From the consideration given by the rebel President, as shown by these careful and favorable endorsements, would it be unreasonable to conclude that Lieutenant Alston was granted the interview that he desired, and that, armed with the permission and authority of the rebel chief, he became one of the active participants in the closing scenes of the drama? We have other evidence that at this very time the mind of Jefferson Davis was turned in this direction, and that he was inciting his agents in Canada to turn their attention to a grand political scheme of wholesale assassinations. To show the moral obtundity of the political stay-at-home-and-fight rebels about this time, I will reproduce an advertisement of this proposition to assassinate President Lincoln and the other civil officers of the government, that was published in the _Selma_ (Alabama) _Dispatch_, in December, 1864, under the caption-- "MILLION DOLLARS FOR ASSASSINATION "One million dollars wanted to have peace by the 1st of March. If the citizens of the Southern Confederacy will furnish me with the cash, or good securities for the sum of one million dollars, I will cause the lives of Abraham Lincoln, William H. Seward, and Andrew Johnson to be taken by the 1st of March next. This will give us peace, and satisfy the world that cruel tyrants cannot live in a land of liberty. If this is not accomplished, nothing will be claimed beyond the sum of fifty thousand dollars in advance, which is supposed to be necessary to reach and slaughter the three villains. I will give, myself, one thousand dollars towards this patriotic purpose. Every one wishing to contribute will address Box X, Cahawba, Alabama. December 1st, 1864." This advertisement was proven by compositors in the _Dispatch_ office to have been put in that paper by Mr. G. W. Gale, a lawyer of considerable reputation, and that the copy was in his handwriting, which was well known at that office. My impression is that several of the Richmond papers reproduced this advertisement, as also many other papers in the Confederacy. The treasonable purpose to overthrow the Constitution by the assassination of the President, Vice-President, and Secretary of State shows that the plan had been maturely considered in the light of the conditions that would render it most effective in securing the object in view, and that it was a deep political scheme to give the rebellion a new lease of life, and put it on its feet again under more favorable conditions for success. I have already given incidentally, and in a fragmentary way, glimpses of the testimony on which the charges of the government were founded. I will now present in a connected form the testimony bearing on the question.
