The confident belief, that an unusual strain on the supposed weak points of the Federal Constitution would involve it in the fate of the Cromwell dynasty and the French Revolution had begun to sleep, at the time of the Secession movement, and but one ray of hope yet remained to the enemies of republican government. They watched Slavery with an anxious eye. There was their only chance. In that they saw the apple of discord which might destroy our Union. They observed with exultation the increasing influence of those who warred upon slavery in the North, and the increasing insolence of those who would nationalize it in the South. On this ground State and Federal authority must, they thought, come in conflict. And as far as foresight could avail them, they had some reason to be encouraged. That question has always been, without doubt, our greatest, almost our only danger.

There is reason to believe, then, that, when the Rebellion broke out, the theorists of Europe deemed the test to have come, and that the final success or failure of the Federal Constitution was staked on the result. The people of the United States have been willing to accept that issue. We have been ready to test the doctrines of Democracy by the practicability of maintaining the Union, and to demonstrate, that, if need be, the General Government may receive at the hands of the people greater strength without endangering either their liberties or the order of law.

The diplomatic correspondence between the State Department and our ministers to foreign powers during the present contest is contained in two large volumes, published by the Government, which are full of valuable matter. In the limited space permitted us, but little more than a general survey of this correspondence can be attempted; and as our relations with England far exceed all others in closeness and interest,—a striking proof of which is found in the fact that the room occupied in these volumes by communications with that country is greater than that given to all the world besides,—we mainly confine ourselves to the portion which regards her.

England stands in the somewhat anomalous attitude of being to us the champion of the old monarchical principle, and to Europe the champion of Anglo-Saxon progress; so that the dicta of her thinkers (those who have opposed our Republic) may be regarded as the best thought of the most enlightened monarchists in the world. As the ministry are obliged, however unwillingly, to represent as well the popular as the aristocratic ideas, through them there comes to us a pretty correct exposition of the different opinions entertained by all classes. We may regard two facts as well established, one leading out of the other,—that England has ever been, and is, the most selfish of nationalities, and that she does not desire the prosperity of any power which may become a rival. With her politicians and her philosophers, Tory and Whig, Churchmen and Dissenters, the ascendancy of Great Britain has lain at the bottom of every policy, and has been the postulate of every theory. Her history is that of a nationality eager to attain the distinction of the first of powers. This fact, and this alone, can reconcile the apparent inconsistencies of her record. At one time the bold accuser of Despotism, she has with marvellous celerity turned to the inthralment of oppressed races. Maxim has superseded maxim, until her code of international law is a bewildering complication of anomaly and contradiction. To humble her rivals by every means, and to encourage the efforts of a people striving for freedom only when decided advantage would accrue to herself, has been her constant policy. This is true of the general tone of her successive cabinets, of the press, and of those politicians who have by comfortable doctrines most successfully gained the public ear.

The classes who look at questions of policy with an eye to expediency are, the leading statesmen of both parties, who regard as the proper end of their labors the interests of Great Britain, and the business-community, who judge of every political event by the manner in which it affects their pockets. There are two other classes, who take a higher view,—those who are conservative and fearful of innovation, and those who believe in the progressive tendency of the Anglo-Saxon. Within the last quarter of a century, the public opinion of England has been undergoing a great change, especially that part of it which is influenced by the lower-middle class. The people have been growing up to the adoption of liberal principles of government. The Reform Bill of 1832 was a great stride in that direction; and the measures which have followed upon it have widened the observation of the masses, made the sense of political wrong quicker, and the appreciation of a free system much more vivid. As a natural result, the attention of this class has been drawn toward America, as the exponent of a government before which all men are equal,—and so it is, that, as the Rebellion goes on, we receive weekly evidence that the sober, honest thought of English opinion is with us of the North. The class to which we refer, if it is not now, will very shortly be, the governing element. The tendency is irresistibly that way; the signs of its growing power are daily more and more manifest. That it should be deeply interested in the perpetuity of American institutions, as affecting its own position, is natural. In the failure of man's self-governing capacity here, where every circumstance has been favorable to its exercise, the rising spirit of a broader liberty in England must foresee the death-blow to its own hopes. Our failure will not be fatal to us alone; it will involve the fate of the millions who are now seeking to plant themselves against the tremendous force of kingly and patrician prestige. They have hitherto derived from our example all the inspiration with which they have struggled upward. They have been able to accomplish, step by step, important alterations in the unwritten constitution, by the apt comparisons their leaders have been able to make between American and British civilization. So that, in considering the forces at work to influence those at the head of affairs, it is necessary to consider that force which is imperceptibly, but subtly, brought to bear upon them by the working-class. Mr. Beecher, and other eminent Americans who have lately visited England, tell us that this class are almost to a man sympathizers with us; and that this sympathy has in many cases worked favorably to us cannot be doubted. Even the operatives and manufacturers of Manchester and Leeds, at first, a little morose because of the effect of the war on their industry, seem to have come to a better second-thought, and are now outspoken for the North.

The different elements of English feeling toward us may be, we think, stated thus. The aristocracy would view with complacency the disruption of the Union, because we are a rival power, and they are thoroughly pledged to British aggrandizement; because the success of the Union would belie the principle whence they derive their prerogative, and encourage the opposing element of popular rights to greater exertions for ascendancy; because hatred of democracy is a sentiment inherited, as well as a principle of self-preservation; and because they have not forgotten the former dependence of America on England. The ministry feel toward us as the servants of a jealous power would naturally feel toward a rival. The theorists are eager for events to crown them with the flattery of verified prediction. The commercial classes are ill pleased that their thrift should be curtailed; the manufacturers grumble about the scarcity of cotton. The timid minds of some honest thinkers did not see the real issue, until the regular developments of the war satisfied them; the lower orders had to be told before they could comprehend that in our destiny they must read the counterpart of their own. Those pretentious philanthropists who have assumed to direct the anti-slavery party in England have mostly espoused the Southern side of the quarrel; thus demonstrating that their moral scruples have no higher source than their own political advantage, and no more lofty end than to divide and distract a sister-nation. Of these we may instance the most conspicuous of all, Lord Brougham,—who, after having for half a century derived all the benefit he could from the striking and pathetic points in slavery to vivify his eloquence, turns the bitter vial of his dotage against those who stake everything upon its extinction. But everybody knows that Lord Brougham is a type of those statesmen who stand by the people in the Commons and grind the people in the Lords; who, after crying down public wrongs, upon finding the responsibility of a coronet on their shoulders, suddenly become arrant sticklers for hereditary rights. We are amused to notice, among those peers who have risen above the selfishness by which they are surrounded, and have given us a well-timed sympathy, but few who are of new creations: for the Duke of Argyle and the Earls of Carlisle and Clarendon are descendants of the oldest and proudest houses in the realm.

It is gratifying to observe that those forces which are operating against us are those which are rapidly losing that control in public affairs which belonged to past phases of society; while those forces which are proper to the present, and are inevitably to assume the preponderance in the future, appear as they develop to be more and more sympathetic with the cause of our national integrity. Aristocratic prestige is shrinking back before an advancing enlightenment which elevates all to equal dignity.

The present ministry is a fair type of the selfishness of British statesmanship. The antecedents of its principal members are those of timeserving politicians. Lord Palmerston, starting on his career as a Tory of the Wellington stamp, has veered round as the tide has turned against his former associates, and is the still distrusted representative of the Liberal party. Lord Russell, in the youth of his public service a Radical reformer, and the eager disciple of Sir Francis Burdett when Sir Francis Burdett could not lead a corporal's guard, once the prop and hope of those who sought a wider suffrage, has again and again eaten his own words, and the history of his political life is a ludicrous illustration of the perplexities of politicians. His invariable course as a diplomatist has been to leave the way open to prevarication, to keep his opinions in a cloud, and to confound sense with ambiguity. It would be pure credulity to place much confidence in the expressions of a statesman who within two months boldly censured and then as boldly favored the designs of Victor Emmanuel on Venice, officially and unblushingly before all Europe. Both these noble lords, however, are fortunate in a keen appreciation of the national prejudices, and know how to make use of the existing tone of public feeling. A long vicissitude of successes and failures has taught both a lesson which is every day a practical benefit; and after finding that they were powerless when mutually opposed, they have succeeded in swallowing the hatred of half a century, that they may join and divide the power. The fact that there has been for some time a Tory majority in the House of Commons shows the cunning with which Palmerston manœuvres his machinery. If we could conclude at all from his acts what his sentiments are toward America, there is little love wasted on us from that quarter; and Lord Russell, even while addressing the House of Lords in terms favorable to us, never lets the occasion pass without slipping in a sneer between his praises.

Selfishness, national or individual, is ever cautious and ever suspicious. It seldom rashly grasps the thing coveted: it oftener lets the apt occasion pass without improvement. The diplomatic intercourse between Lord Palmerston's government and our own for the last year or two amply illustrates this. He had in the first place no prepossession in favor of the United States. We believe that he was not at all unwilling to see the Union dissolved. It was natural for a statesman hardened by fifty years of intrigue and devotion to politics to look with absolute gratification upon what seemed the dissolution of a great, and, because a near, a hated rival. We do not think it too much to assume, that, as far as Palmerston's personal feelings were concerned, he was ready for the chance of Southern recognition at the outset. In such a sentiment, he had the sympathy of the aristocracy, and of all others who take the low standard of self-aggrandizement in determining opinions. Two circumstances, however, were a restraint upon him, and appealed with controlling force to his caution. He was not only an aristocrat and a hater of republics, he was also the Prime-Minister of all England. He was absolutely dependent to a great degree upon the lower orders for the permanence of his present dignity. Was it wise in him to disregard the sentiments of those who were advancing to the predominance, and resort for support to those whose power was rapidly waning, whose opinions were yielding to the newer intelligence? Would it not be fatally inconsistent in a Liberal statesman to override every Liberal maxim and belie every Liberal profession? Was not the popular current too strong to be safely defied? There were Liberal statesmen enough of conspicuous merit to take his place at the helm, should he make the misstep: Gladstone, Gibson, Herbert, Granville, would fully answer the popular demand: his downfall, if it came, would doubtless be final. His private feelings, therefore, even his political wishes, must yield to policy. His love of place is too strong to succumb either to personal prejudice or national jealousy; and the long habit has made the self-denial more easy.

The other reason why Lord Palmerston has withheld open comfort from the Rebels is doubtless to be found in the steady adherence of our Government to the position which it assumed at the beginning,—in the promptness with which we have insisted upon our rights throughout the world,—the grace with which we have disavowed the evident errors of public servants,—the steadiness of our military progress,—the ease with which we have borne the strain upon our resources in respect both of men and money,—the possible, if not probable, success of the war,—the certainty that that success would strengthen our system, and render us capable of resenting foreign insult. For while Lord Palmerston and Lord Russell are very apt to stalk about and threaten and talk very loudly at nations whose weakness causes them not to be feared, and by bullying whom some power or money may slide into British hands, they are slow to provoke nations whose resentment either is or may become formidable to British weal. The British lion roars over the impotence of Brazil: he lies still and watches before the might of Napoleon. In the one case he stands forth the lordly king of beasts; in the other he seems metamorphosed into the fox. The hope that America would descend incontinently to the rank of an inferior power was quickly dispelled; so the lion crouched and the foxy head appeared. The everlasting caution came in and said,—"Wait your chance; a hasty judgment is always a poor judgment; let events take their course, and if occasion offers, strike the right blow at the right time; but do not decree away the stability of the Union either by the illusion of hope or by an expectation as yet ill-founded." It was the wisdom of the serpent, eager, and conquering eagerness.
