On Saturday, August 17th, 1850
Lincoln writes to S. R. Lowry about case involving title to land. "The trouble with this deed was, that the plaintiff proved it to be a forgery; and I see no way in which the defendants can ever succeed unless they can somehow prove that this deed is not a forgery. This is the whole story. The case can not be gained by much talking." Abraham Lincoln to Samuel R. Lowry, 17 August 1850, CW, 2:92-93.
