Dozens of sphinx moths--big torpedo-shaped bodies carried by wings of soft brown and dull red--floated about, sipping where and when and as long as they liked. Sometimes the sphinx has almost an aggressive tone In his flight--hasty, important, brooking no interference. Last night's note was of supreme content. A rich and overflowing feast was spread and the insects hovered over the posies and sipped and fluted like merry roysterers, without a care or thought of the morrow. It was a love-feast, for the still night seemed to invite the trees to give of their richest and best; the psalm of the insects was audible, not to the distance whence the perfume was dissipated, but for many a scented yard.

The trees seemed sanctified, and I stood bare-headed among them and gave my silent praise for a delightsome experience. Expectancy and patience had been overpaid.

THE SCENE-SHIFTER

"We are all going to the play or coming from it."--d.i.c.kENS.

In a few hours came "the season's difference." The scene-shifter worked with almost magical haste, with silence, and with supreme effect. The gloomy days and nights of misty hill-tops and damp hollows, where the gra.s.s was sodden and the air dull and irresponsive to sound, gave way to bright sunshine, cloudless skies, calm seas, echoing hills, and the tinge of that which for lack of the ideal word we call "spring." Spring does not visit the tropical coast, where vegetation does not tolerate any period of rest. When plants are not actually romping with excess of vital force, as during the height of the wet season, they grow with the haste of summer. And yet immediately on the dispersal of the mists of July the least observance could not fail to recognise that a certain and elaborate change had taken place. The mango-trees had been flowering for several weeks in a trivial, half-hearted way, but when the sun sent its thrills down into the moist soil the lemons and pomeloes began to sweeten the air; the sunflower-tree displayed its golden crowns among huge soft leaves, and the last blooms of belated wattles fell, showing that it is possible for tributes representative of May and September to be paid on one and the same date.

The scene-shifter came softly "as the small rain upon the tender herb,"

but with an orchestra of his own. Years of observation have shown that the weather does control the habits of some birds--birds of distinct and regular methods of life. Two such are common--the nutmeg pigeon and the metallic starling. Both species leave this part of the North during the third week of March, flying in flocks to regions nearer the equator.

For several weeks the starlings train themselves for the long Northern flight and its perils, dashing with impetuous speed through the forest and wheeling up into the sky until they disappear, to become visible again as black dots hurtling through s.p.a.ce when the sunlight plays on their glossy feathers as the course of the flock is changed. With the rush of a wind of small measure but immense velocity, the flock descends earthwards, among and over the trees, perfecting itself by trials of endurance and intricate alertness. The birds return during the first week in August, in small and silent companies, to reoccupy favourite resorts in common. The nutmeg pigeons are also of exact habit, the time for their return generally coinciding with that of the starlings. This year (1916) both birds were noticed just after the scene-shifter had swept the hills of mists, and now other birds seem to have awakened to the conditions which the starlings and the nutmegs brought with them from hotter lands. The swamp pheasants are whooping and gurgling, and that semi-migratory fellow, the spangled drongo--a flattering name, for he jangles but does not spangle--sits on the slim branch of the Moreton Bay ash which held last year's nest and chatters discordances in the very ears of his responsive mate. They will start building a loose nest on the brittlest branch forthwith, and while the lady sits on her three eggs he will screech defiances to the high heavens and perform aerial gymnastics with delirious delight.

The sun-birds are searching the lemon blooms. The breast of the gay, a.s.sertive little bird is far richer in tint than the brightest of the lemons. A minute ago one perched on a ripe fruit as if to shame it by contrast, and the fruit has since seemed a trifle dull of tint, and with light-hearted inconsequence the pair are now probing narrow throats of papaw flowers. The ground has been too much overgrown with gra.s.s and weeds for the comfort of the little green pigeons which come strutting down the paths for seeds and crumbs. Dry soil, which may be easily scanned and scratched, is more to their liking, so they keep to the forest, where in some places the undergrowth of wattles is so dense that the sun may not visit the ground, and the bare places glitter with seed.

When rain was seriously deficient, proof was given that some proportion of the wattle seeds eaten by pigeons are not digested. In the crevices of logs supporting the water-trough, which proved to be a popular refreshment spot of many species of birds, clamorous with thirst, seeds were deposited, and when the rains came the trough was fringed and decorated with pinnate leaves of sprouting wattles, some of which grew so strongly, notwithstanding the absence of soil, save that which occurs from the slow decay of seasoned bloodwood, that if summary measures had not been taken the trough might have been embowered. The season seems to have been too damp for the night-jars, though quite to the taste of all species of pigeons. In the course of a few minutes the voice of the timid, tremulous, barred-shouldered dove came from among the yellow-flowered hibiscus of the beach, while the pheasant-tailed pigeon sounded its rich, dual note, the red-crowned fruit pigeon tolled its mournful chime, and the guttural of the magnificent fruit pigeon--often heard, but seldom seen--came from the jungle close at hand. Not one of these birds was visible, nor was the fluty-voiced shrike thrush, which answers every strange call and mimics crude attempts to reproduce its varied notes. The blue kingfisher is investigating the tumour made by white ants in the bloodwood wherein the nest is annually excavated, and soon the chattering notes of the pair will be heard. A week ago few signs of the approach of the scene-shifter were discernible. He has come, and plants and birds respond to his genial and becoming presence--plants with richer growth and more abundant flowers, birds with the unreflecting gaiety of nuptial days.

BEACH PLANTS

"Remove the vegetable kingdom, or interrupt the flow of its unconscious benefactions, and the whole higher life of the world ends."--HENRY DRUMMOND.

Strolling on the curving footway of broken sh.e.l.ls and coral chips marking the limit of the morning's tide, a vague attempt was made to catalogue the plants which crowd each other on the verge of salt water, and so to make comparison with that part of Australia the features of which provoked Adam Lindsay Gordon to frame an adhesive phrase concerning bright scentless blossoms and songless, bright birds.

Excluding the acacias and eucalypts, said to have given sameness to the scenes among which the exotic poet ranged, a long list might be compiled; nor will the pleasant sounds of the afternoon be set down in formal order to the vexing of his memory, for possibly he never heard the whoop and gurgle of the swamp pheasant or the blended voices of hundreds of nutmeg pigeons mellowed by half a mile of still, warm air.

Nor may such una.s.suming vegetation as the gra.s.ses--at least a dozen varieties--find place in an enumeration which appeals primarily on the grounds of prominence, though it would not do to despise the soft and pleasant carpet beneath the orderly row of Casuarinas which the tide planted during the last big cyclone with gardener's art. The common name for the trees--"she" (or "shea" oaks, as the late F. Manson Bailey preferred)--mimics the sound of the wind among the branches, which the slightest zephyr stirs and, the storm lashes into sea-like roar. The bright green of the gra.s.ses sets off the dull green and bronze of the steadfast harps of the beach. At certain seasons and in some lights, when the sun is in the west, the minute scales at the joints of the slender, pendulous branchlets shine like old gold, producing a theatrical effect which, if not experienced before, startles and almost persuades to the belief that the complaining trees have been decorated by one who "has sought out many inventions." But the slant of the sun alters, the light fades, leaving them sombre in hue and whispering more and more discreetly as the night calm settles over the scene. Such communicable trees should stand together, commenting on pa.s.sing events, booming in unison with the cyclone, and mimicking the tenderest tones of the idlest wind. During a storm, when the big waves crash on the beach and the Casuarinas are tormented, the tumult is bewildering; but however loud their plaint, very few suffer, though growing in loose sand; for the roots are widespread and, like the trunk and main branches, tough, while the branchlets stream before the wind.

Close behind the screen of Casuarinas is a magnificent specimen of a wide-spreading shrub, in form a squat dome, which commemorates the name of a French naturalist--TOURNEFORTIA ARGENTA. The leaves, crowded at the ends of thick branchlets, are covered with soft, silky hairs of a silvery cast, which reflect the sun's rays. It would be gross exaggeration to say that the finely shaped shrub shines like silver, for the general hue of the foliage is sage green, but that it has a silvery cast, which in certain lights contrasts with the dull gold of its neighbours, is an alluring fact which must not be strained. Moreover, the shrub covers an almost perfect circle, about thirty feet in diameter, and since it is not more than ten feet high, its form is as if Nature had designed the creation of a circus of shadow, dense and cool, for the comfort of mankind.

At high-water mark stands one of the Terminalias with big terminal light green leaves, musty flowers, and purple fruit--gold, silver, and purple in close array--while over the sand the goat-footed convolvulus sends long, succulent shoots bearing huge pink flowers complementary to the purple of the beach-pea (CANVALIA OBTUSIFOLIA).

Under the she-oaks young coral trees have sprung up, but the red flowers are of the past, and so also have the gold and white of the Calophyllums disappeared. But in the evening the breeze brings whiffs of a singular savour, pleasant yet not sweet, which comes from the acre or two of native hops a few yards back. The bruised leaves thereof give off anything but an attractive odour, yet the faint natural exhalations from the plant are sniffed eagerly and to the revivification of pleasant recollections.

Among a crowd of ma.s.sive shrubs sprawls a plant of loose habit known as CAESALPINA BONDUCELLA, the long clinging branches and the pods of which are armed with hooked p.r.i.c.kles. It is a plant of wide range, for the bluish-grey seeds are said to be used in Arabia for necklets. In the idle days of the past the blacks were wont to enclose a single seed in a miniature basket woven of strips of cane for the amus.e.m.e.nt of infants--probably the first of rattles. It has seized for support some of the branches of a rare tree (CERBERA ODOLLAM) which bears long, glossy, lanceolate leaves, large, pink-centred, white flowers, delicately fragrant, and compressed oval fruit, brilliantly scarlet. The tempting appearance of the fruit is all that may be said in its favour, for it is hard and bitter, and said to be vicious in its effects on the human system; hence the generic t.i.tle, after the three-headed dog, guardian of the portals of the infernal regions.

Grouped here and there are pale green, big-leaved shrubs (PREMNA OBTUSIFOLIA,) bearing flowers and fruit calling to mind the elder of the old country. The wood is deep yellow in colour, but apparently of no practical use.

Another small tree, suggesting in its regular and well-balanced shape the use of the pruning-knife, is GUETTARDIA SPECIOSA, the flowers of which are white with a tinge of pink in the centre and highly fragrant.

The fruit is a hard, woody drupe, containing small seeds. TIMONIUS RUMPHII, belonging to the same Family, but of more frequent occurrence, bears small white flowers and globular fruit. The white, finely grained wood is said to resemble English sycamore. Though harsh and flaky, the surface of the bark seems to retain moisture, making it attractive to several species of fungi and epiphytal ferns, the most conspicuous of the latter being the stag's-horn. Few of the trees near the beach are free from such enc.u.mbrances.

To unaccustomed eyes the Panda.n.u.s palm is chief among the noticeable features of the flora of the coast of tropical Queensland. Two species are represented on these accommodating sands, each suffering no ill, from imbibing salt water, each exhibiting the peculiarity whence the genus derives its common name--the screw palm, the arrangement of the long, narrow, p.r.i.c.kle-edged leaves displaying in the most regular and demonstrative style the perfect spiral. The single stem of youth frequently deteriorates and occasionally disappears altogether, advent.i.tious roots, descending from various heights, forming an elaborate and sure and ever-developing support. The huge, bright orange-tinted fruit of the species known as Odoratissimus is highly attractive in appearance, and to the uninitiated offers pleasing hopes and delicious expectations. It is, however, delusive, being const.i.tuted of woody drupes in close cl.u.s.ters collected into a globular head, with meagre yellow pulp at the base of each group, the pulp having an aromatic and unsatisfactory flavour. Each drupe contains an oblong oval kernel, pleasant to the taste, but so trivial in size as to be hardly worth the trouble of extraction unless there is little else to occupy attention save the pangs of hunger. These defects do not detract from the parade of the tree--picturesque, singular, and replete with interest to the observer of the infinite variety of the vegetation of the tropics.

The c.o.c.katoo apple (CAREYA AUSTRALIS), which has several useful qualities, flourishes exceedingly. The ripe fruit, green and insipid, was wont to be eaten by the blacks, bark from the branches was twisted into fishing-lines, that of the roots used for poisoning fish, while the leaves, heated over the fire until the oil exuded, were applied to bruised and aching parts of the body. Extraordinary tenacity of life distinguished the tree, the axe, fire, and poison failing under some circ.u.mstances to vanquish it.

Another and closely related member of the same Family (Myrtaceae) is BARRINGTONIA SPECIOSA, which, so far as local experience is to be trusted, is restricted to the beaches, growing l.u.s.tily in pure sand at the very verge of high-water mark. The glossy leaves of this many-branched tree often exceed a foot in length; the flowers, too, are large and singular in style, the petals being comparatively insignificant, while the numerous stamens attain a length of four inches and are of a lovely shade of red. Like its relative, the c.o.c.katoo apple, the flowers of the Barringtonia have a meaty smell, which seems to attract many species of insects. In keeping with other characteristics, the fruit is large, consisting of a thick, woody covering, as if Nature designed that the single seeds should be adequately protected during a protracted oceanic drift. It is often cast up on the sand, but the seed does not germinate as consistently as that of the cannon-ball-tree; but when it does it rarely fails to become established.

Two species of Ficus deserve to be mentioned, though this catalogue does not claim to be exhaustive. FICUS FASCICULATA, as the t.i.tle implies, bears its inedible fruit in bundles, branches, trunk, and exposed roots, being alike fertile, and is almost as retentive of life as the c.o.c.katoo apple. Opposita is remarkable for varied form of foliage, referred to particularly elsewhere, and for the sweetness of its fruit.

One of the loveliest and most remarkable plants of the beach is the seacoast laburnum (SOPHORA TOMENTOSA), with its pinnate leaves of sage green, h.o.a.ry with silvery fur as soft as seal-skin, and bearing terminal spikes of golden flowers with scent invoking slight comparison with mignonette. The thick, silky leaves, the yellow flowers, and the strange pods, are distinctive qualities, which atone for the absence of the special sweetness of the garden favourite. The pods begin as slender, silvery, dangling threads, which speedily lengthen and become constricted. When the breeze fl.u.s.ters the shrubs, revealing the undersides of the leaves at a reflective angle and shaking the ta.s.selled pods, and the splashes of gold sway hither and thither, the character of the shrub as one of the most attractive ornaments of the beach is so truly displayed that it might be likened to the tree of the sun described by Marco Polo--green on one side, but white when perceived on the other.

This quality, however, is not special or peculiar. The brown kurrajong (COMMERSONIA ECHINATA) exhibits it even more conspicuously, and, when the dusty white flowers--displayed in almost horizontal planes--are buffeted by the winds and the white undersides of the leaves are revealed, the whole style of the tree is transformed as a demure damsel is by tempestuous petticoats.

With the grey-green of the Sophora is often intertwined the leafless creeper Ca.s.sYTHA FILIFORMIS, which in the days of the past the blacks were wont to use with other beach plants in the composition of a crude seine net. The long-reaching, white-flowered CLERODENDRON INERME and the tough, sprawling BLAINVILLEA LATIFOLIA, with its small, harsh flowers, yellow as b.u.t.tercups but resembling a daisy in form, were also embodied in the net.

The Poonga oil-tree, the new and old leaves the colour of new copper, and the mature the darkest of green, bears spikes of pale lavender flowers, and makes a decided blotch among the light green succulent leaves of the native cabbage (SCAEVOLA KOENIGII), with its strange white flowers and milk-white fruit. All parts of the plant are said to be emetic.

Two varieties of VITEX TRIFOLIA, each bearing pretty lavender flowers, but in other respects sharply contrasted, are among the commonest of denizens of the beach. The one is a prostrate plant with sage-coloured and sage-scented leaves; the other a shrub or small tree with light green foliage, the underside of which is mealy-white, and flowers paler than those of its lowly kin. Each is pretty, and the creeping variety (known in Egypt as the "Hand of Mary") decidedly one of the most eager lovers of the sand, to which it keeps strictly.

Almost within reach from high water are representatives of a tall, shining-leaved shrub known as MORINDA CITRIFOLIA, the flower-heads of which merge into a berry which has a most disagreeable odour and a still more objectionable flavour. It is related that when La Perouse was cast away on one of the islands of the South Pacific, a native undertook to ward off the pangs of hunger by converting the fruit into an edible dish. But his manipulation seemed but to intensify original nauseousness, and the brave Frenchman and his companions found semi-starvation more endurable than the repugnant mess.

Magnificent representatives of the umbrella-tree (BRa.s.sAIA ACTINOPHYLLA), unique among the many novelties of the tropical coast, are ma.s.sed in groups or stand in solitary grace close to the sea.

Queensland has a monopoly over this handsome and remarkable tree, the genus to which it belongs being limited to a single species occurring nowhere else in a native state. Discovered by Banks and Solander at Cooktown in 1770, the second record of its existence, it is believed, was made from specimens obtained on this island by Macgillivray and Huxley in 1848. Possibly the very trees which attracted their attention still crown their rayed and glossy leaflets with long, radiating rods thickly set with red, stud-like flowers. Such foliage and such flowers would appeal gloriously to an enthusiastic botanist, and to so devoted, indefatigable, and successful a searcher after the wonders and the higher truths of the world as Huxley.

Few of the ornaments of the beach are more noticeable than that known commonly as the sunflower-tree and by the natives as Gingee (DIPLANTHERA TETRAPHYLLA), with its big leaves, soft of surface when young, but harsh and coa.r.s.e at maturity. The golden flowers, grouped in huge heads, are rich in nectar, attracting birds and b.u.t.terflies by day and flying foxes at night. The fruit, enclosed in a crisp capsule, is tough and leathery, in shape a flattened oval, and is entirely covered with silken seeds lying close and dense as the feathers of the grebe. When numbers of the capsules open simultaneously, the seeds float earthwards like a silvery mantle or stream before the wind like a veil. Rarely the capsule falls to the ground complete, and then the parting of the valves reveals the fruit, in form not unlike a small fish covered with glistening scales.

The soft white wood is generally condemned, but duly seasoned it becomes tough, and is durable when not exposed to the weather. Like other quick-growing trees, the Gin-gee takes no long time in arriving at maturity, and its life is comparatively brief. Often big trees die from no apparent cause, and the wood becoming dry and tindery, the limbs crash to the ground suddenly, and in a few months the whole substance disappears in dust and mould.

Though the flowering season of the Calophyllum is of the past, the tree which bestows on the beaches the deepest shade and is handsome in all its parts must not be disregarded, for does it not, ever and anon, strive after a higher purpose than the production of goodly leaves, white flowers, and nuts "harsh and crude"? On rare occasions the external covering of the nut turns yellow on the tree, and is then found to enclose a thin envelope of pulp of aromatic and rather gratifying flavour. Such a phenomenon seems to manifest inherent excellencies, a laudable effort towards self-improvement, a plea for a.s.sistance on the part of some approving and patient man, an indication of the lines on which he might co-operate. The tree does not need gloss for its perfect leaves or fragrance for its flowers, nor need the qualities of its pink wood of wavering figure be extolled. With the exception of the stamens, all parts of the inflorescence, inclusive of the long pedicles, are milk-white, and the perfume is as sweet and refreshing as an English spring posy. Chemists tell us that the oil from the kernels contains a green pigment which changes to yellow on saponification, and that the resin is emetic and purgative, and healing when applied as plaster.

If botanical science can develop the meritorious tendencies the fruit occasionally exhibits, the Calophyllum would certainly rank as one of the most wonderful of all tropical fruits. And may it not be wise to indulge the highest hopes when it is borne in mind that at the head of the Family to which the Calophyllum belongs stands that queen of fruits--the mangosteen? Faith in the probable idealisation of the Calophyllum is justified by reference to the "Prefatory and Other Notes"

to the late F. M. Bailey's great work, the "Comprehensive Catalogue of Queensland Plants," where is to be found these encouraging words: "When any particular plant is said to furnish a useful fruit, it must not be imagined that the fruit equals the apple, pear, or peach of the present day, but all so marked are superior to the fruits known to our far-back forefathers."

Two eucalypts--bloodwood and Moreton Bay ash (CORYMBOSA and TESSELLARIS respectively)--and two acacias are represented, the former developing into great trees of economic value, the latter being comparatively short-lived and ornamental. The young shoots of Acacia flavescens are covered as with golden fleece, and its globular flowers are pale yellow.

The wood resembles in tint and texture its ally, the raspberry-jam wood of Western Australia, though lacking its significant and remarkable aroma. ACACIA AULACOCARPA displays in pendant ma.s.ses golden ta.s.sels rich in fragrance.

The yellow-flowered hibiscus (cotton-tree) overhangs the tide, and the small-leaved shrub the blacks name Tee-bee (WIKSTRAEMIA INDICA), the pink, semi-transparent fruit of which is eaten in times of stress, springs from pure sand.

A tall, almost branchless shrub (MACARANGA TANARIUS), the Toogantoogan of the natives, grows in close clumps conducive to the production of light, straight, slim stems used as fish-spears. The bark peels readily in long strands, easily convertible into lines, and the sap from incised stems, which crystallises with a reddish tint, is a fast cement. Huge platter-shaped leaves are supported on long stalks from nearly the centre, whence radiate prominent nerves of pale green. Some plants exhibit leaf-stalks of ruby red, with central leaf-spot and nerves like in hue, producing the most beautiful effect. If the growth of the plant could be kept within bounds it would be gladly admitted as a garden shrub. The stems and the base of the leaf-stalk are coated with, glaucous bloom, like that of a ripe plum. The bloom, easily to be rubbed off, is said to derive its t.i.tle from that Glaucus who took part in the Trojan War and had the simplicity, or the wisdom, to exchange his suit of golden armour for one of iron.

The length of the beach thus casually examined is not more than a quarter of a mile long, and no plant mentioned is more than a few yards from high-water mark, the soil being almost pure sand. Imagine some three square miles of country varied by hills and flats of rich soil, with creeks and ravines, precipices and bluffs, dense jungle and thick forest, hollows wherein water lodges in the wet season, and granite ridges, and then endeavour to comprehend the botany of one small island of the tropical coast!

To obtain demonstration of the vitalising and nourishing principles in maritime sands under the effects of heat, light, and moisture, it is necessary to retrace our steps and walk round the sandspit to the transfigured and degenerate mouth of that once mangrove-creek known to the blacks by a name signifying that a boy once tethered in it a sucking fish (Remora). Obstructed by a bank, the creek is dead and dry save when the floods of the wet season co-operate with high tides and effect a breach, to be repaired on the cessation of the rains. No more than four years have pa.s.sed since the formation of the bank began. It is now a shrubbery made by the incessant and tireless sea from materials hostile, insipid, and loose-sand, sh.e.l.ls, and coral debris, with pumice from some far-away volcano. On this newly made, restricted strip one may peep and botanise without restraint, discovering that though it does not offer conditions at all favourable to the retention of moisture, plants of varied character crowd each other for s.p.a.ce and flourish as if drawing nutriment from rich loam.

Several botanical Families are represented, the genera and species being:

Casuarina equisetifolia (she-oak) Avicennia officinalis (white mangrove).

Clerodendron inerme.

Premna obtusifolia.

Vitex trifolia.

Vitex trifolia, var. obovata.
