On the other hand, it is not impossible that, left to the unimpeded action of the natural laws that govern the existence of various races, the black population, no longer directly preserved and propagated for the purposes of slavery, might gradually decrease and dwindle, as it does at the North—where, besides the unfavourable influence of a cold climate on a race originally African, it suffers from its admixture with the whites, and the amalgamation of the two races, as far as it goes, tends evidently to the destruction of the weaker. The Northern mulattoes are an unhealthy feeble population, and it might yet appear that even under the more favourable influence of a Southern climate, whenever the direct stimulus afforded by slavery to the increase of the negroes was removed, their gradual extinction or absorption by the predominant white race would follow in the course of time.

But the daily course of events appears to be rendering more and more unlikely the immediate effectual enfranchisement of the slaves: the President's proclamation will reach with but little efficacy beyond the mere borders of the Southern States. The war is assuming an aspect of indefinite duration; and it is difficult to conceive what will be the condition of the blacks, freed de jure but by no means de facto, in the vast interior regions of the Southern States, as long as the struggle raging all round their confines does not penetrate within them. Each of the combatants is far too busily absorbed in the furious strife to afford thought, leisure, or means, either effectually to free the slaves or effectually to replace them in bondage; and in the meantime their condition is the worst possible for the future success of either operation. If the North succeeds in subjugating the South, its earliest business will be to make the freedom of the slaves real as well as nominal, and as little injurious to themselves as possible. If, on the other hand, the South makes good its pretensions to a separate national existence, no sooner will the disseverment of the Union be an established fact than the slaveholders will have to consolidate once more the system of their 'peculiar institution,' to reconstruct the prison which has half crumbled to the ground, and rivet afresh the chains which have been all but struck off. This will be difficult: the determination of the North to restrict the area of slavery by forbidding its ingress into future territories and States has been considered by the slaveholders a wrong, and a danger justifying a bloody civil war; inasmuch as, if under those circumstances they did not abolish slavery themselves in a given number of years, it would infallibly abolish them by the increase of the negro population, hemmed with them into a restricted space by this cordon sanitaire drawn round them. But, bad as this prospect has seemed to slaveholders (determined to continue such), and justifying—as it may be conceded that it does from their point of view—not a ferocious civil war, but a peaceable separation from States whose interests were declared absolutely irreconcileable with theirs, the position in which they will find themselves if the contest terminates in favour of Secession will be undoubtedly more difficult and terrible than the one the mere anticipation of which has driven them to the dire resort of civil war. All round the Southern coast, and all along the course of the great Mississippi, and all across the northern frontier of the Slave States, the negroes have already thrown off the trammels of slavery. Whatever their condition may be—and doubtless in many respects it is miserable enough—they are to all intents and purposes free. Vast numbers of them have joined the Northern invading armies, and considerable bodies of them have become organised as soldiers and labourers, under the supervision of Northern officers and employers; most of them have learned the use of arms, and possess them; all of them have exchanged the insufficient slave diet of grits and rice for the abundant supplies of animal food, which the poorest labourer in that favoured land of cheap provisions and high wages indulges in to an extent unknown in any other country. None of these slaves of yesterday will be the same slaves to-morrow. Little essential difference as may yet have been effected by the President's proclamation in the interior of the South in the condition of the blacks, it is undoubtedly known to them, and they are waiting in ominous suspense its accomplishment or defeat by the fortune of the war; they are watching the issue of the contest of which they well know themselves to be the theme, and at its conclusion, end how it will, they must be emancipated or exterminated. With the North not only not friendly to slavery, but henceforward bitterly hostile to slaveholders, and no more to be reckoned upon as heretofore, it might have been infallibly by the Southern white population in any difficulty with the blacks (a fact of which the negroes will be as well aware as their former masters)—with an invisible boundary stretching from ocean to ocean, over which they may fly without fear of a master's claim following them a single inch—with the hope and expectation of liberty suddenly snatched from them at the moment it seemed within their grasp—with the door of their dungeon once more barred between them and the light into which they were in the act of emerging—is it to be conceived, that these four millions of people, many thousands of whom are already free and armed, will submit without a struggle to be again thrust down into the hell of slavery? Hitherto there has been no insurrection among the negroes, and observers friendly and inimical to them have alike drawn from that fact conclusions unfavourable to their appreciation of the freedom apparently within their grasp; but they are waiting to see what the North will really achieve for them. The liberty offered them is hitherto anomalous, and uncertain enough in its conditions; they probably trust it as little as they know it: but slavery they do know—and when once they find themselves again delivered over to that experience, there will not be ONE insurrection in the South; there will be an insurrection in every State, in every county, on every plantation—a struggle as fierce as it will be futile—a hopeless effort of hopeless men, which will baptise in blood the new American nation, and inaugurate its birth among the civilised societies of the earth, not by the manumission but the massacre of every slave within its borders.

Perhaps, however, Mr. Jefferson Davis means to free the negroes. Whenever that consummation is attained, the root of bitterness will have perished from the land; and when a few years shall have passed blunting the hatred which has been excited by this fratricidal strife, the Americans of both the Northern and Southern States will perceive that the selfish policy of other nations would not have so rejoiced over their division, had it not seemed, to those who loved them not, the proof of past failure and the prophecy of future weakness.

Admonished by its terrible experiences, I believe the nation will reunite itself under one government, remodel its constitution, and again address itself to fulfill its glorious destiny. I believe that the country sprung from ours—of all our just subjects of national pride the greatest—will resume its career of prosperity and power, and become the noblest as well as the mightiest that has existed among the nations of the earth.
