So much have we seen on one little shell. But there is more to see close to it. Those yellow plants which I likened to squirrels’ tails and lobsters’ horns, and what not, are zoophytes of different kinds. Here is Sertularia argentea (true squirrel’s tail); here, S. filicula, as delicate as tangled threads of glass; here, abietina; here, rosacea. The lobsters’ horns are Antennaria antennina; and mingled with them are Plumulariæ, always to be distinguished from Sertulariæ by polypes growing on one side of the branch, and not on both. Here is falcata, with its roots twisted round a sea-weed. Here is cristata, on the same weed; and here is a piece of the beautiful myriophyllum, which has been battered in its long journey out of the deep water about the ore rock. For all these you must consult Johnson’s “Zoophytes,” and for a dozen smaller species, which you would probably find tangled among them, or parasitic on the sea-weed. Here are Flustræ, or sea-mats. This, which smells very like Verbena, is Flustra coriacea (Pl. I. Fig. 2). That scurf on the frond of ore-weed is F. lineata (Pl. Fig. 1). The glass bells twined about this Sertularia are Campanularia syringa (Pl. I. Fig. 9); and here is a tiny plant of Cellularia ciliata (Pl. I. Fig. 8). Look at it through the field-glass; for it is truly wonderful. Each polype cell is edged with whip-like spines, and on the back of some of them is—what is it, but a live vulture’s head, snapping and snapping—what for?
Nay, reader, I am here to show you what can be seen: but as for telling you what can be known, much more what cannot, I decline; and refer you to Johnson’s “Zoophytes,” wherein you will find that several species of polypes carry these same birds’ heads: but whether they be parts of the polype, and of what use they are, no man living knoweth.
Next, what are the striped pears? They are sea-anemones, and of a species only lately well known, Sagartia viduata, the snake-locked anemone (Pl. V. Fig. 3 {74}). They have been washed off the loose stones to which they usually adhere by the pitiless roll of the ground-swell; however, they are not so far gone, but that if you take one of them home, and put it in a jar of water, it will expand into a delicate compound flower, which can neither be described nor painted, of long pellucid tentacles, hanging like a thin bluish cloud over a disk of mottled brown and grey.
Here, adhering to this large whelk, is another, but far larger and coarser. It is Sagartia parasitica, one of our largest British species; and most singular in this, that it is almost always (in Torbay, at least,) found adhering to a whelk: but never to a live one; and for this reason. The live whelk (as you may see for yourself when the tide is out) burrows in the sand in chase of hapless bivalve shells, whom he bores through with his sharp tongue (always, cunning fellow, close to the hinge, where the fish is), and then sucks out their life. Now, if the anemone stuck to him, it would be carried under the sand daily, to its own disgust. It prefers, therefore, the dead whelk, inhabited by a soldier crab, Pagurus Bernhardi (Pl. II. Fig. 2), of which you may find a dozen anywhere as the tide goes out; and travels about at the crab’s expense, sharing with him the offal which is his food. Note, moreover, that the soldier crab is the most hasty and blundering of marine animals, as active as a monkey, and as subject to panics as a horse; wherefore the poor anemone on his back must have a hard life of it; being knocked about against rocks and shells, without warning, from morn to night and night to morn. Against which danger, kind Nature, ever maxima in minimis, has provided by fitting him with a stout leather coat, which she has given, I believe, to no other of his family.
Next, for the babies’ heads, covered with prickles, instead of hair. They are sea-urchins, Amphidotus cordatus, which burrow by thousands in the sand. These are of that Spatangoid form, which you will often find fossil in the chalk, and which shepherd boys call snakes’ heads. We shall soon find another sort, an Echinus, and have time to talk over these most strange (in my eyes) of all living animals.
There are a hundred more things to be talked of here: but we must defer the examination of them till our return; for it wants an hour yet of the dead low spring-tide; and ere we go home, we will spend a few minutes at least on the rocks at Livermead, where awaits us a strong-backed quarryman, with a strong-backed crowbar, as is to be hoped (for he snapped one right across there yesterday, falling miserably on his back into a pool thereby), and we will verify Mr. Gosse’s observation, that—
“When once we have begun to look with curiosity on the strange things that ordinary people pass over without notice, our wonder is continually excited by the variety of phase, and often by the uncouthness of form, under which some of the meaner creatures are presented to us. And this is very specially the case with the inhabitants of the sea. We can scarcely poke or pry for an hour among the rocks, at low-water mark, or walk, with an observant downcast eye, along the beach after a gale, without finding some oddly-fashioned, suspicious-looking being, unlike any form of life that we have seen before. The dark concealed interior of the sea becomes thus invested with a fresh mystery; its vast recesses appear to be stored with all imaginable forms; and we are tempted to think there must be multitudes of living creatures whose very figure and structure have never yet been suspected.
“‘O sea! old sea! who yet knows half Of thy wonders or thy pride!’”
GOSSE’S Aquarium, pp. 226, 227.
These words have more than fulfilled themselves since they were written. Those Deep-Sea dredgings, of which a detailed account will be found in Dr. Wyville Thomson’s new and most beautiful book, “The Depths of the Sea,” have disclosed, of late years, wonders of the deep even more strange and more multitudinous than the wonders of the shore. The time is past when we thought ourselves bound to believe, with Professor Edward Forbes, that only some hundred fathoms down, the inhabitants of the sea-bottom “become more and more modified, and fewer and fewer, indicating our approach towards an abyss where life is either extinguished, or exhibits but a few sparks to mark it’s lingering presence.”
Neither now need we indulge in another theory which had a certain grandeur in it, and was not so absurd as it looks at first sight,—namely, that, as Dr. Wyville Thomson puts it, picturesquely enough, “in going down the sea water became, under the pressure, gradually heavier and heavier, and that all the loose things floated at different levels, according to their specific weight,—skeletons of men, anchors and shot and cannon, and last of all the broad gold pieces lost in the wreck of many a galleon off the Spanish Main; the whole forming a kind of ‘false bottom’ to the ocean, beneath which there lay all the depth of clear still water, which was heavier than molten gold.”
The facts are; first that water, being all but incompressible, is hardly any heavier, and just as liquid, at the greatest depth, than at the surface; and that therefore animals can move as freely in it in deep as in shallow water; and next, that as the fluids inside the body of a sea animal must be at the same pressure as that of the water outside it, the two pressures must balance each other; and the body, instead of being crushed in, may be unconscious that it is living under a weight of two or three miles of water. But so it is; as we gather our curiosities at low-tide mark, or haul the dredge a mile or two out at sea, we may allow our fancy to range freely out to the westward, and down over the subaqueous cliffs of the hundred-fathom line, which mark the old shore of the British Isles, or rather of a time when Britain and Ireland were part of the continent, through water a mile, and two, and three miles deep, into total darkness, and icy cold, and a pressure which, in the open air, would crush any known living creature to a jelly; and be certain that we shall find the ocean-floor teeming everywhere with multitudinous life, some of it strangely like, some strangely unlike, the creatures which we see along the shore.
Some strangely like. You may find, for instance, among the sea-weed, here and there, a little black sea-spider, a Nymphon, who has this peculiarity, that possessing no body at all to speak of, he carries his needful stomach in long branches, packed inside his legs. The specimens which you will find will probably be half an inch across the legs. An almost exactly similar Nymphon has been dredged from the depths of the Arctic and Antarctic oceans, nearly two feet across.
You may find also a quaint little shrimp, Caprella, clinging by its hind claws to sea-weed, and waving its gaunt grotesque body to and fro, while it makes mesmeric passes with its large fore claws,—one of the most ridiculous of Nature’s many ridiculous forms. Those which you will find will be some quarter of an inch in length; but in the cold area of the North Atlantic, their cousins, it is now found, are nearly three inches long, and perch in like manner, not on sea-weeds, for there are none so deep, but on branching sponges.
These are but two instances out of many of forms which were supposed to be peculiar to shallow shores repeating themselves at vast depths: thus forcing on us strange questions about changes in the distribution and depth of the ancient seas; and forcing us, also, to reconsider the old rules by which rocks were distinguished as deep-sea or shallow-sea deposits according to the fossils found in them.
As for the new forms, and even more important than them, the ancient forms, supposed to have been long extinct, and only known as fossils, till they were lately rediscovered alive in the nether darkness,—for them you must consult Dr. Wyville Thomson’s book, and the notices of the “Challenger’s” dredgings which appear from time to time in the columns of “Nature;” for want of space forbids my speaking of them here.
But if you have no time to read “The Depths of the Sea,” go at least to the British Museum, or if you be a northern man, to the admirable public museum at Liverpool; ask to be shown the deep-sea forms; and there feast your curiosity and your sense of beauty for an hour. Look at the Crinoids, or stalked star-fishes, the “Lilies of living stone,” which swarmed in the ancient seas, in vast variety, and in such numbers that whole beds of limestone are composed of their disjointed fragments; but which have vanished out of our modern seas, we know not why, till, a few years since, almost the only known living species was the exquisite and rare Pentacrinus asteria, from deep water off the Windward Isles of the West Indies.
Of this you will see a specimen or two both at Liverpool and in the British Museum; and near them, probably, specimens of the new-old Crinoids, discovered of late years by Professor Sars, Mr. Gwyn Jeffreys, Dr. Carpenter, Dr. Wyville Thomson, and the other deep-sea disciples of the mythic Glaucus, the fisherman, who, enamoured of the wonders of the sea, plunged into the blue abyss once and for all, and became himself “the blue old man of the sea.”
Next look at the corals, and Gorgonias, and all the sea-fern tribe of branching polypidoms, and last, but not least, at the glass sponges; first at the Euplectella, or Venus’s flower-basket, which lives embedded in the mud of the seas of the Philippines, supported by a glass frill “standing up round it like an Elizabethan ruff.” Twenty years ago there was but one specimen in Europe: now you may buy one for a pound in any curiosity shop. I advise you to do so, and to keep—as I have seen done—under a glass case, as a delight to your eyes, one of the most exquisite, both for form and texture, of natural objects.
Then look at the Hyalonemas, or glass-rope ocean floor by a twisted wisp of strong flexible flint needles, somewhat on the principle of a screw-pile. So strange and complicated is their structure, that naturalists for a long while could literally make neither head nor tail of them, as long as they had only Japanese specimens to study, some of which the Japanese dealers had, of malice prepense, stuck upside down into Pholas-borings in stones. Which was top and which bottom; which the thing itself, and which special parasites growing on it; whether it was a sponge, or a zoophyte, or something else; at one time even whether it was natural, or artificial and a make-up,—could not be settled, even till a year or two since. But the discovery of the same, or a similar, species in abundance from the Butt of the Lows down to Setubal on the Portuguese coast, where the deep-water shark fishers call it “sea-whip,” has given our savants specimens enough to make up their minds—that they really know little or nothing about it, and probably will never know.
And do not forget, lastly, to ask, whether at Liverpool or at the British Museum, for the Holtenias and their congeners,—hollow sponges built up of glassy spicules, and rooted in the mud by glass hairs, in some cases between two and three feet long, as flexible and graceful as tresses of snow-white silk.
Look at these, and a hundred kindred forms, and then see how nature is not only “maxima in minimis”—greatest in her least, but often “pulcherrima in abditis”—fairest in her most hidden works; and how the Creative Spirit has lavished, as it were, unspeakable artistic skill on lowly-organized creature, never till now beheld by man, and buried, not only in foul mud, but in their own unsightly heap of living jelly.
But so it was from the beginning;—and this planet was not made for man alone. Countless ages before we appeared on earth the depths of the old chalk-ocean teemed with forms as beautiful and perfect as those, their lineal descendants, which the dredge now brings up from the Atlantic sea-floor; and if there were—as my reason tells me that there must have been—final moral causes for their existence, the only ones which we have a right to imagine are these—that all, down to the lowest Rhizopod, might delight themselves, however dimly, in existing; and that the Lord might delight Himself in them.
Thus, much—alas! how little—about the wonders of the deep. We, who are no deep-sea dredgers, must return humbly to the wonders of the shore. And first, as after descending the gap in the sea-wall we walk along the ribbed floor of hard yellow sand, let me ask you to give a sharp look-out for a round grey disc, about as big as a penny-piece, peeping out on the surface. No; that is not it, that little lump: open it, and you will find within one of the common little Venus gallina.—The closet collectors have given it some new name now, and no thanks to them: they are always changing the names, instead of studying the live animals where Nature has put them, in which case they would have no time for word-inventing. Nay, I verify suspect that the names grow, like other things; at least, they get longer and longer and more jaw-breaking every year. The little bivalve, however, finding itself left by the tide, has wisely shut up its siphons, and, by means of its foot and its edges, buried itself in a comfortable bath of cool wet sand, till the sea shall come back, and make it safe to crawl and lounge about on the surface, smoking the sea-water instead of tobacco. Neither is that depression what we seek. Touch it, and out poke a pair of astonished and inquiring horns: it is a long-armed crab, who saw us coming, and wisely shovelled himself into the sand by means of his nether-end. Corystes Cassivelaunus is his name, which he is said to have acquired from the marks on his back, which are somewhat like a human face. “Those long antennæ,” says my friend, Mr. Lloyd {90}—I have not verified the fact, but believe it, as he knows a great deal about crabs, and I know next to nothing—“form a tube through which a current of water passes into the crab’s gills, free from the surrounding sand.” Moreover, it is only the male who has those strangely long fore-arms and claws; the female contenting herself with limbs of a more moderate length. Neither is that, though it might be, the hole down which what we seek has vanished: but that burrow contains one of the long white razors which you saw cast on shore at Paignton. The boys close by are boring for them with iron rods armed with a screw, and taking them in to sell in Torquay market, as excellent food. But there is one, at last—a grey disc pouting up through the sand. Touch it, and it is gone down, quick as light. We must dig it out, and carefully, for it is a delicate monster. At last, after ten minutes’ careful work, we have brought up, from a foot depth or more—what? A thick, dirty, slimy worm, without head or tail, form or colour. A slug has more artistic beauty about him. Be it so. At home in the aquarium (where, alas! he will live but for a day or two, under the new irritation of light) he will make a very different figure. That is one of the rarest of British sea-animals, Peachia hastata (Pl. XII. Fig. 1), which differs from most other British Actiniæ in this, that instead of having like them a walking disc, it has a free open lower end, with which (I know not how) it buries itself upright in the sand, with its mouth just above the surface. The figure on the left of the plate represents a curious cluster of papillæ which project from one side of the mouth, and are the opening of the oviduct. But his value consists, not merely in his beauty (though that, really, is not small), but in his belonging to what the long word-makers call an “interosculant” group,—a party of genera and species which connect families scientifically far apart, filling up a fresh link in the great chain, or rather the great network, of zoological classification. For here we have a simple, and, as it were, crude form; of which, if we dared to indulge in reveries, we might say that the Creative Mind realized it before either Actiniæ or Holothurians, and then went on to perfect the idea contained in it in two different directions; dividing it into two different families, and making on its model, by adding new organs, and taking away old ones, in one direction the whole family of Actiniæ (sea-anemones), and in a quite opposite one the Holothuriæ, those strange sea-cucumbers, with their mouth-fringe of feathery gills, of which you shall see some anon. Thus there has been, in the Creative Mind, as it gave life to new species, a development of the idea on which older species were created, in order—we may fancy—that every mesh of the great net might gradually be supplied, and there should be no gaps in the perfect variety of Nature’s forms. This development is one which we must believe to be at least possible, if we allow that a Mind presides over the universe, and not a mere brute necessity, a Law (absurd misnomer) without a Lawgiver; and to it (strangely enough coinciding here and there with the Platonic doctrine of Eternal Ideas existing in the Divine Mind) all fresh inductive discovery seems to point more and more.
Let me speak freely a few words on this important matter. Geology has disproved the old popular belief that the universe was brought into being as it now exists by a single fiat. We know that the work has been gradual; that the earth
“In tracts of fluent heat began, The seeming prey of cyclic storms, The home of seeming random forms, Till, at the last, arose the man.”
And we know, also, that these forms, “seeming random” as they are, have appeared according to a law which, as far as we can judge, has been on the whole one of progress,—lower animals (though we cannot yet say, the lowest) appearing first, and man, the highest mammal, “the roof and crown of things,” one of the latest in the series. We have no more right, let it be observed, to say that man, the highest, appeared last, than that the lowest appeared first. It was probably so, in both cases; but there is as yet no positive proof of either; and as we know that species of animals lower than those which already existed appeared again and again during the various eras, so it is quite possible that they may be appearing now, and may appear hereafter: and that for every extinct Dodo or Moa, a new species may be created, to keep up the equilibrium of the whole. This is but a surmise: but it may be wise, perhaps, just now, to confess boldly, even to insist on, its possibility, lest any should fancy, from our unwillingness to allow it, that there would be ought in it, if proved, contrary to sound religion.
I am, I must honestly confess, more and more unable to perceive anything which an orthodox Christian may not hold, in those physical theories of “evolution,” which are gaining more and more the assent of our best zoologists and botanists. All that they ask us to believe is, that “species” and “families,” and indeed the whole of organic nature, have gone through, and may still be going through, some such development from a lowest germ, as we know that every living individual, from the lowest zoophyte to man himself, does actually go through. They apply to the whole of the living world, past, present, and future, the law which is undeniably at work on each individual of it. They may be wrong, or they may be right: but what is there in such a conception contrary to any doctrine—at least of the Church of England? To say that this cannot be true; that species cannot vary, because God, at the beginning, created each thing “according to its kind,” is really to beg the question; which is—Does the idea of “kind” include variability or not? and if so, how much variability? Now, “kind,” or “species,” as we call it, is defined nowhere in the Bible. What right have we to read our own definition into the word?—and that against the certain fact, that some “kinds” do vary, and that widely,—mankind, for instance, and the animals and plants which he domesticates. Surely that latter fact should be significant, to those who believe, as I do, that man was created in the likeness of God. For if man has the power, not only of making plants and animals vary, but of developing them into forms of higher beauty and usefulness than their wild ancestors possessed, why should not the God in whose image he is made possess the same power? If the old theological rule be true—“There is nothing in man which was not first in God” (sin, of course, excluded)—then why should not this imperfect creative faculty in man be the very guarantee that God possesses it in perfection?
