It is seen by this table that the income, or product of the non-slaveholding population South, mainly disconnected as it is with mechanical industry, is reduced to the extreme level of bare subsistence, while the population of the States which have introduced diversified industry stand on a high scale of production. Contrast Massachusetts and South-Carolina, the two leading States in the promulgation of opposite theories. These two States have often been censured for the contumelious manner in which they have sometimes sought to repel each other's arguments. The one is in favor of 'free trade.' The other says: 'No State can flourish to much extent without diversified industry.' The one says: 'Open every thing to free competition.' The other replies: 'Are you aware that the interest on manufacturing capital in Europe is much lower; that skilled labor there is more abundant; and that it would dash to the ground most of the manufacturing we have started into growth under protection through our revenue laws?' 'Let it be so,' says Carolina; 'what right exists to adopt a national policy that does not equally benefit all sections?' 'The very object of the policy,' replies Massachusetts, 'is, that it should benefit all sections; and the most desirable object of all, in the eye of beneficence, would be, that it should benefit the laboring white population of the cotton States, as well as others.' 'But,' says Carolina, 'this diversified industry can not be introduced, to much extent, where slavery exists.' 'That is an argument by implication,' says Massachusetts, 'that you more prize slavery than you do the interests and welfare of the bulk of your white population.' 'Who set you up to be a judge on the question of the welfare of any part of the population South?' says Carolina. 'I assume to judge for myself,' replies Massachusetts, 'as to that national policy which is designed to affect beneficially the twenty-seven millions of people who are obliged to obtain subsistence through personal industry; theirs is the great cause of white humanity in its shirt-sleeves; and it behooves the National Government to take care of that cause, and to foster it; and not to submit to the narrow selfishness of a few slaveholders.'

It may readily be seen that this controversy, growing out of the opposite theories of selfish slaveholders on the one hand, and a spirit of beneficence, blended with the idea of a wide-spread advantage on the other, not only involves directly the demerits of slavery, in its prejudicial effect on the non-slaveholding population South, but also the great question of raising up skilled labor in all the States. It is thus clearly demonstrated that our national policy should be exempt from the control of an arrogant and selfish class. Slaveholders have had little sympathy with the great bulk of the white people in the Union; at most, they have never manifested it. Few of them can be trusted politically, where a broad industrial policy is concerned. No one is better aware than the political slaveholder of the crushing effect of slavery on the interests of the non-slaveholding population in the slave States: hence their jealousy of this population as a voting, governing power. The Southern political mind, connected with slaveholding, is astute when sharpened by jealousy. There is no phase in political economy, bearing on the disparity of classes in the South, that has not been taken into the account and analyzed. The fear with slaveholders has been, that the great majority, composed of the white laboring population South, would become able to subject matters to the same scrutinizing analysis.

It would be difficult to convince the American people that slavery is not 'the skeleton in their closet.' Any one who has encountered for years the pro-slavery spirit; who has watched it through its unscrupulous deviations from rectitude, morally, socially, and politically, will have been dull of comprehension not to have appreciated its atrocious disposition. Its great instrumentality in the management of Southern masses, consists not only of a disregard, but of a positive interdict of the principles of civil liberty, in all matters wherein the prejudicial effects of slavery might directly, or by implication, be disclosed. It is true, people are permitted to adulate slavery—so they are allowed to adulate kings, where kings reign. No one in recent years has been allowed the open expression of opinion or argument as to the bad effect of a pro-slavery policy on the great majority of Southern white population. This would bring the offender within the Southern definition of an 'incendiary,' and the offense would be heinous. The pro-slavery spirit has always demanded sycophancy where its strength was great enough to enforce it, and has ever been ready to invoke the law of force where its theories were contradicted. Even the fundamental law of the South, contained in Southern State Constitutions in favor of the 'freedom of speech, and freedom of the press,' is mere rhetorical flourish, where slavery is concerned. It means that you must adulate slavery if you speak of it; and woe to the man that gives this fundamental law any broader interpretation. In its amiable moods, the pro-slavery spirit is often made to appear the gentleman. In its angry, jealous moods, it is both a ruffian and an assassin. Mr. Sumner, of the Senate, once sat for its picture—twice in his turn he drew it—each portrait was a faithful resemblance.

Had we been exempt from slavery and its influences, it is difficult to conceive what possible pretense could have been raised up for revolution. What position could have been taken showing the necessity of disenthrallment from oppressive government? There would have existed no element of political discontent that could by any possibility have culminated in rebellion, aside from the active, jealous, and unscrupulous influence of slaveholders. Rebellion and treason required the lead and direction of an ambitious and reckless class; a class actuated by gross and selfish passions, in disconnection with sympathy for the masses. It required a class stripped and bereft by habits of thinking of the spirit of political beneficence, devoid of national honor, national pride, and national fidelity. Nothing less unscrupulous would have answered to plot, to carry forward, and to manage the incidents of the attempted dismemberment of the Union. It required something worse in its nature than Benedict Arnold susceptibility. His might have been crime, springing from sudden resentment or imaginary wrong. The other is the result of thirty years' concoction under adroit, hypocritical, and unscrupulous leaders. The slaveholders' rebellion has assumed a magnitude commensurate only with long contemplation of the subject. Making all due allowance for the honorable exceptions, this is substantially the phase of pro-slavery infidelity to the Union.

Were further argument needed to establish this position, it is found in the fact that the seeds of rebellion are wanting in proportion to the absence of slavery. There is no reason to believe that Kentucky or Maryland, without slavery, would have been less loyal than Ohio. In Eastern Kentucky, Western Virginia, Eastern Tennessee, Western North-Carolina, a small portion of Georgia, and Northern Alabama, the Union cause finds a friend's country. These sections, in the main, contain a population dependent upon its own labor for subsistence. Schooled by diligent industry to habits of perseverance, and learning independence and manhood by relying on itself, it has preserved its patriotism and attachment to the Government under which it was born. It saw no cause of complaint, imaginary or real. Six or seven per cent of slave population has not proved sufficient as a slave interest, to prostrate or corrupt its national fidelity, nor to undermine its national pride. It still retains its representation in Congress against the influences of surrounding treason. There is a cheering satisfaction in the belief that this plateau of civil liberty and freedom, even unassisted, could not have been permanently held in subjection by the myrmidons of rebellion. The secessionists themselves bestow a high compliment to the patriotism of this people, when they complain of its 'idolatrous attachment to the old Government.'

The time has come when the American people, from necessity, must analyze to their root the whole aptitudes and incidents of slavery. They are now obliged to deal with it, unbridled by the check-rein of its apologists. Under the best behavior of slaveholders, the institution could not rise above the point of bare toleration. There is so much inherent in the system that will not bear analysis, so much of collateral mischief, so much tending to overturn and discourage the principles of justice that ought to be interwoven into the relationships of society, that it is impossible for the ingenuous mind to advocate slavery per se. It is not, however, to the bare dominion itself, that the objection is exclusively raised up. It is the inevitable result of that dominion, in connection with the worst cultivated passions of human nature, that the exception is more broadly taken. The dominion of the master over the slave involves in a great measure the necessary dominion over the persons and interests of the balance of society where it exists. The lust of power on the part of slaveholders, and on the part of the privileged classes in Europe, in nature, is the same. The determination through the artificial arrangements of power, to subsist on the toil of others, is the same. The arrogant assumption of the right to maintain as privilege what originated in atrocious wrong, is the same. The disposition to crush by force any attempt to vindicate natural rights, or to modify the status of society under the severity of oppression, is the same; and no tyranny has yet been found so tenacious or objectionable as the tyranny of a class held together by the 'bond of iniquity.' Our forefathers had a just conception of the nature of the case, on one hand, when they interdicted by fundamental law the establishment of any order of nobility. Many of them were sorely distressed at the contemplation of slavery on the other hand, in connection with its probable results upon the national welfare. Our calamity is but the fulfillment of their prophecies. They well knew the nature of the evil we have to deal with.

It is matter of astonishment to most minds that slaveholders should have contemplated the bold venture of subordinating the Democratic principle in government. It will be less astonishing, however, when it is duly considered that it is utterly impossible for Democracy and Slavery to abide long together. The one or the other must ere long have been prostrated under the laws of population, and it is not very likely that the twenty-seven millions and their increase would consent to be subordinated to the policy of three hundred and fifty thousand slaveholders. Slavery must exist as the ruling political power, or it can not long exist at all. This the slaveholders well knew; hence the necessity of fortifying itself through some political arrangement against the Democratic power of the masses.

The South-Carolina platform for a new government had close resemblance to the ancient Roman—a patrician order of nobility, founded on the interested motive to uphold slavery; but allowing plebeian representation, to some extent, to the non-slaveholding classes. Others in the South had preference for constitutional monarchy, with a class of privileged legislators, and House of Commons, composing a government of checks and balances, analogous to the English government. Whatever the plan adopted, the leading idea was to institute a government that should be impervious, through one branch, to the future influence of the non-slaveholding majority.

It is difficult to make entirely clear the ambitious motives and mixed apprehensions that have combined to precipitate the Southern slaveholders into rebellion. The defectiveness of the educational system of the South, and the known responsibility of slaveholders for such defect and its consequences; the defect in the industrial policy, and the responsibility of slavery itself for the depressing consequences to the non-slaveholding population, were fearful charges. A knowledge that the causes of depression must soon be brought to the examination of Southern masses, in contrast with a better state of things in the North, filled the minds of slaveholders with jealous and fearful apprehensions toward the non-slaveholding population. They knew that its interests were identified with the Northern educational and industrial policy. They appreciated fully that through these interests, free labor in the South had every motive to affinity with the North, educationally, politically, and industrially. They were astute in the discovery that under the operation of the Democratic principle, free discussion, and fair play of reason, the pro-slavery prestige must soon go down in the South before the greater numerical force of Southern masses. It was, therefore, not only necessary, as supposed, to overturn the power of the masses in the South, but also to make them the instruments of their own overthrow as to political power.

The measurable acquiescence of the non-slaveholding population was indispensable to the revolutionary project. Without it, there was but little numerical force. It was, therefore, of entire consequence to make this population hate the North—to hate the National Government, and to train it for the purposes of rebellion. The press was suborned wherever it could be. The pulpit manifested equal alacrity, in order to keep pace with the workings of the virus of treason. Leading men, assuming to be statesmen and political economists, taxed their ingenuity in the invention of falsehood. The effort of the press and politicians was directed to misrepresenting and disparaging the condition of free labor in the North; whilst the Southern pulpit was religiously engaged in establishing the divinity of slavery. It would require a volume to delineate the arts and hypocrisy resorted to, and the false reasoning employed, to impose upon the masses of white labor South, and to make them contented with their disparaged condition. It is needless to say, the work of imposition was too effectually accomplished. It must be confessed that too much of the non-slaveholding population had been induced to follow the political Iagos of the South, and thus to assist the first act in the plan for its own subversion—separation from the North. The next step in the plan of subversion, the 'abrogation of a government of majorities,' was carefully kept from the public view.
