O'er silent floods, white hills, and glittering meads _Six_ rival swains the playful beauty leads, Chides with her dulcet voice the tardy Spring, Bids slumbering Zephyr stretch his folded wing, Wakes the hoarse Cuckoo in his gloomy cave, 140 And calls the wondering Dormouse from his grave, Bids the mute Redbreast cheer the budding grove, And plaintive Ringdove tune her notes to love.

Spring! with thy own sweet smile, and tuneful tongue, Delighted BELLIS calls her infant throng. 145 Each on his reed astride, the Cherub-train Watch her kind looks, and circle o'er the plain; Now with young wonder touch the siding snail, Admire his eye-tipp'd horns, and painted mail; Chase with quick step, and eager arms outspread, 150 The pausing Butterfly from mead to mead;

[_Bellis prolifera_ l. 144. Hen and chicken Daisy; in this beautiful monster not only the impletion or doubling of the petals takes place, as described in the note on Alcea; but a numerous circlet of less flowers on peduncles, or footstalks, rise from the sides of the calyx, and surround the proliferous parent. The same occurs in Calendula, marigold; in Heracium, hawk-weed; and in Scabiosa, Scabious. Phil. Botan. p. 82.]

Or twine green oziers with the fragrant gale, The azure harebel, and the primrose pale, Join hand in hand, and in procession gay Adorn with votive wreaths the shrine of May. 155 --So moves the Goddess to the Idalian groves, And leads her gold-hair'd family of Loves. These, from the flaming furnace, strong and bold Pour the red steel into the sandy mould; On tinkling anvils (with Vulcanian art), 160 Turn with hot tongs, and forge the dreadful dart; The barbed head on whirling jaspers grind, And dip the point in poison for the mind; Each polish'd shaft with snow-white plumage wing, Or strain the bow reluctant to its string. 165 Those on light pinion twine with busy hands, Or stretch from bough to bough the flowery bands;

[_The fragrant Gale._ l. 151. The buds of the Myrica Gale possess an agreeable aromatic fragrance, and might be worth attending to as an article of the Materia Medica. Mr. Sparman suspects, that the green wax-like substance, with which at certain times of the year the berries of the Myrica cerifera, or candle-berry Myrtle, are covered, are deposited there by insects. It is used by the inhabitants for making candles, which he says burn rather better than those made of tallow. _Voyage to the Cape,_ V. I. 345.]

Scare the dark beetle, as he wheels on high, Or catch in silken nets the gilded fly; Call the young Zephyrs to their fragrant bowers, 170 And stay with kisses sweet the Vernal Hours. Where, as proud Maffon rises rude and bleak, And with mishapen turrets crests the Peak, Old Matlock gapes with marble jaws, beneath, And o'er fear'd Derwent bends his flinty teeth; 175 Deep in wide caves below the dangerous soil Blue sulphurs flame, imprison'd waters boil.

[_Deep in wide caves_. l. 175. The arguments which tend to shew that the warm springs of this country are produced from steam raised by deep subterraneous fires, and afterwards condensed between the strata of the mountains, appear to me much more conclusive, than the idea of their being warmed by chemical combinations near the surface of the earth: for, 1st, their heat has kept accurately the same perhaps for many centuries, certainly as long as we have been possessed of good thermometers; which cannot be well explained, without supposing that they are first in a boiling state. For as the heat of boiling water is 212, and that of the internal parts of the earth 48, it is easy to understand, that the steam raised from boiling water, after being condensed in some mountain, and passing from thence through a certain space of the cold earth, must be cooled always to a given degree; and it is probable the distance from the exit of the spring, to the place where the steam is condensed, might be guessed by the degree of its warmth.

2. In the dry summer of 1780, when all other springs were either dry or much diminished, those of Buxton and Matlock (as I was well informed on the spot), had suffered no diminution; which proves that the sources of these warm springs are at great depths below the surface of the earth.

3. There are numerous perpendicular fissures in the rocks of Derbyshire, in which the ores of lead and copper are found, and which pass to unknown depths; and might thence afford a passage to steam from great subterraneous fires.

4. If these waters were heated by the decomposition of pyrites, there would be some chalybeate taste or sulphureous smell in them. See note in
