Mines.—By Census Tables, 9, 10, 13, and 14, Missouri produced, in 1860, pig iron of the value of $575,000; Illinois, none. Bar and rolled iron—Missouri, $535,000; Illinois, none. Lead—Missouri, $356,660; Illinois, $72,953. Coal—Missouri, $8,200; Illinois, $964,187. Copper—Missouri, $6,000; Illinois, none. As to mines, then, Missouri has a decided advantage over Illinois. Indeed, the iron mountains of Missouri are unsurpassed in the world. That Illinois approaches so near to Missouri in mineral products, is owing to her railroads and canals, and not to equal natural advantages. The number of miles of railroad in operation in 1860 was, 2,868 in Illinois, and 817 in Missouri; of canals, Illinois, 102 miles; Missouri, none. (Tables 38, 39.) But if Missouri had been a Free State, she would have at least equalled Illinois in internal improvements, and the Pacific Railroad would have long since united San Francisco, St. Louis, and Chicago.

Illinois is increasing in a progressive ratio as compared with Missouri. Thus, from 1840 to 1850 the increase of numbers in Illinois was 78.81, and from 1850 to 1860, 101.01 per cent., while the increase of Missouri from 1840 to 1850 was 77.75, and from 1850 to 1860, 73.30. Thus, the ratio is augmenting in Illinois, and decreasing in Missouri. If Illinois and Missouri should each increase from 1860 to 1870, in the same ratio as from 1850 to 1860, Illinois would then number 3,441,448, and Missouri, 2,048,426. (Table 1.) In 1850, Chicago numbered 29,963, and in 1860, 109,260. St. Louis, 77,860 in 1850, and 160,773 in 1860. (Table 40.) From 1840 to 1850 the ratio of increase of Chicago was 570.31, and from 1850 to 1860, 264.65, and of St. Louis, from 1840 to 1850, 372.26 per cent., and from 1850 to 1860, 106.49. If both increased in their respective ratios from 1860 to 1870 as from 1850 to 1860, Chicago would number 398,420 in 1870, and St. Louis, 331,879. It would be difficult to say which city has the greatest natural advantages, and yet when St. Louis was a city, Chicago was but the site of a fort.

Progress of Wealth.—By Census Table 36, the cash value of the farms of Illinois in 1860, was $432,531,072, and of Missouri, $230,632,126, making a difference in favor of Illinois of $201,898,946, which is the loss which Missouri has sustained by slavery in the single item of the value of her farm lands. Abolish slavery there, and the value of the farm lands of Missouri would soon equal those of Illinois, and augment the wealth of the farmers of Missouri over two hundred millions of dollars. But these farm lands of Missouri embrace only 19,984,809 acres (Table 36), leaving unoccupied 23,138,391 acres. The difference between the value of the unoccupied lands of Missouri and Illinois, is six dollars per acre, at which rate the increased value of the unoccupied lands of Missouri, in the absence of slavery, is $148,830,346. Thus it appears, that the loss to Missouri in the value of her lands, caused by slavery, is $340,729,292. If we add to this the diminished value of town and city property in Missouri, from the same cause, the total loss in that State in the value of real estate, exceeds $400,000,000, which is nearly twenty times the value of her slaves. By Table 35, the increase in the value of the real and personal property of Illinois from 1850 to 1860, was $715,595,276, being 457.93 per cent., and of Missouri, $363,966,691, being 265.18 per cent. At the same rate of increase from 1860 to 1870, the total wealth of Illinois would then be $3,993,000,000, and of Missouri, $1,329,000,000, making the difference against Missouri, in 1870, caused by slavery, $2,664,000,000, which is more than double the whole debt of the nation, and more than twice the value of all the slaves in the Union.

The total wealth of the Union in 1860 exceeded $16,000,000,000. If this were increased $1,000,000,000 in time, by the augmented wealth of Missouri, and our revenue from duties and taxes should be $220,000,000, the increased income, being one seventeenth of the whole, would exceed $12,000,000 per annum; or, if the increase of wealth should be only $200,000,000, then the augmented proportional annual revenue would be $2,750,000, or nearly one eightieth part of the whole revenue.

By overthrowing the rebellion, the taxes to pay the national debt will be collected from all the States, instead of being confined to those that are loyal. The rebel Confederate debt, never having had any existence in law or justice, but having been created only to support a wicked rebellion, will of course be expunged by the reëstablishment of the Union. All the rebel States' debt incurred since the revolt, for the purpose of overthrowing the Government, will, of course, have no legal existence. Under the Federal Constitution, no State Legislature can have any lawful existence, except in conformity with its provisions, accompanied by a prior oath of every member to support the Constitution of the United States. These assemblages, then, since the revolt in the several States, calling themselves State Legislatures, never had any legal existence or authority, and were mere assemblages of traitors. Such is the clear provision of the Federal Constitution, and of the law of nations and of justice. It would be strange, indeed, if conventicles of traitors in revolted States could legally or rightfully impose taxes on the people of such States, loyal or disloyal, to overthrow the Government. Indeed, if justice could have her full sway, the whole debt of this Government, incurred to suppress this rebellion, ought to be paid by the traitors alone.

My next comparison will be that of the Free State of Pennsylvania with Virginia.

Virginia was a considerable colony when Pennsylvania was occupied only by Indian tribes. In 1790, Virginia was first in rank of all the States, her number of inhabitants being 748,308. (Census Rep., 120, 121.) Pennsylvania then ranked the second, numbering 434,373 persons. (Ib.) In 1860 the population of Virginia was 1,596,318, ranking the fifth; Pennsylvania still remaining the second, and numbering 2,905,115. (Ib.) In 1790 the population of Virginia exceeded that of Pennsylvania 313,925; in 1860 the excess in favor of Pennsylvania was 1,308,797. The ratio of increase of population of Virginia from 1790 to 1860 was 113.32 per cent., and of Pennsylvania in the same period, 569.03. At the same relative ratio of increase for the next seventy years, Virginia would contain a population of 3,405,265 in 1930; and Pennsylvania 19,443,934, exceeding that of England. Such has been and would continue to be the effect of slavery in retarding the progress of Virginia, and such the influence of freedom in the rapid advance of Pennsylvania. Indeed, with the maintenance and perpetuity of the Union in all its integrity, the destiny of Pennsylvania will surpass the most sanguine expectations.

The population of Virginia per square mile in 1790 was 12.19, and in 1860, 26.02; whilst that of Pennsylvania in 1790 was 9.44, and in 1860, 63.18. (Ib.) The absolute increase of the population of Virginia per square mile, from 1790 to 1860, was 13.83, and from 1850 to 1860, 2.85; whilst that of Pennsylvania from 1790 to 1860, was 53.74, and from 1850 to 1860, 12.93. (Ib.)

Area.—The area of Virginia is 61,352 square miles, and of Pennsylvania 46,000, the difference being 15,352 square miles, which is greater by 758 square miles than the aggregate area of Massachusetts, Connecticut, and Delaware, containing in 1860 a population of 1,803,429. (Ib.) Retaining their respective ratios of increase per square mile from 1790 to 1860, and reversing their areas, that of Virginia in 1860 would have been 1,196,920, and of Pennsylvania 3,876,119. Reversing the numbers of each State in 1790, the ratio of increase in each remaining the same, the population of Pennsylvania in 1860 would have been 5,408,424, and that of Virginia, 926,603. Reversing both the areas and numbers in 1790, and the population of Pennsylvania would have exceeded that of Virginia in 1860 more than six millions.

Shore Line.—By the Tables of the Coast Survey, the shore line of Virginia is 1,571 miles, and of Pennsylvania only 60 miles. This vastly superior coast line of Virginia, with better, deeper, more capacious, and much more numerous harbors, unobstructed by ice, and with easy access for so many hundred miles by navigable bays and tide-water rivers leading so far into the interior, gives to Virginia great advantages over Pennsylvania in commerce and every branch of industry. Indeed, in this respect, Virginia stands unrivalled in the Union. The hydraulic power of Virginia greatly exceeds that of Pennsylvania.
