That the Rebel authorities were cognizant of, and encouraged, this dastardly plot, cannot be distinctly proven. But, while they naturally would be likely, especially in the face of the storm of public exasperation which it raised throughout the Union, to disavow all knowledge of, or complicity in, the vengeful murder of President Lincoln, and to destroy all evidences possible of any such guilty knowledge or complicity, yet there will ever be a strong suspicion that they were not innocent. From the time when it was first known that Mr. Lincoln had been elected President, the air was full of threats that he should not live to be inaugurated. That the assassination, consummated in April, 1865, would have taken place in February of 1861, had it not been for the timely efforts of Lieutenant-General Scott, Brigadier-General Stone, Hon. William H. Seward, Frederick W. Seward, Esq., and David S. Bookstaver of the Metropolitan Police of New York--is abundantly shown by Superintendent John A. Kennedy, in a letter of August 13, 1866, to be found in vol. ii., of Lossing's "Civil War in America," pages 147-149, containing also an extract from a letter of General Stone, in which the latter--after mentioning that General Scott and himself considered it "almost a certainty that Mr. Lincoln could not pass Baltimore alive by the train on the day fixed"--proceeds to say: "I recommended that Mr. Lincoln should be officially warned; and suggested that it would be altogether best that he should take the train of that evening from Philadelphia, and so reach Washington early the next day." * * * General Scott, after asking me how the details could be arranged in so short a time, and receiving my suggestion that Mr. Lincoln should be advised quietly to take the evening train, and that it would do him no harm to have the telegraph wires cut for a few hours, he directed me to seek Mr. W. H. Seward, to whom he wrote a few lines, which he handed to me. It was already ten o'clock, and when I reached Mr. Seward's house he had left; I followed him to the Capitol, but did not succeed in finding him until after 12 M. I handed him the General's note; he listened attentively to what I said, and asked me to write down my information and suggestions, and then, taking the paper I had written, he hastily left. The note I wrote was what Mr. Frederick Seward carried to Mr. Lincoln in Philadelphia. Mr. Lincoln has stated that it was this note which induced him to change his journey as he did. The stories of disguise are all nonsense; Mr. Lincoln merely took the sleeping-car in the night train.
