What a difference, too, has Nature established, in the natural power to resist pressure, between those creatures which float near the surface and those which haunt the deeper sea! The Jelly-fish can live only near the top of the water, and, floating softly through a gentle medium, is yet crushed by a touch; while the Coral-builder bears the superincumbent weight of worlds on his vaulted cell with perfect impunity.

Another important question is, How far alteration in the amount of light may affect the more delicate creatures. What fishes do without light has been solved by the darkness of the Mammoth Cave, the tenants of whose black pools are eyeless, evidently because there is nothing to see. The more deeply located Infusoria and Mollusks must dwell in an endless twilight; for Humboldt has found, by experiment, that at a depth one hundred and ninety-two feet from the surface the amount of sunlight which can penetrate is equal only to one-half of the light of an ordinary candle one foot distant.

Thus ever in gloom, yet in a state of constant safety from storms and the agitations of the upper air, the thousand forms of low organic life and cryptogamic vegetation live and thrive in peace and quietness.

 
  "The floor is of sand like the mountain drift,
  And the pearl-shells spangle the flinty snow;
  From the coral rocks the sea-plants lift
  Their boughs, where the tides and billows flow.
* * * * *
  "And life in rare and beautiful forms
  Is sporting amid those bowers of stone,
  And is safe, when the wrathful spirit of storms
  Has made the top of the waves his own."⁴⁷
 

Upon the bottom, at various depths, lies that brilliant Radiate—type of his class—the Star-fish. These are quiet and harmless creatures, and favorites in the aquarium, from the pretty contrast they make with marine plants and other objects.

The perfect transparency, elegant form, and graceful navigation of the Medusae, or Jelly-fishes, render them much admired in their native haunts, and prized for the aquarium. But they are very delicate. How beautiful and remarkable are these headless Discophori, as they float, and propel themselves with involutions of their disks and gently trailing tentacles, and the central peduncle hanging far below, like the clapper of a transparent bell! And yet these wonders are but so much sea-water, inclosed in so slight a tissue that it withers in the sun, and leaves only a minute spot of dried-up gelatinous substance behind.

Finally come the Fishes, many of which are of similar genera to those recommended for the fresh-water tank. The Black Goby is familiar, tamable, but voracious; the Gray Mullet is very hardy, but also rather savage; the Wrasses are some of the most showy fish,—called in some parts of the country Cunners,—and of these, the Ancient Wrasse, (Labrus maculatus,) covered with a network of vermilion meshes on a brown and white ground, is the most elegant.

Some points of general management are so important, and some dangers so imminent, that we cannot pass them by unnoticed. The aquarian enthusiast is very apt to be in too great haste to see everything going on, and commits the common error of trying too many things at once. The aquarium must be built up slowly and tentatively, object by object: plants first, and of the simplest kinds; and not until they are well settled, and the water beaded with oxygen bubbles, should we think of introducing living creatures,—and even then only the hardier kinds of actinias, mollusks, and crabs. All delicate animals must be intrusted one by one to their new home, and carefully watched for deaths and decay, which, whether arising from dead plants or animals, ruin everything very quickly, unless they be promptly removed. For sulphuretted hydrogen, even in very minute quantities, is sure death to all these little creatures.

The emanations from paint and putty are often fatal in new tanks. Several weeks' exposure to water, air, and sunlight is necessary to season the new-made aquarium. Of equal consequence is it that the water be absolutely pure; and if brought from the sea, care must be exercised about the vessel containing it. Salt acts upon the glazing of earthen ware of some kinds. Stone or glass jars are safest. New oak casks are fatal from the tannin which soaks out; fir casks are safe and good. So delicate and sensitive are the minute creatures which people the sea, that they have been found dead on opening a cask in which a new oak bung was the only source of poison. And no wonder; for a very slight proportion of tannic acid in the water corrugates and stiffens the thin, smooth skin of the anemone, like the tanning of leather.

A certain natural density of the sea-water must also be preserved, ranging between no wider limits than 1026 and 1028. And in the open tank evaporation is constantly deranging this, and must be met by a supply from without. As the pure water alone evaporates, and the salts and earthy or mineral constituents are left behind, two things result: the water remaining becomes constantly more dense; and this can be remedied only by pure fresh water poured in to restore the equilibrium. Hence the marine aquarium must be replenished with fresh water, until the proper specific gravity, as indicated by the hydrometer, is restored.

The aquarium may be found some morning with a deep and permanent green stain discoloring the water. This unsightly appearance is owing to the simultaneous development of the spores of multitudes of minute Algae and Confervae, and can be obviated by passing the water through a charcoal filter. When any of the fishes give signs of sickness or suffocation, by coming to the surface and gulping air, they may be revived by having the water aerated by pouring it out repeatedly from a little elevation, or by a syringe. The fishes are sometimes distressed, also, when the room gets too warm for them. A temperature of 60° is about what they require. And they will stand cold, many of them, even to being frozen with the water into ice, and afterwards revive.

The degree of light should be carefully regulated by a stained glass side, or a shade. Yet it must be borne in mind that sunlight is indispensable to the free evolution of oxygen by the plants. And when the sun is shining on the water, all its occupants appear more lively, and the fishes seem intoxicated—as they doubtless are—with oxygen.

A novice is apt to overstock his aquarium. Not more than two moderate-sized fishes to a gallon of water is a safe rule. Care, too, must be taken to group together those kinds of creatures which are not natural enemies, or natural food for each other, or a sad scene of devastation and murder will ensue.

Cleansing cannot be always intrusted to snails. But the sides may be scrubbed with a soft swab, made of cotton or wick-yarn. Deaths will occasionally take place; and even suicide is said to be resorted to by the wicked family of the Echinoderms.

To procure specimens for the aquarium requires some knack and knowledge. The sea-shore must be haunted, and even the deep sea explored. At the extreme low-water of new or full moon tides, the rocks and tide-pools are to be zealously hunted over by the aquarian naturalist. Several wide-mouthed vials and stone jars are necessary; and we would repeat, that no plant should be taken, unless its attachment is preserved. It is often a long and difficult job to get some of the Algae; with their tender connections unsevered from the hard rock, which must be chipped away with the chisel, and often with the blows of the hammer deadened by being struck under water. It is by lifting up the overhanging masses of slimy fuel, tangles, and sea-grass, that we find the delicate varieties, as the Chondrus with its metallic lustre, and the red Algae, or the stony Corallina, which delights in the obscurity of shaded pools.

The sea-weeds will be found studded with mollusks,—as Snails and Periwinkles of many queer varieties. Anemones, of the more common kinds, are found clinging to smooth stones. Crabs on the sand. Prawns, Shrimps, Medusae, and fishes of many species, in the little pools which the tide leaves behind, and which it will require a sharp eye and a quick hand to explore with success. But the rarer forms of Actinias, Star-fishes, Sepioles, Madrepores, Annelidae, and Zoophytes, of a thousand shapes, live on the bottom, in deep water, and must be captured there.

For this purpose we must dredge from a boat, under sail. The naturalist's dredge is an improved oyster-dredge, with each of the two long sides of the mouth made into a scraping lip of iron. The body is made of spun-yarn, or fishing-line, netted into a small mesh. Two long triangles are attached by a hinge to the two short sides of the frame, and meeting in front, at some distance from the mouth, are connected by a swivel-joint. To this the dragging rope is bent, which must be three times as long, in dredging, as the depth of the water. This is fastened to the stern of a boat under sail, and thus the bottom is raked of all sorts of objects; among which, on emptying the net, many living creatures for the aquarium are found. These may be placed temporarily in jars; though plants, mollusks, Crustacea and Actiniae may be kept and transmitted long distances packed in layers of moist sea-weed.

For all this detail, labor, and patient care, we may reasonably find two great objects: first, the cultivation and advancement of natural science; second, the purest delight and healthiest amusement.

In the aquarium we have a most convenient field for the study of Natural History: to learn the varieties, nature, names, habits, and peculiarities of those endless forms of animated existence which dwell in the hidden depths of the sea, and at the same time to improve our minds by cultivating our powers of observation.

The pleasure derived from the aquarium comes from the excitement of finding and collecting specimens, as well as from watching the tank itself. There can be no more pleasant accompaniment to the sea-side walk of the casual visitor or summer resident of a watering-place, than to search for marine plants and animals among the fissures, rocks, and tide-pools of the sea-washed beach or cape.

Nature is always as varied as beautiful. Thousands of strange forms sport under the shadow of the brown, waving sea-weeds, or among the delicate scarlet fronds of the dulse, which is found growing in the little ponds that the inequalities of the beach have retained. It is down among the great boulders which the Atlantic piles upon our coast, that we may find endless varieties of life to fill the aquarium, though not those more gorgeous hues which distinguish the tenants of the coral reefs on tropical shores. Yet even here Nature is absolutely infinite; and we shall find ourselves, day after day, imitating that botanist who, walking through the same path for a month, found always a new plant which had escaped his notice before. So, too, in exploring the open sea, besides the pleasure of sailing along a variegated coast, with sun and blue water, we have the constant excitement of unexpected discovery: for, as often as we pull up the dredge, some new wonder is revealed.

Words fail to describe the wonders of the sea. And all that we drag from the bottom, all that we admire in the aquarium, are but a few disconnected specimens of that infinite whole which makes up their home.

So, too, in watching the aquarium itself, we shall see endless repetitions of those "sea-changes" which Shakspeare sang. Ancient mythology typified the changing wonders of aquatic Nature, as well as the fickleness of the treacherous sea, in those shifting deities, Glaucus and Proteus, who tenanted the shore.

The one the fancy of Ovid metamorphosed from a restless man to a fickle sea-god; the other assumed so many deceptive shapes to those who visited his cave, that his memory has been preserved in the word Protean. Such fancies well apply to a part of Nature which shifts like the sands, and ranges from the hideous Cuttle-fish and ravenous Shark to the delicate Medusa, whose graceful form and trailing tentacles float among the waving fronds of colored Algae, like

 
  "Sabrina fair,
  Under the glassy, cool, translucent wave,
  In twisted braids of lilies knitting
  The loose train of her amber-dropping hair."

THE YOUNG REPEALER

About eighteen years ago, when I was confined to two rooms by illness of long standing, I received a remarkable note by post one day. The envelope, bearing the Dublin postmark, was addressed in a good, bold, manly handwriting; but the few lines within showed traces of agitation. What I am going to relate is a true story,—altogether true, so far as I can trust my memory,—except the name of the Young Repealer. I might give his real name without danger of hurting any person's feelings but one; but, for the sake of that one, who will thus be out of the reach of my narrative, I speak of him under another name. Having to choose a name, I will take a thoroughly Irish one, and call my correspondent Patrick Monahan.

The few lines which showed agitation in the handwriting were calm in language, but very strange. Patrick Monahan told me that he was extremely unhappy, and that he had reason to believe that I, and I alone, could do him good. This, with the address,—to a certain number in a street in Dublin,—was all.

There was little time before the post went out; I was almost unable to write from illness; but, after a second glance at this note, I felt that I dared not delay my reply. I did not think that it was money that he wished to ask. I did not think that he was insane. I could not conceive why he should apply to me, nor why he did not explain what he wished from me; but I had a strong impression that it was safest to reply at once. I did so, in half a dozen lines, promising to write next day, after a further attempt to discover his meaning, and begging him to consider how completely in the dark I was as to him and his case. It was well that I wrote that day. Long after, when he was letting me into all the facts of his life, he told me that he had made my replying at once or not the turning-point of his fate. If the post had brought him nothing, he would have drowned himself in the Liffey.

My second letter was the only sort of letter that it could be,—an account of my own conjectures about him, and of my regret that I could see no probability of my being of use to him, except in as far as my experience of many troubles might enable me to speak suitably to him. I added some few words on the dangers attending any sort of trouble, when too keenly felt.

In answer to my first note came a few lines, telling me that the purpose of his application was mainly answered, and that my reply was of altogether greater consequence than I could have any idea of. He was less unhappy now, and believed he should never be so desperately wretched again. Wild as this might appear, I was still persuaded that he was not insane.

By the next post came a rather bulky packet. It contained, besides a letter from him, two or three old parchment documents, which showed that Patrick's forefathers had filled some chief municipal offices in the city in which the family had been settled for several generations. I had divined that Patrick was a gentleman; and he now showed me that he came of a good and honorable family, and had been well-educated. He was an orphan, and had not a relation in the world,—if I remember right. It was evident that he was poor; but he did not ask for money, nor seem to write on that account. He aspired to a literary life, and believed he should have done so, even if he had had the means of professional education. But he did not ask me for aid in trying his powers in literature. It was very perplexing; and the fact became presently clear that he expected me to tell him how I could be of use to him,—he being in no way able to afford me that information. I may as well give here the key to the mystery, which I had to wait for for some time. When poor Patrick was in a desperate condition,—very ill, in a lodging of which he could not pay the rent,—threatened with being turned into the street as soon as the thing could be done without danger to his life,—galled with a sense of disgrace, and full of impotent wrath against an oppressor,—and even suffering under deeper griefs than these,—at such a time, the worn man fell asleep, and dreamed that I looked kindly upon him. This happened three times; and on this ground, and this alone, he applied to me for comfort.

Before I learned this much, I had taken upon me to advise freely whatever occurred to me as best, finding Patrick entirely docile under my suggestions. Among other things, I advised him not to take offence, or assume any reserve, if a gentleman should call on him, with a desire to be of use to him. A gentleman did call, and was of eminent use to him. I had written to a benevolent friend of mine, a chief citizen of Dublin, begging him to obtain for me, through some trusty clerk or other messenger, some information as to what Patrick was like,—how old he was, what he was doing, and whether anything effectual could be done for him. Mr. H. went himself. He found Patrick sitting over a little fire in a little room, his young face thin and flushed, and his thin hands showing fever. He had had inflammation of the lungs, and, though he talked cheerfully, he was yet very far from well. Mr. H. was charmed with him. He found in him no needless reserves, and not so much sensitive pride as we had feared. Patrick had great hopes of sufficient employment, when once he could get out and go and see about it; and he pointed out two or three directions in which he believed he could obtain engagements. Two things, however, were plain: that there was some difficulty about getting out, and that his mind was set upon going to London at the first possible moment. He had not only the ordinary provincial ambition to achieve an entrance into the London literary world, but he had another object: he could serve his country best in London. Mr. H. easily divined the nature of the obstacle to his going out into the fresh air which he needed so much; and in a few days Patrick had a good suit of clothes. This was Mr. H.'s doing; and he also removed the danger of Patrick's being turned out of his lodging. The landlord had no wish to do such a thing; the young man was a gentleman,—regular and self-denying in his habits, and giving no trouble that he could help: but he had been very ill; and it was so desolate! Nobody came to see him; no letters arrived for him; no money was coming in, it was clear; and he could not go on living there,—starving, in fact.

Once able to go about again, Patrick cheered up; but it was plain that there was one point on which he would not be ruled. He would not stay in Dublin, under any inducement whatever; and he would go to London. I wrote very plainly to him about the risk he was running,—even describing the desolate condition of the unsuccessful literary adventurer in the dreary peopled wilderness, in which the friendless may lie down and die alone, as the starved animal lies down and perishes in the ravine in the desert. I showed him how impossible it was for me or anybody to help him, except with a little money, till he had shown what he could do; and I entreated him to wait two years,—one year,—six months, before rushing on such a fate. Here, and here alone, he was self-willed. At first he explained to me that he had one piece of employment to rely on. He was to be the London correspondent of the Repeal organ in Dublin,—the "Nation" newspaper. The pay was next to nothing. He could not live, ever so frugally, on four times the amount: but it was an engagement; and it would enable him to serve his country. So, as there was nothing else to be done, Mr. H. started him for London, with just money enough to carry him there. Once there, he was sure he should do very well.

I doubted this; and he was met, at the address he gave, (at an Irish greengrocer's, the only person he knew in London,) by an order for money enough to carry him over two or three weeks,—money given by two or three friends to whom I ventured to open the case. I have seldom read a happier letter than Patrick's first from London; but it was not even then, nor for some time after, that he told me the main reason of his horror at remaining in Dublin.

He had hoped to support himself as a tutor while studying and practising for the literary profession; and he had been engaged to teach the children of a rich citizen,—not only the boys, but the daughter. He, an engaging youth of three-and-twenty, with blue eyes and golden hair, an innocent and noble expression of countenance, an open heart, a glowing imagination, and an eloquent tongue, was set to teach Latin and literary composition to a pretty, warm-hearted, romantic girl of twenty; and when they were in love and engaged, the father considered himself the victim of the basest treachery that ever man suffered under. In vain the young people pleaded for leave to love and wait till Patrick could provide a home for his wife. They asked no favor but to be let alone. Patrick's family was as good as hers; and he had the education and manners of a gentleman, without any objectionable habits or tastes, but with every possible desire to win an honorable home for his beloved. I am not sure, but I think there was a moment when they thought of eloping some day, if nothing but the paternal displeasure intervened between them and happiness; but it was not yet time for this. There was much to be done first. What the father did first was to turn Patrick out of the house, under such circumstances of ignominy as he could devise. What he did next was the blow which broke the poor fellow down. Patrick had written a letter, in answer to the treatment he had received, in which he expressed his feelings as strongly as one might expect. This letter was made the ground of a complaint at the police-office; and Patrick was arrested, marched before the magistrate, and arraigned as the sender of a threatening letter to a citizen. In vain he protested that no idea of threatening anybody had been in his mind. The letter, as commented on by his employer, was pronounced sufficiently menacing to justify his being bound over to keep the peace towards this citizen and all his family. The intention was, no doubt, to disgrace him, and put him out of the question as a suitor; for no man could pretend to be really afraid of violence from a candid youth like Patrick, who loved the daughter too well to lift a finger against any one connected with her. The scheme succeeded; for he believed it had broken his heart. He supposed himself utterly disgraced in Dublin; and he could live there no longer. Hence his self-will about going to London.

In addition to this personal, there was a patriotic view. Very early in our correspondence, Patrick told me that he was a Repealer. He fancied himself a very moderate one, and likely on that account to do the more good. Those were the days of O'Connell's greatest power; or, if it was on the wane, no one yet recognized any change. Patrick knew one of the younger O'Connells, and had been flatteringly noticed by the great Dan himself, who had approved the idea of his going to London, hoped to see him there some day, and had prophesied that this young friend of his would do great things for the cause by his pen, and be conspicuous among the saviours of Ireland. Patrick's head was not quite turned by this; and he lamented, in his letters to me, the plans proposed and the language held by the common run of O'Connell's followers. Those were the days when the Catholic peasantry believed that "Repale" would make every man the owner of the land he lived on, or of that which he wished to live on; and the great Dan did not disabuse them. Those were the days when poor men believed that "Repale" would release every one from the debts he owed; and Dan did not contradict it. When Dan was dead, the consequence of his not contradicting it was that a literal-minded fellow here and there shot the creditor who asked for payment of the coat, or the pig, or the meal. For all this delusion Patrick was sorry. He was sorry to hear Protestant shopmen wishing for the day when Dublin streets would be knee-deep in Catholic blood, and to hear Catholic shopmen reciprocating the wish in regard to Protestant blood. He was anxious to make me understand that he had no such notions, and that he even thought O'Connell mistaken in appearing to countenance such mistakes. But still he, Patrick, was a Repealer; and he wished me to know precisely what he meant by that, and what he proposed to do in consequence. He thought it a sin and shame that Ireland should be trodden under the heel of the Saxon; he thought the domination of the English Parliament intolerable; he considered it just that the Irish should make their own laws, own their own soil, and manage their own affairs. He had no wish to bring in the French, or any other enemy of England; and he was fully disposed to be loyal to the Crown, if the Crown would let Ireland entirely alone. Even the constant persecution inflicted upon Ireland had not destroyed his loyalty to the Crown. Such were the views on which his letters to the "Nation" newspaper were to be grounded. In reply, I contented myself with proposing that he should make sure of his ground as he went along; for which purpose he should ascertain what proportion of the people of Ireland wished for a repeal of the Union; and what sort of people they were who desired Repeal on the one hand, or continued Union on the other. I hoped he would satisfy himself as to what Repeal could and could not effect; and that he would study the history of Irish Parliaments, to learn what the character and bearing of their legislation had been, and to estimate the chances of good government by that kind of legislature, in comparison with the Imperial Parliament.

If any foreign reader should suppose it impossible, that, in modern times, there can have been hopes entertained in Dublin of the streets being inundated with blood, such reader may be referred to the evidence afforded of Repeal sentiment five years later than the time of which I write. When the heroes of that rising of 1848—of whom John Mitchell is the sample best known in America—were tracked in their plans and devices, it appeared what their proposed methods of warfare were. Some of these, detailed in Repeal newspapers, and copied into American journals, were proposed to the patriotic women of Ireland, as their peculiar means of serving their country; and three especially. Red-hot iron hoops, my readers may remember, were to be cast down from balconies, so as to pin the arms of English soldiers marching in the street, and scorch their hearts. Vitriol was to be flung into their eyes. Boiling oil was to be poured upon them from windows. This is enough. Nobody believes that the thing would ever have been done; but the lively and repeated discussion of it shows how the feelings of the ignorant are perverted, and the passions of party-men are stimulated in Ireland, when unscrupulous leaders arise, proposing irrational projects. The consequences have been seen in Popish and Protestant fights in Ulster, and in the midnight drill of Phoenix Clubs in Munster, and in John Mitchell's passion for fat negroes in the Slave States of America. In Ireland such notions are regarded now as a delirious dream, except by a John Mitchell here and there. Smith O'Brien himself declares that there is nothing to be done while the people of Ireland are satisfied with the government they live under; and that, if it were otherwise, nothing can be done for a people which either elects jobbers to Parliament, or suspects every man of being a traitor who proceeds, when there, to do the business of his function. I suspected that Patrick would find out some of these things for himself in London; and I left him to make his own discoveries, when I had pointed out one or two paths of inquiry.

The process was a more rapid one than I had anticipated. He reported his first letter to the "Nation" with great satisfaction. He had begun his work in London. He went to the House of Commons, and came away sorely perplexed. After having heard and written so much of the wrongs of Ireland under the domination of the English Parliament, he found that Ireland actually and practically formed a part of that Parliament,—the legislature being, not English, but Imperial. He must have known this before; but he had never felt it. He now saw that Ireland was as well represented as England or Scotland; that political offices were held in fair proportion by Irishmen; and that the Irish members engrossed much more than a fair share of the national time in debate and projects of legislation. He saw at once that here was an end of all excuse for talk of oppression by Parliament, and of all complaints which assumed that Ireland was unrepresented. He was previously aware that Ireland was more lightly taxed than the rest of the empire. The question remained, whether a local legislature would or would not be a better thing than a share in the Imperial Parliament. This was a fair subject of argument; but he must now dismiss all notions grounded on the mistake of Ireland being unrepresented, and oppressed by the representatives of other people.

In the letter which disclosed these new views Patrick reported his visit to O'Connell. He had reminded his friend, the junior O'Connell, of Dan's invitation to him to go to see him in London; and he had looked forward to their levee with delight and expectation. Whether he had candidly expressed his thoughts about the actual representation of Ireland, I don't know; but it was plain that he had not much enjoyed the interview. O'Connell looked very well: the levee was crowded: O'Connell was surrounded by ardent patriots: the junior O'Connell had led Patrick up to his father with particular kindness. Still, there was no enthusiasm in the report; and the next letter showed the reason why. Patrick could not understand O'Connell at all. It was certain that Dan remembered him; and he could not have forgotten the encouragement he gave him to write on behalf of his country; yet now he was cold, even repellent in his manner; and he tried to pretend that he did not know who Patrick was. What could this mean?
