Next to maintaining our finances and the public credit, followed by decisive victories in the field, the speedy success of emancipation in Missouri is most important. Missouri is larger by more than 6,000 square miles than any State east of the Mississippi, and occupies a central position between the North and the South, the East and the West. She is larger by 16,458 square miles than England proper, containing a population of nineteen millions. She is larger by 1,098 square miles than New York, Vermont, Massachusetts, Rhode Island, and Delaware. She is larger by 5,264 square miles than all the New England States. She has a greater white population than the aggregate numbers of North and South Carolina and Florida, or of South Carolina, Georgia and Florida, or of Arkansas, Louisiana and Mississippi, or of Florida, Arkansas, South Carolina and Mississippi, or Louisiana; and a larger white population than all Virginia, East and West. She had, if disloyal, by her position and large white population, more power to imperil the Union than any of the slaveholding States. She has been true--she has suffered much in our cause, her fields and towns have been laid waste, thousands of her brave sons now fill our armies, and thousands more have fallen in our cause, and we will be recreant to truth and justice, to the safety of the Union, and forfeit the nation's pledge, if we do not now aid her in becoming a Free State. The southern boundary of Missouri (lat. 36°) is several miles south of Nashville, Tennessee; but, if we take altitude also into consideration, then, according to well established meteorological principles, the southern boundary of Missouri is at least a degree south of Nashville, reaching the northern boundary of Alabama. There is then a very large area of Missouri well calculated for the production of cotton. To accomplish this, the levee system of the Mississippi must be extended from the southern boundary of Missouri to the first highlands in that State, above the mouth of the Ohio; and a proper system of drainage adopted. These lands would thus be entirely secured from overflow, and greatly improved in salubrity. With these improvements, Missouri would contain an area of rich alluvial lands, well adapted to the profitable culture of cotton, embracing an extent capable of producing at least one million of bales of the great staple. These lands, considering latitude and altitude, would possess a climate similar to that of Middle Tennessee and North Alabama, where cotton is already cultivated with great profit. If emancipation prevailed in Missouri, these lands would soon be cultivated in cotton by free labor, and its immense superiority over the servile system would soon be demonstrated. Such a proof of the superiority of free over slave labor, even in the culture of cotton, would soon have an immense effect in reconciling the South to the disappearance of a system so fatal to her
