As to our personal attendance at Richmond, I am persuaded the Court is sensible, that paramount duties to the nation at large control the obligation of compliance with their summons in this case; as they would, should we receive a similar one, to attend the trials of Blannerhassett and others, in the Mississippi territory, those instituted at St. Louis and other places on the western waters, or at any place, other than the seat of government. To comply with such calls would leave the nation without an executive branch, whose agency, nevertheless, is understood to be so constantly necessary, that it is the sole branch which the constitution requires to be always in function. It could not then mean that it should be withdrawn from its station by any co-ordinate authority.

With respect to papers, there is certainly a public and a private side to our offices. To the former belong grants of land, patents for inventions, certain commissions, proclamations, and other papers patent in their nature. To the other belong mere executive proceedings. All nations have found it necessary, that for the advantageous conduct of their affairs, some of these proceedings, at least, should remain known to their executive functionary only. He, of course, from the nature of the case, must be the sole judge of which of them the public interests will permit publication. Hence, under our Constitution, in requests of papers from the legislative to the executive branch, an exception is carefully expressed, as to those which he may deem the public welfare may require not to be disclosed; as you will see in the enclosed resolution of the House of Representatives, which produced the message of January 22d, respecting this case. The respect mutually due between the constituted authorities, in their official intercourse, as well as sincere dispositions to do for every one what is just, will always insure from the executive, in exercising the duty of discrimination confided to him, the same candor and integrity to which the nation has in like manner trusted in the disposal of its judiciary authorities. Considering you as the organ for communicating these sentiments to the Court, I address them to you for that purpose, and salute you with esteem and respect.

TO GEORGE HAY.

Washington, June 19, 1807.

Dear Sir,—Yours of the 17th was received last night. Three blank pardons had been (as I expect) made up and forwarded by the mail of yesterday, and I have desired three others to go by that of this evening. You ask what is to be done if Bollman finally rejects his pardon, and the Judge decides it to have no effect? Move to commit him immediately for treason or misdemeanor, as you think the evidence will support; let the Court decide where he shall be sent for trial; and on application, I will have the marshall aided in his transportation, with the executive means. And we think it proper, further, that when Burr shall have been convicted of either treason or misdemeanor, you should immediately have committed all those persons against whom you should find evidence sufficient, whose agency has been so prominent as to mark them as proper objects of punishment, and especially where their boldness has betrayed an inveteracy of criminal disposition. As to obscure offenders and repenting ones, let them lie for consideration.

I enclose you the copy of a letter received last night, and giving singular information. I have inquired into the character of Graybell. He was an old revolutionary captain, is now a flour merchant in Baltimore, of the most respectable character, and whose word would be taken as implicitly as any man's for whatever he affirms. The letter writer, also, is a man of entire respectability. I am well informed, that for more than a twelvemonth it has been believed in Baltimore, generally, that Burr was engaged in some criminal enterprise, and that Luther Martin knew all about it. We think you should immediately despatch a subpœna for Graybell; and while that is on the road, you will have time to consider in what form you will use his testimony; e. g. shall Luther Martin be summoned as a witness against Burr, and Graybell held ready to confront him? It may be doubted whether we could examine a witness to discredit our own witness. Besides, the lawyers say that they are privileged from being forced to breaches of confidence, and that no others are. Shall we move to commit Luther Martin, as particeps criminis with Burr? Graybell will fix upon him misprison of treason at least. And at any rate, his evidence will put down this unprincipled and impudent federal bull-dog, and add another proof that the most clamorous defenders of Burr are all his accomplices. It will explain why Luther Martin 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, as I am told, with the clamors and ruin of his clients. I believe we shall send on Latrobe as a witness. He will prove that Aaron Burr endeavored to get him to engage several thousand men, chiefly Irish emigrants, whom he had been in the habit of employing in the works he directs, under pretence of a canal opposite Louisville, or of the Washita, in which, had he succeeded, he could with that force alone have carried everything before him, and would not have been where he now is. He knows, too, of certain meetings of Burr, Bollman, Yrujo, and one other whom we have never named yet, but have him not the less in our view.

I salute you with friendship and respect.

P. S. Will you send us half a dozen blank subpœnas?

Since writing the within I have had a conversation with Latrobe. He says it was five hundred men he was desired to engage. The pretexts were, to work on the Ohio canal, and be paid in Washita lands. Your witnesses will some of them prove that Burr had no interest in the Ohio canal, and that consequently this was a mere pretext to cover the real object from the men themselves, and all others. Latrobe will set out in the stage of to-morrow evening, and be with you Monday evening.

TO GOVERNOR SULLIVAN.
