"About this time *certain gentlemen in Canada began to be unenviably known. I make no charges against those whom I do not know, but simply say that the Confederate agents, Jacob Thompson, Larry McDonald, Clement Clay, and some others, had already accomplished enough villainy to make Wilkes Booth, on the first of the present year, believe that he had but to seek an interview with them."
