The statement of Clay that he had never known any of the persons accused and convicted of participating in the assassination of President Lincoln is shown to be false by the evidence of Richard Montgomery, as reported in the testimony taken by the military commission. Montgomery says I have seen Lewis. Payne, the prisoner at the bar, in Canada. I saw him at the falls in the sum mer of 1864. I saw him again and had some words with him at the Queen's hotel in Toronto. I had had an interview with Mr. Thompson, and on leaving the room I met this man Payne in the passage-way talking with Mr. Clement C. Clay.
