The Island Home

by Richard Archer

I looked down into the water, and saw what in fact, seemed to be a gigantic shell-fish, gripping both his legs: it retained its hold so tenaciously, that I found I could not extricate him, and when Arthur came up, as he did in a moment, it was as much as we could both do, to lift him and his singular captor, which still clung obstinately to him, out of the crevice. We were then obliged to pry open the shells with our cutlasses before we could release him.

Arthur pronounced this extraordinary shell-fish, to be a specimen of the “Chama Gigas.” The shells were nearly three feet in length, and curiously marked and clouded. Johnny had slipped from the slimy edge of the chasm, and happened to fall fairly into the expanded jaws of the chama, which, had instantly closed upon him. If the water had been deeper, the consequences might have been serious, as there are instances of persons being drowned, by having their feet caught in the vice-like grip of this formidable bivalve.

Not far from the scene of Johnny’s mishap, was a green spot upon the reef, where a group of young trees seemed to spring up out of the bare coral. On approaching the place, we found that a little island, about the size of Palm-islet was there in process of formation. Notwithstanding the exposed and barren character of the locality, and the scantiness of the soil, which was not anywhere a foot in depth. It was covered with a thrifty vegetation, among which were several well-grown-palms, a group of young casuarinas, and some ferns and tournefortias. Nor was this embryo islet destitute of inhabitants. The trees were at this hour filled with aquatic birds, and I observed among them one remarkable species, long-bodied, and slender, like swallows, with red bills and feet, white breast, and slate-coloured wings; these, instead of perching, like the rest of their feathered associates, upon the trees, nestled in the concavity of the long palm-leaves, far enough from the stem, to be rocked gently by the undulating motion of the leaf, which a breath of wind, or the slightest stirring of the birds in these swinging nets was sufficient to produce. But by far the most numerous and singular portion of the population of the islet, consisted of a species of large land-crab, inhabiting burrows hollowed out beneath the roots of the trees. Great numbers of them appeared to be bathing or sporting in the shallow water on the lagoon side of the islet, but, at sight of us, they scrambled off to their burrows with a degree of agility that could hardly have been expected from such clumsy-looking creatures. Owing partly to this unlooked-for rapidity of locomotion, and partly to a natural shyness and hesitation which we felt about handling them rashly, (their pincer-like jaws, with half a dozen pairs of which each individual seemed to be provided, having a rather formidable appearance), they escaped before we could capture even a specimen. Johnny forthwith posted himself in ambush among a bunch of fern, and riveting his eyes upon one of the burrows at the foot of a young cocoa-nut tree, waited impatiently for the crabs to venture forth once more. In a few moments a patriarchal-looking old fellow emerged cautiously from the hole, and was presently followed by several more. Johnny prudently delayed any hostile movement, until they should get far enough from their place of security to enable him to cut off their retreat; and, in the meantime, I was greatly amused and interested in observing the ingenious method in which the patriarch commenced operating upon a cocoa-nut which had fallen to the ground near his den.

Managing his complicated apparatus of claws with surprising dexterity, he seized the nut, and stripped off the outer husk in a twinkling; then setting it upon one end, he began to hammer away at the orifices through which the stalk and root of the future tree make their way when the nut germinates. Having at length removed the filling up of these orifices, he inserted a claw, and actually split the strong inner shell, dividing it neatly into halves. At this stage of the proceedings, half a dozen greedy neighbours, who had been looking on, without offering a helping claw, shuffled nimbly forward to share the spoil, and it was curious to see how quickly they cleaned out the shell, leaving not a particle of the kernel. Johnny seized this as a favourable moment for a sally, and rushed forth cutlass in hand, having adopted the discreet resolution of disabling them, by lopping off those formidable claws, before coming to close quarters. The sally, however, was premature, and proved entirely unsuccessful, for the crabs backed and sidled into their burrows with such expedition, that the last of them disappeared before their assailant could get within reach. Leaving Johnny to renew his ambuscade, if so disposed, I proceeded along the reef, and found Max and Browne bathing for the second time that day. They had discovered a charming place for the purpose, where a kind of oval basin was formed by the lagoon setting into the inside of the reef. The water was deep and clear, so that there was no danger of wounding the feet by means of shells or corals. Max had discovered what he supposed to be an enormous pearl-oyster, attached to a wall of coral, at the depth of five or six fathoms, and they were diving for it alternately. Both succeeded in reaching it, but it adhered so firmly to the rock by its strong beard, that neither of the amateur pearl-divers could tear it off, and getting soon exhausted and out of breath, they abandoned the attempt.

The submarine scenery of the lagoon was in this spot unusually varied and beautiful, and the basin formed a bath, fit for the Nereids themselves. Numbers of different kinds of shell-fish were attached to the coral branches, or wedged into their interstices. Others were feeding, and reflected the brightest colours with every motion. Purple mullet, variegated rock-fish, and small ray-fish, were darting about near the bottom. Another species of mullet, of a splendid changeable blue and green, seemed to be feeding upon the little polyps protruding from the coral tops. Shells, sea-plants, coral, and fishes, and the slightest movement of the latter, even to the vibration of a tiny fin! or the gentle opening of the gills in respiration, could be seen with perfect distinctness in this transparent medium. But what chiefly attracted attention, was the gay tints, and curious shapes, of the innumerable zoophytes, or “flower animals,” springing up from the sides and bottom of the basin, and unfolding their living leaves above their limestone trunks or stems which encased them. Blue, red, pink, orange, purple, and green, were among the colours, and the variety of patterns seemed absolutely endless: they mimicked, in their manner of growth, the foliage of trees, the spreading antlers of the stag, globes, columns, stars, feathery plumes, trailing vines, and all the wildest and most graceful forms of terrestrial vegetation. Nothing was wanting to complete this submarine shrubbery, even to the minutest details; there were mosses, and ferns, and lichens, and spreading shrubs, and branching trees; bunches of slender thread-like stems, swaying gently with the motion of the water, might, (except for their pale, purplish, tint), pass for rushes, or tussocks of reedy grass; and it required no effort of the imagination to see fancifully shaped wild-flowers in the numerous varieties of actiniae, or sea anemones, many of which bore the closest resemblance to wood-pinks, asters, and carnations. The imitations of these flowers were in some cases wonderfully perfect, even to their delicate petals, which were represented by the slender, fringe-like tentacles of the living polyp, protruding from its cell. Besides these counterparts of land vegetation, there were waving sea-fans, solid masses of sponge-coral, clubs of Hercules, madrepores, like elegantly-formed vases filled with flowers, dome-like groups of astraeae, studded with green and purple spangles, and a thousand other shapes, so fantastic and peculiar, that they can be likened to no other objects in nature.

Johnny having got tired of lying in wait for the crabs, came to watch the swimmers and search for shells. In the course of frequent beach excursions with Mr Frazer, he had picked up the names, and chief distinguishing characteristics of the principal genera of marine shells, in consequence of which he had at length come to regard himself as quite a conchologist, and was ambitious of making a “collection,” like other naturalists, in which design Arthur encouraged and assisted him.

Joining me, where I was lying upon a flat ledge, peering down into the basin, he presently espied a Triton’s trumpet, more than a foot in length, in some five fathoms of water, and pointing it out to Max, he begged him to dive for it, earnestly assuring him that he had never seen so fine a specimen of the “Murex Tritonica.” But the latter very decidedly declined sacrificing his breath in the cause of science, declaring that he had completely exhausted himself by his exertions in pearl-diving.

Eiulo coming up at the moment with a number of shell-fish which he had obtained, Johnny appealed to him for aid, and not in vain, for as soon as the much-coveted shell was pointed out to him, he threw off his wrapper, and plunging into the water, almost instantly returned with it. Max now showed him the supposed pearl-oyster, and challenged him to make an attempt to bring it up. Eiulo laughed, and nodded his acceptance of the challenge: after pausing a moment to take breath, he dived perpendicularly downward, reaching the shell easily with a few strokes, and made one or two vigorous but ineffectual jerks at it; then, just as I thought him about to give it up, and ascend again, he grasped it with both hands, brought his feet under him, and bracing himself firmly against the wall of coral, he wrenched it off, and bore the prize in triumph to the surface. It proved to be a pearl-oyster, as Max had supposed, and on being opened was found to contain eleven seed-pearls. Eiulo presented the shell and its contents to Johnny, who seemed to value the former, quite as much as the latter, and presently ran off in search of Arthur, to inquire whether it should properly be classed with the “genus ostrea,” or the “genus mytilus.”

After watching the swimmers a little longer, I strolled along the reef, in the direction which Johnny had taken in pursuit of Arthur, stopping occasionally to watch the bursting of a wave of uncommon magnitude, or to examine some of the interesting objects that were strewn with such profusion in every direction, and which rendered that barren ledge so choice a spot for the studies of the naturalist. Some ten or fifteen minutes had been thus employed, and it was beginning to grow dark, so that Arthur and Johnny, whom I had not yet overtaken, could be but just distinguished, like two specks in the distance, when I heard the powerful voice of Browne, raised in a loud and prolonged halloo. Pausing to listen, I soon heard the cry repeated, in a manner that showed as I thought, that something unusual had taken place. Hastening back, I found that Max and Browne had swum off to a coral knoll, in the lagoon, a stone’s throw from the reef, and dared not venture back, being closely blockaded by a large fish swimming about near the spot, which they supposed to be a shark. They called loudly for me to come after them in the boat, and to lose no time about it, as there was water enough on the knoll, to enable a shark, if tolerably enterprising, to reach them where they stood. Though it was rapidly getting dark, there was still sufficient light to enable me to distinguish an enormous fish of some kind, cruising back and forth, with the regularity of a sentinel on duty, between the reef, and the shallow where Max and Browne were standing up to their knees in water. The case appeared to admit of no delay, and jumping into the boat, I pulled over to the coral patch with all possible speed, passing the fish close enough to see that it was in fact a large shark, and he proved also to be an exceedingly fierce and ravenous one. It almost seemed as though he understood my errand, for he followed, or rather attended me, closely, keeping so near the bow of the boat that it was with great difficulty and some danger, that I at length got the blockaded swimmers aboard. When this was effected, his disappointment and consequent bad temper were quite apparent; he swam round and round the boat in the most disturbed and agitated manner as we returned, making a variety of savage demonstrations, and finally going so far as to snap spitefully at the oars, which he did not discontinue, until Browne had two or three times rapped him smartly over the nose. After landing in safety, Max pelted him with shells and pieces of coral rock, until he finally swam off.

Meantime, Arthur and Johnny had returned from their wandering along the reef; the latter had come across another colony of crabs, and had succeeded in capturing three of them, or rather two and a half, for having, as he fondly imagined, disabled one enormous fellow by hacking him in two with his cutlass, the one half had scrambled into the hole, while Johnny was securing the other.
