under the slave system. As has already been set forth in these pages, the greatest cotton crop ever grown before the war with which we here have to deal amounted only to 4,669,770 bales, while under free labor the annual production rose to an average of more than 11,000,000 bales in the closing years of the century which saw the extinction of slavery.
Yet there is no doubt or possibility of doubt that Eli Whitney's invention of the cotton-gin near the end of the eighteenth century made negro slavery profitable as it had never been before in this country. It enabled the planter to grow rich upon the proceeds of the labor of negro slaves whose industry had before produced scarcely more than enough to support themselves. It created a new era. It inaugurated a new epoch. It instigated a new sentiment in favor of slavery, where before the sentiment had been tending the other way.
In considering human affairs historically it is very necessary to bear in mind that men ordinarily have no opinions. If by "opinions" we mean well considered judgments, founded upon an orderly reasoning from accepted premises, then opinions are the very rarest of human possessions. If we are told that a particular person was born and bred in Spain, we know without further inquiry what his religious convictions are. If we learn that he is a Turk we perfectly know his so-called opinions upon the subject of matrimony. We take for granted the views of the Puritans' sons and daughters concerning religion. We know, without asking, what the "opinions" of any American are with respect to the Declaration of Independence. We know that, with the exception of a very few men, all the people of the South were firmly convinced that the cause of the South in the Confederate war was a just one; that the National Government had no conceivable right to coerce recalcitrant states; that secession was an absolute right of the states, and all the rest of it. On the other hand we know that the Northern boy who had declaimed Webster's reply to Hayne was fully imbued with the conviction that "Liberty and Union" were "now and forever, one and inseparable."
In other words, with here and there an exception, men's opinions are determined by geography, tradition, circumstance, self-interest and the like.
Thus when New England's chief interest was maritime and commercial, Daniel Webster was the most radical of free-traders. He held up to ridicule and contumely Henry Clay's protective "American system" and showed conclusively that nothing in the world could be more utterly un-American. But a few years later, when New England's interests were centered in manufactures, Daniel Webster's opinions became those of an extreme protectionist. In the same way he opposed a national bank so long as New England disliked that institution and favored it the moment New England desired its continuance. In like manner John C. Calhoun began by clamoring for the tariff protection of Southern industries and developed into the chief apostle of nullification as a means of escaping protective tariffs. Similarly Clay began by making so absolutely conclusive an argument against a national bank that Andrew Jackson afterwards quoted it as the best possible plea he could offer in support of his warfare upon that institution after Clay had become its chief apostle.
Men ordinarily have no opinions except so far as self-interest, geography, and circumstance determine them and in considering matters of history it is of the utmost importance to recognize that truth.
In the last analysis, therefore, Southern opinion was determined in behalf of slavery by the cotton-gin. And yet the greater number of Southern men were not slaveholders and so had no personal interest in the institution. Their opinions were merely a reflection of the sentiment that surrounded them. That sentiment was born of self-interest on the part of a small but dominant class and it drew to itself the sentiment of that much more numerous class—the white man who owned no negroes. Of the white men in the Confederate army, who made so unmatched a fight for Southern independence, not one in five had ever owned a slave or expected to own one.
And there was another influence at work all this while to create a sentiment at the South in favor of slavery as an institution right in itself, where before it had been almost uniformly regarded as an entail of evil. The circumstances of the national life forced this question into politics and made of it an incalculably exasperating issue.
The Nation having acquired the vast Louisiana territory, invitingly fruitful as it was, the question arose "What shall we do with it?" Men from all quarters of the country wanted to go in and "possess the land." Those of them who came from the South very naturally desired to take their negro servants with them into the new territories, and at first they did so without let or hindrance. Even the Indians of Mississippi, Georgia, Tennessee, South Carolina, and Alabama, when removed, practically by compulsion, to the Indian Territory west of the Mississippi years later were freely permitted to take their negro slaves with them, nobody gainsaying their right. In like manner Southern men emigrating to Missouri took their slaves with them without so much as a question of their right to do so. And when Missouri, in 1819, became sufficiently populous to justify an application for statehood, a majority of the settlers in that region desired that African slavery should be permitted there.
In the meantime, the Northern states, now completely emancipated from slavery within their own borders, had more and more learned to detest the system. There had grown up in the North an intense moral sentiment in antagonism to the further extension of slavery. There had grown up also an intense economic opposition to the system. It was felt that the very existence of slavery in any region tended to degrade free labor and to make of the laborer an inferior person not entitled to respect, a person not quite a slave but still not quite a freeman.
It was, nevertheless, not deemed reputable to advocate the abolition of slavery. The term "Abolitionist" was then, and for a generation afterwards continued to be, the most opprobrious epithet that one man could apply to another.
Nevertheless when Missouri sought admission to the Union as a slave state, the opposition was intense, determined, angry.
Then came Henry Clay with a compromise. Earnestly desiring the extinction of the slave system, it was that statesman's fate to do more than any other man of his era in behalf of the perpetuation and extension of the institution which he regarded as a curse and an incubus. There was one other thing for which he cared far more than he did for the extinction of slavery. In common with Webster and most others of the statesmen of that time he was more deeply concerned for the preservation and perpetuation of the Union than for any other matter that appealed to his mind. His attitude was identical with that of Mr. Lincoln while the war was on, when he declared his sole purpose to be the restoration of the Union and proclaimed his conviction that the question of slavery and all other questions were in his mind subordinate to that.
Clay saw grave danger to the Union in this Missouri controversy. In order to avert that danger, and regardless of everything else, he brought forward his compromise and succeeded in securing its enactment into law.
Under that compromise Missouri was admitted to the Union as a slave state; but it was stipulated that no other slave state should be carved out of territory north of 36° 80´ north latitude, that being the southern boundary line of Missouri.
In practical effect this compromise excluded slavery from all future states to be created out of the vast region embraced in the Louisiana Purchase, except the territory of Arkansas. Louisiana was already a state. Missouri was permitted by the compromise itself to become a state. The Indian Territory was forever set apart for a special purpose and, it was then held, could never become a state. There was no other acre of the Louisiana Purchase lying south of the line fixed by the compromise as the extreme northern limit to which the institution might extend. Texas, New Mexico, Utah, Arizona, California, Nevada, Colorado and the rest were still Mexican possessions which the great Republic had not then the remotest thought of acquiring. On the other hand there were all the vast, fruitful regions now known as Iowa, Kansas, Nebraska, Minnesota, the Dakotas and the states lying to the west of them into which by this agreement slavery might never go, from which it was supposedly as effectually excluded as it had been from Ohio, Indiana, Illinois, Michigan and Wisconsin by that clause which Thomas Jefferson—in his eagerness to make an end of the system—had written into the deed of cession
