CHAPTER IV



GARDEN OF CORAL

Brammo Bay has its garden of coral--a border of pretty, quaint and varied growth springing up along the verge of deep water. It is not as it used to be--no less lovely than a flower-garden of the land. Terrestrial storms work as much if not greater havoc in the shallow places of the sea as on the land. Pearl-shell divers assert that ordinary "rough weather" is imperceptible at a depth of two fathoms; while ten fathoms are generally accepted as the extreme limit of wave action, however violent the surface commotion. Yet in the shallow sea, within the Barrier Reef in times of storm and stress, not only are groves of marine plants torn and wrenched up, but huge lumps of coral rock are shattered or thrown bodily out of place and piled up on "uproarious beaches."

A storm in March, 1903, which did scarcely any damage to vegetation ashore, destroyed most of the fantastic forms which made the coral garden enchanting. In its commotion, too, the sea lost its purity. The sediment and ooze of decades were churned up, and, as the agitation ceased, were precipitated--a brown furry, slimy mud, all over the garden--smothering the industrious polyps to whom all its prettiness was due. Order is being restored, fresh and vigorous shoots sprouting up from the fulvid basis; but it may be many years before the damage is wholly repaired and the original beauty of the garden restored, for the "growth" of coral--the skeletons of the polyps--is methodical and very slow. We speak of coral as if it were a plant, yet the reproduction is by means of eggs, and the polyp is as much an animal as a horse or an elephant.

In times past the marine garden comprised several acres in which were plants of almost every conceivable shape and form, and more or less bright and delicate in colour. Fancy may feign shrubs, standard and clipped; elaborate bouquets, bunches of grapes, compact cauliflowers, frail red fans. Rounded, skull-like protuberances with the convolutions of the brain exposed, stag-horns, whip-thongs yards long, masses of pink and white resembling fanciful confectionery, intricate lace-work in the deepest indigo blue, have their appointed places. Some of the spreading plant-like growths are snow-white, tipped with mauve, lemon-coloured tipped with white, white tipped with lemon and pale blue.

On the rocks rest stalkless mushrooms, gills uppermost, which blossom as pom-pom chrysanthemums; rough nodules, boat- and canoe-shaped dishes of coral. Adhering to the rocks are thin, flaky, brittle growths resembling vine-leaves, brown and golden-yellow; goblets and cups, tiered epergnes, distorted saucers, eccentric vases, crazily-shaped dishes. Clams and cowries and other molluscs people the cracks and crevices of coral blocks, and congregate beneath detached masses and loose stones. In these fervid and fecund waters life is real, life is earnest. Here, are elaborately armoured crayfish (PALINURUS ORNATUS), upon which the most gaudy colours are lavished; grotesque crabs, fish brilliant in hue as humming-birds. Life, darting and dashing, active and alert, crawling and slithering, slow and stationary, swarms in these marine groves.

A coral reef is gorged with a population of varied elements viciously disposed towards each other. It is one of Nature's most cruel battlefields, for it is the brood of the sea that "plots mutual slaughter, hungering to live." Molluscs are murderers and the most shameless of cannibals. No creature at all conspicuous is safe, unless it is agile and alert, or of horrific aspect, or endowed with giant's strength, or is encased in armour. A perfectly inoffensive crab, incapable of inflicting injury to anything save creatures of almost microscopic dimensions, assumes the style and demeanour of a ferocious monster, ready at a moment's notice to cry havoc, and let loose the dogs of war. Another hides itself as a rugged nodule of moss-covered stone; its limbs so artfully stowed away that detection would be impossible did it not occasionally betray itself by a stealthy movement. The pretty cowrie, lemon-coloured and grey and brown, throws over its shining shoulders a shawl of the hue of the rock on which it crawls about, grey or brown or tawny, with white specks and dots which make for invisibility--a thin filmy shawl of exquisite sensitiveness. Touch it ever so lightly, and the helpless creature, discerning that its disguise has been penetrated, withdraws it, folding it into its shell, and closes its door against expected attack. It may feebly fall off the rock, and simulating a dead and empty shell, lie motionless until danger is past. Then again it will drape itself in its garment of invisibility and slide cautiously along in search of its prey. Under the loose rocks and detached lumps of coral for one live there will be scores of dead shells. The whole field is strewn with the relics of perpetual conflict, resolving and being resolved into original elements. We talk of the strenuous life of men in cities. Go to a coral reef and see what the struggle for existence really means. The very bulwarks of limestone are honeycombed by tunnelling shells. A glossy black, torpedo-shaped creature cuts a tomb for itself in the hard lime. Though it may burrow inches deep with no readily visible inlet, cutting and grinding its cavity as it develops in size and strength, yet it is not safe. Fate follows in insignificant guise, drills a tiny hole through its shell, and the toilsomely excavated refuge becomes a sepulchre. Even in the fastness of the coral "that grim sergeant death is strict in his arrest." All is strife--war to the death. If eternal vigilance is the price of liberty among men, what quality shall avert destruction where insatiable cannibalism is the rule. There is but one creature that seems to make use of the debris of the battlefield--the hermit crab (CAENOBITA), which but half armoured must to avert extermination fit itself into an empty shell, discarding as it grows each narrow habitation for a size larger. Disconsolate is the condition of the hermit crab who has outgrown his quarters, or has been enticed from them or "drawn" by a cousin stronger than he, or who has had the fortune to be ejected without dismemberment. The full face of the red blue-spotted variety (PAGURUS PUNCTULATUS) is an effective menace to any ordinary foe, and that honourable part is presented at the front door when the tenant is at home. For safety's sake the flabby gelatinous, inert rear end must be tucked and hooked into the convolutions of the shell, deprived of which he is at the mercy of foes very much his inferior in fighting weight and truculent appearance. The disinterested spectator may smile at the vain, yet frantically serious efforts of the hermit to coax his flabby rear into a shell obviously a flattering misfit. But it is not a smiling matter to him. Not until he has exhausted a programme of ingenious attitudes and comic contortions is the attempt to stow away a No. 8 tail into a No. 5 shell abandoned. When a shell of respectable dimensions is presented, and the grateful hermit backs in, settles comfortably, arrays all his weapons against intruders, and peers out with an expression of ferocious content, smiles may come, and will be out of place only when the aches of still increasing bulk force him to hustle again for still more commodious lodgings.

A frilled clam (TRIDACNA COMPRESSA) in its infancy seals or anchors itself in a tiny crack or crevice, and apparently by a continuous but imperceptible movement analogous to elbow-rooming, deepens and enlarges its cavity as it develops. Should it survive in defiance of all its foes, just taking from the sea the sustenance for which it craves with gaping valves, it may increase in bulk, but its apartment in the limestone never seems too large--just a neat fit In its abiding-place it presents an irregular strip of silk, green as polished malachite, or dark green and grey, or blue and slaty green, mottled and marbled, with crimped edges and graceful folds--an attractive ornament in the drab rock. Touch any part--there is a slow suspensory withdrawal, and then a snap and spurt of water as the last remnant of the living mantle disappears between the interlocking valves of porcelain white.

Apart from the bulk and the fantastic shapes of coral structures, there is the beauty of the living polyps. That which when dry may have the superficial appearance of stone plentifully pitted--a heavy dull mass--blossoms with wondrous gaiety as the revivifying water covers it. The time to admire these frail marine flowers is on an absolutely calm day. All the sediment of the sea has been precipitated. The water is as transparent as rock crystal, but like that mineral slightly distorts the object unless the view is absolutely vertical. It is a lens perfect in its limpidity. Here is a buff-coloured block roughly in the shape of a mushroom with a flat top, irregular edges, and a bulbous stalk. Rich brown alga hangs from its edges in frills and flounces. Little cones stud its surface, each of which is the home of a living, star-like flower, a flower which has the power of displaying and withdrawing itself, and of waving its fringed rays. Each flower is self-coloured, and may represent a group of animals. There are blues of various depths and shades from cobalt to lavender, reds, orange and pinks, greens, browns and greys, each springing from a separate receptacle. All are alike in shape--viewed vertically, many-rayed stars; horizontally, fir-trees faultlessly symmetrical in form and proportion. These flowers all blossom, or trees, or stars, are shy and timorous. A splash and they shrink away. The hope of such wilderness--as barren-looking as desert sandstone--ever blossoming again seems forbidden. Quietude for a few moments, and one after another the flowers emerge, at first furtively but gathering courage in full vanity, until the buff rock becomes as radiant as a garden bed.

Upon coral blocks, which represent the skeletons of polyps in orderly and systematic profusion, other creatures more highly organised appear, having in one feature a family likeness to the polyps, upon whose hospitality they impose, that is, if the setting up of an establishment on the remains of innumerable ancestors of its host may be said to be merely an imposition. One is a species of mollusc which resembles, in some respects, that to which has been given the name of SURPULA. In its babyhood it attaches itself to the coral, and forthwith begins to build a home, which is nothing more than a calcareous tube, superficially resembling a corpulent worm, instantaneously petrified while in the act of a more or less elaborate wriggle or fantastic contortion. In this complicated tunnel the creature resides, presenting a lovely circular disc of glowing pink as its front door. A few inches beneath the water this operculum or lid is not unlike a pearl, but as you gaze upon it, it slips on one side, and five animated red rays appear, waving like automatic flag signals. Though well housed, it is almost as timorous as the coral polyps. Upon the least alarm the rays disappear in a twinkle, and the pink pearl trap-door glows again. Break off the end of the shelly tunnel in an attempt to secure the pearl, and it is as elusive as a sunbeam. It recedes as piece by piece is broken away, until the edge of the cylinder is flush with the surface of the coral in which the shell is embedded. There the pearly operculum glows in safety.

The living rays or flower-like face are the features in which this encased worm resembles the coral polyps on the one hand and the houseless beche-de-mer on the other. Some of the
