At the same time the people believe that the Constitution gives the Government ample powers to put down the rebellion, as they have also given it unlimited resources of men and money. It would not be true to say that they have always been satisfied with the progress and success of the Government in the use of these powers and resources. There was doubtless a time when the public feeling demanded a more clear and decisive policy, and more vigor in the prosecution of the war. The people would like to have had the whole military system of the country revised and made more perfect. They would be better pleased if measures had been seasonably taken by which we might have had a well-organized and well-drilled army of reserve, two hundred thousand strong. Appreciating, however, the circumstances of the country at the opening of the war, the gigantic magnitude of the rebellion, and the immensity and complication of the problems pressing on the Administration, they have on the whole been disposed to be patient and trustful. And as long as they believe there is an honest, earnest purpose in the Administration to extinguish the rebellion by force of arms, they will sustain it. What they would do if ever they should come to the conviction that the national existence is in peril through incapacity, selfish personal ambitions or treachery on the part of the Administration, it is not necessary to predict. The conjuncture is not likely to arrive. Of one thing, however, you may be sure: the great loyal body of the nation have no quarrel with Congress or with the Administration for any of the measures that are the objects of denunciation by you and your associates, and they hold the men who utter these denunciations to be worse enemies to their country than the rebels in arms--morally far worse than the great mass of the misguided followers of the rebel chiefs. LETTER III. SLAVERY. Dear Sir: A considerable portion of your letter is taken up with a discussion of the rebel Vice-President Stephen's declaration touching slavery. In his speech at Savannah, Mr. Stephens, speaking of the new Government which the rebels had set up, says: 'Its foundations are laid, its corner stone rests upon the great truth that the negro is not equal to the white man; that slavery, subordination to the superior race, is his natural and moral condition.'
