SIR,--In answering your letter of the 9th, which desired a communication of one to me from General Wilkinson, specified by its date, I informed you in mine of the 12th that I had delivered it, with all other papers respecting the charges against Aaron Burr, to the Attorney General, when he went to Richmond; that I had supposed he had left them in your possession, but would immediately write to him, if he had not, to forward that particular letter without delay. I wrote to him accordingly on the same day, but having no answer, I know not whether he has forwarded the letter. I stated in the same letter, that I had desired the Secretary at War to examine his office, in order to comply with your further request, to furnish copies of the orders which had been given respecting Aaron Burr and his property; and in a subsequent letter of the same day, I forwarded to you copies of two letters from the Secretary at War, which appeared to be within the description expressed in your letter. The order from the Secretary of the Navy, you said, you were in possession of. The receipt of these papers had, I presume, so far anticipated, and others this day forwarded will have substantially fulfilled the object of a subpœna from the District Court of Richmond, requiring that those officers and myself should attend the Court in Richmond, with the letter of General Wilkinson, the answer to that letter, and the orders of the departments of War and the Navy, therein generally described. No answer to General Wilkinson's letter, other than a mere acknowledgment of its receipt, in a letter written for a different purpose, was ever written by myself or any other. To these communications of papers, I will add, that if the defendant supposes there are any facts within the knowledge of the Heads of departments, or of myself, which can be useful for his defence, from a desire of doing anything our situation will permit in furtherance of justice, we shall be ready to give him the benefit of it, by way of deposition, through any persons whom the Court shall authorize to take our testimony at this place. I know, indeed, that this cannot be done but by consent of parties; and I therefore authorize you to give consent on the part of the United States. Mr. Burr's consent will be given of course, if he supposes the testimony useful.
