The chick which the parent bird has hidden remains a puzzle. It moves not, it may not blink. Its crafty parent has so nibbled and frayed the edges of the decaying brown leaves among which it nestles that it has become absorbed in the scene. There is nothing to distinguish between the leaf-like feathers and the feather-like leaves. The instinct of the bird has blotted itself out. It is there, but invisible, and to be discovered only by the critical inspection of every inch of its environment. You have found it; but not for minutes after its instinct has warned it to possess its soul calmly and not to be afraid. So firm is its purpose that if inadvertently you put your foot on its tender body it would not move or utter cry. All its faculties are concentrated on impassiveness, and thus does Nature guard its weakest and most helpless offspring.
While you ponder on the wonderful faith of the tiny creature which suffers handling without resistance, the shred of bark, driven by the imperceptible zephyr, falls a few yards away, and in an agony of anxiety utters an imploring purr, or was it an imprecation? That half purr, half hiss has been the only sound of the episode. It is a warning to be gone and leave Nature to her secrets and silences.
A month's abstinence may not be a very severe penance for an island on which the rainfall averages 124 inches per year; but when vegetation suffers from the cruelty of four almost rainless months, promises and slights amount to something more than mere discourtesy. How genuine the thanksgiving to the soft skies after an incense-stimulating shower. Insects whirl in the sunshine. Among the pomelo-trees is a cyclone of scarcely visible things. Motes and specks of light dance in disorderly figures, to be detected as animated objects only by gauzy wings catching the light and reflecting it. Each insect, wakened but an hour ago by the warmth of the moist soil, in an abandonment of the moment, is a helioscope transmitting signals of pure pleasure. Drops still linger on myriads of leaves, and glitter on the glorious gold of the Chinese laburnum; the air is saturated with rich scents, and the frolicking crowd, invisible but for the oblique light, does not dream of disaster. Their crowded hour has attracted other eyes, appreciative in another sense. Masked wood-swallows, swiftlets, spangled drongos, leaden fly-eaters, barred-shouldered fly-eaters, hurry to the circus to desolate it with hungry swoops. The assemblage is noisy, for two or three drongos cannot meet without making a clatter on the subject of the moment. They cannot sing, but clink and jangle with as much intensity and individual satisfaction as if gifted with peerless note. It is the height of the season, and a newly matched pair, satisfied with an ample meal, sit side by side on a branch to tell of their love, and in language which, though it may lack tunefulness, has the outstanding quality of enthusiasm. But why waste clamorous love-notes on a world busy with breakfast? The sportful, tail-flicking dandy flits and alights so that he may address himself solely to his delighted and accepting spouse, peering into her reddish eyes the while, and in ecstasy proclaiming, in tones as loud and unmusical as her own, that life overflows with joy when mutual admiration surcharges the breast.
The noise stays a company of metallic starlings in headlong flight from the nest-laden tree in the forest to the many-fruited jungle. Though they most conscientiously search the fronds of coco-nut palms for insignificant grubs and caterpillars, starlings do not hawk for insects. Held up by the excitement—for by this time other birds have darted to the feast—the starlings alight among the plumes of the laburnum, interrogating in acidulous tones, their black, burnished, iridescent feathers and flame-hued eyes making a picture of rare vividness and beauty.
How thin becomes the throng! Last night's shower, the morning warmth of the soil, have brought forth a gush of life that wheels and sparkles in the sun and becomes bait for birds. Are droughts designed by Nature to test endurance on the part of animal and vegetable life? Leaves fall from evergreen trees almost as completely as from the deciduous, and even the jungle is thickly strewn, while every slight hollow is filled with brittle debris where usually leaves are limp with dampness and mould. The jungle has lost, too, its rich, moist odours. Whiffs of the pleasant earthy smell, telling of the decay of clean vegetable refuse, do issue in the early morning and after sundown; but while the sun is searching out all the privacies of the once dim area, the wholesome fragrance does not exist.
Drought proves that certain species of exotic plants are hardier than natives. Wattles suffer more than mangoes, and citrus fruits have powers of endurance equal to eucalyptus. Whence does the banana obtain the liquid which flows from severed stem and drips from the cut bunch? Dig into the soil and no trace of even dampness is there; but rather parched soil and unnatural warmth, almost heat. Heat and moisture are the elements which enable one of the most succulent of plants to bear a bunch of fruit luscious and refreshing, and when heat alone prevails, the wonder is that the whole patch of luxuriant greenness does not collapse and wither. But the broad leaves woo the cool night airs, and while the thin, harsh, tough foliage of the wattles becomes languid and droops and falls, the banana grove retains its verdancy, each plant a reservoir of sap.
A noteworthy feature of the botany of the coast of tropical Queensland is its alliance with the Malayan Archipelago and India. Most of the related plants do not occur in those parts closest to other equatorial regions in the geographical sense, but in localities in which climate and physical conditions are similar. Probably there are more affinities in the coastal strip of which this isle is typical than in all the rest of the continent of Australia. One prominent example may be mentioned-viz., “the marking-nut tree.” When the distinctiveness of the botany of the southern portions of Australia from that of the old country began to impress itself on the earliest settlers, the miscalled native cherry was the very first on the list of reversals. The good folks at home were told that the seeds of the Australian cherry “grow on the outside.” The fruit of the cashew or marking-nut tree betrays a similar feature in more pronounced fashion. The fruit is really the thickened, succulent stalk of the kidney-shaped nut. The tint of the fruit being attractive, unsophisticated children eat of it and earn scalded lips and swollen tongues, while their clothing is stained indelibly by the juice. Botanists know the handsome tree as SEMECARPUS AUSTRALIENSIS, but by the indignant parent of the child with tearful and distorted features and ruined raiment it is offensively called the “tar-tree,” and is subject to shrill denunciations. The fleshy stalk beneath the fruit is, however, quite wholesome either raw or cooked, but the oily pericarp contains a caustic principle actually poisonous, so that unwary children would of a certainty eat the worst part. The tree, which belongs to the same order as the mango, has a limited range, and there are those who would like to see it exterminated, forgetful that in other parts of the world the edible parts are enjoyed, and also that a valuable means to the identification of linen is manufactured from it. A tree that is ornamental, that provides dense shade, that bears pretty and strange fruit, an edible part, and provides an economic principle, is not to be condemned off-hand because of one blot on its character.
An Indian representative of the genera produces a nut which when roasted is highly relished, though dubiously known as the coffin-nail or promotion nut, but there is no reason to believe that it is specially indigestible unless eaten in immoderate quantity.
One of the many bewilderments of botany is that plants of one family exhibit characteristics and habits so divergent that the casual observer fails to recognise the least signs of relationship. Similar confusion arises in the case of plants of the same species producing foliage of varied form. One of the figs (FICUS OPPOSITA) displays such remarkable inconsistency that until reassured by many examples it is difficult to credit an undoubted fact. The typical leaf is oblong elliptical, while individual plants produce lanceolate leaves with two short lateral lobes, with many intermediate forms. As the plant develops, the abnormal forms tend to disappear, though mature plants occasionally retain them. There seems to exist correlation between foliage and fruit, for branches exhibiting leaves with never so slight a variation from the type are, according to local observation, invariably barren. The leaves, which, when young, are densely hairy on the underside, on maturity become so rough and coarse that they are used by the blacks as a substitute for sandpaper in the smoothing of weapons. The fruit is small, dark purple when ripe, sweet, but rough to the palate.
During the fulness of the wet season, a diminutive orchid, the roots, tuber, leaf, and flower of which may be easily covered by the glass of a lady's watch, springs upon exposed shoulders of the hills. So far it has not been recorded for any other part of Australia, or, indeed, the world. Science has bestowed upon it the title of CORYSANTHES FIMBRIATA, for it is all too retiring of disposition to demand of man a familiar name. Probably it may be quite common in similar localities, but its size, its brief periodicity, and inconspicuousness, contribute to make it, at present, one of the rarities of botany. Beneath a kidney-shaped leaf a tiny, solitary, hooded, purple flower shelters with becoming modesty, the art of concealment being so delicately employed that it seems to preserve its virginal purity. There is proof, however, that the flower does possess some “secret virtue,” for if the plant be immersed in glycerine the preservative takes the hue of the flower. Nature having ordained that the plants should be elusive, they appear in remote spots and unlikely situations with foothold among loose and gritty fragments of rock, and with cessation of the sustaining rains disappear, each having borne but a single leaf and produced but a solitary flower. The leaf does not seem to be attractive to insects, nor is the flower despoiled or the tuber interfered with. The first dry day sears the plants, and succeeding days shrivel them to dust and they vanish. What part in the great scheme of Nature does the humble flower fulfil? Or is it merely a lowly decoration, not designed to court the ardent gaze of the sun, but to brighten an otherwise bare space of Mother Earth with a spot of fugitive purple?
