Collected Works of Poe Part 7

"In that which I now propose, we will discard the interior points of this tragedy, and concentrate our attention upon its outskirts. Not the least usual error, in investigations such as this, is the limiting of inquiry to the immediate, with total disregard of the collateral or circ.u.mstantial events. It is the mal-practice of the courts to confine evidence and discussion to the bounds of apparent relevancy. Yet experience has shown, and a true philosophy will always show, that a vast, perhaps the larger portion of truth, arises from the seemingly irrelevant. It is through the spirit of this principle, if not precisely through its letter, that modern science has resolved to calculate upon the unforeseen. But perhaps you do not comprehend me. The history of human knowledge has so uninterruptedly shown that to collateral, or incidental, or accidental events we are indebted for the most numerous and most valuable discoveries, that it has at length become necessary, in any prospective view of improvement, to make not only large, but the largest allowances for inventions that shall arise by chance, and quite out of the range of ordinary expectation. It is no longer philosophical to base, upon what has been, a vision of what is to be. Accident is admitted as a portion of the substructure. We make chance a matter of absolute calculation. We subject the unlooked for and unimagined, to the mathematical _formulae_ of the schools.

"I repeat that it is no more than fact, that the larger portion of all truth has sprung from the collateral; and it is but in accordance with the spirit of the principle involved in this fact, that I would divert inquiry, in the present case, from the trodden and hitherto unfruitful ground of the event itself, to the contemporary circ.u.mstances which surround it. While you ascertain the validity of the affidavits, I will examine the newspapers more generally than you have as yet done. So far, we have only reconnoitred the field of investigation; but it will be strange indeed if a comprehensive survey, such as I propose, of the public prints, will not afford us some minute points which shall establish a direction for inquiry."

In pursuance of Dupin's suggestion, I made scrupulous examination of the affair of the affidavits. The result was a firm conviction of their validity, and of the consequent innocence of St. Eustache. In the mean time my friend occupied himself, with what seemed to me a minuteness altogether objectless, in a scrutiny of the various newspaper files. At the end of a week he placed before me the following extracts: "About three years and a half ago, a disturbance very similar to the present, was caused by the disappearance of this same Marie Roget, from the parfumerie of Monsieur Le Blanc, in the Palais Royal. At the end of a week, however, she re-appeared at her customary comptoir, as well as ever, with the exception of a slight paleness not altogether usual. It was given out by Monsieur Le Blanc and her mother, that she had merely been on a visit to some friend in the country; and the affair was speedily hushed up. We presume that the present absence is a freak of the same nature, and that, at the expiration of a week, or perhaps of a month, we shall have her among us again." - Evening Paper - Monday June 23. {*17} "An evening journal of yesterday, refers to a former mysterious disappearance of Mademoiselle Roget. It is well known that, during the week of her absence from Le Blanc's parfumerie, she was in the company of a young naval officer, much noted for his debaucheries. A quarrel, it is supposed, providentially led to her return home. We have the name of the Lothario in question, who is, at present, stationed in Paris, but, for obvious reasons, forbear to make it public." - Le Mercurie - Tuesday Morning, June 24. {*18} "An outrage of the most atrocious character was perpetrated near this city the day before yesterday. A gentleman, with his wife and daughter, engaged, about dusk, the services of six young men, who were idly rowing a boat to and fro near the banks of the Seine, to convey him across the river. Upon reaching the opposite sh.o.r.e, the three pa.s.sengers stepped out, and had proceeded so far as to be beyond the view of the boat, when the daughter discovered that she had left in it her parasol. She returned for it, was seized by the gang, carried out into the stream, gagged, brutally treated, and finally taken to the sh.o.r.e at a point not far from that at which she had originally entered the boat with her parents. The villains have escaped for the time, but the police are upon their trail, and some of them will soon be taken." - Morning Paper - June 25. {*19} "We have received one or two communications, the object of which is to fasten the crime of the late atrocity upon Mennais; {*20} but as this gentleman has been fully exonerated by a loyal inquiry, and as the arguments of our several correspondents appear to be more zealous than profound, we do not think it advisable to make them public." - Morning Paper - June 28. {*21} "We have received several forcibly written communications, apparently from various sources, and which go far to render it a matter of certainty that the unfortunate Marie Roget has become a victim of one of the numerous bands of blackguards which infest the vicinity of the city upon Sunday. Our own opinion is decidedly in favor of this supposition. We shall endeavor to make room for some of these arguments hereafter." - Evening Paper - Tuesday, June 31. {*22} "On Monday, one of the bargemen connected with the revenue service, saw a empty boat floating down the Seine. Sails were lying in the bottom of the boat. The bargeman towed it under the barge office. The next morning it was taken from thence, without the knowledge of any of the officers. The rudder is now at the barge office." - Le Diligence - Thursday, June 26. -- Upon reading these various extracts, they not only seemed to me irrelevant, but I could perceive no mode in which any one of them could be brought to bear upon the matter in hand. I waited for some explanation from Dupin.

"It is not my present design," he said, "to dwell upon the first and second of those extracts. I have copied them chiefly to show you the extreme remissness of the police, who, as far as I can understand from the Prefect, have not troubled themselves, in any respect, with an examination of the naval officer alluded to. Yet it is mere folly to say that between the first and second disappearance of Marie, there is no _supposable_ connection. Let us admit the first elopement to have resulted in a quarrel between the lovers, and the return home of the betrayed. We are now prepared to view a second elopement (if we know that an elopement has again taken place) as indicating a renewal of the betrayer's advances, rather than as the result of new proposals by a second individual - we are prepared to regard it as a 'making up' of the old amour, rather than as the commencement of a new one. The chances are ten to one, that he who had once eloped with Marie, would again propose an elopement, rather than that she to whom proposals of elopement had been made by one individual, should have them made to her by another. And here let me call your attention to the fact, that the time elapsing between the first ascertained, and the second supposed elopement, is a few months more than the general period of the cruises of our men-of-war. Had the lover been interrupted in his first villany by the necessity of departure to sea, and had he seized the first moment of his return to renew the base designs not yet altogether accomplished - or not yet altogether accomplished by _him?_ Of all these things we know nothing.

"You will say, however, that, in the second instance, there was no elopement as imagined. Certainly not - but are we prepared to say that there was not the frustrated design? Beyond St. Eustache, and perhaps Beauvais, we find no recognized, no open, no honorable suitors of Marie. Of none other is there any thing said. Who, then, is the secret lover, of whom the relatives (at least most of them) know nothing, but whom Marie meets upon the morning of Sunday, and who is so deeply in her confidence, that she hesitates not to remain with him until the shades of the evening descend, amid the solitary groves of the Barriere du Roule? Who is that secret lover, I ask, of whom, at least, most of the relatives know nothing? And what means the singular prophecy of Madame Roget on the morning of Marie's departure? -- 'I fear that I shall never see Marie again.'

"But if we cannot imagine Madame Roget privy to the design of elopement, may we not at least suppose this design entertained by the girl? Upon quitting home, she gave it to be understood that she was about to visit her aunt in the Rue des Dromes and St. Eustache was requested to call for her at dark. Now, at first glance, this fact strongly militates against my suggestion; - but let us reflect. That she did meet some companion, and proceed with him across the river, reaching the Barriere du Roule at so late an hour as three o'clock in the afternoon, is known. But in consenting so to accompany this individual, (_for whatever purpose -- to her mother known or unknown,_) she must have thought of her expressed intention when leaving home, and of the surprise and suspicion aroused in the bosom of her affianced suitor, St. Eustache, when, calling for her, at the hour appointed, in the Rue des Dromes, he should find that she had not been there, and when, moreover, upon returning to the pension with this alarming intelligence, he should become aware of her continued absence from home. She must have thought of these things, I say. She must have foreseen the chagrin of St. Eustache, the suspicion of all. She could not have thought of returning to brave this suspicion; but the suspicion becomes a point of trivial importance to her, if we suppose her not intending to return.

"We may imagine her thinking thus - 'I am to meet a certain person for the purpose of elopement, or for certain other purposes known only to myself. It is necessary that there be no chance of interruption - there must be sufficient time given us to elude pursuit - I will give it to be understood that I shall visit and spend the day with my aunt at the Rue des Dromes - I well tell St. Eustache not to call for me until dark - in this way, my absence from home for the longest possible period, without causing suspicion or anxiety, will be accounted for, and I shall gain more time than in any other manner. If I bid St. Eustache call for me at dark, he will be sure not to call before; but, if I wholly neglect to bid him call, my time for escape will be diminished, since it will be expected that I return the earlier, and my absence will the sooner excite anxiety. Now, if it were my design to return at all - if I had in contemplation merely a stroll with the individual in question - it would not be my policy to bid St. Eustache call; for, calling, he will be sure to ascertain that I have played him false - a fact of which I might keep him for ever in ignorance, by leaving home without notifying him of my intention, by returning before dark, and by then stating that I had been to visit my aunt in the Rue des Dromes. But, as it is my design never to return - or not for some weeks - or not until certain concealments are effected - the gaining of time is the only point about which I need give myself any concern.'

"You have observed, in your notes, that the most general opinion in relation to this sad affair is, and was from the first, that the girl had been the victim of a gang of blackguards. Now, the popular opinion, under certain conditions, is not to be disregarded. When arising of itself -- when manifesting itself in a strictly spontaneous manner -- we should look upon it as a.n.a.logous with that _intuition_ which is the idiosyncrasy of the individual man of genius. In ninety-nine cases from the hundred I would abide by its decision. But it is important that we find no palpable traces of _suggestion_. The opinion must be rigorously _the public's own_; and the distinction is often exceedingly difficult to perceive and to maintain. In the present instance, it appears to me that this 'public opinion' in respect to a gang, has been superinduced by the collateral event which is detailed in the third of my extracts. All Paris is excited by the discovered corpse of Marie, a girl young, beautiful and notorious. This corpse is found, bearing marks of violence, and floating in the river. But it is now made known that, at the very period, or about the very period, in which it is supposed that the girl was a.s.sa.s.sinated, an outrage similar in nature to that endured by the deceased, although less in extent, was perpetuated, by a gang of young ruffians, upon the person of a second young female. Is it wonderful that the one known atrocity should influence the popular judgment in regard to the other unknown? This judgment awaited direction, and the known outrage seemed so opportunely to afford it! Marie, too, was found in the river; and upon this very river was this known outrage committed. The connexion of the two events had about it so much of the palpable, that the true wonder would have been a failure of the populace to appreciate and to seize it. But, in fact, the one atrocity, known to be so committed, is, if any thing, evidence that the other, committed at a time nearly coincident, was not so committed. It would have been a miracle indeed, if, while a gang of ruffians were perpetrating, at a given locality, a most unheard-of wrong, there should have been another similar gang, in a similar locality, in the same city, under the same circ.u.mstances, with the same means and appliances, engaged in a wrong of precisely the same aspect, at precisely the same period of time! Yet in what, if not in this marvellous train of coincidence, does the accidentally suggested opinion of the populace call upon us to believe?

"Before proceeding farther, let us consider the supposed scene of the a.s.sa.s.sination, in the thicket at the Barriere du Roule. This thicket, although dense, was in the close vicinity of a public road. Within were three or four large stones, forming a kind of seat with a back and footstool. On the upper stone was discovered a white petticoat; on the second, a silk scarf. A parasol, gloves, and a pocket-handkerchief, were also here found. The handkerchief bore the name, 'Marie Roget.' Fragments of dress were seen on the branches around. The earth was trampled, the bushes were broken, and there was every evidence of a violent struggle.

"Notwithstanding the acclamation with which the discovery of this thicket was received by the press, and the unanimity with which it was supposed to indicate the precise scene of the outrage, it must be admitted that there was some very good reason for doubt. That it was the scene, I may or I may not believe - but there was excellent reason for doubt. Had the true scene been, as Le Commerciel suggested, in the neighborhood of the Rue Pavee St. Andree, the perpetrators of the crime, supposing them still resident in Paris, would naturally have been stricken with terror at the public attention thus acutely directed into the proper channel; and, in certain cla.s.ses of minds, there would have arisen, at once, a sense of the necessity of some exertion to redivert this attention. And thus, the thicket of the Barriere du Roule having been already suspected, the idea of placing the articles where they were found, might have been naturally entertained. There is no real evidence, although Le Soleil so supposes, that the articles discovered had been more than a very few days in the thicket; while there is much circ.u.mstantial proof that they could not have remained there, without attracting attention, during the twenty days elapsing between the fatal Sunday and the afternoon upon which they were found by the boys. 'They were all _mildewed_down hard,' says Le Soleil, adopting the opinions of its predecessors, 'with the action of the rain, and stuck together from _mildew_. The gra.s.s had grown around and over some of them. The silk of the parasol was strong, but the threads of it were run together within. The upper part, where it bad been doubled and folded, was all _mildewed_ and rotten, and tore on being opened.' In respect to the gra.s.s having '.grown around and over some of them,' it is obvious that the fact could only have been ascertained from the words, and thus from the recollections, of two small boys; for these boys removed the articles and took them home before they had been seen by a third party. But gra.s.s will grow, especially in warm and damp weather, (such as was that of the period of the murder,) as much as two or three inches in a single day. A parasol lying upon a newly turfed ground, might, in a single week, be entirely concealed from sight by the upspringing gra.s.s. And touching that mildew upon which the editor of Le Soleil so pertinaciously insists, that he employs the word no less than three times in the brief paragraph just quoted, is be really unaware of the nature of this mildew? Is he to be told that it is one of the many cla.s.ses of fungus, of which the most ordinary feature is its upspringing and decadence within twenty-four hours?

"Thus we see, at a glance, that what has been most triumphantly adduced in support of the idea that the articles bad been 'for at least three or four weeks' in the thicket, is most absurdly null as regards any evidence of that fact. On the other hand, it is exceedingly difficult to believe that these articles could have remained in the thicket specified, for a longer period than a single week - for a longer period than from one Sunday to the next. Those who know any thing of the vicinity of Paris, know the extreme difficulty of finding seclusion unless at a great distance from its suburbs. Such a thing as an unexplored, or even an unfrequently visited recess, amid its woods or groves, is not for a moment to be imagined. Let any one who, being at heart a lover of nature, is yet chained by duty to the dust and heat of this great metropolis - let any such one attempt, even during the weekdays, to slake his thirst for solitude amid the scenes of natural loveliness which immediately surround us. At every second step, he will find the growing charm dispelled by the voice and personal intrusion of some ruffian or party of carousing blackguards. He will seek privacy amid the densest foliage, all in vain. Here are the very nooks where the unwashed most abound - here are the temples most desecrate. With sickness of the heart the wanderer will flee back to the polluted Paris as to a less odious because less incongruous sink of pollution. But if the vicinity of the city is so beset during the working days of the week, how much more so on the Sabbath! It is now especially that, released from the claims of labor, or deprived of the customary opportunities of crime, the town blackguard seeks the precincts of the town, not through love of the rural, which in his heart he despises, but by way of escape from the restraints and conventionalities of society. He desires less the fresh air and the green trees, than the utter license of the country. Here, at the road-side inn, or beneath the foliage of the woods, he indulges, unchecked by any eye except those of his boon companions, in all the mad excess of a counterfeit hilarity - the joint offspring of liberty and of rum. I say nothing more than what must be obvious to every dispa.s.sionate observer, when I repeat that the circ.u.mstance of the articles in question having remained undiscovered, for a longer period - than from one Sunday to another, in any thicket in the immediate neighborhood of Paris, is to be looked upon as little less than miraculous.

"But there are not wanting other grounds for the suspicion that the articles were placed in the thicket with the view of diverting attention from the real scene of the outrage. And, first, let me direct your notice to the date of the discovery of the articles. Collate this with the date of the fifth extract made by myself from the newspapers. You will find that the discovery followed, almost immediately, the urgent communications sent to the evening paper. These communications, although various and apparently from various sources, tended all to the same point - viz., the directing of attention to a gang as the perpetrators of the outrage, and to the neighborhood of the Barriere du Roule as its scene. Now here, of course, the suspicion is not that, in consequence of these communications, or of the public attention by them directed, the articles were found by the boys; but the suspicion might and may well have been, that the articles were not before found by the boys, for the reason that the articles had not before been in the thicket; having been deposited there only at so late a period as at the date, or shortly prior to the date of the communications by the guilty authors of these communications themselves.

"This thicket was a singular - an exceedingly singular one. It was unusually dense. Within its naturally walled enclosure were three extraordinary stones, forming a seat with a back and footstool. And this thicket, so full of a natural art, was in the immediate vicinity, within a few rods, of the dwelling of Madame Deluc, whose boys were in the habit of closely examining the shrubberies about them in search of the bark of the sa.s.safras. Would it be a rash wager - a wager of one thousand to one -- that a day never pa.s.sed over the heads of these boys without finding at least one of them ensconced in the umbrageous hall, and enthroned upon its natural throne? Those who would hesitate at such a wager, have either never been boys themselves, or have forgotten the boyish nature. I repeat -- it is exceedingly hard to comprehend how the articles could have remained in this thicket undiscovered, for a longer period than one or two days; and that thus there is good ground for suspicion, in spite of the dogmatic ignorance of Le Soleil, that they were, at a comparatively late date, deposited where found.

"But there are still other and stronger reasons for believing them so deposited, than any which I have as yet urged. And, now, let me beg your notice to the highly artificial arrangement of the articles. On the upper stone lay a white petticoat; on the second a silk scarf; scattered around, were a parasol, gloves, and a pocket-handkerchief bearing the name, 'Marie Roget.' Here is just such an arrangement as would naturally be made by a not over-acute person wis.h.i.+ng to dispose the articles naturally. But it is by no means a really natural arrangement. I should rather have looked to see the things all lying on the ground and trampled under foot. In the narrow limits of that bower, it would have been scarcely possible that the petticoat and scarf should have retained a position upon the stones, when subjected to the brus.h.i.+ng to and fro of many struggling persons. 'There was evidence,' it is said, 'of a struggle; and the earth was trampled, the bushes were broken,' - but the petticoat and the scarf are found deposited as if upon shelves. 'The pieces of the frock torn out by the bushes were about three inches wide and six inches long. One part was the hem of the frock and it had been mended. They looked like strips torn off.' Here, inadvertently, Le Soleil has employed an exceedingly suspicious phrase. The pieces, as described, do indeed 'look like strips torn off;' but purposely and by hand. It is one of the rarest of accidents that a piece is 'torn off,' from any garment such as is now in question, by the agency of a thorn. From the very nature of such fabrics, a thorn or nail becoming entangled in them, tears them rectangularly - divides them into two longitudinal rents, at right angles with each other, and meeting at an apex where the thorn enters - but it is scarcely possible to conceive the piece 'torn off.' I never so knew it, nor did you. To tear a piece off from such fabric, two distinct forces, in different directions, will be, in almost every case, required. If there be two edges to the fabric - if, for example, it be a pocket- handkerchief, and it is desired to tear from it a slip, then, and then only, will the one force serve the purpose. But in the present case the question is of a dress, presenting but one edge. To tear a piece from the interior, where no edge is presented, could only be effected by a miracle through the agency of thorns, and no one thorn could accomplish it. But, even where an edge is presented, two thorns will be necessary, operating, the one in two distinct directions, and the other in one. And this in the supposition that the edge is unhemmed. If hemmed, the matter is nearly out of the question. We thus see the numerous and great obstacles in the way of pieces being 'torn off' through the simple agency of 'thorns;' yet we are required to believe not only that one piece but that many have been so torn. 'And one part,' too, 'was the hem of the frock!' Another piece was 'part of the skirt, not the hem,' - that is to say, was torn completely out through the agency of thorns, from the uncaged interior of the dress! These, I say, are things which one may well be pardoned for disbelieving; yet, taken collectedly, they form, perhaps, less of reasonable ground for suspicion, than the one startling circ.u.mstance of the articles' having been left in this thicket at all, by any murderers who had enough precaution to think of removing the corpse. You will not have apprehended me rightly, however, if you suppose it my design to deny this thicket as the scene of the outrage. There might have been a wrong here, or, more possibly, an accident at Madame Deluc's. But, in fact, this is a point of minor importance. We are not engaged in an attempt to discover the scene, but to produce the perpetrators of the murder. What I have adduced, notwithstanding the minuteness with which I have adduced it, has been with the view, first, to show the folly of the positive and headlong a.s.sertions of Le Soleil, but secondly and chiefly, to bring you, by the most natural route, to a further contemplation of the doubt whether this a.s.sa.s.sination has, or has not been, the work of a gang.

"We will resume this question by mere allusion to the revolting details of the surgeon examined at the inquest. It is only necessary to say that is published inferences, in regard to the number of ruffians, have been properly ridiculed as unjust and totally baseless, by all the reputable anatomists of Paris. Not that the matter might not have been as inferred, but that there was no ground for the inference: - was there not much for another?

"Let us reflect now upon 'the traces of a struggle;' and let me ask what these traces have been supposed to demonstrate. A gang. But do they not rather demonstrate the absence of a gang? What struggle could have taken place - what struggle so violent and so enduring as to have left its 'traces' in all directions - between a weak and defenceless girl and the gang of ruffians imagined? The silent grasp of a few rough arms and all would have been over. The victim must have been absolutely pa.s.sive at their will. You will here bear in mind that the arguments urged against the thicket as the scene, are applicable in chief part, only against it as the scene of an outrage committed by more than a single individual. If we imagine but one violator, we can conceive, and thus only conceive, the struggle of so violent and so obstinate a nature as to have left the 'traces' apparent.

"And again. I have already mentioned the suspicion to be excited by the fact that the articles in question were suffered to remain at all in the thicket where discovered. It seems almost impossible that these evidences of guilt should have been accidentally left where found. There was sufficient presence of mind (it is supposed) to remove the corpse; and yet a more positive evidence than the corpse itself (whose features might have been quickly obliterated by decay,) is allowed to lie conspicuously in the scene of the outrage - I allude to the handkerchief with the name of the deceased. If this was accident, it was not the accident of a gang. We can imagine it only the accident of an individual. Let us see. An individual has committed the murder. He is alone with the ghost of the departed. He is appalled by what lies motionless before him. The fury of his pa.s.sion is over, and there is abundant room in his heart for the natural awe of the deed. His is none of that confidence which the presence of numbers inevitably inspires. He is alone with the dead. He trembles and is bewildered. Yet there is a necessity for disposing of the corpse. He bears it to the river, but leaves behind him the other evidences of guilt; for it is difficult, if not impossible to carry all the burthen at once, and it will be easy to return for what is left. But in his toilsome journey to the water his fears redouble within him. The sounds of life encompa.s.s his path. A dozen times he hears or fancies the step of an observer. Even the very lights from the city bewilder him. Yet, in time and by long and frequent pauses of deep agony, he reaches the river's brink, and disposes of his ghastly charge - perhaps through the medium of a boat. But now what treasure does the world hold - what threat of vengeance could it hold out - which would have power to urge the return of that lonely murderer over that toilsome and perilous path, to the thicket and its blood chilling recollections? He returns not, let the consequences be what they may. He could not return if he would. His sole thought is immediate escape. He turns his back forever upon those dreadful shrubberies and flees as from the wrath to come.

"But how with a gang? Their number would have inspired them with confidence; if, indeed confidence is ever wanting in the breast of the arrant blackguard; and of arrant blackguards alone are the supposed gangs ever const.i.tuted. Their number, I say, would have prevented the bewildering and unreasoning terror which I have imagined to paralyze the single man. Could we suppose an oversight in one, or two, or three, this oversight would have been remedied by a fourth. They would have left nothing behind them; for their number would have enabled them to carry all at once. There would have been no need of return.

"Consider now the circ.u.mstance that in the outer garment of the corpse when found, 'a slip, about a foot wide had been torn upward from the bottom hem to the waist wound three times round the waist, and secured by a sort of hitch in the back.' This was done with the obvious design of affording a handle by which to carry the body. But would any number of men hare dreamed of resorting to such an expedient? To three or four, the limbs of the corpse would have afforded not only a sufficient, but the best possible hold. The device is that of a single individual; and this brings us to the fact that 'between the thicket and the river, the rails of the fences were found taken down, and the ground bore evident traces of some heavy burden having been dragged along it!' But would a number of men have put themselves to the superfluous trouble of taking down a fence, for the purpose of dragging through it a corpse which they might have lifted over any fence in an instant? Would a number of men have so dragged a corpse at all as to have left evident traces of the dragging?

"And here we must refer to an observation of Le Commerciel; an observation upon which I have already, in some measure, commented. 'A piece,' says this journal, 'of one of the unfortunate girl's petticoats was torn out and tied under her chin, and around the back of her head, probably to prevent screams. This was done by fellows who had no pocket-handkerchiefs.'

"I have before suggested that a genuine blackguard is never without a pocket-handkerchief. But it is not to this fact that I now especially advert. That it was not through want of a handkerchief for the purpose imagined by Le Commerciel, that this bandage was employed, is rendered apparent by the handkerchief left in the thicket; and that the object was not 'to prevent screams' appears, also, from the bandage having been employed in preference to what would so much better have answered the purpose. But the language of the evidence speaks of the strip in question as 'found around the neck, fitting loosely, and secured with a hard knot.' These words are sufficiently vague, but differ materially from those of Le Commerciel. The slip was eighteen inches wide, and therefore, although of muslin, would form a strong band when folded or rumpled longitudinally. And thus rumpled it was discovered. My inference is this. The solitary murderer, having borne the corpse, for some distance, (whether from the thicket or elsewhere) by means of the bandage hitched around its middle, found the weight, in this mode of procedure, too much for his strength. He resolved to drag the burthen - the evidence goes to show that it wasdragged. With this object in view, it became necessary to attach something like a rope to one of the extremities. It could be best attached about the neck, where the head would prevent its slipping off. And, now, the murderer bethought him, unquestionably, of the bandage about the loins. He would have used this, but for its volution about the corpse, the hitch which embarra.s.sed it, and the reflection that it had not been 'torn off' from the garment. It was easier to tear a new slip from the petticoat. He tore it, made it fast about the neck, and so dragged his victim to the brink of the river. That this 'bandage,' only attainable with trouble and delay, and but imperfectly answering its purpose - that this bandage was employed at all, demonstrates that the necessity for its employment sprang from circ.u.mstances arising at a period when the handkerchief was no longer attainable -- that is to say, arising, as we have imagined, after quitting the thicket, (if the thicket it was), and on the road between the thicket and the river.

"But the evidence, you will say, of Madame Deluc, (!) points especially to the presence of a gang, in the vicinity of the thicket, at or about the epoch of the murder. This I grant. I doubt if there were not a dozen gangs, such as described by Madame Deluc, in and about the vicinity of the Barriere du Roule at or about the period of this tragedy. But the gang which has drawn upon itself the pointed animadversion, although the somewhat tardy and very suspicious evidence of Madame Deluc, is the only gang which is represented by that honest and scrupulous old lady as having eaten her cakes and swallowed her brandy, without putting themselves to the trouble of making her payment. Et hinc illae irae?

"But what is the precise evidence of Madame Deluc? 'A gang of miscreants made their appearance, behaved boisterously, ate and drank without making payment, followed in the route of the young man and girl, returned to the inn about dusk, and recrossed the river as if in great haste.'

"Now this 'great haste' very possibly seemed greater haste in the eyes of Madame Deluc, since she dwelt lingeringly and lamentingly upon her violated cakes and ale - cakes and ale for which she might still have entertained a faint hope of compensation. Why, otherwise, since it was about dusk, should she make a point of the haste? It is no cause for wonder, surely, that even a gang of blackguards should make haste to get home, when a wide river is to be crossed in small boats, when storm impends, and when night approaches.

"I say approaches; for the night had not yet arrived. It was only about dusk that the indecent haste of these 'miscreants' offended the sober eyes of Madame Deluc. But we are told that it was upon this very evening that Madame Deluc, as well as her eldest son, 'heard the screams of a female in the vicinity of the inn.' And in what words does Madame Deluc designate the period of the evening at which these screams were heard? 'It was soon after dark,' she says. But 'soon after dark,' is, at least, dark; and'about dusk' is as certainly daylight. Thus it is abundantly clear that the gang quitted the Barriere du Roule prior to the screams overheard (?) by Madame Deluc. And although, in all the many reports of the evidence, the relative expressions in question are distinctly and invariably employed just as I have employed them in this conversation with yourself, no notice whatever of the gross discrepancy has, as yet, been taken by any of the public journals, or by any of the Myrmidons of police.

"I shall add but one to the arguments against a gang; but this one has, to my own understanding at least, a weight altogether irresistible. Under the circ.u.mstances of large reward offered, and full pardon to any King's evidence, it is not to be imagined, for a moment, that some member of a gang of low ruffians, or of any body of men, would not long ago have betrayed his accomplices. Each one of a gang so placed, is not so much greedy of reward, or anxious for escape, as fearful of betrayal. He betrays eagerly and early that he may not himself be betrayed. That the secret has not been divulged, is the very best of proof that it is, in fact, a secret. The horrors of this dark deed are known only to one, or two, living human beings, and to G.o.d.

"Let us sum up now the meagre yet certain fruits of our long a.n.a.lysis. We have attained the idea either of a fatal accident under the roof of Madame Deluc, or of a murder perpetrated, in the thicket at the Barriere du Roule, by a lover, or at least by an intimate and secret a.s.sociate of the deceased. This a.s.sociate is of swarthy complexion. This complexion, the 'hitch' in the bandage, and the 'sailor's knot,' with which the bonnet-ribbon is tied, point to a seaman. His companions.h.i.+p with the deceased, a gay, but not an abject young girl, designates him as above the grade of the common sailor. Here the well written and urgent communications to the journals are much in the way of corroboration. The circ.u.mstance of the first elopement, as mentioned by Le Mercurie, tends to blend the idea of this seaman with that of the 'naval officer' who is first known to have led the unfortunate into crime.

"And here, most fitly, comes the consideration of the continued absence of him of the dark complexion. Let me pause to observe that the complexion of this man is dark and swarthy; it was no common swarthiness which const.i.tuted the sole point of remembrance, both as regards Valence and Madame Deluc. But why is this man absent? Was he murdered by the gang? If so, why are there only traces of the a.s.sa.s.sinated girl? The scene of the two outrages will naturally be supposed identical. And where is his corpse? The a.s.sa.s.sins would most probably have disposed of both in the same way. But it may be said that this man lives, and is deterred from making himself known, through dread of being charged with the murder. This consideration might be supposed to operate upon him now - at this late period - since it has been given in evidence that he was seen with Marie - but it would have had no force at the period of the deed. The first impulse of an innocent man would have been to announce the outrage, and to aid in identifying the ruffians. This policy would have suggested. He had been seen with the girl. He had crossed the river with her in an open ferry-boat. The denouncing of the a.s.sa.s.sins would have appeared, even to an idiot, the surest and sole means of relieving himself from suspicion. We cannot suppose him, on the night of the fatal Sunday, both innocent himself and incognizant of an outrage committed. Yet only under such circ.u.mstances is it possible to imagine that he would have failed, if alive, in the denouncement of the a.s.sa.s.sins.

"And what means are ours, of attaining the truth? We shall find these means multiplying and gathering distinctness as we proceed. Let us sift to the bottom this affair of the first elopement. Let us know the full history of 'the officer,' with his present circ.u.mstances, and his whereabouts at the precise period of the murder. Let us carefully compare with each other the various communications sent to the evening paper, in which the object was to inculpate a gang. This done, let us compare these communications, both as regards style and MS., with those sent to the morning paper, at a previous period, and insisting so vehemently upon the guilt of Mennais. And, all this done, let us again compare these various communications with the known MSS. of the officer. Let us endeavor to ascertain, by repeated questionings of Madame Deluc and her boys, as well as of the omnibus driver, Valence, something more of the personal appearance and bearing of the 'man of dark complexion.' Queries, skilfully directed, will not fail to elicit, from some of these parties, information on this particular point (or upon others) - information which the parties themselves may not even be aware of possessing. And let us now trace the boatpicked up by the bargeman on the morning of Monday the twenty-third of June, and which was removed from the barge-office, without the cognizance of the officer in attendance, and without the rudder, at some period prior to the discovery of the corpse. With a proper caution and perseverance we shall infallibly trace this boat; for not only can the bargeman who picked it up identify it, but the rudder is at hand. The rudder of a sail-boat would not have been abandoned, without inquiry, by one altogether at ease in heart. And here let me pause to insinuate a question. There was no advertis.e.m.e.nt of the picking up of this boat. It was silently taken to the barge-office, and as silently removed. But its owner or employer - how happened he, at so early a period as Tuesday morning, to be informed, without the agency of advertis.e.m.e.nt, of the locality of the boat taken up on Monday, unless we imagine some connexion with the navy - some personal permanent connexion leading to cognizance of its minute in interests - its petty local news?

"In speaking of the lonely a.s.sa.s.sin dragging his burden to the sh.o.r.e, I have already suggested the probability of his availing himself of a boat. Now we are to understand that Marie Roget was precipitated from a boat. This would naturally have been the case. The corpse could not have been trusted to the shallow waters of the sh.o.r.e. The peculiar marks on the back and shoulders of the victim tell of the bottom ribs of a boat. That the body was found without weight is also corroborative of the idea. If thrown from the sh.o.r.e a weight would have been attached. We can only account for its absence by supposing the murderer to have neglected the precaution of supplying himself with it before pus.h.i.+ng off. In the act of consigning the corpse to the water, he would unquestionably have noticed his oversight; but then no remedy would have been at hand. Any risk would have been preferred to a return to that accursed sh.o.r.e. Having rid himself of his ghastly charge, the murderer would have hastened to the city. There, at some obscure wharf, he would have leaped on land. But the boat - would he have secured it? He would have been in too great haste for such things as securing a boat. Moreover, in fastening it to the wharf, he would have felt as if securing evidence against himself. His natural thought would have been to cast from him, as far as possible, all that had held connection with his crime. He would not only have fled from the wharf, but he would not have permitted the boat to remain. a.s.suredly he would have cast it adrift. Let us pursue our fancies. - In the morning, the wretch is stricken with unutterable horror at finding that the boat has been picked up and detained at a locality which he is in the daily habit of frequenting - at a locality, perhaps, which his duty compels him to frequent. The next night, without daring to ask for the rudder, he removes it. Now where is that rudderless boat? Let it be one of our first purposes to discover. With the first glimpse we obtain of it, the dawn of our success shall begin. This boat shall guide us, with a rapidity which will surprise even ourselves, to him who employed it in the midnight of the fatal Sabbath. Corroboration will rise upon corroboration, and the murderer will be traced."

[For reasons which we shall not specify, but which to many readers will appear obvious, we have taken the liberty of here omitting, from the MSS. placed in our hands, such portion as details the following up of the apparently slight clew obtained by Dupin. We feel it advisable only to state, in brief, that the result desired was brought to pa.s.s; and that the Prefect fulfilled punctually, although with reluctance, the terms of his compact with the Chevalier. Mr. Poe's article concludes with the following words. - Eds. {*23}]

It will be understood that I speak of coincidences and no more. What I have said above upon this topic must suffice. In my own heart there dwells no faith in praeter-nature. That Nature and its G.o.d are two, no man who thinks, will deny. That the latter, creating the former, can, at will, control or modify it, is also unquestionable. I say "at will;" for the question is of will, and not, as the insanity of logic has a.s.sumed, of power. It is not that the Deity cannot modify his laws, but that we insult him in imagining a possible necessity for modification. In their origin these laws were fas.h.i.+oned to embrace all contingencies which could lie in the Future. With G.o.d all is Now.

I repeat, then, that I speak of these things only as of coincidences. And farther: in what I relate it will be seen that between the fate of the unhappy Mary Cecilia Rogers, so far as that fate is known, and the fate of one Marie Roget up to a certain epoch in her history, there has existed a parallel in the contemplation of whose wonderful exact.i.tude the reason becomes embarra.s.sed. I say all this will be seen. But let it not for a moment be supposed that, in proceeding with the sad narrative of Marie from the epoch just mentioned, and in tracing to its denouement the mystery which enshrouded her, it is my covert design to hint at an extension of the parallel, or even to suggest that the measures adopted in Paris for the discovery of the a.s.sa.s.sin of a grisette, or measures founded in any similar ratiocination, would produce any similar result.

For, in respect to the latter branch of the supposition, it should be considered that the most trifling variation in the facts of the two cases might give rise to the most important miscalculations, by diverting thoroughly the two courses of events; very much as, in arithmetic, an error which, in its own individuality, may be inappreciable, produces, at length, by dint of multiplication at all points of the process, a result enormously at variance with truth. And, in regard to the former branch, we must not fail to hold in view that the very Calculus of Probabilities to which I have referred, forbids all idea of the extension of the parallel: - forbids it with a positiveness strong and decided just in proportion as this parallel has already been long-drawn and exact. This is one of those anomalous propositions which, seemingly appealing to thought altogether apart from the mathematical, is yet one which only the mathematician can fully entertain. Nothing, for example, is more difficult than to convince the merely general reader that the fact of sixes having been thrown twice in succession by a player at dice, is sufficient cause for betting the largest odds that sixes will not be thrown in the third attempt. A suggestion to this effect is usually rejected by the intellect at once. It does not appear that the two throws which have been completed, and which lie now absolutely in the Past, can have influence upon the throw which exists only in the Future. The chance for throwing sixes seems to be precisely as it was at any ordinary time - that is to say, subject only to the influence of the various other throws which may be made by the dice. And this is a reflection which appears so exceedingly obvious that attempts to controvert it are received more frequently with a derisive smile than with anything like respectful attention. The error here involved - a gross error redolent of mischief - I cannot pretend to expose within the limits a.s.signed me at present; and with the philosophical it needs no exposure. It may be sufficient here to say that it forms one of an infinite series of mistakes which arise in the path or Reason through her propensity for seeking truth in detail.

FOOTNOTES--Marie Roget {*1} Upon the original publication of "Marie Roget," the foot-notes now appended were considered unnecessary; but the lapse of several years since the tragedy upon which the tale is based, renders it expedient to give them, and also to say a few words in explanation of the general design. A young girl, Mary Cecilia Rogers, was murdered in the vicinity of New York; and, although her death occasioned an intense and long-enduring excitement, the mystery attending it had remained unsolved at the period when the present paper was written and published (November, 1842). Herein, under pretence of relating the fate of a Parisian grisette, the author has followed in minute detail, the essential, while merely paralleling the inessential facts of the real murder of Mary Rogers. Thus all argument founded upon the fiction is applicable to the truth: and the investigation of the truth was the object. The "Mystery of Marie Roget" was composed at a distance from the scene of the atrocity, and with no other means of investigation than the newspapers afforded. Thus much escaped the writer of which he could have availed himself had he been upon the spot, and visited the localities. It may not be improper to record, nevertheless, that the confessions of two persons, (one of them the Madame Deluc of the narrative) made, at different periods, long subsequent to the publication, confirmed, in full, not only the general conclusion, but absolutely all the chief hypothetical details by which that conclusion was attained.

THE BALLOON-HOAX.

[Astounding News by Express, _via_ Norfolk ! - The Atlantic crossed in Three Days ! Signal Triumph of Mr. Monck Mason's Flying Machine ! - Arrival at Sullivan's Island, near Charlestown, S.C., of Mr. Mason, Mr. Robert Holland, Mr. Henson, Mr. Harrison Ainsworth, and four others, in the Steering Balloon, "Victoria," after a pa.s.sage of Seventy-five Hours from Land to Land ! Full Particulars of the Voyage!

The subjoined _jeu d'esprit_ with the preceding heading in magnificent capitals, well interspersed with notes of admiration, was originally published, as matter of fact, in the "New York Sun," a daily newspaper, and therein fully subserved the purpose of creating indigestible aliment for the _quidnuncs_ during the few hours intervening between a couple of the Charleston mails. The rush for the "sole paper which had the news," was something beyond even the prodigious ; and, in fact, if (as some a.s.sert) the "Victoria" _did_ not absolutely accomplish the voyage recorded, it will be difficult to a.s.sign a reason why she _should_ not have accomplished it.]

THE great problem is at length solved ! The air, as well as the earth and the ocean, has been subdued by science, and will become a common and convenient highway for mankind. _The Atlantic has been actually crossed in a Balloon!_ and this too without difficulty - without any great apparent danger - with thorough control of the machine - and in the inconceivably brief period of seventy-five hours from sh.o.r.e to sh.o.r.e ! By the energy of an agent at Charleston, S.C., we are enabled to be the first to furnish the public with a detailed account of this most extraordinary voyage, which was performed between Sat.u.r.day, the 6th instant, at 11, A.M., and 2, P.M., on Tuesday, the 9th instant, by Sir Everard Bringhurst ; Mr. Osborne, a nephew of Lord Bentinck's ; Mr. Monck Mason and Mr. Robert Holland, the well-known aeronauts ; Mr. Harrison Ainsworth, author of "Jack Sheppard," &c. ; and Mr. Henson, the projector of the late unsuccessful flying machine - with two seamen from Woolwich - in all, eight persons. The particulars furnished below may be relied on as authentic and accurate in every respect, as, with a slight exception, they are copied _verbatim_ from the joint diaries of Mr. Monck Mason and Mr. Harrison Ainsworth, to whose politeness our agent is also indebted for much verbal information respecting the balloon itself, its construction, and other matters of interest. The only alteration in the MS. received, has been made for the purpose of throwing the hurried account of our agent, Mr. Forsyth, into a connected and intelligible form.

"THE BALLOON.

"Two very decided failures, of late - those of Mr. Henson and Sir George Cayley - had much weakened the public interest in the subject of aerial navigation. Mr. Henson's scheme (which at first was considered very feasible even by men of science,) was founded upon the principle of an inclined plane, started from an eminence by an extrinsic force, applied and continued by the revolution of impinging vanes, in form and number resembling the vanes of a windmill. But, in all the experiments made with models at the Adelaide Gallery, it was found that the operation of these fans not only did not propel the machine, but actually impeded its flight. The only propelling force it ever exhibited, was the mere _impetus_ acquired from the descent of the inclined plane ; and this _impetus_ carried the machine farther when the vanes were at rest, than when they were in motion - a fact which sufficiently demonstrates their inutility ; and in the absence of the propelling, which was also the _sustaining_ power, the whole fabric would necessarily descend. This consideration led Sir George Cayley to think only of adapting a propeller to some machine having of itself an independent power of support - in a word, to a balloon ; the idea, however, being novel, or original, with Sir George, only so far as regards the mode of its application to practice. He exhibited a model of his invention at the Polytechnic Inst.i.tution. The propelling principle, or power, was here, also, applied to interrupted surfaces, or vanes, put in revolution. These vanes were four in number, but were found entirely ineffectual in moving the balloon, or in aiding its ascending power. The whole project was thus a complete failure.

"It was at this juncture that Mr. Monck Mason (whose voyage from Dover to Weilburg in the balloon, "Na.s.sau," occasioned so much excitement in 1837,) conceived the idea of employing the principle of the Archimedean screw for the purpose of propulsion through the air - rightly attributing the failure of Mr. Henson's scheme, and of Sir George Cayley's, to the interruption of surface in the independent vanes. He made the first public experiment at Willis's Rooms, but afterward removed his model to the Adelaide Gallery.

"Like Sir George Cayley's balloon, his own was an ellipsoid. Its length was thirteen feet six inches - height, six feet eight inches. It contained about three hundred and twenty cubic feet of gas, which, if pure hydrogen, would support twenty-one pounds upon its first inflation, before the gas has time to deteriorate or escape. The weight of the whole machine and apparatus was seventeen pounds - leaving about four pounds to spare. Beneath the centre of the balloon, was a frame of light wood, about nine feet long, and rigged on to the balloon itself with a network in the customary manner. From this framework was suspended a wicker basket or car.

"The screw consists of an axis of hollow bra.s.s tube, eighteen inches in length, through which, upon a semi-spiral inclined at fifteen degrees, pa.s.s a series of steel wire radii, two feet long, and thus projecting a foot on either side. These radii are connected at the outer extremities by two bands of flattened wire - the whole in this manner forming the framework of the screw, which is completed by a covering of oiled silk cut into gores, and tightened so as to present a tolerably uniform surface. At each end of its axis this screw is supported by pillars of hollow bra.s.s tube descending from the hoop. In the lower ends of these tubes are holes in which the pivots of the axis revolve. From the end of the axis which is next the car, proceeds a shaft of steel, connecting the screw with the pinion of a piece of spring machinery fixed in the car. By the operation of this spring, the screw is made to revolve with great rapidity, communicating a progressive motion to the whole. By means of the rudder, the machine was readily turned in any direction. The spring was of great power, compared with its dimensions, being capable of raising forty-five pounds upon a barrel of four inches diameter, after the first turn, and gradually increasing as it was wound up. It weighed, altogether, eight pounds six ounces. The rudder was a light frame of cane covered with silk, shaped somewhat like a battledoor, and was about three feet long, and at the widest, one foot. Its weight was about two ounces. It could be turned _flat_, and directed upwards or downwards, as well as to the right or left ; and thus enabled the aeronaut to transfer the resistance of the air which in an inclined position it must generate in its pa.s.sage, to any side upon which he might desire to act ; thus determining the balloon in the opposite direction.

"This model (which, through want of time, we have necessarily described in an imperfect manner,) was put in action at the Adelaide Gallery, where it accomplished a velocity of five miles per hour; although, strange to say, it excited very little interest in comparison with the previous complex machine of Mr. Henson - so resolute is the world to despise anything which carries with it an air of simplicity. To accomplish the great desideratum of aerial navigation, it was very generally supposed that some exceedingly complicated application must be made of some unusually profound principle in dynamics.

"So well satisfied, however, was Mr. Mason of the ultimate success of his invention, that he determined to construct immediately, if possible, a balloon of sufficient capacity to test the question by a voyage of some extent - the original design being to cross the British Channel, as before, in the Na.s.sau balloon. To carry out his views, he solicited and obtained the patronage of Sir Everard Bringhurst and Mr. Osborne, two gentlemen well known for scientific acquirement, and especially for the interest they have exhibited in the progress of aerostation. The project, at the desire of Mr. Osborne, was kept a profound secret from the public - the only persons entrusted with the design being those actually engaged in the construction of the machine, which was built (under the superintendence of Mr. Mason, Mr. Holland, Sir Everard Bringhurst, and Mr. Osborne,) at the seat of the latter gentleman near Penstruthal, in Wales. Mr. Henson, accompanied by his friend Mr. Ainsworth, was admitted to a private view of the balloon, on Sat.u.r.day last - when the two gentlemen made final arrangements to be included in the adventure. We are not informed for what reason the two seamen were also included in the party - but, in the course of a day or two, we shall put our readers in possession of the minutest particulars respecting this extraordinary voyage.

"The balloon is composed of silk, varnished with the liquid gum caoutchouc. It is of vast dimensions, containing more than 40,000 cubic feet of gas ; but as coal gas was employed in place of the more expensive and inconvenient hydrogen, the supporting power of the machine, when fully inflated, and immediately after inflation, is not more than about 2500 pounds. The coal gas is not only much less costly, but is easily procured and managed.

"For its introduction into common use for purposes of aerostation, we are indebted to Mr. Charles Green. Up to his discovery, the process of inflation was not only exceedingly expensive, but uncertain. Two, and even three days, have frequently been wasted in futile attempts to procure a sufficiency of hydrogen to fill a balloon, from which it had great tendency to escape, owing to its extreme subtlety, and its affinity for the surrounding atmosphere. In a balloon sufficiently perfect to retain its contents of coal-gas unaltered, in quant.i.ty or amount, for six months, an equal quant.i.ty of hydrogen could not be maintained in equal purity for six weeks.

"The supporting power being estimated at 2500 pounds, and the united weights of the party amounting only to about 1200, there was left a surplus of 1300, of which again 1200 was exhausted by ballast, arranged in bags of different sizes, with their respective weights marked upon them - by cordage, barometers, telescopes, barrels containing provision for a fortnight, water-casks, cloaks, carpet-bags, and various other indispensable matters, including a coffee-warmer, contrived for warming coffee by means of slack-lime, so as to dispense altogether with fire, if it should be judged prudent to do so. All these articles, with the exception of the ballast, and a few trifles, were suspended from the hoop overhead. The car is much smaller and lighter, in proportion, than the one appended to the model. It is formed of a light wicker, and is wonderfully strong, for so frail looking a machine. Its rim is about four feet deep. The rudder is also very much larger, in proportion, than that of the model ; and the screw is considerably smaller. The balloon is furnished besides with a grapnel, and a guide-rope ; which latter is of the most indispensable importance. A few words, in explanation, will here be necessary for such of our readers as are not conversant with the details of aerostation.

"As soon as the balloon quits the earth, it is subjected to the influence of many circ.u.mstances tending to create a difference in its weight ; augmenting or diminis.h.i.+ng its ascending power. For example, there may be a deposition of dew upon the silk, to the extent, even, of several hundred pounds ; ballast has then to be thrown out, or the machine may descend. This ballast being discarded, and a clear suns.h.i.+ne evaporating the dew, and at the same time expanding the gas in the silk, the whole will again rapidly ascend. To check this ascent, the only recourse is, (or rather _was_, until Mr. Green's invention of the guide-rope,) the permission of the escape of gas from the valve ; but, in the loss of gas, is a proportionate general loss of ascending power ; so that, in a comparatively brief period, the best-constructed balloon must necessarily exhaust all its resources, and come to the earth. This was the great obstacle to voyages of length.

"The guide-rope remedies the difficulty in the simplest manner conceivable. It is merely a very long rope which is suffered to trail from the car, and the effect of which is to prevent the balloon from changing its level in any material degree. If, for example, there should be a deposition of moisture upon the silk, and the machine begins to descend in consequence, there will be no necessity for discharging ballast to remedy the increase of weight, for it is remedied, or counteracted, in an exactly just proportion, by the deposit on the ground of just so much of the end of the rope as is necessary. If, on the other hand, any circ.u.mstances should cause undue levity, and consequent as
