There is still another point requiring a passing notice, as it may serve to explain some portions of the history of slavery, not so well understood. It was not until events diminishing the foreign growth of cotton, and enlarging the demand for its fabrics, had been extensively developed, that the older cotton-growing States became willing to allow slavery extension in the Southwest; and, even then, their assent was reluctantly given--the markets for cotton, doubtless, being considered sufficiently limited for the territory under cultivation. Up to 1824, the Indians held over thirty-two millions of acres of land in Georgia, Mississippi, and Alabama, and over twenty millions of acres in Florida, Missouri and Arkansas; which was mostly retained by them as late as 1836. Although the States interested had repeatedly urged the matter upon Congress, and some of them even resorted to forcible means to gain possession of these Indian lands, the Government did not fulfill its promise to remove the Indians until 1836; and even then, the measure met with such opposition, that it was saved but by one vote--Mr. Calhoun and six other Southern Senators voting against it.[32] In justice to Mr. Calhoun, however, it must be stated that his opposition to the measure was based on the conviction that the treaty had been fraudulently obtained.
The older States, however, had found, by this time, that the foreign and home demand for cotton was so rapidly increasing that there was little danger of over-production; and that they had, in fact, secured to themselves the monopoly of the foreign markets. Beside this, the abolition movement at that moment, had assumed its most threatening aspect, and was demanding the destruction of slavery or the dissolution of the Union. Here was a double motive operating to produce harmony in the ranks of Southern politicians, and to awaken the fears of many, North and South, for the safety of the Government. Here, also, was the origin of the determination, in the South, to extend slavery, by the annexation of territory, so as to gain the political preponderance in the National Councils, and to protect its interests against the interference of the North.
It was not the increased demand for cotton, alone, that served as a protection to the older States. The extension of its cultivation, in the degree demanded by the wants of commerce, could only be effected by a corresponding increased supply of provisions. Without this, it could not increase, except by enhancing their price to the injury of the older States. This food did not fail to be in readiness, so soon as it was needed. Indeed, much of it had long been awaiting an outlet to a profitable market. Its surplus, too, had been somewhat increased by the Temperance movement in the North, which had materially checked the distillation of grain.
