'The secession sympathizers in the North have two favorite dodges for the service of their friends, the enemy. The first is, to magnify the numbers of the rebel forces, placing them at 500,000 men, whereas they never have had above half as many men in the field, all told, and counting negroes as well as white men. The other is, to magnify the cost of the war on the side of the Federalists. They tell us that our public war-debt, by the close of the current fiscal year, June 30, 1862, will be $1,200,000,000, (twelve hundred million dollars.) They know better than this, for that debt will, at the date named, be not much above $620,000,000, which would be no greater burden on the country than was that which it owed in 1815, perhaps not so great a burden as that was. People should not allow themselves to be frightened by the prophecies of men who, if they could be sure of preserving slavery in all its force, would care for nothing else.' It is always easy to make up a gloomy statement, and this has been done of late to perfection by the demo-secessionists among us. It is an easy matter to assume, as has been done, the maximum war expenditure for one single day, and say that it is the average. It is easy, too, to say that 'You can never whip the South,' and point to Richmond 'bounce' in confirmation. It will all avail nothing. Slavery is going--of _that_ rest assured--and the South is to be thoroughly Northed with new blood. _Delenda est Dixie._ Our 'private' readers in the army--of whom we have enough, we are proud to say, to constitute a pretty large-sized public--may rest assured that accounts will not be settled with the South without very serious consideration of what is due to the soldier for his services 'in snatching the common-weal from the jaws of hell,' as the Latin memorial to Pitt, on the Dedham stone hath it. It has been said that republics are ungrateful; but in this instance the adage must fall to the ground. The soldier will be as much needed after the war, to settle the South, 'North it,' and preserve the Union by his intellect and his industry, as he now is to reestablish it by his bravery.
