Seldom have we read a nobler passage than that in which this accomplished writer appeals to the French sentiment of national unity to justify our Northern people in their mighty struggle to subdue this 'impious revolt.' Americans themselves, though fully imbued with the instinctive feeling which it defends, could not more forcibly have presented the point. And, indeed, if we may believe the statements now prevalent, attributing to eminent statesmen and large parties a disposition to accede to the separation of the sections, the very sentiment of nationality has lost it force among us, and we would be compelled to acknowledge our obligations to this eminent Frenchman for stimulating our expiring patriotism and awakening us to the vital importance of our national unity and to the shame and disgrace of surrendering it. If any American has ever, for a moment, admitted the idea of consenting to a separation of the Union, let him read the burning words of this enlightened and disinterested foreigner, and blush for his want of comprehension of the true interests and glory of his country. It is not a mere sentimental enthusiasm which leads us to combat disunion and to cherish the greatness and oneness of our country. Our dearest rights and our noblest interests are alike involved, and we would be craven wretches, unworthy of our high destiny, if we did not risk everything and sacrifice everything to preserve them. 'The North only defends itself,' says M. Laboulaye. 'It is its very life that it wishes to save.'

Briefly, but with the hand of a master, does this article point out the consequences of disunion. The touches by which the sketch is drawn, are few and rapidly made; but they faithfully portray the great features of the case, and present a true and living picture to the mind of every thoughtful man. The jealousies, the rivalries, the antipathies of the sections; the foreign intrigues and eventual foreign domination among our fragmentary governments; the large standing armies, and the competing naval forces; and finally, 'the endless war and numberless miseries' which will inevitably result—all these mighty evils will not only afflict our own unhappy country, but 'peace will be exiled from the world.' The interests of mankind are involved in this tremendous struggle.

But we no longer keep our readers from the perusal of this interesting extract. Let it be remembered that it comes from the quarter understood to be most unfriendly to us, where the wily emperor of the French is supposed to be plotting for the destruction of our nationality and power. The appeal to the interests of France against the ambition of England is striking and powerful. Whatever disposition the emperor may cherish against us, the French people ought to be our friends; they have a common interest in maintaining the freedom of the seas, and we have yet to complain that any port of France has sent out cruisers to assail our commerce on the ocean.

Let us take courage, even in this hour of disaster. Noble spirits abroad are still watching us with generous sympathy and praying for the success of our sacred cause. Let us be true to ourselves and to our country, and the hour of final triumph will soon be at hand. Though dissensions tend now to distract and weaken us, and though darkness, more impenetrable than ever before, seems lately to have gathered around us, we already discern the first glimmerings of the dawn in the east. The full day will soon break upon us, and we shall rejoice in the splendor of returning peace and renewed prosperity.

REASONS WHY THE NORTH CANNOT PERMIT SECESSION.

(From the French of Edouard Laboulaye, published in the 'Revue Nationale,' December 10th, 1862.)

The civil war which has been dividing and ruining the United States for two years also affects us in Europe. The scarcity of cotton causes great suffering. The workmen of Rouen and Mulhouse are as severely tried as the spinners and weavers of Lancashire; entire populations are reduced to beggary, and to exist through the winter they have no resource and no hope save in special charity or assistance from the government. In so severe a crisis, and in the midst of such unmerited sufferings, it is but natural that public opinion should become restless in Europe, and condemn the ambition of those who prolong a fratricidal war. Peace in America, peace is a necessity at any price, is the cry of thousands of men among us who are suffering from hunger, innocent victims of the passions and madness which steep the United States in blood.

These complaints are only too just. The civilized world is at present, so bound together, that peace is one great condition of the existence of modern industrial nations; unhappily, although it is easy to point out the remedy, it is almost impossible to apply it. Just now it is by war alone that ending of the war may be looked for. To throw herself armed between the combatants would be an attempt in which Europe would exhaust her strength; and to what purpose? As Mr. Cobden has justly said, it would be less costly to feed the work people who are ruined by the American crisis on game and champagne. To offer to-day our friendly mediation is not only to expose ourselves to a refusal, and perhaps so exasperate one of the parties as to push it to more violent measures, but to diminish the chances of our mediation being accepted at a more favorable moment. Thus we are forced to remain spectators of a deplorable war, which is the cause of infinite evil to us; thus forced to offer up prayers that exhaustion and misery may appease these mortal enemies and oblige them to accept either reunion or separation. A sad situation, doubtless, but one which neutrals have always occupied, and from which they cannot depart without throwing themselves among unknown dangers.

If we have not the right to interfere, we can at least complain, and try to discover those who are really wrong in this war, which so affects us. The opinion of Europe is a power. It can hasten matters and restore peace better than arms can. Unfortunately, for two years opinion has wandered from the proper path, and by taking the wrong side of the question, prolongs instead of stopping resistance. The South has found many and clever advocates in England and in France, who have presented her cause as that of justice and liberty. They have proclaimed the right of secession, and have not feared to apologize for slavery. Their arguments to-day are beginning to fail. Thanks to those publicists who do not traffic with humanity; thanks to M. de Gasparin, above all, the light has made things clear; we know now how things stand as to the origin and character of the rebellion. To every disinterested observer, it is evident that the South is wrong in every way. It needs not a Montesquieu to understand that a party not menaced in the least, which, through ambition or pride, tears its country to pieces and destroys its national unity, has no right to the sympathies of the French. As to declaring slavery sacred, that is a work which must be left to the preachers of the South. All the ingenuity in the world cannot lift up this fallen cause. Had the confederates a thousand reasons for complaint and for revolt, there would always rest on their rebellion an indelible stain. No Christian, no liberal person will ever interest himself for men who, in this nineteenth century, insolently proclaim their desire to perpetuate and extend slavery. Though it is still permitted to the planters to listen to theories that have infatuated and lost them, such sophistries will never cross the ocean.

The advocates of the South have done it a fatal service; they have made it believe that Europe, enlightened or seduced, would range itself on its side and finally throw into the balance something more than empty promises. This delusion has and still maintains the resistance of the South, it prolongs the war, and with it our sufferings. If, as the North had a right to expect, the friends of liberty had, from the first, boldly pronounced against the policy of slavery, if the advocates of peace upon the seas, if the defenders of the rights of neutrals had spoken in favor of the Union and rejected a separation, which could only profit England, it is probable that the South would have been less anxious to start on a journey without visible end. If, in spite of the courage and devotion of its soldiers; if, in spite of the ability of its generals, the South fails in an enterprise which, in my opinion, cannot be too much blamed, let it lay the fault on those who have so poor an opinion of Europe as to imagine that they will subject its opinion to a policy against which patriotism protests, and which the gospel and humanity condemn.
