Than the gentleman above named, there is nobody, in the whole circle of my acquaintance, whom I have more attentively studied, yet of whom I have less real knowledge, beneath the surface which it pleases him to present. Being anxious to discover who and what he really is, and how connected with me, and what are to be the results to him and to myself of the joint interest which, without any choice on my part, seems to be permanently established between us, and incited, furthermore, by the propensities of a student of human nature, though doubtful whether Monsieur du Miroir have aught of humanity but the figure — I have determined to place a few of his remarkable points before the public, hoping to be favored with some clew to the explanation of his character. Nor let the reader condemn any part of the narrative as frivolous, since a subject of such grave reflection diffuses its importance through the minutest particulars; and there is no judging beforehand what odd little circumstance may do the office of a blind man’s dog among the perplexities of this dark investigation; and however extraordinary, marvellous, preternatural, and utterly incredible some of the meditated disclosures may appear, I pledge my honor to maintain as sacred a regard to fact as if my testimony were given on oath and involved the dearest interests of the personage in question. Not that there is matter for a criminal accusation against Monsieur du Miroir, nor am I the man to bring it forward if there were. The chief that I complain of is his impenetrable mystery, which is no better than nonsense if it conceal anything good, and much worse in the contrary case.

But, if undue partialities could be supposed to influence me, Monsieur du Miroir might hope to profit rather than to suffer by them, for in the whole of our long intercourse we have seldom had the slightest disagreement; and, moreover, there are reasons for supposing him a near relative of mine, and consequently entitled to the best word that I can give him. He bears indisputably a strong personal resemblance to myself, and generally puts on mourning at the funerals of the family. On the other hand, his name would indicate a French descent; in which case, infinitely preferring that my blood should flow from a bold British and pure Puritan source, I beg leave to disclaim all kindred with Monsieur du Miroir. Some genealogists trace his origin to Spain, and dub him a knight of the order of the CABALLEROS DE LOS ESPEJOZ, one of whom was overthrown by Don Quixote. But what says Monsieur du Miroir himself of his paternity and his fatherland? Not a word did he ever say about the matter; and herein, perhaps, lies one of his most especial reasons for maintaining such a vexatious mystery, that he lacks the faculty of speech to expound it. His lips are sometimes seen to move; his eyes and countenance are alive with shifting expression, as if corresponding by visible hieroglyphics to his modulated breath; and anon he will seem to pause with as satisfied an air as if he had been talking excellent sense. Good sense or bad, Monsieur du Miroir is the sole judge of his own conversational powers, never having whispered so much as a syllable that reached the ears of any other auditor. Is he really dumb? or is all the world deaf? or is it merely a piece of my friend’s waggery, meant for nothing but to make fools of us? If so, he has the joke all to himself.

This dumb devil which possesses Monsieur do Miroir is, I am persuaded, the sole reason that he does not make me the most flattering protestations of friendship. In many particulars — indeed, as to all his cognizable and not preternatural points, except that, once in a great while, I speak a word or two — there exists the greatest apparent sympathy between us. Such is his confidence in my taste that he goes astray from the general fashion and copies all his dresses after mine. I never try on a new garment without expecting to meet, Monsieur du Miroir in one of the same pattern. He has duplicates of all my waistcoats and cravats, shirt-bosoms of precisely a similar plait, and an old coat for private wear, manufactured, I suspect, by a Chinese tailor, in exact imitation of a beloved old coat of mine, with a facsimile, stitch by stitch, of a patch upon the elbow. In truth, the singular and minute coincidences that occur, both in the accidents of the passing day and the serious events of our lives, remind me of those doubtful legends of lovers, or twin children, twins of fate, who have lived, enjoyed, suffered, and died in unison, each faithfully repeating the last tremor of the other’s breath, though separated by vast tracts of sea and land. Strange to say, my incommodities belong equally to my companion, though the burden is nowise alleviated by his participation. The other morning, after a night of torment from the toothache, I met Monsieur du Miroir with such a swollen anguish in his cheek that my own pangs were redoubled, as were also his, if I might judge by a fresh contortion of his visage. All the inequalities of my spirits are communicated to him, causing the unfortunate Monsieur du Miroir to mope and scowl through a whole summer’s day, or to laugh as long, for no better reason than the gay or gloomy crotchets of my brain. Once we were joint sufferers of a three months’ sickness, and met like mutual ghosts in the first days of convalescence. Whenever I have been in love, Monsieur du Miroir has looked passionate and tender; and never did my mistress discard me, but this too susceptible gentleman grew lackadaisical. His temper, also, rises to blood heat, fever heat, or boiling-water beat, according to the measure of any wrong which might seem to have fallen entirely on myself. I have sometimes been calmed down by the sight of my own inordinate wrath depicted on his frowning brow. Yet, however prompt in taking up my quarrels, I cannot call to mind that he ever struck a downright blow in my behalf; nor, in fact, do I perceive that any real and tangible good has resulted from his constant interference in my affairs; so that, in my distrustful moods, I am apt to suspect Monsieur du Miroir’s sympathy to be mere outward show, not a whit better nor worse than other people’s sympathy. Nevertheless, as mortal man must have something in the guise of sympathy — and whether the true metal, or merely copper-washed, is of less moment — I choose rather to content myself with Monsieur du Miroir’s, such as it is, than to seek the sterling coin, and perhaps miss even the counterfeit.

In my age of vanities I have often seen him in the ballroom, and might again were I to seek him there. We have encountered each other at the Tremont Theatre, where, however, he took his seat neither in the dress-circle, pit, nor upper regions, nor threw a single glance at the stage, though the brightest star, even Fanny Kemble herself, might be culminating there. No; this whimsical friend of mine chose to linger in the saloon, near one of the large looking-glasses which throw back their pictures of the illuminated room. He is so full of these unaccountable eccentricities that I never like to notice Monsieur du Miroir, nor to acknowledge the slightest connection with him, in places of public resort. He, however, has no scruple about claiming my acquaintance, even when his common-sense, if he had any, might teach him that I would as willingly exchange a nod with the Old Nick. It was but the other day that he got into a large brass kettle at the entrance of a hardware-store, and thrust his head, the moment afterwards, into a bright, new warming-pan, whence he gave me a most merciless look of recognition. He smiled, and so did I; but these childish tricks make decent people rather shy of Monsieur du Miroir, and subject him to more dead cuts than any other gentleman in town.

One of this singular person’s most remarkable peculiarities is his fondness for water, wherein he excels any temperance man whatever. His pleasure, it must be owned, is not so much to drink it (in which respect a very moderate quantity will answer his occasions) as to souse himself over head and ears wherever he may meet with it. Perhaps he is a merman, or born of a mermaid’s marriage with a mortal, and thus amphibious by hereditary right, like the children which the old river deities, or nymphs of fountains, gave to earthly love. When no cleaner bathing-place happened to be at hand, I have seen the foolish fellow in a horse-pond. Some times he refreshes himself in the trough of a town-pump, without caring what the people think about him. Often, while carefully picking my way along the street after a heavy shower, I have been scandalized to see Monsieur du Miroir, in full dress, paddling from one mud-puddle to another, and plunging into the filthy depths of each. Seldom have I peeped into a well without discerning this ridiculous gentleman at the bottom, whence he gazes up, as through a long telescopic tube, and probably makes discoveries among the stars by daylight. Wandering along lonesome paths or in pathless forests, when I have come to virgin fountains of which it would have been pleasant to deem myself the first discoverer, I have started to find Monsieur du Miroir there before me. The solitude seemed lonelier for his presence. I have leaned from a precipice that frowns over Lake George, which the French call nature’s font of sacramental water, and used it in their log-churches here and their cathedrals beyond the sea, and seen him far below in that pure element. At Niagara, too, where I would gladly have forgotten both myself and him, I could not help observing my companion in the smooth water on the very verge of the cataract just above the Table Rock. Were I to reach the sources of the Nile, I should expect to meet him there. Unless he be another Ladurlad, whose garments the depth of ocean could not moisten, it is difficult to conceive how he keeps himself in any decent pickle; though I am bound to confess that his clothes seem always as dry and comfortable as my own. But, as a friend, I could wish that he would not so often expose himself in liquor.

All that I have hitherto related may be classed among those little personal oddities which agreeably diversify the surface of society, and, though they may sometimes annoy us, yet keep our daily intercourse fresher and livelier than if they were done away. By an occasional hint, however, I have endeavored to pave the way for stranger things to come, which, had they been disclosed at once, Monsieur du Miroir might have been deemed a shadow, and myself a person of no veracity, and this truthful history a fabulous legend. But, now that the reader knows me worthy of his confidence, I will begin to make him stare.

To speak frankly, then, I could bring the most astounding proofs that Monsieur du Miroir is at least a conjurer, if not one of that unearthly tribe with whom conjurers deal. He has inscrutable methods of conveying himself from place to place with the rapidity of the swiftest steamboat or rail-car. Brick walls and oaken doors and iron bolts are no impediment to his passage. Here in my chamber, for instance, as the evening deepens into night, I sit alone — the key turned and withdrawn from the lock, the keyhole stuffed with paper to keep out a peevish little blast of wind. Yet, lonely as I seem, were I to lift one of the lamps and step five paces eastward, Monsieur du Miroir would be sure to meet me with a lamp also in his hand; and were I to take the stage-coach tomorrow, without giving him the least hint of my design, and post onward till the week’s end, at whatever hotel I might find myself I should expect to share my private apartment with this inevitable Monsieur du Miroir. Or, out of a mere wayward fantasy, were I to go, by moonlight, and stand beside the stone Pout of the Shaker Spring at Canterbury, Monsieur du Miroir would set forth on the same fool’s errand, and would not fail to meet me there. Shall I heighten the reader’s wonder? While writing these latter sentences, I happened to glance towards the large, round globe of one off the b............
