Tropic Days, Edmund James Banfield [best thriller books to read .TXT] 📗

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 (BRASSAIA ACTINOPHYLLA), unique among the many novelties of the tropical coast, are massed 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 coarse at maturity. The golden flowers, grouped in huge heads, are rich in nectar, attracting birds and butterflies 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 assistance 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 masses golden tassels 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 title 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 passed 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, shells, 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 space 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. Carapa moluccensis (cannon-ball-tree). Erylhrina indica (coral-tree). Sophora tomentosa (sea-coast laburnum). Pongamia glabra (poonga oil-tree). Vigna luteola (yellow-flowered pea). Calophyllum inophyllum (Alexandrian laurel). Terminalia melanocarpa. Ximenia americana (yellow plum). Scoevola koenigii (native cabbage). Hibiscus tiliaceus (cotton-tree). Wikstroemia indica. Macaranga tanarius. Euphorbia eremophilla (caustic bush). Dodonaea viscosa (hop-bush). Passiflora foetida (stinking passion fruit). Ipomea pes caprae (goat-footed convolvulus). Ionidium suffruticosum, Form A. Ionidium suffruticosum, Form B (spade-flower). Blainvillea latifolia. Gnaphalium luteo-album (flannel-leaf or cud-weed). Vernonia cinerea (erect, fluffy-seeded weed). Remirea maritima (spiky sand-binder). Cyperus decompositus (giant sedge). Erigeron linifolius (cobbler's pegs or rag-weed). Tribulus terrestris (caltrops). Triumfetta procumbens (burr). Salsola kali (prickly salt-wort). Mesembryanthemum aequilaterale (pig's face). Anthistria ciliata (kangaroo-grass). Paspalum distichum (water couch-grass). Zoysia pungens (coast couch-grass). Lepturus repens (creeping wire-grass). Panicum leucophaeum (pasture-grass). Andropogon refractus (barbed wire-grass). Tragus racemosus (burr-grass). Eragrostis brownii, var. pubescens (love-grass).

With the exception of some of the grasses and two noxious weeds, this assemblage is representative of plants which grow just beyond the sweep of the waves, and are prosperously at home nowhere else. One, the cannonball-tree, is so highly specialised that its presence is but temporary, for it endures but a single set of conditions--saline mud and the shade of mangroves. The thick, leathery capsule contains several irregularly shaped seeds, somewhat similar to Brazil nuts, but larger in size and not to be reassembled readily after separation. When stranded, germination is prompt, but the young plants, lacking essential conditions, invariably perish. One of the trailers--the caltrops--has trilobed, saw-edged leaves (harsh on both sides), yellow flowers of unpleasant odour, and fruit which, perhaps, formed the model of the war weapon of the time of the Crusaders. In whatever position it rests on the ground it presents an array of spikes to the bare foot. Though all its superficial qualities are graceless, it performs the admirable office of binding sand, and thus prepares the way for benign and faultless vegetation.

That his garden might not only be instructive but profitable to mankind, Neptune heaved on to its verge three coco-nuts, the goose-barnacles on two of which bore testimony to a long drift. That which retained the germ of life fell into the hands of a visiting black boy, who split it open to feast on the pithy and insipid "apple" within its shell at the base of the sprout. This mischance ruined for the time being the prospect of a fine effect; but the perseverance and prodigality of Neptune none may estimate. He will certainly bring from distant domain another nut which may escape the observation of the never-to-be-satisfied black boys until the young plant itself has assimilated its concentrated food, and begins to spread its glossy fronds in the face of the sun. In the meantime the garden displays four weeds, two of the nature of pests, two of discomfort merely; ornamental, scented, and flowering shrubs, and trees promising to be conspicuous and picturesque, so that credit is to be divided--the sea made the site, the adjacent land provided all the becoming plants.

What are the elements in this primitive spot which afford nutriment to vegetation of such varied character? Probably there are few of the beaches of islands within the Great Barrier Reef on which the majority of the plants do not exist. It is typical, therefore, not of isolated experiments on the part of Nature, but of conditions and processes repeated in similitude wheresoever in the region raw sand heals the wounds inflicted by the sea or the grumbling sea retreats before the sibilant, incessant sand.
