Of those who were slaves at the beginning of the rebellion, full one hundred thousand are now in the United States military service; about one half of which number actually bear arms in the ranks; thus giving the double advantage of taking so much labor from the insurgent cause, and supplying the places which must otherwise be filled with so many white men. So far as tested, it is difficult to say they are not as good soldiers as any. No servile insurrection, or tendency to violence or cruelty, has marked the measure of emancipation and arming the blacks. Those measures have been discussed in foreign countries, and contemporary with such discussion the tone of sentiment there is much improved. At home the same measures have been fully discussed, and supported, criticised, and denounced, and the annual elections following are highly encouraging to those whose official duty it is to bear the country through this great trial. Thus we have the new reckoning. The crisis which threatened to divide the friends of the Union is past. Looking now to the present, and future, and with reference to a resumption of national authority within the States wherein that authority has been suspended, I have thought fit to issue a Proclamation, a copy of which is herewith transmitted. On examination of this Proclamation it will appear, as is believed, that nothing is attempted beyond what is amply justified by the Constitution. True, the form of an oath is given, but no man is coerced to take it. The man is only promised a pardon in case he voluntarily takes the oath. The Constitution authorizes the Executive to grant or withhold the pardon at his own absolute discretion, and this includes the power to grant on terms, as is fully established by judicial and other authorities. It is also proffered that, if in any of the States named a State Government shall be, in the mode prescribed, set up, such Government shall be recognized and guaranteed by the United States, and that under it the State shall, on the constitutional conditions, be protected against invasion and domestic violence. The constitutional obligation of the United States to guarantee to every State in the Union a republican form of government, and to protect the State, in the cases stated, is explicit and full. But why tender the benefits of this provision only to a State Government set up in this particular way? This section contemplates a case wherein the element within a State favorable to a republican government, in the Union, may be too feeble for an opposite and hostile external to or even within the State; and such are precisely the cases with which we are dealing.
