Tropic Days Part 13

It, too, realised the futility of kicking against so many p.r.i.c.ks. On the other hand, Tom, with his heavy shaft and barbed point, relied on a single weapon. It seldom failed, for his right arm was strong and disciplined to a nicety.

On a shallow tidal creek a settler had made a corduroy crossing of the fibrous trunks of the Panda.n.u.s palms, which the blacks of the neighbourhood turned to account in the capture of fish. A few frail sticks, artlessly interwoven with gra.s.s, formed a primitive weir at the down-stream end of the crossing. Fish which went up with the tide frequently found themselves stranded on the way down, for the water pa.s.sed freely between the palm-tree trunks without affording them right of way, and the rude weir often stopped for ever belated bream, mullet, and barramundi. This simple trap, though it does not appear to be put into use on the coast generally, seems almost to indicate an instinctive knowledge of a studied design described to me by an observant friend who has travelled into many an odd nook and corner of Queensland. On a deep but narrow tributary of the Georgina River a permanent trap on a large scale was wont to be maintained. A tree had been felled across the stream so that each end of the trunk was supported by the respective bank. Straight stakes were driven firmly into the bed of the creek as closely together as possible, the heads resting against the horizontal tree-trunk. This palisading formed the base of an embankment of packed gra.s.s and rubbish, sufficiently tight to raise the level of the stream about three feet. In the middle of the embankment, and about one foot below water-level, a hole about one foot square had been cut. A platform about ten feet long by three feet wide, having a fall of about one foot and formed of a number of straight saplings laid parallel with the stream, and supported by a couple of transverse bearers on four stout forked sticks, received the escape from the sluice. At the lower end of the platform was a rough weir of twisted gra.s.s, which was continued up each side for about half its length. Water pa.s.sed with little hindrance through the platform, while jew-fish, yellow-tail, and bream, were retained in considerable numbers.

Many years have elapsed--peradventure centuries--since the blacks of Missionary Bay, Hinchinbrook Island, built a weir of blocks and boulders of granite which oysters cemented here and there. On the fulness of spring tides fish frolicked over and among the boulders. Those which delayed their exit found themselves in an enclosed pool which at certain seasons of the year runs dry. To this day the sea continues to pay tribute, though the blacks of the locality have pa.s.sed away, and there is none but the red-backed sea-eagle or the heavy-flighted osprey and a rare and casual white man, to receive it. Among the few emblems of the vanishing race, this persistent weir-taking toll of the fish month after month, year after Year, for the benefit of successive generations of eagles and ospreys, appeals vividly to the imagination.

HOOKS.

From what can be ascertained at this late date, pearl sh.e.l.l hooks were very sure and killing, but seem to have been used princ.i.p.ally for smaller fish--whiting, perch, bream, flathead, etc.--the occurrence of large hooks being exceedingly rare. Mullet (if tradition is to be credited) were seldom caught by hook and line, but were speared among the mangroves at high tide--a practice which prevails to this day.

The Dunk Island examples have a resemblance to one of the forms of pearl-sh.e.l.l hooks used by the Tahitians in Captain Cook's day.

Tortoise-sh.e.l.l hooks capable of holding large kingfish and fair sized sharks are common among the natives of Darnley Island, Torres Straits.

During the process of cutting and paring the hooks to the size and design required, the sh.e.l.l is frequently immersed in boiling water, which temporarily overcomes its inherent toughness. Incidentally, it may be pointed out that the evidence derivable from these fish-hooks does not afford proof of Papuan influence on the mind of the Australian aboriginal, except at the extreme north of Cape York Peninsula and a few miles down the eastern coast of the Gulf of Carpentaria. This default seems the more remarkable in face of the fact that outrigger canoes, doubtless of Papuan or Malayan origin, were known as far south as the Johnstone River.

To say that the coastal blacks of North Queensland had no knowledge of the use of barbed hooks is misleading. In sheer desperation, when the supply of pearl-sh.e.l.l hooks was exhausted, they were wont to attach bait to their harpoon-points, and they used such unpropitious means successfully, and occasionally made a miniature hook by tying a sharp spur to a thin, straight stick. Recent proof has been obtained of the use of the lorum of one of the creeping palms, from which all the spurs save three at the thicker end were sc.r.a.ped off. With the knowledge of the efficacy of the barb under extraordinary circ.u.mstances, is it not the more remarkable that they failed to employ it systematically? Dr.

W. E. Roth describes crescentic hooks of coco-nut sh.e.l.l and wooden hooks with bone barb, and also barbs improvised from one of the spines of the catfish. He also mentions as "the most primitive form of hook" the dried tendril of HUGONIA JENKENSII ("pattel-pattel" of the Dunk Island blacks). To anyone familiar with the crescent pearl-sh.e.l.l hooks, the use of the singular tendrils of the Hugonia would immediately be suggested; but my observation, inquiries, and opinion do not support the theory.

The shape of the tendril is all that can be said in its favour. It is neither sharp nor tough enough for actual use.

With these barbless hooks the bait was not impaled, but strapped on with shreds of bark.

NARCOTICS AND POISONS.

It is said of the great Mogul Emperor Babur that he boasted of being able to make fish drunk so that he might haul them in shoals, and when "Carathis" p.r.o.nounced her "barbarous incantations" the fish with one accord thrust forth their heads from the water. Is it generally known that the North Queensland blacks also are expert in the use of narcotics and indifferent to the ethics of sport? The most commonly used of the fish poisons on the coast of North Queensland is likewise employed by the natives of Zambesi Land for a similar purpose. The plant is known botanically as "Derris." Two varieties, "scandens" and "uligijiosa," are known in this State. The aboriginal t.i.tles vary in different localities, but "Paggarra" will suit the present purpose. Some blacks are so offensively civilised that they know the plant by the name of "Wild Dynamite." Possibly it owes its popularity among fish poisons to the fact that it is the handiest of all. It trails over the rocks, just out of touch of high-water mark, but not beyond the reach of the spray of surges. With roots investigating inclement crevices, and salt air damping its leaves, the plant flourishes, and flowers prettily in graceful racemes. In the semi-obscurity of the crevices the flowers put on a tinge of pink, literally blushing unseen. The heartless blacks tear up the plant, branches, leaves, flowers and all, coa.r.s.ely bundle them together, and, wading into an enclosed pool where fish are observed, beat the ma.s.s (after dipping it into the water and while held in the left hand) with a nulla-nulla. The action is repeated until the bark and leaves are macerated, and then the bundle is thrown into the pool. In a few minutes the fish rise to the surface, gasping and making extraordinary efforts to get out of the infected water. Death ensues rapidly, but the fish are quite wholesome as food.

Another of the vegetable poisons is known as "Raroo" (CAREYA AUSTRALIS).

The bark at the base of the trunk and of the roots contains an effective principle, which is released in a somewhat similar fashion to that employed with "Paggarra."

The fruit of the handsome, shrubby tree known botanically as DIOSPYROS HEBECARPA is also a most effective fish poison. It is oval-shaped, red when ripe, and, as the name implies, covered with soft, fine hair. For all its lofty t.i.tle and attractive appearance, the fruit is deceptive, for it bites and blisters the lips and tongue like caustic, and on being bruised and thrown into a pool on the reef, all fish are killed outright.

A different and, for a black, singularly complicated process is employed for the extraction of the noxious principle residing in the plant known as "Koie-yan" (FARADAYA SPLENDIDA). This is one of the most rampant and ambitious of the many vines of the jungle.

It combines exceeding vigour with rare gracefulness. The leaves are a light glossy green, ovate, and often a foot long, while the flowers are pure white (resembling slightly the azalea, but free from its fragility), large, and with an elusive scent, sweet and yet indefinite.

The fruit, smooth and of porcelain whiteness, varies in size and shape, and is said to be edible, though blacks ignore it. A large marble and an undersized hen's egg may dangle together, or in company with others, from the topmost branches of some tall tree, which has acted as host to the clinging vine. The handsome but inconsiderate plant is turned from its purpose of lending fict.i.tious and fugitive charms to quite commonplace but pa.s.sive trees to the office of stupefying uncomplaining fish. But the element which holds such deadly enmity to the sense of the fish is not obtainable by the simple primary means successful with other plants. Indeed, the process is quite elaborate, and goes to prove that the Australian aboriginal has to his credit as a chemist the results of successful original research, and that he is also a herbalist from whom it is no condescension to learn. In this detail, at any rate, he is distinctly an accomplished person. Portions of the vine are cut into foot lengths; the outer layer of bark is removed and rejected, the middle layer alone being preserved. This is carefully sc.r.a.ped off and made up into shapely little piles on fresh green leaves. One might imagine that a black boy preparing the deadly "Koie-yan" was really playing at chemist's shop with neat-handed scrupulousness. When a sufficiency is obtained it is rubbed on to stones previously heated by fire. The stones then being thrown into a creek or a little lagoon left by the receding tide, the poison becomes disseminated, with fatal effect to all fish and other marine animals.

It is pointed out, however, by Dr. Hamlyn-Harris that the nature of the active principle of the "Koie yan" does not permit of elaboration by such means. The heating of the shredded bark would, therefore, appear to fall into line with the gibberish of ancient alchemists. It would bewilder the uninitiated without enhancing results.

Many other plants supply the means of killing small fish wholesale, or of reducing them to palsied cripples. The three described are fairly common, and have, therefore, been selected to point a moral. Poisoning fish is a poor sort of sport, perhaps, but there are two cla.s.ses of fishermen--the hungry and the artistic. The latter use flimsy tackle and complicated gear, and play the game, giving the victims to their wiles a sporting chance. Though not the only representative of the hungry cla.s.s, the black boy generally fishes on an empty stomach, and his demeanour coincides. No s...o...b..ring sentiment affects him. Yet he is not so cruel as the mean white who throws a plug of dynamite into the river while the fish are enjoying their crowded hour, though he will with as little taint upon his conscience poison a pool full of fish as drag with hooked stick a reluctant crab piecemeal from its burrow among the mangrove roots. But then he is responding to the appeals of a clamant and not over-particular stomach, while your dynamitard is occasionally a well-fed barbarian with a queasy palate.

FLY-FISHING.

The neatest and most artistic method by which the blacks kill fish necessitates the employment of a particular species of spider known to the learned as NEPHILA MACULATA PISCATORUM. This spider was discovered on Dunk Island by Macgillivray, the naturalist of the expedition of H.M.S. RATTLESNAKE in 1848. It has a large ovate abdomen of olive-green bespangled with golden dust; black thorax, with coral-red mandibles; and long, slender legs, glossy black, and tricked out at the joints with golden touches. A fine creature, gentle and stately in demeanour, it spins a large web, strong enough to hold the biggest of beetles and other insects, and, to harmonise with the superior air of the manufacturer, the gossamer is of golden-green. The great spider at the focus of the resplendent web is a frequent and conspicuous ornament to the edges of the jungle, and having no fear, and no indocility of temper, it undergoes the ordeal of admiration with an a.s.sumption of disdainful coquettism. The local name of this comely creature is "Karan-jamara." Shameless polyandrist, she maintains several consorts--from three to five seems to be the average number--and they, semi-transparent, feeble, meek, subdued little fellows, maintain precarious isolated existences in the outskirts of the web.

Though my own experience is negative, direct incontrovertible evidence is extant to the effect that birds often meet their fate by blundering into the web, to be devoured by the nimble and gaily decorated owner. I have frequently seen karan-jamara disposing of hard-sh.e.l.led beetles as big in bulk as some birds, and the strongest of b.u.t.terflies, once entangled, is powerless. The long-legged spider leaps on the struggling prey and stills its beating wings with one pinch of powerful red mandibles. March flies form the most frequent diet. One has been observed to dispose of fourteen of the great stupid flies in a single evening, and if the flies could reason they might, while whimpering because of the existence of such voracious spiders, acknowledge that they design their webs in a very perplexing and masterly manner.

In pursuance of inquiries--the results of which are herein recorded--a casual black boy, a stranger to these parts, and therefore unfamiliar with the local name and the special purpose to which the spider is put, was cross-examined. At first he failed to recognise the photograph, but when it was explained by the pointed allusion to a living Maltese-cross spider close at hand, a gleam of intelligence brightened his bewildered face, and he delivered a self-satisfied dissertation on the order Arachnida that is worth quoting:

"That fella Oo-boo-boo. That fella mammy belonga 'nother fella altogether. You no savee, come close up--that fella ply way. You no savee, come close up, that fella no good; that fella vite."

And the boy looked gravely sagacious and smiled the wide, wise smile betokening proud superiority of information. Had Macgillivray but known that the "Oo-boo-boo" was the parent of all the many species, and that it belongs to the discreetly valorous cla.s.s that "vites" and flies away, and lives to "vite" another day, he might have achieved renown of a more popular kind than is the reward of the unromantic naturalist who discovers merely a superior spider.

This spider is used on some of the rivers as a lure, virtues almost irresistible being ascribed to it. Experiments in salt water, though not absolutely negative in their results, have not afforded any specially exciting sport; but possibly the fascination of the lure is more efficient in fresh than in salt water, and is influential over the habitual caution throughout a certain species of fish only. The trick is worked in the following manner:

The angler takes a light, thin switch and entangles one end in the web, which, by dexterous waving action, is converted (without being touched with the fingers) into a strand about two feet long. The spider is secured and squashed, and the end of the line moistened in the juices of the body, some of the fragments of which are reserved for bait, and also to be thrown into the water as a preliminary charm. These buoyant t.i.tbits attract shoals of small fish, among which the line, with its extract of spider, is delicately trailed; a fish rises to the lure, the gossamer becomes entangled in its teeth, and it is landed by a brisk yet easy movement of the wrist. A great angler recently said that throwing a fly is an act of feeling or instinct rather than reason. So the black boy with a careless flourish fills his dilly-bag, while he smiles at the serious attempts of the white man to imitate his skill.

Owing to the brevity and the frailness of the line, the catch is limited to fish under the recognised standard as to size. Tests prove that the breaking strain of the line is nearly three-quarters of a pound, but the weight of the individual is of no great consideration, since numbers are caught quickly. The gossamer is singularly sticky. The viscid substance with which it is coated is not readily dissolvable in water; indeed, water seems to have the effect of hardening it, so that the line'

wears longer than might be expected. Piquant morsels of the spider are entangled in the frayed end of the line as its original potency becomes non-effective.

A friend for whose edification this novel method was demonstrated thus writes it:

"It did not take the boy long to get ready. They simply broke a switch about three feet long and attached a portion of the web about six inches long to the end; squeezed out on to a leaf the fluid internals of the spider, into which they dipped the end of the line, started a rather melodious chant, and put the line in shallow water. I was only a few feet away and could see no fish at first, but they came very soon. They were very small, about one and a half inches long. They fasten their teeth in the web, and are lifted out quite slowly. Some require to be pulled off the line after being landed. I watched for about ten minutes, during which time seventeen were caught."

Sir William Macgreggor, ex-Governor of Queensland, has described the Papuan art of fishing by means of kites, the lure being a ta.s.sel of the web of a spider of the Nephila species. No doubt the blacks here made an independent and original discovery, and in their simplicity applied it in a different, but none the less effective, style from that of the advanced Papuan.

Thus, to use the web and the fragments of a spider for fly-fishing is certainly meting out poetic justice to the spider on account of the many ensnared flies; and the black angler never pauses to reflect whether the comminuted remains of a spider can possibly be construed into a fair fly.

PART II--MISCELLANEA

PEARLS

WHAT IS A PEARL?

What is a pearl? The substance of a sensation--the consolidation of discomfort on the part of an oyster or other nacre-secreting mollusc. It is a globular deposit of carbonate of lime, with a very small proportion of water, generally enclosing a trifle which is its cause and core and, so to speak, is a waste product of the body's chemistry. In the restricted, scientific sense, "true pearls are bodies consisting of calcareous material with an organic basis." Similar bodies having cores of sand grains or other foreign substance are known as "blisters."

Science, which peers and probes into the innermost affairs of oysters, and speaks of them in terms of uneasy familiarity, a.s.serts that pearls are frequently caused by a parasite to which they are subject.

It would ill become one who has no scientific pretensions to suggest other definitions, though he may claim to be among the few who have been privileged to observe a pearl in the making, or, rather, to watch Nature's finishing touches.

In the case of the oyster the radical home cure for the living irritant or insoluble substance which had gained entrance between its valves is an encas.e.m.e.nt of pearl-film. If this encas.e.m.e.nt is globular or pear-shaped, or takes the form of a b.u.t.ton and is lucid, l.u.s.trous, flawless, and of large size, it may be of almost inestimable worth.

Does the proud beauty who glories in the possession of a pearl condescend to imagine that she flaunts on her bosom just so many tombs containing the dust of the germs of a parasite? Does she not rather love to think of the gems as emblems of almost celestial purity, and to dwell on the fable of the Persians rather than the audacious modern fact?

Addison has set the fable in imperishable gold: A drop of water fell out of a cloud into the sea, and finding herself lost in such immensity of fluid matter, broke out into the following reflection: "Alas! What an inconsiderable creature am I in this prodigious ocean of waters; my existence is of no concern to the universe; I am reduced to a kind of nothing, and am less than the least of the works of G.o.d." It so happened that an oyster which lay in the neighbourhood chanced to gape and swallow it up in the midst of this its humble soliloquy. The drop, says the fable, lay a great while hardening in the sh.e.l.l, until by degrees it was ripened into a pearl, which, falling into the hands of a diver after a long series of adventures, is at present that famous pearl which is affixed on the top of the Persian diadem.

Though one may count his pearls by the score, the h.o.a.rd may be valueless. Upon such examples entertaining, if not valuable, experiments may be made without affectation or giving hostages to fortune. In all the little deformed specimens thus dissected the core has been found to consist of a foreign substance, generally what seemed under a microscope of limited power a speck of dirt. The heart of one was a blob of mud, which gave off a most baleful vapour. This was the result of the house-cleaning of a common, edible rock oyster, and the pearl, dirty green and l.u.s.treless, merely a thin casket, for the noisome mud had not solidified. The care with which the impurity had been rendered innocuous demonstrated the correct ideas of the oyster on sanitation. No doubt the germ of the special form of tape-worm which troubles oysters, irritates to pearl-making, and pa.s.ses through other transformations in other hosts, and completes its cycle in the body of a shark, would be too minute for inexpert detection. The fact that molluscs do intern foreign and obnoxious substances is testimony to their decency and love of cleanliness, and so may the pearl be still accepted as the embodiment of purity. Though all its little soul be dirt, the pearl is pure, and but for the dirt or the germ of a filthy ailment it would not be pearl.
