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” pronounced 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 titles 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, coarsely bundle them together, and, wading into an enclosed pool where fish are observed, beat the mass (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 title 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 fictitious and fugitive charms to quite commonplace but passive 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 scraped 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 classes 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 class, the black boy generally fishes on an empty stomach, and his demeanour coincides. No slobbering 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.
