The Confessions of a Beachcomber

by E. J. Banfield

Powerful as nutmeg pigeons are on the wing, some suffer lingering deaths in consequence of a singular characteristic of one of the trees of the jungle. Tall and graceful, with luxuriant glossy leaves, there is nothing uncanny about the tree. In style and appearance it is the very antithesis of "the upas-tree," upon which legendary lore cast unmerited responsibility. Yet in certain respects it would be vain to enter upon its defence. It is no myth. There is no exaggeration in the statement that the character of the Queensland tree is actually murderous, and that it counts its victims by the thousand every season. Of the great host it destroys, all save a few may be very small and very feeble, and from the human standpoint some of its death-dealing is perfectly justifiable if not laudable. Not often, locally, is a bird destroyed, but the fact that occasionally one has the ill-luck to fall foul of it and to perish miserably in consequence, places the tree in the catalogue of the remarkable. Neither spike nor poison is used nor any sensational means of destruction but nevertheless the tree is sure and implacable in its methods.

The seed-vessels of the Queensland Upas-tree, "Ahm-moo" of the blacks (PISONIA BRUNONIANA), which are produced on spreading leafless panicles, exude a remarkably viscid substance, approaching bird-lime in consistency and evil effect. Sad is the fate of any bird which, blundering in its flight, happens to strike against any of the many traps which the tree in unconscious malignity hangs out on every side. In such event the seed clings to the feathers, the wings become fixed to the sides, the hapless bird falls to the ground, and as it struggles heedlessly gathers more of the seeds, to which leaves and twigs adhere, until by aggregation it is enclosed in a mass of vegetable debris as firmly as a mummy in its cloths. Small birds as well as lusty pigeons, spiders and all manner of insects; flies, bees, beetles, moths and mosquitoes, as well as the seeds of other trees are ensnared. Spiders are frequently seen sharing the fate of the flies, fast to seeds in the humiliating posture in which Br'er Fox found Br'er Rabbit on the occasion of the interview with the Tar Baby.

Insectivorous plants am common enough in Australia; but the "Ahm-moo," tree does not appear to make use of the carcases of its victims, though it kills on an exceptionally extensive scale.

On some of the islands where the tree is plentiful numbers of pigeons meet a dreary fate every season. The maturity of the seeds coincides with the hatching out of the young, and inexperienced birds pay dearly for their inexperience. The natural glutin is produced while the slim, fluted, inch-long seeds are green, but its virtue remains even after the whole panicle has withered and has fallen. So tenacious is it and prompt, that should a panicle as it whirls downward touch the leaves of lower branches of the parent, or of any neighbouring tree, it sticks and becomes a pendant swaying trap in a new position. At first glance it is not easy to identify the tree to which the obnoxious feature belongs.

The seeds occasion even dogs considerable distress, and might easily be the cause of death to them. As the dog endeavours to remove them from his feet and sides with his teeth, his muzzle is fouled, and he very soon exhibits confusion and alarm, and rolling about in frenzied attempts to free himself, gathers more and more of the seeds and accumulated rubbish.

One is led to ponder upon the purpose of this provision—to endeavour, if possible, to find its justification. Insects lured by the sweetness of the exudation are callously entrapped, and why so? Do the seeds require the presence of animal matter to ensure germination? In that case the tree is indirectly carnivorous, and therefore decidedly entitled to recognition among the curiosities of the island. Is the glutin secreted to secure the wide dispersal of the seeds? If so, the object is largely self-defeated, for seeds by the hundred cling as they fall to the branches of the parent tree, and to those of its lowly neighbours. Certainly some proportion of the seeds which reach the ground must be borne hither and thither by the agency of that eternal scratcher, the scrub fowl. But even a bird of such immensely proportionate strength may be seriously troubled by them. A case in point may be cited. A dog retrieving a scrub fowl, which had fallen in the vicinity of an "Ahm-moo" tree, emerged with it entirely enveloped with the seeds and adhering rubbish, and itself almost helpless from a similar cause. In this happy chance the seeds were eventually widely distributed. If the glutin is provided to prevent birds consuming the kernels, then the object is perfectly served; otherwise no very satisfactory reason is apparent why the tree should be invested with the means of destroying even humble forms of life. Is this one of the "lost chords" in the harmony of nature?

THE CREEPING PALM

Perhaps the most impressive feature of the jungle—that which takes fast hold, clings most tenaciously, and leaves the most irritating remembrances—is what is known as the lawyer cane or vine (CALAMUS). It is a vegetable of tortuous ambitions, that defies you, that embarrasses with attention, arrests your progress, occasionally envelops you in a net work of bewildering, slender, and cruelly-armed tentacles, that everywhere bristles with points, that curves back on itself, and makes loops and wriggles; that springs from a thin, sprawling and helpless beginning, and develops into almost miraculous lengths, and ramifies and twists and turns in "verdurous glooms," ascends and descends, grovels in the moist earth and among mouldy leaves, clasps with aerial rootlets every possible support, and eventually clambers and climbs above the tallest tree, twirling its armed tentacles round airy nothings. It blossoms inconspicuously, and its fruit is as hard, tough and dry as an argument on torts. Ordinary mortals call it a vine. Botanists describe it as a prickly climbing palm, and no jungle is complete without it. There are several varieties of this interesting plant, all more or less of a grasping, clinging character, and each of vital importance in the republic of vegetation.

Sometimes when it is severed with a sharp knife there flows from the cane a fluid bright and limpid as a judge's summing up; occasionally it is all as dry as dust and as sneezy, and its prickly leaf sheathes the abode of that vexing insect which causes the scrub itch.

This plant produces lengths of cane similar in every respect to the schoolmaster's weapon—familiar but immortal—varying in diameter from a quarter of an inch to an inch and a half, and in length, as some assert, to no less than 500 and 600 feet. Certainly 300 feet is not uncommon, and one can readily concede an additional 100 feet, knowing the extravagance of the remarkable palm under ordinary circumstances. And the cane weaves and entangles the jungle, binds and links mighty trees together, and with the co-operation of other clinging, and creeping, and trailing plants—some massive as ship's cables, and some thin and fine as fishing-lines—forms compact masses of vegetation to penetrate which tracks must be cut yard by yard. When this disorderly conglomeration of trees and saplings, vines, creepers, trailers and crawlers, complicated and confused, has to be cleared, as civilisation demands the use of the soil, sometimes a considerable area will remain upright, although every connection with Mother Earth is severed, so interlaced and interwoven and anchored are the vines with those clinging to trees yet uncut. Then, in a moment, as some leading strand gives way, the whole mass falls—smothered, bruised, and crushed—to be left for a month and more before the fires destroy the faded relics of the erstwhile gloriously rampant jungle. In all this the lawyer cane is the most aggressive and hostile. Not only are there prickles on the 10-feet thongs, but the leaves and leaf-sheaths are thickly beset. In one species the 6-feet-long leaves bear upon the margins and upper surface long, thin, needle-like points, black and glossy, and attaining a length Of 3 inches; the main rib bears stout re-curved prickles, while the sheaths which envelop the cane are densely covered with dark brown or black points 1 inch and more long.
