While Mr. Martin was shouting invectives against the President in Richmond there came into Mr. Jefferson’s hand a letter from a Mr. Graybill of Baltimore. Inquiry revealed that the writer was an old Revolutionary soldier who had set up as a flour merchant. According to the information reaching the President, Mr. Graybill was a man of respectable character whose word could be trusted implicitly. In his letter Mr. Graybill said that for more than a year it had been believed in Baltimore that Burr was engaged in some criminal enterprise and that Luther Martin knew all about it. In his haste to even the score with Martin the President was carried away by the Graybill letter. He proposed to Hay that a subpoena be issued to Graybill to appear as a witness against Burr and, while Graybill was on the way, Hay might be considering how best to use his testimony. Then the President put forward a fantastic idea. How about summoning Luther Martin as a witness against Burr, meanwhile holding Graybill ready to confront Martin? How about the prosecution moving to commit Luther Martin as _particeps criminis_ along with Burr? Graybill, Mr. Jefferson was assured, would fix upon him misprision of treason at least. Mr. Jefferson did return to realities sufficiently to admit that there might be some doubt whether the prosecution could legally examine a witness to discredit its own witness. He recognized, too, that lawyers considered themselves privileged from being forced to breaches of confidence. “At any rate,” concluded Mr. Jefferson, “his [Graybill’s] evidence will put down this unprincipled and impudent Federal bulldog, and add another proof that the most glamorous defenders of Burr are all his accomplices. It will explain why L.M. flew so hastily to the aid of his ‘honorable friend,’ abandoning his clients and their property during a session of a principal court in Maryland, now filled, so I am told, with the clamors and ruin of his clients.” The District Attorney, wisely perhaps, ignored these chimerical suggestions from the White House.
