It is pleasant to see the process of reconstruction going on so well in New-Orleans under the bayonets of our troops. But neither in New-Orleans nor elsewhere has it any vitality save under Northern direction, aided by Northern industry. The hatred of the South for the old Union is insane, terrible, and ineradicable. The real secessionists will never come back, they will never be conciliated. They will oppose Union, oppose free labor, hinder our every effort to benefit them, and be our deadly foes to the last. We might as well abandon now and forever any hope of reconstruction to be founded on reformed secessionists. A large party there is--and it will, if properly protected, become much larger--who will join the Union for the sake of preserving their property. _But this party will not be increased a single man by our neglecting to punish those who have been active rebels_, while on the other hand it will dwindle to nothing if left exposed to temptation and enmity. We must proceed with the utmost energy, and our only hope is in a complete reoerganization of the South, by infusing into it Northern blood, life, ideas, education, and industry. And the only effective means of doing this will be to settle our army in the South. The task before us is a tremendous one, but so is the war, and we must not flinch from it. We have come to an era of great ideas and great deeds, such as rarely overtake nations in history, and which when they do, either crush them to the dust or elevate them to the topmost pinnacle of glory. Petty expediency, timid measures, small politics, will no longer help this country. There is a great cause of evil in America--slavery--which is destined to disappear, and which _will_ disappear whether we legislate for or against it. It _is_ disappearing now under the influences of the war. Beyond it lies the equally great evil of Southern hatred, inertia, laziness, ignorance, and depravity. We must learn to live in the great ideas of making all this disappear before superior intelligence, industry, and humanity. The great principles of free labor, scientific reforms and culture, the enlargement of capital, the feeding and teaching the poor, should become as a deep-seated religion in our hearts, and we should live and labor to promote this great and holy faith which is in reality the practical side of Christianity--that great shield of the poor. To extend these doctrines over the whole continent is a noble mission, and one not to be balked or hindered by foolish scruples or weak pity for a pitiless foe.
