The large amount of political information regarding the South and its resources which has been of late widely disseminated in the North, is a striking proof that, disguise the question as we will, the extension of free labor is, from a politico-economical point of view (which is, in fact, the only sound one), the real, or at least ultimate basis of this struggle. The matter in hand is the restitution of the Union, laying everything else aside; but the great fact, which will not step aside, is the consideration whether ten white men or one negro are to occupy a certain amount of soil. There is no evading this finality, there is no impropriety in its discussion, and it SHALL be discussed, so long as free speech or a free pen is left in the North. So far from interfering with the war, it is a stimulus to the thousands of soldiers who hope eventually to settle in the South in districts where their labor will not be compared with that of 'slaves,' and it is right and fit that they should anticipate the great and inevitable truth in all its relations to their own welfare and that of the country. We cheerfully agree with those who try with so much energy that Emancipation is not the matter in hand, and quite as cheerfully assent when they insist that the enemy, and not the negro, demands all our present energy. But this has nothing to do with the great question, whether slavery is or is not to ultimately remain as a great barrier to free labor in regions where free labor is clamoring for admission. That is all we ask, nothing more. The instant the North and West are assured that at some time, though remote, and by any means or encouragements whatever, which expediency may dictate, the great cause of secession and sedition--will be removed from our land, then there will be witnessed an enthusiasm compared to which that of the South will be but lukewarm. That this will be done, no rational person now doubts, or that government will cheerfully act on it so soon as the fortunes of war or the united voice of the people strengthen it in the good work. And until it _is_ done, let every intelligent freeman bear it in mind, thinking intelligently and acting earnestly, so that the great work may be advanced rapidly and carried out profitably and triumphantly.
