The Emancipation Proclamation being, as we have seen, clearly constitutional, as a war measure, with a view to save the Union, was it, as such, wise and expedient? We have seen that the rebel South, even by conscription, when necessary, used slaves for military purposes, and those not used directly in that way are required to raise breadstuff's and provisions (instead of cotton), to supply the Confederate army. Indeed the debates of Congress for many years past, will show that the South boasted, not vainly, of their great military strength, because they declared that, while the slaves would be used in raising provisions to supply their forces, the whole white population capable of bearing arms could then be called into the field. This constituted, as they declared, their _great military strength_. And is it not then a most important war measure, to deprive them of that all-powerful and efficient weapon: which, we have seen, can only be done by emancipation? Now, let us suppose that while we refuse the use of the colored race, whether bond or free, in aid of the war, they are used for that purpose by the South, what would be the result? By the census of 1860, the whole population of the United States was 31,445,080, of which there were white, 26,975,575; free colored, 487,996; slaves, 3,953,760; total, of colored, 4,441,756, of which there were in the seceded States 3,653,110, and in the loyal States, 788,446. Add the whites in the seceded States, 5,449,463, would thus make the whole population of those States, by the census of 1860, 9,102,573. In the loyal States, the whole population was 22,342,507; of which 21,553,861 were white, and 788,646 colored. Now then, if the colored race, as we have seen, in the seceding States, are used for war purposes by them and not by us, the relative number of opposing forces would be as follows: Loyal States, 21,553,861; seceded States, 9,102,573; difference in favor of the Loyal States, 12,451,288. Now, to begin the process, add to the whites in the Loyal States the free colored, and the total number is 22,342,507; seceded States, 9,102,573; difference in favor of the Loyal States, 13,239,934. Continuing the process, if we deduct by the emancipation policy the whole colored population of the seceded States, the result would be, Loyal States, 22,342,507; seceded States, 5,449,463. But if, concluding the process, by the emancipation policy we not only deduct the colored race from the aid of the South, but add it in aid of the Loyal States, the result would be, Loyal States, 25,995,617; seceded States, 5,449,463; difference in favor of Loyal States, 20,456,154. Thus the policy opposed to emancipation and to the use of the colored race by us in the war, mates the difference in our favor as against the South only 12,451,288, whereas the difference in our favor by the emancipation policy of the President is 20,546,154. Deduct from this the above 12,451,288; final difference, 8,094,866. Thus we see that, by the
