Those who look for an immediate restitution of Union feeling in the South, as a result of Federal victories, will be disappointed. It will be the result of a gradual movement--a movement resembling in every important particular that by which the secession sentiment was established in the interval between the election of Mr. Lincoln and the surrender of Fort Sumter. Operating particularly upon that class in society which is by nature passive rather than active, conservative rather than headlong, the movement, as in that case, will be at first slow and attended with many reactions, but the result will not be uncertain. Already the progress of the war has destroyed nearly all the motives by which the Union party of the South was formerly led to adopt the cause of secession. This great party, therefore, stretching through all parts of the South, forming an important element in the population of every village and county which threatened at one time with its passive resistance to overturn the whole scheme of the rebellion, stands now exposed to the full influence of the reactionary tide which has now begun to set back toward the Union. The change may not be at once, but the same motive which led the Union man of Tennessee to return to loyalty, will prove equally effective with his whole party, wherever distributed. SHAKSPEARE FOR 1863. 'O England!--model to thy inward greatness, Like little body with, a mighty heart,-- What might'st thou do, that honor would thee do, Were all thy children kind and natural! But see thy fault! the SOUTH in thee finds out A nest of hollow bosoms, which it fills With treacherous crowns! they would o'erthrow our country, And by their hands the grace of Freedom die, If hell and treason hold their promises.' _Henry V_, Act II, Scene i. THE UNION. V. ILLINOIS AND MISSOURI COMPARED. My previous numbers, comparing the progress, in the aggregate, of all the Slave States, with all the Free States, of Massachusetts and New Jersey, with Maryland and South Carolina, and of New York with Virginia, demonstrate the fatal effect of slavery upon material advance, and moral and intellectual development. In further proof of the uniformity of this great law, I now institute a similar comparison between two great neighboring Western States, Missouri and Illinois. The comparison is just, for while Missouri has increased since 1810, in wealth and population, much more rapidly than any of the Slave States, there are several Free States whose relative advance has exceeded that of Illinois. The rapid growth of Missouri is owing to her immense area, her fertile soil, her mighty rivers (the Mississippi and Missouri), her central and commanding position, and to the fact, that she has so small a number of slaves to the square mile, as well as to the free population.
